I have Knoppix 6.7.1 installed on the HDD of my laptop, dual booting with Windows 7. All was working fine untill I upgraded to grub2. Since the upgrade I have two problems:
a) my wireless nic is no longer detected/active
b) the Windows 7 boot option is no longer on the Grub boot menu

Can anyone advise how/where to track down solutions for either of these?
