Hi Guys
I'm running 11.04 on 3 machines; a Dell laptop, an Acer laptop and an Acer
netbook.
The Dell and the netbook both use the Broadcom STA wireless driver. Today I
performed a routine system update, via Update Manager, and now I have no
wi-fi on the machines running the Broadcom driver. No wireless networks are
detected.
The Dell wi-fi works fine if I boot it using Windows 7, and my Kindle and
the non-Broadcom Acer laptop both detect my network, so I am confident that
there is no problem with any of the network cards or my router.
It appears to me as if something in a very recent update is the root cause.
Does anybody have any ideas for a solution?
Regards
Nige
If you did not notice what packages were being update, you can use the
software centre to show you a list of all the packages added and upgraded.
A guess would be a kernel upgrade, or kernel modules. If you select the
older kernel when booting the computer you can quickly test if this is the
cause. You should still have the previous kernel installed unless you
specifically asked Ubuntu to remove it.
Thank you.
