Comment 165 for bug 541620

I have a Lenovo IdeaPad S205 with RaLink RT3090 wireless interface.

With Ubuntu 11.04 "Natty Narwal" wifi doesn't work after install. The modules rt2860sta and rt2800pci are conflicting. Manually blacklisting one module and using the other one didn't work either.

However after upgrading to ubuntu mainline kernel v2.3.39-rc3 wifi works using module rt2800pci which contains significant updates by the manufacturer in 2.3.39.

There is a problem left in combination with module ideapad_laptop which processes acpi events to activate/deactivate wifi. However a workaround for this problem exists.
