Question

now it sais u have sumone using the same ip adress or network as u and now both comps do work help:

Answer 1

try changing the names of the computers first. then try this...
turn computers off
unplug router and modem from the back not from outlet

plug modem in and wait 5 min
plug router in and wait 2 min
turn computers on

Answer 2

you need to assign a separate ip for each machine , either like 192.168.1.100 then go 101 for a second system, etc 103 for third and so on, make sure the net mask is the same, it is safe to use 255.255.0.0 or common 255.255.255.0

Answer 3

Enable DHCP on the Router and both computers

Good Luck

Answer 4

both the computers have the same ip address. u need to go and manually assign different ip addresses.
