I just picked up a Netgear WGR614 v6 at a garage sale for $2.50.

I've read that by flashing the firmware with custom firmware you can convert certain wireless routers into wireless bridges.

Right now my PC is the only thing wired to my wireless router.
Is it possible to turn this WGR614 into a wireless bridge so I can finally eliminate this last wire?

Thanks for any advice!

 

You can flash it dd-wrt and then do this:

Or you might be able to use another firmware called Tomato - it's supposed to be easier but I don't know if it works on your router.
