Hello- I am struggling to get my house set-up properly for a strong wireless signal strength. I could use some advice. My current set-up includes: - A 2Wire gateway broadcasting wirelessly at 2.4GHz (b/g) - A Time Capsule connected to the gateway via Ethernet and broadcasting wirelessly at 5GHz (n). My signal strength is very poor in some portions of the house. Most noticeably where I need it the most... My media room (which has the Apple TV, PS3, etc.). From reading posts here, it appears I have the following options: 1) Get an airport express and use it as a range extender. 2) Get a power line home networking device and hook-up my devices via Ethernet. I would appreciate any suggestions on the proper way to go, and, if there are any other things I should try besides what I listed above. To help, I have attached two images: The first is the layout of my house and the second is my signal strength. Thanks again!
