[Q] WiFi permanently broken? - Nexus 7 (2013) Q&A

Hey guys,
My wifi seems to be completely broken as even after multiple factory resets, it still does not work. I have used the stock factory images from google to install 4.4.4 and even today installed 5.0.1. But still the wifi does not work.
The tablet is able to scan for networks and find my home router, but when I connect it stays stuck on "Saved" and won't connect further. A few months ago I was trying to spoof my mac address and it seemed to stop working after that, could that be the permanent cause?
What would you recommend? I am past the warranty period but got the tablet from sainsburys UK

Have you reset your router ? If not, cycle its power and then power up your tablet and try to connect. Sometimes some routers think a device is connected when it is not.

I really don't think it's router related as I have had two different routers over the time the WiFi has been broken (none of them work). Also I've tried connecting to my phone hotspot but still the same problems.

WIFI Data freezes and locks up my router

Hi All,
I have a D-Link DSL-2740BR N 300 modem router. When I connect my HOX to it's Wifi I get data for about 10 seconds and then it totally locks up. I still have a connection and good signal, but no data come up or down. If I now leave it connected after about 10 minutes all wifi data on my router stops working so no other devices can use it. As soon as I disconnect my HOX from the wifi data returns to all other devices!
I have set the channel so it's not on automatic selection and I have given my HOX a specific DHCP lease, other than that I can't seem to change any other settings on my router that I can see would influence this.
Does anyone have ANY hints coz I don't feel like forking out for a new router and this is just ridiculous!
Thanks in advance.
this happens at work, my hox connects to a linksys wag120n, which is acting as a wap, its connected to another netgear prosafe router.
sometimes, not always, when the hox disconnects, it stops the internet working for all connected devices, even if they aren't using the wireless router at all! then i have to reboot the wireless router, not the other one, to make everything work again.
it doesn't do this at home, it's weird, i've tried playing around with the router settings but no difference... really annoying problem
Did you try to chane WPA to WEP encryption method? It may help. I had the same kind of problem with my Zyxel router.

I haven't tried that. I have had issues with ROMs on my old phone (X10) that it couldn't connect to WPA, but I didn't even think that could be a problem as it does actually connect... It's worth a try I guess, but I think I'm gonna have to try buying a new router...
Cheers.

Yes it is a really annoying problem. I do know that it happened less often with the original ROM & Kernel, but who am I kidding? There's no way I'm going back from CM9!
ive tried a factory reset on the wireless router, will report back whether it helps or not.

Ahh! Thank you! That totally fixed it! I can't believe that could even be a problem... Do you think it's the phone side, or the router side that's having issues with WPA?
Thanks so much!
btw, a factory reset didn't help, however, i have changed my 'Network Mode' option to 'G-only' instead of 'Mixed'
so far, so good, it's been a day or two now, one x happily connecting and disconnecting as i go in and out of office, and the internet hasn't gone down yet!!
glad to hear you got yours working properly as well RaVe-N

WiFi stuck on Obtaining IP/Avoided Poor Connection

For some reason, my Wifi connectivity on my GNexus has gotten really bad lately. I'm trying to connect to my home router (Netgear WNDR3400), and it gets stuck on a loop at obtaining IP address then avoided poor connection and it keeps reseting back and forth. It only manages to connect maybe 20 mins in the day and it looses the connection again.
Reseting the router only fixes the problem momentarily then the next day it can't connect again. The router is working perfectly fine in my house w/ the computer and laptops. iPhone and HTC Thunderbolt are also perfectly fine.
What can I do to fix this?

Have you tried assigning a static ip address to the phone?
Also what type of network? My phone does it on a 802.1 wireless b network with identity security (individual uname and password to connect) Which is what my university uses... annoying it was, but i found out that foxfi was causeing the issue. But im assuming your home network isnt like that.
How do I assign a static IP to the phone?
My router is 802.11n. And it has network security, secured by WPA/WPA2 to be exact.
App called WiFi static will let you set a static IP within a dhcp network. You probably can do it through your router as well. I would read up on static vs dhcp if you have never set up a static IP before. Also you'll want to see what all of the clients ips are so you don't create a duplicate.

Try to flash another Rom.I had the same issue with cm 10.1 based roms, but after flashing aokp based roms problem was solved.

Anyone having this issue on the Verizon stock ROM 4.2.2? I cannot connect to any wifi with DHCP. The only way I can connect is if I enter at static IP. I have tried about a half dozen access points with no luck. I have even done a complete phone wipe of data and tried reconnecting without logging into my google account to sync down my wifi settings. This pretty much prevents me from connecting to any public wifi hotspots unless I can guess their IP range. I have never had anything other than the stock ROM and OTA updates. Is there something somewhere I can clear or reset to fix this? It worked at one time long ago prior to jellybean I think.

G3 does not connect to work wifi

Picked up a new AT&T G3 yesterday. Had no problem getting on my wifi at home. However, I've been unable to get the phone to connect to my work wifi. The phone detects the network, I put in my password, but it just will not connect. I've still got my Galaxy S4, and that phone connects fine. I confirmed that both phones have the same settings, and the G3 will not connect.
I've reset the phone, powered it off and back on, forgot the network and reentered the password, turned wifi of and back on, and still no love.
Any other suggestions before I return the phone?
Restart router? Login to the router and check logs? Wipe router password (no password) then try to connect.
Trying to get that accomplished will be fun. Might just return and stick with my S4.
Mines had the same issue out the box, wouldn't connect to neither mine nor the neighbors WiFi, restarted my router and all has been good...
By restarting the router, do you just mean unplugging it for a minute or two, then plugging it back in? Tried that with the router in issue with and it still won't connect.
I'm having this issue with the wifi networks I have at home. I'll go to the settings, enter my password and it will instantly not connect. However, the NFC tags I have already set up before I had my G3 still work and allow me to connect without issue. Strange. This is on the 16GB D855

Yes. But if router is setup as access point then will be connected to the switch and or firewall. Worth to restart it as well. I recently had this issue with airport express. One way to fix it was change router open(no password) than cannect your phone and then stick the password back.
Just to follow up on this, I was able to gain access to and play with my router settings at work. I changed the network to open without any security, and the phone still would not connect. I then changed the network mode from "b & g mixed mode" to "b only mode" and it immediately connected. Not sure what the difference is, but hopefully our computer guy will let me keep the change.

it was working fine up until a couple days ago, then i installed that netgear aircard app and it somehow messed up my connection to that aircard? ive uniinstalled that app
hi, im suddenly having trouble connecting to my wifi HOT spot aircard ...all my other devices can connect to it fine so im positive the problem is with this nexus 7 FHD
it will connect but then after few seconds autodisconnect...must have tried this 100 times it keeps doing this :

is there a way to RESET all the wifi cache on the nexus FHD? similar to how to wipe data on any apps in apps settings? thanks

The only two things that I can think of to suggest would be to go into wifi settings and have it "Forget" that network then reconnect. If that doesn't work maybe fastboot flash the system image. I don't know which system files would relate to your problem, probably something inside the etc/wifi folder, just guessing.
ended up, changing my aircards wifi security from WPA/WPA2 PSK to WPA AES or something and that did the trick... my nex7 was able to connect and STAY connected
maybe its finicky about what encrytpion witi security it can connect to

That's weird! I've always used WPA/WPA2 PSK with no issues even for tethering to my N5 or One X and I've done a lot of tethering over the last couple of years. Glad you got it sorted out!

SM-T520 Wifi issue

Hi, I've tried all the troubleshooting steps on how to fix wifi connection but it seems there's no luck.
I've already change the firmware but still no connection.
The problem is, I can connect to a wifi but it has no connection. It will only "saved,secured" and that's all.
Anyone can help?
Same issue here.
I'm starting to think that the eletronics trash can is the solution...
My Samsung Galaxy T-520 detects all Wi-Fi networks, but it doesn't connect to any. The status shows "saved, secured", but it fails to connect. I tried everything, switching on/off passpoints, bluetooth and whatever, even factory resets (twice). I also tried to start the device without the Google account, skipping everything. I also tried a cell phone access point, it's all useless. All my other devices work, so it's not the router. Maybe it's a hardware problem. It suddenly stopped working
