wlan0 missing in console after update

[chimanrao]

hi
I updated from 12.10 to 13.04.
Something went wrong in the process and I need to run sudo apt-get install from console.
The problem is that the console is not listing the wlan0 interface.
when I run ifconfig, i see eth0 and lo.

how can I fix this?

What are the outputs of -

lspci -nnk | grep -iA2 net
lsmod
uname -mr

??

Amazing... sorry to interrupt, but I just wanted to point out the elegance of lspci -nnk | grep -iA2 net
Thank you Varun, It's always good to learn something neat

To me, if wlan0 is no visible in the output, it's very likely you're lacking the appropriate driver for it.

Actually, I stole it from Wild Man

Thanks for your replies. I fixed my upgrades by using a live cd and using chroot to get the upgrade happening correctly.
Hugely disappointed by 13.10, some basic stuff like network manager is not showing up by default, makes it difficult to convince non-techies to use this OS, they expect consistent behaviors after upgrades.
