Hi Ike, Could you please attached on the "rfkill list" output when press Fn key? Then we can check the rfkill status change. And, Thinkpad E520 have AMW0 method and I thought acer-wmi query wrong EC register address so your acer-wireless was always soft-blocked. Does it possible kindly help me to find out which register on E520 is mapping to wireless status? Please reference to Carlos's acer_ec.pl tool: http://code.google.com/p/aceracpi/wiki/EmbeddedController Simple use: watch -n 1 perl acer_ec.pl regs Then press your wireless Fn key to monitor which register changed when you press Fn key: e.g. the register at row B0 and column 0A is register 0xBA (0x is used to indicate this is a hexadecimal number). There maybe have other EC register changing when you press key, please do a couple of times and make sure you find out the right one. If we are lucky, we can find out one EC register mapping to your wireless state.
