    Slow Download and Upload Speeds



    Recently, I was having some terrible download and upload speeds. AT&T came out and gave me a new router and every device in my house from phones, tablets, and my Windows based PC's are now getting close to the 12 Mbps Download Speed and 1.5 Mbps Upload Speed via our Uverse. Undoubtedly, I have tried everything up until this point to figure out why I am getting such slow speeds on my Ubuntu machine.

    Here is some helpful information.

    Code:
    name@box:~$ sudo lshw -C Network
    [sudo] password for name:

    I was hoping someone could shed some light on this issue. Downloading things, especially through the software center, takes a very long time. Apt-get seems to work alright, but still should be substantially faster than what I am getting. Lastly, here are the system specs:
    Code:
    name@box:~$ uname -a

    AMD FX-4170 Quad Core (4.2 ghz)
    8 gb Patriot Memory (2 x 4)

    GeForce GT 620 (Dual DVI, Mini hdmi)
    1 TB Seagate Hard Drive (7200)
    Asus Wireless-N 300 Mbps PCI
    Any help would be appreciated, thanks.

    You use wifi? If so, what if you use fixed ethernet?

    Please answer what sanderj asked above. If it is wireless, please follow the "Wireless Script" link in my signature and post back the result as mentioned in the linked post.

    Undoutedly I do not have the ability to connect via ethernet. Here is the output from the script you provided.

    Re: Slow Download and Upload Speeds

    First and foremost, please change the encryption in the router to pure WPA2-PSK only, choosing AES instead of TKIP. Currently it is WPA/WPA2 mixed mode.

    If that does not help, try -
    Code:
    sudo modprobe -rfv rtl8192ce
    sudo modprobe -v rtl8192ce swenc=1
    This will be a temporary change and will be lost on reboot. If it seems to help, we can make it permanent.

    If none of these help, we may have to compile the proprietary driver like mentioned here : http://ubuntuforums.org/showthread.p...8#post12700188

    But the encryption in the router should NOT be WPA/WPA2 mixed mode in any case. Do change it first as suggested above and leave it that way.

    Re: Slow Download and Upload Speeds

    Made the change to WPA2-PSK via AES. That was undoubtedly just the default, so I never messed with it. Retested my speed, no change.

    Though, the changes made via the command line appear to have worked. I appreciate the helpful and timely response.

    I'm assuming to make it permanent I could write a shell script and set it to default at boot? Or do you have another suggestion? Thanks!

    Actually there is a recommended easier way to make it permanent. In a terminal, just do -
    Code:
    echo "options rtl8192ce swenc=1" | sudo tee /etc/modprobe.d/rtl8192ce.conf
    This will create a configuration file "rtl8192ce.conf" in the /etc/modprobe.d directory with the given setting for the driver. The name doesn't matter as long as its extension name is .conf.

    Keep it on test bed for some time (or a couple of days if you wish) and let us know if the improvement is real or just coincidental.

    If it seems to be a definite solution, please consider marking the thread as [SOLVED].

    Re: Slow Download and Upload Speeds

    Thanks for the help varunendra. Undoubtedly, I spoke too soon. I was getting the speeds that I needed but now, undoubtedly, am back down to where it was. I made the change via the command above as well.

    Did you try installing the proprietary driver then? Like mentioned here : http://ubuntuforums.org/showthread.p...8#post12700188

    I downloaded the most recent driver from here: http://www.service.asus.com/#!downloads/c1wax

    I extracted to the desktop and tried to run make. Got an error.

    Code:
    uname@comp:~/Desktop/Linux$ make
    make -C /lib/modules/3.5.0-36-generic/build M=/home/uname/Desktop/Linux modules
    make[1]: Entering directory `/usr/src/linux-headers-3.5.0-36-generic'
