Kaiser - Wifi problem (expert opinion needed)

Recently I've been having problems with my Kaiser connecting to my Wifi.
Here is what happens reliably (when phone on it happens more often):
1) Turn on wifi from comms manager (it searches relentlessly)
2) If I try to turn wifi off in command manager at this stage it hangs the comms manager - not even task manager will be able to close it down.
If I turn the phone off (button) then it won't turn on again till a soft reset.
3) soft boot or remove battery - Kaiser comes back with wifi connected immediately most of the time however, it can also come back still searching in which case repeat soft reset or hard reset.
4) Once connection is established - I can connect / reconnect ok till the device is turned off then it happens again. If phone is off it appears to happen more reliably but I've not tested this enough, it happens either way eventually.
So phone on is 95% reliable but can be ok for a couple of times.
5) Once the wifi is in search mode the comms manager is useless and this continues ad infinitum (any attempt to turn wifi off will hang CM) and always a soft boot will bring the device back with a connection established to my wifi point.
Here's what I've tried:
1) Soft boot / battery removal
2) Hard reset without restoring any kind of back up -ie virgin restart
3) Hard reset without allowing custom install of t-mobile software.
Details of my device:
1) T-mobile Win mobile 6 - original rom
2) Hard SPL : SPL-1.0 Oliprof (CPLD-8)
so the only thing I've done to this machine is installed Oli's Hard SPL.
It appears therefore that no software is causing the problem. I am wondering if there's a possibilty of the Hard SPL causing a problem through corruption or do I have a hardware fault with the radio?
I'd be grateful for any help on this as to what I should do next. Please don't tell me to load win6.1 as this worked fine till now so isn't the problem. The only thing I can think of is to re-do the hard spl.
EDIT: Well I've just reloaded Hard spl 1.0 and the problem is the same so I'm out of ideas.

Just a few thoughts - although I do not have problems with my Kaiser, I have met problems with other folks.
1
Is the signal quality good - we know the range is not fantastic, so it's worth checking:
Start>Settings>Connections>Wireless Lan (Icon)>Main and look at the Signal Quality.
2
Start>Settings>Connections>Wireless Lan (Icon)>Power Mode(Tab) and change to best performance.
3
Does it do this with other networks? Don't rule out the Router creating difficulties.
4
Do you let the Kaiser go to sleep mode with wifi connected. If so I'd advise you terminate the connection in comm manager and turn off using on/off button rather than allowing auto sleep mode.
5
It might be better to allocate a fixed IP address rather than allowing the router to set it. Hangs can be created in the IP allocation stage.
6
Do you have any applications set to auto collect data? These could be weather apps, mail, time sync, quick GPS etc etc etc. If so you can try disabling those settings to ensure the crash is not a conflict between setting up the connection and simultaneous data collection.
These can be pesky problems to track down. I suspect that many of the above would be ruled out by your clean boot after a hard reset. If it always works initially after a hard reboot though, it does suggest that another app/process is interferring at a later stage.

Thanks Mike for your valued input.
Just to answer the questions:
1) Yes signal is excellent (I connect in 3 cycles of the animation plus after reboot it connects immediately)
2) I've tried these options - my current setup worked perfectly before, plus of course a hard reset and clean machine displays the same problems
3) I haven't tried on other networks but I've eliminated the router as the problem. I've tried dynamic / fixed - I normally allocate ip via the router plus lock down mac addresses. opened the system. However, this doesn't surprise me because I can cause this lock up without a connection. It's more rare but for instance, if I turn the phone on and delete my signin, normally this pops a dialogue asking which network to connect to. Sometimes that doesn't come up and it still hangs. It is more rare though.
4) No
5) yes tried all optons
6) No and especially not on a clean machine.
I've had the device for some time without any problems so something has changed quite radically which makes me think h/ware. If I were diagnosing this on a pc I'd be looking at both H/ware or a possible driver problem as it the network adapter is locking when it's accessed, however, on this device I don't see the logic of drivers unless they can somehow corrupt in rom even after a hard reset. Is that possible or heard of?
One observation is that when I get the hang and I try to look at the wifi settings I get the following message:
Code:
"To configure your wireless network, please enable your wireless network card".
This little clue seems to point at somethhing that's caused the adaptor to cease responding but somehow in the process locking the comms manager up (ie. if I goto comms manager and try to turn the wifi off, I'll get the spinner ad infinitum). Yet a reboot will kick it back into life again. And notably once it's running, and providing I don't switch the machine off, it'll work till the cows come home perfectly reliably.
I guess my question is whether there is any possible software cause that could exist AFTER a hard reset? Also the reliablity of this problem is enhanced considerably if 1) I have the phone turned on and 2) if I turn the machine off and back on and try to reconnect. Maybe that could indicate a power issue making the adaptor die I don't know what else would make the adapter lock up.
So far I've re-installed the (same) radio and Hardspl and neither of these have changed anything. I could of course go the final step and install the rom again but I haven't done yet as I wasn't sure what components other than the radio might be relevant in the rom.
Edit:
If it always works initially after a hard reboot though, it does suggest that another app/process is interferring at a later stage.

Just to clarify this: Wifi connects 90% after a soft boot initially. A hard reset makes no difference to the behaviour.

It may be a hardware issue, but it would be last on my list of suspects. (I KNOW it must feel as if you have tried everything already – and I think perhaps you have!!!)
Just a couple of further suggestions – since I am certainly not sure where the problem lies.
Having done a Hard Reset, I would 95% rule out a software issue on the phone (though it is possible with corruption of original data – but a remote possibility I think).
I hesitate to suggest a router factory reset, but it may be worth trying.
Two more things to try:

I am curious about why having the phone enabled causes more crashes. Have there been any phone network changes in your area. It crosses my mind that there have been a few reports of wifi problems when 3G is being used. Perhaps you could, as a test, try limiting the phone to GSM only and then testing wifi:
start>settings>phone>band – set gsm on both drop down lists.

Hi Mike thanks for sticking with me on this.

There are a few reasons why I didn't spend more time on the router once I'd established a few things:
1) The adpator actually hangs and it causes abnormal behaviour on the machine. ie. comms manager hangs if you attempt to try to turn off wifi and the spinner comes up. Even more abnormally this causes one of two scenarios, either a) the machine no longer turns off or if you manage to turn off it won't turn on again. So it's causing a major problem with the whole system.
In my experience a no-connect situation never results in a hang, it just times out and a list pops up of other alternative wifi networks it's found and you can always just turn wifi off or use the machine normally at this point.
2) Wifi connects to my router no problem, always has and still will first time from a boot (providing I tried to turn wifi on and it failed before the boot). After a hang and reboot it comes back always connected - doesn't even search, it's a solid non animated connection icon. In other words the card has woken up and therefore has no problems with my router once it's alive.
As an outside chance that the router is getting confused about a disconnect / reconnect I've also rebooted it in between just to make sure - but the router can't tell my machine to hang or fail to respond.
3) I have managed to get this to hang after deleting my settings, ie. stopping it from logging on to my router but rather letting it come up with a list of wifi points it's found. Most of the time the list comes up but after several tests I've confirmed that it does eventually happen. The symptoms are the same when it does. At this point no list appears and we end up with the same deal as in 1)
Having said that I can give the router a try - resetting it isn't too much of a problem as I can backup my configuration but I'm pretty certain it's not the problem bit when problems get wierd then logic sometimes goes out the window and one has to try everything.

I'll follow the registry one just in case but both those threads seem to be from people who can't get a wifi connect at all, usually for s/ware reasons. This is different to my problem which is an abnormal adaptor / system hang caused by accessing wifi.

I'm curious too. I thought a problem with the radio as a whole but I've tested GPS and bluetooth without any problems, both on plus the phone. I also thought that some kind of power issue. If the voltage to the adapter for some reason dropped below a certain point it would kill it till it was kicked back into life. Just a theory. What would cause this, I've no idea, faulty component, dry joint perhaps.
I also had similar thoughts as you on possible changes to the phone service till I finally found it could hang without the phone too just less. This is like 30% to 95%, but multiple on/ off of the wireless and a couple of machine power offs will get it to happen when the phone is off. It just takes a bit more encouragement.
As for 3G I have mine disabled. I only ever turn it on if I am out and need internet via my service. I got caught out when T-mobile's 3G kicked in, in my area and my battery life went to hell about 18months ago - since then it stays disabled.
EDIT: This may or may not be relevant but I hadn't figured out which situation causes failure turn off. If comms manager is hung after a trying to turn wifi off the machine WILL turn off but not back on again. I just found that one other dialogue that hangs is going into the Wifi settings > network adapters > IEE 802.11b/g wifi adapter. This dialog hangs solid. At this point the off button does nothing. It's a reset. Just a strange reversal but it's also a confirmation that the adapter itself is the problem or has been put into a very nasty state.

[Q] Can't turn on WiFi on my Diamond

Hey all,
I was bring back a Diamond from death, it was stuck at Smart Mobility Screen.
Now its alive, i have tried over 5 different ROM's 6.1, and 6.5 too, but whenever i try to turn on WiFi either BlueTooth, its just start thinking, then remain off.
Nothing happens.
Is this a ROM Bug or what?
Where can i find an original HTC ROM for it, which should be working fine?
Thanks in advance.

with WiFi OnDemand HTC by Krocher will allow the phone to activate and connect to the WLAN first and use it instead of connecting directly to the GPRS/3G. In cases when there is no Wi defined / known - Fi is found, the phone will connect to GPRS/3G. There ` s no need to disable your Wi - Fi, then it will turn off after a while the device is suspended.

Same problem over here.
A couple of days ago, I tried connecting to my home network, the way I always do, only to see the Wi-Fi icon on the top bar show up for only a few seconds, and then disappear (I was connected to the same network an hour earlier, and everything worked flawlessly). A few attempts later, it even stopped showing the icon. In addition to that, I lost the (Windows default) network list tab (Settings > Connections > Wi-Fi > Wireless Networks opens the network adapter list ('Configure Network Adapters')). After that, I tried soft resetting, hard resetting, then changing ROMs (MTTY step included), to no avail. Last night, miraculously, it started working. Now it's dead, again.
Any help would be greatly appreciated.
EDIT #1: This video sums it up: http://www.youtube.com/watch?v=G_jQc1JRGQI
EDIT #2: A couple of possible culprits:
1) Loose antenna/cable as in http://forum.xda-developers.com/showthread.php?t=846650
2) Erased EEPROM; possible solution: http://forum.xda-developers.com/showthread.php?t=597195 (in my case, I doubt it's this one, as everything was fine both last night and this morning)

I can not turn it on at all.
Can't get it turned on ever.
When i click "ON" the icon starts spinning the wifi remain off.
I did updated the ROM,and Radio too, tried over 10 versions, and no success.
I will also get an error message sometimes "We're Sorry, device.exe stopped working" or so..
So my problem is not that.

same problem
any ideas ?

WiFi Issues with Android version > 2.3.3

Hey everyone,
I'm having some issues with any ROM using android 2.3.4 or 2.3.5
so far I've tested it with CyanogenMod7 and MIUI 1.8.18 & 1.8.19
The issue is that, regardless of my settings, my phone is being a stubborn ***** and decides to kill my wifi-connection whenever I lock my screen. I don't get any notifications for email or whatsapp whatsoever until I wake my phone. Getting called and textmessages do still function normally.
(If it is of any help, the radio version I use is in my signature.)
Wifi sleeping policy is set to never,
Regulatory domain (wtf is that?) set to 13 channels. (Default.)
Backround sync & Auto sync are turned on.
--
I have fixed the problem with my wifi dying when my screen locks,
I have tested this by playing songs over the network with my phone sleeping (Didn't use to work, now it does.)
However, I have encountered a new issue. My WhatsApp Messenger doesn't seem to connect at all!
Won't send any messages, won't update groups etc.
I have tried re-installing it several times.
Any ideas?

did you try full wipe, or connect to other wifi access point?

I'm trying a full wipe and reflash now, thanks for the tip.
Unfortunately, I don't have access to another wifi access point so I can't try that.
--
Done reflashing after a full wipe -- It seems to have fixed my problem!
Thanks for the help.

New issue, I'll explain in top post.

Strange problem with wifi and mobile data (internet connectivity in general)

Hi
I have a Galaxy note 5 and there's a strange problem with it after upgrading to android 6.
The problem is with network connectivity of applications which go to background. For example with "whatsapp" application, when I am voice calling someone else, as long as the call activity is in the foreground (I see the call screen on the phone) everything is fine. But as soon as I press the home button, The app will loose connection and the call just fails (says "Reconnectiong" but will never connect). The other example is with "Skype" with the exact same problem. Other example is the system's download manager. When any application (better to say activity) requests for a file to be downloaded using the built in download manager, as long as the app (activity) stays in foreground, the download will continue but as soon as I leave the application, the download will disappear as if the connection has been lost. The strangest part that I found out about is that When I connect my phone to charger or a pc, these problems will resolve.
Any ideas about the problem and its solution?
(ps: I tried resetting the phone to factory settings, flashing it, and rebooting the phone like a thousand times.but none of them worked)
thanks in advance

anybody?

[resolved] P9 Wifi and Bluetooth will not turn on

If I try to enable bluetooth or Wifi it refuses to switch on
it just tries for a few seconds before giving up
Edit:
[Resolved]
I ended up sending in my device to Hauwei to get repaired, since the device was less then 3 months old they ended up replacing the whole phone with a new one

This may be a dumb question but have you tried restarting / turning the phone on and off yet?
Also sometimes installing a System Update via OTA can fix this problem. (You can redownload the current system software version that is on your phone and just update it on top of the existing system software without losing data).

I have exactly the same problem - "If I try to enable bluetooth or Wifi it refuses to switch on ". Only wifi and bluetooth. Any ideas what should help?

What fw version do you have this effect?
I am on B378 which I got OTA.
When I go to settings, bluetooth and i disable bluetooth there, the switch turns gray and I cannot enable it anymore. luckyly, enabeling BT still works when I do it from the drop down menu.
I have a worse bug with settings, more, mobile network
it worked after the update, but after sometimes enable/disable data roaming, the screen closed by itself and now it is not possible to enter this submenu anymore. when i tap on "mobile network" it briefly shows "no service" in the top left corner but the menu does not open. if I tap mobile network again, the whole settings menu will close.
any idea?

Yes, also B378 and OTA.
And in "About phone" > "Status" > "Bluetooth address" is Unavailable.

I tried installing cm13, after even that failed to fix the problem, I noticed that the mac address I got when using cm13 was the one you normally get before wifi is initialized (I believe it's 00.20.00.00.00 or something)
From my experience from reading the posts on the cm13 port for my old htc one mini 2, these told me that the operating system wasn't seeing the wifi hardware in the phone...
So after relocking the bootloader and flashing the stock rom (still didn't fix anything) it seems that it may be a hardware failure...
