router interface problem

Could some one please advise i have a US robotics wireless router
model number 8054, i have three pcs connected by ethernet and one
laptop wirelessly. i am unable to get the web interface up to change
options and only one pc is able to go on the net, but two pcs can see
each other and their files. any help appreciated. TIA

A possible cause is that your PC's are not all on the same network and
the router interface is on the same network as only the one that has
Internet access?

Have you checked the IP address, subnet mask and default gateway of
all the PC's? Start by taking the details of the PC that has internet
access and then make sure that the sub-net mask and default gateway of
all other PC's is the same as that. The IP addresses should differ by
say one in the last number only and that number should be between 1
and 254 (!).

If you don't know what I am talking about, post again and I'll give
more details.
