Hi, are there any computer wizzes out the that can help me out with a problem. I've had a Yakumo delta 300 GPS PDA for while now, but yesterday I got a Pluscom SDIO 802.11b wireless LAN card so I can get on the internet wirelessly via my D-Link ADSL2+ wireless router. So far so good. It,s hooked up to the net fine. In fact I'm using it now to ask this question. The problem that I'm having is that, when I try to read my e-mails on yahoo, explorer seems to switch off. I can get on yahoo home page and surf the net in general, but try and get on to my e-mail pages and it all goes Pear shaped.

Is it possible that the firewall inbuilt in the router is effecting it? The operating system on my PDA is Windows mobile 2003.

Can anyone help? Thanks.
