I have an XB7 modem. About three days ago, my phone’s wifi icon had a little 6 beside it. When I turned on my HyperCube, which is on my 2.4 GHz wifi, it was off the network, so I had to unplug/replug to get it back on. Then, my computer’s wifi turned itself off. When I turned it back on, it popped up an announcement that I now had access to wifi 6. I checked my system logs and they showed no updates on my machine, so I’m thinking it was from a firmware update on my XB7. Does that sound right?
