How to Safeguard Your Home Network After Giving Wi-Fi Access to a Neighbor

It’s easy to find ourselves in situations where we make hasty decisions, especially when it comes to helping others. Recently, I agreed to let my neighbor’s teenage grandson use our Wi-Fi, under the impression that it would be a harmless gesture. However, after reflecting on my own adolescent internet escapades, I’ve begun to reconsider the implications of this decision.

The Background Story

Not long ago, a young boy around the age of 15 moved in next door with his grandparents. Unfortunately, his grandpa chose not to install internet service in their home. Since I recently upgraded to a high-speed fiber internet connection with an unlimited 50 Mbps upload and download capability, I thought allowing him access would be a generous and neighborly act.

Initially, he even offered to pay for the service, but instead, I requested that he use it responsibly and maintain a clean online environment. As I mulled over the situation, however, I realized I had inadvertently given him access to all of my devices connected to the same network. In my teens, I remember how mischievous we could be online. This revelation set off alarm bells in my head.

The Need for Network Isolation

With the realization that my home network might be vulnerable, I felt compelled to take action. I started researching ways to isolate his access from my primary network. One option that surfaced was wireless isolation—an intriguing concept, but I needed more information about its effectiveness.

Another idea I had was to repurpose a spare router. By hardwiring it to my main connection and setting it up in a location accessible to the kid, I could create a completely separate subnet. This could help safeguard my personal devices from potential mishaps or mischievous behavior. I currently utilize a Netgear Nighthawk R7000 router flash with DD-WRT firmware connected to a Bell HomeHub 3000, so I’m aware of the basics of subnetting but need guidance on implementation.

Seeking Expert Advice

I’m reaching out to the community for insights or suggestions on managing this situation effectively. Have any of you installed a guest network using a secondary router? How do you ensure responsible usage while keeping your essential devices secure?

Your expertise and experiences could be just what I need to navigate this strange blend of neighborly kindness and cybersecurity vigilance. Let’s collaborate to ensure our home networks remain protected, even when extending a helping hand.
