I looked at the specs and working from a table of wifi bandwidths, I was able to infer that there is no 160MHz support and no DFS support.
5GHz band 1 mentions 866Mbps which is for 2x2 MIMO and 256QAM for 80Mhz channel.
5GHz band 2 mentions 1733Mbps and 4x4 MIMO, which should be for 256QAM and 80Mhz channel width.
I tried to find the FCC ID. I looked up wikidevi and then the FCC report and does not appear to be certified for DFS channels.
Still wondering about WPA3. Anyone have experience with this device?
