What a 'home network audit' actually checks

A home network audit checks three things: security (default credentials, outdated firmware, network separation), performance (signal strength, device load, channel congestion), and reliability (router age, single points of failure). It's worth knowing exactly what's covered before booking one, rather than a mysterious catch-all service that could mean almost anything depending on who's offering it.
Security checks
Default router credentials still in use, outdated firmware, and whether guest or IoT devices are separated from your main network are all checked, since these are the most common easy entry points into a home network. We also check WiFi encryption standard (whether your router is still on older WPA2 when it supports the more secure WPA3) and review currently and recently connected devices for anything unrecognized.
Performance checks
Signal strength room by room, how many devices are connected and whether the router is straining under the load, and whether coverage gaps exist are measured, not just estimated by feel. We also check for channel congestion from neighboring networks, especially relevant in denser apartment buildings, and confirm actual speeds at the router match what you're paying for.
Reliability checks
We check router age and whether current firmware is actually up to date, look for any single point of failure in the setup (a single access point trying to cover an area that really needs two), and note anything that would leave you without connectivity during a router restart or brief outage without a sensible fallback.
What this doesn't include
A network audit checks the network itself, WiFi, router, connected device security, it doesn't include diagnosing individual device problems (a specific laptop running slow, for instance) unless that's specifically requested alongside it. Worth knowing so expectations match what's actually being assessed.
What you get afterward
A clear picture of what's actually wrong or at risk, and a straightforward list of fixes, rather than a vague 'everything looks fine' with no specifics. We prioritize the findings by actual impact, so you know what's worth fixing immediately versus what's a minor, lower-priority improvement, rather than a flat list with no sense of what matters most.
Key terms
- WPA2 / WPA3
- Wireless encryption standards that protect a WiFi network from unauthorized access. WPA3 is the newer, more secure version, though many routers still ship using the older WPA2.
- IoT devices
- "Internet of Things" devices, everyday connected gadgets like smart plugs, bulbs, and sensors, often with weaker built-in security than a phone or laptop.
Frequently asked questions
What does a home network audit actually check?
It covers three areas: security (default credentials, outdated firmware, network separation), performance (signal strength, device load, channel congestion), and reliability (router age, single points of failure).
What security issues does a network audit look for?
Default router credentials still in use, outdated firmware, whether guest or IoT devices are separated from your main network, the WiFi encryption standard in use, and a review of currently and recently connected devices for anything unrecognized.
Does a network audit also diagnose problems with individual devices?
No, a network audit checks the network itself, WiFi, router, connected device security, it doesn't include diagnosing individual device problems like a specific laptop running slow unless that's specifically requested alongside it.
