Even following all the recommendations, the problem still hasn't been resolved. I have an Archer T3U that works very well and doesn't have these ping spikes, but on the Archer Tx20U Plus, these spikes happen at least once an hour.

I updated my TX20U Plus to this latest driver.
But the Advanced Settings does not show all of the items shown in your post.
How do I get to display all of the settings?

Hi, welcome to the community.
What is the operating system of your Windows PC?
Without the extra modification of the advanced settings, would the beta driver help with the network stability?
Wait for your reply.
Best regards.

Using Windows 10 64 bit
Not sure I would need to use the other Advanced settings
Just curious why they are not showing up and how to get them to appear
I have been having problems with the TX20u periodically disconnecting on 5ghz even though router and signal strength are not the problem
I have other devices on 5ghz that do not disconnect even though their signal strength is less.
I can't say for sure whether the beta driver helps in this regard.
Anecdotally, it seems that the disconnects are much less frequent

First of a all nice to see that this issue is taken serious!
A handy site fory everyone who wants to check to see how stable ping is
search in google for: packetstats and click probably 1st link
I checked it with this version: 5001.19.113.4 which shows a lot more stable ping:
I also tested with
5002.19.128.0_Beta and that one does NOT improve it.
My setup is: TP-link deco m5 and X50
with other versions i see spikes >300ms within 5 minutes.
To other users i would say - use "packetstats" and let it run for 5 - 10 mins with old driver and then use 5001.19.113.4 to see if it improves

Hi, may I know how long you have had the Archer TX20u Plus?
Were you able to constantly reproduce the issue of random ping spikes?
If you'd like to spend a little more time, you can start a ticket to The Local Technical Support with the following details:
- The driver and system info of the computer.
How to check driver version of TP-Link adapters and system information of your computer
- The model number of the home router.
Thank you very much.
Best regards.
