My users can connect with their laptops on our wired connection. When they go on the road and try to connect via wireless in hotels/airports etc the wireless connection connects, gives them a local IP address etc. yet they are unable to get any webpages to load. I've even had them try to use the IP addresses of websites (in case it was a DNS issue) with no luck. Any ideas on this one would be appreciated.
Software/Hardware used: Windows XP SP3, Dell Laptops
