Hello all.
So, having moved into my res. at uni, I'm now trying to install my computers. I have one jack in the wall, and two computers. No wireless.

the university bans me from having a DHCP server.

If i plug one computer into the jack, I get internet. So I got an old router, Linksys BEFSR41, and enough patch cords. I configured it to disable DHCP.

Here's the problem; how do I make it run as a hub, i.e. plug my laptop and desktop into it so that they both get internet? I've tried everything and it doesn't work.

Thanks.
I like pie.

does your PC have two ethernet ports?

If so, you can do: wall socket -> PC -> Laptop, and bridge the connections.

why you just run a private network? It's what I did for a while, they didn't really care.

For that, just use the internet up link port on the router

Anyway, as long as you have DHCP turned off, just plug it into any of the normal "computer" switches. That should just distribute it like a hub...
(at least, it worked like that for mine)

Or, read the manual for the linksys, i'm sure they tell you how to do it....

if you can somehow register a router on your network, you can set it up with dhcp no problem, as long as you know how make sure your dhcp service isn't broadcasting across your campus network.  port blocking is essential to this.

but the easiest method would be jenspm's suggestion of just bridging the connection from the other system.  (there is a performance hit on the machine hosting the bridge)

I got it to work: using port 1 as input, 2 and 3 as output. No idea why. Thanks all.

I would guess because you wall connection isn't actually just an internet connection but a true network connection to the Uni network.

Ha, I happen to have a BEFSR41 lying around. POS IMO, get a cheap switch for this purpose.

Anyways, the reason it didn't work at first is because I guess you were using the "internet" port. Technically, that "home router" is a router and a switch. The router has two interfaces, one of which is hardwired to the four port switch. By the definition of a router, each interface has to be in a different network. So, when you plugged the wall in to the Internet port and your computers in to the switch, they were in a different network and couldn't make magic because the router doesn't know how to route between them.

I don't think you can on the BEFSR41 because of the Web Admin limitations, but you could certainly configure a router to work in this situation. However, that wouldn't be worth it unless you need all four switch ports which you don't seem to.

Edit: Slight addendum, nothing practically important: You said you wanted to use it as a "hub." A hub and a switch are two different things, a hub sends a packet it receives on port A to port B, C, and D regardless of where the packet is going. It's rather dumb. A switch records the MAC addresses of machines as they traverse the switch and then send a packet out only port C if that is the connection to the receiving machine. Switch > Hub
