Internet Box 3 is dropping the WLAN connection for OS X (Mac)

Level 1
1 of 4

I have several computes and tablets and the home network consists out of Internet Box 3 and 2 x WLAN-Box 2. While the window PC's and tablets are working without any problem, I have repeatable problems with my Mac computers. 


While working (or being idle) the Mac is dropping the connection (WLAN) several times per day and the only way to solve it is to re-start the machine. To do some RCA, is did a full new install on my MacBook (Big Sur) and no applications added. Still the same problem exists. 


Divide the 2.4 and 5 GHz channel (they had both the same SSID) did also not help.


I do have also the Internet Booster connected, this connection is also dropped (about once per day) and only "power cycle" (switch off and on) both the Booster and the Internet Box is resolving this issue.


Is this a known issue? Are there other things I can/should check (I already switch off IP6)?


Any help is very welcome.


Thanks, Victor

thanks for the contribution


The problem sometimes exists with new versions or beta versions MacOS / Apple

by example  MacOS Big Sur 11.2.3 -> 11.3

MacOS Big Sur 11.2.3 and 11.3 - Swisscom Community


they have more recent technological rights, which are not 100% compatible with all functionalities

be patient until the updates which should not delay
