on 9.10 if you run wget and the file was already fully downloaded the program would wait indefinitely. Works right again on 10.04.Weird. I have always used wget a ton, and didn't encounter any issues with it, starting with Ubuntu 6.10 until now. The only release I skipped was 9.10, but even that I still installed on my laptop, just didn't use it extensively.
I have to put in the ip for my provider, which dint work at all with the first 2-3 releases that had the new Network-Manager (you could poke it into the UI but it had no effect - just tried to get an address via DNS).The thing that helps with network-manager is to check the "Available to all users on this system" (or somesuch) box in the connection properties. That makes it more of an old-style system-wide setting, and is the default in 10.04 as far as I can tell. All I really had to do this time around was assign an IP.
Wireless was already much better in 9.10 than it was in 9.04. Connections (w/ "Available to all users") were established before logon, as it should be. If it behaves the same again, I could live with that.
