WiFi performance is slow

[Jonas Gamao]

I'm on a 5GHz WiFi network, and my download speeds are slow (roughly 1Mb/s). Tested it with 2.4Ghz connection. For some reason, my upload speeds are fine.

I tested on my other phones, and they aren't experiencing issues (roughly 100Mb/s download). My old laptop, which uses a Broadcom WiFi and only capable of connecting to 2.4GHz, has faster download speeds (roughly 20Mbps). It's also on Focal.

Forgot to mention that it also happens at fresh boot.

It seems that removing that package will improve its performance

Odd...

Status changed to 'Confirmed' because the bug affects multiple users.

I faced poor performance as well with this package. The weird thing is my WiFi card work as expected but additional drivers shows that the device is not working as suggests to install this package. The only way to do it is via apt since you cannot do it from the gui for some reason. But after install the performance is really poor.

Same problem here.
Removing the package solves the problem

Performance improved after removing this package. +1
