wifi suddenly wont connect to specific wifi anymore - Xiaomi Mi A1 Questions & Answers

I wokeup this morning and noticed my mia1 wasn't connected to wifi anymore.
when i went to settings->wifi-> saved networks i could see the target ssid
no matter what i did i couldn't get it to connect to the desired wifi, but it has no problems connecting to other wifi networks.
things i tried
- rebooting phone
- deleting ssid and readding
- rebooting router
- hiding/unhiding ssid in router settings
- toggle airplane mode
- toggle wifi
- connect to 2.4 and 5ghz. both failed.
Anybody have any ideas what the issue might be and how to resolve?

Do other devices connect to that particular wifi? If not, that means there is something wrong with the router, if they connect, there is something wrong with your phone... And I really don't know how to help you, because you listed all the things I would've tried

You could try changing the wifi PW (router setup) to something short and without special characters.
Just to eliminate compatibility issues...

WTF!?!? Wifi won't connect to home network

I am trying to connect to home wifi which I have done in the past but it is not connecting. I am getting:
"Obtaining IP Address..." "Disconnected" and that just loops
I am on my laptop connected to the same wifi network, I got on my wife's Vibrant and connected to the wifi, what is up w/ my phone?
What suggestions do you have, this is what I tried, I was even able to connect to neighbors open network:
restart phone, turn off, "forget network", toggle wifi on/off, plug in usb,
Your lease probably expired. Did you try restarting your router?
Never had to do that in the past, but I'll try it. Guess i'll go to sleep now, maybe it fixes itself tomorrow, if not, I'll restart the router and post back the results
what type of router have you got? I have the same problem with a Zyxel router. Can't find a solution to it. Google shows lots of problems with Zyxel and HTC.
If you find a solution to your problem can you post back so I can try it out. Cheers.
MAC address filtering enabled?
Yea I also had that issue but only on cyan base roms. Sense and MIUI never had that issue. Well anyways I fixed this by flashing a new rom

Yeah I had the same problem, I just rebooted my router and it worked perfectly after that.
Reboot your router.If also not working,change you router's sig channel(1~12).

How to fix wifi but no internet problem

I have had a curious problem with my A500 and my D-Link wifi router for the past several days that I just figured out how to solve and I thought I would let the community know in case others are having a similar problem. The symptoms of the problem are this: the tablet connects just fine to the router, and shows a good connection, but most internet apps can't get any sites or pages to come up. They take a long time and then return errors. The Gmail app and Facebook app will still work but Browser, Books, Market, and other similar apps just say "Loading" forever without ever actually loading anything. When I opened up a terminal it would let me ping internet sites, but those same sites would fail to respond to Browser. Everything worked fine on all the other computers connected to the same router, and everything worked fine on the tablet on other wifi networks, but not this one.
I tried several things I read on forums about other tablets, including rebooting the router, dropping and re-adding the network from my tablet's list of networks, rebooting the tablet, disabling and re-enabling wifi on the tablet, enabling and then disabling airplane mode, and setting my router to only accept 802.11g or 802.11n but not 802.11ng connections. None of these fixed the problem.
The solution was this: I used my laptop to log into the router's settings page, and turned off a setting called "WI-FI PROTECTED SETUP". When I noticed that my router had WPS enabled, I first tried to use the feature on the A500 to connect via WPS with a PIN instead of with my WEP2 passphrase, but while connected this way it had the same problem as before. Once I turned WPS off on my router, everything worked perfectly from then on.
So it appears that A500 has a problem with WPS. It may only be with this model of router, a D-link DIR-615, or it may be with WPS-enabled routers generally, or some range in between, but if you have a similar problem where your wifi connection is strong yet pages fail to load in apps, try turning WPS off on the router.
D-LINK (DIR-655) here and I DO have the WPS enabled without the problems of surfing with my A500 ... But I don't connect the A500 through WPS though... just using the WEP key.
However ... I do think it is related to my screen wake issue... others might think differently ( no wake issue when hotspot through my phone carrier at all... only home wifi )

Wifi obtaining ip address....

My Wifi connected to my home router perfectly until I flashed the custom rom.
Now it wont work. the phone recognizes my network, then tries to connect but it pauses at the obtaining ip address bit and doesn't connect?
I tried to restart the router. It doesn't work.
I tried to reflash the rom or offical rom (KE7). It doesn't work.
I also tried to delete the file /data/misc/dhcp/dhcp_list, but there are no "dhcp_list" file inside 'dhcp'
Do anyone have another way to solve this problem?
Thanks
Could be a problem with the router, are other devices able to acquire IP addresses from it correctly?
Perhaps you should assign a static IP to see if that makes a difference.
I am on KE7 stock rom with root and had this problem too. It just started yesterday and got stuck at obtaining ip adress. So I switched WIFI off and flight mode on and after some seconds wifi on and flight mode off and it connected. I also noticed that now sometimes when it is in standby it disconnects from the wifi network (but wifi is still ON) and when I wake it up it connects to my network.
Me too, same problem.
If wifi is ruled on "sleep when screen turn off", it don't wake when screen turn on.
It stay on " searching for IP adress...".
For the moment, I'm forced to leave wifi on "never" and I use Juice defender for disabling wifi on screen off.
I really think it's a common pb with SGS 2. May be it will be fixed with 2.3.4.
Same problem. I 'fix' it by turning off wifi then turning it back on and it gets an IP address immediately.
same problem here with a dlink dir-615 router. from time to time the phone can't get an ip, and it only works if i reboot the router. didn't try with another router yet ( well, i connected to a few more but not frequent so i can see if there are problems), but i ordered a new one anyways since the dlink also crushes my battery too.
try posting the brand/model of the router you have problems with, maybe there's some specific ones that are troublesome.
d-link dir-615 here / ke7 stock - rooted
I also have a dlink router. But I get the same problem with a Belkin.
With my first SGS, no problem. I really think it's a specific issue on SGS2.
I'd read in some place that 2.3.4 will fix some wifi problem known for the moment on 2.3.3...
Let's see...
I'm seeing this with both my home router (Netgear WNDR3700) and my office router. Disabling & re-enabling WiFi on the SGS2 solves it -- fortunately, it's easily accessible on the notifications panel.
Same thing with Dlink dir 815.

Same thing here with Draytek 2820 router, all other devices (PC's Phones, PDA's etc) have no problem. SGS2 however needs WiFi turning off when waking from sleep to get it to obtain an IP address again. However my HD2 also running Gingerbread 2.3.3 works faultlessly.
KF2 seems, for me and some others, fix the problem...
hi
lucky me, i thought im the only 1 having problem with wifi
my problem, same as the others
the wifi try to connect (obtaining IP) and then disconnected
it will scan again, same thing will happened
try with all type of protocols, wifi b,g,n wep, wpa, no passwd
results still same
try to connect wifi at my office, results also the same
im on KF1 using dlink 615
hopefully someone can help us
tq
Just got my Galaxy S2 today. Cannot connect to wifi network on G or mixed mode, with or without security - just tries to obtain an IP address. Ridiculous.
Any help ? Quick search on Google doesn't bring up too much. There does seem to be an app called "FXR Wifi" but I don't expect to use that on a brand new phone.
Update: Upgraded my router's firmware (WRT54GS) and it works !
I have the same problem with my SGS 2. I can't connect to an AP - NETGEAR DG834G.
I found a partial solution to use my phone with my AP until I solve the problem. In the Wi-Fi settings menu enter Advanced mod and set the IP address, Gateway, Netmask, DNS1 manualy (by touching <Use static IP>). If you don't know what IPs you have to set for IP address, Gateway, etc. just connect with you laptop or desktop and use the settings from your computer. Just make sure you type a different IP address in your mobile (not the one from your computer - for example in you computer you'll find something like this: 192.168.0.3, you'll have to type in your mobile something like this: 192.168.0.10). The rest of the settings have to be identical.
Good luck!
To solve this "obtaining ip address problem". Set the following manually in the advanced configuration and save it.
1. ip address(your choice).
2. subnet mask(255.255.255.0).
3. default gateway(192.168.1.1).
4. dns servers(8.8.8.8,8.8.4.4)
Note: The above given values are the most commonly used, you change it if you want so.
After entering these values manually(and correctly), it will connect to the networ in 1 or 2 seconds.
like mine SG s2, wifi connects works perfectly at home and friends place,
but stucks at obtaining ipaddress for wifi, at the mall and college, ( where it needs first login page for authentication) ( or to agree user terms and regulation),
any idea, how to fix this issue.
Thanks
mine also does this where it doesn't get an ip. Reboot your router or just disable and re-enable the access point feature on the router and it should work without having to reboot it

but at university?college or mall, we dont have access to router.
any other idea to fix this

Hey guys! Did you find a fix for this problem? I have the same thing happening right now. I tried at different places, home and country house with Zyxel P660HN and Cisco E4200 respectively. Stuck at obtaining IP address...

Really Frustrating Wi-Fi Issue

Just picked up my TF today, updated to 3.1
I have a main router at my house and two bridged repeaters (dd-wrt) sending the signal everywhere so I have coverage. Here is the strange issue:
I can connect via wifi just fine to my main router, but I can't to either repeater. The TF says I am connected, but the wifi symbols stays gray, and doesn't connect to the internet. Other devices connect fine to the routers, even my droid 2 global has no issues.
Anyone else experiencing anything like this? Strangest wifi bug I've ever experienced, i'm stumped.
I've tried the following:
Channel Changes
Open security
Router Reboots
Any advice would be appreciated!!!
just tried connecting to my dd-wrt for the first time reading your post, and it worked fine... I am running prime 1.4 if that happens to have anything to do with it.
Have you tried static IP on your TF?

A repeater? Or direct router?
I have tried static ip, no avail.
I also have an annoying wifi issue as well. When my transformer comes out of sleep it seems to be connected to the wifi but I can't surf the net. I need to turn-off wifi and turn it back on to make it properly work.
Using Prime ROM v1.4 and the wifi uses WPA.
I should have also mentioned, that despite being "connected" I still cannot visit the router gui via the TF's browser...

+1... I am annoyed with this as well...
mine is a bridge, with it's own ssid
still can't figure it out
I'm considering flashing to prime 1.4 to see if that will help. does anyone know if there are different wifi drivers on prime 1.4 vs stock 3.1?
thx
Have you tried flashing the latest firmware to you repeaters?

Same issue was happening to me on stock rom. I changed WiFi disconnect policy from "Never when plugged in" to "Never". The issue is now gone but battery goes a little quicker now...
Do you know if you have an access list setup on your router? Your access list maybe bllocking your tf from connecting
The first thing I would do in your case, OP, is to disable all security, mac filtering, passwords, etc and see if the Asus will connect or not.
I'm using Prime 1.4 and have no problems connecting to my wifi network using WPA2.
I have...
(1) - Verizon Fios - Main router - no wireless broadcast - DHCP on
(2) - Linksys E2000 - DD-WRT - wired ethernet to main router - broadcasting SSID - DHCP off
(3) - Linksys E2000 - DD-WRT - wired ethernet to main router - broadcasting SSID - DHCP off
Unfortunately, I'm not doing the wireless bridge repeater mode but I haven't noticed anything particularly different about the Asus's wifi.
My wifi is always on, I don't use any of the battery saving modes.
figured it out
After trying a bunch of various resets and google searches, it turns out that the only way for me to connect to a bridged router is by using static ip's and making sure the dns was set to find my main AP.
Its strange that i would have to go through so much manual setup, when all other devices work just fine.

N4 wifi problem, help please

My N4 is no longer able to detect my home network. It detects my neighbor's network and several other networks, although it cannot connect to any other network. When I try to connect to a detected network, it just says "Saved". My home network is working fine and several other devices in the home are connected to it. In fact, my wife's N4 is still connecting with no issues. I have tried rebooting the phone, rebooting the router, telling the phone to forget the network, changing the channel on the router, no success. Running version 4.4.4.
Any thoughts on what might be wrong or ideas for a fix?
Thanks,
b
You haven't inadvertently switched the WiFi frequency from automatic to 5GHz have you? It's just that I had a similar problem and that's what had happened.
