2Basic Information
Cellular routers wienet WR-LTE v3 SL are designed for communication in mobile networks using LTE,
HSPA+, UMTS, EDGE or GPRS technology. Data transfer speed is up to 100 Mbit/s (download) and up to
50 Mbit/s (upload). The router is an ideal solution for wireless connection of traffic and security camera
systems, individual computers, LANs, automatic teller machines (ATM), other self-service terminals, lifts
and other machines.
Standard equipment of the router: Two Ethernet 10/100 ports, one USB 2.0 Host port, two binary in-
puts and one output (I/O connector). Two readers for 3 V and 1.8 V SIM cards, memory card reader for
microSD cards – maximum capacity of inserted card can be 64 GB (32 GB in case of SDHC cards).
Optional equipment of the router: The router can be equipped with WiFi module on customer’s request
(it is not possible to add it to the router later in the future). Other possible interfaces are: Three ports
SWITCH, serial line RS232, combined serial line RS232-RS485/422, combined Ethernet and serial lines
with stronger insulation RS232-RS485-ETH. The Router is supplied in a metal casing, based on the re-
quirements of the customer. For details see the router’s Technical manual.
Configuration possibilities: Statistics about the router activities, signal strength, detailed system log,
etc. Creation of VPN tunnels using technologies IPSec, OpenVPN and L2TP for secure communications.
Functions such as DHCP, NAT, NAT-T, DynDNS, NTP, VRRP, control by SMS, backup primary connec-
tion and many other. Automatic check of PPP connection offering an automatic restart feature in case of
connection fail, hardware watchdog monitoring the status of the router. It’s possible to insert Linux
scripts for various actions. Several different configurations for one LTE wireless router and the option to
switch between them (e.g. via SMS, binary input status, etc.). Automatic upgrade configuration and firm-
ware update from server. This allows mass reconfiguration of many routers at one time.
Ways of configuration: Routers can be configured via web browser or Secure Shell (SSH). Configura-
tion via Web Browser is described in this Configuration Manual. Commands and scripts applicable in
configuration via SSH are described in Commands and Scripts for v2 and v3 Routers – Application Note
[1]. The standard and optional equipment and technical parameters of your router can be found in the
User’s Manual of your router. You can use additional software – communication VPN server WIE-Ser-
vice24 [2].
This Configuration Manual describes:
•Configuration of the router item by item according to the web interface (chapters 3 to 6).
•Examples of these typical configurations of the router (chapter 7):
–Access to the Internet from LAN (Local Area Network) via mobile network
–Backed up access to the Internet (from LAN)
–Secure networks interconnection or using VPN (Virtal Private Network)
–Serial Gateway (connection of serial devices to the Internet)

Access to the Web Configuration
Wieland Electric GmbH | BA001039 (Rev. A) | 08/2016 8
3Access to the Web Configuration
Attention!
The cellular router will not operate unless the cellular carrier has been correctly config-
ured and the account activated and provisioned for data communications. For mobile
technology carriers, a SIM card must be inserted into the router. Do not insert the SIM
card when the router is powered up.
You can monitor the status, configuration and administration of the router via the Web interface. To ac-
cess the router over the web interface, enter http://xxx.xxx.xxx.xxx as URL into the browser where
xxx.xxx.xxx.xxx is the router IP address. The router’s default IP address is
192.168.1.1
and only access
via secured
HTTPS
protocol is available. That implies the adress of the router has to be in
https://192.168.1.1 syntax. When accessing for the first time, it will be necessary to install a security cer-
tificate. To prevent the domain disagreement message of your browser, follow the procedure described
in the following subchapter. Configuration may be performed only by the user
root
with initial password
root
.
Example of the web configuration
ATTENTION

Access to the Web Configuration
9 Wieland Electric GmbH | BA001039 (Rev. A) | 08/2016
When you successfully enter login information on the login page, the web interface will be displayed. The
left side of the web interface
displays the menu. You will find links for the Status, Configuration, Custom-
ization and Administration
of the router.
Name and Location displays the router’s name, location and SNMP configuration (see 4.17). These fields
are user-defined for each router.
Attention!
For enhanced security, you should change the default password. If the router’s de-
fault password is set, the menu item
Change password
is highlighted in red.
If the green LED is blinking, you may restore the router to its factory default settings by pressing RST on
the rear panel. The configuration will be restored to the factory defaults and the router will reboot. (The
green LED will be on during the reboot.)
3.1 Preventing the domain disagreement message
Since the domain name in the certificate is the given MAC address of the router, it is necessary to access
the router via this domain name (use dash separators instead of colons). To enable this, add a DNS rec-
ord in your DNS system:
•Edit
/etc/hosts (Linux/Unix OS)
•Edit
C:\WINDOWS\system32\drivers\etc\hosts (Windows OS)
•Configure your own DNS server
To access the router with MAC address 00:11:22:33:44:55 securely, type the address https://00-11-22-33-
44-55 in the web browser. When accessing for the first time, it will be necessary to install a security cer-
tificate.
Note!
If using self signed certificate, the files https_cert and https_key has to be uploaded into
/etc/certs directory of the router
.

signed.
4.9 System Log
In case of any connection problems it is possible to view the system log by pressing the System Log
menu item. Detailed reports from individual applications running in the router are displayed. Use the Save
Log
button to save the system log to a connected computer (the text file with the .log extension will be
saved). The second button –
Save Report – is used for creating detailed report (generates all information
needed by support in one text file in the .txt format – statistical data, routing and process tables, system
log, configuration).
The default length of the system log is 1000 lines. After reaching 1000 lines the new file is created for
storing the system log. After completion of 1000 lines in the second file, the first file is overwritten with
the new one.
Output of the system log is done by the
Syslogd program. It can be started with two options to modify its
behavior. Option "-
S " followed by decimal number sets the maximal number of lines in one log file. Op-
tion "-
R " followed by hostname or IP address enables logging to a remote syslog daemon. (If the remote
syslog deamon is Linux OS, there has to be remote logging enabled (typically running "
syslogd -R "). If it’s
the Windows OS, there has to be syslog server installed, e.g.
Syslog Watcher ). To start syslogd with
these options, the "/etc/init.d/syslog" script can be modified via SSH or lines can be added into
Startup
Script
(accessible in Configuration section ) according to figure.

5.1 LAN Configuration
Select the LAN menu item to enter the network configuration for the Ethernet ports. Primary subi-
tem is intended for the first ETH router’s interface (ETH0),
Secondary is for the second ETH router’s
interface (ETH1).
Tertiary LAN is for the SWITCH (3x Ethernet) or RS232- RS485-ETH expansion port
if installed, it is the ETH2 interface.
Item
Description
DHCP Client
•disabled
– The router does not allow automatic allocation IP address
from a DHCP server in LAN network.
•
enabled
– The router allows automatic allocation IP address from a
DHCP server in LAN network.
IP address
Fixed set IP address of network interface ETH.
Subnet Mask
IP address of Subnet Mask.
Bridged
•no – router is not used as a bridge (default)
•yes – router is used as a bridge
Media type
•Auto-negation – The router automatically sets the best speed and
duplex mode of communication according to the network’s possibil-
ities.
•
100
Mbps Full Duplex
– The router communicates at 100 Mbps, in
the full duplex mode.
•
100
Mbps Half Duplex
– The router communicates at 100 Mbps, in
the half duplex mode.
•
10
Mbps Full Duplex
– The router communicates at 10 Mbps, in
the full duplex mode.
•
10
Mbps Half Duplex
– The router communicates at 10 Mbps, in
the half duplex mode.
PoE PSE
•enabled – The router provides power on the Ethernet cable
•
disabled
– The router does not provide power on the Ethernet cable
(default)
Default Gateway
IP address of router default gateway. If filled in, all packets not fitting
the route table rules would have been sent to this adress.
DNS server
IP address of DNS server of the router. All the DNS queries are for-
warded to this address.
Configuration of the Network Interface
The
Default Gateway and DNS Server items are only used if the DHCP Client item is disabled, and if the
Primary or Secondary LAN is selected by the Backup Routes system as a default route. (The backup
routes selection algorithm is described in section
Backup Routes ). Since FW 5.3.0, Default Gateway and
DNS Server are also supported on bridged interfaces (e.g. eth0 + eth1).
There can be only one active bridge on the router at a time. Only the parameters
DHCP Client, IP address
and
Subnet Mask can be used to configure the bridge. The Primary LAN has the higher priority when
both interfaces (eth0, eth1) are added to the bridge. Other interfaces (wlan0 – wifi) can be added (or de-
leted) to (from) an existing bridge at any time. Moreover, the bridge can be created on demand for such
interfaces but not configured by their respective parameters.
The DHCP server assigns the IP address, default gateway IP address, and IP address of the DNS server to
the connected DHCP clients. If these values are filled-in by the user in the configuration form, they are
preferred.
