1. CONFIGURATION OVER WEB BROWSER

Tips for working with the Mobile WAN conﬁguration form:

• If the size is set incorrectly, data transfer may not be succeeded. By setting a lower MTU

it occurs to more frequent fragmentation of data, which means higher overhead and also

the possibility of damage of packet during defragmentation. On the contrary, the higher

value of MTU can cause that the network does not transfer the packet.

• If the IP address ﬁeld is not ﬁlled in, the operator automatically assigns the IP address

when it is establishing the connection. If ﬁlled IP address supplied by the operator, router

accelerate access to the network.

• If the APN ﬁeld is not ﬁlled in, the router automatically selects the APN by the IMSI code

of the SIM card. If the PLMN (operator number format) is not in the list of APN, then

default APN is "internet". The mobile operator deﬁnes APN.

• If the word blank is ﬁlled in the APN ﬁeld, router interprets APN as blank.

ATTENTION:

• If only one SIM card is plugged in the router (router has one slot for a SIM card),

router switches between the APN. Router with two SIM cards switches between

SIM cards.

• Correct PIN must be ﬁlled. For SIM cards with two APN’s there will be the same

PIN for both APN‘s. Otherwise the SIM card can be blocked by false SIM PIN.

Items marked with an asterisk must be ﬁlled in only if this information is required by the op-

erator (carrier).

In case of unsuccessful establishing a connection to mobile network is recommended to

check the accuracy of entered data. Alternatively, try a different authentication method or

network type.

1.13.2 DNS address conﬁguration

The DNS Settings item is designed for easier conﬁguration on the client side. When this

item is set to the value get from opertor router makes an attempt to automatically get an IP

address of the primary and secondary DNS server from the operator. By way of contrast, set

manually option allows you to set IP addresses of Primary DNS servers manually (using the

DNS Server item).

1.13.3 Check connection to mobile network conﬁguration

If the Check Connection item is set to enabled or enabled + bind, chec king the connection

to mobile network is activated. Router will automatically send ping requests to the speciﬁed

domain or IP address (Ping IP Address item) in regular time interval (Ping Interval). In case of

unsuccessful ping, a new one will be sent after ten seconds. If it fails to ping the IP address

of three times in a row, the router terminates the current connection and tries to establish new
