Fails to connect to Wi-Fi several times after resume from suspend -- Ralink RT3090 rt2800pci

After wake-up from suspend, I'm not connected automatically to wlan. Network-manager does automatically attempt to connect but I get a password dialog (containing the correct password). Upon confirmation it retries, fails after ~8 s, and shows dialog again. By 3-5 retries it will succeed.

I'm on Quantal on a Lenovo S205. In Precise I didn't have this problem. Nothing has been changed in the wlan configuration.
