AC-3165 Network Adapter Transmit Rate low (86.7)

I've been experiencing issues with my internet speed over the past few days - I recently updated my drivers through the Intel Support Assistant.

 

I have gigabit internet, but speed tests are showing ~50mbs (my ISP is showing 1.13 gbs at source).

 

My network adapter is showing a transit and receive rate at 86.7 Mbps. Given the theoretical maximum of 433 Mbps, I'm wondering if there's something I've done (or that the update has done) to slow my adapter down.

 

I've attached the result of the System Support Utility for my network.

 

Thanks in advance for any help!

 

In case it's helpful, the output of netsh wlan show interface in admin mode

 

There is 1 interface on the system:

  State         : connected

I adjusted the properties of the adapter, switching the channel width for 2.4 ghz to 20 and, for some reason, I'm back to 433 and the connection is good :)

I have the same issue with the same speed and I am not able to solve it the way TSomm2 solved it. I have 86.7 mbit speed, just like TSomm2.

Never mind. I fixed the issue by installing an older driver, 17.15.0.5. Now I have 433 mbit again. Apparently the latest driver is not working very well, which is 21.90.3.
