I just reconfigured my wifi network and replaced an old AE thinking that it might be the trouble. I hard reset my time capsule which is not used for back up as well. Airport Utility recognizes both devices and all should be right. However, I experience a drop in wifi coverage in the room that the AE is in (very slow page load times etc.). What am I doing wrong? Coverage should be seamless and used to be for years. Any help will be appreciated.
