I’m not claiming this is scientific, but I ran several speedtest.net tests from my AX laptop through the MT3000 in WISP mode through the AX88 router. My ISP link is 200/35, limited by Cake to 190/30.
If I connected the laptop directly to the AX88, I got 190/31 on the Asus 5G band (essentially, full speed) and 108/29 on the 2.4G band.
If I connected the laptop to the 5G LAN band on the MT3000, I got 185/30 with it connected to the Asus 2.4G band and 135/30 on the MT3000 5G band.
If I connected the laptop to the 2.4G LAN band on the MT3000, I got 17/12 with it connected to the Asus 2.4G band and 59/29 with it connected on the Asus 5G band.
So essentially full speed connecting to the 5G on the MT3000, with the WISP connection on 2.4G, but I sort of expected the same with the WISP connection on the 5G band. The 2.4G WISP connection is actually worse than my Mango at 22/18.
I did these from default, setting only the admin password and the SSID details for the Asus.
I took the MT3000 down to the public library to test on their 5G AC wifi. Connecting directly with the Yoga, speedtest reported 135/158.
Connected to the MT3000 on the 5G band and the MT3000 to the library wifi gave me 12/49.
Connected to the MT3000 on the 2.4G band and the MT3000 to the library wifi gave me 24/50.
Obviously, at any given moment I don’t know what other traffic was being handled by the library wifi.
