Setting the LAN configuration

Modem in Always On mode

Having been set in Always On mode, the modem is managing its own connection and

an attached host must use the modem as a point of access to the wireless network.

If an attached terminal intends to establish a PPP session using a serial interface, it

has to launch a dial up session using a #777 dial string. There is no need for

username and password to be entered on the attached terminal side. In this case, a

PPP session is established between the attached terminal and the modem; while

another PPP session between modem and wireless network has already been

established. This is commonly referred to as double PPP. Note that if the wrong dial

string is sent to the modem, the modem would drop the current connection with the

wireless network and defer to On Demand mode.

It is essential that both the modem and the attached terminal be within the same LAN

in order for proper IP communication to take place. In order to verify correct LAN IP

configuration settings on the modem, go to Modem Configuration page and check the

PPP section. By default the IP address of modem is 192.168.0.2 and that of attached

host is 192.168.0.3. These settings are configurable. Verify that attached terminal is

allowed to accept an IP address automatically; if not, set the IP address of modem to

accommodate the IP address of attached terminal so as both would lie within the same

subnet.
