[Nexus 10 Q&A, Help & Troubleshooting] Nitemare3219:
I disagree. It's definitely something to do with 4.2. My Galaxy Nexus had zero problems holding a WiFi connection near the edges of my home, however my two new devices somehow do? My Nexus 10 is much better about keeping and using WiFi than my Nexus 4 is, but there are times where it drops connection way too close to the router and takes a lot longer than it should to recognize the signal again.
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
Are you talking about a dropped connection from low signal, or a complete disconnect that looks like the radio has turned off and then back on even when bars are full? Two very different issues

If you go into the same room as your router and have full bars, does the signal suddenly drop completely and then reconnect to the same network? If it does, then you are talking about the seam issue I am. If you don't have that problem and only get it when you have 1 bar of wifi then you are talking about a completely different issue.
[Nexus 10 Q&A, Help & Troubleshooting] Blueback22:
Mine is the same issue as yours. Wifi radio appears to turn off then on again.
[Nexus 10 Q&A, Help & Troubleshooting] GAH1068:
I have also observed the same results. I can also confirm that all other wifi devices will occasionally get knocked off when the wifi dropout occurs.
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
What brand of router are both of you on? Perhaps we can narrow it down to a manufacturer.
[Nexus 10 Q&A, Help & Troubleshooting] Blueback22:
Belkin. Switching to a Netgear tonight.
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
Hmm, alright. Well Im on Linksys so I guess that idea goes out the window.

Try your router in completely default settings to see if wifi works. Whether it does or not, make note of it and then go about changing your settings one at a time and testing the wifi to see if it ever does/does not have an issue and what setting affected the stability
[Nexus 10 Q&A, Help & Troubleshooting] Blueback22:
Netgear router was a bust. Same issues right off the bat.

It seems on my Belkin I can run this tablet on the 5ghz network and be OK (it's by itself on that band). If I put it on 2.4ghz, I have major issues.
[Nexus 10 Q&A, Help & Troubleshooting] Blueback22:
Called Google. The seem to think it's a device issue. I've for the most part narrowed it down to a bad 2.4ghz radio and Google agrees. Warranty replacement coming my way.
[Nexus 10 Q&A, Help & Troubleshooting] Droid_Junky:
I completely agree with what you suggest. I had similar issues a few months ago with a Linksys router. I could not get all devices online at the same time. Imac continously dropped connection as well as my Galaxy Nexus. Removed all security settings and all devices connected fine. No drops. Ended up splitting devices between 2.4 and 5ghz with both wpa and wep security. It was the only way to stop everything from dropping out.
[Nexus 10 Q&A, Help & Troubleshooting] Blueback22:
I tried this with the new Netgear. It was actually worse.
[Nexus 10 Q&A, Help & Troubleshooting] wireroid:
I have the same problem. The WiFi chip seems to randomly shut off, especially when I'm running WiFi Analyzer. Sometimes it turns off entirely and I have to force a reset to get it to connect again. A regular power-off/power-on doesn't fix it.

Also, if anyone else has WiFi Analyzer installed, does the backlight also flicker for you when it's scanning for networks? I have a feeling that there's interference going on between the WiFi chip and whatever drives the display...
[Nexus 10 Q&A, Help & Troubleshooting] Blueback22:
Google recommended factory reset. If that doesnt fix it, then get a warranty replacement.
[Nexus 10 Q&A, Help & Troubleshooting] Matthileo:
I don't have signal issues but I do get flicker in WiFi analyzer on the signal strength by channel graph.

Same here.
[Nexus 10 Q&A, Help & Troubleshooting] zero383:
No WiFi issues here either. Using a Unifi AP as an access point. Getting 3 out of 4 bars from the other side of the house. I have it set to a static channel, 802.11n only, WPA2/AES, HT40 mode. The N10 has about twice the range as my Nexus S which is known for it's weak antenna.

It looks like WiFi Analyzer needs an update for JB 4.2. I'm getting flicker too and it shows my AP twice (once with the name of the SSID and another entry with "?"). This does not happen on my Nexus S on 4.1.2.

[Nexus 10 Q&A, Help & Troubleshooting] bioorganic:
This got me curious, so I did some digging. Linksys switched from Broadcom to Marvell for the V2. I'm using a Netgear WNDR3800, with an Atheros chip, running DD-WRT. I've had zero connectivity issues with the Nexus 10 at 2.4 ghz, which is very very crowded where I live. 5 ghz is completely empty, but I can't maintain a connection at the lower end of the spectrum. On channel 153 or 157 I have no issues. If you follow router firmware development, there's endless discussion about the issues with different chips and firmware combinations. I definitely agree with your conclusion.
[Nexus 10 Q&A, Help & Troubleshooting] risktaker:
Signal strength is very week on 5Ghz 802.11n and I do get random drops every 2 minutes. Anybody see the same issue? Range is about 10-15m from AP.

Ive had the same thing with wifi dropouts. Tryed on AOSP and ParanoidAndroid rom, couldnt keep a connection for 5 minutes. Flashed the CM10 manta nightly, and its been working fine for the past couple hours.
[Nexus 10 Q&A, Help & Troubleshooting] TheWenger:
I don't get random wifi drops while using the tablet. But if I set it down and don't use it for about an hour or more, it seems like the wifi just cuts off and gets stuck on authenticating.

Random Wifi Issues

I too have experienced random wifi issues. I just got a N10 & updated to 4.2.1 and sometimes it seems like the Wifi just drops (even though the wifi icon still says it's connected), and i have to turn the wifi switch off/on. But when i turn it back on, it just sits at "turning wi-fi on..." for a little bit and then eventually connects back. All the Wifi settings are at default (band is set to Auto).

This only happens randomly - sometimes it stays connected just fine.

Should I try a Factory Reset? or?

Im experiencing the same thing only at work tho really wierd seems to be a everyday thing tho
[Nexus 10 Q&A, Help & Troubleshooting] TomAshcroft:
This is also happening to me but it doesn't happen on my HTC sensation just my nexus 10. I'm sure not everyone experiencing this thinks its down to the router as I was fairly certain it was the 4.2.1, are you guys saying this is not the case? I had mine tethered to my phone and it was still drooping WiFi.

Suggestions ? Return?
[Nexus 10 Q&A, Help & Troubleshooting] Matthileo:
I think it's a combination of both. On my at&t router everything is fine with my Nexus 10 no problems whatsoever. On my mother's Linksys router however, my tablet was experiencing considerable WiFi issues. When I disable the 5 gigahertz band, everything was fine and I could use my tablet on my mother's wireless router.

[Nexus 10 Q&A, Help & Troubleshooting] Blueback22:
ATTENTION! HERE IS THE FIX!

Here is what I did and Google concurred.

1) Go to BestBuy and pick up a new router (different brand than current). Set it up. Still having issues? It's not the router, return it and get money back.

2) Factory reset device. If still having issues it's a device issue.

3) Call Google and RMA device.

(It's not Android 4.2 or 4.2.1)

My new device is working PERFECTLY. I tried every setting on my router and my device. The only stopgap fix was to run my device on 5Ghz. It didn't like 2.4Ghz and screwed every other device on the network up while connected.
[Nexus 10 Q&A, Help & Troubleshooting] TomAshcroft:
Hmmm I guess that's what I have to do then. Will need to unroot :/
[Nexus 10 Q&A, Help & Troubleshooting] TomAshcroft:
I am returning mine for a replacement. Question is, how do you *know* its not 4.2 or 4.2.1? Just curious.
[Nexus 10 Q&A, Help & Troubleshooting] lKBZl:
Settings - info about phone - scroll to the bottom and check if it says 4.2 or 4.2.1
[Nexus 10 Q&A, Help & Troubleshooting] TomAshcroft:
Oh no what I mean is, whether 4.2 or 4.2.1 is the problem for the WIFI stability. How blueblack knows this, just wondering whether first batch of n10's are faulty maybe.
[Nexus 10 Q&A, Help & Troubleshooting] Blueback22:
Because I tested my new device on both versions without issue.

Only change in 4.2.1 is the "December fix".
[Nexus 10 Q&A, Help & Troubleshooting] TomAshcroft:
Ohhh right so its this batch of n10s? It seems a factory reset has fixed it for me
[Nexus 10 Q&A, Help & Troubleshooting] Blueback22:
You got lucky. I wish I didn't have to RMA mine, but I did and I'm good now.

I dont know if it's that batch or just bad QC, but I know I (and others) tried EVERYTHING else before using the RMA option.
[Nexus 10 Q&A, Help & Troubleshooting] cds36:
In my case I do think it's a router issue as it only happens at work not at home
[Nexus 10 Q&A, Help & Troubleshooting] TomAshcroft:
Yeah I've already sent for a return though , so just in case I'll be getting a new one

Edit: after five hours usage, had to switch WiFi on and off to continue browsing, looks like I'm getting the connection drop again. Good news I'm being sent a new one I guess

When you send for a return is there any downtime without it?
[Nexus 10 Q&A, Help & Troubleshooting] Blueback22:
No. They put a hold on your card for a new device, ship you the replacement, and you have 21 days to return the original. Shouldn't take 21 days to get the replacement.
[Nexus 10 Q&A, Help & Troubleshooting] jackpetrilli:
I would say definitely a n10 problem. I've had no wifi issues here running 4.21, trying 2 different routers at both 2.4 and 5g. My signal is always at least 4 bars, wherever I am in my house.

I wouldn't take the chance, just have Google replace your Nexus.
[Nexus 10 Q&A, Help & Troubleshooting] cds36:
If it was a n10 problem I think it would also happen at home also not just work? It also does it with my galaxy Nexus 4.2.1 same issue at work but solid at home

For what it's worth, I spoke with Google customer support yesterday, and they said another software update would be out in about a week that could possibly address the wi-fi stability issue. Granted, this is from their front line support and there's a lot of "maybes" there, but I thought I'd pass it along.

If this holds up, I may have discovered the cause of my constant wifi drops. I'm rooted and running AdBlock Plus. On a whim I uninstalled AdBlock Plus and replaced it with AdAway. Haven't had a drop in over 8 hours now, where it used to be dropping every few minutes.

[Nexus 10 Q&A, Help & Troubleshooting] orangetag001:
I'm having the same problem as most others here as well. When I try to connect to my home network it just sits there for quite some time just authenticating over and over and over again. Nothing seems to change that either. I never had this problem until I went to 4.2.1. I've tried changing the advanced settings and nothing in there seemed to affect it. Also if I do eventually get on to it and I go to browse it won't be long until I go back to constant authenticating.

I know this doesn't really answer any questions but I'm just going to RMA it. Good luck to all of you out there.

On my 4.2.1 stock, non-rooted, locked boot loader, N10 I have been getting random WiFi drops. I tether to my Evo3d (Sprint hotspot). I have noticed that many times when the drop happens the WiFi icon shows connected, but gray, unlike when it is really connected and the icon is blue. When this happens I check my phone to confirm, it shows no connected users, then I check the N10 it shows connected (again gray icon), at which point I attempt to shut off the WiFi connection from the tab, at which point it hangs. I back out of settings, and go back in and try to turn it on, again it hangs, forcing me to reboot. Once rebooted it connects with no problem and I go about my time. I have yet to see a pattern that causes the drops, I've gone days to a matter of minutes when this has occurred.

This is my second N10. Took back the first due to poor wifi, the second has the same problem. If it's hardware and not software related, it's either a poor design, or a lot of bad tablets.

I sold a TF700t to buy the N10 and the wifi capabilities aren't even in the same ballpark. At the point in my house furthest from the router I get acceptable signal on all my wireless devices (Internet TV, My cell phone, wife's cell phone, TF700t, Laptop, etc) yet this tablet won't stay connected there. Terrible signal reception and it will drop the connection and then go into an endless loop of obtaining IP and then authorizing even after I get back to good signal.

My razr MAXX gets good reception pretty much across the board at this location but the Nexus is all over the place. Good reception for a few seconds here and there but then back to terrible.

-80 dbm on the N10, -65 on the Razr Maxx. Terrible, simply terrible.

[Nexus 10 Q&A, Help & Troubleshooting] RobRoy:
Hi,

If you have a 300 or 450 router best set it to 20 MHz channel on the 2.4 GHz band..

N10 only suports 20MHz 2x2 on 2.4 GHz and 40Mhz 2x2 for 5Ghz.

There are reports that having a 300/450 router running auto20/40 or 40 Mhz fixed for 2.4 Ghz causes issues for the N10.

Also suggest to turn off Wifi Optimisations.

Let us know how you go.

I get drops outs ever 5-10 seconds usually, I usually have 2-4 bars of signal, Good to Excellent, but it will either make the bars go grey sometimes black (completely gone) then comes back.

I also have the brightness bug, it keeps jumping around with the auto brightness, even when the light hasn't changed or tablet moved...

Anyway I've tried all the suggestions on the internet, none worked...

I anyway I turned the auto brightness off and guess what, wifi has not cut out, although it does now read a very low signal, but i've gone 20 mins and not one cut out...

But I'm concerned about the low signal, I'm only sitting 12ft from the router...So the cutting out bug seems to be fixed, but if I go any further away I won't have any signal anyway...

I also have a Nexus 4, and if I have animations turned off, the brightness bug (a different one comes, you cannot adjust brightness)

I have a HTC Sensation and HTC Desire HD, both had super excellent wifi signals on ICS, I rooted and installed 4.2 & 4.12 and the wifi signals are weak, not continuously cutting out, but only have a range of 5-8ft.

I also have a cheapo Chinese tablet with wifi range of only 10ft using 4.12

I have Netgear WNR3500 Router also I have Heuwei E586 mobile broadband, I get the exact same problems with both, so I doubt it's router related...

It does seem to be Jelly bean problem, not just 4.2, but also 4.12...

But my friends got Nexus 10's and none of them have wifi issues...

My N10 also freezes/black screen and requires holding power down to turn off.

It's really disappointing for the best tablet in the world to have such major problems...

I waited 2 months for this, due to no stock, Google really needs to do better, it's not it's being run by a man in a shed in China...
