Huawei Versatile Routing Platform Software

VRP (R) software, Version 5.170 (AC6508 V200R010C00SPC500)

Huawei AC6508 Router uptime is 0 week, 0 day, 22 hours, 50 minutes

3.  AP is AP7060DN 

4. we checked display radio-5g-profile/radio-2g-profile name profile-name command on the AC to check the radio type. The command output shows that the radio type is 802.11ax.


5. Check network adapter driver information on the STAs such as PCs and laptops.  and the driver version is earlier than 20.70.0.

Root Cause

The Intel network adapter driver of an early version cannot parse the Probe Response frames that carry the 802.11ax protocol field.

Solution

Switch the radio mode to 802.11ac or 802.11n in the 5G or 2G radio profile on the AC. 

 [AC-wlan-radio-5g-prof-default] radio-type dot11ac

 [AC-wlan-radio-2g-prof-default] radio-type dot11n

Suggestions

Upgrade the Intel network adapter driver of the STAs to 20.70.0 or later
