Post Wireless problems in openSUSE 11.1 on Compaq Presario V5315WM laptop


Hi,

I have been using the openSUSE forums to try and fix the major problem of not being able to connect to my home wireless network in openSUSE. (It works fine in Windows Vista, for the record.)

When I used the following code to see if the disabled channels 12, 13, and 14 were the root of my problem, I got "Permission denied," which I don't understand because I was running it under root account...

- START -
Channels 12,13 and 14 are disabled (wrong regulatory domain)
As of openSUSE 11.0 most wireless drivers depend on mac80211. Regulatory domain handling has been implemented in the wireless stack, but it is not available until kernel 2.6.27. In order to stay FCC compliant the stack enables only the minimal subset of available channels (1-11 in the bg-band). For example in Germany the channels 12 and 13 are allowed too but disabled by default. These channels can be enabled by overwriting the regulatory domain (allowed parameters are US, EU and JP):

echo "options cfg80211 ieee80211_regdom=EU" > /etc/modprobe.d/cfg80211
- END -

Anyway, has anyone else had trouble connecting to wireless with openSUSE 11.1? If so, how did you fix it?

Some shared solutions would be greatly appreciated!

P.S. I am using KDE, not GNOME.

can you post the output of uname -a please? the problem looks like it could be an old kernel version but I just want to check.

Wirless Working For Me on Two Computers

In fact, OpenSuse is one of only a few that do work on my PCs. I have it loaded on a Compaq Presario CQ50-110US. I also have it loaded on a Acer Aspire with a Atheros Comm Inc AR242X 802.11abg Wireless PCI Adapter. I don't know the card for Compaq at the moment but if you need it I will gladly get it for you. It worked out the box for both. Just went into network manager, added the WEP key and it worked.

Post uname?

jstephens84,

What is uname? I'm a Linux newbie, so I apologize for slowing down the "help process" haha...

Terminal code? Help me out.

Thanks.

uname is a command that will display information about the kernel. it is typed in a terminal like xterm, or rxvt or while in a bash shell.

I am having exactly the same issue on my Compaq Presario R3000.

The results of uname -a:
Linux linux-h7p0 2.6.34.7-0.5-desktop #1 SMP PREEMPT 2010-10-25 08:40:12 +0200 i686 athlon i386 GNU/Linux

Running network manager shows no active wireless points, Win 7 on the same machine works fine.
