All of a sudden beginning yesterday my captivate can no longer connect to the wifi network at work. Other users can connect to the network fine and I'm able to see the network from my phone and connect to other networks just fine but when I try to connect to the work network it just shows connecting with the round circle containing 2 curved arrows and then disconnected, scanning, and connecting again.
I have stock 2.3.5 and have tried wifi fixing apps and power cycling without success... Basically I'm stuck at the point of a hard reset unless anyone has any other suggestions for why I'm unable to access one specific wifi channel all of a sudden...
Thanks!
I meet wifi problem like yours, cause of the poor network switcher. After switcher reboot, phone can connect it.
Try Airplane mode on the phone, or switching WiFi on and off. Rebooting router helps too - but probably not an option at work.
It's the router/access point. Reboot that and all is good.

I have a Tilt with the stock AT&T ROM and HardSPL. I keep the HSDPA data on all the time and connect to my wireless access point while at home.
I understand and am fine with wifi disconnecting in sleep mode - email still checks using HSDPA. What normally happens is when I power the Tilt back from sleep the WiFi connects back to my access point.
I've noticed more than a few times however that coming out of sleep WiFi doesn't even attempt to reconnect to the access point. It is on in Comm Manager and appears to be associated with my AP, but checking the IP online shows an AT&T IP addr, not my CATV provider.
The only way to get back on WiFi is to shut off the phone (or reset). I don't want to keep WiFi on while in standby, I just want it to reconnect when it should.
Has anyone seen this behaviour?
Cheers,
Todd
Wifi access point problem
I had a problem where suddenly after months of use with my home wifi router, it suddenly would not connect with the router anymore. Would show that it was trying to connect, and then would suddenly not connect and try another router on the list.
I tried reseting and everything. Tried re-entering the password for my router as I thought that was the problem. finally the only fix i found to work was to actually delete the access point from the phone... then reset and then let it find it all over again from scratch. And miraculously that time it worked.
I know this is not exactly your problem, but hope it helps.
I will try that and see what happens. It seems whatever sub-routine that turns the wifi on isn't running at times and doesn't even attempt to search.
please help me my g1 cant detect any wifi access point on my area.. there are 3 hotspots here with good signals strenght.. i don't know what happened to my g1 it just keep on scanning but it doesnt detect any wifi access point..
I used to own a G1 and I thought that the wi-fi connectivity was very poor on that device. All I can say is to either retry by turning on/off the wi-fi and see if it will connect. Hope that helps.
did you try re-flashing the rom?
Had exactly the same problem, some roms picked up my wifi connection and others didn't, from the wifi menu in settings select advanced. Change the amount of channels from 11 to 14. Phone picked it up no bother then,
When I reboot my Captivate, my Rosewill RNX-EasyN4 router reboots also. When the Captivate tries to connect to Wifi that is when the router reboots. This only happens after I reboot the phone. When I just turn off Wifi and then turn it back on, the router is fine. Even if I turn off the Wifi for a while and turn it back later, the router has no problems. Has anyone experienced this problem before? I am running Serendipity 6.3. I think it was happening when I was running stock also, but I am not 100% sure.
Sounds like your router is flakey. Rebooting the Captivate should not cause a reboot of your router. Check the Rosewill website and see if they have updated firmware for your router. That may solve the problem.
I have the latest firmware on the router dated 2010.07.15. I do not think it is a problem with the router because I have multiple notebooks, a PS3, and a wireless printer connected to it. Only the Captivate causes it to reboot.
Turn off wifi before you reboot.

Tried that already. Once I turn Wi-Fi back on, the router reboots.
Ok, try power cycling the router. 2) try the fxr wifi fix from the market.

Tried power cycling already. Installed and ran the FXR Wifi Fix, but that did not help. I went back to try your original suggestion, turn Wi-fi before reboot. Normally I have Flight mode turned on and Wi-fi enabled. When I reboot Wi-fi is disabled. So I assumed that rebooting with Flight mode on was the same as turning Wi-fi off. But I just tried it and they are not the same. When I manually turn off Wi-fi and reboot, it does not cause the router to reboot. The problem seems to be that when I reboot with Wi-fi on the phone is still in the router's WLAN Client Table. And when the phone tries to reconnect while the router thinks the phone is still connected, it causes it to reboot. At least now I can work around it. Thanks for your help.

Are you by any chance using a wireless N router? I've found that my Bionic will reboot my router every time I try to connect, not just on reboots. But if I turn off the wireless N and just use B+G on my router the phone works fine.
My home wifi network is hidden. I've never had any issues with reconnection after leaving the house and coming back with any other phone, tablet, or laptop. With the s5, I can type in the network and connect without a problem, but if I leave and come back, I'll have to do it all over again. It doesn't seem to remember the network for some reason. Any ideas?
hi all. i am on android 6.0.1 build 23.5.A.1.291. My problem is that my wifi keeps resetting and searching. i am traveling so its not my personal router that is an issue. my tablet and laptop connect to the same routers here without issue but my phone tries to connect various open connections but immediately resets all connections and starts searching for them again. occasionally it connects for a second. the same issue occurs if is set my tablet as a hotspot so i doubt it is related to the available connections. also for some reason i don't seem to have any advanced options anymore to tell the phone to sop scanning. Any help would be much appreciated. so far I tried turning airplane mode on and off as it seems have started at the airport, reset all network connections , general powering down and up etc. nothing seems to work.
hey, i know this post is quite old yet i only found it now facing exactly the same issue. it all started at my parents when phone was suddenly not able to connect (exclamation mark on wifi icon in status bar). i restarted router but it did not help. when i came home i faced the same issue. both routers are different, different provider, etc. before the weekend all worked fine so not really sure what happened. not the phone (z3c) keeps searching for wifi, displays the list for a few secs and searches again.
i tried what was suggested in other topics, like here:
https://forum.xda-developers.com/z3-compact/help/wifi-issues-z3c-marshmallow-fix-t3390859
or
https://forum.xda-developers.com/z3-compact/help/wifi-randomly-disconnecting-575-t3435244
but nothing helped. now considering to re-flash the latest firmware. trying my luck here before i do so.
current sw on 23.5.A.1.291
update:
1) i tried to repair the phone using Sony Companion .. did not help
2) flashed it with the latest sw .. did not help
in both cases sw version was D5803_23.5.A.1.291_1288-5411_R12D. when phone starts for the first time it shows wifi networks. but just for a while, that it starts "searching for wifi networks..". when i select my wifi network, fill in the password and click connect it says "failed to connect to network". i can already see on the background that the phone is again searching for wifi networks. if i try to connect at the right moment network is saved. but then it does not connect. or sometimes it does but "checking connection" takes ages and wifi symbol in top bar keeps appearing and disappearing. at the end it shows error message "could not connect to internet".
what could be the problem?
