Kevin Nanns / Network Architect
Your tech does weird stuff.I show you what's actually happening.
Full Wi-Fi bars and nothing loads. A video call freezes for one person. Your work laptop behaves differently at home. I use real devices, packet captures, logs, and 15+ years of networking judgment to show you why.
- Packet captures
- Logs and settings
- Controlled tests
- Real devices and gear

Start with what you noticed
You notice the symptom. I follow the evidence.
- 01
Full Wi-Fi bars. Painfully slow internet.
- 02
A fast speed test. One app still crawls.
- 03
The VPN icon is green. You still do not know what it hides.
- 04
A device appears on your router. You have no idea what it is.
What the proof changes
The icon can be accurate and still answer the wrong question.
A signal icon, speed test, or green dashboard only shows what it measured. I put the symptom next to the packet, log, setting, or controlled test that explains it. Then I stop at what the evidence can support.

Hiding Your WiFi Network Doesn't Actually Hide It
That 'hide network' checkbox feels like locking a door. It isn't. Here's what actually happens when you hide your SSID and why it doesn't protect you from anything.

The person behind AdjacentNode
I'm Kevin.
I'm a network architect with more than 15 years in IT. AdjacentNode is where I use that background to investigate the technology everyone already lives with, then show the work instead of asking you to trust the answer.
Networking is my deepest lane. It is not the edge of the channel. It is the foundation that lets me follow everyday technology into the systems underneath it.
