a week before my modem WM66E is still working with great connection, in fact im using it to play dota 2, after my unlisurf promo expired i let my cousin to use it, but he cant even use it coz it's not connecting,the dash board says no sim, not connected and those colors on the light indicator is just flashing and flashing repeatedly. he then try to use the sim on the other modem, E156C model, it's really an old model but it appears that it works better than my modem that time, when i use my modem again on my PC i encountered also the same problem that my cousin had. i really dont know what happened i tried to install and reinstall it, but when i reinstalled it my PC didnt detect my modem, so i used to restore my PC to have again my smart bro app in my desktop, but still nothing showed up, it get worse, because the red light on my modem is just blinking , i tried to use it on laptop windows 8, but with same problem. i hope someone can help me with this problem i really need my modem to work properly again,, thanks in advance (by the way im using windows 7)
