Thread: Lost wireless all of a sudden. Hardware or software issue?

hi,

surfing internet happily yesterday when of sudden wireless internet stopped working , netbook seems kind of frozen. tried reboot discover cannot turn wireless on keyboard buttons anymore. tried google , searching different forms in vain. gathered diagnosis along way posted below, starting wonder whether hardware or software failure. suspect hardware issue happened out of blue, not sure how check out. ideas?

dmesg output has hints, googling did not give clues going on.

code:

laptop:~$ dmesg | grep rt  [   13.033006] phy0 -> rt2500usb_init_eeprom: error - invalid rt chipset detected.  [   13.033026] phy0 -> rt2x00lib_probe_dev: error - failed allocate device.
