Poor WiFi signal in small home
I have a 2Wire HomePortal 3801HGV residential gateway. My house is a 2000 square foot single family wood frame home built in the 70's. Is it unreasonable to expect my U-verse system to provide a reasonably strong and dependable WiFi signal throughout my relatively small home without supplementing the system with the addition of WiFi extenders or similar efforts? Prior to U-verse, and prior to the 2Wire HomePortal 3801HGV, I enjoyed a reasonably strong and dependable WiFi signal throughout my home from an unsupplemented wireless router installed in virtually the exact same place in my home.
I am now on my second U-verse residential gateway as the first one was destroyed by a lightning strike. Neither U-verse residential gateway provided a reasonably strong and dependable WiFi signal throughout my home.
I have already changed the WiFi channel from the auto/default channel, channel 9. I have tried both channels 1 and 11 without seeing any noticeable improvement.
