Hello,

I notice that after about 10minutes having boot up my HP pavilion, my wireless becomes unstable.

I also have packet loss when I do a ping :

Maybe I don't have the correct wireless driver installed ?

I have the following installed :

[root@jonashp ]# yum install iwl2030-firmware
Loaded plugins: langpacks, presto, refresh-packagekit
Package iwl2030-firmware-18.168.6.1-9.fc17.noarch already installed and latest version
Nothing to do


What else can I do ??

what is your distribution and which version ?
what is the kernel version?

Fedora 17 - Gnome3

Linux jonashp.jocan.local 3.6.10-2.fc17.x86_64 #1 SMP Tue Dec 11 18:07:34 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

hp pavilion dv7 has two models with different processors amd or intel which one do you have? this will determine exactly the model of your wireless device because data you presented are not enough
check the following link....
http://en.wikipedia.org/wiki/HP_Pavilion_dv7

I am still trying to identify your wireless card accurately..so please help me

Hello,

my model is not present on the wiki. I have pavilion dv7-7180eb.

Should be Intel processor (i7-3610QM) and Intel wireless.

do you have any windows installed on the notebook?

Windows 7 (dualboot with Fedora)

try to identify the wireless card from windows 7
right click on computer icon the click >>> Properties then >>>> Device Manager..

Intel Centrino Wireless-N 2230

checkout the following link
http://www.backtrack-linux.org/forum...ad.php?t=54302

I've seen that post. The ucode-file is installed on my system.

this is the file u want
http://intellinuxwireless.org/iwlwif...18.168.6.1.tgz
After opening the archive, I copied the iwlwifi-*.ucode file to /lib/firmware/
Then I ran `modprode -r iwlagn` followed by `modprobe iwlagn`

you have to check the version of the file may be the link contains an updated driver which fixes the problem

type the following command in a terminal
this is to check the version of file..may be the newer file fixes the problem.

[Jonas@jonashp ~]$ ls -l /lib/firmware/iwlwifi-*.ucode
-rw-r--r--. 1 root root 707392 Jul 20 17:51 /lib/firmware/iwlwifi-2030-6.ucode
