[Bug 496093] Re: [lucid] rt2860 frequently fails to connect to mixed mode WPA/WPA2 secured wireless networks

[Dries Harnie]

** Description changed:

- The rt2800sta module in the lucid kernel has failed to connect to my
- wireless network (which uses WPA2) 8 out of 10 times i've tried to
- connect to it, while never having any problems with unsecured networks.
- karmic's module worked flawlessly, however.
+ The rt2860sta module, included with Ubuntu Lucid Lynx (10.04) cannot connect to mixed WPA/WPA2 networks.
+ This driver is used in most EeePCs.
+ This issue is fixed in the 2.6.33 kernel, unfortunately this kernel is not yet available in Lucid.

+ To check if your wireless chipset is indeed the RaLink chipset that is affected by this driver, execute the "lspci -vnn | grep RaLink" command.
+ It should display something close to the following:
+ 
+ $ lspci -vnn | grep RaLink
+ 01:00.0 Network controller [0280]: RaLink RT2860 [1814:0781]
