I have a very similar problem, which I believe may be related. I have the RTL8111/8168/8411. Since I upgraded to 13.10 I'm noticing a drop in network speed. Installing the Realtek driver didn't help, nor other helpfull tips as disabling IPv6. When testing raw network speed from my Ubuntu to my file server I see speeds between 1,1 and 1,5Mb/s.

(als on the same cable). I haven't tested a rollback to 12.04 to check the actual networkspeed with the old version, or tried a clean install. I may do this to check if all other sources for this issue can be excluded. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1275161 Title: Realtek driver r8169 slow network speed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1275161/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
