RB SXT G-5HPacD "requires more rates than we support"

Sun Mar 15, 2015 12:36 am

I am unable to connect my SXT SA5 ac as a client station to my Netgear R7000 access point. I created a wireless, debug log rule and am seeing the below messages which indicate some type of issue with the beacon frame requirements from this AP while running both the latest stock and the latest dd-wrt firmware. Is there a change I can make to either the AP and/or station to allow them to connect with each other?

[MAC] on 5745
AP: yes
SSID [SID]

Maybe you can try lower the HT Basic MCS on the Mikrotik AP? I think that should work.

I'm having the exact same problem... I've tried editing the supported/basic rates on my SXT and changing every setting I can think of. I can't seem to resolve this issue.

i think

if you are using default datarate and mcs configuration, maybe you need to find the solution on netgear side

I've tried changing all the settings available on the netgear router. It doesn't seem to have an effect. Phones and laptops connect fine to this router. I suspect the issue is on Mikrotiks end.

Thank you very much for letting us know about this issue!

Fix will be included in one of future RouterOS release such as 6.35rc14/6.35rc15.
