G54 5GHz networks can't be detected. I set up a G54 modem in my home in November, and configured my wifi networks using Split Mode. I had most of the devices connecting to the 5GHz network perfectly fine for a while. They were routinely getting speeds in the 400-500Mbps range. Then suddenly a couple weeks ago none of the wireless devices in my home were able to detect any of the networks except for the 2.4GHz one, and they were only getting speeds of ~50Mbps. According to the modem’s Admin GUI the 5GHz radio, 5GHz High radio, and 6GHz radio are all enabled and active. I tried a factory reset and turned Split Mode back on. Once again, my wifi devices could only detect the 2.4GHz network. I then disabled Split Mode and enabled Band Steering, hoping that they would get automatically directed to the faster band. But the Connected Devices page showed everything connected on the 2.4GHz band, and speed tests showed I was only getting ~50Mbps on that band. I tried enabling the Guest Network with the same results. I have a desktop
