@azulpiscina, you have to click the "Mount R/W" button at the top right of root explorer screen before you can edit files.

Trying, back in a minute with feedback.
thanks!

This ended up not working for me either. I have had this issue with this phone and others and it seems to come and go, raising it's ugly head again when I went with CM7.
I had a D-Link DIR 655 router and last night I replaced it with a TL-WR1043ND and so far the issue is gone. Signal strength is much better too.

Ive had no problem

Ive had no problem whatsoever with wifi on any cm7-rom ive installed.
Ive had rc1 and many nightlys installed and never had any issues with wifi.
My router is a Linksys wrt320n with dd-wrt software.

It didn't come with it but I flashed the new router with dd-wrt. I have not had any wifi issues since.
I was reading on the dd-wrt wiki about the N specs and discovered there is a setting in the old router that may fix the issue and also explains why some people have issues and some don't.

I installed CM rc 1.5 and I have a Linksys WRT54G at work (with dd-wrt) and one at home (original software), and i'm having this wifi disconnect issue in both.
I have 2 defys, the other running 2.2 and it's amazing to see the difference in the signal strength of the two ROMs running side by side.
I just tried deleting the file /data/misc/wifi/wpa_supplicant.conf and reboot (from this thread: http://forum.xda-developers.com/showthread.php?t=1161460&highlight=cm+wifi) in the last 10 minutes and so far so good, but it didn't seem to fix it for someone else in that thread in the long run. I'll report back here if it fixes it.
Update: That tip above didn't work, but now I'm using 110927 nightly and I don't see the disconnect issue anymore, and the weak signal seems to be gone too.

I also had wifi problems, always disconnecting. I found in the official motorola forums someone saying you should search in the router settings for an option called wmm or wme (windows media extension) and deactavate it. also use tkip instead of aes. im running cm7 rc 1.5 with a dlink dir 655 router. it solved my problem. didn't have any dissconects the last days.
hope this helps someone

Problem is, there are wifi issues in CM (at least for some people, like me). I don't have any problems in 2.2, with the same routers I always connect to. So I would guess we need to find what could be changed in CM to fix this issue, although I understand that changes in the routers can alleviate the issue.

Anyone knows where's the cfg of the wireless strenght icon on the top bar? I wanna change the value of the 4 stages.

i agreed with bra2006. it should be fixed in cm7, and not expecting any everyday users to muck around with their modem settings to get around it.
if some roms don't have problem, why should cm7? surely they can compare and work out why cm7 has problems while others don't.

I also have the same problem, with RC1 was ok, when I put RC1.5 began to disconnect the wifi

if you use WiFi usually.....it saves battery, and keeps WiFi connected until you disconnect it....
and does not toggle to your 3G/4G Mobile Radio when in sleep mode...which then has to toggle WiFi on again.....
It might work!!

omg... i have the problem too. i was using bionic cow. last night i flashed the black notes but later i restored bionic cow and the settings using cwm. and wifi totally didnt work. oh no

I've just started getting the same problem since updating to the latest stock update. Thing is just after I also changed my router so not 100% sure if it's the phone or the router. My WiFi is ok but after I've not used it for a while I have to stop and start it again for it to work (the phone not the router).
When you say it was the routers problem what did you change in your settings? I've looked into mine and can't see anything that would cause it to disconnect the phone and my phone is set to 'never' disconnect in sleep policy.

i suppose this happened to me quite recently.
try having your network either on wcdma ONLY or GSM ONLY.

Thanks for the reply but I've sent my phone back to Samsung for a cleaning as it had dirt collecting under the screen. I mentioned on the return form about the Wifi so if they get back to me on that I'll post what they said.

Got my phone back from Samsung. Have to say great service. Sent on Tuesday and back repaired on Saturday. The WiFi problem was also sorted. They just put a note in saying 'We've installed the latest approved software as part of the standard repair service'. Funny as I thought I had updated to the latest just a few days before sending it off. Phone reads:
Android Version: 2.3.6
Baseband Version: I8150XXKL3
Kernal Version: [email protected]#3
Build Number: GINGEREAD.XXLA2
I'm in the UK so if anyone else is having this problem update to this and hopefully it should fix it.

WiFi Connection problem. ( Network Disabled. Poor connection)

The weird part is it says "Network Disabled. Poor connection." but the bar is strong. It has always worked up until the last 24 hours. No god damn google-ing was helping. It is set to wpa/wpa2 PSK.
What the hell is wrong with it. The 4glte works. I haven't downloaded anything obscure.
Provider Telus.

Wow, I now have the exact same problem with my SGS3 (international version without LTE). I already tried "forget this network" on my phone and "delete this device" on my router but it still wouldn't connect.
I installed the official JB update a couple of days ago. Never had that problem before.
Edit:
I could fix it by disabling DHCP and instead assigning it a static IP in my network. Though it is still a bug because if I'm in someone else's network (e.g. Starbucks) I usually wouldn't be able to use this solution.

Okay, it stopped working the next day and now everything I try, I can't get WiFi to work.
****ing piece of **** phone. Since the official Jelly Bean-Update (my phone is not rooted and no custom rom or whatever) several things stopped working. My ****ing Google Calendar just won't sync anymore (says "sync is currently experiencing problems, will be back shortly" for 2 weeks now), ****ing WiFi stopped working. I'm really pissed right now, mostly because I didn't customize my phone for exactly those reasons!!!

Honestly, what were you expecting? touchwiz is notoriously known for being absolute trash. None of the issues you've brought up occur on custom ROMs. Bite the bullet and flash one already.

My solution for "Network disabled. Poor connection" problem.
I had exactly the same problem today (SII, ANdroid 4.1.2 - Samsung leaked) but the history was a bit different. After the flashing all worked fine for several days. Today I upgraded my WiFi router with the new firmware (before I used the 5 years old one) and on my Droid the problem occurs. What is important, I got 3 devices in the home network: my Samsung Galaxy S II I mentioned, and 2 others - HTC Desire HD and Galaxy Ace - both with tje Android 2*. WHat was strande, only HTC worked withut any problems, both - Galaxy and Ace stopped connecting to WiFi.
I read a lot of posts, i undersand that the available solutions are: static IP (not acceptable, I need to connect to different WiFI networks every day) or rooting phone and clearing DHCP configuration on the phone (not available without root, as in my case). But - because everything worked ok before, without any changes on the phones (!) and as I read in the posts the problem is network-related, I decided to find the issue in the router configuration. So I cleaned the conf. of the router (reset to thefactory default settings), removed the information about my network from the phones, connected my phone to the "Clean" unprotected WiFi (default WiFi set-up after the reset), and then step-by-step added more security configuration on my router. First - changing the WiFi SID name, through the wireless mode (AP), then network mode - from B to Mixed, and then security modes WEP, WPA, WPA2 and algorithms: TKIP, TKIP+AEP. After every change on the router (several router restarts needed unfortunately) i tried to connect my phone to the WiFi. Finally I added the MAC filter. And... everything works OK! :laugh:
I propose to test the same solution. In my opinion the phone will connect without any problems to the unsecured WiFi, then one can find which step, which area of the config cause the problem - if it is solved when setting the mixed network (B/G) or maybe some of the security algorithms are not accepted.
I know that in fact it is not the fastest solution, but in my case the problem was solved - I got the same security level and settings as before when I had this error! Probably the changing settings of the connection which must be aplied by Android, do quite big 'revolution' in the DHCP conf. files of the phone, and the result is the same as after clearing the folders after rooting.
I hope my solution could be helpful!

No need, mine works fine...

I have exactly the same problem. Started right after the 4.1.2 update (SGS3 international). Unable to connect to any secured WiFi. Always the same: connecting -> authenticating -> obtaining IP address -> disabled (and a popup about poor connection).
Sometimes it does connect if I reboot or first reboot after factory reset.
Tried about 4 different routers. Factory defaults. Still the same.
I guess it's time for an unofficial ROM...

Stock JB ROM? Router model? 2.4 or 5Ghz?

I had this exact same problem, I had 4.1.1 and I odin flashed to 4.0.4 thinking it was the JB update. I found out that my Wifi password was off by 1 number and instead of the phone telling me my password was wrong it would throw that error at me. As soon as I double/triple checked my password and entered the correct one, my phone has been working fine ever since. I am on stock 4.1.1 JB.

Did anyone find a solution to the Wifi Problem on 4.1.2?
Regards

I think i found a fix, for some!

Some routers can broadcast on both frequencies simultaneously with different SSID's. I know newer Netgear routers do this.

notes on my exact situation
-wifi works fine on many open networks and private networks for both myself and my gf (both using galaxy s3 phones)
-the specific network is a private network at a business (my gf is the owner of the business so we have access to the router and its settings)
-we have both previously connected to this network before without any issue.
today neither of us could connect to this network. we restarted our phones, the router, "forgot" the network, and eventually gave up.
This is very frustrating as we both spend a good amount of time in the business (coffee shop) and it seems that no one else has connection issues, not other phones, not laptops or tablets, not anyone else. Both of our galaxy s3's just keep coming up empty on this one network.

Help!
I have the same problem after root my i9500 with CF-Autoroot on 4.3.
Already tried everithing but after some time from root it lost connection and can't connect again, even on other router.
With 4.2 always worked fine. But now, if I do the root process the wifi works only for 5 minutes.
It start with the first 4.3 update, but even now with the last 4.3 I9500XXUEMJ9 I can't root.
The "Network Disabled. Poor connection" is the only problem, everithing works fine. The root is ok. Knox freezed.
But now I have to flash the stock firmware again to get wifi working. That is the only solution (remove root) until now.
Any help?

Bad wi-fi performance

Hi guys!
I'm having some issues with the wi fi of my N5X.
The signal is always good and the icon on the notification bar is full.
But when I try to download something (for example from the Play Store) the speed is sometimes around 30/50 Kbps and sometimes 3 Mbps
With the 4G is going well...
I also tried to test with the speedtest app (screenshot attached); as u can see in the graphic he started with a lower speed then the last seconds.
I attach the same test done by an iPhone 6.

If we compare the 2 results:

Dowload
N5X started with low speed until he reached 26,58 Mbps. / iPhone: "flat" graphic at 28,67 Mbps.
Upload
N5X stayed at 0 Mbps until the last one second. / iPhone: not a perfect graphic but he reached 3,13 Mbps.
So: sorry for this boring thread but i need some suggestions.. What can I try?

It might be the ROM you are using. It could even well be a faulty radio.

The radio could be going bad you could try and flash a different radio. Try going back to stock everything and then checking to see if the results are the same. If they are I would lean towards the radio going bad.

Same problem here. Upload is tragic and WiFi connection is unstable.
On the other devices without problem.

Didn't anybody try if 6.0.1 solved that problem?

Any phone can have issues with any WiFi network and you need to troubleshoot. Google will not release an update that fixes your router's compatibility issues.
"WiFi works on all your other devices" only tells us that your WiFi is enabled and working. That's a great starting point, but that's all it is.
Each device is unique. Each WiFi network is unique. Unique devices can have issues with unique WiFi networks.
I'd suggest doing some searches on general WiFi issues (don't even specify 5x in the search) and troubleshoot steps to resolve them. Some basics to get you started:
- Reboot the router.
- Update the router firmware.
- Disable IPV6 on the router
- Forget the device's WiFi networks and readd them
- Set the device to use either 2.4Ghz or 5Ghz instead of Automatic
- Etc.

All thoses things, I speak for all, we already did them. It's the basic first things to try.
Thanks to refresh our memory anyway!
Personnaly, I asked for a exchange of the device, I don't want to (don't have to) search some fix, flash or tips on a 2 days fresh new device! There is clearly a bug here, we all got the same problem on a stable wifi router. So problem is in the phone.

I would be shocked if everyone had tried even those basic steps. People assume it's a unique issue with their device but this is actually a common issue with any device and various home networks. It's not the phone manufacturer's job to ensure compatibility with every router ever made and there are thousands (millions?) of them.
Check any device in any device forum and you will find people with similar WiFi issues. You just got unlucky this time.
"Stable WiFi router" wouldn't have issues with your Nexus 5x. Unless you think your Nexus 5x is defective then by all means return it. Or perhaps you think every Nexus 5x has WiFi issues?
BTW this was the very first reply in this thread and he was right on the money:

FYI, things doesn't work in the world like the USA.
Here in France we don't buy router, they are given free with our plan and are multi function: unlimited TV, Internet, phone, etc...
Updates are automatically send by the providers. I checked mine and it's up to date. And I'm downloading at 10ko/s on the nexus 5x.
It's been more than 30 minutes it's trying to get the 6.0.1 update (and it's not finished, it's at 20%...)
Yesterday I noticed for a single file, download started at 400ko/s to fall at 10ko/s, then up again to 200, down to 15, etc....really unusable. 15 minutes later, I had to cancel (little 30mo file) I got bored, so i downloaded it on the nexus 4 in 5 seconds and transfer it to the 5x. What a mess.

Hi Guys!
As i said in my first post i still have unstable wi fi performance.
What i noticed is that the download problems are nothing in front of the upload problems.
Usually my device download like a diesel car (?): it starts at 20Kbps for 1min... Then he get better with 100/200 and sometimes 500Kbps.
But the upload!!! It starts at 100Kbps until he goes at 0Kbps for a lot of time!
For who asked if 6.0.1 solved this: nope.
I thought the same thing but now I'm running that build. Same issues.
I still don't understand if it's an hardware problem or "just" a bug.

People that have WiFi issues, did you try to go to another public place or friend's house to try your phone there and download few things and see?

Hi Charkatak, thanks for your reply.
Yes of course:
Personally I've tried with 5 different wi-fi hot spot / routers: My home / Office / My girlfriend house ecc... In all of my tests i also used my iPhone which always gave me perfect performance.
But with the N5X I had always the same results: some times the download is a bit better... But the upload during the speed test starts from 1/2Mbps for the firsts 2 seconds and then it go at 0Mbps.
This thing is making me crazy! But I prefer to find a solution instead contact google and staying without smartphone for weeks..

FYI - I am at work now and did speed test: Down 136 Mbps & Up 101.44, but that is just a quick test.
If that is the case, then there could be something...I doubt it is the phone, but most likely it is the OS.
I have noticed couple of times when I download something, game for example:
1) I stay on the same screen while downloading and making sure that screen doesn't sleep, then download is fast.
2) Other times, I would just press "back" button, to go to home screen or do something else, then in rare cases, the download would seem slow and when I go back to the download progress, it really is slow.
You can try step 1 and see what happens. Looks like when phone is downloading something and we leave the screen, then the process is in the background, that is probably when OS applies some battery-saving technology.

Thanks again Charkatak.
Yes I noticed the same on my Android phones. Not only on this 5X, but also in the previous devices I had.
But that isn't the point, cuz in all of my tests my screen was always on, and the only app opened was the speed test app (or the play store).
And the bad thing is that I never had those bad performances on my speed tests with the other phones (iPhone or Android)...
That's why I'm so disappointed about this WiFi module...

Are you always trying to download something from Play Store? Have you tried to download a file using Chrome browser?

Yes. Download from chrome it's "random".
Sometimes it goes at 100/300kbps (so slow anyway) and sometimes 40/50kbps....
One ore two times is happened to download from chrome at 1/2 Mbps..
That's why I'm confused: i can't understand if it's rly a SW problem or maybe it's an HW issue..

Weird WiFi issue in some apps after updating to Android Pie

Two days ago I got Android Pie update and recently I noticed some issues with following apps:
YouTube
Nintendo Switch Online
System update
Signal Private Messenger (well, this works sometimes...)
The issue is that those apps stoped working on WiFi. They work fine when I use mobile data (cellular connection) but simply refuse to connect when I use WiFi. Other apps work just fine (including web browser - Chrome).
What I have already tried:
Forgetting WiFi network and registering it again
Completely resetting network settings
Restarting phone
Cleared app data and cache for those problematic apps
Reinstalled the apps that can be reinstalled
None of the above helped fix the problem... Phone has stock Android straight from Xiaomi, I didn't mangled with it in any way.

For my WiFi is broken since Pie update.
In my case, Twitter and Twitch app refuse to load too. Even Google Photos wont sync, it says "waiting for WiFi connection" besides WLAN is in ON and working.
Cant access certain sites.
Funny thing is that, for eg twitch app won't work, while in the same time mobile version of twitch works perfectly fine

Good to know, I was thinking about doing that...
It is really hard to do something about it. I played around with DNS settings (they added that in Pie) but even changing DNS didn't seem to resolve the issue although YouTube started to work (for now at least, but I don't think that has anything to do with DNS changes). Other apps from my list are still broken...

Same issue for me when I was on stock Pie. I don't know why, but using a VPN fixes the issue for me if this can help

Im thinking about flashing CAF kernel https://forum.xda-developers.com/mi-a2-lite/development/caf-caf-kernel-mi-a2-lite-daisy-t3880135
It is using different WLAN driver. But this requires unlocked bootloader, and this will cause another data wipe... Also there is no certainty that this will fix the problem.
Have you tried connect to another WiFi? Maybe this is releted to ipv6/MAC adress/DNS. Router/Access point issue?

From what I see phones gets IPv4 address BUT it has two DNS addresses. One is IPv6 and the other one is IPv4. I think both point to my router. I haven't changed anything in router configuration and WiFi worked fine on Oreo... I will try different WiFi network tomorrow at work

Do you have bluetooth on? I found out that when m bluetooth is on, WiFi conwction ia really bad. This os only on pie.
Check out my thread. https://forum.xda-developers.com/mi-a2-lite/help/bluetooth-wifi-conflict-pie-update-t3883829

So, I tested my phone on my office WiFi and surprisingly apps that I mentioned on my list worked. It seems that Android Pie on my Mi A2 Lite doesn't work well with IPv6 WiFi networks. Office WiFi is IPv4 only and assigns two IPv4 DNS addresses while my home WiFi assigns two addresses as well, but one of them is IPv6. I will try to recofigure my home network and see if that will help (I guess @ShadyTurtle334 mentioned something about possible IPv6 problems)

Yep, switching network to IPv4 only works like a charm. Android Pie must have broken something because on Oreo everything was fine... Does Xiaomi has some sort of issue tracker?

Maybe post your findings here https://en.miui.com/forum-205-1.html
Yes, it is MIUI forum, but our A2 Lite is listed there, so i cant imagine better place.
Also, you should have app for that, i am not sure how is called in your language (orange icon with smiley emoticon?)
It seems that my Router/AP doesnt have options for ip configuration, maybe i am blind.
edit1; There are similar threads already. https://en.miui.com/thread-5119175-1-1.html
edit2; Forced IPv4 in AP settings, now WiFI works like a charm!!

WIFI Problem after PIE update
Hi, Irecently updated my phone to Android 9.
My phone model is:MI A2 LITE
There is a problem with WIFI. Some applications such as Instagram, google play game or Telegram cant use internet.
Somehow something like Firewall stop them, But other applications such as web browser,play store,... are connected to internet.
When I am using my SIM CARD data there isn't this peoblem.
I dont think the problem would relate to modem or wifi , because other mobile models dont have this problem and theyre working without any interruption.
Thank you to pay attention. Please say me how to provide this problem.

up !!

it's off

The only way to fix network problems is to flash again to 9.6.4.0 Oreo and stick with it or 10.0.2.0 and OTA update to 10.0.3.0. Other versions seems to have corrupted modem.img and mess with SIM cards slots (swaps places and/or one of the SIM isn't working). Just check my other posts.

I never had problems after flashing 10.0.3.0 and I did it several times. There is no corrupted modem.img or something like that. These problems may occur when you downgrade from Pie to Oreo, that's why Xiaomi warned about it.

Well no. Issues with the network started after OTA update to 9.6.11.0 thus the only way was to update further to Pie or to downgrade. I updated but issues persisted so the only way was to downgrade and reprogram sim slots.
All of this may be because of different parts' vendors so not all of the A2 Lite react the same, or you just didn't notice, because you don't use two sim cards at a time or/and bt, wifi & location at the same time. It may be max 1 mbit you can achieve on the wifi but for a phone is a decent speed. Personally I can't stand it, so I dirty flash 10.0.2.0 and now everything work as it should.
This is about network problems on Pie. So either you can't read or just stupidly assumed that everyone had their devices downgraded, then updated and thus network issues. And if you weren't be so lazy and read further, you would have known that modem.img from Oreo can solve network issues.

@thorin0815 And why would you flash several times if there were no problems at all? Reseting yeah to start fresh but flashing means something's wrong.
@wenna.speedy Turning off & on some features or messing with your modem settings while other devices work properly is not a solution.
