[Nexus 10 Q&A, Help & Troubleshooting] legaleagll:
With 4.2.2 I had no issues with wifi and can still go back to that version and have no issues, but with version 4.3 and 4.4 I have had and still have the following problem.

I have a list of known wifi connection points as well as available access points. Everything appears as it should, but the wifi will not automatically connect to any wifi (protected or unprotected/known or previously unknown) without first turning the wifi off and back on. Additionally, this only works if the persistent background wifi option is toggled off. If I do toggle the wifi on and off and connect to an available access point everything is fine so long as I remain in range and stay connected. If I go out of range and lose the connection, when I next reenter the range and the access point shows up on the list it will not connect unless wifi is cycled on and off. This happens every single day at work and home, although there is a workaround, it is quite annoying to have to cycle the wifi off and on. The networks will show as available and if I click on them and try to force it to connect, it still won't work unless I cycle on and off.

I have seen prior threads with this issue on 4.3 and there was a topic in the official Google issues page and was frankly hoping desperately that 4.4 would fix it, but alas, it has not. I know it is not the device itself since reverting back to 4.2.2 solves the problem.

Does anyone know of a permanent fix to this wifi issue that doesn't involve reverting to an older version of android or some kludged together solution?

[Nexus 10 Q&A, Help & Troubleshooting] sttovo:
Are you stock? Maybe try another ROM? I had the exact same problem, but my problem was my wifi AP.

1- My router was setup for a/b/g/n, I set it to only what I really had using the Wifi AP, which was g/n

2- I had a weird cable modem to router to Wifi AP setup. The router was handing out IPs, not the Wifi AP. I removed the router and only let the Wifi AP give IP addresses (DHCP). It seemed like the "further hops" away that the DHCP addresses were, the more issues i had with my Android connection.

No other devices on my network had these issues, but doing the above made a world of difference.

All that made my connections lightening quick, no issues at all since then.
[Nexus 10 Q&A, Help & Troubleshooting] nigelhealy:
odd Wifi behaviour

I got a refurbished delivered N10 last evening, came with 4.2.2, played with it a little, did a network benchmark test (FTP off a LAN NAS) and was getting comparable peformance to my other fastest system (a Thinkpad Ubuntu laptop). It seemed stable but I only used it for like an hour as 4.2.2. I was getting FTP of max 4MB/s over a N-router.

I then let it OTA to 4.3 and then played with it for some hours. Issue I found was the Wifi would work and then have "authentication problem" I had to turn Wifi off then on to make it connect to router. I've had that issue with other devices at times. I was thinking of staying on 4.3 to allow 4.4 to have another bugfix (its not been long out on N10) but I had a key issue for me (PPP Widget didn't work) so I did a stock 4.4. flash upgrade.

On 4.4. the Wifi speed is still fast, but periodically it just stops working, a glitch.

One key thing that stands out is the N10 is connecting at much higher Mbit speeds than any other of my devices, it is showing 130Mbits vs say 20-65Mbits on other devices. I'm wondering if my N10 is "too good" for my router an old low-spec refurbished model (Cisco E1200 v2, which I flashed to latest DD-WRT) ?

I'm not so far disappointed with network performance, just network stability, but I can't tell for sure if its the N10's fault or my router's fault. I'll play with settings a while til I find something stable.
[Nexus 10 Q&A, Help & Troubleshooting] Ichiban Rei:
When I first got my N10 I had a lot of trouble with wifi connection. Mostly authentication issues, or it would authenticate but not have internet access. It was frustrating, and Google's support was clueless.

I then tried using wireless tether from my N4 and it worked as it should. The issue ended up being the Arris router that Time Warner uses. I bought a Linksys router and have had 0 issues since. So if you're using an Arris router, or it shares the same chipset, that might be the issue.

The router is the Arris DG860.
[Nexus 10 Q&A, Help & Troubleshooting] nigelhealy:
Good anecdote.

Well in our house, the proliferation of gadgets has changed progressively to a large number, I make it 14 devices from an initial 2 devices 5 years ago. I count 4 wired and my 4 devices, my son's 2 and my daughter's 3 and my wife's 1. They all compete for router bandwidth, Wifi spectrum, router CPU / cache.

What I might do with this high-performance (capability and demand N10) is segment my network using an old G router I hard fix to non-overlapping channels from N-router, and connect the low-spec devices to the G and high-spec to the N. That will involve no $ and naturally reduce congestion. I run a NAS and download media to it and then stream to gadgets off NAS so I'm Wifi-limited often more than Internet-limited, and even tweaking I get 2MB-4MByte (16Mbit~32Mbit) off a NAS is making my typical LAN speed the same as the Internet bandwidth I buy (16Mbit).

My NEtbook (EEE 1015PN) if it ever felt a Wifi hiccup it would lock-out that frequency and so not see the router til I powered off netbook and remove battery.

I do wonder if some of the N10 Wifi complaints are really just generic or bad combinations with router or "straw that broke the camel's back".
[Nexus 10 Q&A, Help & Troubleshooting] droidfan77:
I'm having wifi issues with my N10 as well. I had a few wifi issues at work, but not at home while using 4.3. Now with 4.4 I'm having serious wifi connection issues both at work and at home. In fact my N5 running 4.4.1 is having issues connecting to wifi both at work and at home. Not as often as my N10, but it still happens. I'm running stock on both and have no problem connecting to either network with my laptop.

I've installed wifi fixer, but so far it doesn't seem to be helping much. Does anyone have any suggestions on what might be done to fix this that doesn't involve rooting either device?

[Nexus 10 Q&A, Help & Troubleshooting] nigelhealy:
experiment with the router

Some of your problems might be just coincidence, something changed in your area around the same time as you upgraded. Some of these are just the wrinkles of firmware of device vs firmware of router, some combinations work bad and isn't really "fault" of Android in that you can't test every combination. You could wait for a fix from Android... or just try to avoid the wrinkle by changing settings on the router. A common thing is to move the router from auto to fixed channel and fix to 20mhz narrow. Go the place you mostly are with the N10 and use a Wifi analyser to find the least-congested channel and then set the router to that. What that does is reduce channel-hopping and gives less opportunity for firmware issues on both router and the Android device.

I also had a problem with my N7 when I moved house. The answer was to flash DD-WRT on my router and the problems went away.

So either wait+complain or go look at your router now.

Right now I have DD-WRT on an old refurbished Cisco E1200 and I set it to channel 3 with 20mhz and I got very good Wifi performance. With the stock Cisco firmware I was getting Android Wifi drops and poor performance. Yes, that's partly Android's fault but I fixed it myself quicker flashing firmware on the router.

I also took opportunity in DD-WRT to setup IPTABLES for a transparent proxy so all the devices in my LAN now share a large harddrive as http cache so e.g. any downloads from Play store for say my N4.... is cached to my N10 so I only ever download anything once.

If you have issues still with the N10, then what I find solves a lot of problem is do a stock flash of 4.4.2, on setup untick all the backup+restore from Google, then manually install and configure yourself to make it "vanilla". That often fixes accumulated wrinkles unique to your history of your device and places to more mainstream with less likely of having a unique problem. I do that on all my Android devices now (N4, N7, N10).

Similar wifi problems here

I've had similar issues with my N10.

I will have fast internet speeds (30+ Mbps) and it will just freeze. I'll be watching youtube and it will start buffering. Doing a speed test on my phone shows the speeds as normal. It makes no difference whether connected to 2.4 GHz or 5 GHz wifi.
[Nexus 10 Q&A, Help & Troubleshooting] bflatmajor:
I just resolved my WiFi issue this past weekend. Connectivity is rock solid

Here is what I did I.

Purchased my own cable modem/router. New router had updated firmware. time warner cable modem did not.

Change beacon interval from 100 to 20 on router and repeater.

Made sure router was on a less congested channel.

All is rock solid

YMMV

Great! Often just tweaking settings can do wonders. I flashed DD-WRT on mine and it solved a lot of issues on an old low-spec router.
[Nexus 10 Q&A, Help & Troubleshooting] jfed:
Hey Guys,

I posted this in General section but saw this so I will add this info:

I just want to share what and why I did it. First off I did not have problems with my wifi on 4.2.2 with the Nexus10. the second that I went to Slim Kat and Vanir 4.4.2 I had weak wifi signal at work and at home when my nexus 7 slim kat and my galaxy note 2 Vanir did not. I noticed that RAM was also weird on the nexus 10. Even though it showed 2gb of ram on the specs it was only showing 1099 on 4.4.2 when I show that I have 1647 ram available with 4.2.2.

Concerning the OS using Ram. Google said that they would make Kit Kat more RAM friendly but I was using 535mb of RAM for 4.4.2 and right now I am showing only 357.3 mb for 4.2.2. I am using the same apps launchers and screen savers

I just flashed back to 4.2.2 this morning so I will update later, I do see an improvement in the wifi though.

I just want to say that I love Slim Kat and that is why I am on the 4.2.2 I just think Google somehow hosed up the wifi on the Nexus 10.

B][/B] Ok so I am at work and have went back and forth between 4.4.2 and 4.2.2. the 4.4.2 connects and disconnects back and forth. When it does connect to router but it says poor connection and it is only 24mbps. "It drops way more than connected" I am 45 ft from router in an open environment.

The 4.2.2 Slim Kat has a fair connection with 78 Mbps and has not dropped once. So I don't know what the difference is with Kit Kat compared to Jelly Bean but for my nexus 10 my wifi is great now with Jelly Bean. I wish I could figure out why and fix but I do not know programming.

I also installed on both 4.4.2 and 4.2.2 a app called WiFi Connection Fixer *Root* by ZEXTR. It did not help 4.4.2 but it did help with 4.2.2. this app helps connect to poor connections or when Android says avoided poor connection.

I don't know why the Nexus 10 is having issues with wifi with KitKat but I wish I could fix it. So I will be on 4.2.2 until a new version comes out and I will test it to see if it fixed it.

update; I have used 4.2.2 all day with the wifi connection fixer and I have not dropped wifi once and the download speed is fast. It is much faster than what 4.4.2 was, at least on my tablet.

Nexus 10 4.4.3 WiFi Bottleneck Problem

Hello there everyone,

I just wanted to confirm that I personally found a fix on my end for my Nexus 10 WiFi bandwidth problem that was definitely evident for many people that upgraded from 4.4.2. First off, I'm totally stock. I will most likely root & ROM this thing in this near future. I was having a bottleneck on my Nexus 10 around ~2 mbps when I tested using the speedtest.net application (may not be the best measurement application but it works). I ended up fixing the problem by changing my router settings in the WiFi section of my browser based software to N/G Mixed instead of just Mixed (which allows 802.11a/b as well as 802.11g/n to run on the router's WiFi signal). I use DD-WRT on my router as well so that may have played a factor in it but I did NOT see an increase in bandwidth until making the N/G Mixed change in the settings. I found this suggestion earlier in the thread and wanted to give it some credit. Thanks everyone!

한국인이시군요.. 방갑습니다^^

제가 영어를 잘못해서이겠지만.. 설명을 보고 이해를 못하는 사람이 상당히 많네요..;;;

메탈케이스를 장착후와 탈찰후 다운로드 속도가 엄청나게 차이나더군요.

제가 설명하고자 하는 내용은 일반적인 메탈케이스와 알루미늄케이스를 착용했을경우 LTE다운로드 속도가 급격하게 하락했습니다.

그래서 다운로드속도와 업로드 속도에 민감한사람이라면, 되도록이면 메탈케이스와 알루미늄케이스를 구매하지않는게 좋습니다.

제가 테스트해본케이스는 총두가지입니다.

하나는 일반적인 금속형케이스와 실리콘형케이스. 대신 두개다 두꺼운케이스입니다.

일단 모든 케이스를 탈찰했을경우

다운로드속도가 20회실행했을시

MI9와 MJ7 의 다운로드 속도차이는 변화없음. (MI9보다 MJ7이 핑속도가 더좋음 그리고 업로드 속도약간향상)

메탈케이스를 장착했을때 LTE 다운로드속도는 20회테스트로 평균 1메가 내외로 급격하게 떨어졌습니다.

또한 실리콘케이스를 장착했을 경우와 탈착했을경우 속도는 같았습니다.

하지만 메탈케이스를 장착했을경우 다운로드 속도가 1메가내외일경우

실리콘케이스나 케이스를 장착하지않았을경우 다운로드 속도는 5~6~ 12~mb 까지 엄청나게 향샹됬습니다.

테스트횟수는 각각 20회씩 번갈아가면서 3셋트 테스트했습니다.

결론은 금속케이스는 LTE다운로드 속도에 영향을 준다입니다. 확실히 체감으로도 차이가 나는정도이네요.

단 Liquid Metal 일경우 이론상으로 전파에 영향을 주지않으므로 Liquid Metal로 제작된 케이스는 착용해도 큰 변화가 없습니다.

제가 말하고자 하는 요점은 이것입니다..ㅋ

[Nexus 7 (2013) Q&A] C5Longhorn:
I recently picked up a Nexus 7, unlocked it, and loaded KitKat yesterday with the factory image. I have set the device up now and would like to use a custom backup to take an image of the 7 and then store that image off of the device on an external drive since I only have a 16gb 7.

I have downloaded Clockworkmod ROM Manager to do this. Is it easily feasible to make a stock image and then transfer the image to an external drive? I'm having an issue installing the Clockworkmod Recovery tool, but I posted a question about that in a different forum.

Any advice would be appreciated.

Thanks,

[Nexus 7 (2013) Q&A] iPWNtehNOOB:
I presume you have a custom recovery installed in addition to the ClockWorkMod Manager? If not, use the WugFresh Nexus Root Toolkit to install that, then boot into the recovery and select the backup option. It will create a folder on the root of your device called clockworkmod which will contain your backups. Just copy that to your PC, and transfer it back to the device when you need it.
[Nexus 7 (2013) Q&A] Wrngway:
I've used ROM Manager a fair amount for creating backups. It works well, but like was said previously, you'll need to flash a custom recovery. The two main choices are Clockworkmod (CWM) and Team Win Recovery Project (TWRP). CWM works well with ROM Manager in my experience on another device.

I've found TWRP much easier to use though. It features a touch interface. You'll be able to customize the backup file name if you initiate a backup in recovery mode. The file name will also allow spaces, while CWM doesn't.

Check it out at teamw.in/project/twrp2. I think the recoveries are the same, but make sure you select the correct Nexus 7 model (LTE or Wi-Fi). You can flash the image in the bootloader using fastboot. Instructions are avalaible on the TWRP website.

From what I've read, the stock recovery for KRT16S is the same as KRT16O. I'm running the latest TWRP on KRT16O without issue.

Assuming your bootloader is unlocked, you shouldn't have an issue. Can you list the steps you're using to flash recovery? Maybe you're missing something.

If you have the correct driver on your computer and you're using fastboot, the command should be "fastboot flash recovery [insert recovery file name].img" from the fastboot directory.
[Nexus 7 (2013) Q&A] C5Longhorn:
Ok, maybe I was doing something wrong. The command line indicated it was installing correctly when I flashed it. However, when I rebooted to recovery it was never TWRP.

I just installed Clockworkmod Recovery so it was probably an error on my end.

Now, since I have made a backup, how can I identify where it is stored? I would like to move it to my computer since I only have a 16gb 7.

After installing ROM Mgr version 5.5.3.0, I launched the app and received the message that I needed to install the custom recovery. I followed the steps given in the app below:

1) Identified device as Nexus 7

2) Selected "Install Recovery ClockworkMod Recovery"

3) Selected 'Flash Clockworkmod Recovery'

1) Where are these Clockworkmod Recovery downloaded files going and how can I get rid of them? If I do a full wipe of the device to clear out these junk files that I may have downloaded?

Any input would be much appreciated. My goal is to set up my device, and take a base image that I can store off of the device on an external drive.
