How to access the ADSL modem control panel?

Question

Network administration

Hello. The situation is this: there is a Zyxel P660 RU3 ADSL modem with IP 192.168.1.1, network computers also have addresses 192.168.1.x.
This modem distributes the Internet (through a 5-port hub), everything works. Only one "but" - I can not access the admin panel. Even with a direct connection, bypassing the switch. The IP addresses on the computer are registered statically, the gateway and DNS server specify the same 192.168.1.1.
The modem itself is pinged, scanned with nmap, it can be seen that only port 80 is open, but there is no web interface. You can't reach through telnet either. Where am I dumb?
