Resolve slow connexion when using wifi in ubuntu 13.04 Raring Ringtail, 12.04 and LinuxMint13

Written by M. Zinoune on . Posted in Linux Mint, Linux tutorials, Ubuntu

Updated-30/04/2013: If  after installing or upgrading to Ubuntu 13.04 Raring Ringtail. or to Ubuntu 12.04 LTS Precise Pangoline,  if you noticed a slow connexion when using the wifi, this is a simple solution. This solution works also for LinuxMint13 and above.

1- First MethodA second The first solution for the slow connexion issue can be by using the following :

Open terminal and enter the following command:

.

.

sudo -s gksu gedit /etc/modprobe.d/ath9k.conf

at the end of the file add this:

options ath9k nohwcrypt=1

Save an restart your OS.

If you still have the issue of slow connexion, then try instructions on step 2.

2- Second Method:

This method involves forcing iwlagn to not use n, the commands will disable n on the device without making it a permanant change, check first if this work for you, if you notice that the speed improved then continue to make the change permanant. If this solution didn`t work for you, then reboot your computer to revert the chnages.

sudo rmmod -f iwlagn
sudo modprobe iwlagn 11n_disable=1

If you notice that the wifi speed improved, then make the change permanent :

gksudo gedit /etc/modprobe.d/iwlagn-disable11n.conf

and add this line to the file:

options iwlagn 11n_disable=1

save & quit

3- Third method to resolve the slow connexion issue: You need to disactivate IPv6, to do that, open terminal and enter the following commands:

echo "#disable ipv6" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf

Then restart your system.

Please report if the solution discribed in this post worked for you by commenting this post. Thanks for your help.

    YES!
    thank you so much. I’ve been searching old threads and finding nothing to help my slow smb speeds.
    …Just for the record this works splendidly for Mint 11. the above line is the only string in the newly created ‘ath9k.conf’ file.

    beauty.

  • Alberto

    I tried method 2 on Mint 11 and it worked like a dream.

    Thanks guru. This is why Linux for the desktop and for the common user is Free Crap.

    "If after installing or upgrading to Ubuntu 11.04 you noticed that the connexion is too slow when using the wifi, [there] is a simple solution."

    Switch to openSUSE? :-)

    Seriously, disabling things that could be necessary very soon like ipv6 isn’t really a solution. A solution would be a Ubuntu-side update to fix whatever’s causing the problem.

  • http://xjonquilx.co.cc Jonquil

    Confirmed working on an MSI U100 using most up to date version of Ubuntu 11.04

  • http://xjonquilx.co.cc Jonquil

    Why is it people like you always come out when Ubuntu is the middle of a developmental release? It’s quite easy enough to re-enable IPv6 once an update is available for this bug, which I’m sure will be soon as an LTS version is coming up. You act like you show no patience when your own choice of distro comes up with a bug when obviously you wait like everyone else for the bug to be fixed, other wise you would not be using it at all.

    • Joseph

      11.04 isn’t an alpha release, it’s a release. Making a release with serious bugs that should have been caught in testing isn’t good for Linux and the solution isn’t to just pretend it didn’t happen. Ubuntu 11.04 has garnered many negative reviews this release from major Linux sites suggesting people stick with 10.04, which doesn’t help Ubuntu either. I mentioned openSUSE in my original post, but it’s a good example. People weren’t happy about some things and the development cycle was then changed to 8 months from 6 months. Now it’s praised as being very well polished. This happened because people spoke up and insisted on it. Several users of Sabayon Linux (including myself at the time) expressed displeasure when rolling updates broke the system and made our desires very clear for a more stable repository to allow easy reverting to a previous version if something broke. The head developer listened and created such a repository after enough people spoke up, even though one of the other developers initially dismissed the idea as "impossible" after the first person suggested it.

      If Ubuntu users just "wait patiently", the message will be sent that users don’t mind when releases come out with issues like this or that they prefer more work be spent during a release cycle on novel new features like Unity rather than stability and bug testing and the distribution will start to become more like Fedora. If people were really inconvenienced by this they do need to say so so developers know what the priority of their users truly is.

  • Toza

    Sadly, this tip had no effect on my machine. Average speed is still 4-5x slower then when I use Mandriva. Somebody mentioned SuSe, maybe that too is a good alternative.

  • FFV

    It totally worked for me!
    Thanks a lot!!!

    Hi,

    Re: second method
    Here’s a copy of everything entered into and returned by the terminal after I submit the command gksu gedit /etc/modprobe.d/ath9k.conf

    [sudo] password for ubuntu:

    • mizo

      Hi K;

      you have issue with the Gedit, try with vi /etc/…. or nano /etc/….

      it will works sure

  • JOHN

    Method #2 worked for me on Natty 11.04 with an Acer Aspire7741G

    * As a side note, I previously tried disabling power management by Natty on the wlan which did not work.

  • Mithun Daa

    Step 1 did the trick for me. Thank you very much.

  • http://enteryoursiteURL... Eric

    Thanks so much! My wifi connection is now as fast as it is on my windows machine.

  • Derek

    Performed fix 1 and had no success. I tried method 2 but got this feedback.

      See answer from Mizo above :

      Use another edtor and surely will work for you

    • mintNewbie

      I had same message. All I did was create the file and add

      options ath9k nohwcrypt=1

      to the file.

  • MartiL

    YES! Finally, a normal WiFi connection! Thank you so much for posting, solution 1 works like a dream!

  • MartiL

    Darn, it didn’t fix it. Just seemed that way, but it’s up and down again :(
    Solution 2 didn’t help much as the code was already in the file.

    So, we’re back to wired internet … (am I the only one who soooo regrets updating to Natty?)

  • mintNewbie

    After upgrade to mint11, my wireless connection speed went down to dial up modem speed.

    I couldn’t take that slow connection speed. Fortunately, your information 2nd method helped to get my wireless speed back to normal.

    Thank so much.

    It looks like every odd number version of mint come some sort of annoying bugs..

    but same time, good people have helped to solve problem. :)

  • Netburn

    Thank You!

    So far it seems second option did it for me. I’m so glad this worked, this issue was driving me crazy.

    Regards.

  • http://enteryoursiteURL... frodude

    thank you so much method 2 works! I thought i was gonna screw some where since i have very little experience in command prompts like terminal. thanks again!

  • alejandra

    first method seemed to solve the issue for me, thanks a lot

  • http://enteryoursiteURL... islandboy

    I can’t detect wireless at all after I install Ubuntu 11.04

  • D Bruce

    Just a heads up that this worked well for me. I opted to leave IPv6 working as it’s being rolled out across the web now, however the second config edit nearly doubled my speed. Not quite where it was with Win 7, but manageable now until I can debug later.

    THANKS A BILLION!

    • zinovsky

      You are welcome :)

  • Vitor

    It worked (second method)! Thks very much!

    Hi – THANKS!!!!! I am on Linux Mint 11 on a wireless connection. My speed tests were showing download speed of only 1 to 2 MBS, on a 25 MBS Fios. Win7 PCs were all showing 25MBS. On the tests on Mint, the upload was showing 14 MBS! So I did your method 2, now download is 25 MBS! Fantastic!!!!!! I wonder how many zillions of people are limping along on this problem?

  • Jds

    The first solution fixed the slow wifi on Linux Mint 11
    Thank You!!!

    FYI, Ubuntu 11.10 seems to have a bug in regards to 802.11n. These methods didn’t work for me and I actually had to turn N off at my router. It’s a high priority bug right now…

  • Douby

    1 & 2 didn’t work for me but this di :
    sudo rmmod -f iwlagn
    sudo modprobe iwlagn 11n_disable=1

    bug with n wifi

    make this permanent :
    gksudo gedit /etc/modprobe.d/iwlagn-disable11n.conf

    add
    options iwlagn 11n_disable=1

    save & quit

    • http://enteryoursiteURL... zinovsky

      Thanks Douby, i will test this method in Ubuntu and Linuxmint.

    • Buck Yeh

      Thanks! Works for me in Ubuntu 11.10

    • ejt

      Douby’s method worked like a charm, without having to disable IPv6. I’m using Ubuntu 11.10 on a Lenovo W520. Thanks a lot!

  • room271

    Can someone post how to revert these changes please.

    Not sure if it is important to revert back or not if they didn’t work, but can someone explain how if it is.

    Thanks

  • Anton

    Neither 1 nor 2 worked, but Douby’s solution did! Thanks!

  • Pavan

    solution 1 worked like a charm.. faced the exact same problem…

  • Cory

    Method 2 did the trick for me. Thank you sir. Seems like every new version of ubuntu comes with some major and incredible annoying bug. At least this one was an easy fix.

    • Cory

      using ubuntu 11.10 on an Acer Aspire 5552g

  • Joseph

    So this was NEVER fixed on Ubuntu’s end, even in 11.10?

  • Mapuka Mueller

    non works for acer aspire 6930G…
    video halts after ever 3 seconds and loads for about 10 min for the next packet.
    * Would be ok, if this was an alpha- or beta- but not a full release * How can a system so robust in many other "more" complex domains so SUCK in less complex WIFI ?
    This windows nerds won’t wait to point fingers at me ughhh.

  • mavu

    doesnt work.. any of the method’s deactivate wireless

  • asdasd

    Thanks :D

    Worked for me on 11.04 U :D

  • Mads

    Method 2 worked like a charm on my MSI Wind U120.

    Everything was working fine on 11.04 but after I upgraded to 11.10 the Wifi connection would work for a few seconds and then disconnect, and refuse to work thereafter.

    It seems HW encryotion support shouldn’t be enabled for the Atheros 928x chipset?

  • John

    Yeah! Thanks alot. Soulution 1 worked for me. :=)

  • Ays

    It worked! I was wondering what was happening because I mostly use a wired connection. The first method didn’t work for me, but the second one made it all better.

  • http://www.squidoo.com/download-ubuntu Mediawizard

    Great it works, wifi connection is faster.

    Method 1 — Some improvement in speed

    Then I also tried method 2

    wifi speed looks now fine

    Thanks a lot.

  • PatHibulaire

    I’ve tried the method 2 without disabling IPv6 and it worked as expected.
    I’m sure the issue is not related to IPv6 but to hardware encryption instead…

  • Exasperated

    This problem is an infuriating nightmare in Mint 11! A Release this pathetically buggy is what drives people away from Linux.

    I am completely new trying to get away from Windows.

    I have the same problems as K. And No, I have no idea what else to "edit" with, where to locate it or how to use "edit". I only have what originally came with Mint 11.

    Can someone please post literal step-by-step solution instructions?

    Thanks.

    Hi, I m using MTS Data Card in Ubuntu12.04 and ‘sudo iwconfig’ shows following:

    ppp0  no wireless extensions.
    lo       no wireless extensions.
    eth0   no wireless extensions.

    I tried ur Ist step:- no increase in speed
    IInd step:- Message: “ERROR: Removing ‘iwlagn’: No such file or directory”
    IIIrd step:- Message: “#disable ipv6″

    But still the speed is not increased.

    Any suggestion?

    Thanx

  • Bertalanimre

    Method one worked for me, so I won’t try the rest. ) I was affraid of it because there was no “/etc/modprobe.d/ath9k.conf” file in the system. But creating it and addign the mentioned line fixed it. Thank you!

    None of these worked for me nor did any of the other solutions I found. I have 6 laptops all running Mint10 and 11 except for one on Win7 and one dual booting Win7/Mint12, now Ubuntu 12.04. All of them connect to the net perfectly except for this one, first with Mint12 and now Ubuntu 12.04.  I have spent days trying to get Network manager working with no joy and am now completely sick of trying. The Network Manager devs need to be taken outside and given a good kicking in the real world! Wireless not working properly in 2012? Absolutely no excuse if Linux is to be taken seriously!

         I give a lot of my time setting up networks, fixing PCs and laptops for friends and family. What I don’t do is half a job and then walk away blaming the hardware or whatever. I have finally got it working by changing to an Atheros card that is four years old and hacking the bios in my Thinkpad so it can be used. So that’s three wireless cards later just to get something working that worked fine in 11.04. The bug report about slow wireless in 11.10 and now 12.04 was first opened in August 2011. Still isn’t fixed!

           Ignoring a problem requires far less effort!

          Memory bugs and extesnsions management issues have been ignored for more than a decade by the now mozilla people.

          Passing the buck forward is slightly more effort than ignoring but certainly less than solving the issue

  • Hodor

    Sadly none of those worked for me so far, after 10 seconds of downloading a file, the connection stops and restarts after 3-5 seconds. Trying to disable IPv6 now, hope it’s going to be fine…

    • Hodor

      Nope, no better connection, same problems as before.
      The second alternative could not be tried out by me, because there is no module called “iwlagn” which i could remove or re-enable… :-(
      Any more suggestions how to solve my problem?

  • Ibrahim

    Thank you for this great post. Please note that the second method is not working for  12.04. The reason is that the file name is changed from (iwlagn) to (iwlwifi).

    You can also try this:  

    And finally, it turns out that I was only using wireless to access the repos, which had been heavily bogged down. Great fix for that: Update Manager > Settings > Ubuntu Software [tab] > Download from… [menu] > Other > Select Best Server. If only there were a script to do that…

    I went straight to 3, but instead of fiddling with the terminal I just disabled (“ignored”) ipv6 in the network preferences. Seems to have worked great.

  • Yusuf Ismail

    A shame, I use a D’Link DWA 140 N RangeBooster USB Adapter and both of these do not help with my connection speeds. I have also tried switching off wireless power management, did not help. I have also tried setting IPv6 Settings to Ignore instead of Automatic but this also did not help. I have also installed the proprietary RaLink rt2870 driver and it did not help. I am in a corner with no solution.

  • Larry

     I don’t have ath9k.conf or iwlagn-disable11n.conf in etc/modprobe.d.  Wtf?  This truly bizarre.  I just installed Ubuntu 12.04 on a new system (with an Nvidia GTX 570, it’s possible this is causing all of my many problems).  I have Ubuntu 12.04 on my laptop, upgraded from 11.10 and the internet connection is fine.  What the hell is going on? Any suggestions?

    • aaaa

    • Didi

      I think the module is iwlwifi in 12.04
      So

      sudo rmmod -f iwlwifi
      sudo modprobe iwlwifi 11n_disable=1
      and if that works then
      gksudo gedit /etc/modprobe.d/iwlwifi.conf
      options iwlwifi 11n_disable=1
      The point is in the first command (sudo rmmod etc) type iwl and then press Tab.. should give you the module.. :)

  • Frank van Wensveen

    Running Natty on my HP-550 laptop, I have found that there are some issues with power management that are definitely related to the “slow wifi” problem. After a period of inactivity (e.g. the screen blanks) my USB mouse powers down (the light for the optical sensor  switches off) and access to the laptop via WiFi becomes dreadfully slow.  However, when I hit a key on the keyboard and the laptop “wakes up” (USB mouse light comes on again) WiFi access is restored to its original speed.

    That’s when I use the laptop on AC power. When I run it off the battery, I simply cannot use my USB mouse, as it switches off after about three seconds no matter what i do. And guess what – WiFi is then so slow it needs a tow rope.

    From where I sit, I see a definite relation between slow WiFi (and other issues) and power management.

    the way I fix it was by changing the router settings from N to G if you have a atheros card go inside of the physical router 192.168.1.1 linksys :-)

    i have an hp dv6qe amd quadcore dual amd graphics windows 7 ubuntu 12.04 dual boot.  the first solution did not work.  for the second solution “iwlange” was not recognized.  so far the third solution has worked so far for me on this machine

  • Me

    None of this worked for me. The file  /etc/modprobe.d/ath9k.conf does not exist, nor does the iwlagn kernel module.I haven’t tried to fiddle with IPv6 but AFAIK that’s not active in any form, shape or sizeon my system. I’m not disputing the efficacy of your solution on your system, but itseems to be very hardware dependent.

  • Matt

    Hi,

    Thanks for this. Combining your solution in this blog post (which didn’t work initially) with a comment by ‘Didi’ I managed to get the wireless working at full speed.

    It seems that 12.04 uses the iwlwifi module not iwlagn – amending the commands accordingly worked a treat!

    I’ve blogged about it here – http://www.mattkirwan.com/linux/slow-wireless-connection-ubuntu-12-04-lenovo-thinkpad-x200/ mainly for myself but hopefully anybody else with the same issue will find it useful.

    Kind regards,

  • Vincent

    On my Aspire One D257, only the second method work perfectly on Ubuntu 11.10. On 12.04, that work too, but you have to replace iwlagn by iwlwifi. That stay a little bit slow ( only 2.1 Mo/sec ) but it’s usable.

  • Sisternotes

    Yeah, the first method worked (i.e. has improved my browsing speed). I installed Ubuntu 12.04 alongside Windows7 from a live USB (mistake, should have done it from the windows installer…) on a Toshiba Satellite P755. Thanks!

  • Daniel Fairchild

    Thank you so much, method 1 worked really well for me, increasing my throughput by a factor of around 10

  • MikeH

    I’m new to Ubuntu. In the first method how do you add
    “options ath9k nohwcrypt=”? DO you enter this as a 2nd terminal command? Or add it to the ath9k.conf text document that opens up? Or do you add it to the file name? Completely stuck

    for those who worry that the file /etc/modprobe.d/ath9k.conf does not exist – don’t worry. just create the file and put the one line in it per author’s suggestion. completely fixed unbearably slow wifi for me.

  • Ajit de Silva

    The first method worked for me. I will note there was not an extant ath9k.conf so I created one with your line in it. rebooted and worked fine. In the gui I did see the ath9k driver mentioned so I felt this approach seemed relevant to my case but is that always true; that is are all ubuntu wifis using this file? I just moved from 12.04 LTS and before that I had the an earlier version of LTS that came installed on my dell computer.

    wicd saves the day!!

    Running Mint 14 and the internet has been desperately slow(!). I disabled Java and pictures and pages were taking minutes to upload. (Not kidding) I searched a lot online only to find that the answers were focusing on this or that, but the problem wasn’t getting fixed. (Except someone said that it stopped when they changed the router).

    I tried disabling the IPv6. I tried changing the Firefox setting for attack sites. I tried installing the pnsd (it’s still installed). Nothing. I found the driver for this particular Athenos model and installed the .inf file through the Windows Wireless Drivers tool, it installed. Still nothing. The internet was hardly coughing up text. -___-

    Then I read on some forum that Athenos is particularly problematic. That’s what I have for wifi. Also a recommendation to use the program wicd and that it’s better for wifi than the Network Manager that comes with Mint. I installed wicd through the Software Manager (it took a while) and after toggling the Properties and changing it to WPA1/2 (passphrase) and some refreshing… it worked!!! :D

    I just opened youtube.com and amazingly everything was downloading as normal. Alhamdulillah. I’m running an Emachines e527. Hope this helps someone. :)

  • Anon

    You do realize that ath9k is a system-specific driver that probably more than half ubuntu users won’t have installed, right? That makes #1 less than uninformative. This post is very annoying because you don’t bother to explain what’s being suggested, you just post a bunch of snippets that won’t even be useful to most users. Perhaps it’s because you don’t understand it either?
