Can i set up my old router as a wifi receiver?

Hey everyone,

I have an iMac thats out of warranty and the airport is dead or something.

Is it possible to use my old 'Netgear WGR614 v6' as a receiver for my wifi and connect it to my computer using the ethernet port?

I've tried reseting to factory settings. Can't get anything to work.

I have a PC hooked up in my house so maybe i can fix some settings there?

All the tutorials i've seen around show hardware specific things. So i'm not sure if mine is compatible.

If someone could help me out that would be awesome!

Thanks in advance =D

Seb
