It might be helpful to lean more about WiFi coverage in the house.  There are "Heat Map" applications for many platforms which allow the user to walk around and record WiFi signal strength at various places.  After being told, "the WiFi is not very good in the bedroom", I installed WiFi Heat Map (by Webprovider) on an Android tablet.  Walked around the upstairs and recorded this:

No more complaints!

p.s. I find the ENORMOUS X's marking where readings were taken annoying.  But, it is a free app.
