Hey everyone. I just moved off campus about a week ago. When I moved I networked my laptop and desktop together with my hub. At that time I could connect (both through remote desktop and just by typing in \\<computer name> ) to my desktop from my laptop, and the other way around. Since I got my cable moden I can't see the desktop from my laptop, and vice versa.

I hooked the modem to my laptop first, just to see if it work connect to the internet. it did. They I hooked it to the uplink on the hub. again my laptop could connect to the internet. However I couldn't reach my desktop. I've tried everything I know including setting up the same workgroup on both computers, still couldn't see one another. If I disconnect the laptop from the hub my desktop can't get internet ( can't get internet with the laptop is connected to the hub either) does anyone have any ideas? Thanks for any help. Also, there wouldn't be a way I can grab files and share files to the campus network without actualy being connected to the campus network is there? Thanks!

It's probably that the modem is only allowing one computer to connect. Since all a hub does is forward packets, the modem sees both computers and only allows one to conenct. If you get a router, the router will take care of everything behind it, and the modem will only see one "computer" - the router.

You need a router to share one IP address to the internet.
Your modem gets one IP that is passes to the computer connected to it.
If you use a router the router gets the IP from the modem, and all your PCs get an internal network IP.
A hubs uplink port is to connect the hub to another hub.

You can use your computer as the router if you have 2 network cards.
You'd connect the PC to the modem and the PC to the hub.
When you connect the laptop to the hub you should be able to see the PC and you can share the internet thorugh the PC

No IT blocks any external access to Windows File Sharing from out side the network. Plus sharing certain files would be illegal.
