WiFi troubles on ICS - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Wifix is the key -> http://forum.xda-developers.com/showthread.php?p=21406675

Reconnecting Wifi Acces Point

Hi, I have connectify installed (bcz I've not router, only pci wifi card), but my phone reconnects every 30s-2 minutes. When I'm playing online or downloading, it's really annoying. It's doing on every rom, but when I installed CM7 I was able to connect to adhoc and it has never reconnected. Now I've installed CM9, which still hasn't adhoc support, so I'm wondering, how it's possible, thah Acces Point reconnects and adhoc no. Any solution (or adhoc solution for CM9 )?
fuc k yeah!! i have this problem too after i flash .42 from .62 fw using flashtool.
when i try to download gameloft games files which is often 100mb+ my wifi disconnects and reconnects itself which is annoying.
so can anyone fix this? although when i first bought my mini pro which is .42 originally installed doesnt have this problem.
My problem must be somwhere in that wifi card or PC, because other wifi networks don't reconnect. So now It's all about adhoc for CM9 (4.0.3).
Try an experiment. Install Virtual router, is free of charge, see if it continues to disconnect. If it happens just as likely the wi-fi card is to blame.
So it's the same with Virtual Router. But why is adhoc working great and AP not?

Xperia Ray ICS 4.0.4 - Repeater - Switch to Access Point with strongest signal

Hello Together, I'm running the Xperia Ray on SE Stock Rom 4.0.4 with Sirkay's kernel 8.22 and realised a problem with the WIFI connection.
To expand the range of the network I installed a Fritz!Box 7390 (newest firmware) (base station) and connected a further 7270 Box in WDS mode with the same SSID and the same password.
Unfortunately the Ray doesn't switch automatically between both access points. It only switchs by disabling and enabling the WLAN in the menu.
Hansip87 wrote in his tutorial the WIFI Tweaks (Burstmode . . .) unfortunately they aren't available anymore in tiwlan.ini only the option for 2,4 and/or 5Ghz band.
Does anyone know how to force the ray to switch the access point if a stronger network is available? I tried the app WIFI jumper, but it doesn't work. Therefore I tought, the problem is caused by the settings of the ray.
Maybe someone can give me an adivice.

[Q] Wifi problems [RAY]

Hey guys,
I own an Xperia Ray and just recently upgraded to CM10 FXP201
I had no problem with the rom so far but the only things that bothers me allot is the wifi connection.
I tried both fly and LuPus kernels with the appropriate wifi modules, but the wifi doesn't respond after 2 minutes or especially
when I try to download apps bigger then 20MB. Sometimes i have to turn the wifi on and off until it gets connected but then
it just dies again.
What I want to ask is, is the wifi problem the same on all devices or is there a permanent solution to it ?
Thank you for your time,

Workaround for WIFI issues on XPU after ICS upgrade

After upgrading to ICS 6.1.1.B.1.10 on my wife's new XPU had no issues except for the WIFI bug.
It refused to connect. So after a bit of trial and error here is the workaround I found and I am sharing just in case anyone else has the same issue.
1. Login to your WIFI router and change security to WEP with a shared key.
2. Set a key which is exactly 5 characters. a-z 0-9
3. Connect to wifi from your phone.
VIOLA!!! works. Its a major bug and sony should get this resolved soon.
But until then here is my simple workaround.
Switch router to b/g mode only (not n).
Use WPA2-PSK
--> Safer
Might as well not bother with security if you're using WEP.
Never had a single problem with my Xperia U and wifi on any firmware, using WPA2 and a 18 digit pass code.
I have never had wifi issues either, and my girl has an Xperia U too and same as me, perfect wi-fi.
Try to restart router if you can
My GF has the same problem, after the update to ICS (on the Xperia U) every time she tries to connect to WIFI it works for a few seconds and then it stops.
But that's not all, after that, nothing connects to the WIFI anymore, all active connections stop, the router sends data to LAN (wire) only,
I can't connect any device to the WIFI, I tried with my Galaxy S, Xperia S, even the laptop.
I have to restart the Router to have WiFi again.
Does anyone know a solution, except the dumb one to turn my router to b/g?
I have another router (old one WRT54GL) and it's not even working on this one. No connection, despite the fact that it's a b/g router.
Use Flashtool and put the .54 or c firmware on
Sent from my Jellybean Xperia S
i faced same problem after upgrading to vodafone ics but resolved by itself..........LOL

WiFi Trouble(s) ICS & JB: Reconnecting, Dropping, Loosing Connection

I have used this fix successfully on several different ICS (Ice Cream Sandwich 4.0.X) and JB (Jelly Bean 4.X.X) tablets to fix intermittent WiFi problems. It is simple and worth a try if you are having difficulties:
Unfortunately you'll need access to the root directory either via ADB or by rooting the device.
There is a file, wpa_suplicant.conf, that contains the WiFi connection instructions for networks that you have previously connected to. Deleting this file and letting the Operating System rebuild fixes a variety of intermittent WiFi issues (not hardware issues like poor signal.)
Locate the wpa_suplicant.conf file in data/misc/wifi using ES File Explorer or some other method of your choice
Turn off WiFi (Settings - WiFi)
Rename the file wpa_suplicant.conf.bak or just delete it
Restart the tablet
Turn WiFi back on
Restart the tablet again
Jelly Bean 4.1.1 Dropping, Difficulty Connecting
I am going to add to my own post. I found something that fixed the Jelly Bean dropped WiFi issue - the WiFi Connector Library
The JB WiFi problem:
WiFi works fine if you connect to a secured network (WPA, WPA2.) But if you are connecting to an unsecured WiFi network, one with no password protection, it is difficult to connect and once connected the WiFi drops frequently (30 seconds to 1 minute for my N90II RK3066.)​
This is again an easy solution to try. It worked for me:
Download and install the free app WiFi Analyzer
After the connection has dropped or while still in the difficult to connect phase, launch WiFi Analyzer
Use WiFi Analyzer to connect
Go to the AP List View (middle button at bottom)
Click on the network you want to connect to
It will ask to download WiFi Connector Library
Select "Yes Please"
Play Store will launch
Install the library
You should be A-OK once the library is installed
It runs as a background service. I can only guess why this works, but after three days of messing with this issue, I think I'll just smile and go on to something else.
