Your home network is more complex than you think. Between smart speakers, security cameras, phones, laptops, and that IoT thermostat you forgot about — there's a lot going on. These guides help you understand what's happening and what to do about it.

Start with a question¶

Not sure where to begin? Pick the question that matches your situation:

What's on my network? — Find every connected device, identify mystery gadgets, and catch unauthorized access.

Is my internet actually slow? — Test speed, latency, and bufferbloat. Find out if the problem is your WiFi, your ISP, or something else.

Am I being watched? — Check for DNS leaks, traffic interception, ARP spoofing, and VPN leaks.

Is my Wi-Fi secure? — Audit encryption, find rogue access points, and lock down your wireless network.

Keep my network healthy — Set up continuous monitoring, baselines, and alerts so you know the moment something changes.

Understand the networking¶

Not sure what ARP spoofing actually is? Wondering why your DNS matters? No networking degree required.

Start with the basics:

• How Networks Work — IP addresses, subnets, routing, LAN vs WAN
• ARP and MAC Addresses — How devices find each other on a local network
• Ports and Services — What port numbers mean and why they matter
• DNS Explained — How your computer turns names into addresses

Security and privacy:

• TLS and Certificates — How HTTPS keeps your traffic private
• WiFi Security — WPA2 vs WPA3, evil twins, and what to watch for
• Firewalls and NAT — What your router's firewall actually does
• VPN Fundamentals — How VPNs work and what can go wrong

Deep dives:

• DHCP How It Works — The protocol that hands out IP addresses
• IPv6 Primer — The next generation of IP addressing
• Device Fingerprinting — How netglance identifies what your devices are
• Network Performance — Latency, jitter, bufferbloat, and why speed tests lie

Making sense of results¶

Ran a scan and not sure what you're looking at?

• Reading Reports — What pass/warn/fail/error mean, how health scores work
• When to Worry — Which findings are urgent vs informational vs noise
• Common Findings — The 20 issues you'll see most often, and whether they matter
• Remediation Playbook — Step-by-step fixes for common issues
