XDA11i Wifi problem

Hi,
I have dug out an old XDA11i for wifi use at home. The problem is that I can connect to my SpeedTouch wireless router when I turn off all encryption, however as soon as I turn it back on (WPA-PSK) I am unable to connect.
I have done some research on here and other forums and it seems like it was quite a common issue. I have tried all suggestions:
Hard reset, turn off all encryption, connect XDA then add encryption one step at a time then configure the wifi profile on the XDA etc..but I still cant connect.
I dont want to leave my Wifi network unprotected. I have a xbox 360, xbox, laptop, pc and HTC wizard all running on Wifi without any problems.
Can anyone please help me get the XDAii working.
Thanks
I guess no one can help?
managed to get it working myself after some trila and error...
1.Turn off all encryption
2. restart router
3.clear ppc wifi profiles
4. connect without encryption
5.add wep 128-bit encryption (not the best but better than uncrypted)
6. add wep key to ppc.
All connected fine..
my solution is try to MAC address filter the device that you connect to Wireless router.
so that you don't need any protection at all.
I'm using that way so I just need to register my PDA MAC address to the Wireless router and it can connect so well now
I had the same problem with my Fritz!Box 7170. I solved it with disabeling the function "receive IP adress automatic" and gave a fix IP adress. Now it works fine.

[Q] wifi connection problem

hi...before anyone say anything first, I had my wifi problem whenever there is blackout in our area, then I cannot connect to wifi but my sisters can connect they use iphone and laptop. whenever I will connect it shows " obtaining IP address" then it will be disabled and it will say disconnected and I cannot connect to my cousins wifi too but I can connect to my work's wifi...I already factory reset it many times but now I'm having problems with that too...please help me...
Try rebooting the Wi-Fi access point your trying to connect to, I have to do that to my Buffalo Wi-Fi router from time to time and then the phone will connect OK. Its worth a try.

WiFi connected, cannot ping the home router

Sometimes I am connected to the home network but with no internet access.
In terminal I tried to ping my router, but with no success. I can use wireless home network/have internet access from other devices at the same time.
If I turn off WiFi and I can reach the internet by mobile network.
Looks like the phone thinks that it is connected to the network but it isn't.
I have solved the problem by forgetting the network and afterwards connecting to it again, but I would like to know why and how it happened.
