Having wifi issue

Hi Manjaro Team,
I am using Manjaro Linux, and whenever I connect to the 5GHz WiFi, the speed decreases. I mean when i connected it with 5g network it is not getting the actual speed. The speed is fine when connecting to the 2.4GHz WiFi. In the case of Ubuntu, it works well.
kindly help

Hello @Nobita and welcome :wink:

I am not part of the Manjaro Team, but maybe I can help you.

First we need your system information. Here is a tutorial how to do it right:

i have given , thanks for giving me the tutorial for system information.
how can i fix that wifi problem. pls help

Without knowing which module/driver and/or chipset is being used, no one can help as it would be a guess on assumptions.

EDIT: Alright you added the inxi. Iโ€™ll take a look.

i have given now inxi@megavolt
please help

@Nobita Questions:

  1. Is Bluetooth enabled when you use WiFi? In reality that can reduce latency and therefore speed, more over on chipset which has both on one chip.
  2. Can you test the signal strength? wavemon is a great terminal tool for that purpose.
pamac install wavemon

then run:

wavemon

So test it with 2.4Ghz/5Ghz with and without Bluetooth enabled.

Sorry, there is no general solution, so we need to troubleshoot it and get the correct conditions when it happens.

This a topic seems to be related: Realtek 8852BE Bluetooth and Wifi But the OP sees the problem when bluetooth is enabled.

but in other distro like garuda or ubuntu
it works fine even bluetooth is on.
when it comes to manjaro itโ€™s speed goes slow.

Well, then switch to Manjaro unstable branch, which is actually ArchLinux stable and what Garuda uses. Also use the most current stable kernel. See if that works for you then.
