I have a PDA running Pocket PC 2003 and a wifi card. I have been able to connect to several free wifi networks (eg in hotels) here in the UK without any problem. However, I have never been able to do the same abroad. My PDA can see the network I am trying to connect to, and acts like it is connecting, sometimes even saying 'connected', but I am never able to view any web pages. Sometimes I have had an error message about my IP address.
Anyone got any ideas? I know that some hotel networks may require you to use a WEP key to connect to their network to prevent unauthorised use, but I have had the same problem trying to connect to the free wifi at the Sony Center in Berlin, where access is free for all.
