[Q] Wifi problem for WPA/WPA2 - Nexus S Q&A, Help & Troubleshooting

my nexus s works great with wifi WEP.
for wpa/wpa2, no problem for connect and use, but can't use after sleeping (screen off). wifi sleep policy has been set to "never". after waking up, the wifi signal is there, in grey, not green, and actually cannot use at all.
any idea?

I seem to have the same problem. Did not circle down it yet to WPA but might be... I disable/enable wifi to fix it. Annoying but works.

I have the same problem with my htc sensation. At my home when i set a WEP security my phone connects to it but when i set WPA security,it doesnt connect to it,always refresh and searches but doesnt connect, Fix programs doesnt work please help guys.

No internet via wifi?

Hi guys,
I've recently become the proud owner of a vodafone touch pro. However when connecting to wifi, opera etc will not find any webpages. Now i know my wifi is working and the phone connects fine and picks up the DHCP ip address.
What could I be doing wrong? I've noticed data connections is disabled but I believe this is just for GPRS etc? Either way how can I confirm my wifi connection is being used?
Many thanks
EDIT - NM it was because it was not set to work
Hi Scribe,
I had the same problem as yours. No solution so far. Had no problem with GPRS.
I have mine working good on either wifi or GPRS.
Probably it's wifi problem? Have you tried on another wifi connection?
what was not set to work?
I have the same issue, connects to wifi but no internet. laptop connects and browses fine, but touch pro (and also diamond) don't
Make sure when you set your wifi connection up you say that it is used to connect to work not the internet, also make sure your adapter settings say this.
The problem is that the phone will always default to GPRS/3G for the internet but if it senses a local work network it will use that first.
Stupid I know!
I have the same prob, I changed some settings and it works. Try change Authentication to Shared instead of WAP-PSK, Data Encryption to WEP instead of TKIP. After you have internet connection, you can change to previous wifi settings with same network key.
Mine has gone again! I swear it's because 'Connects to the internet' wont save in the proxy settings - nope not that and still wont work, I've also tried by disabling all security

Problems with Wireless security (WPA-PSK)

I can't seem to connect to my work network that is using WPA-PSK security. Anyone seen this problem before. I've double and triple checked my key and my laptop works fine.
I have no issue. I have WPA-PSK at home. It works fine
tried any other network?
try toggling aes vs tkip and otehr small settings like that. it's got to be a small setting that you're overlooking. i've used encryption on multiple wpa-psk networks and they've worked flawlessly as long as the settings were entered correctly. try again!
Have you got MAC address filtering turned on? No amount of times trying to connect, even with the correct key will give you access if that feature is turned on.
funny... I just got the same problem on the same day...
I used WPA-PSK for a long time untill the day. My TP just couldn't connect to my access point. Another laptop works normally with this.
I've tried without WPA-PSK. It was normal.
Yes, I've tried to re-setting WEP-PSK or check at MAC filter already
Trey setting the time to the time on your router as it sounds to me at the time is different as WPA is a temporal keying system time is a factor and sounds outside the maximum driff
have issues sometimes less after i changed to wpa-AES instead which is also more secure
but one thing I found fixed the issue was to power off the router for 10sec and plug it in again so think some routers get dizzy but too many reconnects by the same device
as I had the same issue with my ipod touch but never with laptops and desktops using wifi
I'm not sure if this is the same problem I had before but..
I used to have a problem connecting to my university's wireless internet. It was protected with WPA too (not sure about PSK part). What I found was if you keep pressing the connect button really quickly, it'll eventually connect after a few tries...
There's a chance that it the wireless router that you're trying to connect to. I remember in the past some firmwares weren't compatible with certain devices (cant remember where I read that).
I have the same problem connecting to a wpa-psk network at a friend's house, but works perfectly fine on my home wpa-psk network. No filtering or any special settings on either network. You should try another network to see if it works.
Also, strangely enough, if I enable wpa authentication in the Advanced Configuration app, it doesnt work. So I have that disabled.
try reboot your router and maybe everything back to normal. I have the same problem and even worth my laptop couldn't connect to the Internet.
I don't know if there is a timeout for encryption setting .
My problem was resolved. Not sure if this will work with your TP. I found this solution somewhere here. Thanks to them.
Go to "Advanced config" program (if you don't have it, u can find it somewhere here)
then under "Network"
set "WPA authentication" to DISABLE
Maybe I have changed it by accidental before.

Wifi not being detected

Hi all,
I'm having an issue connecting to wifi at work. We have several (15+) wifi networks that I can detect via wifianalyzer on my phone. But when I go into the stock wifi settings to connect to them it doesn't list ANY of them and is constantly scanning. Is there anything that I can do to fix this? Has anyone else experienced this?
-Derek
Turn off wifianalyzer, turn off wifi, turn back on, scan for networks again. didnt work ?
turn off wifi, restart phone, turn on wifi.
Should do the trick.

Wifi stops working after being left for a while (still connected)

Having an issue with the Tab 2 where you go to pick it up and start browsing after it has been sitting around a while (not sure if the time matters, but it seems like after sitting for most of the day) and the wifi is still connected, but nothing works than needs data. It acts like it would if you had not internet connection. Toggling the wifi off and on will fix the issue and notificaitons and emails start pouring in.
Anyone else have this problem? I found a similar issue on the 7.7 forums but nobody reported a solution and I am not even sure if it would have worked on the Tab 2 anyways. I am thinking about making a script that toggles the wifi automatically if it detects it can't connect to the internet. But that is a little ridiculous needing to do that. It shouldn't be losing connection in the first place.
Hi Pirate
it's a bit depending on the ROM you have installed - but since Android 4 you have a quite reliable setting. The default behavior of Android devices is to deactivate the wifi connection when it goes to sleep.
Some ROMs don't recognize the disconnection and the switch/button still shows "Wifi on" although disconnected.
First step: go to settings / wifi settings, hit the menu button (top right three dots) and check the advanced settings.
Somewhat like "Keep WLAN active in standby" - set this to always.
That should solve it already under android 4.x
If this doesn't help, look into Play Store - search for "wifi keep alive". But for the SGT 2 you shouldn't need it
Greetz - Chris
It was already set to "Always" so I don't think that will help. I will look at that app to see what it does.

wifi turns off when not in use to save battery. I think it might be a default even if you have it set to always on.

The problem is that it never comes back on. Well it shows the wifi icon and the signal and everything but it just doesn't have any data connection. Any apps that use data act like wifi is off. The only way to get it to start working again is to toggle wifi or reboot. I also forgot to mention it is the stock ROM, only rooted. It got the OTA a few days ago too and it has happened since then.
You're not alone

It's the same effing stuff people suggest to every wifi glitch out there.
To people who think it's due to the wifi sleep policy: although I've set it to always, why would wifi not resume, after screen is turned on? It's not the wifi that gets disconnected, it's the internet (or the download speed) that stops working.
To people who suggest it's a power saving feature under low battery conditions: Sorry, I've tested it while charging and with full battery.
To people with the above two arguments: Connection to some routers works perfect with the phone. Like when I turn on the hotspot on another phone, the wifi works great. Also, wifi on the other phone from the same source (laptop used as internet access point) works well.
To people who suggest resetting the router or wifi on phone: The internet does start working again, but only for a few minutes. Even if the screen is turned on, the internet may stop working mid-download.
The actual situation is that the phone disconnects from the internet, but keeps showing a connection to wifi. Like I used connectify hotspot to create an access point, and after a few minutes, the phone moved from "connected clients" list to the "previously connected clients", even as the phone showed connected to wifi with even the download arrows blinking, but no internet (or download speed). This only happens with certain sources (of wifi). And other phones may work well with the same source.
I have tried (several times and in different orders and permutations) the following to no effect:
1. Resetting the router.
2. Resetting the wifi on laptop.
3. Resetting the wifi on phone.
4. Restarting the phone and laptop.
5. Static IPs, gateways and DNSs. (Even though the problem was not with connecting to wifi and even internet works momentarily after resetting wifi).
6. Turning off items controlling wireless network in wireless connection properties.
7. Turning off firewall.
Waiting for a savior.
I know this isn't super helpful but I had the same bug you describe on the previous version of carbon. When I updated to the latest it seems to have stopped.

After disabling WMM capability in the router the problem disappeared!

Same issue. also using connectify and also tried all things you have described. If you find any solution please let me know.
I had the same problem on my Huawei Honor. You need to set static IP in wifi settings (when connecting to AP, press "show advanced settings").
Mine settings were:
IP adress: 192.168.1.75 (make sure other devices are not connected with this IP)
Gateway: 192.168.1.254 (it could be different. Use the same as you're using to connect to your router)
Network prefix length: 24
DNS 1: 8.8.8.8
DNS 2: 4.4.4.4
No option for static IP in connectify

There is no option in connectify for static IP and in USB wifi dongle also there is no option to set static IP.
Help!

1. I have had the exact same issue for (atleast) the past 2 years. Have survived by repeatedly turning wifi on and off.
2. I too use connectify. This issue doesnt seem to happen on every wifi connection (just like your case). Even more specifically, it seems to happen ONLY when I connect my phone to the hotspot created via my laptop (connectify).
3. Even when the internet is actually working, some apps do not seem to recognise that(take some time to realize it is working), while others are able to connect instantly. Specifially, whatsapp is unable to send/receive messages for about 1-2 mins, after which I receive a whole bunch of messages at once.
This does not seem to be an issue due to connectify as well. I have tried creating a hotspot from my laptop without using connectify as well, but unfortunately, nothing changed. Further, this does not happen when my phone connects to a hotspot created via connectify by some other pc. The wifi and internet work perfectly fine when connected to a hotspot created via my friends computer.
Further, this problem happens only when a mobile connects to the hotspot. Doesn't occur when another laptop/PC connects (not sure about tablets).
I have looked into every nook and cranny on the internet, explored every forum for any working solution, but have been unsuccessful. In fact, this is the first place where I saw the exact same problem as mine, and was wondering if you have found any solution to it .

I'm having the exact same prob on my ZTE Grand x V 970
It started when i had kitkat and i couldnt even "fix it" restarting the wifi, i had to reset the phone in order to have my wifi work for like 2-5 mins and then stops recieving data, tried to reconnect and stays on turning on wifi.. Now i changed to the stock Rom and the problem is still there but at least now i can "fix it" restarting the wifi connection until certain point.
Issue sharing internet with Connectify from PC
Go to:
Control Panel\Network and Internet\Network and Sharing Center
On the left column, click on CHANGE ADAPTER SETTINGS.
You should be in: Control Panel\Network and Internet\Network Connections by now.
Then click on: Microsoft Virtual Miniport Adapter and click on Properties, then click on the 'Configure' button in the 'Networking' tab. From this window, go to the 'Power Management' tab and uncheck 'Allow the computer to turn off this device to save power'.
This works for me. Try this out
If this doesn't work further, you can try out mHotspot for the same purpose.
I've had the same issue, with the wifi saying it's connected even though it isn't.
This thread is 4 years old and this issue still hasn't been fixed. What a shame.
Same issue here on OnePlus 3 even after factory reset.
I have this same problem after the security patch Mid March to Jan 1, 2019. The WIFI doesn't show in the top status bar, but toggling wifi off/on fixes it till the next overnight. I did make one change to my wireless about that same time and that was moving the min connect speed from 6Mbps to 12Mbps to help with bandwidth issues being cause by devices using low speeds and having several SSID broadcast. My S7 and Tab A both work fine - so I think it was something in the security patch.

WIFI issue

Hi, I keep losing internet connection whenever I am on WiFi, although signal is strong and WiFi icon keeps showing full in notch. I already reset my router and network. Anything else I can do? WiFi is always on during sleep, by the way. All other devices and smartphone work fine on my WiFi network, it's only the OnePlus 6.

Some routers have a setting you must disable, or else the op6 can kill the internet for a few seconds.
LAN>Switch Control and set Nat Acceleration to Disable (on router) may not be the right path for you to go on your router but search for nat acceleration helped me on my Asus router.
