Ubuntu - update kernel breaks wireless

[Robor]

I've gone through this before with kernel upgrades and have always been able to use the instructions HERE (I do use the latest versions of all files though) to get it working again. I am trying now and when I issue the make command I'm getting a spew of errors. I did an apt-get for make and linux-headers. Here's what happens...

gcc is not installed.

$ sudo apt-get install build-essential

Ummmm, no idea.

 

[Robor]

Hmmm... Tried 'putting the firmware in place' and get an error. There's no such thing as /usr/lib/hotplug in Dapper. Apparently Dapper and Breezy don't store the firmware in the same place?

 

[xtknight]

I think it's here instead?

$ ls /lib/modules/`uname -r`/kernel/drivers/pci/hotplug

 

[Robor]

I'm not sure. I did some googling and one person mentioned /lib/hotplug? Here's the output of that command...


robor007@Home-T42-Ubuntu:/tmp/wifi/fw/ipw2200-fw-3.0$ ls /lib/modules/`uname -r`/kernel/drivers/pci/hotplug

acpiphp_ibm.ko cpcihp_generic.ko cpqphp.ko ibmphp.ko pci_hotplug.ko
acpiphp.ko cpcihp_zt5550.ko fakephp.ko pciehp.ko shpchp.ko

The instructions here have you create a directory.

http://www.oreillynet.com/onlamp/blog/2...10/fedora_core_2_linux_and_centri.html

It looks like you put them in there only to be copied to /lib/modules/.... later on?

Just put them in the /lib/modules place and see if you can modprobe the driver.

 

[Robor]

I'm not sure where the firmware is supposed to go. I looked in /lib/modules and there's a directory for the current and previous kernels. Here's what I've got there...

robor007@Home-T42-Ubuntu:/lib/modules$ ls
2.6.15-23-386 2.6.15-25-386 2.6.15-26-386 2.6.15-26-686
robor007@Home-T42-Ubuntu:/lib/modules$ cd 2.6.15-26-686/
robor007@Home-T42-Ubuntu:/lib/modules/2.6.15-26-686$ ls
build madwifi modules.dep modules.ofmap modules.usbmap
include madwifi-ng modules.ieee1394map modules.pcimap net
initrd modules.alias modules.inputmap modules.seriomap volatile
kernel modules.ccwmap modules.isapnpmap modules.symbols
robor007@Home-T42-Ubuntu:/lib/modules/2.6.15-26-686$

Firmware goes in /lib/firmware

 

[Robor]

I've done a 'tar zxvf ipw2200-fw-3.0.tgz' to /lib/firmware/2.6.15-26-686 and /lib/modules/2.6.15-26-686. Issuing a modprobe just drops me back to the next line with no response - no error or output. My wireless card is listed in a ifconfig and in the 'Networking' GUI. I just don't get an IP from my router.

Like I said, I've gone through several kernel upgrades that broke my wireless but going through the instructions in my original post and using the latest versions always worked. Now I'm borked... :-/

it broke your intell 2200? I've not had any problems with Dapper and my Intel 2915(same basic driver)

Yep. Working fine between home (wireless) and work (wire). Applied updates (including new kernel) at work and no more working wireless at home. It's happened before several times under Breezy and I could always repair it with the instructions in the link above. I've done a kernel update or two under Dapper and it didn't break my wireless until now.
