[Q] Wifi doesn't work

Hi there,
Today I recognized that my wifi doesn't work. I can switch it on an there is also a massage that there is a wifi network available in the notification center. But if i open settings/wifi the phone writes no wifi networkes available.
My Z1c is rooted (KK .757) and locked bootloader.
Has anybody a idea how I can solve this problem?

This happens to me sometimes, after a restart works for me. May be next update may solve this problem

I've already restarted 3 times but doesn't help.

You can try: 1. restart your router
and 2. delete the settings for your network in your Z1C and make a new registration.
Is the problem solved?
I think no.1 will solve the problem. What a router do you? Many routers can do a automatic restart after flashing DD-WRT or Open WRT. These firmwares are available for the most routers.
greetings

What do you mean with 2.??
I've already tried to restart my router. But I'm pretty sure that the problem isn't the router because I can connect with other devices to the router.

go to settings - WLan and tap long time on your network and delete it.
It does not matter, that other devices can connect to your router.
I had the same problem with a TP-Link router after few days running. A restart helps only.

Delete the network doesn't help too.

Usually I find also the wifi networks of my neighbours. But now I don't find any wifi network.

For sure you have problem with your router since low cost routers is nothing than an s***t ! I had the same trouble with an low cost router until I come back with an good Dlink DSL2740B router 5 years ago, everything working flawlesly constantly ~5 years, no wifi isues! My sugestion to you is to buy an good home router! I have plan to bye this one http://www.dlink.com/us/en/home-solutions/connect/routers/dir-880l-ac1900-wifi-router which will work for sure perfectly next 5 years (probably more)!

I've solved the problem already. The problem wasn't the router.
I had to wipe DATA and then my WIFI worked again.
Then I tried to restore a backup what I've made befor but then wifi doesn't work any more.
So there was something buggy with my DATA..

WiFi strange problem pls help me

I have HTC m8 factory unlocked, updated to lollipop
My problem with the WiFi there is some apps can't to their servers
Despite of the mobile is connected to WiFi and there is Internet connection
Like what's up and 8 pool...
But if I used VPN.. Over WiFi The app will work 100%, and if I'm using 3g
All the apps work 100%
My software version is 5.0.1 and the sence very is 6
I did factory reset also same problem...
Again not all app works over WiFi... Some are working
P.s I tried different WiFi problem is presest
Pls help me with this strange probllem

I manged to solve the problem by changing the ip address from Dhcp to static.. But I Wana ask do I have to change the ip for each wifi I'm connecting to.. Thx

Now YouTube not working

probably a DNS issue.
On another forum for lollipop theres a known issue with a major internet provider and their DNS not playing well with the lollipop update. Changing DNS on the phone or in the router has helped people get past this. I first read it on a LG G4 forum. So maybe you are having a similar issue.

Nexus 5X can't find any wifi network

So I bought a Nexus 5X 2 days ago. When I first started the phone it was running Android 6.0.0 and it didn't have issues. But a update for 6.0.1 showed up and I downloaded it. And then the issues came. It cannot find any wifi network... The problem isn't from my network, because every other device finds my home network and all the neighbors network, but the 5X doesn't find any... I tried factory reset, network reset, cache reset, nothing helped. I even tried Android N beta and for a moment it fixed the issue, but this morning the wifi problem occurred again. I sign out from the N beta and through Mobile network it managed to download the last stable version(that's what google is calling it) - 6.0.1 and the problem was still there.. after some restarts of the phone and some factory resets, i thought the problem was gone, because it managed to find every wifi network in the area, but after i used the phone for 25-30 minutes, the wifi problem occurred again and ever since... So, is this a common issue with the phone, or the android 6.0.1, or is my phone a defected one? Should I go to the store and ask for a replacement? Or will the next phone do the same thing ?

Hi something similar happened to my 5X (6.0.1). It was able to find wifi network but I was not able to use internet even-though internet was working for other devices. I have restarted phone but my phone stuck in to WIFI Obtaining IP address...
I have restarted my router and problem resolved. Happened two times. Might be some bug in software.

I'm currently facing this very same issue, no WIFI networks are showing up. I've already flashed latest N preview with same results, funny thing is that this morning was working just fine. But I had to reboot the phone and now it won't detect any WIFI Network at all.
I'm starting to think I have a failed unit, but since I'm outside the "US" I can't send it back for warranty repair. So I'll just keep it and keep restarting until it's fixed again. This is really frustrating, never happened to me with any device I owned before.

Is it every wifi or just your wifi?
If it is just your wifi, try factory resetting your router after recording the settings, or try removing some entries that my be using NVRAM.
I've seen cases where the router runs out of NVRAM to record the DHCP entries and that causes connection issues. It doesn't show up for other devicdes because their entries are already stored in NVRAM. It is just the incremental new device you add that triggers the problem, so you naturally think the problem is with the new device since all your other devices work with the router.

my solution for wifi not found/working
i´ve upgraded from the nexus 5 to 5x.
i had a really weird issue with my wifi.
only found my wifi when i was not in airplanemode. so i read 1000 of articles about the wifi of the n5x.
just the standard blabla. so i did my own research
while my n5 and my n7 + 2 laptops had never issues my new 5x didnt find my wifi. i really thought it was an hw-issue. but it wasnt.
i am using a fritzbox router. newest update, made a reboot, rebooted phone. nothing happened.
then i checked my wifi channels, set it to manually and instantly found my wifi. i really never expected that the channel got such a big influence. may be the latest update brought a bug for the wifi channels or the hw is just not capable of some channels, dunno. but this is what helped me and it was nowhere mentioned in any forum.
tl;dr
try to change your wifi channel of the router.
edit: btw i found the 5ghz while the 2,4ghz wifi didnt work. but i wanted the 2,4ghz wifi to work because of the short range of my 5ghz wifi.
atm i am on channel 8 and i got no problems with the 2,4ghz wifi network

I don't know about Europe, but usually in the US we only use channels 1,6,11 to prevent overlap.
This is because there is overlap in the channels so you can't really use the in between channels due to too much interference. If you are the only wifi transmission in your area it is fine to use any channel, but if there are others and they are using standard channels for no overlap/interference and you are using in-between channels, your signals are probably going to interfere with each other.
When everyone is using the set channels, then they can negotiate properly and everything works better. With overlapping frequency bands, the negotiation doesn't work well because your signal sometimes looks like noise to the other device.

Hi, thanks for your help but unfortunately it's every wifi... it just hangs on "Searching for Wi-Fi Network..." and stays there...
I already talked with LG and they asked me to send the unit for repair, but I'm no in the US anymore (I was for a short time of period and that's when I bought this phone). So that would not be an option, right now I'm only using 4G and trying to measure it, lol
Just another question, do you guys think I could use a WIFI external dongle through USB OTG? Could that be possible on the Nexus 5X?
Thanks for your help! :good::good:

Hi, thanks for the suggestion but the problem I'm facing it's with every wifi network around, not only mine.
I guess unit is defective, but could a simple reboot trigger this kind of behavior? This is strange, never happened on any device I've owned before. :crying:

Hotspot Connectivity Problem

Guys i'm having a problem with Hotspot where i can't have anything connected to it for a prolonged time... I tried both 5 and 2.4Ghz but my Moto X4 and my friend's S10+ can't stay connected to it for even a second... It only works after i restart the note 8 pro a couple of times... And even then it disconnects from time to time... Any of you having the same problem?
Edit: I also tried it on two Laptops.. Still the same issue. Sometimes it says the password in incorrect and try again. But i connect with the QR code so that can't be true...

Possible interruption from another WiFi or other signals around your area. Try testing in a isolated are or use other places. It might be the WiFi channels collided.

I checked on another phone... This seems to be the issue but i will update on this once i get home. I'm almost sure i had the same issue at home.

Yup. That seems to be the issue.. thanks for clearing that up. However, does that mean I'm never going to be able to use hotspot at work.. or is there someway i can play around with the settings and fix this?

My phone is redmi note pro 8 , I am unable to connect my hotspot to any other device. I tried restarting and switching off my phone, also switched off other hotpot and wifi networks and tried both 2.4 and 5Ghz but didn't work.

for my device's hotspot there is no problem for connectivity but there is a bug where I can't see who is connected to my hotspot and only shows the number of connected devices which means I can't block users from my hotspot..
my advice try to flash again with the mi flash tool in fastboot mode.
to do so it must have unlocked the bootloader

I have this same problem for my redmi note 8 pro how to fix it

Question 5ghz WiFi Issue

I bought a Poco F4 (global version, xiaomi.eu 14.0.5.0) about one month ago, I haven't had any issues with it whatsoever, save for the fact that it suddenly won't detect my 5ghz WiFi networks (my main router + a repeater) - and I'm not even sure if this is an issue with the phone itself.
I'm coming from a Samsung Galaxy S20 FE, which was known to have this issue, but to have this happen on 2 different phones is really weird. If I recall correctly this issue started to affect me after I changed my ISP.
The only ways I have to detect the networks again is to go the debug mode and use the WiFi Sniffer Test Tool or reboot the phone, which was more or less the same thing I had to do on the S20 FE (I had to go turn on airplane mode try updating the firmware via debug mode).
What I've tried so far to solve this issue:
1. Changing the channel of the 5ghz WiFi
2. Changing the bandwith from 20/40/80 to 20/40
3. Setting "Use Device Mac" on the phone's network settings.
4. Turning off WiFi Scan Throttle
5. Changing the bandwith to 20
All of the above methods, save for the last one, did not work. And while it does work, it limits the speed of my internet to bellow 100mbps.
The issue is not related to the WiFi coverage as well since it only happened when I'm on my own room, which is where my router is located.
I don't know if I can detect other networks apart from my own since even when they 5ghz detection is working I can't find any of my neighbors' networks. I'm unable to create a 5ghz hotspot on my S20 FE or on my old Redmi Note 9S for some reason.
I'm at a loss on what to do, it happens on both stock and xiaomi.eu, at least and at most once per day.
If anyone else is facing the same issue or has any suggestion on what I should try next please let me know.
Thanks in advance.

I have no problems with 5G Wifi on xiaomi.eu rom
All the time 300Mbit/s
Buy Wifi6 router

This doesn't look like a problem with the phone (s).
Try connecting to another router to see if you have the same problem.

Are they on any specific channel/bandwith?
Both of mine are WiFi 5 though.
Thanks for the reply.

Thank you for your input. I'll try to turn on my old router when the issue happens again. I find it odd that the issue affects both my main router and the one I use as a repeater, but everytime I made any slight change on the main router, the other one's signal almost immediately disappears to apply the changes as well, so it's probably that.

mode: 802.11a/n/ac/ax
channel: 48
bandwith :80MHz
I'm using Tenda TX3 Wifi6 router.
No issues at all. Great internet speed on wifi connection.

The problem is indeed with your router + repeater setup. Your phones are fine.

Thank you! I'm almost certain that the issue is that the bandwith isn't fixed at 80mhz, it's 20/40/80mhz, and when I had the bandwith set to 20mhz I didn't had the issue.

Thank you! It's probably related to the bandwith. I was able to turn on an old router and my phone was able to detect the 5ghz network after the bug happened and my router + repeater signal was missing.

Have you tried resetting your router to the default settings? Or maybe set a specific IP address on your phone in your home network? As said above, it is a setup issue of your network most probably..
