    Weird wireless failure...

    I'm unsure what's gone wrong... I've been using the latest Netbook remix on my EEE 901, and yesterday, wireless networking stopped working.

    I assumed that I must have hit function-F2 and turned off wireless - but after various experiments, I found that even with wireless enabled at this level, things were still amiss.

    The network manager applet says "Disconnected" - and doesn't list any Wi-Fi access points in range - and there are loads - one within a meter. When I right click, both Enable Networking and Enable Wireless (and Enable Notifications) are ticked. If I try to 'connect to hidden wireless network' - and supply my local (non-hidden) network - it asks for the password; waits a while then asks again.

    "lspci" gives the relevant line:

    01:00.0 Network Controller: RaLink RT2800 802.11n PCI

    "rfkill list" gives

    0: eeepc-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    1: eeepc-bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no

    "iwconfig" gives:

    lo no wireless extensions.

    eth0 no wireless extensions

    wlan0 Ralink STA ESSID:"" Nickname:"RT2860STA"
    Mode:Auto Frequency=2.412 GHz Access Point: Not-Associated
    Bit Rate: 1 Mb/s
    RTS thr: off key: off
    Encryption key: off
    Link Quality=10/100 Signal level: 0 dBm Noise level:-98 dBm
    Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
    Tx excessive retries:0 Invalid misc:0 Missed beacon:0

    In my syslog, I've various errors reported, for example:

    kernel: [14.037097] Skipping EBID probe due to cached ebid
    NetworkManager[852]: <info> (wlan0): deactivating device (reason 2).
    NetworkManager[852] <error> [1300448368.575258] [nm-device-wifi.c:1542] nm_device_wifi_set_mode(): (wlan0): error setting mode 2
    NetworkManager[852]: supplicant_interface_acquire: assertion 'mgr_state == NM_SUPPLICANT_MANAGER_STATE_IDLE' failed
    kernel: [14.944349] NICLoadFirmware: MCU is not ready
    kernel: [14.944357] ERROR! NICLoadFirmware failed, status[=0x00000001]
    kernel: [14.944365] rt28xx Initiaized fail!

    Later I get a whole slew of errors from the kernel - mostly mentioning "ERROR! H2M_MAILBOX hold by MCU. command fail" or "ERROR! BBP write R"..." fail"

    Is this a hardware failure, or have I been knobbled by an update? Has anyone else had problems with their EEE PC's wireless?
