tessel2 is fantastic，I like it very much!
but，I found something strange。
use ‘t2 wifi -n ssid ’
device connect to my Router which wifi without password
I can PING my TESSEL IP ,it is wonderful!
use ‘t2 wifi -n ssid -p pwd’
device connect to my Router which wifi has wpa2 password
I found that I can not PING my TESSEL device
I was surprised to find out when use t2 command (t2 list or t2 wifi ),PING is up to success.
if stop PING about 15s,The same thing happened，I need to use t2 command help me to PING my TESSEL device!
