Today's blog will serve as a quick set up guide for the Mikrotik LHG 4G kit.
We covered this product and general 4G theory in much greater detail a couple of weeks back.
If you missed the original post then be sure to check it out here:
We will be discussing how to quickly get your 4G router up and running. The process is very straightforward as most of it is automatically done for you.
All you will need (other than what is included in the kit) is a suitable SIM card. Make sure you get a Data only SIM unless you are going with EE, in which case a normal SIM works just fine.
Once you have acquired a suitable SIM card, you can get started.
Remove everything from your LHG 4G box, you should have the following:
- LHG 4G kit
- 24V power adapter
- PoE injector
- 2x Metal rings
Firstly you will need to put the device together physically:
- Begin by clicking the two legs to the main modem body
- Now attach the central modem you have assembled to the main dish
- Secure the two additional legs to the dish body with the screws supplied
- Now open the service hatch on the modem, you should see a SIM slot next to the LAN port
- Insert your SIM with the chip facing upwards (be sure not to press it in too far)
Next, you will need to power up your device:
To power your LHG, you can either use the supplied injector or any standard PoE switch.
When using the supplied injector, you will need to pair it with the supplied PSU. Connect your PSU to the DC input on the injector.
The female LAN output on the other side will run to your LHG kit; this will carry data and power up to a distance of 90-100m over Ethernet.
- After powering up your LHG, connect your laptop to the LAN on the injector or if using a switch then connect directly into said switch
- Open up a web browser on your laptop and type in 192.168.88.1, you should see be presented with the below
- You will usually be automatically logged in but if you need to then the username is 'admin' with no password
- After login, you should be directed to the 'Quickset' page – if not then select 'Quickset' from the top options
- On the Quickset menu, you should see an active graph with an RSSI reading under 'Status'; this means you have a successful connection
*Note that on my example image I do not have a SIM card installed so I have no graph showing*
- If you have used an EE SIM card then there is an additional step, see below.
- Make sure to click the 'Check for updates' button to automatically update your unit to the latest stable firmware.
- That's all there is to it, now any device you plug into the injector or switch should be able to gain Internet access.
*Additional EE step: If using an EE SIM card then you will need to locate the setting 'APN' which is found in the top left of the quickset menu.
By default, the text field will contain the word 'internet', you need to delete this and replace it with 'everywhere' – now click 'Apply settings' in the bottom right.*
After this, you should see the graph with RSSI reading as mentioned in the configuration steps, be sure to check for updates to make sure you have the latest security protocols.
Congratulations, your 4G router should now be fully up and running!
The last step is to fine-tune where your dish is pointing. The easiest way to achieve this is to use the RSSI reading on the graph found in the Quickset menu.
Simply move your dish around in different directions until you achieve the lowest possible RSSI reading (technically highest as it is measured as a negative).
Anything -80 RSSI or above is a usable signal but an ideal connection is any reading -60 RSSI or higher (-40 RSSI is about as good as you can get in real-life conditions).
While what we have covered today is very basic, it should allow you to get online and provide a stable internet connection for your requirements.
There are much deeper settings that can be used within the RouterOS but we won't cover them today, if you're interested in taking a look then check out 'WebFig' in the web browser menu.
See below image from WebFig menu which is where you can reboot the device from a web browser if required.
