[Bug 621265] Re: Slow Wireless Connection in Intel 3945abg
It has been some time since I posted here, but I finally took the time to update to 12.04. I did a clean install and had the same slow Wi-Fi problem out of the box. So I can confirm that Bug #621265 affects Ubuntu 12.04 Precise Pangolin too. I then did the same change documented previously of removing NetworkManager and installing Wicd. All is working once again. All that said, this appears to not be a GNU/Linux, driver, or Ubuntu issue rather a Network Manager package issue since the bug is so easily fixed by merely replacing that package with a comparable one. Here are the steps I performed: NOTE: Plug in a wired ethernet connection while completing these steps or reverse the order of the next two steps if one is not available. $ sudo apt-get remove network-manager $ sudo apt-get install wicd NOTE: To get the SysTray Icon to show up, you have to follow the tip from here: http://ubuntuforums.org/showthread.php?t=1762663 $ gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" NOTE: Or for a more involved, probably more correct, way to get the SysTray Icon to show up, follow the steps here: https://bugs.launchpad.net/wicd/+bug/761326/comments/2 Reboot and log back in. You will have to reenter all of your saved network credientials, so it is a good idea to swap managers as soon as the need is identified.

[Bug 621265] Re: Slow Wireless Connection in Intel 3945abg
I upgraded to 2.6.38-10 the day it came out and I didn't have any trouble with it. Last night I did a BIOS update on my Acer Aspire 5920 and then this resurfaced. I can also confirm that by backing out to 2.6.38-8 also works for me. Upon reading the release notes, there seems to have been several things done in the BIOS for my machine regarding the WLAN between the original shipping one and the latest one which I just installed. Since the BIOS updates for this system require a functioning M$ Vista OS to install them, switching them out is a bit of a pain. If there is any benefit in it, I will do what I can. I am ready to assist in troubleshooting this, but I am not familiar enough with the inner workings of Linux to know where to start. I am going to try some simple swaptronics by building and installing the latest compat-wireless to see what I get.

@CarlosRuiz_globalqss This is deffinately a similar solution. If you are still not noticing speeds that you would expect, there are several reasons that could be causing it. I was batteling my WAN connection during testing, so I always had to double check with a machine running a different OS.

[Bug 621265] Re: Slow Wireless Connection in Intel 3945abg
I wrote a shell script to download and build each compat-wireless version. I have attached the script for anyone that wants to see it. For maintenance purposes, the script removes the downloaded .bz2 files and any decompressed version that failed to compile with my current setup. I reviewed the logs and noticed starting with compat-wireless-2011-02-23 and running up through compat-wireless-2011-04-14, I was receiving: compat-2.6.39.c:93:4: error: ‘TASK_INTERRUPTIBLE’ undeclared (first use in this function) I already found the fix to this as described in #353, it was simply the addition of "#include " to the file. At this point I had compat-wireless-2011-03-18 working at full speed and compat- wireless-2011-04-26 working with the slow down. I was determined to find the latest version that worked and in turn the first version that didn't. To start, I split the difference and started working on compat- wireless-2011-03-25. With the ‘TASK_INTERRUPTIBLE’ error fix applied, it ran at full speed. Again splitting the difference and working on compat- wireless-2011-03-29, with the ‘TASK_INTERRUPTIBLE’ error fix applied, it ran at full speed. Yet again splitting the difference I began working on compat-wireless-2011-03-31, with the ‘TASK_INTERRUPTIBLE’ error fix applied. However this time it failed to run at full speed. Getting close now. Down to only one left, compat-wireless-2011-03-30 was either going to be the latest that worked or the first that failed. With the ‘TASK_INTERRUPTIBLE’ error fix applied, I saw a new error pop up: p54spi.c:652:2: error: implicit declaration of function ‘irq_set_irq_type’ The fix ended up being to copy compat- wireless-2011-03-31/include/linux/compat-2.6.39.h into compat- wireless-2011-03-30. This version compiled now, but failed to run at full speed.

For those that haven't and would like some more information about it, take a look at: http://en.wikipedia.org/wiki/Binary_search_algorithm My final analysis is, follow the instructions in #353 and use compat- wireless-2011-03-29 instead of 2011-03-18 or 2011-08-27. If there is anyone from the compat-wireless folks monitoring this thread, the change that is effecting those of us with an Intel 3945ABG occurred between compat-wireless-2011-03-29 and compat- wireless-2011-03-30. A random sampling of versions between compat- wireless-2011-04-26 and compat-wireless-2011-08-27 either still had the slow down, wouldn't compile, or locked up my system completely. ** Attachment added: "Shell Script to download and build compat-wireless" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/621265/+attachment/2354447/+files/getNbuild.sh -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/621265 Title: Slow Wireless Connection in Intel 3945abg To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/621265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I know these are newbie questions and I thank you for your help and patience. Previously I had installed only the linux-image-xxx.deb from #270.

[Bug 621265] Re: Slow Wireless Connection in Intel 3945abg
As I mentioned earlier, I have been a linux distro user for years, but have never had to delve into the building of individual kernel modules. So I thought I would post this lesson of what NOT to do. I followed the README instructions and issued the commands below: $ ./scripts/driver-select iwlwifi $ make $ sudo make install $ sudo make wlunload $ sudo modprobe iwl3945 and on the modprobe I received: FATAL: Error inserting iwl3945 (/lib/modules/2.6.35-27-generic/kernel/drivers/net/wireless/iwlwifi/iwl3945.ko): Invalid argument with the end of my dmesg log showing several: iwlcore: disagrees about version of symbol iwlcore: Unknown symbol (err -22) Thinking that I may have not uninstalled enough kernel modules before trying to install the new iwl3945, I rebooted the machine. When the machine was back up, I had the exact same messages the dmesg log. I was able to get back to the my original (i.e. slow) state by issuing: $ sudo make wlunload $ sudo modprobe iwl3945 The first step in the lesson above, driver-select, is a shortcut and sped up the compile and install times dramatically. As I was investigating this problem, I found that this shortcut does not build the mac80211 module and the "disagrees about version of symbol" errors are due to the original mac80211 module not being compatible with the new iwlcore and iwl3945 modules. The correct steps are below: $ ./scripts/driver-select restore $ make $ sudo make install $ sudo make wlunload $ sudo modprobe iwl3945 I now have a fully functional iwl3945 module loaded and consistently getting speeds comparable to my wife's M$ machine. 5.14 Mb/s Download 0.65 Mb/s Upload 35 ms Ping Everything seems to be stable. @Andy Whitcroft Thanks for the work on getting this fixed. @Radosław Piliszek Thanks for the patience and guidance. @s0undt3ch Thanks again for the assistance.
