ON my MSI GT80 SLI, I dual boot 20H2 and the previous version which is 1909.
The 20H2 constantly drops the connection. When I boot into 1909, I have no issues.
I tried everything in this thread:
To compound the mystery, I have a second GT80 identically configured with 1535 and 20H2 and it does not drop the connection.

I am assuming that the drivers are identical in the two 2H20 laptops, and that they behave differently at the same location in your house. I would next check to be sure that all of the adapter settings (including :advanced" ones, especially roaming aggressiveness, are identical. Then I would have a look at the wifi environment (use INSSIDer or similar) to see what other wifi signals are in the environment. Ideally,you would want both bands to be separated from any other signals. Note - if you are using a router from your ISP, many are now configured to use same ID and password for 2.4 and 5.0 GHz signals, so they will switch to 2.4 if you are in an area where the 5.0 is not so strong. Sometimes this signal switching will cause drops. You can use different IDs and passwords to prevent this switching from happening, if it is causing problems.
Good luck - troubleshooting wifi can be a pain.
Best,

The Killer 1535/1435 are based on the Qualcomm QCA6174A, the 1535 having better amplifiers while the 1435 is a stock 6174A. @Tech Junky you are confusing the AX1650 and AC1550 which are rebrands of the AX200 and 9260AC respectively.
Search Windows catalog using QCA61x4A as the search term and order by date, you should be able to get newer drivers from there, test those and let us know if it helps.

There is no fix for killer 1535. The only fix is to replace it with an intel brand m.2 wifi card.
I did that on one of my machines and it's working enormously better. No more drops. Speed is about the same.

Every killer card I’ve ever had has been junk. I’ve always replaced with a high end intel card and never had problems after that. Killer 1202, 1103, 1535 have all been junk.
Killer 1535 constantly drops connection
