Not sure how to check signal's dbm on windows...
But the signal show i'm getting 4bars? and ~70% signal strength in cmd.
You're in the right place. Signal strength ~70% is just ok. 80 and above is best.

And I don't think the router is hot enough (at least to my touch)

Tested just now...
Tried putting the wifi near to the router..
Seems like i'm getting 100% speed and uptime on the short test i've performed.


Getting back to the room, only managed to get a few times of non-disconnection.
But most of the time, same thing...

So, i'm suspecting the usb wifi can't really connect to the 5ghz properly.
What probably solution should I take?
Should I get a repeater/extender?
Change a new router (with stronger signal)?
Or buy a cheap router and make it as a bridge?

Remove the wall between the router and device by moving the router instead. laugh.gif
5Ghz signal typically drops off after 2-3 walls in between. Try moving the router higher up (bookshelf top/cabinet top).

Also device quality (not router quality) can have an effect.. if the USB wifi being blocked by a metal casing of desktop PC..
to have the best signal quality even using the most cheapo router in the world = "clear line of sight" without metal, walls, other solid objects
may want to move or extend the USB wifi with a USB cable for better LOS placement

For easier GUI interface on windows can use Xirrus Wifi inspector https://xirrus-wi-fi-inspector.en.softonic.com/

The usb wifi are connected to a hub ~50cm aparts from the PC itself.
The router are stuck to the wall, above head height.

Getting clear line of sight, is a bit impossible at this point.
And using extension cable, will be messy.

Yes... but currently it only affect the USB wifi on the PC only as the other devices, can connect to the 5ghz without any problem.
So, suspect it is whether the USB wifi it self is weak... or something's wrong with my Windows.
Haven't tried yet with other pc/laptop available
