Upgrade to Helena ==> Boom

[digitxp]

Hi everyone (this is my first post to a Linux forum ),
I upgraded to Mint 8 the haphazard command-line way (I wanted to keep my apps).
(What I did:

1. Ran

   Code: Select all

   gksu gedit /etc/apt/sources.list

   and replaced all occurrences of “gloria” to “helena”, and all occurences of “jaunty” to “karmic”.
2. Ran this:

   Code: Select all

   apt update; apt install mint-info-main;apt install mint-meta-main;apt upgrade;apt dist-upgrade;apt install mint-meta-main;apt upgrade;apt dist-upgrade;apt install mint-meta-main;

   (as per instructions from the blog)
3. Rebooted after it was all done.

)
Now all of a sudden, my WiFi doesn't work. There was an icon (the usual network icon) that said "NetworkManager not running".
I searched on Google, then I tried running

Code: Select all

sudo /etc/init.d/NetworkManager start

which caused the network icon to be replaced with a menu that didn't have any wireless networks listed, only VPNs.
I have a Netgear WG311v2 (PCI) and a WG111 (USB).
Any help at all is appreciated (to add density, I backup my USB with Back in Time on it and it's my test computer ).

When I ran live CD Mint 8 it doesnt recognize USB wifi, Mint 7 does, and I dnt know what to do just like you!

I guess restarting router/modem might work ?
