I was on my home network for three months. All devices. I added a Range Extender this Monday as the modem is behind adobe wall and signal was not fast. Now my tablet can connect to the 5 MHz but the laptop and the new smart TV cannot find the wifi address with the 5 MHz it finds the 2.4 MHz and that has no speed to connect.
