Wireless performance degrading.

[kelean]

I have a dell latitude d800 laptop. It has a pro/wireless 2200 card. When I installed saltimbucca 3 weeks age the wireless was great and had very few drops. It would stay connected for a couple of hours. But in the last few days the wireless is getting worse. When I start the machine it often does not connect It will connect for a couple of minutes and drop. When I try to reconnect it will not and give me a statement of not connected because of a bad password or it cannot obtain an ip address.

I am dual booting this machine with XP and have no issues with the wireless. Linuxbbq has been the best with my wireless than any other linux distro that I have tried.

What can I look at or try to fix this. I do not to go back to windows. Thanks Kelean.

are you using network manager?
if so, try maybe running CENI,... it will ask to disable network manager, do so and see if it works any better, i found apart from a lack of a status icon to be great - no complaining after lid down.
if it's no better, simply run ceni again and at the bottom - activate network manager.

kelean,
might be due to a new kernel; can you post:

Code: Select all

uname -a
lspci --nnk 

thanks :)

Or easier: try the Liquorix kernel http://liquorix.net/ and compare.

I also have poor wireless at the moment, and have heard of the iwlwifi package to be at issue.

I think I am using nm so I will give it a try. Thanks

Hi,

I have liquorix enabled and they have their own driver for your card:

Code: Select all

apt-cache policy firmware-ipw2x00 
firmware-ipw2x00:
  Installed: 0.36+wheezy.1
  Candidate: 0.36+wheezy.1
  Version table:
 *** 0.36+wheezy.1 0
        500 http://http.debian.net/debian/ unstable/non-free amd64 Packages
        100 /var/lib/dpkg/status
     0.36+nmu2 0
        500 http://liquorix.net/debian/ sid/main amd64 Packages

I'd say have a try with Liquorix.

[machinebacon]

Or;

Code: Select all

ins linux-image-siduction-686  linux-headers-siduction-686  

(replace 686 with 686-pae if you use PAE). This will bring you the newest kernels.

[kelean]

Or;

Code: Select all

ins linux-image-siduction-686  linux-headers-siduction-686  

(replace 686 with 686-pae if you use PAE). This will bring you the newest kernels.

I installed the newest 686 kernel but I messed up and only installed the kernel and not the kernel. I recived some warnings about the headers were not installed. Went and installed the headers. rebooted with the new kernal and it froze and the screen gets all weird.

Now I am stuck. I am sure there is something simple that I am missing but cannot remember.

[machinebacon]

No fear, the old kernel is still there in your GRUB (if things went normal)

Boot into the older kernel (3.6-5) and log in normally, then open a terminal:

1) enter: upd
2) let it perform the update
3) enter: sudo kernel-remover
4) select the "new" kernel and remove it
5) repeat the installation of the new kernel:

Code: Select all

ins linux-headers-3.7-2.towo-siduction-686 linux-image-siduction-686 linux-headers-siduction-686

(a bit forceful but we want that precious kernel)

http://manual.siduction.org/en/sys-admi ... upg-en.htm

[kelean]

I ran sudo kernel-remover and it said there was only one kernel installed.

[machinebacon]

can you check which is running now?

Code: Select all

uname -r

Please anyway update and re-install like written before, if you get warnings about some firmware missing, copy-paste it here (usually it's harmless, like the r8169)

[kelean]

uname -r 3.6-5.towo-siduction-686

[machinebacon]

So the new kernel wasn't downloaded. Don't forget to run a "upd" before installing the new one.

[kelean]

I am not running running linux-image-3.7.3.towo-siduction-686 kernel as it will not boot. I am running the older kernel. Grub has both kernels listed. I also tried to boot it in recovery mode but also froze.

[machinebacon]

Then let's boot into the old one and remove the new kernel that doesn't work with "sudo kernel-remove" and then have a try with installing the Liquorix kernel.

[kelean]

But when I try to sudo kernel-removlled it says only one kernel instaled nothing to do. I will try to install the Liquorix kernel.

[kelean]

Um..........I tried to add the Liquorix repo but not sure where to do it. Things look different from the last time I edited the sources list.

[machinebacon]

1)

Code: Select all

sudo leafpad /etc/apt/sources.list.d/bbq.list

2) add this line:

Code: Select all

deb http://liquorix.net/debian sid main

3) save and exit
4)

Code: Select all

upd 
sudo apt-get install '^liquorix-([^-]+-)?keyring.?'

installs the keyring
5)

Code: Select all

ins linux-headers-liquorix-686 linux-image-liquorix-686

installs the header and image

I'm on 64bit right now, but the commands should be okay ^

[kelean]

I installed the Liqurix kernel using the commands you posted and I have the same results. It starts to boot like normal and actually got to the login screen. Thats when it froze and the screen started very odd colors and getting very bright.

Just for shits and giggles I ran the kernel remover and it says I only have one kernel installed,
