neilhaha -> Failure in "renewing your IP address" - any ideas? (1/6/2007 17:30:11)

So here's my problem
I recently bought a new Advent 8111 laptop with Intel PRO/Wireless 3945abg. I'm trying to connect to my NTL broadband via a Belkin54g wireless router but keep getting failure to establish wireless connection .with error "... following action cannot be completed: Renewing your IP address."
I can connect happily with my old laptop to the same router [hence posting this!] using a Cisco 350 series WLAN card - but not the new one?

What I've tried doing ... without success ...
Turned the WLAN hardware switch ON [;)]
Run IPCONFIG /RELEASE and RENEW
Compared settings on new laptop and compared to old > the same
Switch on/off laptop, router
Scoured the internet

Any ideas? ... gratefully received

Have you tried disabling any firewalls you might be running?

Also, sometimes uninstalling and reinstalling the network card in Device manager can correct connectivity problems.

Also disable any security you have and see if you connect.

Have you already rebooted your router?

Are you running WEP or WPA? Check if your key is right. You also might see with the wireless router can run DHCP.

Thanks for all the suggestions - finally found out what's going on... [:)]

Swapping computers on the cable modem
Most domestic cable ISPs (including NTL, Blueyonder) have the cable modem configured to recognise only one client PC, by the MAC address of its network interface. Once the cable modem has learnt the MAC address of the first PC that talks to it, it will not respond to another MAC address in any way. Thus if you swap one PC for another (or for a router), the new PC (or router) will not work with the cable modem, because the new PC (or router) has a different MAC address to the old one. To reset the cable modem so that it will recognise the new PC, you must power the cable modem off and on again. Once the cable modem has rebooted and gone fully online again (indicator lights settled down), reboot the newly connected PC so that it makes a DHCP request, or manually make it request a new DHCP lease.

I found this a really helpful website for explaining to a novice like me how connectivity works ... or doesn't! > http://homepage.ntlworld.com/robin.d.h.walker/cmtips/index.html

A simple reboot fixes quite a few problems.
