Wi-Fi is working slow

Hi, i installed Manjaro yesterday and i have problem:on WIN10 bluetooth doesnt work, wi-fi work properly, and when i installed manjaro bluetooth start working, but my wi-fi started working terribly, i sitting near router and level of my signal is ~50%

I hope I have provided complete information.

Hello @Lost_Soul and welcome :wink:

Not a solution, but a remark:

wifi and bluetooth share the same frequency base band. To coexist both must reduce their signal strength. So it is not a surprise that the wifi signal is now reduced. That is a common practice. Due qca9377 has BT5, it is much stronger and therefore can produce problems with other protocols on the same frequency base band at 2.4Ghz.

IRL it is a bad practice to use bluetooth and wifi on the same chip. You just will not have 100% performance when having both active.

I tryed disable bluetooth now, but nothing changes, thanks for try to give me help
