Had this issue since I first bought the phone, wifi won't turn on anymore (instantly switches off). It used to, but the radio couldn't find any APs. I didn't check the MAC address, and now it just says unavailable. Bluetooth just won't work, and if it's on then I get a popup every 20s saying bluetooth has crashed.

Not enough information to help you. Unlock your bootloader and flash a full factory image.
I already tried factory resetting through the menus

I have a strange poblem with Wifi. Whenever I try to connect to any accesspoint, secured or otherwise, it displays "CONNECTING" for a while, then reverts to "AVAILABLE". Once in a while, by resetting or turning wifi off and on, Ill be able to connect and then everything is fine. But the moment I trun wifi off and back on, or suspend the unit the error returns.
Update: this is getting even wierder. I am able to connect to _secured_ networks without a problem, but I still cannot connect to unsecured ones.

it would help if you post your GSM/ROM version and to what kind of network you are trying to connect ?
Hi guys.
first my wifi became unreliable, it disconnected, didn´t reconnect sometimes etc...
now, it´s not working anymore at all.
when i go to wi-fi settings it says turning on, then the red arrow appears, then immediately it says turning off. down there comes a message "unable to scan for networks"
i searched the whole forum, but didn´t find a simlar problem.
i reseted it to factory, didn´t help.
it can´t be a router problem, ´cause all the other devices on the wifi work, even my friends myt4G.
any tricks or ideas anyone?
i got this form a friend in the states, bought last december, he ment, in the US they have mostly only 90 days warranty, in germany we got 2 years.. is this true..?
stock rom. 2.3
Try chaning the channel on your Wifi Router. Most of the new routers you can go to routerlogin.net from a computer that is connected to the router and change the settings. I had the same problem and it appeared all of my neighbors were using the same channels i was. I move to a different one and haven't had a problem since. It will not affect the SSID or the password So all of your login it stuff will stay the same. Any WAN connected device just might lose signal for a second or two while the router changes channels.
thx. channel was on auto. changed it to 11 out of 13. didn´t help. also, i have only 3 wifis in my neighbourhood, i can get with my pc. on the htc, it shows only mine + the direct neighbour..
it seems that wasn´t he prob here...
could it be a hardwareprob? anyone any knowhow on american warranty?
the wi-fi button is almost not responding anymore.. when i turn it off, it turns itself on again, when i go into wifi settings, ist keeps truning on and off again in an endless loop....
edit: tethering does also not work anymore. when i click on portable wif hotspot, it says error...
hardwarefailure?
i found these guys who have the same problems.

seems to be a gingerbreadissue... perhaps i´ll try downgrading first.
so i downgraded to 2.2.1 and it worked. got to bed, woke up, not working anymore "unable to scan for networks" again
For the last week or two I have been unable to connect my phone to wifi networks.
At first the problem would be that I was getting disconnected from any wifi network I joined, now I can't connect at all.
The wifi networks page sometimes (not always) does not detect a strong network even if I am standing a few feet away and the phone has previously connected and other APs are connected and working like my pc
If I try to connect then I get the "Connecting" status followed by "Saved,secured"
I have searched the internet looking for a fix to this and tried wiping the cache partition, forgetting the network, airplane mode toggling on and off, apps that wipe the known network list and some others including lastly a factory reset on the phone but nothing seems to remedy the issue.
From the wifi router I have tried using an unencrypted (open) connection
Now I think I may also be having problems with the bluetooth connecting in the car but I haven't had a chance to really investigate that one yet and it may or may not be related to the last factory reset.
My phone is not rooted.
Build no. LRX21T.G870AUCU2B0F3

Can anyone offer any assistance to my current issue ?

I have just confirmed that the Bluetooth in my car is not detecting my phone when it scans (the phone bt is switch on and the visible box being checked) so that's both radios with similar issues.

Im having same issue with wifi... sm-g900r4
I just stumbled on a clue, while using an app called 'wifi cleaner' there is a feature allowing you connect to wifi networks within the app. I type in the password, authenticating is shown on the screen followed by "incorrect password".
I know the password to be correct..
Mmm

I was wondering if you ever got this issue fixed?
I thought I had but the problem comes back in a different way.
Sometimes wifi connects but only connects at 5 mbps.
Now wifi will not turn on at all. ( radio button is greyed in settings)
I did find a thread on xda where some Motorola users were having the wifi off issue and it was due to a missing system file which could be replaced on a rooted device. However I don't have root on my s5 g870a and it's not likely I can get it.
I am not sure what the problem could be or whether I have to change some settings but my phones wifi as well as the Bluetooth don't work as expected.
I connect to the wifi at home, then if I go out i switch it off, when later in the evening I turn it on again, it doesn't auto connect (despite me clicking the auto-connect checkbox when putting the password) and I have to go back to settings click on the desired wifi and put the password again; this happens also when I restart my phone( it keeps asking me for my password)
The same goes with the bluetooth, on my s6 it would connect automatically to my car Bluetooth once I went through the initial settings, now even after the initial pair, it doesn't connect unless I put my bluetooth device on discovery mode again.
It's a rooted s8 with MAGISK,twrp installed on it.
I have tried to reset network and other setting,clear cache but no success.
any advice?

Hey,
I recently got a used Lenovo A7600-F tablet from my office because they weren't using it anyways.
Everything seems to work perfectly fine - except the wifi connection.
Code:
Model: Lenovo A7600-F
Android: 4.4.2 (no further update available for that model)
Kernel: 3.4.67
Build: A7600F_A442_000_029_150401_ROW
Here is the thing:
I disable/enable wifi
I click my home network and enter the password
Nothing happens for ~2 seconds
"Failed to connect to network" (no "connecting" or similar)
To make sure my WPA2 security isn't the problem, I made an unprotected hotspot on my phone. Absolutely identical problem.
One thing I noticed: The tablet is able to find all the networks around me and updates their signal strength in the list without any problems. As soon as I try to connect to one, it takes around 2 seconds until it says "Failed to connect to network". If I then try again, the message pops up instantly with no delay for all networks. From that moment on, the list also stops updating and can't be refreshed until I turn my wifi off and on again.
I downloaded "Wifi Analyzer" and I can see all the networks' strength values moving. I can close the app, do something else or go to standby and come back to see the values still updating. But as soon as I try to connect to a network, it will give that error again, stop updating the list in the wifi section and Wifi Analyzer will not be able to find any more signals. If I close that app and bring it back up now, the list of networks will remain empty. Same with the networklist on the wifi settings. Turning wifi off and on again resets the whole thing.
In short: My tablet sees all networks around me and updates them, but gives an error ("Failed to connect to network") as soon as I try to connect. Then no more wifi updates until i disable/enable it again.
Factory reset did not help, I let the battery drain and charged it back up - no success! I also tried an app called "Wifi Ruler", which was mentioned to fix a similar problem in a post I found on another forum. Connecting through that has exactly the same effect.
Does anybody have an idea about what is going wrong and what else I could try to fix this?
