wifi problems?

i'm trying to connect to my home network. It see's it and connects to it... but then straight after it connects to it it totally disconnects and the wifi is turned off... what could be the probelm?

Did the problem persist after soft-reset? If yes, did u install any profiles manager (like phoneAlarm etc. which u can switch wifi on specific time) or did u changed any wifi settings using advanced config/hdtweak/similar apps?

I have an issue with wifi where when i use my works wifi it connects and then should i check IP it clearly shows the works network, however...
when at home and connect to my home wifi it still says connected however when i check my network IP the browser is clearly using the t-mobile 3G internet.
It's baffling to say the least. I've tried closing browser, changing order i open connections etc but to no avail.
Any thoughts?

[Q] unable to connect to any wifi network from the wireless list

my phone can see any wireless network just fine and even can see any network encryption changes but for unkown reason the connect button feels like the cancel button
when i try to connect to any encrypted network it ask me for the password then nothing happens
i tried installing different firmwares and they all do the same thing
now what?!
oh...i tried wifi fix.zip and it missed up the network enable/disable key so i restored my phone back to my 2 days old backup which also suffer from the same problem
i am on CM9 BETA4
when this problem happend i was using the internet on my phone and all the sudden the net access was down so i checked the router log very fast and the last thing i seen on the mikrotik wifi server log was my phone connecting with too many diff mac address (6 of them) with the same ip
i checked the wifi server if my phone's ip or mac was banned and the answer was no
i have one place left and it is the phone itself can a virus unbind the wifi connect key?

turned out that the phone for some unknow reasons doesn't connect to any wifi network with space in ssid name
changed the ssid from space to under score and everything is working again on CM9 B4

[TIP] Wifi connected but no internet connection!

At some points in your life, one of your Android devices connect to a wifi router, but can't connect to the internet. However, your computer, laptop or iPad will connect to that same wifi and use the internet just fine. I've looked everywhere on the internet for solutions, some of them are:
+ Turn off and on both modem and wifi router
+ Factory reset wifi router
+ Battery pull your phone, wait 30s and put it back
+ Reflash stock or custom ROM
+ Change DHCP IP setting to Static
+ Disable security (WEP, WPA) on wifi router
+ Check DNS server, gateway IP address for correctness
Fortunately, I stumbled upon this old thread last night -> http://forum.xda-developers.com/showthread.php?t=1371794
It helped fix the internet connection temporarily, turning off and on wifi on phone caused the issue to repeat.
In summary, he found out the correct MAC address for gateway was mismatched with the one on his phone. Even though the gateway IP address is correct (example: default gateway IP 192.168.1.1)
Upon further investigations, I found out my Wifi ROUTER has the same IP address with my MODEM (192.168.1.1) This IP conflict causes the phone to recognized the WIFI ROUTER's MAC address as the gateway's MAC address. This problem mostly occurs on Android phone, not computer (I'm no tech savvy so I have no idea why)
Simple fix: Go to wifi router setting page, change the IP address on wifi router to different number (other than default 192.168.1.1), and the problem should be fixed.
Please help spread the words to fellow Android lovers, I'm sure a lot of us have struggled with this problem :laugh:

I'm one guy who is desperately looking for a solution to this.
Unfortunately the solution you gave didn't work.

Hi
i have a problem with wifi. it remains connected but loses internet access randomly. i found this solution:
"In the wifi networks, select the network you want and select ‘Forget network’
Turn off the wifi
kill all the apps with your task manager
Turn on the wifi again
Connect to the network
Check the internet connectivity
If still the problem exist, switch off the phone and redo the above steps"
it solves the problem, but it happens again after some minutes. actually, i also installed an app named "wifi fixer" which does the above process automatically. when the program is active, it turns the wifi off and on every 2-3 minutes. and the phone has internet access when the program tuns the wifi on.
any idea?

Turn off wifi optimization on some android phones help.

Had the same problem for several months. Changed my router and everything became prefect.

2 years after the last reply I am having the same problem. My wife and kids all have internet access on their phones, tablets, desktop and laptops all from the same modem router yet I am unable to use the internet on my Galaxy S2 mobile phone even though my phone says connected to Wi-Fi Network Netgear 06.
The Mac address solution provided isn't applicable to my situation as my Mac address on my mobile is different to my modem router Mac address.
Any other solution?

Problems connecting to wifi network with login page (3G still active)

I don't know if this problem occurs only with the OP3. It seems the phone stiil uses 3G if Wifi is not getting a connection (wifi with exclamation mark)
When I connect to a wifi network that needs login, if I don't login the OP3 continues to use 3G instead of failing to connect. This causes me problems to access the gateway page to login, because it gets confused and it tries to access the private IP with the login page using the 3G connection..
I remember my S4 had a possibility of seamlessly switching between 3G and Wifi. Can't I disable this feature in the OP3?
Right now I have to disable the mobile data to force the login through the wifi connection. Is it just me with this problem?
This can be handy in some situations where you loose wifi connection in a public hotspot, due to a timeout, and the phone uses 3G instead of leaving you without any connection. But right now is causing me problems to connect and I must be carefull with huge traffic apps because you can be using 3G instead (look for the !)

I still haven't solve this annoyance. Currently the best workaround is to temporarly disconnect Mobile Data. That will leave the OP3 without internet access, and then it pops the login page (I guess it then assumes the gateway IP is private).
After logging in I can turn mobile data On again.
This is very annoying. Don't you have this problem, especially with corporate wifi networks that require login?

Question Wifi without internet access, but internet (from eSim) not working

Hi
I have been observing this for a long time this issue. When I connect to WiFi without internet access (like dashboard cam etc), my pixel doesn't show me a notification, that Wifi has no internet access. I don't see 4G/5G icon. Just an icon of wifi connection. I also observed, when I connect to a public hotspot (hotel wifi for example), Pixel doesn't redirect me to the website with the "login page" and I need to go to settings of WiFi, copy Default gateway and paste it to browser. The site with terms&conditions is shown and after agreeing I can use the internet access.
I am running on the latest updates, A13, using eSIM as a primary, 2nd SIM just for calling, the device is root. I Tried resetting wifi settings, resetting all "connection settings", try different settings (mobile data always on, adaptive connection, DNS, MAC automatically) but without any change.
Do you have any solutions for this? It is really annoying.
