reset your device to factory settings, "hold reset button for 30seconds" after reset use the following
Username -- altai
Password -- wag
IP Address --192.168.1.20
now regarding the no ip issue, if you connect to a different access point you might want to toggle the security functions, toggle from tkip to aes, do not select both, also in the bandwith section make sure its on 20/40mhz, disable isolation and set a static ip, then on your pc input the
ip being used and walla you should be working.
