[Q] Can't turn wifi or bluetooth on - General Questions and Answers

Hi so i've been searching and re-searching over and over to fin what is going on but i can't find a solution to my problem, turns out that mi wifi (and bluetooth) can't turn on, funny thing is, i have to reset several times in order to make them work but it will last just a few minutes, although i have notice that when i make it work and stay connected on a strong wifi signal sometimes it wont deactivate but not always this is getting frustating, another thing is that when i do a factory reset or install a new rom rather stock or cm or any variation it will work but just for a minutes as well.... any idea what it could cause this and how to fix it??

Frustrating Wifi problems

It seems like wifi on my phone just won't cooperate with me.
The problem's never the same but the general concept is the same. Either my wifi doesn't turn on, or it'll turn itself off after some time. Sometimes I turn on wifi in comm manager and I'll get the loading thing, but then it doesn't turn on.
Other times, it'll turn on only to be instantly turned off again.
Other times it'll turn on. I'll start surfing the web (or doing nothing for that matter) and it'll be turned off again!
Sometimes it'll turn on, work fine, and then I'd lock my phone and turn off the screen for a while. Afterwards, I turn on my phone again and it's turned off again. It was on before I turned off the screen (and it should stay on.. it did when I first got my phone).
I recently hard reset and flashed to Energy Rom, Mercury. The problem persists. I guess this means it's a hardware issue right? I've checked many settings (including all of the settings in advanced config) and it seems like wifi isn't acting as it should..
Anyone have any ideas?
hard reset, flash new radio/rom

thats not going to work he said that he just flashed the newest mercury rom and that means he has probably got a good radio too . unless its just the radio .
other than that i don't know what to tell you about wifi other than i don';t use it much .
the rom works fine and the radio doesn't affect wi-fi. there are some settings that disable wi-fi after a period of no use. it could be that. only reason that would occur while you're actually using it tho would be that it was using your data connection and not wi-fi the whole time so wi-fi stayed inactive and decided to shut off. check your wi-fi settings.
I made sure that I disabled data connections (since I don't have a data plan. I cannot connect to the internet if I do not have wifi on).
I'm pretty convinced this is a hardware issue.. Looking at my wifi settings, there's no reason why it should turn off, and the only thing I noticed was that in advanced config, it's set to disconnect wifi after 2 mins of inactivity. I often get disconnected from wifi like 4 seconds after turning it on (and often while I'm trying to load a page in opera too).

[Q] Enabling Wi-Fi Crashes HD7

My HD7 worked without issue from the beginning of the year til around a month ago.
All of a sudden, my WiFi became extremely unreliable, sometimes taking an overly long time to recognise or connect to an obvious access point, sometimes finding none at all.
After I do manage to connect wirelessly, I see no speed increase in data transfer to suggest that the phone is even using the wireless link. Web pages sometimes load slower than over 3G. I had read that HD7s have trouble using certain WiFi protocols and adjusted accordingly, but the workaround was to no avail.
Additionally, once WiFi has been selected, I cannot switch it off. I am 'locked out' of the WiFi settings page. When I tap it in the menu it responds as if I've nudged it but it cannot load. The only solution is to remove the battery. On occasion, this stuck WiFi has also caused the capacitive buttons, camera and power switch to become inactive. Curiously, touch screen function seems unaffected.
I thought maybe this issue was tied to corrupt settings with my hub, but changing SSID / WEP key etc etc on my router hasn't fixed the problem, and connection to other open WiFi signals jam the phone just as badly.
I upgraded to Mango in the hope that a fresh OS update may 'rejig' my wireless settings into working, but again, no joy.
Anyone experienced anything similar? My final options seem to be factory reset the handset to see if that solves the issue, or return the handset to O2. (Both involve losing all my data, game saves, application data AND the recently delisted SW: Battle for Hoth permanently.)
Anyone got any other thoughts?
*EDIT* After a bit more research, I found that even when the phone has connected to a WiFi source, by turning Operator Data Service off, you can see that the WiFi service is in fact not doing anything.
I braved a factory reset, managed to whack WiFi on no problem, browser ran at appropriate speed, then everything crashed as per usual, I couldn't connect to the marketplace and had to pull the battery in order to use any of the capacitive buttons. I guess it was a hardware issue individual to my phone after all.
Guess I'll give O2 a ring sometime soon to sort a replacement. Not looking forward to losing all my game progress though it has to be said.
bro i m having the same exact problem havent find any solution yet i even tried to copy and replace the wifi files from another clean htc hd7 but useless when i upgraded to 7740 the wifi worked perfectly for 1 night only then at the morning it stopped working, everything else works great. my theory says that its not a hardware problem cz i used internet sharing which uses the wifi adapter (if i m right) so its a software I GUESS

I had the same problem as well, couldn't connect, got to the point where even the power button stopped responding. Hard resets would only help for a short time and enabling WIFI would never connect right and eventually get me back to the same problem. I then got a replacement device, but it's not much better, I still can't connect to any WIFI, but at least it's not freezing up on me. My solution thus far has been just to avoid turning on WIFI if at all possible, but it's far from a perfect workaround. I'm guessing it's the HTC WIFI driver that's got issues.
i got similar problem.. send phone to service problem was "circut board"
replaced working fine...
when i was using wifi my phone was freezing some menus stop working and i have to remove battery

Nexus 5 WiFi Crashing Phone

Hi all. I have a weird issue that after Googling it doesn't seem anyone else has had.
The issue started earlier today, in the morning. I was using my phone on the WiFi and it was working phone, then my phone crashed, restarted itself.
I noticed it wasn't connected to the WiFi, went to the WiFi settings and where it usually says the list of networks it said "Turning on WiFi" and the slider at the top was greyed out so I couldn't turn it off.
I tried airplane mode and that didn't help. But the phone was working fine on my mobile data so restarted.
Now the weirder part starts. I basically have an issue where, if I turn on the WiFi, my phone crashes, or doesn't act like it's turning the WiFi on.
Even going Settings and then pressing on the WiFi option freezes the phone.
The problem started when I was still using 4.4.4 however since the problem developed I've used my mobile data to download the updates and now have 5.1.1 I think.
The problem persists even after updating to the most recent version and doing a factory restore. The phone is currently completely stock with nothing downloaded on to it. All I did is go through the first time setup for the device.
The WiFi currently is off, and the phone is working however it won't connect to my data, it has the signal bars and then an ! instead of a 4G icon.
If I try to turn the WiFi on it crashes the phone.
The phone is still under warranty so I plan on contacting LG on Monday however it's currently 3:34 AM on a Sunday so I have a day until I can call them and was hoping for a solution in that time.
Thanks in advance. I have the phone to hand so anything you want me to test I'm able to.
There is some information I didn't type as I don't know what is important was trying to avoid a wall of text so if you have any more questions I'll answer I best I can.
Thanks for reading, I hope you can help!

Wifi keeps disconnecting?

Hey, guys I just got my Pixel 2.
I connected it wifi but it keeps losing it. Only if I reset my router it will keep the connection for a while, but somehow when
I get to work or in the morning the same issue appears again. It connects but when I go to an app which requires wifi it drops.
I tried to change the channel but didn't work as well.
Restarting the phone won't help either. I also don't want to factory reset it since I want to keep all my data etc. I don't want to go all that bs.
Maybe I should have stuck with a new iPhone after all. Sorry for that comment, but I'm really frustrated
I don't want to give it back or some ****, I just want to fix it easily so I can move on. I hope I get some advice here.

this can help:
phone ::: Go to setting > wifi > advance > If there is Freq option then change it to 2.4Ghz
router (in case no option on phone) ::: go to Wifi setting of your router and disable 5Ghz. I can help more If I know model of your wifi router
:good:
I'm having the same exact problem as OP. I thought for a second I wrote the post. Would love to see if there's a solution. I don't see the option to change frequency in wifi settings. And this issue for me occurs on different WiFi networks.. so it's not just one router. Ugh!
Exactly the same issue here, which is what has lead me to this thread. It often happens that my phone switches to mobile data suddenly while working absolutely fine on Wi-Fi. I have tried almost every basic solution but condition remains the same. Also during that time it stop showing me my (saved) Wi-Fi in the Wi-Fi network available, while at the same time my same Wi-Fi is connected to all the other devices in my house. This needs a fix.
still no fix

Is Bluetooth on? This is what is causing my WiFi to be very unstable......

WiFi connect/disconnect loop after MIUI 11.0.1 update

I updated a family members Redmi 6 to MIUI 11 and it's developed a WiFi issue. that I can't seem to fix.
Basically, I turn on WiFi and it connects like normal but then several seconds later it will disconnect, but then it'll immediately reconnect as normal. It will do this connect then disconnect in a loop without ever staying connected.
I've restarted the phone, reset the WiFi settings on the phone then rebooted and reset my router all with no luck.
My Moto G7 Plus along with a laptop, several google home devices and a few other WiFi stuff all work just fine so I can't seem to figure out what's wrong.
The only thing I've not done yet is a full phone reset, I would need to do a backup before I try that but not sure what is the best way to do it.
Here is a video of what my issue is.
I've also posted on the MI community but hoping someone here can help me out.
