Sorry for my late response but firmware reinstall failed 2 times (my current internet connection fails). So now i dont even have the firmware ( next to the wireless connections it says no firmware) Its ok to just intsall it again and reboot?or i will have to use the command you send to me?

[wildmanne39]

Hi, you can just reinstall the firmware then reboot but I would use the commands, were you connected to the internet with a wired connection when you ran the commands?
Thanks

No i use broadband but 3 times now failed to reinstall it!
Ok i will try it for 4th time. If it fails again can i install them from synaptic?

Before the command you gave me i had the firmware.Just saying...

[wildmanne39]

Hi, yes you can install it from synaptic but the command does the exact same thing, what errors are showing in the terminal?
Thanks

bzip2: Compressed file ends unexpectedly;
    perhaps it is corrupted?  *Possible* reason follows.
bzip2: Inappropriate ioctl for device
    Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now

E: Sub-process /usr/bin/dpkg returned an error code (1)

Ok firmwate-b43-installer and b43-fwcutter are reinstalled from synaptic and i will now reboot correct?

Edit: dint work :/

[sutibun]

it dint work :/ i can do anything else?
