PSP wireless connection, please help

[Spacehopper]

I have a 2MB ADSL line with a Wireless access point, which I use a wireless bridge to use xbox live, which works fine.
I'm trying to set-up my PSP to use the WAP but it won't work. On configuration it finds my network on scan and I enter my WEP code. When using automatic IP address (EASY) I get error code 80110482 on test connection.
If I put the IP address in manually, it then connects saying the signal strength is 1% and the internet connection failed, but when I scan for my network it shows a signal strength of 100%.
Any idea's?.

Try changing the channel number on your router to below 13. US PSP, if that is what you have, don't go above that. try that first and see what happens.
