WiFi connection settings become messed after some successful connections (Workaround)

As some TP2 or other WM device owners I've noticed that WM often seems to forget WPA passwords when using WiFi. It doesn't really matter wether you use AES or TKIP and how long your preshared key is.
In my case the symptoms look like this: After I create a WiFi connection (WPA2, AES, hidden) so that my Rhodium can use my home WiFi network, everything goes just fine. But then, after having established a connection for two or three times the troubles begin. Usually it takes about 3 or 4 seconds to establish a connection. But suddenly it takes about 10 seconds after which I get a warning that the connection could not be established. If I then go to my connection settings, I allways find them completely messed up, so that I have to select WPA2 and AES and reenter my password an so on. Well, after it happends to you for three or four times, this becomes extremely annoying.
Recently, however, I've found a kind of workaround for this problem. And here it comes: After I turn on the WiFi, I simpy wait for about four seconds. If WinMo behaves nicely, 4 seconds are pretty enough to establish a connection. If, however, I don't get connected after these 4 seconds, I IMMEDIATELY turn WiFi off, wait 2 seconds, and turn it on again. With 99% probability this second try gives me a working connection. If it doesn't, I simpy repeat the same procedure once again. So, the scheme is quite simpe:
Turn WiFi on and wait 4-5 seconds (it depends). Got connected?
Yes: O.K
No: Turn WiFi off, wait a second and turn it on again.
The main thing about this trick is not to let WinMo try to establish a connection for more than 5 or 6 seconds, otherwise it will delete your connection settings.
In my case, this workaround works perfectly. For more than two weeks I've been using my home WiFi with Touch Pro 2, establishing at least 4 or 5 connections a day and not a single time my connection settings were lost. Well, surely this thing with turning WiFi on and waiting and turning it off if you don't get connected fast enough is also a little bit annoying, but nevertheless it is much less annoying then having your connection settings all messed up every single day.
I'm not sure, whether this workaround will work with other devices or WinMo versions or even firmware versions, but may be it will help at least some of you affected by this odd problem. So you may just give it a try.
I'm using Touch Pro 2 with stock O2 Germany ROM (1.19.207.0)
Thanks for reading this long post and sorry for my bad English.

Excellent! Thank you for sharing your workaround!
I do something similar, except I turn wifi off by pressing the power button if the wifi hasn't connected in a few seconds. (By default wifi turns off when it goes into standby.)
On the odd occasions where the key does need to be entered again, I keep a copy of the wifi key "somewhere" on the device. It's a copy and paste operation after that, so it doesn't take long to re-enter the key. Luckily you can use the keyboard Ctrl-V method to paste the wifi key into the TouchFLO interface.
The other observation I've made, is that if I switch on the device by sliding out the keyboard, my Touch Pro 2 has a higher chance on getting a 'lock' onto a weak wifi signal. I'm not really sure why!

I'm glad that this workaround works not only for me
Actually, I don't use Connection Manager any more, for I've recently installed Rhodium Keyboard Controller GSM 1.3.2. Using this handy tool I remapped my Home button, so that double clicking it, turns WiFi on and and double clicking it with working WiFi turns wireless off.
I guess that Rhodium Keyboard Controller uses some advanced routine to activate WiFi, because since I use it for establishing WiFi connections, I rarely have to use my workaround, for normally I get connected on the first attempt.

[Q] Is there a problem with your Wifi?

Hold the phone with the keyboard out.. if your pointer finger or any part of your hand covers the top of the device (or rather, left in the case of landscape).. does your wifi signal drop..
Often times it will drop signal completely and then come back up. I also noticed that the wifi is extremely sensitive to line of sight.. If the back of the phone is turned away from the access point.. signal drops.. turn around 180.. signal back up again. Its aggrivating.. this is when holding the phone in portrait mode..
Also..the device does not really roam all that well.. I have my wifi aps setup with all the same SSID.. so as you move through the house using lets say, my trusty HD2 running android, it will switch from ap to ap with no drop.. this also depends on roaming tendency (with computers) - but all in all.. it works perfectly. The G2 just drops the connection, and then connects to the next AP..
So.. do you have issues with your wifi?
btw.. The speeds are pretty good.. especially with PM (iwconfig eth0 power off) turned off. Its the link quality that is erratic..
I thought connectbot would be 10x more enjoyable with a keyboard.. didn't know there was a catch

Ive got lots of issues but I'm torn between if it's my phone or my router... My Vibrant does the same kinda crap but not as often as the G2 does. The PC's will be on, but not the phones.
How can I manually set my IP?? I do the Press menu in the WiFi menu and set static IP and specify what I want, but when I click on the network I'm connected to, it shows the IP that the phone chose by itself

There's a thread open here: http://forum.xda-developers.com/showthread.php?t=926132

Yeah, the wireless sucks unfortunately. I've setup a ton of new routers in my home (I have lots of media equipment and stream things constantly) and it's definitely the equipment. Sucks sooooooo much because the mobile radio sucks just as bad!!!

Pretty much every smartphone has this issue. I've noticed that my G2 drops its cellular signal if I hold it on the bottom-left corner.

Signal is fine, problem with wifi on this hardware is much worse than losing signal. When connected to some APs, screen off = wifi off, even when set to always stay on.

I've come across the same issue. Everytime I hold the phone using my lft hand,my coverage drops from H to edge. As soon as switch to my rt hand I get back on H. Also noticed whenever I hold the phone using just my finger tips to top to bottom I always stay on H.

[Q] Wife issues just recently started on SM-P600

So I just purchased the tablet brand new about 2 weeks ago. Love it for the most part!
Over the past couple of days though, the wifi has really started to act up, and it's passing me off.. About every half hour or so, sometimes longer, sometimes shorter, the wifi will just stop working for a while. The bars will still be there, as will the little "download" and "upload" arrows lighting up as though data is still being sent and received. However, the wifi just isn't working. Pages won't load, speed test . net app won't work, nothing requiring wifi.
I usually have to go into wifi settings to disconnect and reconnect for it to start working again.
I haven't done anything different to my wifi router, and my other wifi connected devices don't seem to be having any trouble staying properly connected, so it doesn't seem like it'd be an interference issue.
Can anyone provide me with some help?

[Q] Shutdown issue (but not the overnight one!)

Hi,
I've been reading the other shutdown issue with interest from the start but I think that my particular issue is different and I'd like to know whether anyone else has my exact problem.
I'm using the o2 UK 16GB version 10A/234 and this is the problem:
When I reboot the phone and it gets to the lockscreen, if the network status is "disabled" on the lockscreen and I swipe to open, the phone shutsdown and can't be started again until I remove the battery.
If I wait for a couple of seconds when the lockscreen comes up, there is a little lag but the phone works as normal.
I can replicate this issue over and over again, so it is not a random occurrence AND this is the second handset that I have had where this exact problem is present.
Does anyone else have this issue?

I'm facing the same issue. Is your device rooted?
At first every (re)boot without being connected via usb to a charger or a computer would result in a shutdown shortly after I enter my pin. After a day of usage I cannot reproduce it anymore, although it still happens from time to time, for example yesterday when I tried to send a text while having very bad to no reception. When it happens I also have to remove the battery or hook it up to a charger, otherwise the buttons/screen would not respond..
I'm thinking there is a (firmware) problem with the chipset since it always happens when my phone is trying/strugling to connect to the mobile network. I installed an app which constantly writes logs to my sd, hopefully that will give me more information about what's causing the problem..
Are you also having bad reception when the device shuts down? My previous device (iPhone 5s) had normal reception in my house, incl. a stable 3G connection, always 2-3 bars of 5. The LG G3 is constantly strugling with the connection to the network and often switches to "emergency calls only"..

This happens rooted non-rooted, stock (no added apps) and always whilst connecting to phone network. Are you on same variant as me and if you leave it for a moment before putting in your pin does it then work ok?. I'm trying to get o2 to change my handset for another model (m8) but they just want to fix my one.

Yes I'm on the same variant. Still running the 10A firmware.
Sometimes it works, but I will do some more test this evening after work and see if I can reproduce it every time and hopefully get some usable logging too.

I think this is fixed in the 10f firmware update that I installed yesterday. I haven't had a shutdown since :victory:

i was facing almost same issue except my phone crashed and don't want to boot up, haven't edited anything just started bluetooth. sometimes it start sometimes it doesn't
now it doesn't want to boot at all even charge screen gets stuck

Quick Charge always on and random pausing and playing

Hi,
So I had the razer phone for a week now and wondering if anyone has experienced or fixed two things:
1) Is quick charging always on?
I can't find any setting for it and I charge at night so I don't need quick charge unless it's an emergency.
2) When using headphones, Google music and YouTube will pause and start playing randomly. I would of thought maybe a unstable internet connection might be the case but even my downloaded music does it as well.
If anyone has solutions or can confirm they have the same issues, would be greatly appreciated.

I have had a similar issue as well. I use slingbox heavily, and when using my Verizon 4g sim for Data only, and Wi-Fi enabled I would see a random Grey (looks like a blank message prompt) blurp appear at the bottom, center of my screen. It would cause my Slingbox app to lose connection and close the video. Once i removed the Sim card from the phone, and use it in Wi-Fi only mode, I do not get the problem. I thought I would share my similar story.
Cheers.

Well, if anyone else is getting the random pausing and playing, I have narrowed down the issue to the USB audio dongle having some wiggle room when plugged in (IE standing or sitting still = no problems but if you're moving, you have a good chance of the dongle wiggling around and causing disconnects and reconnects which is why it pauses and plays).

No I am not. I did not have the phone connected to a charger when i encountered this problem. I came across it when i was doing battery test. I crank the brightness up, and stream my slingbox to see how long they can go. When my slingbox kept dropping connection, but not displaying a network error I started to take more notice of the issue. Once I was able to catch the problem in the act, I saw this random grey window appear at the bottom center of my screen. Slingbox drops the video, and goes back to the main login screen. The amount of time between disconnecting was also random. Sometimes it would disconnect almost right away, other times it would stay connected upto 15 minutes before dropping.
Once I remove the Sim and use Wi-Fi only, there is no issue.
Cheers.

I am in the same situation. With my CDMA/UMTS/LTE sim card I do get a data connection but I have frequent data drop offs. I'd see LTE, one minute then half signal with 3G then no signal at all. Even with cellular data off and only on wifi i would also experience drop offs of from the wifi also. It would even drop my magic jack calls only on home wifi as soon as the other person answered. Took the sim card out and I have no issues.
I think he was asking if you were trolling because we are off topic in that we do not have GSM carriers.
