repeater

have a yagi antenna connected to a (ddwrt) wrt54gs router. picking signal from my brothers house on the hill (with permission).
how do i hook my other router wrt110 to the linksys to distribute signal wirelessly in the house?

yes, do as a wireless repeater ~.~

Plug one end of an ethernet cable in to the port on back of the wrt110 marked "Uplink" and the other end into any of the unused ethernet ports on the wrt54. There may or maynot be some network settings to adjust. I am certain their are other threads in thes forums that address this.
