Before I got my brand new Sophos SG105w I used older Astaro ASG120v3, v4 and v5. Last one was a Sophos UTM120v5 with 2GB RAM and AN AP50.
With that setup I used 2,4GHz and 5GHz wifi simultaneously. For some reason the newer Sophos SG105w can only use one or the other band - not both.
As a matter of fact I can setup the SSID and tell this SSID profile to use "2,4GHz and 5GHz" but when I go under "Access Point" I have to chose one of it.
Plugging in my "old" AP50 This one offers me adjusting options for the 2,4GHz as well for the 5GHz band which I can enable and use simultaneously.
Any idea why the UTM software on the SG105w let me only choose between one or the other band but not enable both bands at the same time so far?
Or do I need another wifi card (i.e. the one of the SG135w which also supports "ac") to have this option? And if so WHICH cards are supported here???
