For me, downloading and mannualy compiling the rt2860sta driver from the Ralink website solved the problem.
To do this, download and unpack the driver from http://www.ralinktech.com/support.php?s=2 (in my case , I've selected RT2860PCI/mPCI/CB/PCIe(RT2760/RT2790/RT2860/RT2890) Edit the <b>os/linux/config.mk</b> file and change the following settings to 'y': <pre> # Support Wpa_Supplicant HAS_WPA_SUPPLICANT=y # Support Native WpaSupplicant for Network Maganger HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y </pre> Then compile it: <pre>make</pre> And install it: <pre>sudo make install</pre> Please note that these steps have to be performed every time when the kernel is upgraded. -- [lucid] rt2860 frequently fails to connect to mixed mode WPA/WPA2 secured wireless networks https://bugs.launchpad.net/bugs/496093 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
