[Q] wifi no longer working??

Ive had my 300 for about 2 weeks now, no issues nothing, its not even rooted. Everything was working fine till about 2 days ago when the wifi would not connect. I would restart the 300 and it would stay connected for about 30 seconds or so before it would disconnect. Whenever i would go to the wifi screen and select connect it does nothing. Any ideas?

Try deleting and recreating your wifi connection. Get it once in a while with my phone.

Get Wifi Analyzer and make sure you're using a clear channel. There could be interference from another wifi network.

Wifi issues please help.

Suddenly my tab is not connecting to my home network, it sees it but I have to reenter the wap password every time. Anyone have this issue? How can I resolve it?

Please explain what you have exactly done in between working and not working. Anything at all.

Haven't done or changed anything. I have wifi on my tab turned on at all times. When I leave my house the tab disconnects and when I come home it reconnects until yesterday. When I got home yesterday I noticed it wasn't connecting, my tab recognized my home network with no problems but I had to reenter the password. Very inconvenient if I have to enter the password every time I am home.

Have you tried the obvious, reboot the router, then reconnect?
Also, does it forget the password with any other router?

I have the same problem too. And it doesn't only happen at home but also other networks.

i had noticed since the upgrade (via mobile odin), my tab 7.7 longer see the 5ghz wifi network, however my note 1 and other devices sees the 5ghz network just fine

Samsung firmware bug reported in other threads for some certain routers.

WiFi broke after Flatline NVflash

Tablet can't seem to connect to wifi after doing the Flatline NVflash. Anyone has this issue? When nvflash was done, I reflashed TF700_10.6.1.14.10_WW_Boot_TWRP_2610 running on CROMi-X 5.0.3. Booted up to find out that wifi is not connecting. I even tried factory reset and restore my previous backup but still no luck. Don't know what else to do besides a fresh install of cromi, which I'm really trying to avoid.

I know that Flatline *uses* WiFi, but I see no reason how it could break it, at least across a reboot.
Reboot your tablet and post the output of lsmod and dmesg.

ok here's what came up after reboot

The log shows that the driver is loaded correctly, but WiFi is not turned on. What happens when you try to turn it on in Settings?

Or maybe airplane mode? if not it must be something on the router side.

Its on in settings but says "saved, secured with wpa/wpa2" with a blank wifi icon on status bar. Also nothing happens when I click connect. Airplane mode is off too

by blank you mean gray? id say its an issue with your network, try forgetting the connection and rescanning.

Router is ok cuz all my other devices are connected on it

Well the wifi module is loading ok and wifi is scanning so there isn't an issue with the tablet. try tethering your EVOs connection to the tablet and see if it connects

Yes blank as in just an outline of the wifi icon, not greyed or color filled if it was connected with full reception

Forgetting connection/scan and reconnecting many times already with same results. Wifi direct on tab doesn't pick up my EVO but my EVO is able to pick up tab n connected successfully. I'm going to try uninstalling notification toggle bc that's the only thing on my tab from what I can tell that has access to network settings

Well just my luck....tried everything possible relating with wifi but still no connections. Guess I'll have to format sd and do a fresh install of cromi. Btw I'm on d2sd and if I were to wipe internal, does that delete the androidroot nvflash folder sitting in the internal memory?

My wifi keeps disconnecting and reconnecting

Ever since my device got bricked and flashed the the original firmware, my connection on wifi keeps disconnecting and reconnects even though im like 10 feet away from my router. This bothers me because I cant play online games. Is there anyway to fix this?
Sent from my SCH-I800 using xda app-developers app

I suggest you turn off your router (or also disconnect the cord) for 30 seconds, turn off your WiFi on your phone, then plug it back in and turn on your WiFi again and check. Otherwise it might be a phone problem.

I'll give it a try
...When im connected to other wifi network this doesnt happen.

You should consider buying a new Wireless Router which is more powerful. As your statement, that this issue doesn't happen in other WiFi network, try to check the speed of your internet, traffic, etc.

My other devices works fine

try to forget the network, restart your phone and connect again.

So the issue must be the communication between your phone and the device. Try to restart the phone, or remove your wifi, and then enable it again.

try this
go to settings> WiFi > advance > keep WiFi on during sleep > select always on

I tried, the problem is still there

problem solved and a question-why does unstable wifi mess with usb?
My phone kept getting disconnected from my computer. This was apparently happening because my wifi was unstable. Not sure why the phone disconnected, I was connected via usb. The wifi was unstable because I was using a proxy. When I use my comcast connection straight through the problems go away. If someone can explain why an unstable wifi can screw up a usb connection I'd be grateful. Windoze issues?

[Q] Wifi Drop

I have a rooted Nexus5 which aint running any custom rom. I have noticed that my wifi drops . the icon shows active on the status bar but there is no data transfer.
i thought it could be one of the xposed modules which might be interfering so i unrooted my phone and put it back to stock. The wifi signals were fine for a day or so and i am now facing the same problem again.
I downloaded the Wifi Analyser app from the play store to check if there is any interference from other routers in the vicinity. I have changed the channels multiple times but to no avail. At the same time my laptop & desktop connects fine to the router.
I am currently running stock 4.4.2 build # KOT49H

Try an app called "Root- Push Notifications Fixer". There are two versions one that requires a rooted device and one that does not I use the rooted one and off hand cannot remember the difference. Below is the playstore link:
https://play.google.com/store/apps/details?id=com.andqlimax.pushfixer&hl=en
This app resolved a WiFi issue I was having. I originally blamed my router/device but it was neither. I use it on both my Nexus 5 and 10. Read the app description for the issue it addresses.
Good luck.

I had something similar on my Nexus 5. The wifi speed would drop dramatically at random and it looked like web pages had stopped loading. My connection is 25Mb but the N5 would drop to 1-2Mb. I'd then have to turn wifi off and on to get the speed back up.
After searching around for the same issue a few people suggested turning off mobile data while using wifi. After doing this the speed has never dropped. I've since set up a Tasker profile to turn mobile data off when connected to wifi and back on when wifi is out of range/off.
Might be worth a try.

Its helping mate . will try it for a day or two to see how it works .

Me, I've tried everything and nothing helped at all. App Wi-Fi Analyzer tells me no signal. Tried a few kernels also. Waiting for rc of cyanogenmod to see if anything will change.

guys , looks like i have finally sorted the problem. I called my ISP and he suggested that it could be a looping issue with the router. He advised a hard reset which i have done now. i can now connect to wifi with my phones

sometime my Wi-Fi lost data even the connection is still on. I'm using Franco kernel r32. I don't know how to fix it. Can anyone help me to solve this problem?
