Blank Wimax CPE GUI happen when you switch fro other Wimax modem LOG IN CPE. If experience this and think you have a blank WAN or Broken Firmware your wrong!
In this case I switch from BM622i LOG-IN then I tried to open BM622 and i got Wimax WEB Gui Interface BLANK!!.
How to fix this? Its simple clear the Browser Cache. The same solution for user can't log in and no Error message pop out just like it refresh the page and log in again but no CPE GUI WEB INTERFACE.
After cleared the Cache all back to normal.
You can used Software Optimizer like CCleaner that delete unwanted file and clean your PC.
