Config bandwidth

When I configure the htmode parameter to be HE160, it means the bandwidth will be 160MHz. In this case, if in a noisy environment, can the bandwidth be reduced to 20, 40, 80 MHz to avoid interference or not?

In a noisy environment, it is better to reduce the bandwidth to avoid interference. You should run a site survey and check what is the channel utilization in the areas that the AP is covering.

Of course, as you mentioned, that's manual configuration, but I'm referring to the automatic scenario. If manually configured, then the environment becomes noisy, the service may halt.

Only if acs finds all other half-bands busy. Not possible with fixed channel selectection.

  • The client will automatically adjust its TX bandwidth as necessary
  • The AP will do the same (per client)
