I have a new client that has a rather large home. Due to the construction of the house, running ethernet is not an option. The husband and wife each have offices that are on opposite sides and different floors of the house. Currently they have a Linksys router attached to a cable modem in one corner of the house. The wireless signal barely reaches the other corner of the house on the same floor, which is their family room, but I need to get a signal to the husbands office which is in the basement below that. I've got a DLink signal booster/repeater I am going to try, but I'm not really liking the idea as its another device to sit somewhere and when they lose power I don't want them to have to mess with it. Are there any suggestions? I see some of the newer routers have 3 antennas and claim to be more powerful and designed for larger homes/offices, but I'm not sure if this is hype or not.
