I have a Zyxel Prestige 662HW-61 router which I use with an ADSL connection to the Web. I would need an outdoor repeater because of a concrete wall which prevents the waves from getting through. Any particular brand and model you could recommend at a reasonable price? Is the repeater multi-directional?

Max distance between repeater and router is 100 yds. The repeater would be used for one station only
