Ever since moving to Pop!_OS 22.04 LTS wired networking have been very slow. I recalled seeing posts on this problem and the issue being the included driver for the RTL8111\/8168\/8411 PCI Express Gigabit Ethernet Controller.<\/p>\n\n\n\n

Performance was not only poor but downloads were much slower than uploads as evidenced by the Speedtest CLI package:<\/p>\n\n\n\n

Download:
* Speed: 83.19 Mbps
* Jitter: 34.18ms, low: 6.21ms, high: 385.14ms
Upload:
* Speed: 464.66 Mbps
* Jitter: 58.86ms, low: 8.41ms, high: 1139.23ms<\/p>\n\n\n\n

The problem is the driver is the r8169. The solution is replace the r8169 with the correct r8168.<\/p>\n\n\n\n

Here are the steps (thanks to \u00a0realtechtalk.com – full details at: https:\/\/realtechtalk.com\/Ubuntu_Debian_Linux_Mint_r8169_r8168_Network_Driver_Problem_and_Solution-2253-articles<\/a>)<\/p>\n\n\n\n

    \n
  1. Download the r8168 driver:
    sudo apt-get install r8168-dkms<\/code><\/li>\n\n\n\n
  2. Make sure the r8169 module doesn’t load any more:
    sudo echo \"blacklist r8169\" > \/etc\/modprobe.d\/blacklist-r8169.conf<\/code><\/li>\n\n\n\n
  3. Remove the current r8169 driver:
    sudo rmmod r8169<\/code><\/li>\n\n\n\n
  4. Install the r8168 driver:
    sudo modprobe r8168<\/code><\/li>\n\n\n\n
  5. Activate the change:
    sudo systemctl restart networking<\/code><\/li>\n<\/ol>\n\n\n\n

    Here are the new results (noting people in the house gaming, streaming, etc.):<\/p>\n\n\n\n
