hi,

i have a problem in that i can get a dhcp address from my router to
both my LAN onboard NIC and my wireless nic along with subnet mask and
gateway. However i cannot ping the router.
I have connected my router to a laptop and can connect both ways using
wireless or a physical RJ45 connection.
I have tried using the netsh ip reset command to re-initialize tcp but
it doesn't make any difference. I have removed any firewall software i
have to see if this was the problem but nothing.
The only error i get is when a try to add tcp/ip protocol to a network
connection. The message is:

could not add the requested component. The error is: an extended error
has occurred.

Has anyone came across this before ?
 
assuming you have two NICs on the computer, do both NICs have default gateway? If yes, you may have a routing issue. posting the routing table here may help.

Robert,

I will post up a route print for you. However if i disable either NIC
and try to ping the router i still have the same issue.
The same setup works on my laptop with on board nic and wireless pcmia
nic.
I will check the routing table on both machines to see if there is any
difference.

thanks
 
Robert,

Here is a copy of my routing table

this is with just the nic connected.
