3G and WIFI problem

I have a problem with wifi and after using 3g, my tablet connect to wifi and 3g no problem, when I use wifi first and than 3g works great, but when I go back to wifi it can see wifi around me for a second than begin to scan and this is it, I have to hard reset my tablet so my wifi work again. Removing SIM doesn't help. I think is issue in software. Is there any software update or everyone has same firmware? Is there any solution?

same problem :-(

one more here, and lenovo does not do anything about it

Two news, bad and good. Bad news: there is solution for this problem but root is needed. Good news: root is achieved and would be avalable soon

[Q] 4.4.2 wi-fi issues

HI, I've got constant wi-fi issues on ma nexus 4 4.4.2. It certainly isn't the hardware, I got a replacement and the problem persists, which annoyed me cos all my photos cos messed up in order . anyway my wi-fi always disconnects and doesn't connect, this keeps on happening. im on a dual band router. is this only on 4.4.2? this problem only started happening in the last month or so. as far as i know it doesnt happen with other networks but when my wi-fi on my nexus drops, it doesn't drop with any thing else in the house. thank you
p.s. - i have a feeling it may be to do with something about the dual band. also the problem doesn't persist on my iphones, does this happen for you too?
was on paranoid android 4.2 beta with matr1x now on complete stock though

In your phone's Wifi settings, select either 5.0 Ghz or 2.4 Ghz and see if it helps. Also, try to search for Wifi fix by Kalo in the Development Thread and then flash it in recovery.

[Q] Wi-fi issues

About a month ago I noticed that my wi-fi is working weird. It is connected, but I can't use the Internet. Looking at the wi-fi icon I can see that it is sending data to my router, but it is not recieving anything back. I basically have the arrow going up, indicating upload, but no arrow down, indicating download. After a few minutes (or after restarting wi-fi) it goes to normal for some time and then it stops working again. I'm currently on optimised CM12.1, but it doesn't matter which ROM I use. My router works fine. I checked with another phone while my s4's wi-fi wasn't working. I was considering updating baseband and modem, but I wasn't sure which one to use. I'm in Poland and my carrier is Mobile Viking, but they use Play infrastructure (or T-Mobile, if play is unavailable). It isn't anything that would make me change my phone, but it is a bit annoing.

It's like you said. The only thing you can try is changing your modem.
Do you have a stable connection on other wifi networks?

I have no way of checking other networks (living in a small town with no public wi-fi). Which modem should I use? I'm in Poland nad I bought my S4 in a store (not from any carrier)

There is no best modem. You have to try it for yourself. I would suggest taking lollipop modems, but you have to be on a lollipop bootloader for that.

If I am on lollipop rom, does that mean that I have lollipop bootlader? When I bought my phone it was on android 4.4.2

Since lollipop my wifi has been terrible on my i9505 stock rooted. My iOS and windows devices are rock solid but sgs4 has crap connection strength. On previous devices the radio with the upgrade was normally to blame but I'd welcome any suggestions. Does cm12 use the same radio as stock?

Big Wifi problem

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.

Wi-Fi calling on vodafone uk

Hi guys
Just got a and s8 and its the first phone I've been able to use Wi-Fi calling on. I'm on vodafone uk and the WiFi calling works okay. I've just got a question though.
At home I generally get an okay mobile signal but the WiFi calling symbol remains even though i have 2 bars. Is this normal? I though WiFi calling would only kick in when your signal was really weak?
Many thanks

Hi just a question do you have any problems with wifi calling? Just that I'm on vodafone and when using wifi calling no-one can hear me when I talk.

I tried it today mimo2008 in airplane mode and WiFi on and it worked okay for me. Are you running a vodafone firmware or a standard uk one?

Had the same issue in that quite a few times the person at the other end could not hear me. Also the WiFi calling symbol would remain even after I was out of range of WiFi!
Used to work fairly well on my old S7. Given up using it for now and turned the Sure Signal back on.
I'm not using a Vodafone firmware BTW.

It's strange because it only works in airplane mode not in normal. I'm running vodafone software unfortunately.
Thx for letting me know.

Are you guys connected to 5ghz WiFi when you are having problems? I had the chance to try WiFi calling at work today where I don't get signal. It worked really well and disconnected as it should as soon as I walked outside and had a couple of bars mobile signal. I tried this a few times. The only difference to at home is that we only have 2.4ghz WiFi at work.
Came home and forgot the 5ghz network and joined the 2.4ghz one. Magically it just works now. As soon as I'm down to one bar it comes on. Then goes off when I'm stood by the window and have 2+ bars.
Edit: Seems that didn't fix it after all. I'm sat here with 2-3 bars and WiFi calling remains on. Oh well hopefully in a future firmware update it might get fixed.

Just to update I'm now having the problem of the other person not being able to hear me. I've had to disable WiFi calling now as it's too buggy. I've left a message on the Vodafone forum where others are having the same problem. Apparently they are looking in to it.

Yeah I've been told it's not compatible with nougat which i think is a load off bull.
If it was the case then it would effect other carrier's

Have they said if they are working on a fix mimo?

Hi @rob77
This is the email I got from vodafone.
Hello,
We?ve just investigated the fault you are experiencing with wifi calling. Your phone is currently running the latest version of Android (Nougat) which regrettably is currently incompatible with wifi calling, as soon as an update is released to Android wifi calling will resume normal service on your phone.
Regards,
No time scale I'm afraid.

Thanks mimo2008
Oh well I guess I'd better invest in a sure signal for work then.

Your welcome Rob hopefully they will get it fixed soon.

Bought a sure signal yesterday and have set it up at work. I've got to say it performs really well

@ Rob77 - Funny, cos it worked perfectly fine on my S7 running Nougat?

@Richy101 I've read quite a bit on the Vodafone forums and it does seem mainly s8 owners complaining of this problem. I've submitted a ticket and would like to see it fixed but the sure signal is actually better for me at this moment in time. I only need WiFi calling at work and the sure signal supports texts as well. At home I get usually get 2 bars 4g and falls back 3g if the signal gets too low.

Just received a large "bug fix" software update which seems to include updated carrier software (VOD_0058 to VOD_0061) - does anyone know whether this WiFi calling bug was fixed?

Still broken for me with the latest update; no sound transmitted from my phone to the remote side

How frustrating - I've not had that problem yet since the update
EDIT: I notice Vodafone appear to have updated their site to say S8 is officially supported so they think any issues are now fixed
