802.11AC Requires more rates than we support

Hi, I just got a SXT G-5HPacD and tried to configure up to a wireless AC network as a pseudo bridge (client) but it doesn't seem like it ever connects, so I checked the logs, and find this after I enabled wifi logs:

00:13:34 wireless,debug 10:7B:EF:7D:02:71: on 5180 AP: yes SSID Hemskanseaasen5-5GHz caps 0x111 rates 0xOFDM:6-54 BW:1x-4x SGI:1x-4x HT:0-23 VHTMCS:SS1=0-9,SS2=0-9,SS3=0-9,SS4=0-7,SS5=0-7,SS6=0-7,SS7=0-7,SS8=0-7 basic 0xOFDM:6,12,24 BW:1x VHTMCS:SS1=0-7,SS2=0-7,SS3=0-7,SS4=0-7,SS

00:13:34 wireless,debug wlan1-gateway: 10:7B:EF:7D:02:71 requires more rates than we support

I have tried to change the VHT MCS that is supported under datarates in winbox, but nothing seems to help.

The access point i'm trying to connect to is a zyxel p8702n. Can't adjust much on it because it's my ISP that is controlling it.

Is there anything obvious that i'm missing?
Thanks for your help

Hi BinaryPaws,
if the client doesn't associate means that it cannot negotiate the same BASIC RATES, therefore check what you have checked in WinBox, ask your ISP what they have on the other side and match them.
Once the AP will connect you can check SUPPORTED RATES to avoid rate flapping, anyway I ran a big WISP with hundreds of devices and I never needed to change BASIC and SUPPORTED rates from the default ones.
