RTL8169 not Gigabit in Ubuntu 8.10 Intrepid Ibex
If you couldn’t tell from the title, this one’s a bit nerdy.
I was (as I always am) working on the media server tonight and noticed I wasn’t getting the speeds I used to when transferring data locally. I was maxing out at around 4-5MB/sec (indicating 100Mbit speeds). The router and ethernet card in the Ubuntu machine are both Gigabit capable, and worked in Hardy Heron (Ubuntu 8.04). After some googling, I stumbled on to this thread which showcased how to disable the RTL8169 driver in 8.10 (since it’s apparently causing headaches to people others than just myself).
sudo nano /etc/modprobe.d/blacklist-network
Press enter after the above command is entered into the Terminal. Now paste the following:
# Prevent r8169.ko from loading and allow r1000.ko to load
blacklist r8169
Now save the file by pressing Control + O then Enter. You can now exit the document by pressing Control + X
Now reboot Ubuntu (or restart the networking interface if you know how) and you should see 1000Mbits listed when you right click the network icon in the task bar and get info about your connections!
