Belkin router - can I use this for a network hub?

I need a couple of spare LAN ports for a little project, but I'm using all 4 ports on my Spark Technicolor Modem.

(I thought I had a spare network hub lying around but I must have tossed it when we moved, durnit!)

So I'm wondering if I can patch a Belkin router into my home network to add a few more ports.

A neighbor found it at the local recycling center and passed it onto me.

It's brand new in an unopened box, but it's a bit of a dinosaur because it's just a router, not a MODEM\router.

Not particularly useful these days, which is probably why someone dumped it.

It's also wireless. Full name - Belkin Wireless 802.11G Router. A sticker says it's 'ver.6003au'.

My question: I'm guessing I can just patch it into my network, and I think it'll act like a hub.

But I'm not quite sure what'll happen if it starts beaming wireless signals around my house. My four notebooks might freak out.

I'm an PC service guy (retired) and I feel I ought to be able to sort this myself, but I've never run across this situation before.

Helpful advice would be much appreciated (8-))
