Ethernet connection and DSL router

xasperated · Feb 21, 2014

My campus had wall-mounted ethernet connection. The wi-fi router has only DSL port for internet and four ethernet port which you connect to the pc.
It a Dlink wifi router.
Is there a solution which does not require me buying another router ?

Not really, though there are some routers that allow you to use one of the LAN ports as WAN. What model? Don't remember D-Link making one, though.

Solution to what? There is a bunch of exposition in your post, but no question!

I want to know the model number.

Some routers allow you to use one of the LAN ports as WAN. I don't think D-Link do any like this, but I need the model number to check.

Not clear what your problem is. What's the "My campus had (past tense noted) wall-mounted ethernet connection" have to do with anything? ditto for the "wi-fi" router - where did it come from, etc.?

A couple guesses:
1) You're now in a situation where you've got a DSL connection from an ISP. Plug the router (if it's from the same ISP) into the DSL, and your PCs into any of the 4 router ports.

2) You've got a single Ethernet connection to a local LAN and want to connect multiple PCs via the modem somehow. Remember that, in most modems like the D-Link, the 4 ports are actually a switch on the downstream side of the router, so you can, again, plug multiple PCs into those switchports, and ignore the DSL side altogether. You may have to disable DHCP in the modem to ensure that your local LAN address space is used for the PCs.

Many dense apartment blocks provide internet over Ethernet fed from a managed switch in the basement with fibre backhaul, with one public IP per port. Essentially, the router treats it like a cable modem.

So any old Ethernet router would work for that application, allowing him to build a small subnet in a private address space. Wireless, too if he wanted it.

Yup.

Unfortunately, his current router won't do the job. However, a new router should be <$50.

Or less... going rate for older routers is around $20 on that famous auction site.
