Hi I read through the forums and posts, but did not get a topic related to my issue. may be I missed something!!
My Samsung vibrant was connecting to wifi networks at home and office properly for almost 2 months and today it suddenly started acting strange. It detects the wifi connects to it then keeps disconnecting and connecting every second. Really worried as this is an unlocked version and I recently rooted it too. But even after rooting the wifi was working fine.. No idea.. what happened suddenly Plz help..

I'm going to assume you mean it isn't connecting at your office? Samsung Galaxy phones are notorious for having connection problems with enterprise routers, mine had the same problem last year.
The big problem for me was, that it was my school's wifi all together, and since I live here at my university, I had to go and up my data plan because, well quite frankly, you can't do jack **** with 200 mb of data.
I tried factory resetting, flashing new ROMs and kernels to no avail; however about 2 months ago it just started working for no reason and has continued to work since.
Good luck.
Thanks FLAC... Like you said... It startedWww working automatically. Very strange...
Hi there, i've a galaxy s4 gt-i9505 since dec 2013 and i've been experiencing the wifi button stuck in dim green (wifi stuck with that activating ... Message and not working) and not working since ive bought it. It came originally with the android 4.3 stock rom. First i thought it could be a hardware problem but when i reset the phone to it factory settings wifi starts to work again. Ive noticed that if i stay with only one wifi network registred (the one i use to reconfig the phone during the first reset) the wifi works fine, but when i try to connect to a second wifi (any router) the problem arises and the only solution is to reset to factory settings again.
Ive read tons of people complaining about this problem but ive never heard of this second wifi netwrok issue... I dont know wether android loads a different config or modem driver for the first wifi network registred during the first boot but the problem only comes after i try to register a second one. Ive tried all wifi config like keep wifi on allways etc but nothing seems to solve the problem. Ive also tried the airplane toggle trick but didnt work. Ive tried other stock roms from other countries like germany dbt but always on android 4.3... Any help is appreciated. Thanks!
Im on i9505vjuemke now...
So I was trying to tether from my N910C to my old N7000 to try lollipop on it but I couldn't find it. So I narrow it down to having Bluetooth on, when it is off I can find the N910C on my n7000 but no way to see it when Bluetooth is on. No device was/is connected to the Bluetooth at those tries
No one has 2 minutes time to test it?
Today I tried again to tether to a Samsung tab the Internet from my N910C. I tried everything but couldn't find it on the tab at all, as it was not existing. After that I tried if a 5s could find it but that lead to nothing.
Now I think the phone is a refurbished one since it has 2 lines from a black marker on the back where the battery has it's place, top left side, as a X or something like that.
So please ppl check if tether works.
Phone is from Romania a SM-N910C and it is used on Germany, since I wanted a exynos version of note 4.
Thanks for the help
My brother gave me his old Galaxy S4 E330K. Wifi Bluetooth doesnt work. What I found out is he flashed it with a 5.0.1 Black edition firmware of e330k. I tried flashing it with 4.4.2. Wifi and bluetooth still doesnt work. And whats confusing is the wallpapers are for s4 black edition but the rom i flashed was not a black edition one. Is this wifi and bt already a hardware issue?
Sometimes when a ROM is installed you need to run the "wiping" processes 3 times before you get install a different ROM.
Or flash the rom twice to make sure that partitions have been overwritten.
Or, your wifi chipset might have been burnt. This is what happened to me about 3-4 weeks ago. One day I tried to send some files via BT. BT turned on, but could see no devices at all. A couple of minutes later, the wifi went the same way. Turned on but I couldn't see any available networks. Another couple of minutes later, neither wifi nor BT didn't turn on anymore.
Opened the device and saw the chipset burnt
I read similar stories the same time I experienced these problems; I think for a lot of people S4 is starting to break.
Try to find out if it's a hardware problem or a flash problem.
Cheers!
Yesterday came the phone at home, did all updates to the last (LRX21M.5.0.0-RU1.1.134 YD201 ). The WIFI does not work if I walk away more than two meters from the router (the rest of my phones, printers, laptops work more than ten meters away, at different heights). Is there any solution? I can not work in the room, in the kitchen, bathrooms ...
Greetings.
If you're using canal 1 or 13, change it, some wifi card are bad with theses.
Check if you are connected using 2.4GHz or 5GHz.
5GHz has much worse range and does not go through walls really well... Usually, the range of a 2.4GHz connection is much better.
Thanks.
Unfortunately, I change both option and the problem is the same. The rest of my mobile, pc... work perfect, only yotaphone 2 has that problem... Any suggestions?
I try many xda tutorials and the WiFi is ok on 4.4 but it dissapear on 5.0. I try several changes with the radio folder but it is imposible it works in 5.0... Any idea?
Hi Alberto. I have the same problem with the wifi. It doesnt work fine in 5.0. It doesnt work fine with radio folder from CN neither. The yota wifi only works fine in 4.4. In fact, I have check that he bands phone are a little weaks in 4.4.
It is Y201. I buy it in dx.com.
It cames from HK.
Lte works. I am in spain.
It has snapdragon 801 qualcomm MSM8974 PRO-AA. You can see with CPU-Z. May be the problem is the processor.
Can somebody tell me which processor has?
May be Honk kong version has diferent processor.
May be that is the reason why it has not support.
Does anybody know anythink about?
Alberto, what has you done?
Thanks.
I can´t fix it, friend. My version is the y201 and I am from Spain, too. Bad luck...
Maybe I found a workaround. My YD206 seems to have similar problems but I'm not sure.
I have a YD206 (4.4.4) CN re-flashed to RU 1.134 (5.0).
WiFi signal is available and the icon indicates good signal quality. But when streaming videos / downloading udpates I get like 5-20 KB/s (yes kilobytes).
So I played around and found that WiFi and Bluetooth don't like each other.
Turn Off Bluetooth = WiFi works well
Turn off WiFi = Bluetooth works well (less Bluetooth glitch with my car)
Maybe this helps someone.
Thanks, Sekal, but the problem continues.
Same problem here. In 4.4.3 works flawlessly.
@albertovk, if I am not wrong, @sekall12 said recently in other thread that he thought that he had fixed this issue by restoring to factory defaults.
I made several hard resets without results, unfortunatelly.
Some conclusions:
My yd201 only works well with wifi in 4.4
I think that it is not a really yd201.
In China the phones dont have actualizations, so they are cheaper that because it doesn`t run ok with lollipop
Then, my yd is a false yd201, or a yd206, or a false yotaphone.
May be they are an group of items fixed too that somebody are selling.
However I think that it is a China`s phone sold as yd 201. It is false.
I can`t undertand how wifi of others yd206 runs fine in lollipop.
Bad luck.
Try a factory reset. It's the last hope, because you lost all your data, including internal sd card content. So backup everything, including the SD card (for sms/mms/call log i use MyBackupPro). Don't count on Google autosave to restore your apps data, it won't work in case of factory reset.
I have problem with wifi that sometime disconnect, micro-lag, some app force close. Since the factory reset, all problems are gone (wifi is stable, no lag) And since my phone is like a virgin after this reset, I root the phone, so i can make full phone backup.
