    13.10 RTL8111/8168/8411 slow internet

    I am trying out 13.10 Xubuntu running kernel 3.13 on an external hard drive and it appears like my browsing speed is really slow and I don't know whether to attribute it to the fact the installation is running from a usb 2.0 hard drive OR if it's the rt8169 driver built into Xubuntu 13.10. Is there any tests I can run or whatever to figure out what's causing the slow down? I'm running namebench to check and make sure i'm using the fastest dns servers and I am also going to try out google chrome stable 64bit because firefox just seems slow!

    Re: 13.10 RTL8111/8168/8411 slow internet

    wow, no one else has this chipset with ubuntu 13.10? it's on my Z87 motherboard and I would think people are experiencing this as well. Maybe it only affects 64bit and or xubuntu? I can't even install steam from Ubuntu software center, i click buy, then it brings up the terms of use which spins and spins forever and then it returns "could not resolve blah blah". I have to click decline just to try again only for it to fail again. I think it finally worked on the 4th try.

    very interesting syslog output

    so currently my only active eth is eth2 for whatever reason. the module r18169 provided by default in ubuntu 13.10 is not working properly with this chipset.

    Re: 13.10 RTL8111/8168/8411 slow internet

    May we see the outputs of -
    Code:
    sudo lshw -numeric -C network
    ifconfig -a
    sudo ethtool eth0
    sudo ethtool eth2
    And have you considered trying the proprietary (r8168) driver yet? Assuming it supports your card.

    Apart from installing with apt-get, is the speed and connectivity otherwise good? For example, if you start downloading Ubuntu ISO via torrent, does the connectivity/speed remain good? If yes, I would suspect the problem to be DNS related. Maybe try changing to OpenDNS or the google ones (8.8.8.8, 8.8.4.4).

    The outputs look solid and there are no packet drops or frame errors either.

    Re: 13.10 RTL8111/8168/8411 slow internet

    but you can see it has an issue staying UP. via syslog you can clearly see it says link down, link up, link down, link up, link down, link up. That right there is not a DNS issue, thats the browser having trouble because the NIC is going up and down.

    My entire network already uses the google dns servers and my other machines (windows) don't have any issue surfing the web

    Re: 13.10 RTL8111/8168/8411 slow internet

    had to perform a fresh install due to a stupid error by my own hand. Anyway, before I install and use the realtek r8168 driver i thought i'd give the default kernel module another shot. (r8169) I am still getting very weird issues with the NIC. For example I couldn't even install a game from steam, i got the following message:



    Here's the same info but using the r8169 driver

    Yes, I ignored those ups/downs earlier, thought it might have been during a physical plug/unplug attempts. If it's happening by itself, the connection is clearly being reset either due to a bad physical connection problem, or due to the driver not being able to keep up with the Gigabit speeds (or due to something I couldn't think of).

    Even if the same connection is working fine in Windows session on the same machine (if it is dualbooting), I'd recommend trying a different, tested good cable just to rule out the physical connection problem.

    Assuming the problem remains the same even after the cable change, may we try a forced lower speed? A 100 Mb/s FD would be much better than practically nothing -
    Code:
    sudo ethtool -s eth2 speed 100 duplex full autoneg off
    If this doesn't help, then to reset above to current defaults -
    Code:
    sudo ethtool -s eth2 speed 1000 duplex full  autoneg on
    (although I think only "-s eth2 autoneg on" is sufficient, but to be extra safe)

    Re: 13.10 RTL8111/8168/8411 slow internet

    i have solved it but it did take a lot of googling and reading. i am still using the included r8169 module that came with Ubuntu 13.10 BUT I did disable ipv6 AND I commented out "dns=dnsmasq" within /etc/NetworkManager/NetworkManager.conf. then i restarted my machine and then instead of 127.0.1.1 showing up as my dns server (no idea why that would be a dns server), now the router's ip address was being used which is the way it should be. I did also remove "wins" from the nsswitch.conf file, the line that reads hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
