I'm trying to figure out the best driver/settings for this adapter. Connection keeps feezing, meaning that it goes full speed - then stops for 2-3 seconds - and comes back at a full speed. Really annoying. Also once on idle for a longer time, it still likes to turn off the wifi (I do have that box unchecked in Power management tab).

 

I tried three different drivers:

 

1. Win10 automatic installed one (seems to be with the latest date)

2. T4U V2 from TPlink Support page

3. Generic Realtek drivers v. 1030.25.0701.2017 for the chipset.

 

I had the worst results with Win10 drivers and little bit more stabiloity with other 2 options but it is still a lot to desire.

 

Based on some tweaks I was able to find online, I went ahead to advanced settings tab of the adapter in Device Manager and that's what I put it into:

 

AdaptivityPara = "0"

BeamCap = "BEAM Disable"

EnableAdaptivity = "Enable"

High Adhoc Mode = "Disable"

HLDiffForAdaptivity = "7"

L2HForAdaptivity = "F5"

LdpcCap = "VHT LDPC TX|RX"

Preferred Band = "3. 5G first"

QoS Support = "Support QoS"

StbcCap = "VHT STBC TX|RX"

USB SF Mode = "Disable"

USB Switch Mode = "Auto"

VHT 2.4G = "Disable"

VHT 2.4G IOT = "Disable"

Wifi Config = "Performance"

Wireless Mode = "IEEE 802.11ac"

 

It still drops connection for few seconds here and there, I'm running out of ideas and starting to think that this device/chipset is just faulty.
