Here is the problem. I have one router (Thomson TG585 v8) and two PCs connected to it with ethernet cables. What i want to do is to monitor the traffic of the second computer from the first. Is wireshark the tool i need and if yes how exactly am i going to do that ? Thank you in advance.

It's unlikely that you'll be able to capture the traffic you want with your current setup as I'm pretty certain your router is a switch

See here for info on capturing on switched networks.

Thomson router have a facility called port mirroring which will turn a switch port into a 'monitor' port. You can only monitor a single port. If you google 'thomson router port mirroring' you may get a PDF of the commands to set this up from CLI/Telnet.
