wgw1002g gsm gateway web interface not working

Hello!
I have a wgw1002g gsm gateway, but I can't access the web interface. I tried to reset it, but it's not working. I can ping it on the default ip, and I can cannect via ssh, but I also cannot login with the default creditials on ssh, but the web interface is not working. What can be the problem?
