Weak wireless problems intel 2200bg with 8.04

[jp0213x]

Hey all,

I am a newbie to Ubuntu, but after doing a fresh install of Ubuntu and apply all the update, I noticed that my signal strength is not all that strong, the signal tends to jump and down and usually stays in the 50% range I don't have this problems when xp is loaded on my laptop, this only seem to be a problem in Ubuntu. The hardware adviser does detect my 2200bg card and will connect to my D link router just not with a good signal. I've searched the forums for this problems, this seems like a common problem some people are having, but I could not locate a real true fix. I am not a real fan of the intel 2200bg cards but does anyone have any suggestions?

Thanks

Please post the output of these commands so that we can figure out what to do:

lshw -C Network
lspci -nn
uname -m
dmesg | grep -e iwl -e ipw

Also, are you able to get online via ethernet at least temporarily (this is good to know so that we can tailor instructions to your situation)?

I am able to get online via ethernet, thats not a problem at all, that works great. For some reason I am having problem getting an internet connection even though it shows connected. Here is the info you are looking for.

Let me know if there anymore info you need, thanks!

[pytheas22]

Thanks for the information. Please run these commands (make sure you're plugged into ethernet first), which will install ndiswrapper to drive the card (using Windows drivers). Hopefully that will work better than the ipw2200 driver:

sudo apt-get install ndiswrapper*
echo 'blacklist ipw2200' | sudo tee -a /etc/modprobe.d/blacklist
wget http://downloadcenter.intel.com/confirm.aspx?httpDown=http://downloadmirror.intel.com/16617/eng/12.0.4.0_X_Drivers.zip&agr=&ProductID=1637&DwnldId=16617&strOSs=&OSFullName=&lang=eng
unzip 12.0.4.0_X_Drivers.zip
cd Disk/XP/Drivers/x32
sudo ndiswrapper -i w29n51.inf

Now reboot and see if your wireless works better. If it still doesn't, please post:

dmesg | grep -e ipw -e ndis
cat /etc/modprobe.d/blacklist | grep ipw
ndiswrapper -l
lshw -C Network

I seem to be running into the problems with downloading the drivers, this is what I get below:

Not to go off subject, I had to reboot because of sound problems and I realized that my wireless nic is disable, how do I enable the wireless nic again to do more testing?

[gamerteck]

First remove the drivers ndiswrapper just installed

ndiswrapper -e w29n51.inf

Then remove the blacklist from ipw2200

sudo sed s/"blacklist ipw2200"/ipw2200/g /etc/modprobe.d/blacklist

Reboot

[pytheas22]

I'm not sure why the drivers don't want to download...maybe wget doesn't like the way that Intel's site serves its files. I was able to download them manually however and put them on my site, which should work with wget without a problem. Please try following these steps instead, which should work (don't worry if you already ran some of them successfully once; just run them again):

sudo apt-get install ndiswrapper*
echo 'blacklist ipw2200' | sudo tee -a /etc/modprobe.d/blacklist
wget http://burnthesorbonne.com/files/Intel_ipw2200_x32_drivers.tar.gz
tar -xzvf Intel*
cd Intel_ipw2200_x32_drivers/
sudo ndiswrapper -i w29n51.inf

That should work better.

As the poster above says, removing ndiswrapper from the blacklist should get you back to where you currently are, using the ipw2200 native driver but with unreliable performance.

Ok so I rand the cmd line to remove the blacklist and this is what I got.

# This file lists those modules which we don't want to be loaded by
# alias expansion, usually so some other driver will be loaded for the
# device instead.

# evbug is a debug tool that should be loaded explicitly

Now what, my nic is still disabled?

[pytheas22]

First of all, reboot. If after rebooting your card is still not working, run:

sudo modprobe -r ipw ipw2200 ipw2100
sudo modprobe ndiswrapper
sudo ifconfig wlan0

Then wait a few seconds and see if you can connect. If you still can't, please post the output of:

lshw -C Network
dmesg | grep -e ndis -e wlan
iwlist scan
ndiswrapper -l
