How can I use an Asus WL-520GC router as a bridge/repeater?

Question

I live in a shared accommodation with one Internet connection, which is shared to multiple PC's though a wireless network.

Because the wireless router is at one end of the house and my room is at the other end, my computers and mobile devices have trouble picking up any signal.

What's the simplest way to fix this?

I had thought of putting my own wireless router - an Asus WL-520GC - half-way between the main router and my room. Perhaps it could relay the signal to my room.

Is this possible and how can I do it?

Solution

In case you have an old unused router, you can check if its firmware supports any of following modes : wireless repeater, bridge or a client mode perhaps.

In case it doesn't work, next best solution would be verify if you can install custom firmware like tomato or dd-wrt. Here you can check if dd-wrt supports your router.

Third least expensive solution would be to try buying used router which support dd-wrt or maybe tomato.
