Even more promising than the Alpha versions, as expected. Everything is a lot more stable, Firefox 3 is warming up to us and it is overall a good experience.
Although most peoples 1501's will work with no hiccups in the beta, we did experience an issue with our install. When trying to format the disk and install fresh, it would not format. There was a known bug that locked any previous partitions. To wipe the drive and start with the whole thing unallocated, it was necessary to create a new disk label by going to System->Administration->Partition Editor and in Partition Editor selecting Device->Set Disklabel. This is easy but should not be necessary. Hopefully by the official release this will not be needed for anyone and it will work the way it is supposed to.
The Driver Manager still has a bug when installing the driver. The Broadcom B43 firmware cutter will not work when used through the Driver Manager. In order to install B43-fwcutter you need to use the terminal.
In a terminal Type:
sudo apt-get install b43-fwcutter
This takes care of the driver, and we can see wireless networks. If you're lucky, you can connect to them too, but many of our readers have been reporting that connecting just keeps going and going with the connecting animation seemingly going on forever with no results at all.
For the majority of users, the most recent updates that include the new version of "network-manager" will fix this issue. For those of you who are still encountering issues after updating completely, congratulations you have found the fix.
This will uninstall the unworking version of network-manager, that screws up and replace it with the old one which works without flaw.
Download the working version - Type in a terminal
sudo wget http://download38.mediafire.com/2bdi9e0d0l7g/jyjze9dd7t9/network-manager_0.6.6-0ubuntu1_i386.deb
Downgrade - Type in a terminal
sudo dpkg -i network-manager_0.6.6-0ubuntu1_i386.deb
If you followed the instructions, you now have wireless working perfectly. Simple, two commands, copy and paste, you don't even need to reboot. Hope this is satisfactory to everyone in need.
All other categories (ATI driver, card reader, modem etc.) have remained the same since Alpha 6.
Please tell me how these things work for you in the comments, a few of the testers have already confirmed it works well but I want to hear from everyone else. Keep up to date, good things to come soon.
