Anyone got any old routers they don't want? Preferably n speed wireless? Maybe even if it's playing up/ a little dodgy I may still be interested. Not looking to spend a fortune just looking to extend my wifi network.

I have a netgear 3g router, no psu free to a good home

Got a working Netgear WGR614 here for a fiver.

Its listed on DD-WRT so you can mod it
