Mobile WAN
item
in the
Configuration
menu section.
5.3.1 Connection to Mobile Network
If the
Create connection to mobile network
item is selected, the router automatically tries to establish
connection after switching-on. Following items can be set up for every SIM card separately or as two
separate APNs to switch one SIM card between.
Item Description
APN Network identifier (Access Point Name)
Username User name to log into the GSM network
Password Password to log into the GSM network
Authentication Authentication protocol in GSM network
•
PAP or CHAP – authentication method is chosen by router
•
PAP – it is used PAP authentication method
•
CHAP – it is used CHAP authentication method
IP Address IP address of SIM card. The user sets the IP address, only in the case
IP address was assigned of the operator.
Phone Number Telephone number to dial GPRS or CSD connection. Router as a de-
fault telephone number used *99***1 #.
Operator This item can be defined PLNM preferred carrier code
Network type •
Automatic selection – router automatically selects transmission
method according to the availability of transmission technology
• Furthermore, according to the type of router
– it’s also possible to
select a specific method of data transmission (GPRS, UMTS, . . . )
PIN PIN parameter should be set only if it requires a SIM card router. SIM
card is blocked in case of several bad attempts to enter the PIN.
MRU Maximum Receiving Unit – It’s an identifier of maximum size of
packet, which is possible to receive in a given environment. Default
value is 1500 B. Other settings may cause incorrect transmission of
data.
MTU Maximum Transmission Unit – It’s an identifier of max. size of packet,
which is possible to transfer in a given environment. Default value is
1500 B. Other settings may cause incorrect transmission of data.
Mobile WAN connection configuration
Note!
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 de-
fault APN is "internet". The mobile operator defines APN.
•
If the word blank is filled in the APN field, router interprets APN as blank.
