I’m having the same issue as well. We were recently upgraded to 5GHZ and so I separated the 5 and 2.4 connections as individual connections but cannot see the 2.4 connection. I called Swisscom and we disconnected, restarted, rebooted, etc but the problem still remains. I also have a guest WLAN connection set up but cannot see that connection either. So, now all my devices (incudling my printer) that only connect to 2.4 GHZ won’t work wirelessly. Any ideas on how to have the 2.4 GHZ connection show? Thanks.
