jack is right, not much available in the way of a repeater
sucks huh?
i ended up running some cat5 and briding a wireless router/router as AP
how much signal do you get on the 2nd floor as it is? the mn-500 i have gives a fine signal in the half of the house its in on BOTH floors (it being on the lower)
the only reason i use an access point is to give a signal to the other side of the house. i didnt want to run cat5 all over the place, but one line for a bridge isnt a big deal
