    Just installed Jaunty RC -NO WiFi

    It worked fine with Intrepid.
    Now I have now wireless. Any ideas?

    Did you try reinstalling drivers?

    More info:

    root@SOUNDWAVE:~$ sudo ifconfig wlan0
    wlan0 Link encap:Ethernet HWaddr 00:11:50:50:89:ff
    BROADCAST MULTICAST MTU:1500 Metric:1
    RX packets:0 errors:0 dropped:0 overruns:0 frame:0
    TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:1000
    RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

    root@SOUNDWAVE:~$ sudo ifconfig wlan0 down
    root@SOUNDWAVE:~$ sudo ifconfig wlan0 up
    SIOCSIFFLAGS: No such file or directory
    root@SOUNDWAVE:~$

    So, basically it "kind of" sees the card. but I cannot bring the interface up.

    I'm not 100% sure how to reinstall the drivers.

    Well this is exactly why I don't use Linux. I want my install to work. This Broadcom card is nearly 3 years old. There is no reason why it shouldn't work after the install. I followed all those steps (there were many) and it did not work. Unreal. I spent 5 hours working on a wifi card driver with no results...just like I did in the Mandrake world a decade ago. I'm hooking up the other HDD and once again feeling as though Ubuntu\Linux is not ready for prime time. IMHO

    You should take a look at this just follow the steps that kevdog posted.

    Just a clarification to the original poster. Drivers as you call them are actually kernel modules. That means anytime you go to a new kernel (such as in the case of moving from intrepid to jaunty) you need to reinstall the kernel modules. This means previously installed kernel modules or drivers need to reinstalled into the new kernel. If you dont want to do this, when booting - select the old kernel in grub during the first few seconds of the boot process. Again with linux there are internal and external kernel modules. Internal modules come with the kernel, external ones the user adds later (such as ndiswrapper). Some modules are dropped and no longer supported and others are added with each new kernel. Hence internal modules may change with each new release(example intel video driver i810). External kernel modules always have to be reinserted or reinstalled with each kernel upgrade.

    I hope I made myself clear.

    It was a clean install. Intrepid was blown away before Jaunty.
