I got same problem on ux31e and ubuntu 12.04 & kernel 3.2.0-22. On syslog i found a lot of logs about Bad Header Length... asix 2-1:1.0: eth0: asix_rx_fixup() Bad Header Length asix 2-1:1.0: eth0: asix_rx_fixup() Bad RX Length 1716
So, when i copy a big file (size ~ 3,7 Gb ) from home network with 100MBps of capacity, my ux31e only transfers 300kB/s. I checked the network hardware with "sudo lshw -c network" and its says that support 100Mbits. ** Attachment added: "syslog-to-report.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/947723/+attachment/3153597/+files/syslog-to-report.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/947723 Title: ASIX USB-Ethernet driver noticably slow, dropping packets and reporting RX errors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/947723/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
