User manual

TP LINK WR703N

The USB on the AR9331 have bugs. if you want use serial console, please the direct serial console on 703N (the /dev/ttyATH0). it's far more stable then USB-serial convertor. you may want add a usb-hub between machine and 703n

Raspberry Pi

The 13 ports USB HUB
  • The default firmware IP address is 192.168.0.100, you can access it by http://192.168.0.100
  • You may need update the address/DNS to your local configuration. DO NOT FORGET your IP address.
  • If Rpi can access internet the cgminer should automatic start
