Ok, it seems clear where we must look: phy0 -> rt2x00lib_request_firmware: Error - Current firmware does not support detected chipset. NetworkManager[1038]: <warn> (wlan0): firmware may be missing.
Let's look at what you have: md5sum /lib/firmware/rt2870.bin Bug 782752 seems to be about the same problem and has identified a working firmware. But while it would be nice if that worked for you it might be better to look whether the newest firmware already in ubuntu works. We want to fix this for everyone out of the box after all. https://launchpad.net/ubuntu/+source/linux-firmware/+publishinghistory currently newest: https://launchpad.net/ubuntu/oneiric/+source/linux-firmware/1.53 the changelog says this is up to date till commit: http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=commit;h=ae524638c277301a83daf126aaaf880738e2474b This means it includes the shiny new firmware posted to the rt2x00 mailing list: http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2011-March/003382.html which subsequently was commited here: http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=commit;h=5c10f3d6a5c76dca943ae68926b602bd0a1eae3 Maybe you could just try by extracting rt2870.bin from here: https://launchpad.net/ubuntu/oneiric/+source/linux-firmware/1.53/+files/linux-firmware_1.53.tar.gz and copy it in /lib/firmware (rename the old one to e.g. rt2870.bin.disable) About why there are so many drivers: Basically there are two sets of drivers, the "legacy" drivers developed and open sourced by Ralink and those (mainly - for new devices rt2800usb and rt2800pci) developed by the rt2x00 project (looking a lot at the legacy sources to make up for missing specs and getting answers from Ralink engineers and also increasingly getting patches sent by Ralink engineers). The Ralink drivers are monoliths (look at the size) and do not fit the linux wireless infrastructure (mac80211 stack). For that reason they will never make it into the kernel proper. They will stay in staging until they are deleted. There aren't any big differences between what is in staging and what is available directly from the Ralink website, architecturally speaking.
