Hi, I've used my airport extreme card no problem with a wireless ethernet connection but I am now having problems setting up the card to use an alternative one. I can get signal from the wireless base station, which is an ntl one i think: http://www.ntlwireless.co.uk/routerspec.htm I can see a good signal reception. However, I cannot actually use the connection: An error message appears telling me that Safari cannot access 'the server.' I believe my problem might be that Airport cards have a fixed IP number which is preventing the DHCP server from allocating it a number, which I believe is how most wireless networks function(?) Changing the settings to set the IP address manually does not seem to help. Any ideas anyone? Am I just being stupid and missing something obvious like needing to register with the ISP? Thanks!
