[Q] Any tips to improve connectivity? - Verizon Galaxy Note 3 Q&A, Help & Troubleshooting

Even on MJ7, my Wifi and LTE connections are unreliable. This is really my only issue with this phone now, and it is very frustrating. I'm showing a pretty consistent 3 bars/-95 dBm, and though calls and texts work great, I get awful data performance. I never had this issue with my last phone on Verizon (Galaxy Nexus). On the wifi front, it just randomly dies, even just a few feet from the router. I'm not convinced that a replacement phone is going to help matters...
Any ideas? I'm about to the point of ditching this phone for a different model...

same thing here. WiFi sucks, even with a strong signal I.e. in the same room as the router. I'm not noticing it as much on LTE, but then again I'm not using that as much anyways. Even as I am making this post, the "WiFi connection is unstable" just popped up, with a full signal showing on WiFi.

I also have same problem. Wifi unstable issue happens when my note 3 have no reception. Some post says delete cache from recovery but didn't helped for me. Some post says if you have adaway then you will have similar problem. Also turning off Auto network switch option from Wifi Advenced option will help too.
But none of above worked for me

The culprit for me was AdblockPlus. After uninstalling, all "Internet connection is unstable" messages went away. I am now using Adaway with no problems.

On a hardware level, the best i can think of is to add one of those sticky antenna boosters on back of battery cover but didn't try it yet
On a software level, i imagine that there must be some android equivalent to increase the tx power of the antenna, but not sure how
Hopefully someone can chime in with something concrete since many of us are having weak data coverage in major cities

This might be a contributing factor to our slow LTE speeds: Verizon's CFO admitted that VZW's LTE network in big cities is "strained". I guess the good news is that it should get better by 2015...
Certainly if you're not in a large city this may not apply to you. I'm in San Francisco most of the day and I can confirm that LTE speeds here are ridiculously low, even with a strong connection I am lucky to get 6-7 mbps download and around 500 kbps upload.

I went to the Verizon store last night, and the guy said to call 611 and report the LTE issue. I'll try that today.
The Wifi issue is super frustrating. I'll be in the middle of the most mundane things, and the connection just drops, making me wait a minute or so while it reconnects.

I'm not even in a major city. I'm getting speeds like 0.10 mbps where I work, completely awful. I'm leaving Verizon altogether if they can't do better than that. I know that this spot is not the norm, but it's my workplace. If I need it to work reliably somewhere, it's here.

MJ7 seems to have given me poor connection all the way around. Why verizon put on "improved connectivity" on their OTA is beyond me. Its worse if anything. Most of the time in my workplace I cant even update an app because the DL time is like 10 minutes for a 3mb app. Thats with 3 bars on 3g. Forget about a 4g connection in this building. However...my coworker on ATT has strong 4g even in this building.
Wifi is crap. It will be full connectivity and the in/out arrows lit....STILL freezes on loading pages and stuff. It would appear I have a strong fully connected working wifi signal but it just hangs there and pauses for like 1-2 minutes before even loading a webpage sometimes. Its becoming an extremely frequent event actually. Starting to really bother me. I never had any of those issues on MI9. These folks need to stop worrying about trying to patch up root with updates and causing other problems. Especially since the vast majority of users on their network are NOT rooted.
people dont root to steal from vzw anyway...or take advantage of services most of the time its just to customize their phone...and delete bloatware.
I dont see why they have such an agenda against root. Stupid.

Called Verizon, and they "reset my connection," and asked me to reboot. No change. The guy said the next step is a replacement phone. I doubt it will help, but I suppose if that's what they wanna do, I'll do it :/ I'll keep requesting replacements until they find a real solution...
EDIT: Called again. They put in a "trouble ticket" for the area. Let's see if it helps!

Was on MI9 stock rooted. I ODIN'd the MJ7 modem this morning cuz I couldn't stand my WiFi dropping off any time it wanted. Since then, my WiFi has been pretty stable. No complaints on LTE since I only tried this on a flashed phone (ie no LTE in the first place).

I spoke too soon. WiFi is still dropping off frequently.

For wifi, or should all check the wifi issues thread in this same forum. Worked for me and now I'm getting the full 50mbps from my home router.

For those with LTE issues you might try turning on airplane mode to shut off all of your radios and then turn off airplane mode. I have had to do this many times on my Razr Maxx to reset the 4g radios when it gets stuck on 3g.

Things I've done to try to fix my WiFi disconnect issues:
1) Turn off WiFi power save feature via service menu.
2) Wiped cache and Dalvik cache.
3) Upgrade radio to MJ7 (ROM is Hyperdrive based on MJ7).
4) Changed from DHCP to static IP (as suggested by Samsung via online chat).
5) Turn off Auto network switch.
My very last option...which I've already done...contact Samsung for repair. I'm shipping it back for service.
Now I just need to find a fully stock ROM to ODIN first before shipping.

Error Code 67 while roaming driving me nuts

First off, I have NOT made ANY attempt to use the phone as a WiFi hotspot, and I do NOT live in a 4G area, so don't tell me that's my problem and send me on my way
About 11am PDT today my phone started giving me Error Code 67 (Data Call Failure) whenever I try to access the internet or data services from my office (my office has an 850 MHz repeater so I roam in the office). When I am outside or not in my office and the phone picks up a Sprint signal, everything is fine. As soon as I come back inside and my phone switches to roaming, Error Code 67. I've had two calls with Sprint so far...They're updating the provisioning servers or some such thing at the moment and are going to call me back when that's completed.
Has anyone else experienced this today or recently and if so did you find a resolution? I can't easily take the phone back to where I bought it and have them fiddle with it in person as that's 100 mi away.
Thanks!
I've had the same issue too. See it mostly when traveling and the signal strength changes. Not to much when I'm in one spot.
It's quite annoying. I turn the display off and on hoping to pick the signal back up. Makes me think it is a Sprint network problem especially since I've now confirmed someone else has the problem too.

Well, they've got me fixed up again. Also while I was on the phone the gentleman helping me out received an interoffice message stating a server responsible for doing profile updates (Device Configuration message) on the EVO had gone down, so they're failing right now.
I have been getting it as well. I thought it was the roaming hack but I don't believe that is the case. Think it's just something on Sprints network.
I have gotten it too on both of my EVO's....I guess it's not just me

Yeah I read through that whole thread and it seems a fair amount of people have had this happen today. And as I wrote in that thread some service at Sprint related to sending out new PRLs and profiles to our phones went down as well.
I had the same problem yesterday my 3g suddenly went out with the 67 error but 4g still worked. I called sprint and they reset something on their end and after programming itself it w.ent away and my 3g data speed saw a nice speedbump
I've had this issue a few times with my Evo. Every time it has happened to me, I've had little or no signal.
What I think is happening is that the phone begins to authenticate itself with the data servers but then I lose reception, which causes the authentication to fail, hence the error message.
I _think_ I've had this happen on my Hero too.
yeah, (don't quote me on this, i may be wrong) i think error 67 is in regards to no data hookup, and if your phone is set to not get data during roaming, or to dilly dally about it (maybe roam guard?) (check settings > wireless and networks > mobile networks), it'll give you that error
I too had this issue for a while today. It was annoying the crap out of me.
same thing happened to me today, for some reason i wasn't able to get anything but a weak roaming signal at work all day. i called sprint, they wiped my phone and i still wasn't able to do the profile/prl update. i was able to do it once i left the building, of course i had to start with a blank slate on the phone. i'm hoping that after the updates i get a better signal in the building, otherwise i can't keep the phone and will have to return it for a (gag) iphone. after 3 days with a vastly superior OS that would be a tough thing to do.
Mine is def. not the Roam settings... That's the first thing I do is turn off Roam guard, call guard, special roam ring...etc. due to me having almost no signal at work.
I had this issue when I changed to the Alltel PRL. I rebooted, then ran the PRL update. It took a while to do, but once it got the Sprint PRL everything was fine.
-Midnigh7-
I had the same issue yesterday around the same time as the OP. Seems that maybe Sprint was having issues. Anyway, phone is back working and roaming today and even roaming 3G in the DC metro which is Verizon and was never Alltel AFAIK, so that's cool. Actually, some stations have Sprint in them, but others are Verizon and I had 3G Roaming in them today, so I was pleasently surprised, hope it sticks.

Odd 4G note

I'm in a pretty good area for 4G, so I've been turning it on when I leave the house lately...but recently, I've noticed something odd. While I get pretty good download speeds on speedtest.net, and it downloads files very well, when I go to a website, it won't load the page. The status indicator will go halfway, 3/4 of the way, but then it will hang, and the page will never load. I tested this in an area, last night, where I was getting 8+ Mbps (New Brunswick, NJ), in both Dolphin, and the stock browser, same effect in both. Then I turned off 4G, and the same sites (I tested about 6-7) loaded just fine in 3G. Anyone else notice this fairly annoying quirk?
I'm in Brooklyn and I've experienced the same thing a couple of times. I chalked it up to the 4g roll-out testing in the area.
If it flips to 3G and back to 4G even for a second it can jack up a page. Does reloading help?
When I had my EVO I also found that when I had 4G enabled the GTalk service would only very sporadically make AND hold a connection.
Turn off 4G and reboot the phone and I was able to connect no problem.
I called Sprint a few times on it but the people I spoke with in advanced support didn't have a clue to rather than hope for a fix I decided to return the phone and wait to see how the official rollout went.

No, this isn't a case where it's switching from 4G to anything else. It's only when it's loading a website in a 4G area, with 4G on - and it actually seems to get worse as the 4G signal gets stronger. In my case, it's very repeatable.
I'm going to try deleting the cache, and see if that helps...
It's really not that big a deal, as it downloads any other file type, and does it very well, when in a 4G area, and websites load fine via 3G. It's just a little odd.
Oh, I guess it would be a problem if I wanted to view a website while talking on the phone...

Yeah, I've noticed the same issue. There is no performance gain on loading webpages it seems. I don't really get a chance to tether my pc often on 4G (other than letting files download in the car), so I can't vouch for that, but I do get better web page performance on 3G.
Anybody have any more insight into this issue? In the past I was able to access any site using 4g just fine, but lately, any site that uses flash will load 4/5 of the way and then completely stop. I am not a smart guy and have exhausted basically all of the resources I have. I have tried flashing an older Wimax, tweaking Wimax settings, uninstalling flash updates and nothing has worked. I guess if it really starts to bother me I will give Sprint a call, although it seems like people over here at XDA know just as much if not more about these things...and you guys wont make me unroot to talk about them.
Thanks.
I experienced same thing. I'm guessing it's the network issue(it's just not dependable in my experience), and not even use it for websurfing anymore. I think 3g is plenty for websurfing, and use 4g for tethering.
Go into wireless & Networks and turn off Mobile Network that will turn off 3g completely just use 4g by itself and you wont have to worry about it switching between the 2
Well, for me at least, the situation seems to have resolved itself...the past couple of days, I've been able to go to websites on 4g with no issues whatsoever. And as a bonus, the 4G coverage around my apt (which isn't even an official 4G area yet) is up to about 8Mbps! Nice.
My phone was doing that the other day too, I dont live in a 4g area. It was also going on being connected to wifi. My browser screen was also going black but the phone wasn't sleeping, I flashed another ROM and it was doing the same thing. It hasn't done it over the past few days now. I guess it worked itself out.

[Q] Atrix doesn't play with my at&t microcell

Anyone else having problems making and receiving calls when connected to a microcell? I occasionally get the red circle effect while connected to a cell and a wi-fi router. I’ve seen the threads on connectivity by I’ve not noticed any problems outside of my microcell area so I think this may be different issue. My blackberry (forgive me) plays fine with the same microcell so I don’t think that’s the problem.
been using the microcell with atrix for a month now, havent had any issues
Is your ATRIX an upgrade on a line that was working with the microcell before, or a new line? If it's a new line you have to add the number. My ATRIX is on an existing number and I have no issues with my microcell.
Same number, so I must have a problem. at&t offered to doa, I probably swap. Thanks
I just started having problems during calls, the call cuts out then comes back. My last call was about 3 minutes and it cut out for about 3-5 seconds.
I recently updated the software, Im wondering if this is causing issues with it cause this never happened before.
Yes, I am having the exact same problem with my atrix. I think it started after the latest OTA update. I have had to shutdown my microcell. Better to have a weak, flakey connection than no connection at all.
Gee, thanks AT&T for your terrific service
My two Atrix 4G phones don't seem to have any problems with the Microcell.

I also have disconnected my MicroCell at home and went back to low signal. I could hear the people I was talking to fine but they could not hear me at all. I notice the same thing at work when uploading, any kind of uploading on the network keeps people from hearing you.
My atrix seemed to play well with my MicroCell through various radios and ROMs, at most 1 reboot was needed for it to connect.
I have similar behavior, copy/paste from my post on moto's forum today. During calls everything seems to be fine.
I have a Microcell in my office. The 3G and EDGE signal is -100 or worse, so there's no conflict there. The wifi signal in my office is low, ~-80db, and often disconnects/reconnects. Every once in a while my Atrix (stock gingerbread) loses the microcell connection completely and continues to have no network connection. The wifi connection stays connected though. I have to enable and then disable airplane mode to get the connection back up.
Any ideas? I could set up a logcat, but given that this occurs once in a while (maybe 1-2x/day) the log file would be pretty huge.
We bought a microcell for our office and had terrible experience.
I am not sure if it's the device or if something else you need for it but if there was one person in office, it worked fine but as soon as other people came in, it stopped working. You just won't see microcell signal on your phone.
Also, if you come in the office talking on phone, microcell would not pick up. A lot of times we had to reboot. It created more issues than before so we just returned it.

Best Way to Test Signal

Can anyone suggest the best way to test cell signal on the S7 Edge? My wife and I both have the same phone, but hers consistently seems to report more bars in the same location. I've had calls drop quite often on the first dial and then they stay connected the second time I call. I'm looking to test both phones and see if it's all in my head or if there really is an issue with my device. Any help would be appreciated on an app to use or other way to test the two phones. Thanks.
did you try phone info fromthe play store.
under monitor it will tell your signal strength. I believe through its service menu you also preform a signal test.
Yeah, but those numbers don't mean anything to me. Other than saying moderate for level, it doesn't say much.
Edit: My wife is not home right now, so maybe I'll install this on both phones and see if there is a difference in the same location;. Just wondering what options are out there for testing.
when you look i phone info under signal strength the number tells how good your calling capability is,
It is measured in dBm.
average should be should be around -101 dBm for full bars depending on your provider.
compare it with your wife's signal strength.
Keep in mind that software plays a part, please check that base band version and csc is the same.
Different base bands and csc means that signal strength can vary.
These should be identical as these two items communicate with your phone provider re reception and transmission.
Phones are both stock. Same provider and same software version. I'm pretty sure I've got reception issues because of the dropped calls. Like I said, she's not home right now to test, but in looking at bars previously, she always seems to have more bars in the same location as me. My phone in our condo here is always around -111 to -120 (LTE). That is right on the cusp of bad from what I can tell. Not sure where to go from here. Really don't want to do a factory reset, but I've read it can help clear up problems like this. Not sure how. Might be a lemon, as I've only had the device since February.
i suggest you call your provider and ask them to reset your phone on their system.
It might cause a difference because of flushing out of any information that may have been related to issues on your account.

Hmmmm...not sure what this is or what it would do. Never heard of such a thing.
Just got another dropped call. Signal was about -114. I placed a call. While it was connecting, the signal went to about -130 and then to -102 and then dropped. On a second attempt, the signal went to -97 and it connected fine.
Normally when you call your provider to report a problem with your phone.
One of the things they do is to reset your account in case there is an issue in your file as well as doing other tests.
It is similar to you cleaning the cache on your phone from time to time as bits and piece of old files then to slow down your phone.
Try to swap the SIM cards and check what happens.
So this is an older thread, but the issue had been ongoing. Lots of things tried. New sim. Called Rogers (my provider here in Canada) and had them reset mobile connection settings on their end. Tried resetting on my end. Seemed to get better and then back to being an issue again.
Lately it had gotten worse. When I would drive home and park in our parking garage, I would immediately go into roaming mode and was no longer connected to the Rogers network. I was then connected to Rogers-EXT because I had enabled data roaming on my device, from a previous call to Rogers, it was their suggestion to try and keep connectivity, as it is included in my package. The phone would stay roaming as I rode the elevator and into my condo and then usually connect to WiFi and then eventually reconnect to the main Rogers network. Meanwhile this never happened on my wife's S7 Edge, going the same route from her vehicle. Same device, exact same settings, same software version, same updates, etc. Her's never entered roaming mode or got disconnected from the main Rogers network.
Lately, when mine had been entering roaming mode and after I entered my condo, it would stay connected to Rogers-EXT. No matter what I did, a reboot, turn roaming on and off, etc. I had to physically remove myself from the LTE network and then reconnect and register with the network, and then I would connect to the main Rogers network and stop roaming. This was all getting damn frustrating, especially since the same thing was not happening to my wife's phone.
One setting I had not read much about and had not tried was VoLTE. I went into settings and turned this off. I immediately started getting a bit better readings on signal strength as well as no roaming issues any longer at all. I could park, ride the elevator and get into my condo and stay connected to the main Rogers network without issue, exactly like my wife's phone. Funny thing is, VoLTE is ON, on my wife's phone.
I really have no idea why her's works and mine doesn't, other than a hardware issue on my device. I thought about sending my phone in, as I'm still under warranty until the end of December, but right now, everything is working as expected and I haven't heard call quality suffer at all, with the calls I've made so far. I really didn't want to have to wipe my device and send it in and deal with a loaner if I didn't have to. I only plan on keep the device until about August of next year anyway.
If anyone out there knows of why this was happening to my device and not hers or if you have any other suggestions as to how to fix this and re-enable VoLTE (although I don't think it's really that important), please let me know. Again, it sure seems like a hardware (antenna) issue to me.
Aaaaaaaaand nevermind. Worked fine for about 3 days and today it was roaming again after coming up from the parking garage. Ugh. Wish I knew for sure this was a hardware issue. Such a pain to send your phone in, use a loaner, set your phone all up again when you get it back.

lost cellular data

So, when I woke up this morning I noticed my cell signal strength icon was one I haven't seen before. I tried rebooting and toggling airplane mode. I also verified that my sim is working in another device. I attached a screen cap with the icon.
Noticed something similar with mine. I had to turn wifi off, restart to get LTE data (verizon) then turn wifi back on. If restarting with wifi on the LTE data doesn't register.
that didnt work for me
update: had to factory reset, looks like verizon doesnt like that essential ph1 wont take all their bloatware, etc. might have to return the phone if this keeps up
My data connection has also become very erratic - and I've lost voice+data (VoLTE connectivity) wholly yesterday. Worked fine with the activated SIM from my HTC 10 from the 31st to yesterday.. Now, not at all, I've not been able to restore it since.
Really don't want to return it, as I really like the phone, but this has nexus 5x issues written all over it for long term use...
Hoping essential can get a certification and an agreement with Verizon before my return window is over (or at all)..
Pretty disappointed in Verizon here.
Sent from my PH-1 using XDA Labs
Same here, another issue is that essential shipped my phone and within a day i had an email from essential saying that verizon certification is still in progress. verizon will probably not certify it with their system unless essential lets them install their monitoring crap all over the phone.

The Nexus 6P didn't have the bloat and worked fine.
My PH-1 works fine including Enhanced 4G LTE Mode.
What do you have selected for network type?
I have the first one selected because that's the only one that includes the various CDMA protocols, EVDO and LTE.
I see the same connectivity that I had with my Nexus 6P.
i have global selected, as it covers everything the phone can connect to. i had the first one selected but it wouldnt show the lte+, just regular lte. i also have Enhanced 4g lte mode on. it just happened to lose service earlier today. if it does it again, ill probably return it after a visit to vzw

I have the same settings as you, I had functional "enhanced 4G LTE" for the first 4 days as well... That ended yesterday morning abruptly, and I'm not able to bring it back.. There's more happening here.. How long has your device been on the Verizon network? Only a hunch - in a few days you won't have "enhanced 4G LTE" either, even though it'll still be checked, and provisioned for it.

Cellular network is not available
After 7 days my phone won’t make calls I can only use data I’m on sprint and it was working fine until today I call sprint they had no answers at all I email essential no answer now I can only use WiFi calling while home and axx out at work
So, upon further digging I found a place to look at some more in-depth stuff relating to signal stuff. I did some fooling around and switched it from unknown to lte/cdma/umts auto (prl) and it seemed to work after a few moments of time. Though it seems have gone back to t he unknown state again but is working normally for me now, so maybe it was changing states and then a reboot?
How I got to this screen was by punching *#*#4636#*#* into the dialer, and went to phone info
I'm having a similar issue. I often lose my signal. I will have the full triangle/bars but no label of the signal(LTE+/LTE/3G/1x/etc....) and no cellular data at all.
The only way I can get it to return is to restart the device. Happens a few times a day, can't be 100% sure why, but it often appears to be when switching from WiFi -> Cellular only.
I have Verizon, I have had a Nexus 6 and then a Pixel XL for the past 3 years, never once had this issue.
I had constant disconnects and lost of service with my Tmo sim. Tried my Xfinity (VZW) sim and it was great until this morning. Complete lost of service. Airplaned mode on and off, connected to old school RTT 1x.... lol This phone's cellular just plain suck for a lot of us regardless of carrier. Not sure if we just have bad phones because apparently there are those who claim they have great service and connection.
I'm having this problem with Verizon. Seems like if I'm on wifi for a long period it only connects to 1x and putting in airplane mode and stuff won't get it to re-connect to to LTE. Only a reboot seems to fix the problem.

Necro post here but chiming in that I have the same problem with Verizon LTE. Happens when I'm moving long distances in car too. Suddenly just drops LTE and only a reboot will bring it back.

You might check out my post from the Oreo Beta thread... I was having some goofy signal issues early on which I've pretty much cleared up by doing what I mentioned here. Someone touched on it briefly earlier but only mentioned monkeying around with the settings, said nothing about picking up a new PRL.
I state this in that post too, but just in case: I offer this with no express intent of warranty, if you screw up your device, it's on you.

I just changed it from global to LTE/WCDMA and I got LTE back almost immediately. Was weird and global had been working for me for awhile now so not sure what happened in the past few days...

I had, right after writing this, tried *#*#4636#*#*
I set it to global as instructed in another post. The next time I drive a distance in the car I'll have to see if I have the same issue that only a reboot would fix again.
Thanks
I had the same issue and I resolved it a little differently than the previous posters. I turned on adb debugging and logged into adb shell and user-disabled com.redbend.app. This stops the Sprint oma-dm service from running. After doing this I no longer have the issue of my device not reinitializing lte after sleep or 3g.
I have essential on vzw but my only issue is my device won't connect to 4G. If I change network to LTE I get full 4G service but I'm unable to make phone calls. Went into vzw store and they told me you didn't get the phone from us so we cant help you. Day 14 fml
On Xfinity mobile, I had similar issues. Great LTE but sometimes calls just don't work at all. I mess with various settings and it'll work for a bit then so again. Gave up and ported over to Sprint for the free unlimited year which is still probably not worth it. Should've kept with Xfinity Mobile. Lol
