The information in this page is updated in accordance with firmware version RUT9M_R_00.07.07.2.


Summary

The Network page contains information related to the device's networking. This chapter is an overview of the Network page in RUT901 devices.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

Mobile

The Mobile tab displays information about the mobile connection. The figure below is an example of the Mobile tab: Networking trb2XX manual network v6.png


field name description
SIM card state The current SIM card state. Possible values are:
  • Inserted - SIM card is inserted and ready to be used
  • Not inserted - SIM card is not inserted
  • Unknown - unable to obtain SIM card state value. Possible communication issue between the the device and the modem
Provider Network operator's name
IMSI The IMSI (international mobile subscriber identity) is a unique 15 decimal digit (or less) number used to identify the user of a cellular network
ICCID SIM card's ICCID - a unique serial number used to identify the SIM chip
Operator Network operator's name
Operator state Shows whether the network has currently indicated the registration of the mobile device. Possible values are:
  • Unregistered - not registered to a network and the device is not currently searching for a new operator to register to
  • Registered (home) - registered, home network
  • Searching - not registered to a network, but the device is currently searching for a new operator to register to
  • Network denied - registration to network denied by operator
  • Unknown - operator state is currently unknown
  • Registered (roaming) - registered to network, roaming conditions
Data connection state Indicates whether the device has a mobile data connection or not.
Connection stage Show intermediate stages of mobile connection establishing process.
Network type Mobile network type. Possible values are:
  • 4G: 4G (LTE)
  • 3G: 3G (WCDMA), 3G (HSDPA), 3G (HSUPA), 3G (HSPA), 3G (HSPA+), 3G (DC-HSPA+), 3G (HSDPA+HSUPA), UMTS
  • 2G: 2G (GSM), 2G (GPRS), 2G (EDGE)
  • N/A - not possible to determine at the moment
Carrier Aggregation LTE Advanced Carrier Aggregation, CA, is one of the key techniques used to enable the very high data rates of 4G to be achieved.

By combining more than one carrier together, either in the same or different bands it is possible to increase the bandwidth available and in this way increase the capacity of the link.

Bandwidth Bandwidth describes the maximum data transfer rate of Internet connection.
Connected band Currently used mobile frequency band.
RSSI Received signal strength indicator (RSSI) measured in dBm. Values closer to 0 indicate a better signal strength
Data received Amount of data received through the mobile interface
Data sent Amount of data sent through the mobile interface
Cell ID The ID of the cell that the modem is currently connected to
LAC/TAC
  • LAC The Location Area Code, abbreviated as LAC is the unique number given to each location area within the network. The served area of a cellular radio access network is usually divided into location areas, consisting of one or several radio cells GSM/3G
  • TAC Tracking Area Code is a numerical identifier used in LTE networks to distinguish different tracking areas. A tracking area is a group of cells that share the same identity for tracking and paging purposes. TAC is an essential parameter for the UE to determine its location within the LTE/5G network.
  • Physical cell ID Physical Cell ID is an identification of a cell at physical layer.
    EARFCN In mobile cellular networks, an absolute radio-frequency channel number (ARFCN) is a code that specifies a pair of physical radio carriers used for transmission and reception in a land mobile radio system, one for the uplink signal and one for the downlink signal.
    Mobile country code The Mobile Country Code, abbreviated as MCC, is the code uniquely identifying the home country of a (Glossary:Mobile network operator (MNO|mobile network operator (MNO).
    Mobile network code Mobile Network Code (MNC) is a unique two- or three-digit number used to identify a home Public Land Mobile Network (PLMN) to. MNC is allocated by the national regulator.

    If mobile data limit is set and reached, near Connection column warning mark will appear. E.g.:

    Bands


    bands information
    Name Connected band
    Other signal level measurements Overall signal quality for different network types is defined by different measurements. Short explanations and recommendations are provided below. Click here for more in-depth information or click on one of the links below:
    • 4G
      • RSRP - reference signal received power, measured in dBm. Values closer to 0 indicate better signal strength
      • RSRQ - reference signal received quality, measured in dB. Values closer to 0 indicate a better rate of information transfer
      • SINR - signal-to-interference-plus-noise ratio, measured in dB. Higher values indicate a better rate of information transfer
    • 3G
      • EC/IO - downlink carrier-to-interference ratio. Values range from -20 to 0 (closer to 0 indicates better signal quality/cleanliness)
      • RSCP - received signal code power. Values range from -124 to 0 (closer to 0 indicates better signal stength)
    • 2G
      • RSSI - received signal strength indicator, measured in dBm. Values closer to 0 indicate better signal strength

    LAN

    This tab displays information about the device's local network(s). The figure below is an example of the Network window:

    Networking rutos manual network lan ipv4 v1.png

    lan information
    Name LAN interface name
    Address IP address of the LAN interface
    Netmask Netmask of the LAN interface. In a sense, a netmask specifies the size of a network. In other words, it indicates which part of the IP address denotes the network, and which denotes the device
    dhcp leases
    Interface Interface which leased the address
    Hostname Hostname of a LAN client
    IP Address IP address of a LAN client
    MAC Address MAC address of a LAN client
    Leasetime Remaining Remaining lease time for a DHCP client. Active DHCP lease holders will try to renew their DHCP leases after a half of the lease time passes.
    Static Lease This action will reserve currently assigned IP address for the device in Network -> Interfaces -> Static leases.

    Similarly there is an IPv6 dedicated tab.

    Networking rutos manual network lan ipv6 v1.png

    lan information
    Name LAN interface name
    Address IP address of the LAN interface
    Delegated prefix The delegated prefix is a smaller subnet given to a device to lease IPv6 addresses for its own DHCPv6 clients.
    dhcp leases
    Interface Interface which leased the address
    Hostname Hostname of a LAN client
    Address IP address of a LAN client
    Delegated prefix The delegated prefix is a smaller subnet given to a device to lease IPv6 addresses for its own DHCPv6 clients.
    DUID DHCP unique identifier is used by DHCPv6 to identify device. Similar to MAC that is used by DHCPv4.
    Leasetime Remaining Remaining lease time for a DHCP client. Active DHCP lease holders will try to renew their DHCP leases after a half of the lease time passes.
    Static Lease This action will reserve currently assigned IP address for the device in Network -> Interfaces -> Static leases.

    Firewall

    This tab displays information about the device's firewall. Info is shown of IPv4 and IPv6 traffic. The figure below is an example of the Firewall page tables:
