The "problem" about the wireless settings disappearing after a reboot can be fixed by adding the commands to /etc/rc.d/rc.local, as has been explained in many threads.
Any way to automate that in the future for newbs?
Re non-wireless internet connection probs on reboot: I actually wonder whether a lot of the VL newbies may be doing the network config part of the install incorrectly - such as choosing something other than DHCP (95% of workstation Internet users would use DHCP). Maybe that screen needs a bit more explanatory text - I don't know - just an idea....
