Orbi RBS850 (with satellite) keeps disconnecting Wi-Fi Computers

Hello folks, I'm having persisting problems of my orbi wifi disconnecting my laptops. I know it's only laptops since our phones are fine, and I say it's the orbi wifi because my wi-fi connection in school and everywhere else is fine too. I've searched this community, and tried a few of them, but I really can't figure it out. My PC is connected to the satellite (more than 30ft away from the router) and has no issues also. While typing this, I had to reconnect for around 3 minutes or so. The only way to have stable connection is to connect thru ethernet cable.

Below are my current settings and would like to ask for suggestions as to how to solve this persisting problem.

Current laptops, Thinkpads T490 (AC Wifi) and P17 (AX Wifi)

Orbi Firmware Version
V4.6.9.11_2.3.5

Orbi network settings:

Tried playing with the 5 GHz channels, still the same.

It is on router mode, from ATT Modem

I just enabled the IPv6 since my provider also provides it. Still issue persists.

No VLAN/Bridge, static routes, VPN service, Dynamic DNS, Web Service management was set up. 

Thank you in advance for your input! Hopefully this can be resolved.
