RT-AX86U 386.4 slow speed

[johndoe85]

I have 500/500 and dont get near maximum speed, so i took the bull by the horns and reinstalled the merlin firmware 386.4.
Directly after reinstall and entering password and such, i do a speedtest and i get this result https://www.speedtest.net/my-result/d/e39834cb-ceb2-4b26-8cba-113536a2309c
but if i do no changes at all and just reboot the router, i get this result https://www.speedtest.net/my-result/d/1ff24dbc-bda0-414d-b143-8f8ec7954e0f

And i wonder what has changed?

I have reinstalled the firmware twice with the same result.

I use the restore button with the box ticked for "Initialize all the settings, and clear all the data log for AiProtection, Traffic Analyzer, and Web History."

I am using ASUS PCE-AX58BT AX3000 with the latest drivers for these tests.

EDIT: I posted this too soon, apparantly i was at 2.4ghz after reboot.
failsearch will continue and i find nothing after making changes and rebooting i will update this thread. Respectivly i will update this thread when i find a change where there is actual speedloss after reboot and being on the actual 5ghz

As the title says I am experiencing slowness with Asus PCE-AX58BT using the RT-AX86U router, with AX58BT I am having figures of 150 MBps download and 600Mbps upload and with a oneplus 7 pro (launched in 2019) 500 mbps download. Can anyone shed some ideas on why this is happening?

Don't necropost, especially since this thread was about a specific firmware version that's two years old, and which you probably aren't running either.
