Configuration
The LTE daemon checks the network type every few seconds. If it is auto and the modem is currently on the 3G
network, the LTE daemon checks the signal information. If LTE signal is strong enough (RSRP >= -115), it increases the
internal handover counter by 1. If the counter reaches 5, it means the modem is having trouble performing auto
handover. When that happens, the LTE daemon will restart the modem to make sure it goes back to the LTE network. If
the LTE signal disappears before the counter reaches 5, it is reset to 0.
You must use set manual-handover enable to enable this feature.
set apn
FortiWiFi-40F-3G4G (lte-modem) # set apn
<string> please input string value
By default, the APN is not set, which means that the modem can connect to any available network it discovers from its
automatic network scan. If an APN is set, the modem will only connect to a wireless network with the specific APN.
set force-wireless-profile
FortiWiFi-40F-3G4G (lte-modem) # set force-wireless-profile
force-wireless-profile Enter an integer value from <0> to <16>.
When the modem starts a data session, it matches the APN settings, which is either set by the user or from its network
scan, against entries in the wireless profile table. If no matching profile is found, it will not send the data connection
request and reports an error instead.
It is quite possible that multiple matching profiles with the same APN exist in a profile table, while you want to specify a
profile which will not be returned as the matching profile based on our criteria. If you really want to use that profile, you
can specify the profile ID in this configuration.
Keep in mind that if the specified wireless profile does not match the parameters in the data connection request such as
apn, authtype, etc., an error is reported.
This configuration must be used with set apn. Otherwise, it has no effect.
set authtype
FortiWiFi-40F-3G4G (lte-modem) # set authtype
none Username and password not required.
pap Use PAP authentication.
chap Use CHAP authentication.
both Use PAP/CHAP authentication
Sometimes, you get a SIM card for a private network which might require authentication. You can set the authentication
type, and username and password in the configuration. Whether you use PAP or CHAP authentication, it is OK to set
the option to both because the modem knows which algorithm to use.
Once an authentication type is chosen, the hidden username and password options appear, as illustrated below.
