The wireless connection signal on Windows is really strong, while on Ubuntu it oscillates. I've tried all the options available here: https://itsfoss.com/speed-up-slow-wifi-connection-ubuntu/ and none of them worked. Whenever I test the wifi velocity it gives the same as Windows, but on Ubuntu it sometimes completely falls. It only happens on my router a TP-LINK Archer 7.
Is there a router setting to solve this?
