AP tx limit, client tx limit in wireless registration table

Hi, some my clients have bad signal and when there is the worsening of weather, they cause other clients connected to the same card big raise in ping. I want them not to connect if they have bad ccq, or throughoutput. I found in wireless registration table ap tx limit and client tx limit - can be that used, what does it mean and what does it do? Can you help? Thanks

hello, you can select signal strength range in ap access list , if you want to disconnect wireless connection of that client remove both ticks of authontication and forwarding

I know that, but I dont know what mean ap tx and client tx limit, under circle you made.

AP tx Limit and Client tx Limit == datarates ( bandwidth for Client )

What values are accepted here? Is it the best way to limit the bandwidth used by each radio?
