hi, i have a desktop pc and a broadband connection to internet.it is working good. i have bought a new acer netbook, with win xp,SP3. whenever i try to connect the LAN cable to this, it shows the msg, limited or no connectivity. what is the reason? i googled many times. did these things..bt nothing helpd 1. disabled and enabled the n/w adapter 2. changed the duplex modes(10 Mbps/full,10Mbps/half etc.) 3.set the ip manually and tried.then it showd 'connected'.bt no use... 4.the ip is automatically setting as 169.254.x.x now tell me, what can i do?

The error means you are not actually talking to your ISP's servers. Your IP address verifies this. Try in this order: 1. Temporarily disable your software firewall (ie: Norton, McAfee, etc.) Then plug in the cable. If Internet works, your firewall settings are wrong. 2. Reset/power off and on your modem. 3. Ask your ISP if they have a MAC address-to-IP assignment policy. That means they only allow one registered computer to work on the Internet unless you re-register the other. NOT convenient in this case - get a router.

Maybe it's caused by corrupted winsock catalog, you can test to use winsockfix to fix it.

I've encountered this problem before when i formatted my drive and installed windows xp sp2, the solution I did was, 1. Go to network connections, then right click on the LAN icon, then go to properties. There look for Internet protocol (TCP/IP). 2. Click it then go to properties check obtain the following ip address, then input any ip you want (example 192.168.0.2), subnet mask do the same (255.255.255.0), default gateway (192.168.0.1) 3.For the DNS server do the same as ip (example 192.168.0.1) that's it, it worked for me may it will work for you.
