There's a problem with WiFi in 4.2.1 that is not device specific I see people posting the same issue across many devices

i had some mysterious wifi issues too which disappeared 3 days ago...

i can definitely confirm that your description is probable
[Nexus 10 Q&A, Help & Troubleshooting] ga9213:
Thank you for testing the same scenario. I'd be sitting right next to my router to get -30 unfortunately, which is 3 floors below where my primary location is. Do you have a 16gb or 32gb version? I would be curious to know if there are potentially issues with batches of these devices and perhaps Walmart got a string of bad batches.

My skepticism with interference stems from the two tablets dropping at different times. If there was interference Tablet A and B would both drop simultaneously as they on the same SSID, same channel. Interference would impact both the same.

I'm a Software Solution Architect with a BS in Information Systems, so I know my way around a home networking setup. Firmware was updated to 1.0.07 which is the latest and was reset. I've attempted connecting via 5ghz only and 2.4ghz separately. I've had channels set to auto, as well as specified which channels as well as the channel width at 40 for 5ghz and 20 for 2.4. Again, doesn't make a difference.

However what's odd is my Internet TV which is in the same location upstairs shows much stronger 5ghz signal than 2.4. 3 bars vs. 2. The tablet shows 2-3 though when getting good signal for 2.4ghz and only 1 or zero bars for 5ghz...so it's the opposite as the TV.

According to the Google rep I spoke on the phone with when troubleshooting, he said he was aware of a problem with the 4.2+ devices with regards to wifi connection looping, but he wasn't aware of a signal drop issue, so there is at least one known wifi issue on 4.2+ devices at Google.

I'm not expecting people to help me here...because I don't believe there's any help they can provide other than confirming or denying the same issue. There IS an issue with these 3 devices. I owned a TF201 and a TF700t prior to this Tablet. Even with the TF201's abysmal wifi, it still stayed connected to the network in this location. The TF700t was pulling -55 to -60 dbm in this location with consistently solid performance, so it's quite reasonable to come to the conclusion that the N10's have wifi problems when no other devices do on my network.

I am going to wait to see what CES 2013 news is brought to market. If Tegra 4 devices are announced and seem as promising as I'm expecting, I will likely be abandoning my dreams of getting this N10 to work. I'm extremely disappointed that this is the experience I can expect from such a flagship Nexus device. If this is Google's answer to the ipad, it's a poor one.

I had issues with an extender as well. RE1000. All my android devices had problems with the extenders...for some reason it would drop the stronger extenders signal and pull from the router's instead. I couldn't figure out why and the constant jumps between extender and router caused hiccups when browsing so I just pulled it off the network.

There are a couple other networks within range but to rule out their interference I tested by manually setting the channels as well as tested in Auto.

I have had the exact same issues since I have had my N10. I think people who have not hand any connectivity issues are among the lucky few. Waiting for the next update to hopefully fix it. If not, I am probably going to be returning mine.
[Nexus 10 Q&A, Help & Troubleshooting] brGabriel:
This was the initial point I was trying to make. JellyBean 4.2.1 apparently does have a WiFi bug that affects some users

across many devices

, so the Nexus 10 alone is not to blame. That's why I suggested checking ROMs compiled from the latest AOSP source, as well as CM10.1 for a potential fix

until

an official update is released. What more is there to discuss?

You don't happen to be running AdBlock Plus, are you? I discovered it was causing constant WiFi drops on my N10. Uninstalled and replaced with AdAway, and no drops since.
[Nexus 10 Q&A, Help & Troubleshooting] ga9213:
No, it does it on a factory fresh ROM with nothing but 4.2.1 and the network system info app installed.
[Nexus 10 Q&A, Help & Troubleshooting] jonstrong:
I settled down to a spot in my house with about -65 to -72 signal strength and ran network info for 15 minutes. My Nexus 10 is unlocked and rooted but is stock 4.2.1 otherwise. Over the 15minute test I never saw signal strength degradation.

[Nexus 10 Q&A, Help & Troubleshooting] gdeadfan:
From my experience, I would guess that's router-related. When I first got my N10, I could not get it to hold a good wifi signal at my dad's house; I experienced the same signal dropping and failure to authenticate. However once getting back to my own house, I have not seen the issue again.
[Nexus 10 Q&A, Help & Troubleshooting] Elitevaz:
My wifi will cut out on the Nexus 10 randomly. One time it was really bad, but usually it resolves itself. I don't get problems with operation, sometimes a web page will take longer to load and I will notice all the wifi bars are gone.
[Nexus 10 Q&A, Help & Troubleshooting] NIK516:
The only time I get WiFi drops is when the tablet freezes then reboots my WiFi would just loop until I turn Wi-Fi on and off, I have also heard that this is a jelly bean issue, I'm also waiting on a update

i dont have problems with the wifi dropping maybe it is because of some channels of wifi that are very crowded on 5GHZ i have always a stable connection on 2.4 sometimes drops but thats because there are too many 2.4GHZ devices and routers in this neighbourhood

lots of people are reporting poor wifi on nexus10, 7 & 4. especially since the 4.2.1 update.. just check this thread on google.. http://code.google.com/p/android/issues/detail?id=40065
[Nexus 10 Q&A, Help & Troubleshooting] gordec:
I think we can all agree that there is something wrong with the wifi on N10, at least on a significant number of devices. Because a modern device like this is suppose to establish a robust connection to any router, period. I just got it and have experienced some small hang ups here and there. It shouldn't happen because I have had like 30 wifi smartphone, tablets, laptops come through my house never had any random disconnection issues. I hope Google/Samsung can give a firm answer to this issue.
[Nexus 10 Q&A, Help & Troubleshooting] drewskee:
I didnt read everyones post so not sure if this was done yet but perhaps the "WiFi- Optimization" under wifi, settings, advanced bieng enabled is causing this. I just disabled mine on the n10 and im outside on my patio to see if i get drops
[Nexus 10 Q&A, Help & Troubleshooting] wireroid:
Same problem across several RMAs. I thought it was a hardware issue at first, but after going through several different units and even changing the router (old one was dying anyway), 5 GHz drops incredibly quickly and 2.4 GHz does occasionally.

It's a shame, my original tablet had nearly unnoticeable light bleed and zero build quality issues. Now I have one with slightly worse bleed and creakiness, with the same Wi-Fi problem. :(
[Nexus 10 Q&A, Help & Troubleshooting] jodvova:
I have been having Nexus10 for 4 weeks already and I can confirm I started to see the issue the topic's author saw.

I have ASUS RT-N66U router. Its all has been working fine until a few days ago, when Nexus 10 started to suddenly drop wifi connection.

It does reconnect after 5-10 seconds and obtains IP immediately (no loop there).

I didn't try to pin it to a specific wifi-frequency, it is set to Auto.

What I tried to do is disable Wi-Fi optimization and it seems to make it more stable. I didn't have a wifi drop for a single day.

Wifi router is in about 20-30 meters of clear sight from Nexus 10. I didn't measure the signal level on the tablet when the drop happens though :(
[Nexus 10 Q&A, Help & Troubleshooting] scoppola:
I have had really annoying WiFi issues since day one (ordered launch day). Half the time I turned it on, the Wi-Fi icon would have no bars and I would have to toggle WiFi. Some apps that use WiFi would be very slow or unable to connect even when the browser was working fine (Sonos for example). I tried all the useless advice from the forums ... changing frequencies, turning off WiFi optimization, etc.

My Galaxy Nexus, Tab 10.1, and several laptops have all worked fine with my E2500, but yesterday I decide to try hard resetting the router. Then I decided if I'm going to bother with that, I might as well install dd-wrt while I'm at it

It's been less than 24 hours, but I'm prepared to say WOW! No signal drops, and Sonos connects instantly (which it has NEVER done before with the N10).

After flashing dd-wrt, I discovered that it doesn't support 5ghz mode on the E2500. Next up is to try Tomato, which apparently does.

Of course, I'm not sure if it was the hard reset, or the dd-wrt that worked the magic.
[Nexus 10 Q&A, Help & Troubleshooting] sameer1807:
i think the wifi problem is iminent due to a problem between both the router and the N10. at first, i connected to my DIR-825 router and when i went 1 floor down, it would drop, wifi would run slow and so on. but when i switched to my verizon router, all around the house i was getting stable wifi, it never disconnected and worked fine. i havent figured out what setting to change on my dlink since N10 is out on warranty repair lol.

I'm also having this issue with my N10. Makes my tablet almost completely unusable at work. But have had it on 2 other devices running Jelly Bean (not just 4.2) as well. I don't think it's a device specific issue like others have said, but instead an OS issue.

Considering how badly the Receiving departments in most Walmart stores handle electronics during truck unloads, it's easy to get defective/broken devices there.

wifi issues

I'm having the same issue with the WiFi. I have to switch it off and back on before it works properly.
[Nexus 10 Q&A, Help & Troubleshooting] AztlanUnderground:
After working flawlessly for weeks, wifi started to crap about one week ago and it's been hell ever since. Started with occasional disconnects and gradually got worse to the point where it would not hold a connection for more than a few seconds as soon as there's some wifi traffic now. Given the way google designed this tablet, wifi is critical and my N10, which i liked a lot while it was functional and despite some of it's shortcomings is now pretty much a useless piece of crap. The only thing i'd wan't to do with that crappy N10 now would be to slap Eric Schmidt in the face.
[Nexus 10 Q&A, Help & Troubleshooting] Kevin K:
I has to do with the 4.2.1 update. My Nexus 7 worked great with no drops before the update. Now it cant find or drops. Google needs to figure this out.
[Nexus 10 Q&A, Help & Troubleshooting] w1_m2:
wifi drop here also

My N-10 drops all the time. I keep my N-10 on a table next to me when I am using my desktop. Every now and then I hear it reboot. It is not touched in any way. It's like an Android.:eek:

It has never bothered me much although this should never happen. Why? Because it takes less than 10 seconds to reset which makes it bearable.

I have an Airlink 101 router which has been flawless for years. Also note that when I am on my desktop I am on my wireless router. My desktop never loses the connection even though they are a couple feet apart. I use wifi N only. I use wpa-psk, aes. So, there are my clues. Oh, and I am never more than <12 feet away from my router.

I was able to stabilize the wifi connection with my RT-N66U. I changed the channel frequency from 20/40Mhz Auto to fix 20Mhz in the 2,4Ghz band.

[Nexus 10 Q&A, Help & Troubleshooting] LucidChaos:
Definite wifi problems w/ 4.2.1 for me as well. Tested on (2) Nex10s, across 3 different routers trying various configurations and radios. The workaround for me seems to be using a 20mhz channel bandwidth on the wireless radio as opposed to 40mhz. No drops for me as over the first 24 hour period running on 2.4Ghz with a 20 Mhz channel bandwidth. Wifi connectivity is finally stable! This is the most consistent its been since getting it so my hopes are up.

[Nexus 10 Q&A, Help & Troubleshooting] tirantloblanc:
We already have a similar thread in Q&A. I would like to add that nexus works perfectly in 40MHz with WPA disabled. WPA with tkip is also OK. The main problem comes when using WPA with AES.

And even if the nexus 10 didn't support 40MHz, it should negotiate it with the router. I have tons of old devices that don't support 40Mhz and they still work fine.

In my case when I disable 40MHz, it stops disconnecting, but WiFi is still quite slow sometimes.
[Nexus 10 Q&A, Help & Troubleshooting] RobRoy:
Hi,

Just to be sure. Do you use WPA or WPA2 with AES?

To be sure set router to WPA2 only AND AES only.

Mixed modes confuse the poor tablet easily, doesnt seem to take a lot.

Cheers
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
Well if that would be the one thing to solve my problem then I guess Im screwed. I dont want to use an open network or the easily cracked WEP. And since my router only will work with AES encryption I dont have a choice to use anything else.
[Nexus 10 Q&A, Help & Troubleshooting] tirantloblanc:
Yes, I was forcing AES.

WPA/WPA2:

TKIP: Working

TKIP/AES: Not Working

AES: Not Working

I have to say that after flashing Franco's kernel with the new google drivers, it seems to work better. But it's still not acceptable. No more disconnections with my home router, but I'm still unable to watch full videos in streaming (music videos of 4minutes are still a no). At work, it seems to connect to the router and get an IP, but nothing else.

I already called google, and they will be sending me a new tablet in a couple of days. Let's see if it's hardware related or not.
[Nexus 10 Q&A, Help & Troubleshooting] RobRoy:
Does your router have a way to setWPA2 only not WPA/WPA2?

That seems to confuse again soime routers.

This is def a software issue... I had the problem where my WiFi on my nexus 10 was only downloading at 1mb instead of 10mb. No matter what protection I used.

[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
Not all routers will allow TKIP with Wireless N, actually none should. IF yours does then that just goes to show why some routers work and some dont. No one follows proper standards when designing these things. The Wireless N standard is not specced to work with TKIP and is only allowed to use AES.

I have exactly the same issue with my N10. And I've tried it with 4!!! wifi sources:

- Fonera 2.0N

- Asus AC66U

- TpLink TL-WA854RE Repeater

- TpLink TL-WA801ND Access Point

With the last one when I'm lucky I get a 130Mbps connection. But then, when I start streaming a movie from my NAS, the connection drops to 24Mbps and the I cannot watch the movie anymore. This is 5m from the Access point with 2 brick walls in between. If I look at the signal I see that it drops and then again good and so on.

With my Nexus5, S3, Laptop, and the cheap Galaxy Pocket I have had absolutely no problem with any of the wifi sources. For example, when the connection on the Nexus10 becomes so unstable, I quit and I continue watching the movie on my Nexus5 without any problem.
