[Q] Intermittent WiFi disconnect - Nexus 7 Q&A, Help & Troubleshooting

Have done some searching and have not found this exact issue. Sorry if its a repeat. Also please excuse typos. N7 keyboard and me don't always see eye to eye.
I own 2 32 GB N7s (well one is my gf's) . Both purchased refurbished at the same time on woot. Both upgraded to 4.4. Mine was very quickly unlocked and rooted. Mine has a custom recovery (forget which right now) and multirom. Only other ROM is ubuntu touch.
Mine will randomly disconnect from WiFi. The interval varies from less than a minute to more than 10 between disconnects. The stronger the signal the less it occurs, but it will occur right next to a router. It also seems to occurs (or is more noticeable) when doing things that require more bandwidth, such as streaming or loading heavy pages.
Most often it will reconnect on its own, but I can normally speed the reconnect by turning WiFi off and on or forcing the reconnect in settings. I have tried multiple routers, and other devices on the network (android phones, laptops,and the other N7) do not exhibit this behavior.
I did have to reeplace my USB jack. And I was inside the n7 one other time, it got dropped and would not boot. The battery had shifted and come partially unplugged. The issues started well before the port replacement, but the drop was to early in my ownership to tell if it was the cause. If it is I can only assume that it would be weak signal. Probably from removing the case and there being a poor connection to the antennas, but signal strength shows about the same as the other n7 when side by side.
There is a precourser to the drop as well. Data will stop before the WiFi indicator greys out. If you catch it and look at the notification area you can often see the send I dictator but no receive before the disconnect.
Anyone have any ideas? Are there any logs that may hold clues? It is annoying when streaming in house to have to reconnect multiple times during a show, and then often restart the stream and fi d your place only to have it happen again. Gaming suffers to. For email and browsing it is not a major issue,but I would still love to try to fix it.
Thanks!

Hi brad we are on the same boat . Wifi unstable but the other phone working good. Ive tried update to 4.4.3, and wifi connected very fast but the problem still there. But now i change my router to docsis 2.0 by cisco (rented from tv cable) and now its working great event sometime youtube still buffering. Before that i used tplink 941nd router.
I hope this wil help.

N1 wifi Issues solved with Gingerbread

I have always had an issue with the wifi on my N1 when trying to connect to my router at home. Getting a connection use to be hit or miss, I would often try connecting over and over again with no success. Even when I did connect it would drop out as soon as the phone when into standby.
Well to my surprised after downloading/installing GB I went to attempt to get on wifi and it connected right away. I was shocked to say the least. I turned it off and tried it again and it connected again. Then I put the phone in stand by and it still stayed connected. Then I had to run to the store and left wifi on, when I got back to my apartment it connected again, no issues. This is completely awesome!
Froyo 2.2.1 fixed my major wifi issue (wifi going dead while the phone was asleep), but not the smaller issue where my connections would randomly disable themselves occasionally. I haven't seen that happen since Gingerbread though, so that's a good sign so far.
My only remaining issue with wifi is that the DNS cache still doesn't get flushed when switching to/from wifi to/from 3G/EDGE. This causes me frustration with our Exchange server which has a different IP on our LAN than it does on the public internet...
Congrats. I used to have problems, but I got a new router and it has been fine since. I used to get the "disabled" once in a while, but then I started using Auto Wifi Toggle, and never had another problem.
I know how you feel, it's nice when things work.

Really?! How come the same issue wasn't solved for me until gingerbread?
Now wifi is working just perfect Connects fast, sleeps when it should and transfers are awesome and rock solid
I had an issue with my home router and N1 where the N1 would connect, but after a bit of idle time, lose connection. It would re-try connecting only when I turned the screen back on and waited a good 10sec.
I was on 2.2, then 2.2.1, then 2.2.2
Now with 2.3.3 ...... my WIFI stays connected at home and at work... no hiccups at all.

I had exactly the same issue with my N1. Oddly, it got worse when I upgraded to a newer router (New D-Link with -n, compared to a 6yo Netgear with -g only) No idea why, but it did.
I finally got the OTA last night for Gingerbread and only now does it automatically connect and stay connected to WiFi like it should have.
My N1 is plain vanilla - no mods. For the 6+ months I've had the phone, it would constantly lose connection. I'd hit the WiFi button on the Power widget to turn off and on just to force it to reconnect to WiFi. 5 minutes later, I'd check my phone... back on 3G. I knew it was the phone, because I have plenty of other portable WiFi gadgets that stay connected just fine.
Whatever it is, I'm glad they fixed it.

WiFi Issue

Just got my Arc today. Connect up via wifi to various diff sources, same issue. After approx 2 mins, signal bars for wifi remain static, never move and connection issues occur. This happens on anything from market, web, gmail etc.
Repeatable on various diff routers, only way to recover is turn off wifi and reactivate it, then it will last another 2 mins.
Checked and running latest firmware. Faulty device?
Maybe, my wifi works fine.
Yeah starting to think that. Both my galaxy s, and iphone 4 stay connected all the time at decent rates. Watching the router stats the mac for the ARC just drops down to 1, then dies. Also noticing bad range, like anything more than 3m away from router and no signal.
Hi there. yes i have the same problem with my arc.... but not allways, yesterday when i was on market,downloading its stops at 40% and thats it, i must turn off wifi and turn back on, that will help..but after few minutes (downloading,browsing,facebook) it again stops,and again the same. But its not allways after 2 mins... one time is working fine without problems even one day is ok ,and sometimes is doing this. yesterday i get a error from arc something like that " error parsing packets" . And what i have noticed on 3G is doing the same, i tried to download yesterday the same file with 3G conection and it stops again. So i think this is not only wifi problem...i dont know.any clues?sugestions? sorry for my english xd
im at work atm.
The WiFi is pretty well known already, it happens also to me and quite a few other owners of the Arc. From my experience it is related to Youtube application or video playing/flash pages because most often it occurs when using them.
Sometimes I would be able to use the WiFi connection for more than a day without issue, while other times it stops working twice in 5 minutes. Pretty weird behavior, but I'm guessing it is a combination of a software issue and the newer support for draft n wireless connection.
Joy, its kind of a deal breaker for me
No WIFI issue whatsoever with my ARC
Software issue.

Wifi Issues

I'm having problems connecting to the corperate wifi with my Nexus 10, I've used an android tablet berfore on it, TF101 connected without any problems, I've seen issues reported with the Nexus 7 and Wifi, has anyone else had and issues connecting to WPA/EAP with Certifcate authentication.
The device is crrectly registered as it can connect to another SSID which uses the same mac database
Working fine for me, however I have been disconnected twice in the last 2 days,

Bump.
Any fix to this issue? We use WPA/EAS and I get "not in range". Some people got it to work and some didnt. there's an open bug being tracked on Google (Issue 34212) but no workable solution on the N10.
Having problems with optimium wifi. I have to sign in everytime, while on my phone/laptop its not needed.
I downloaded the wifi register app from optimium, but it can't sign in with that. Any solution?

My connection stays strong (max bars) when for example playing a youtube video, but after while the video endlessly buffers (or freezes) until, either I jump in and out of multitasking screen or restart the WiFi connection. It's as if it can't reinitialize the stream for some reason. I have the same problem downloading apps and other media, i.e. good signal, stable connection, but just seems to time out continuously. It's driving me mental, without reliable WiFi the device is next to useless. I'm hoping it's a software issue that will be addressed soon, but if not I suppose it's RMA time.

I had the same issue with YouTube last night. It took me a while to get the connection back at one point. I rebooted the device and the router and I eventually got my connection back. I would tend to think it is a combination of Android and the router that will eventually be worked out with an Android software update.

WiFi connection drops, have to reboot - Virgin hotspot

My Nexus 7 had no problem with wifi connections since I bought in right after they were first released. Last week, I bought a Virgin Broadband Mobile Hotspot to use while doing some traveling. (In some areas, it works a lot better than I expected.) The problem is that fairly frequently, the connection drops and I can't reconnect. When reselecting the device (or any other network) in the list of available wifi networks, I get an error message that reads "failed to connect to network." My only recourse is to reboot. A fast reboot is good enough, but I've done plenty of those and complete reboots.
Then, I can reconnect. That new connection may last ten minutes or many hours. But at some point, the connection will drop and I'll have to reboot to get another one.
I figured this must be related to the Virgin hardware, but when I got home yesterday, I discovered that this happened again with my router. In the 5 months I've had the Nexus 7, I've never had a problem connecting to my home router. So I "forgot" my remembered wifi networks and reestablished them. There are only two, my home router and the Virgin device. Didn't help. Right now, I don't have the Virgin device turned on, so maybe this will temporarily solve the problem. I'm not sure, yet.
One thing that seemed to help was that when driving and using the Google Navigation app, this seemed to be less of an issue. It's even possible that we never dropped a connection while navigation was active. When nav is active, the device doesn't sleep. So there may be some relation there. But plenty of connections were dropped while nav was off and the device was awake. In fact, most drops occur when I'm stationary, i.e., not in a moving car or walking around.
Another piece of info — our other Nexus 7, which also came along on the trip, doesn't seem to have this problem, but it didn't get used that much, so it may be that it would be there, we just didn't have the opportunity to see it happen.
Anyone seen anything like this and/or have any ideas about what to do about it? Why would I need to reboot to renew a connection?
I had a similar issue,it would see connections not connect automaticly and when trying to manually connect it would disappear.I shut off the autoscan for networks off and it works much better.
Hope this helps

Thanks. I'll play with that and see what happens.
The nexus 7 that I purchased for my wife last week is experiencing the similar issue. I can see many network in range but any connect I try to connect will return a message "failed to connect to network".
I found some submitted issues on the Android project thread, but none of them offered any solution.

I'll try this at some other places to make sure the problem persists and will probably return it.

horrible WiFi strength ruining Nexus 10

Can anyone confirm or not if the crap WiFi strength on nexus 10s is an acknowledged fact? I have seen some say it is, yet still see other comments praising the devices WiFi saying it is stronger than ipones etc.
This is my second N10, I sent the first back due to WiFi performance and I believed it to be defective. My second devices arrival has suggested otherwise as I have noticed no improvement.... Am I just really unlucky?
On my home network, every other device has ho WiFi issues, but my n10 struggles! It seems to sho a decent signal strength in the WiFilist in settings, but a low strength in the top right corner.... Can anyone advise? I get similar strength issues on other networks (public and at friends houses. SO frustrating not being able to perform one of the most basic functions on a £300+ device). Was hoping 4.3/4 upgrades would help- nothing.
Should I get a third nexus sent out? Is this down to poor quality components? Anyone having same issues?
Thanks!
Hard to generalize, but mine has been rock-solid (on 4.3; I'm holding off on "upgrading" to 4.4). Seems to give faster throughput than my N7
My N10 seems to be at par or a bit better than my better halfs Ipad. Taking both tablets and going for a walk out in back (acreage), in the outbuildings, and near fences, the signal strength and ability to connect to my router and see other routers was actually a touch better with the N10.
When first getting the N10, it did seem to drop the wifi signal, but replacing the el cheapo several year old router with a newer medium price router cured that issue.
The Google Nexus 10 as well as the Amazon Kindle HDX are two of the few devices that actually support MIMO (multiple input multiple output) wireless.
This typically allows for very solid and swift wireless performance.
I suspect that software updates may have had some impact on the Wireless functionality of the Nexus 10, but that is also in combination with some types of access points, so it varies to each customer.
Some places I get really terrible wireless, but at both my work and at home, it performs extremely well.
Hopefully a future KitKat patch will address the wireless more. I notice that new binaries are included in KitKat pertaining to both wireless and Bluetooth for the N10.
Hello, I just became an owner of a Nexus 10. when I first time connect to my BSNL Teracom wifi router it is not connected. it is always showing connecting or obtaining IP address...
It connected through my S3 Hotspot but not through teracom router
I wake up in the morning and just press again the connect button. Bingo...it is connected..!!! Not understand why it is behaving like this. I am not done any changes in routers settings also. Is it not connecting b'coz the routers frequency mismatch or anything else ?? After once I switch off and on the router the same problem happens
all my phones including a Samsung s3, tab neo and also my laptop all are switches automatically connected to the wifi router.
Please help.
thanks in advance.

Yup... Crap WiFi on my nexus 10 too. Just randomly disconnects or is so slow that its unusable for streaming movies... I own a ton of android devices and this is the only one that gives me problems. When I turn it on, I just hope it stays connected. Let's hope this post goes through lol

Mine pulls 40mb out of a n wifi connection.. the main connection is only 50 -55 on average. I'd say its the best performing wifi device I own.
I have owned my N10 for over a year. The WIFI signal strength is good, but I often get some lag issues, which ended up being my router. When I have issues, I now reset my modem and everything works again. I have read that some people only have a 2.4GHz modem, and they have received better luck by limiting WIFI to that frequency only.
