Unable to start wifi

I searched all over the internet and was unable to find an answer or solution.
I Installed RegawMOD's latest rom.
Wifi was working just fine, The last time i remember that it was working was before used the toolbox and before installing 2 or 3 games. I think that something messed with my wifi driver because when i try to turn it on it says "unable to start wifi", then when i try to turn on airplane mode it says "unable to turn off wifi" When i try to run the Wireless Tether it says that the tethering started with errors that i should check the log. The log says the following from the bottom going up:
Tethering now running DONE
Enabling access control DONE
Enabling IP Forwarding DONE
Enabling NAT rules DONE
Activating wifi Interface FAILED
Configuring WIfi Interface FAILED
loading wlan.ko module FAILED
Does anybody have any useful information that may pertain to my situation?
Everything else is working perfectly. this is the only thing that has ceased to work.
Kernal issues, look at other post i made in ur other thread.

[Q] Data connection problem

Does anyone know why certian application, which use data connection (3G) works properly. Examples: Opera Mini, FB Application, Fancy Widget...
while some do not work. Examples: Daily Briefing, Skyfire, Default Internet application. I get: Page can not be displayed or Connetion Error.
It is interesting that if I am using WiFi, all application works without problems.
I had many different ROMs and it is always the same.
i don't think it's an application error
rather an issue with the APN settings
what are the APN settings for your cell phone network operator?
did you configure it in Settings?
Of course I did. I am using setting from my mobile provider.
It looks like some ports are blocked because when I go into Internet app. and go to google.com I can see that there is some data transfering because the icon of 3g is red and green, also there is the green progress bar in Internet app. loading. However, after 10 seconds of doing this I get: Page is unavailable.
Completely the same in SkyFire.
On the other hand, with Opera Mini it works as it should. The page is loaded correctly.
yes, i've heard reports from other people with similar issues with some cell phone providers
try with opera mini, opera mini works differently, you might be able to bypass the blocks with opera mini
Something tells me you installed froyo and now back to eclair.

I was just about to post a new thread but this one had the same title.
Does anyone else have a data connection problem with JPK? It says my data connection is on but it wont let me use it.
This problem is very annoying and i would appreciate if someone could help me solve it.

wifi keeps searching

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?

Wifi tells me that i hasnt connection to the internet. But, in fact, it has.
I can browse the web for about 5 minutes. Then it switches to mobile data. Any idea how to figure out that problem?
