小弟刷open-wrt到这台AP一半死机，就醒不过来，连不上wifi，
数据线插黄色孔接电脑也ping不到192.168.1.1
查了一下发现90%以上的人都是照着OpenWrt论坛上这段解砖，甚至依此发了不少影片
但是在用tftp回复韧体这段，我按著reset键，LED全闪到，只亮lock跟连接port的灯
甚至开着wireshark搜寻，我不管怎么试都无法用tftp连接我的无线分享器，更别说把
韧体更新回去。
请问各位，我在流程上出了什么问题，有解吗?
TFTP recovery via bootloader for v8,v9,v10,v11,v12
As most other current TP-Link routers this device can be flashed and debricked
without serial access. Basically, the procedure is as follows:
1. Set your PC to use the static IP address 192.168.0.66 (the router will have
192.168.0.86)
2. Put an OpenWrt factory image named: for v8 mr3420v2_tp_recovery.bin or
wr841nv8_tp_recovery.bin (for v8.4); for v9 wr841nv9_tp_recovery.bin; for v10
wr841nv10_tp_recovery.bin; for v11 and v12 wr841nv11_tp_recovery.bin in the
root directory of an TFTP server and start it. For v12 you still need a v12
firmware. Just the filename has to be named as a v11 device!
3. Power on the router while pressing the reset button until the lock LED is
lighting up
4. Wait for the router to reboot
