Unfortunately I had similar issue when rt-ax88u came to my house and I have to update wifi drivers on all laptops and pc in my house. One thing you can try is to create guest network for 2.4Ghz and see if that will work.
Also look under Advanced Settings > Wireless > General is an option for ‘Wireless Mode’ Select N for 2.4 GHz or 5 GHz and create new SSID just for that legacy laptop.
I think as @Mrk26 said, Guest option with Wireless Mode set to N should work if that option is available via guest wifi, but I think guest wifi does not allow access to local printers etc, only internet access.
In a completely sane world, madness is the only freedom (J.G.Ballard).
I have connected several different devices and no issues at all, nice and stable like previous official build.
I used Merlin fw on mine a while ago and once switched to previous official fw didn’t have a chance to messing around. Can’t really afford any possibly unstable builds especially where I still working from home so stable broadband connection is a key.
