How MWB-4G Works
The MWB-4G combines a powerful wireless bridge and 4G transceiver with
the MWB-AP access point in a separate compact, weatherproof unit. A
wireless bridge acts as a connector between two networks, in this case a
Shore Station Wi-Fi or 4G network which is connected to the Internet and onboard computers. A fixed Ethernet port on the MWB-AP connects a to fixed
computer and an onboard local Wi-Fi network will connect various mobile
devices such as laptops, iPhones & iPads using one Shore Station account.
The MWB-4G integrated bridge will connect to almost any Shore Station Wi-Fi
network with automatic degradation to 4G when no Wi-Fi network is detected.
The MWB-4G may also be manually set to 4G at any time when desired.
Almost any mobile device that’s compatible with Wi-Fi can connect to the
MWB-AP onboard access point. The MWB-4G performs two tasks
simultaneously. In order to connect to the Internet, it employs its transmitter
and antenna to seek available wireless networks. When one is found, it
requests an Internet Protocol (IP) address. (An IP address may be considered
similar to a telephone number in telephone networks, in that it instructs
servers where a web page or an email should be sent in order to reach the
computer.) Once an IP address has been received, the MWB-4G has a
wireless connection to the Internet. At the same time, the MWB-4G monitors
whether any computers are connected to its access point or its Ethernet port.
On connection, it requests an IP address of its own and the MWB-4G serves
an address from its list and the computer then has a connection to the MWB4G. Once these two connections are in place, any data that a device attempts
to send to the Internet is received by the MWB-4G and passed on through the
Shore Station wireless or 4G network to the Internet. Similarly, any data
returned to that device is received by the MWB-4G from the Shore Station
wireless or 4G network and returned through the onboard Access Point.
Installing the MWB-4G
The MWB-4G Marine Wireless & 4G Bridge is easy to install and connect.
First, if installing remote external antenna’s, the antenna site should be
chosen with 360° all around visibility and reasonable height, typically at the
first spreaders or goal post for Yacht installations or on the superstructure
tower of a motor vessel. If using remote mounted antennas, the MWB-4G
should be sited to minimise the antenna cable run. We emphasize the
importance of using well positioned, appropriate high quality, high gain
antennas, coaxial cables, plugs and splitters, all are available from
Pelagic Systems. This is paramount for optimum system performance.
The MWB-AP should be mounted for good local access reception, normally
about the centre of the vessel, usually port or starboard. The system
components are then connected using cables supplied.
Please follow these steps:
1. Mount the MWB-4G unit on a bulkhead or other convenient vertical surface
with the connectors facing downwards. Screw down the two supplied “rubber
duck” antennas to the MWB-4G antenna sockets as labeled. If installing
remote antenna’s, run suitable coaxial cables (such as LMR400) from the
antenna’s to the MWB-4G unit. It is recommend in this instance that the
coaxial cable run is kept to a minimum length, mounting the MWB-4G close to
the coaxial cabin entry. Mount the MWB-AP unit in a suitable position, as
described above.
2. Locate the black waterproof connector at the end of the short 2m Ethernet
power/data cable. Plug that end of the Ethernet power/data cable into
the black connector on the bottom left hand side of the MWB-AP labelled
“PC/POWER LINE IN Data+PoE”, then screw the waterproof connector over
the cable end. Make sure the compression is tight around the washer and
cable, taking care not to over-tighten.
3. Connect the other end of the short Ethernet power/data cable to the port
labelled “Data+PoE OUT” on the Power-over-Ethernet (PoE) Injector.
4. Locate the black waterproof connector at the end of the long 10m (typical)
Ethernet power/data cable. Plug that end of the Ethernet power/data cable
into the black connector on the bottom right hand side of the MWB-AP
labelled “MWB-4G LINE OUT Data+PoE”, then screw the waterproof
connector over the cable end. Make sure the compression nut is tight around
the washer and cable, taking care not to over-tighten.
5. Connect the other end of the long 10m (typical) Ethernet power/data cable
to the MWB-4G labelled “PC Data+PoE”, then screw the waterproof connector
over the cable end. Make sure the compression nut is tight around the washer
and cable, taking care not to over-tighten.
6. Connect your standard Ethernet category 5 (cat5) patch data cable (not
supplied) to the Power Injector port labelled “Data IN” then connect the other
end to your PC Ethernet port.
WARNING! Never connect your PC Ethernet port to any port on the MWB4G, MWB-AP or PoE power supply, other than the Power Injector Port
labelled “Data IN”. Any other connection could result in damage to your PC.
7. Connect the Power Injector to the vessel 12/24v DC system as indicated on
the injector label using the side terminals. Note there are two common “VIN+”
terminals for convenient looped cable power connection.
WARNING! The power injector must be properly grounded! For the DC
power injector, connect a suitably sized ground wire between the ground
terminal on the injector and the power system ground. For an AC power
injector, connect the supplied power plug only to a grounded three-pin outlet.
Configuring a Windows 7 Computer
Note! Although no longer supported, configuring Windows XP is a similar
process to setup for Windows 7 described below.
1. From the Start Menu, select Control Panel, then Network and Internet, then
Network and Internet then Network and Sharing Center.
2. Look for the network connection that uses your computer’s Ethernet port.
This is usually labelled Local Area Connection or LAN.
Note! Although the MWB-4G connects through a wireless network, do not
change the configuration on any Network Connection labelled “Wireless.” The
MWB-4G connects using a computer Ethernet port.
Click on Local Area Connection (or its equivalent) and select Properties from
the pop-up menu.
In the Properties window that opens, select Internet Protocol Version 4
(TCP/IPv4) and click Properties.
3. In the next Properties window, click the round buttons next to obtain an
IP address automatically and Obtain DNS server address automatically. Click
OK to close the Properties windows.
Click OK again to close the LAN Properties window, but don't close the LAN
Status window.
4. Click the Details button on the LAN Status window that is already open.
If the IPv4 IP Address is, your computer has successfully
connected to the MWB-4G.
Configuring the MWB-4G Wi-Fi & 4G Bridge
Once a computer is connected to the MWB-4G, the unit may be configured by
opening a web browser (Internet Explorer, Chrome, FireFox, etc.) and in the
address bar, entering (the IP address of the MWB-4G
wireless bridge). Ignore any website security certificate warning and select
continue to this website.
Enter the default username “mwb4g” and password “mwb4g”.
Once logged in, the computer will load the wireless and interfaces
configuration pages from the MWB-4G. You may find it useful to bookmark
this IP address for future use. On the Interfaces page, the status of the
interfaces is displayed. On the left hand side you see the status flags. On the
page below ether1, lte1 and wlan1 are ENABLED and RUNNING (the “D”
symbol (to disable) is displayed to disable an interface).
Note in the preceding pages the following terms will be referenced:
ether1, Ethernet – the wired connection to the MWB-4G
lte1, LTE – 4G telephone communications
wlan1, Wireless, Wi-Fi shore station communications
At startup, the MWB-4G will automatically attempt to connect to the previously
connected network. If it’s successful and that network is properly configured to
provide Internet access, no changes will be required to the MWB-4G
configuration pages.
Choosing an Shore Station Wi-Fi Network
If a different wireless network is required, for example the vessel’s has moved
to a different port, click wlan1 on the interfaces page.
The details of the wlan1 interface are then displayed. Note that when first
delivered the SSID is set to “NO_STATION” and will require initial selection.
On the interfaces details page click the “scan” button
The scan results are then displayed. Note that the columns can be selected in
order by double clicking the column heading label. In this example “BT Wi-Fi
with-FON” is selected by clicking over the SSID (station name). Then click
“stop” then “close”
Once the SCAN window closes, click “Connect” .
The wireless page then opens, click on wlan1
Note now that the selected SSID is displayed in the SSID field, in this case
“BT Wi-Fi with-FON”. Click on “APPLY” then “OK” to save selection. Note that
if you do not click “APPLY” then “OK” your selection will not be saved!
Now click “LOGOUT” of the MWB4G configuration utility
Now type in any web address such as “” and normally the WiFi station login page is displayed. Once you have completed login, normally
by entering a name and password or paying for use, access to the Internet is
established and other web addresses may be opened in the normal way.
IMPORTANT NOTE: It may not be possible to connect to all of the networks
found with the scan tool. Network operators can block new connections
through the use of encryption, MAC address filtering and other techniques.
Also note that although the MWB-4G may be successfully connected to a
shore station, the shore station may be disconnected from its network, for
example the network operators Internet connection is down. Before calling us
for technical support, please confirm that the network to which you are
attempting to connect is freely available for your use and operational.
Using Encryption Keys
Some wireless networks use encryption to prevent unauthorized users from
connecting to their access points. In order to connect to one of these
networks, first obtain an encryption “key”, a code that identifies an authorized
user by contacting the service provider or using information provided by the
service provider. For obvious reasons, most public Wi-Fi networks don’t use
encryption. If you should need to connect to an encrypted network, enter an
encryption key into the MWB-4G by selecting the “WIRELESS” page and click
security profiles
In security profiles click “ADD NEW” to add a new security profile.
Choose the security method and authentication type required by the selected
network, then enter details in the fields below. Once the security details are
entered name the profile in the name box highlighted then click “APPLY” then
“OK” when you are satisfied with the details. The example below is to set
WPA & WPA2 security keys.
The Wireless page then displays the new security profile available on the
To select the security profile click on “INTERFACES” then “wlan1”
Then click on the security profile popup list arrow and click the new “profile1”
security settings. Once “profile1” is selected then click “APPLY” then “OK”.
The advantage of using named profiles is that several may be saved and reapplied when communicating with different Wi-Fi Shore Stations without the
need to re-enter the details on each occasion.
Manually Selecting 4G Communications Mode
The MWB4G is preset on delivery for a Vodafone UK contract account, if you
require a different network operator or account type see “Selecting a 4G
Communications Network” below. If a Vodafone UK contract SIM card is not
installed into the SIM port (switch off power to check!) also see “Selecting a
4G Communications Network” below.
The MWB4G will normally select a Wi-Fi Shore Station when available in
preference to 4G communications. However, it may be appropriate to
manually connect using 4G communications because the Wi-Fi Shore station
is slow or the signal is poor for example. To select 4G communication select
the “INTERFACES” page and click the “D” button (disable) on the left hand
side of the “wlan1” line. Note on the screen shot below currently next to the
“D” button the “wlan1” status is “R” (running).
Now in the second column wlan1 status has changed to “X” (stopped) and the
button on the left hand side has changed to “E” (Enable). Now that wlan1 is
manually stopped MWB-4G communication switches to 4G and searches for
the 4G network matching the installed SIM card and automatically connects
using the 4G (LTE) configuration set.
Logout from the MWB-4G. Note it may take some minutes for the 4G network
to open a connection to the MWB-4G, once this is established then the
Internet may be accessed in the normal way. To revert to Wi-Fi Shore Station
communications simply open the page below again and click “E” on the wlan1
line and the status changes to “R” (Running).
Selecting a 4G Communications Network
If when arriving in a new area a different 4G telephone network is required, as
an example, because your currently configured 4G network operator is not
available, the MWB-4G will need to be configured for the alternative 4G
network. By default, as delivered, the MWB-4G is configured to connect with
the Vodafone UK network. To scan for a suitable 4G network, see SCANNING
FOR A 4G COMMUNICATIONS NETWORK below. Once a suitable 4G
network operator is identified for the location, first a 4G enabled SIM card
must be purchased if not already at hand. To change SIM cards SWITCH
OFF POWER to the MWB-4G.
WARNING! Never eject or insert a SIM card with the MWB-4G powered
ON. Always SWITCH OFF power to the MWB-4G before ejecting or inserting
Unscrew the SIM port cover, the current SIM card will be seen in the centre
slot. Gently push the SIM card edge into the port and then release. Normally a
click is heard as the SIM card is partially ejected. Carefully remove the SIM
card and store. Insert the replacement SIM card by gently pushing home into
the SIM port with the same orientation as previously (orientation as label
immediately above the socket). Normally a click is heard when the SIM card
locks into the socket. Screw down the SIM port cover and switch on power.
Now login to the MWB-4G configuration browser and on the interfaces page
click lte1.
The 4G configuration page then opens. As delivered the MWB-4G is
configured for contract Vodafone UK. Other 4G network operators require
different settings. We recommend that the network operator provides these
settings in writing either by message or taken from the operator’s web page. If
these setting are not correct, the network operators gateway will not connect
the MWB-4G. After entering the settings, click APPLY then OK to close the
Here is a current list of settings for different 4G UK network operators (all
lower case). They are typically for 4G Data contract accounts. Other accounts
have different settings.

Note these settings are subject to change without notice and should be
confirmed by the 4G network operator on each occasion for the account type.
Logout from the MWB-4G configuration browser. It may take some minutes for
the chosen 4G operator to connect the MWB-4G to the network. Once
connected the Internet may be accessed in the normal way.
Scanning for a 4G Communications Network
The MWB-4G can scan for suitable 4G Networks if it is unknown which 4G
networks are available in the vessel location. Note that the MWB-4G will not
scan while locked onto a 4G network. To scan for 4G networks, first the MWB4G must be unlocked from any 4G networks.
If a 4G scan is required because 4G coverage is lost, the MWB-4G will
probably already be unlocked. This can be checked as described immediately
below then a 4G scan run without further action.
To determine if the MWB-4G is locked onto a 4G network the lte1 status flag
will be set to “R” (running) when locked, see “Manually Selecting 4G
Communications Mode” above for details. To unlock the MWB-4G, either the
SIM card may be replaced leaving the configuration unchanged (Power down
MWB-4G first!) or change the configuration with the same SIM card. The
objective is to ensure the installed SIM card and configuration does NOT
match to ensure the MWB-4G is unlocked from any 4G Network.
The example below changes the 4G configuration page with the same
Vodafone 4G SIM card to ensure the MWB-4G is unlocked from any 4G
First open the MWB-4G configuration browser and on the interfaces page
click lte1 as above. Then on the 4G configuration page in this example the
configuration is changed for the “EE” 4G Network. i.e. APN: “everywhere”,
User & Password left blank. Then click APPLY then OK to save the change.
The Utility Browser then returns to the interfaces page, click lte1 once more.
The 4G configuration page display shows the changes, note User & Password
are null fields.
Now click SCAN. The scanning may take 1-3 minutes. The results are then
displayed, see example below. Here we see that “Vodafone UK” and “EE” 4G
networks are available at the vessel location. The strength of the Vodafone
UK signal “-55dBm” is also displayed as currently in this example we have a
Vodafone 4G SIM card installed in the SIM port. Note “Evolved 3G” is the
correct term for Networks using the industry abbreviation “4G”.
Once the 4G Network is identified by scanning click “STOP” then “CLOSE”
then install the correct SIM card and set the 4G configuration as described in
“Selecting a 4G Communications Network” above. ALWAYS REMEMBER TO
Using the MWB-AP Onboard Access Point
The MWB-AP (access point) comes preconfigured and should not require
initial setup. To connect to the MWB-AP from a mobile wireless device
onboard, simply find the network “Pelagic-Systems-2GHz” or “PelagicSystems-5GHz” in your list of available Wi-Fi networks, and choose Connect.
When asked for the WPA Key, enter the default key “mwbaccess” (use lower
case, WPA & WPA2 keys are by default the same). To customize the MWBAP access point, open the IP address from your browser,
which will open the configuration pages. Login entering “mwbaccess”, with
password “mwbaccess”.
To view the access point details, click “wlan1” on the main wireless display.
Access Point details are then displayed
Normally, these details may be left unaltered. To change the access point
name, click the SSID field
Then enter the required SSID. To save the change click “APPLY” then “OK”.
To change the security keys, click “WIRELESS” on the left hand side, then
click the “SECURITY PROFILES” tab
Then click “ADD NEW”
Enter the required WPA and WPA2 security fields, the default name is set as
“profile1”, this may also be changed as required, then click “APPLY” and “OK”
to save.
Now the second security profile is displayed “profile1”
To select security profile “profile1” click wireless on the left hand side then
click wlan1
The details page is then displayed. Click on the “SECURITY PROFILE” popdown triangle in the “SECURITY PROFILE” field and now “default” and
“profile1” is available for selection. To select “profile1” click “profile1” then click
“APPLY” then “OK” to save the security profile.
When modifying the MWB-AP SSID and/or the security profile the unit should
be power cycled after the changes have been made, first logging out, by
switching the power supply OFF then after a short delay (~30s) switch back
Normally no other changes to the MWB-AP will be required for use.

If, after following the instructions in this Guide and cannot connect to the
Internet, please follow these steps:
1. Check your computer’s IP address.
For a Windows XP/7 computer, go to the Start Menu, choose Control Panel,
then Network Connections, and right-click on Local Area Connection. Choose
Status and then click the Support tab. The IP address will be listed on the
second line and should have the form 192.168.88.XXX
Using Windows Vista, go to the Start Menu, right-click Network, then choose
Properties. In the Network and Sharing Centre, click on Local Area
Connection > View Status, then click Details and look for IPv4 Address.
On a Macintosh computer, go to the Apple menu, choose System
Preferences, then Network. Select Built-In Ethernet and click the TCP/IP tab,
where the IP address will be listed. Your computer should have an IP address
of the form 192.168.88.XXX. If there is no IP address or have a different one,
repeat the procedure in this Guide for setting up your computer to receive an
IP address, and follow Step 2 to confirm that you are connected to the MWB4G.
2. Check that the computer is connected to the MWB-4G. Begin by making
sure that all Ethernet cables and power connections are plugged in tightly and
screwed down. From the computer, open a web browser and enter the IP
address in the address bar. If the MWB-4G access point
login page opens, your PC is connected to the MWB-4G access point. Then,
again using a web browser enter the IP address in the
address bar. If the MWB-4G bridge login page opens, your PC is connected to
the MWB-4G bridge. If not, re-check all connections.
3. Confirm the MWB-4G is connected to a Shore Station Wi-Fi or 4G network.
Login to address and with the utility browser click interfaces. If
connecting to a Wi-Fi Shore Station, check the status flag is set to “R”
(running). If the “R” status flag is set click wlan1 and check the SSID is set to
the expected Shore Wi-Fi Station. Note a scan may be re-run and a Shore
Station selected at this point as previously described. Also note that Wi-Fi
Shore Station operators normally require either login or payment even if the
MWB-4G is connected. To check, enter any address in your Browser e.g.
“” and if login is required the operators page will open. To
confirm a 4G network connection, on the same page check first the wlan1
status flag is set to “X” (stopped). Note the MWB-4G will attempt to connect to
any Wi-Fi Shore Station if wlan1 is running. Check the lte1 status flag is set to
“R”, then click lte1. The lte1 configuration page then opens, click the “info”
button. Check the 4G operator is as expected and the signal strength is
normal. Note if there is no operator a scan may be run to determine available
4G networks and the required SIM card installed.
4. Check again the MWB-4G has an operational connection. Click the
connected PC windows key then settings and select Network Connections.
The Network Connections page opens and a Local Area Connection is
displayed. Click it and the details should be displayed in the left hand column,
for example IP Address: 192.168.88.XXX, Subnet Mask,
Assigned by DHCP. If not go back to “Configuring your Windows 7 Computer”
above. (This is a repeated variation of test 1 above)
5. More generally, confirm that the Wi-Fi or 4G network to which you are
connected is actually available for service. There are many reasons a Wi-Fi
network may be unavailable, even if it appears to allow open connections.
Some private access points are set with filters that only allow traffic to pass
through to pre-approved computers. Some access points are set up with
authentication pages that load slowly or don’t load at all. Some access points
are simply so overloaded that they will not pass traffic to a new client, even
though they allow new clients to connect. If you aren’t sure whether a
particular Wi-Fi network is available, try connecting to a different network. If
you can successfully connect to the Internet through a different network, the
original network you were trying to connect to is probably unavailable. Similar
issues can arise with connection to 4G networks, although not as frequently.
In particular, a 4G network may be “down” in which case normally the MWB4G will not be locked to the network. Check the lte1 status flag is “R” as
described above “Manually Selecting 4G Communications Mode”. If the
Status flag is not set “R” then scan for alternative 4G Networks as described
in “Scanning for a 4G Communications Network”.
