Xda IIs & WLAN/GPRS issues

Upgraded from Xda II to Xda IIs end January and initially WLAN worked fine, but no GPRS. Went though process of creating GPRS connection (with O2 Support) and now cannot get IE to connect through WLAN. It always tries GPRS! Has anyone experienced this and/or got a solution?

Mike,
You will need to give us some more info on your settings.
If its an O2 unit with original firmwware if you back stuff up try a hard reset to get default settings back and ensure GPRS works then add the WLAN.
I live in Caldecote just outside Cambridge if you get really stuck we could meet up and you can try and copy my settings and check your SIM has GPRS enabled using mine that kind of thing.
Cheers Wayne

Many thanks Wayne. I'll do a backup and hard reset (with trembling hand no doubt) and see where I get to before getting back to you. Many thanks for the offer of help. I'm in Barrington, so it's not a million miles to come to talk if necessary.

you might already know this mike and if so at least it may be of help to others.
if your gprs connection is active then it doesn't matter wheather the wireless lan is on or off, internet explorer will always connect to gprs.
switch off gprs by clickiing on (in my case O2) your service providers icon and if "mobile web" is highlighted then click on it to switch it off.

Thanks, but I'd tried that and more. Eventually, as Wayne suggested, I did the dreaded hard reset and restored everything from scratch. I now have WLan working on my home LAN, but as I have such lousy GSM/GPRS coverage here I haven't yet tried to see if the GPRS side is now going to work. That's for tomorrow and where I started in the first place when I found it wasn't working! :?
Thank everyone for the suggestions.

Hello Mike
I had the same problem, and after thorough search I found the solution:
start->settings->connections -> advanced
select networks : both drop-down boxes are set to
"my work network"
This prevents the automatic gprs connections.
If you want gprs you can use the wireless manager
(start->programs->wireless manager)
and there tap the red gprs icon
In other words RTFM....

WiFi won't turn on until soft-reset

Hi,
I tried searching for this, but couldn't find anything, so I'm hoping someone here would be able to help out. I currently have a Siemens SX66 ROM v1.40.00 WWE, Radio v1.13.00 ExtROM v1.40.125 WWE
Now, it's strange, but, if I don't have WiFi activated for an extended period of time, and I try to turn it on from the WiFi Manager but what happens is, I'll get that rotating "wait" icon with the colors, and then the WiFi will NOT turn on. However, if I perform a soft-reset (which I don't like having to do, cuz then the "phone" is out of commission until it's back up and running), the WiFi'll be automatically on when it finally loads up fully from the soft-reset.
I don't suppose anyone knows what causes this, and if there's any way to fix this? I'd be forever obliged!!
Thanks,
Quordandis

Hi
wifi always had some bugs :/
I don't know if you have the latest ExtRom though.
PH20B models' newest is 1.40.176
I dont know if there's any newer for SX66
I suggest you check the wiki and upgrade if possible.

I also have this problem. This come from BT.
I have PDA2K unidirectional patch installed. Do you also installed it ?
Let me know as maybe this come from this patch.
May workaround for this is :
Turn on/off BT.
If not enough I also do after turning bluetooth on/off
Settings - Connections
Connections
Configure Proxy server
Check :"This network connect to Internet"
Leave uncheck ":"This network connect to Internet through Proxy server""
This always made me the trick to get back my wifi without soft reset.

Network Profile "Stuck"

Hello everyone! My SX66 is acting funny. I just hard-reset it yesterday to get a clean build due to some other bugs that popped up after hard resetting and interrupting the automatic ExtROM CABs installation. Now everything seems to work fine except that I can't connect to the Internet. The WiFi shows strong signal strength and that it's connected to the AP, but in the network settings it says that it's trying to connect to "Work." Well, I don't want to connect to "Work" cause I don't have a special VPN or anything, just a plain old AP. So I change the setting and click OK, but as soon as I do that, it changes right back. I've tried turning the interface off and on again after making the change, but it always reverts to Work. Does anyone know the Registry key for this value? I have had other instances where a value seemed to be stuck and I successfully changed it in the registry, but this one is stumping me.

Ok, now it appears that it's no longer the "Work/Internet" selector that's broken, it's the Network Chooser in the Settings menu.
Normally, you have My ISP, My Work Connection, and whatever your GPRS/EDGE provider is... In my case, it's MEdia Net. Well, there's a fourth network in there that appears to be sort of symlinking to the My ISP connection profile. I know it's not supposed to be there. I can rename it, but I can't delete it, and whenever I select My ISP as the default, the system selects the other "clone" of that profile. Other than doing another hard reset and hoping for the best, I'm out of ideas.

Uh... He he he... I fixed it... well sorta.
The AP wasn't connected to the internet.
It's not actually mine, it's my school's, but still...

How to disconnect GPRS?

How do I disconnect a GPRS session if I want the phone to use a wifi signal instead? Is there any way of telling the phone to always use wifi in preference to GPRS if possible?
The shiny new phone has just arrived, so lots of questions!
TIA

Hmm well I'm not sure if this works on Rhodium, but on many HTCs keeping the 'hangup' button pressed for a few seconds will disconnect cellular data connection.
If not, go to "Comm Manager", this should also have a button to disconnect it.
If that doesn't work, there's always datadisconnect.exe in \Windows (though that would be a silly thing to do every time )
Anyways, if you have a Wi-Fi connection, all connections made after that point should go through Wi-Fi automatically. Existing connections will keep using cellular data, until they are de/re-connected, unless the program asking for the connection specifically requests to use the cellular connection.

No luck holding down the Hangup button - I tried holding it for 10 seconds and the GPRS session stayed open.
I'm concerned about the situations where I think I'm connected to wifi but there's been a DHCP problem or something, and the phone quietly goes and uses GPRS instead (so the wifi icon is shown at the top, but there's actually no network connectivity via wifi).
Does anyone have a good solution to this?

There is an app available called "NoData" that lets you switch GPRS/3G/HSPA off. But you have to switch it back on to use it again...

I just found an option to configure the Hangup button so that it turns off GPRS, so problem solved! (by default it locks the handset)

You need to do some "RegEdits" to obtain this.. go here...
HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings\
add a DWORD called "CacheTime" with value of "60"
then add "SuspendResume" as a string with "GPRS_bye_if_device_off"
obviously minus the ""'s

beware that tweak breaks simultaneous voice and data

I've never had any problems with it, when I have a 3g connection active I can make/receive phonecalls and keep the data connection live. I reguarly download files while on calls and they have finished by the time I hang up...?

What exactly does this tweak do?
I actually managed to configure the Hangup button to close the GPRS connection using the standard Button Settings menu, but I'm curious to know what your registry settings will do.

This will automatically disconnect the GPRS after xxx seconds (60 in the above) if GPRS is not used.

WiFi doesn't turn on after waking up from sleep mode

After upgrading to WM6.5, when phone goes to sleep mode, wifi turns off normally but after waking up, wifi is still turned off. It should start automatically. And I haven't find how to solve.
Does anyone know how to set it up? In communication manager, wifi is turned on, so I have to turned it off and on to start it. I tried searching in registry, but nothing about it.

I have exactly the same issue with the official 6.5 ROM. It's a pain everytime the device times out and goes into sleep mode.

Yes I have this problem too.
Dosn´t anyone here have a workaround to fix this problem?

it's normal behaviour - htc made it so wifi is set to automatically self-activate when access to the internet is attempted by an app

...but the problem is that it doesn't self-activate. If I'm using VNC, the connection is lost and I have to manually go into the connection manager and give it a push before it will re-connect.

Yes, but it doesn't work in all applications. For example, when some app uses only wifi for home use, it stays turned off. Some applications where it works display connection error before wifi is activated.

The only suggestion of a fix I've seen is to try a custom WM 6.5 ROM. I've not yet seen any registry fixes, although 'yet' is very much the operative word here.

Actually there are several registry fixes listed here. Try searching for 'wifi'.
The problem is that none of them work, either for me or others that have responded. I have tried all suggestions without success.
I have a Tilt2 but I think this is affecting all TP2 WM6.5 users. Is anyone getting good results?
What happens to me is when wifi is on the 3g icon is displayed. When the internet is accessed (either in a brower or the TF3D weather panel) the icon trys to change to a wifi symbol but then seems to fail and reverts to 3g. If I go to settings and turn wifi off then on the wifi icon displays and the internet can be accessed through wifi. If I let the phone go into sleep mode then it shows 3g upon waking.
