Imagine a world where your energy consumption is no longer a mystery, where you're not just a passive consumer but an active participant in the energy ecosystem. Welcome to the realm of smart metering, a dynamic duo of innovations that brings your energy usage to life and bridges the gap between you and your energy supplier like never before. Let's embark on a journey through the heart of this groundbreaking system, where two interconnected marvels, the Home Area Network, and the Wide Area Network, pave the way for a brighter, more efficient future.

Home Area Network: Where Your Energy Story Begins

Step into the Home Area Network (HAN), an ingenious cornerstone within your abode's walls. Think of it as the beating heart of the smart metering revolution entrusted to the care of your energy supplier. Nestled within this network are the remarkable smart meters, the in-home display acting as your energy interpreter, and the communication hub – your home's energy command center.

Picture this hub as a vibrant energy orchestra conductor orchestrating a symphony of data flows. Like diligent messengers, your smart meters wirelessly transmit vital energy insights to this hub. And like magic, the hub dispatches this treasure trove of information to your in-home display and energy supplier. It's a dance of connectivity that transforms mere data into actionable wisdom.

A cable connects hub SEAP-2001-V to the Electricity meter and wirelessly to the local HAN network for the Gas Meter and the WAN for DDC meter readings.

The GAS meter sends its readings over the HAN to the HUB for forwarding over the LAN to the DCC for onward transmission to the billing company. The IHD picks up the meter readings from the HUB over the HAN for local convenient display for the customer.

But here's the twist: harmony is disrupted if the Home Area Network falters. Smart meters lose their voice, and the in-home display falls silent. The vital conversation between you and your energy supplier stutters. It's a reminder of the intricate ballet that powers this new-age relationship.

Wide Area Network: Where Conversations Transcend Boundaries

As we journey beyond the confines of our homes, we encounter the Wide Area Network (WAN), an expansive realm that bridges gaps and brings the world of smart metering to life on a grand scale. Imagine it as a vast web of communication threads spanning across cities and landscapes, uniting smart meters and energy suppliers in a seamless conversation.

This grandeur exchange occurs over a secure network reminiscent of the technology behind our trusty mobile phones. And at the heart of this exchange lies the communications hub, a master connector between the intimate Home Area Network and the sprawling Wide Area Network. When all is well in this realm, the dialogue between smart meters and suppliers flows effortlessly, enriching both sides with valuable insights.

If you live in a weak 4G signal area, the WAN can fail to connect to the network, and meter readings are not transmitted to the billing companies. You may find an 'aerial extension' from the HUB installed to reach a more reliable or stronger 4G from the WAN connection.

Yet, just as nature has its storms, so does technology. When the Wide Area Network faces turbulence, the symphony of communication falters. Smart meters lose their voice, and the vibrant exchange with suppliers quietens. It's a reminder of the delicate equilibrium that fuels this dynamic conversation.

The Marvel of Evolution: From Third-Party to National Network

In this saga of innovation, we encounter a fascinating evolution in the realm of communications networks. In the early chapters, third-party networks took center stage, enabling the magic of smart meters to touch our lives. Then, a purpose-built national communications network emerged with a flourish, an architectural marvel sculpted by the Data and Communications Company (DCC). This new era promised even greater wonders.

Yet, like all great transformations, the transition wasn't without its challenges. The national network, while potent, wasn't ready when the smart meter wave began. To ensure you could experience the marvels of smart meters, energy suppliers harnessed the power of third-party networks. First-generation smart meters danced to the tune of these networks, sharing their insights with suppliers.

Enter the second generation, donning the cloak of progress. These smart meters seamlessly embraced the purpose-built national network, painting a portrait of connectivity unparalleled in its elegance. But there's a catch: the tale of the SMETS1 meters, their magic bound to a single supplier. When the supplier changes, the magic dims, and the meters are in a "dumb" slumber. Yet fret not for the Data and Communications Company toils to awaken these slumbering sentinels, ensuring compatibility with all suppliers in a symphony of phases.

As we close this chapter, we stand on the precipice of a new dawn in energy management. Smart metering, with its twin enigmas of Home Area Network and Wide Area Network, promises a future where energy is no longer a mystery but a symphony of understanding. It's a dance of data, a connectivity conversation, and an ode to progress. So, embrace the magic, for the journey has only just begun.

VPN by Google One can encrypt and secure your internet traffic by using the Google Virtual Private Network to connect your phone to the internet.

One problem with the Google VPN is that it keeps disconnecting or won't connect. Sometimes it connects, and other times it won't. It is frustrating to have a paid service that just isn't reliable. With all this technology, why can Google make their VPN work properly? We have the fix for that.

Testing

There is a solution, but you can do some testing first to ensure the Google One VPN fix will suit your disconnecting problem.

Firstly

Test the VPN on WiFi only.
Switch off Mobile Data and see if the Use VPN gives you the 'Connected. Your online activity is private.' message.
You will expect to see a static 'VPN is connecting...' and the red failure message 'VPN has disconnected and trying to reconnect VPN...' in a constant loop.

Secondly

Test the VPN on Mobile Data only.
Switch off WiFI and see if the Use VPN gives you the 'Connected. Your online activity is private.' message.
At this point, it gets exciting if you do see the 'Connected. Your online activity is private.' message.
You think the problem may be solved, and the Google VPN now protects your internet.

Well, your VPN is working, but switch back to wifi only again and see the cycle of the VPN not working on wifi but working on mobile data (3G/4G/5G). This indicates the home router is the problem in this instance.

If your VPN works on mobile data but fails to connect when on WiFi, you can be quite confident that the home router is the problem and this solution will work for you.

Router

Most home routers have an additional setting, the web administration interface, often found at http://192.168.1.1 or http://192.168.1.254, but you can often find the router's address on the back or underside of it. Whatever the router's address, you need to log into the router with the username and password to change the settings. Your ISP could help you with this, particularly if they supplied your home router as part of the broadband package.

Settings

If you have a PlusNet router, you can find the setting here: http://192.168.1.254/broadband.htm then press VPN option.

To fix the Google VPN, the router setting you need to change is 'Port Clamping to ON.' If the port clamping is off, switch it on. If it's already on, toggle it off/on. Save the setting and wait. The router may reboot or take a few seconds to reconfigure the port clamping setting you have enabled.

Working

When the router is back online, and you have WiFi, do the testing again. Check if the Google One VPN will successfully connect to your WiFi. You should see the same 'Connected' message on WiFi as on the mobile data.

Is it not working?

Make sure you save the setting in the router. This may take an extra step to confirm the save. Return to the router and check that the port clamping setting is 'ON.'

If you still have VPN disconnects after the fix, try restarting the router to recreate the connection to the internet and kickstart the VPN.

Port Clamping

The solution is to use the port clamping setting in your router. This is what that settings does in the router:

This will set the internet key exchange to UDP port 500 rather than allowing a floating port - a setting sometimes required by older VPN clients to stay connected.
