Maximizing Internet Speed: A Comprehensive Guide to Connectivity
Written on
Chapter 1: The Importance of Reliable Internet
In today's digital age, having a reliable internet connection is crucial, especially for those of us working from home. A stable and fast connection is as essential as breathing. Without it, participating in virtual meetings or enjoying streaming services becomes nearly impossible, hampering productivity and leisure alike.
"Difficult times require way more hardware than necessary."
Section 1.1: The Challenges of Working from Home
Living in Central London, where roadwork and unforeseen incidents can disrupt internet services, poses unique challenges. As a contractor, I can't afford lengthy offline periods. While tethering from a mobile phone can offer a temporary fix, it only serves my laptop, leaving other devices in my home high and dry.
Internet outages can stem from a variety of issues—floods, fires, equipment theft, or even simple configuration errors. Moreover, bandwidth limitations are a recurring problem. For instance, my building's connection to a nearby exchange, heavily trafficked due to a popular tube station, means that upgrades like fiber optics are perpetually delayed. It’s frustrating to see speeds stuck at a meager 16 Mbps when more modern solutions are available.
Subsection 1.1.1: Preparing for Connectivity Challenges
To tackle these speed limitations, I decided to make the most of my location in Central London, known for its excellent mobile network coverage. Over two weeks, I tested various mobile internet routers and external antennas with sim cards from all major providers, meticulously recording speed and ping results. I also analyzed the annual contract costs versus the speeds offered, weighing the value of potential trade-offs.
After a thorough weekend of testing, I opted for the Netgear M2, which provided impressive speed, long battery life, and a user-friendly configuration interface.
Important Note on Port Forwarding:
Most mobile providers in the UK use CGNAT, which complicates port forwarding from your internal network. Three Mobile is an exception, though it comes with its own set of challenges.
Section 1.2: Exploring Additional Internet Solutions
While the M2 handled 4G/LTE connectivity well, I was fortunate to live in an area with early access to 5G from major providers. I ultimately chose EE for its remarkable stability and speed, despite the higher price tag.
As a long-time Vodafone UK customer, I also acquired another mobile router equipped with my discounted unlimited data sim card.

After integrating multiple connections, I researched and purchased a few essential items, thanks to generous return policies, to optimize my setup.
Testing Various WAN Load Balancers:
I ultimately settled on the TP-Link ER6120 for its gigabit connectivity support and built-in VPN server and client, which I use for both mobile devices and my cloud infrastructure.
To ensure efficient communication within my network, I planned a logical setup that minimizes packet hops. My Raspberry Pi Kubernetes cluster primarily communicates internally, while an Intel NUC serves shared NFS resources. The home WiFi provides internet access, while I frequently access the cluster for various tasks. Guest WiFi allows internet access without compromising internal resources, and certain ports are tunneled through the M2 for port forwarding.
Final Results and Key Takeaways
From a disappointing initial speed of 16 Mbps, I've successfully upgraded to an impressive 400-600 Mbps, allowing seamless work and entertainment without the constant worry of buffering or disconnections. After nearly a year of trials and adjustments, I can't imagine going back to a single provider.
The WAN balancer automatically detects operator-level failures, temporarily disabling affected connections until they’re restored. In Central London, the likelihood of all three major networks failing simultaneously is negligible. If that were ever to happen, I'd be far more concerned about securing food supplies than my internet access.
Practical Tips from My Journey:
- Application Optimized Routing: Keep this feature off to fully utilize the combined potential of your internet connections, despite occasional disruptions with services like FaceTime.
- Dynamic DNS: Use built-in Dynamic DNS clients, as ISPs can change your external IP without notice, especially if utilizing VPN or port forwarding.
- IPv6 Considerations: Many Huawei routers default to making your network IPv6 friendly, which can slow down speeds due to translation delays between IPv4 and IPv6.
By following these insights, you can significantly improve your home internet experience.
