[Nexus 10 Q&A, Help & Troubleshooting] samaraki:
I don't think it's a router issue, because I get the same problem with my Huawei E586 mifi dongle. Also I took my tabby to tesco's and got the same problem using the Tescos in store wifi...

It's definitely firmware (Nexus 10 version, cause it's fine on Nexus 4) or hardware.

I think Google are so easy on these returns is because they're just repackaging them and sending them out again...

My friend got his and it was already opened and mine it was sealed but the box was dated 05/12/12, considering they've been out of stock and back in 2-3x since then, my batch should of had a much newer date, like say 20/01/13 or something. (It came with 4.2 and not 4.2.1).

Which means it's an older tablet, but they said they was out of stock, so why would there be any old ones about, unless it was a return. I ordered as soon as they came in stock a few days ago, so seems to me they don't really have stock, they just repackaged all the returned December models.

All this talk about turning the optimization off, turning off frequencies off, setting a fixed channel number, etc etc it's nonsense, it does nothing.

It's either faulty hardware or firmware.

Why don't Google keep us informed in what they're fixing? They'd save themselves a lot of hassle with returns and keep their customers happy...

Why don't they test the products before shipping? The crashing and wifi problem isn't exactly hard to find, I noticed the wifi problem within literally 30 seconds of first connecting and it crashed after only 20 mins...

It must be a router issue for me as it only happens with the router at work ...at home its fine rock solid dunno.
[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
How would I change this
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
Either by init.d script, or by setting them through an app such as system tuner. I was just thinking that making the buffers for data larger might help some stability. I cant be sure unless more people confirm, but ever since I set mine to these settings I havent had nearly as many random disconnects from wifi. It could be some other change that happened around the same time though so I cant say for sure that those are what helped me so much. Either way, allowing more data to be buffered should increase speed and lower system I/O. We have 2GB of RAM so Im sure we can spare 2MB for the buffers
[Nexus 10 Q&A, Help & Troubleshooting] tirantloblanc:
It's definitely a tablet issue. I don't know yet if it's hardware or software related. I'm thinking it could be hardware related, otherwise it would happen to everyone. It could be that some tablets include a faulty revision of the WiFi chip.
[Nexus 10 Q&A, Help & Troubleshooting] Blodgrape:
I have had my N10 for a week now and I've had big issues with my unit disconnecting etc. Strength goes up and down when connected. When I found this topic I tried some of the suggested solutions but it har really just given me some marginal improvements. All my other wifi connected units have all run rock solid (100%). Last days running it stock unlocked and rooted. I guess I don't have to say it's annoying as hell.

I'd like to try out this solution with making buffer size bigger. Anything is worth trying but I'm not sure how to go about doing this using init.d script. (while writing this I dropped connection once). If you have the possibility please post a step by step tutorial. Now I'll download system tuner and try to see if I'll manage to do it with that app.

Thanks!

Update: My defaults settings on rmem.max etc are 0.12MB changed to 1MB now through System Tuner app. Now let's se how it goes.
[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
I guess its working a little better but now how it should... My galaxy nexus running 4.2.1 is getting speeds up to 10mb down as well as my iMac, Macbook pro, iPad, iPod touch. While my nexus 10 is getting close to 1.5mb down :confused:
[Nexus 10 Q&A, Help & Troubleshooting] Blodgrape:
Seems I get better speeds and connection with TKIP (I disabled AES on my router).
[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
Lol this s*** sucks my I ternet at work is horrible and I'm getting speeds 3 times faster there than I get at home. It works perfect at both my jobs routers
[Nexus 10 Q&A, Help & Troubleshooting] tirantloblanc:
My main concern when disabling AES is that some advanced options are also disabled (you may lose some speed). Well, that's according to IEEE 802.11n specification, but not all routers comply with the standard.
[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
So the people not having issues, what router are you using. I'm getting rid of mine I can't deal with this. I had a issue with WiFi dropping out on android 3.2 on my Acer a500 with this router but not on my work one either so I'm just going to get a better one.
[Nexus 10 Q&A, Help & Troubleshooting] tirantloblanc:
That's an interesting question.

Or they are using a router without the 40MHz option enabled or the WiFi in their Nexus 10 is working correctly.
[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
Mine has 40/20 and 20 I tried both and get the same results
[Nexus 10 Q&A, Help & Troubleshooting] tirantloblanc:
I have been testing the new Franco Kernel.

This kernel includes the latest official WiFi drivers from Google/Samsung. Reception seems better. I don't get disconnections, and my Nexus 10 tablet seems to associate correctly with an AP working with 40MHz and WPA2 AES, something that was impossible before.

BUT, even if it associates correctly (and gets an IP) there's no network access.

On other routers, even if the situation improved, it's still not perfect, as I'm not capable of seeing full youtube videos (3-4 minutes). There seems to be interruptions as before.

If you are suffering this problem with your Nexus 10, your best option is to call GOOGLE and ask for a replacement.

If I had enough free time, I would go further and start analyzing 802.11 packets to determine where the problem lies. But at the moment is not possible :(.
[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
I don't think this is a hardware issue though. There were similar issues with WiFi dropouts on honeycomb 3.2 and it to do with dhcp lease times. This isn't the same but it also affected only some wireless routers mine included. My nexus 10 works fine on my jobs wireless at 2 different locations. Just not mine at home. But what is also strange is that my galaxy nexus which is running the same version of cm10.1 as my nexus 10 doesn't have this issue. Lol ALSO when I first got my nexus 10 a week or 2 ago it was on 4.2 and I had no problems with WiFi at all. This started to happen after I updated to the latest version.
[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
OK I went out and got a new wireless router and everything is working normal. Just incase your curious to know it was a netgear wndr3700.
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
I am still of the opinion that it is entirely dependent on the combination of Nexus 10's wifi chip and the routers processor chip. Some just dont mix well.
[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
I would also believe that but I did not have this problem on 4.2. It started after the update. Are there any 4.2 ROMs I could test on? I'm going to check the dev section.
[Nexus 10 Q&A, Help & Troubleshooting] tirantloblanc:
You can flash the original Nexus 10 rom.

https://developers.google.com/android/nexus/images#mantaray

You will need to unlock the bootloader of the Nexus 10. Everything is easily done with android SDK.

I tried that ROM and couldnt find a difference with the 4.2.1
[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
Is that what it shipped with? I thought mine was another build number.
[Nexus 10 Q&A, Help & Troubleshooting] tirantloblanc:
It's the only one available from Google. But I'm not sure if its the one that shipped with every nexus10.
[Nexus 10 Q&A, Help & Troubleshooting] tirantloblanc:
Well, FINALLY I think I found a way to 'fix' the crappy WiFi!!! It's working amazingly well now, even at 40MHz. I will keep trying during the weekend to confirm it.

- Disable GPS location tracking

- Disable 5GHz band in WiFi settings ( select 2.4GHz only)

With those settings changed I can finally watch YouTube videos without any interruption!

[Nexus 10 Q&A, Help & Troubleshooting] droidroidz:
has anyone with issues tried one of the many good custom kernels, almost all of them have the latest additions from Google that will most likely be present in their next update.

[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
I have and still had the same exact problems.
[Nexus 10 Q&A, Help & Troubleshooting] rxzlmn:
I have problems with 802.x authenticated networks (PEAP/MSCHAPv2). Most of the time the N10 keeps trying to reconnect, without ever succeeding. Sometimes, rarely, the connection works as it should, but might also just revert to the re-connecting state after half an hour or so. I don't know what triggers it, as not even rebooting helps. Connecting to the same network that is distributed openly and login works via a website works flawlessly. I tried changing the bands but nothing helped. Both of these networks are reliable and sophisticated (one public nation-wide network, one university network). Anyone having these issues as well, or anyone not having any issues with 802.x networks?

Got my replacement tabby, took 9 days, and it's got the exact same wifi issue, ALSO this one has mega washed out screen, the first one had a great screen...

---------- Post added at 05:02 PM ---------- Previous post was at 05:00 PM ----------

I dunno why people think it's their router, I've treat Netgear, Tenga, Huawei & Belkin, at different houses too. All are fine on Nexus 4 and every other device I've ever had, it's just the Nexus 10...

The problem is on 4.2 as well, I just got replacement, it's the same on 4.2 and 4.2.1

on both Tabbys they sent me.

Doesn't work, tried and tested with 2x Nexus 10. This is old news...

You test with a bad app, Youtube will load most of the video long before it's finished playing, so if it's a 15 min video, most of it will be loaded within 1 min.. So even if you get cut off, it's already downloaded the video, try downloading a large file, or clicking links continuously for a better test...
[Nexus 10 Q&A, Help & Troubleshooting] stealthj:
I'm on my third replacement, 4th one on the way. I'm going to be keeping the next one cuz i really do productivity on my tablet and what not....

Wifi issue was present on all my devices no matter what kernel or mods or options ive changed such as wifi optimization or changing to use specific bands...

At work, at school, ( with SUPERFAST internet)... my nexus 10 still drops and reconnects every now and then and is really slow still..

I'm not sure what the hell is going on. google offered to refund me my money too but I want my nexus 10....

god damn headache...
[Nexus 10 Q&A, Help & Troubleshooting] Lloyd76Mongol:
The only thing that helped my wifi issues was clearing the data of chrome and installing chrome beta.
[Nexus 10 Q&A, Help & Troubleshooting] gmfeny:
Somebody should get a log of when WiFi dropsout
[Nexus 10 Q&A, Help & Troubleshooting] samaraki:
Just to let everyone know, the 4.2.2 doesn't fix the wifi problem on the Nexus 10.

I think someone needs to clarify the actual problem, so I will do it.

There actually seems to be people complaining about various ones.

There is one where the connection shows the signal, however the blue bars turn grey, this one happens less frequent, I get this 4-5x a day on my Nexus 4, it's no big deal and not sure why everyone is complaining about it so much, and I believe this is why people keep finding "fixes" because it can go sometimes several hours or days before screwing up... Of course they come to comment saying, clearing chrome cache fixed it, doing this fixed it, it was never fixed, but it just takes a long time to be reproduced...

I don't know if Google fixed this problem in 4.2.2 because my Nexus 4 has not had an update, but it's not a big deal.

The big Wifi problem is the one I face on my Nexus 10, the connection doesn't "grey out" It "blacks out" the instead of going blue to grey bars, it goes blue to no bars, it just shows the frame, show the empty background, The same as you get when you "newly" connect to a connection, before it's fully connected, this will happen every few seconds to every few mins, and makes the device unusable, this problem has not been fixed and seems to be more like a hardware fault, Because routers, settings, updates everything has been ruled out, and not everyone is getting the same problem, even though using the same routers... So it's got to be a hardware fault and this is probably why everyone is quiet on it now, as no doubt they've either returned their tablet for a refund or got a working replacement and didn't bother to keep anyone informed... (Happy customers don't complain, or update their complaint status, usually)
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
This has been the primary talking point of this thread so far. I also fixed mine with router settings as I sated in another similar thread (which I thought was this one). Also, this problem is what used to happen at my home, but not at work at all. They are similar routers, my home one is a Linksys E4200v1 and work is a Linksys E4200v2. Anyway, these are the settings I use no and I no longer have any wifi problems:

http://xdaforums.com/showpost.php?p=37834076&postcount=36

Also, this same wifi issue happens on my Nexus 10, Galaxy tab 2 7" (which runs Android 4.1 now and same problem when it used to run 4.0), and my Galaxy Nexus all throughout its 4.0 to 4.2, to 4.2 life. The issue is now fixed on all my current devices that previously had the alleged "hardware" problem.
[Nexus 10 Q&A, Help & Troubleshooting] unknown_owner:
Have any of you looked at the logs of your routers when you are disconnecting? I have had the disconnecting to my router whenever I do a reboot or start up from a power off. All my devices on my network lose wireless connection the moment I start up or reboot. I finally looked at my router logs and saw that whenever my N10 connected, the router would go through a wireless reset of both 2.4ghz and 5ghz connections. This cycle would happen for about 20-30 min. Mind you I'm resetting my tablet again and resetting my router over and over. This doesn't happen to any other of the 5-7 wireless devices I have on my network, even if I restart those items.

This happened to me today at home and 30 min later it was still losing connection. I have it on Auto (2.4 or 5) and WiFi optimization turned on. So i get to work and try my work network and it connects with no problem. I even changed it to work strictly on 5ghz and that is still running fine. No disconnects so far.

So is it my router, maybe its the first revision of the D-link 825 with a firmware from 2010. DD-WRT doesn't support this revision. Maybe it's time for a new router.

I'm going to reset to factory with the stock image and try it at home and see how that goes. Going to reset to factory while at work to make sure that still works first.

So for those lossing connections, try looking at your router logs to see if what's happening. You might find something there.
[Nexus 10 Q&A, Help & Troubleshooting] EniGmA1987:
^^^^^ I would go check my router logs, but as I fixed the issue I wont have any logs to see that there is a problem. And sorry but Id rather not purposely break my router with different settings just to see what a log file says. It took me long enough to get the settings right that I just dont want to touch it anymore.
[Nexus 10 Q&A, Help & Troubleshooting] unknown_owner:
With a factory reset, my tablet still worked on my work router. No disconnects at all. So at home, the minute I connected to my home wifi, my router wireless reset and knocked everyone off of wifi, both 2.4 and 5ghz. It kept doing this as I left it alone to see if it would connect on it's own, but it was stuck in a wireless reset loop. I changed my 5ghz channel width out of Auto 20/40mhz and set it static for 20Mhz. Rebooted my tablet and watched the router logs again and no wireless reset. All my wifi connections were solid with no interruptions. Then I changed the channel width to a static 40mhz and rebooted the N10 and still solid connections. Rebooted again now only the 5ghz band was stuck in a reset loop. All the devices in the 2.4 band kept their connections solid. So I have moved back down to the 20mhz channel width on the 5ghz and all is stable.

So is it a router or tablet issue? In my opinion I'd say both. Time to get a replacement N10 and look into a new router that can better handle this weird issues. My current router is a Dlink dir-825. I think I've had it for at least 4-5 yrs
[Nexus 10 Q&A, Help & Troubleshooting] mjpado:
Issues no more!!

Ok, I had MAJOR WiFi stability issues, it would drop at least 10-20 times a day with heavy use. This ALL changed when I upgraded from a d-link 300 to a Linksys dual band ae3500. Once I was able to dedicate to the 5ghz band, NOT ONCE has my WiFi dropped today. That is the difference, a good router is the solution to WiFi stability.
[AT&T Samsung Galaxy Note II] SpectrumOnFire:
Alright, so the unthinkable happened. Yes, I dropped my beloved Note II. Less than two weeks into owning it, too.

The drop was about 2 feet and landed on my foot, then bounced onto a tile floor (yeah, I know). The fall was light and hardly made a sound, but alas I now have a spiderweb originating on the left side of my screen. It's not too bad but here are some pictures so you know the kind of damage that can befall your phones.

It was VERY difficult to take pictures of, but it's easy to see under a light. I just thought some of you might want to know how easily the screen can be broken.

If anyone has any advice on dealing with this, It would be greatly appreciated.

P.S. I'm in Canada with Bell, and have their smartphone premium care plan. I haven't spoken to anyone yet as this happened this evening, but it looks like it only covers accidental damage resulting in failure, for which i have to pay 150$ for a new phone (that seems to be the only option). So for now I think I'm stuck with a very sadly broken screen. If anyone cares, I'll update later after I talk to them.
[AT&T Samsung Galaxy Note II] wallyg8r:
I have same plan with Bell. You will be covered. Just have to pay the $150 on your next bill and send in your old one. My daughter dropped a 3 week old bold 9900 into the toilet and it was covered!

If anyone has experience with repair options I'd love to hear about it.
[AT&T Samsung Galaxy Note II] 9wire:
I got mine on release day, and the guy in the store took their demonstrator to lunch and dropped it. Cracked the screen on the corner.
[AT&T Samsung Galaxy Note II] ezklr:
I replaced the screen on my Inspire and it wasn't too bad. I watched the video of replacing on the GN2 and it looked quite a bit easier, so I think you would be fine trying to replace yours. Good luck
[AT&T Samsung Galaxy Note II] sodomanaz:
Too funny. I did the same yesterday. Had it sitting on my wallet face down on the kitchen table and it slid. I caught it with my legs, rolled off my foot and hit the ground. About a 6 inch fall at most. Two big cracks and a chip. Two generations of notes, two broken screens Haha.

Have a square trade warranty and the phone actually functions like normal so there is at least that.

[AT&T Samsung Galaxy Note II] drochro:
I got the AT&T protection plan for just 10 bucks more, covers everything...... EVERYTHING!
[AT&T Samsung Galaxy Note II] SpectrumOnFire:
The problem is that I'm not sure if it's just the glass on the front that's broken, or the OLED/ touch panel itself (since I believe it is a single panel on this phone, right?), which is at minimum 200$ to order the part. I am entirely comfortable replacing it myself, though I don't want to pay that much if I can avoid it.

I'll take it to the Bell store tomorrow and see what they can do before doing anything else though.
[AT&T Samsung Galaxy Note II] Cab121:
If you can turn it on and see the OLED is providing images then its fine. The didgitizer is all you need to replace. The ifixit link is the best place to learn from. I replace screens on many phones and as long as you follow the golden rules your going to have a great repair experience.

1. Ask or search before you guess

2. NEVER EVER force anything. If it wont budge seems to require force. Check your sorce and ask first.

3. Double check all your connections

4. Keep a clean work space with plenty of light.

5. Stay geounded. (Usa a mat, strap, or whatever.)

[AT&T Samsung Galaxy Note II] majorbgss:
10 dollars more... every month
[AT&T Samsung Galaxy Note II] sodomanaz:
Plus deductible of $200 I believe.
[AT&T Samsung Galaxy Note II] Astom22:
That's why I waited to buy from Best Buy, it's$10/mo, but no deductible. You might get a refurb if they can't fix it, but at least it is free.
[AT&T Samsung Galaxy Note II] powerwagon:
Does at&t give you a new one if they can't fix?
[AT&T Samsung Galaxy Note II] pyo:
They have 2 insurance options

1) $7.00 - Insurance Only

2) $10.00 - Insurance + Better CS + GPS Location Services

When I was in the store to change sim cards, the in store rep told me only the $10.00 was available. However, when I called into AT&T CS, they allowed me to chose just the $7.00 option. $200.00 deductible still applies.

I believe it was covered in a previous thread, but Best Buy insurance does not cover lost or stolen phones.
[AT&T Samsung Galaxy Note II] 45ACP1911:
Yeah my wife got the same deal and looking online at the bill I lold and unchecked the extra $3 as I'm smart enough and don't need att's help in regards of setting anything up or any kind of usage.
