I have Linksys WMP600N
[code3ncgtwkj]03:07.0 Network controller: Ralink corp. RT2800 802.11n PCI
Subsystem: Linksys Device 0067
Kernel driver in use: rt2800pci
Kernel modules: rt2800pci
[/code3ncgtwkj]
And running Arch x64 with linux 3.0.3 kernel. The adapter is working as AP with hostad 0.7.3.

After starting hostapd the next is printed to dmesg
[code3ncgtwkj]phy0 -> rt2800pci_mcu_status: Error - MCU request failed, no response from hardware[/code3ncgtwkj]
And sometimes wifi dissapears after some time. But this is rare.
How to fix this error?
