SAC2V2S is not broadcasting a 2.4 GHz signal
I've got a device that requires 2.4 G and it used to work fine. Now it will not connect to my network.
I checked the network for 2.4G and 5G signals with a wifi app and there was only one for 5G. When I restarted the router I saw a good signal on 2.4 and then it vanished after about a minute. The 5G signal remained. Looks like there's no way to access the router admin on this router. Does it need to be replaced?
