Securing Your Home Network: Isolating Guest Connections
Recently, I made a decision that I’m starting to reconsider: I allowed the neighbor’s teenager, who recently moved in with his grandparents, to use our Wi-Fi. Initially, it seemed like a kind gesture, especially since his grandfather is hesitant to invest in internet service. However, upon further reflection, I’ve come to realize that granting him this access may not have been the wisest choice.
The Situation
The 15-year-old neighbor offered to compensate me for using our fiber internet, which we installed last year with an unlimited 50 Mbps download and upload speed. Instead of accepting payment, I asked him to be responsible and use the connection appropriately. At that moment, everything felt fine. But as I replayed my own experiences from that age, I remembered the mischief we could cause with technology. It’s a bit unnerving to think about the access I’ve granted him to my home network.
The Dilemma
Now, I find myself in a bit of a predicament. The thought of a teenager having free rein over my devices raises several concerns. I’m particularly worried about security and the potential for negative consequences stemming from this arrangement. Therefore, I need to isolate his connection from the rest of my home network to protect my devices.
Possible Solutions
After doing some research on wireless isolation, I discovered a few methods that could work. One approach is to set up a separate router specifically for his internet access. I have an extra router that could serve this purpose.
Here’s what I’m considering:
-
Create a Separate Network: I could configure the spare router to run on a different subnet than my main network. This would ideally limit his ability to access devices connected to my primary router.
-
Wired Connection: I plan on hardwiring this second router. By placing it in a position where he can easily connect but remain isolated from my primary network, I could enhance security further.
-
Wireless Isolation: Additionally, I’ve read about wireless isolation features that could protect my main devices. This could add another layer of security, ensuring that even within the same network, access is controlled.
My Current Setup
For a clearer picture, here’s my existing network configuration:
- Main Router: Netgear Nighthawk R7000 (AC1900) with DD-WRT firmware (v3.0)
- ISP Device: Bell
