I need to set up a wireless network for my flatmate so she can share my cable modem connection and I'm hoping I don't have to purchase any additional equipment. My previous internet connection was via DSL, but I've recently switched back to cable - and forgot that the DSL gear doesn't use ethernet for the 'in' connection :-(

Here's what I have.

1. A cable modem - coaxial into the modem and ethernet into my iMac (it's a new one with 802.11n)
2. A Belkin ADSL Modem with Wireless-G router

Now I know I can share my internet connection wirelessly via Airport on my iMac - but I'd very much like to not have it on all the time. Is there any way I can route the signal into the ADSL modem and then broadcast that for my flatmate and her laptop - or is it time to buy either a cable modem (or perhaps a Time Capsule)?

Thanks for your help!

If your DSL modem accepts ethernet and can be configured to act as just a router only (not a modem), then it should work. If it doesn't, then it won't, and you'll need a stand-alone router, such as a Linksys.

Probably not, buy you can probably get more for the ADSL modem/wifi on eBay/similar than it costs to buy an 802.11g router.

Thanks for the top tip. I haven't completely sussed it out, but I did as you suggested.

I plugged the ethernet coming out of the cable modem into one of the ports on the ADSL modem/router. I then turned on my iMac's airport signal and connected to the router. I opened the WAN connection config page for the router and I ignored the usual setup assistant and enabled the 'router', entered the DNS numbers for my internet service and was instantly able to surf the internet via the Airport connection.

I reckon the next step is to set up the wireless encryption, but I'm just chuffed that it actually works as it should.

Thanks for the help!

It sounds like you have it figured out! Great job!
