Limited Connectivity

[PeterSK]

I've just brought my laptop (running XP pro) back from university, where the
internet worked perfectly fine. Now I've hooked it up to my home network (3
computers connected to a router, connected to a dsl modem) and suddenly I'm
getting a the limited or no connectivity message and cannot access the
internet at all any more.
I've tried repairing the connection, which falls at the first hurdle by not
being able to renew my IP. I've done an ipconfig /release and /renew to no
effect. I've tried different cables and different ports on the router, which
again did nothing. I've also tried deleting and reinstalling my network
drivers and even the network connection itself but still no change. I even
did a complete format and reinstall of XP, but yet again nothing changed.
I'm completely stumped, if you have any ideas whatsoever I'd be really
grateful.

Try this:
= Click Start >> Control panel >> Network and Internet Connections >> Double
click Network connections, then right your LAN Icon and select Properties.
On the LAN properties under General make sure the Internet Protocol TCP/IP
is selected and click Properties.
There make sure the Machine Get assigned Automatically IP address and Renter
the Encryption Key and the Network SSID then click
[OK].

= Click start >> Control Panel >> Double Click Network and Internet
Connections >> Double click Internet Options, on the IE Properties window
you will see these Options:
General | Security | Privacy | Content | Connections | Programs
| Advanced.
Click on Connections tab and make sure the Connection is listed there then
click on LAN settings button and uncheck Automatically detect settings.
Click [OK] and close Hit F5 and open a run command and type in:
ipconfig /flushdns click [OK]
ipconfig /renew click [OK]
netsh winsock reset click [OK]

Download the winsock fix from here:

Reboot your machine.
If that didn't help try to upgrade the router firmware to the latest version
from the router Manufacturer website.
