Non-broadcasting WIFI Doesn't Show Up or Automatically Connect - Samsung Galaxy S10+ Questions & Answers

Hello,
I posted a similar question in the General Android forums as well in case it was an Android issue. This occurred on two different S7s as well with two variants T-Mobile and Verizon versions. Got my new S10+ and it connected fine after Samsung Switch copied everything from my old S7. After the first security update which was the March 2019 version it started to exhibit the same problems that my S7s had where it would not connect to our home network nor show in the list of networks to connect to. Only time it would show is when already connected to a different network that (xfinifywifi in this case). My home network is a nonbroadcasting network and would be the only difference. This was never a problem before the updates. A new May update just rolled out but it did not fix this problem. Has anyone else run into this issue?
Thanks,
Jay

If You Cannot Access Google From Your Verizon 10.1 READ THIS

I have gone through three Verizon Samsung Galaxy Tab 10.1's in the past two days (since the Verizon release).
PLEASE NOTE: this only pertains to Verizon devices while trying to access Google pages using your device's DATA PLAN.
EVERYTHING works fine when you are connected via WiFi.
The first time I opened the browser, it tried to auto-log me into the default Verizon/tablet Google webpage. It never got there. I tried to access other pages in Google until I tired myself out. I tried installing Dolphin, Firefox, etc and still no go. I then tried connecting to WiFi and was able to access Google, so I figured this was probably a 4G issue. So I decided to call Verizon as I was somewhat sad about my new toy. Verizon had no notes or information at the time except for wiping my device a few times. Nothing worked. I was advised to return it, as it was deemed defective by Verizon's Tech Support.
I brought my device in and swapped it out. This one did the exact same thing. I tried logging onto Yahoo and it worked though. I showed the Verizon staff inside the store (because they had been fiddling with it for over an hour) and they were very happy to see that I found a way to make it work. I then tried accessing other sites and it also worked. About 10 minutes later, the staff had checked their Tech Notes on their Intranet or whatever they use, and a note popped up about a very large number of other customers reporting this problem.
Verizon said that they had a server issue and that was why this was not visible in their "notes" earlier. They said they are working on the problem and should have a way to fix the problem very shortly. One of the Techs their said I would be lucky if it happened in the next update. So we will see what happens.
Again this is only affecting a small portion of the Verizon Tab 10.1 4g LTE users at this time. And only when you are connected to CDMA or 4G. If you are having these issues with Google while on CDMA 4G (your data connection), just use your WiFi and everything should work just fine.
Don't cry. It will all be okay.
PS: I would like to apologize in advance if this post is not in the proper section. I am sorry.

I personally do not have a Galaxy Tab (WiFi Only) for either the 7 or 10.1.
But my ex-wife has the WiFi Only version and she says that there is not as many processes running in the background on her WiFi Only Tab (compared to mine). I would have to guess that this has to do with the Provider, but I could be totally wrong.

I have the same issue...
I wanted to chime in on this post to let you know what I've found out and to also give you a background on the experiments I've conducted both locally and with the Verizon techs.
I purchased the new Samsung 10.1 4G LTE tablet 2 days ago and have the same issue where I can't access google.com or anything related to the google domain via a browser when connected to the cellular network. Over wi-fi it works fine, but not over the 3g network.
That being said, I called Verizon tech support (no one had been aware of any issues with the tablets), and explained what was happening. I was escalated to a very good tech who walked me through several tests. In addition, I had two people in my office that had other tablets (a Verizon Xoom and an iPad2). This setup the perfect test bed.
Here's what we found out:
1. My Samsung 10.1 4G LTE can connect to google.com via wi-fi (both via a router and cellular hotspot).
2. My Samsung 10.1 4G LTE cannot connect to google.com via the cellular connection.
3. We did a factory restore on the tablet but that had no effect.
4. I turned on the Samsung 10.1 hotspot and had the other tablets try to connect to google.com using my cellular connection to see if it was something on their server blocking the domain. Both their tablets connected successfully.
5. I downloaded both Firefox and Dolphin browsers to see if it was in the default browser. Both didn't load google.com.
6. Tested all the google apps on the Samsung and all worked via wi-fi and cellular connection.
The only thing I couldn't try was to load google.com inside a 4g network. I live in South Texas and the closest 4g network is 2 hours away.
So...
I was told to take back the device to where I purchased it and exchange it to see if it was the device. It took about an hour to see the local tech, so in the meantime, I though I would try the display tablets in the store to see if the problem existed with those.
All the Samsung 10.1 4G LTE devices didn't load google.com over the cellular network.
I felt like I had reached the limit of what could be done, but I still was interested to see if it would work in a 4g network.
So...
I had one of the techs call another Verizon store in San Antonio (a 4G environment) to have them load google.com.
IT WORKED!!!
My conclusion is that there is an issue with the tablet's software that is preventing google.com from loading via a 3g cellular connection. This explains why some people can get it to work (4g network) while others can't (3g network).
The tech went ahead and exchanged my device for a new one (which by the way, still didn't load google.com as expected) so he could send it back to Verizon and start the process of getting this rather embarrassing situation fixed...hopefully.
The ironic thing is, this only affects loading google.com and no other website. Being a google supported device, I would expect this to be resolved quickly.
I hope this has been helpful.
UPDATE: My 10.1 is working FLAWLESSLY now.
Thanks for the chime in. As I had said, the Tab worked fine with Google when connected to wifi, just not when connected to the Verizon network. That was the whole issue. The software issue seems to be a part of the issue, BUT I HAVE LEARNED THAT THE 4G LTE SIM CARDS MAY WELL ALSO BE A HUGE ISSUE (ALSO HOW THEY WERE INSTALLED).
The way the SIM card is installed could have been an issue, but there also could have been an issue with certain "batches" of 4G LTE cards that Verizon was given. To be perfectly honest, the first tablet I had that had this problem, I returned immediately and asked them to just replace my device and give me the card to take home so I could install it myself (I had been the only customer that day [opening day] to pickup a 10.1 and nobody there really knew how to set them up. They know the type of work I do and had no issue with it. I followed directions exactly as described, and still had the same issue.
It really disturbed me though when I had brought my first 10.1 back and they spent an hour into closing trying to figure out what was wrong (all 5 employees). The man who installed the card in the first place really wasn't even that sure if he had done it correctly. I don't think everyone was really too up-to-date on how to get these Tabs up and running with the LTE out of the box.
Verizon later told me that problems with the SIM cards themselves could be corrected without having to manually service the device.
Who knows.... All I know is that the issue is no longer a problem for me. If anyone is still having problems in this area, please try and give me any details you can besides what has already been said. This way I can forward the information to my colleagues at Verizon and Motorola and update them further.
PS: I had also just learned that if you lived in an area where 4G was not available, but was suppose to be in the very near future, you could have also had some "issues" with your 10.1. Nothing too specific, but there could be a handful of odd issues concerning new and upcoming 4G locations. That's about all I can really say.

Chiming in here. I've had the same issue with not being able access Google sites while on CDMA (LTE coming in November locally) since I purchased the GTab 10.1 LTE a week and a half ago. I have read posts on several forums with others having the same issue. After seeing this post today I tried once more using CDMA and it works. I have not made any changes or messed with the SIM card on my Gtab. Verizon must have done something on their end.

[Q] Wifi Slow on Galaxy S5 - Strange Issue, Please Help

Hi All,
I was wondering if someone can help me. I am having a bizarre problem on my Galaxy S5, which so far has stumped Verizon, Samsung and Time Warner Cable Tech Supports.
For some reason, when I'm connected to my home Wifi network, certain apps run very slow. Basically, if you open an app like Facebook, Instagram, or the Google Play Store, a lot of the icons, pictures and thumbnails all show up gray, and either don't come up at all, or take forever to load. As soon as I turn Wifi off and switch over to 4G, they all pop up almost immediately. I've also noticed this problem on Google Now. You tap the microphone, say a command and it gets stuck on "Recognizing..." for a long time, and quite often comes up with "Can't reach Google at the moment." Again, it's only certain apps. Other apps like my web browser app don't seem to be affected.
This doesn't make sense to me, because I also have a laptop and my girlfriend's Galaxy S III connected to my Wifi network and they don't have this problem. I've even busted out my old LG Spectrum 2 and sure enough, these apps load up lightning quick on it. I've done an internet speed test on my S5. On my Wifi I get a 19ms ping, download speeds of 18 MB/s and uploads pushing 2 MB/s. When I'm on 4G, the ping is 40ms, and the speeds are only 6MB/s and 0.7MB/s respectively, so the Wifi theoretically should be way faster.
I spent over an hour on the phone with Verizon and Samsung Tech Support, and after trying a ton of different things, including a Factory Reset, they determined it was probably the device. Since I'm under warranty, they sent me another one. I got it yesterday and tried it...yep, same problem.
Just out of curiosity, I tried it on the Wifi at my workplace. Wouldn't you know it, the problem isn't there. But, I don't understand what could be wrong with my home Wifi. I've got Road Runner Turbo internet from Time Warner w/download speeds up to 20MB/s. I've also got a really good modem/router that cost several hundred dollars. And, like I said the problem doesn't seem to happen on other devices.
I've searched the internet and have found almost nothing on this. Does anyone know of something I can try? Here's everything I've tried so far:
"Forgetting" my Wifi Network and Reconnecting
Resetting the Modem/Router
Clearing Data and Cache on Affected Apps
Phone Factory Reset
Trying with another Galaxy S5
Switching from DHCP to Static Connection on Phone
Switching DNS to Google's Addresses on Phone (8.8.8.8 and 8.8.4.4)
Tinkering with the Modem/Router Security Settings and even Disabling Security
Changing the Router Bandwidth Settings
Changing my Router's Broadcast Channel - Have Tried Several Different Ones
Calling my ISP and Upgrading to a Higher Bandwidth/Speed
Here's my hardware details:
Phone - Verizon Galaxy S5, Unrooted, Running Stock Kitkat 4.4.4
ISP - Time Warner Cable, Road Runner Turbo
Modem/Router - Motorola/Arris SBG6782-AC
Thanks so much in advance!
Watching with interest.
Have a similar situation with my s5 900f international running latest NeatRom.
Some days better than others even when using home sky fibre optic and no drop in speed from router.
Had to get a new router
Ok, so I finally fixed the problem...in a manner that I wish I didn't have to resort to, but it seemed like the only option.
Let me start by thanking Rukbat from Android Central. I posted this topic there too, and his response was very helpful. Here's a repost of it:
Talk to Verizon (the tech people in the back, not the sales associates) or the Time Warner people (same thing - tech people) and see if anyone has an old Linksys or D-Link wifi router you can borrow for a day. (I'm using a Linksys WRT54G at the moment, and in router years it's as old as George Washington's corpse.)
From years of experience, writing communications code, playing with my phone, routers - and looking at my calendar - I'm guessing a bug in KitKat that shows up only with some apps. My almost new Linksys EA4500 started showing this problem almost as soon as the phones updated to 4.4.2, but the apps all work fine on old routers.
If an old router solves the problem, you can get a refurb WRT54 (G or GS) for the $25 range on Amazon (or maybe TW has an old one they'll let you use with one of their modems).
The Facebook app works just fine on mobile data, AT&T hotspots, TMobile hotspots - but not on new Linksys (supposedly the best) routers, and I've heard reports of the same problem on the newer D-Link routers, also supposed to be top-of-the-line. (I actually left the app running for 12 hours once, just to see how long it would take to update. It's more than 12 hours, because it still hadn't done anything. But standing in the parking lot at a Sam's Club, with a barely usable AT&T hotsopt signal, it updates in a couple of seconds.) AT&T connected me to their in-store wifi (which is secured, so of course they deleted the connection after we checked it out) and Facebook updated immediately. Speedtest.com shows over 14mbps download and pings running from 15-50ms with my new router that doesn't work with facebook, so it's not the connection, it's not the wifi signal itself, it's either a problem with certain apps or a problem with the 4.4 wifi firmware. Play store downloads are slower on the new routers too, but not too bad. just noticeably slower. (If I set up a guest account on the router it works fine, though, so it's not a bad router. It's just a pain to have to sign into the guest account every so often.)
This is the reason systems analysts turn grey at a young age and have bald spots. Problems that don't seem to make sense, and people in a position to debug them who can't or won't. I can reproduce the problem at will (which is the difficult part of fixing a problem), but there's no one interested in fixing it.
I ended up just getting a different router, as he suggested. From what he's describing, it sounds like some routers just don't play nice with some newer phones, for no apparent reason at all, which is both discouraging and frustrating at the same time. And I've come to the conclusion that my router is one of them. After spending hours on the phone with technical support from Verizon, Time Warner, Arris and Samsung, no one could find a solution for me.
I will say that I did find some hints from other places online that tweaking certain router settings will fix this problem, but I think I kind of nipped myself in the **** by not doing my homework when I bought my Arris modem/router. This router is locked down pretty tight from changing certain settings. You can't disable IPv6, which some people say fixed the problem. Someone else suggested enabling IP tunneling, but I don't see this setting on my router. Somewhere else, I read that this is the same thing as Port Forwarding, but I really don't know what port you would have to forward to a phone. You can't even update the firmware on my router, as Arris only provides it to cable ISPs...and they won't push it to customer owned devices. I don't even know why they sell this model to the public if that's the case.
So anyway, I just bought a much cheaper Netgear router from Best Buy, and wouldn't you know it, it works great! I think that it even outperforms my Arris. I guess the moral of the story is be careful about what you buy.
Update - problem solved!!!
I cannot believe this. I managed to get my phone working yesterday with my old Arris modem/router. I didn't even have to tweak it, or try to disable IPv6 or anything.
It turned out that the problem was my phone's SIM card. When I first bought the phone, I ordered it online and I remembered that it came in the mail with a SIM card. But, when I placed the card in the phone, it wouldn't activate. I probably should have called Verizon at that point to ask what I should do, but I ended up just taking the SIM card out of my old LG phone, and putting it in the S5. It looked the same to me, so I didn't think it would matter.
Then, not too long ago, I noticed that certain apps were saying that I needed an "Enhanced SIM Card" to use them, so it got me thinking, maybe I should have used the card that came with the phone. I called Verizon, and sure enough, they said that the card that came with the phone used much more updated technology, which is a better fit for the phone. So, they got it activated for me, and now not only do all of my apps work, but the slow Wifi problem is gone too! I didn't even know that the SIM card can affect Wifi. But anyway, this is great! I can take my new modem back, now.
I would ask anybody who has this same problem if they are not using a SIM card that came with the phone. If you are, it could be that you need a new one or more updated one. I believe most carriers will give you a new one for free. You can also check to see if your card is outdated in a couple different ways. Try opening an app like Softcard, and if it says that you need an Enhanced card, then your card is outdated. Also, check the numbers on your SIM. According to Verizon, in the US, the card should have a handful of numbers, followed by FIVE zeroes. If there are any more than five, it is an older card. It might be different for different countries or carriers.
Hope that helps!
Grrrr....spoke too soon. It worked fine for about a week, but now it's doing the same thing again, even with the new SIM card. Switched back to the newer router. Guess it's something with the Arris router after all.

Cannot connect to school Wi-fi

I've had my S7 Edge (Verizon, Android 6.0.1, stock Samsung) for, a week, and have been trying to connect to my school's wi-fi with zero success. My attempt is met with:
"Authentication error. Credentials not valid. Incorrect password."
Settings
Security:
802.1xEAP
EAP method:
PEAP
Phase 2 authentication:
MSCHAPV2
Identity:
<my school username, which I have verified with my laptop, and school computers)
Anonymous identity
<none>
Password
<my password, which I have verified on laptop and school computers)
The phone is able to connect to my home Wi-Fi without issue.
I have been able to connect to the school's wifi with my S4 and my laptop with no problem.
I've rebooted the phone, "forgotten" the network several times (with rebooting before attempting to access again).
I've forgotten the network, shut off wifi, shut off the phone, drove to lunch, come back, restarted the phone, turned on wifi, sacrificed a goat (just kidding, NSA), and tried to reconnect, to no avail.
I've check with my IT dept, and they were unable to help. They are, for obvious reasons, unwilling to reboot the router to try that.
With stock Samsung, I'm unable to change wi-fi freq (or, at least, I haven't been able to figure out where to do that).
I've searched online for fixes, and searched through the forum, and haven't found anything I haven't already tried, or are unable to try (ie, router reboot).
I'm completely at a loss here. I'd really prefer not to use my data when there's a perfectly good wi-fi network available...
Any of you smart folk have an idea?
similar issue
I too am facing the same issue. With bit of research it looks like a bug in android 6.0.1 which was patched in later revisions of 6.0.1 which samsung have't updated.
https://code.google.com/p/android/issues/detail?id=188867
http://forum.xda-developers.com/nexus-6/help/broken-wifi-peap-android-m-marshmallow-t3221066
Apparently, there is a simple workaround if we have root, But we are stuck at this point.
I guess this problem could be solved only if Samsung updates the software with merges from newer versions of android or if we get root.
Anyways, post here if anybody finds a solution to this.
I may as well add a "Me too" to this one and a bit of more information.
For me, I have a Galaxy Note 4 for AT&T and it is stock and up-to-date, still connecting to the work WiFi (802.1x EAP -> PEAP username & password) with zero issues.
My Galaxy Note 4 with Verizon (work phone) WAS working until it got updated to 5.01 and then it broke the WiFi to 802.1x, just sits there and says connecting.
Phone (Verizon) got two more updates since then but nothing fixed it.
So, I had them upgrade my phone to the Galaxy S7 (not Edge) and lo and behold, STILL broken! And in the past three days, there has been two OTA updates to the phone, but neither one fixed the issue.
So, I would like to know if it is just Verizon, holding back the patches, or maybe I am lucky because I can still use my personal phone (AT&T) on the company WiFi?
If this is going to be a long drawn out battle to get Verizon to fix it, I think I have just enough clout to get my work phone moved to AT&T as I should not have to use my personal phone for work, even if it is not costing anything (WiFi).
Can anyone confirm the S7 for AT&T works ?
How about the Note 5 on Verizon? (probably not).
Waiting with everyone else. . .

International Tab A with S Pen

Found someone selling the international version of the Galaxy Tab A with the S Pen, model is SM-P585 for $160 and got him down to $130, haven't looked at it yet so don't know if it's in a different language or not, and obviously no warranty. But looks like it's the LTE model, won't be using it. Said it came from Korea, looking at the specs between the US version and Korean version looks the same except the Korean version has 32 gigs of ram vs 16. Only thing that worries me are updates down the road and compatibility with the app store. Will certain apps not load if it sees it as an international version?
hard to say
i did exactly what you are contemplating.
The unit i received boots and works fine via wifi. It does not work on wireless (cellular) networks, even though it has valid SIM card installed. Which is why i'm here, since i am going to try to flash firmware of a different region that has compatible bandplans to where i am. I've researched all that info on the web, and have chosen a "most likely" candidate.
The firmware it arrived with seems to be Singapore and Vietnam based. I'm going to try to flash Malaysian firmware and see what happens.
FWIW, the device will not upgrade via the built in upgrade option (in settings). It returns an error. Current android V 5.0, but i know htere is valid 6.0 firmware available. (which is what i'm going to flash).
I have verified using "System info for android " app, that it sees a network, but is simply not connecting. the curious thing about the situation is, that although the tablet will not connect to the cellular network, it does show the onscreen icon for network strength (which is very strong, 4 or 5 bars). So the device is recognizing a signal, but will not connect. I have used sim cards from several carriers, and "scanned" networks" which gives a list of expected locally available networks, but the device will not connect to any of them.
If anyone reading this has any ideas, i'm happy to hear them.
Good to know thanks. I don't plan on using it for the cellular part just WiFi, don't want to spend money on a data plan. I did find several sites that had marshmallow but you had to use odin I believe. Also found this thread incase it helps you.
https://forum.xda-developers.com/galaxy-tab-a/help/sm-p585-flashing-firmware-variant-t3498225
I had the Tab A 8.0 with S Pen (SM-P355) the international version capable of making phone calls. I don't think it was ever sold in the US. I had no problems loading any apps from the Play store, including banking apps and others that were regional or required authentication, like Uber.
The last version I received (before cracking my screen) was 6.0, pushed via OTA update.

Wifi hotspot not working

Hey Guys, I have a A2017G, running Android 7.1.1, security patch level 1 march 2017, V1.2.0b02. I'm running a dual sim setup, with a second sim just for data. Last night my house internet went unavailable so i figured i would just run a hotspot from my phone. Unfortunately i can turn the hotspot on , and my other devices can connect, but there must me a routing problem as they connect to the wifi but cant get internet through it, all of tem (and i tested 4 devices) give me a "connected, no internet" message. I searched around and found lots of people with the same issue but no solutions.
I tried running just one sim to test if it was a dual sim problem with no change. Also i used to do it with marshmellow with no issues and am not rooted.
Ahh and i poped the data sim on my old oneplus one and it worked flawlessly
Anyone of you had the same issue and/or have a solution?
