Interesting issue.
I updated my Flint2 to the 4.7 Beta firmware a couple of weeks ago. All running well on majority of devices.
However, 1 x HP Elitebook does not play nice with this router following the upgrade.
All other devices getting around 460Mbps on speedtest.net with a ping of 12ms.
This HP laptop (Qualcomm wifi 6 card) get 54Mbps with high latency of 102ms.
Connecting the laptop to the old Asus router, I had no speed issues.
So I set up the old router as an Access Point. When I connect to it, the HP Elitebook gets the same speed as the other clients on the GL.Inet router.
Is there a known issue on 5GHz with Qualcomm cards (Linux Mint 22, 6.8 kernel)? Asking here since the wifi works fine with other routers / access points.
