How do you connect 2 computers via a router ?
- One desktop computer with Windows 7.
- One Laptop with Windows 7.
- One Wireless Linksys router.
The purpose really is to interface the two computers to enable multi-player gaming.
(Not sure what exactly you're after, as your question is ambiguous)
Use ethernet cables, with the router in between...
Desktop PC -> Router <- Laptop
Plug in the ethernet cables between the router and the desktop and laptop, and they will be connected, you will have a Local Area Network where you can transfer files, etc, even without the internet.
