Rich has a room about 35 feet away from the base station, and they have issues with dropouts from it. Leo says that WiFi is a line of sight technology, primarily, and so anything that goes in between the access point and the device can interfere. One way to solve the problem is to put your access point higher up the wall. That will move the signal away from a lot of things that will get in the way.
Another option is to get a mesh router or even go with Powerline networking, which uses your electrical grid to network from your router to that room. It's gotten a lot better in the last few years. Leo says that TPLink is the best manufacturer for it.
