Kubuntu 11.04 Wireless Crashes

[hamada969]

Hello Everyone,

I have updated my Kubuntu to version 11.04 recently. Every time now I connect to wireless it crashes , sometimes instantly and sometimes a bit later after it has started. When I am connected to LAN all is fine. Please advice me on what to do. My laptop is HP Pavilion DV6 2155ee.

Thanks

The make and model isn't enough, and even if I googled it there is no guarantee that the wifi chip is the same in all of that make and model. So, in a Konsole issue

lspci | grep Network

and report back what is output.

Ah, Jockey probably tried to install firmware-b43--installer instead of firmware-b43-lpphy-installer.

What you need to do is plug your computer into your wireless router via a short Ethernet cable to an Ethernet port in the back of your wireless. It should generate an Internet connection automatically.

Then, first, uninstall "firmware-b43-installer" and then install "firmware-b43-lpphy-installer". Then reboot.

After i uninstall and install firmware-b43-lpphy-installer I get:

End of the error looks like this:

It seems that the card is not supported..

mmm... You could uninstall "firmware-b43-lpphy-installer" and try its predecessor, "firmware-b43-installer" instead. They both install the b43-fwcutter, which extracts the BIOS from the chip itself and then uses it to connect, but the lpphy is the latest version. Perhaps the older one will work.

But, in the past, for most BCM43 wireless chips all one needed to do was
sudo apt-get install b43-fwcutter
and it would do everything necessary to get the chip working.

I believe 11.04 has buggy wireless software. I had similar problem with 11.04, which cleared up when I went to 11.10 beta.

Re: Kubuntu 11.04 Wireless Crashes

It's probably a good idea to go to 11.10 anyway. In another six months the 12.04 LST will be released.

Also, there is an update available for "network manager" which is new since the 11.10 beta release.

I don't keep up with KNetworkManager, which I replaced with wicd long ago. It will make a connection before KDE starts up or even when KDE is not running. There are threads on this forum about how to replace KNM with wicd. Basically, it is installing the five basic wicd apps FIRST, then uninstall ALL of the KNM and its components. Configure wicd for your wireless essid and password. Then, either reboot or restart the network.
