I'm in the UK. I just bought a US Robotics MAXg wireless ADSL gateway plus matching MAXg PC card for my Win98SE laptop, a Thinkpad T22. The gateway's configuration page says it has an Internet connection, and the right lights are on. The PC card seems able to see the gateway, and gives a bar graph of link power. ZoneAlarm Pro knows there's a new network. Unfortunately, the rest of the computer doesn't believe them. Browsers don't browse, e-mail clients say they can't connect to the server. This happens whether I'm using WiFi or a wired connection.
Please, what else do I need to set or change?
