Hi, The internet connection in my house is only decent in the roooms immediately connected to teh hallway where the router is situated. It isa very old house with thick walls. The connection upstairs is particularly bad. Any suggestions?
The best solution is to drill some holes in walls and ceilings in order to install Ethernet cabling (cat 5e or cat 6), best terminated at RJ45 wall sockets. Some floorboards may have to be lifted upstairs. For most people, hire an electrician or builder to do this.
