Does anyone know where to get a relatively cheap, yet functional wireless repeater? Its only temporary until I get the ubiquity unifi routers next year.
Depends on your definition of cheap... I've used a Fritz! repeater and an ASUS RT-N53. They're around the 60€ mark...
the wrt-54g with dd-wrt is my go-to cheap wifi device. $5 at any thrift store or free from a friend's basement.
