Data Rates of clients connected via MR36's

All our clients connected to the MR36's show a low Data Rate as % of client max:

The above is for one client I selected at random.  I have never seen any above 50%

 

In Wireless>Access Control, I have the following settings:

All the clients are Windows 10.

 

Is this normal?  I am curious as to why this is not closer to 100% of the client max.

 

Thanks in advance

Steve

Let me make up some numbers to illustrate the point.

 

Lets say a client has 100MB of data to send.  There is a fixed amount of RF airtime.  If they send that data at 11Mb/s it will take twice as much airtime as sending it at 22Mb/s. The airtime can only be used by one client at a time.  So by consuming such a large chunk of airtime, it leaves a lot less for everyone else to use, causing their throughput to be much lower, even though they might have a high connection speed.

 

Even one single client with a low-speed connection transferring data hurts the performance of every other client.  Worse still - they don't even have to be on your WiFi network.  They could be on your neighbours.

 

So typically you don't want to allow low-speed clients.  A minimum bit rate of 12Mb/s is pretty standard these days.

Change the minimum data rate to 12Mb/s.  This disables all the slow legacy protocols.

Thanks for the reply Philip.

I will change that as soon as I get the chance.

Would that then allow the clients to operate at Data Rates >50% of the client max?

I'm interested to understand how changing the minimum support would cause the others to run at a higher rate?
