Here is how mine is connected.
cat5 ethernet cable to WAN port on Linksys BEFSR41 router
Cat5 ethernet cable out of UpLink port on BEFSR41 router (other 4 ports empty)
to port # 1 on 16 port hub
all Windows 7 computers (x64 & x32), Xp computers, win98 computer, & any other test computers wired into ports 2 thru 16 of the hub.
But if you have 4 or less computers you can use the 4 ports on the Linksys
Hope this helps.
Did you get it for a good price ?
