IE Network Problem

I have a Toshiba Satellite 2400 with a D-Link DWL-G630 Notebook Adapter in it. The card has set up and I have established a wireless connection to my D-LInk DI-524 wireless router. This show excellent signal strength. I am using WPA-PSK security with TKIP encryption. Icon on bottom right of taskbar say connection is OK but I can not get Internet Explorer to connect to home page or any web page on Internet. Also Outlook Express can't find email pop server - I have tried different email accounts with known working Pop Servers. Does anyone know why I can't get Internet connection.

My D-Link DI-524 via it WAN connection point is connected to Motorola SB4200 which is connect to Bigpond Cable. I also have a PC connect via 100BaseT to DI-524 and wireless bridge to my workshop where I have four PCs connected via a switch to other end of wireless bridge. All of these PCs can see each other and Internet with no problems.

Any ideas anyone???

 

I should have thought of that - trying to do too many things at once. It works with no encryption or WEP encryption but won't work with WPA encryption.
I think I'll leave it with 128bit WEP encryption on.
