Upgrade failure

[bingo23]

Had Ubuntu 9.01 in Windows 7 as a Dual Booty - no problems.

When upgrade to 10.04 attempted the following errors occur:-

1. Missing Resources warning - " The Networkmanager Applet could not find some required resources. It cannot continue."

When I click OK wireless connection is totally lost with no means of reconnecting.

2. Download progresses but freezes at the download of "Preparing memtest86+"

Have tried no less that 6 times !!!!!!!

Hopefully, that's a mistype and you mean 9.10? If you are having wireless problems, you can download the alternate install cd and upgrade from there. Have you made sure the livecd works with your wireless?
