I have tried 2 separate HP Laptops, one with AC8260 and one with AC8265 cards,
and both have issues sustaining a solid connection to my RT-AC1900P (RT-AC68U)
Asus router on the 2.4Ghz band. The connection will randomly lose pings to the router
for about 20 seconds then fix itself, however the wireless link remains connected.
Laptops are Spectre x360 (one Pro - older model) and one newest Intel 8th Gen.
This is on both laptops running latest drivers 20.40.0.4 (also tried many older ones),
and Windows 10 Pro x64 (latest updates). The wireless network has a strong connection
and it's always full bars and 144/144 Mbps (this is running on a 20 Mhz channel width),
although I've tried many other options, including changing power options in the Intel
Wireless drivers as recommended on Intel Technical Bulletins, without success.
New installs of Windows 10, as well as factory resets, tried everything ...
Sometimes the issues happens every minute, sometimes every ~10 minutes.
The same cards seem to work fine with an Asus RT-N66U on 2.4Ghz band.
What's the next step for troubleshooting this issue ?
Thanks in advance!
