However, I read some reviews where people were complaining that the speed degraded all the way down to 20mb instate of the expected 100mb. This id due to the distance in wire the signal has to travel through out the house.
The reason I asked for the router model is that you might be able to use a wireless repeater (ex. D-link DAP-1522), rang extender (ex. DAP-1360), or DD-WRT Open Source router (ex. Linksys WRT54GL).
