I see a several posts about slow wifi and they haven't been answered. My laptop HP Elitebook 745 is currently using Ubuntu 20.04 and its Linux kernel is 5.8.0-38-generic. My other laptop with Windows and phone is showing speed of average 100Mps for download while this laptop is 7Mbps download.
as for lshw -c Network

wifi.powersave = 2
I'm still not having any luck increasing my speed. Any suggestions will be much appreciated. Thanks.

Please see: Installing Broadcom Wireless Drivers
You almost certainly have the wrong driver. I suggest that you do:
sudo apt update sudo apt install -y bcmwl-kernel-source sudo modprobe -r b43 sudo modprobe wl Any improvement?
