I just moved to a new house in an older neighborhood with lots of brick walls. After getting internet installed yesterday and setting up my router, I walked around the house testing the signal with my iPhone. Right next to the router, I get about 25 Mbps. Most other places in the house I get between 20-25 Mbps. There is a single room, however, where I get about 1Mbps. It happens to be the room that is at the furthest possible point from the router, which also happens to be my office - a room where a good internet connection is critical.
Would this be a situation in which a repeater would help? My understanding is that they are most useful in extending the effective range of a wireless signal, but I'm not sure if effective range is the issue or not - my wireless devices in this 1Mbps room claim a roughly 75%+ strength signal. Moving the modem and router is unfortunately not an option, so other than using a repeater, I'm not sure that I have any other options.
