Hi, I wonder if anyone can help me with a problem I have with my broadband at the minute. I have a wireless broadband router from Eircom, that I connect directly into with my desktop via ethernet port and wirelessly for laptop.
The laptop will contact the DHCP service on the Router (WiFi) and get a valid IP address within the scope set on the box 192.168.1.x. My desktop (LAN), however, cannot seem to pick up an address automatically - if i renew the ip address it always comes back with a 69.x.x.x number (always the same). This has just happened recently - up until last week it was working fine. Even if I hard set an ip address to 192.168.1.x, I can ping the router, but cannot connect using http or telnet.

Any ideas.
Thanks
Jon
 
Ive seen this before and get it when connecting my work laptop to my office network after Ive had it connected my home network.

The 69.xx number is an internal IP that your network card is assigning itself. The fastest way to resolve this is to go to network connections, disable your LAN connection and then enable it, it should connect to the router then.

Renewing just reconnects the PC back to the 69.xx address.

Someone else may know the root cause.
 
Thanks Car. Unfortunately that didn't work at all. Plot thickens a little -- I have an old a Cayman 3300 router that doesn't have wireless, but has a USB connection. When I connect up via USB, I get the same result - IP address doesn't come from DHCP on router, but another 69.x.x.x address.

Any others ideas anyone?

Thanks
Jon
 
If you don't get anywhere fast with that problem then perhaps try resetting your IP stack with winsock xpfix http://www.snapfiles.com/get/winsockxpfix.html

Be prepared however to re-install any other software that uses your tcp/ip stack such as firewall, vpn software etc.

I'm assuming of course that you're running xp.
 
did you do an ip /release and then ip /renew - sorry I know you said to renew, but did you release first? Just a thought.

Thanks Wishbone, I got this sorted out last night by uninstalling McAfee. I installed AVG free AntiVirus instead and all is good.
