On a recently flashed PBP with Manjaro KDE Plasma 20.04 (flashed from SD to EMMC installer), my WiFi worked great, 5G gave 150+Mbps download (on par with my other devices). Then, I did the 300+ package upgrades that Package Manager suggested. Immediately after the successful upgrades, my 5GHz WiFi download speed dropped to 30Mbps. Now, 2.4GHz WiFi is faster (about 40Mbps), which is unusual to the wireless settings I have at home. I reflashed the PBP to confirm. It happened again. Wondered if anyone else encountered the same slower WiFi issue. 40Mbps is not bad, but it bugs me that the PBP can't function as expected. Many thanks in advance for any idea how to up the 5GHz WiFi speed back to normal.
