Hi,
my Flint 2 - Firmware 4.5.8 and 4.6.2 was initially configured with the following WiFi settings on 5GHz:
Channel: 116
Channel bandwidth: 80MHz
Wi-Fi mode: 11ac/ax
After an uptime of around 3 days I noticed that my channel bandwith was reduced to 20 MHz (according to WiFiMan).Therefore the download and upload speed was capped at around 200Mbit.
The channel was also changed to 100, which looks like DFS kicked in.
I can understand the switching of the channel, but why would the channel bandwidth get reduced by DFS? I never saw this behaviour with other routers.
