I got the Cirrus today. Reinstalled the latest firmware and set it up with Mullvad Wireguard.
What disconcernes me are the WiFi speeds.
Next to the Cirrus I get 50-55MB with Wireguard. Only 7meters away through a wall, the speed is down to 2-3MB.
This is on the 2.4GHz band. Tested with an iPhone.

These speeds are no better than with my Slate750s. I hoped for improved speeds and range. But in my case it just cost much more, is not portable (big and heavy) and delivers less speed …

Will this improve with firmware updates? I hope so, but I‘m afraid not.
