We have a wireless gateway. It's an Arris. Our laptop picks up the signal some of the time and our 2 smartphones pick up the Wi-Fi sporadically. We have tried everything from unplugging everything 1-2 minutes, hard reset, getting a refresh signal, and having a tech out. When the tech was out he found low signal and supposedly fixed that. We have to reset the gateway maybe 4-5 times a day and if we are lucky, it works off and on for a few hours. We had another Arris and it would just quit broadcasting the signal. Also have a Roku that can't pick it up. Had a SMC wireless gateway and it worked fine for years and finally crapped out. Any help would be really appreciated.--Thanks, Andy
