Network Management

Under Clients -> Connected I can see channel width column. Many clients show VHT80, but when I click on them Airwave shows:

Channel Width: VHT80

Channel Width Capability: VHT 40MHz

How should I read this? Is the client using 40 or 80 MHz channel width?

Channel Width: = channel widths used by the AP radio.

Channel Width Capability: = The clients channel width capability.

Is it possible to find clients using certain width? Channel Width Capability isn't available in the client table listings

Not quite the info, but the Client Capability report will give you the PHY of clients connected. So from here you can translated this into supported channel width. Might help

Is there a reason you need to find the info?

I'll try that. I'd like to find if any of the clients are using 80MHz as it seems it was left on by default and we'd like to switch to 40MHz width to have more channels.

Wonder if it causes clients to disconnect if we disable 80MHz width during day time?

I've never had any issues with changing the channel width. That being said, within the User Guide certain AP models (200 Series, AP-205H, 210 Series, 220 Series, 270 Series and 320 Series access points) will trigger a radio restart if the 40/80 channels are modified under the High-throughput SSID Profile.

Play it safe and do it out of hours
