What is a Wi-Fi health score?
A Wi-Fi health score is a single 0–100 number that summarizes the overall condition of your wireless network at a specific site or access point. Instead of asking your IT team to interpret dozens of radio metrics — signal strength, channel utilization, retry rate, association failures — a health score collapses them into one actionable number that executives, customers, and NOC engineers can all read at a glance.
The four inputs
Most Wi-Fi health scoring engines weight four core dimensions. Coverage measures whether clients can associate cleanly — typically based on RSSI distributions and signal-to-noise ratio (SNR) across the floor. Interference scores how much co-channel or adjacent-channel noise is degrading the RF environment, including neighboring networks and non-Wi-Fi sources. Capacity reflects how heavily loaded each access point is relative to its practical ceiling — client count, airtime utilization, and throughput share all feed in. Reliability captures how often things go wrong: retry rates, auth failures, DHCP timeouts, AP-down events, and WAN unavailability. TekFidelityIQ weights and combines these into a per-AP score and rolls them up to a per-site composite.
How to read the number
A score of 90–100 means the network is performing well with no material issues. 75–89 indicates mild degradation worth monitoring — usually a congested channel or a couple of APs with weaker coverage. 60–74 is a moderate problem zone: clients are likely noticing sluggishness or association issues. Below 60, users are almost certainly complaining and the network needs active attention. Below 40 typically indicates a hardware failure, severe interference event, or misconfiguration. These thresholds aren't universal — a warehouse with 50 barcode scanners has different expectations than a 4K-video education lab — but they give your team and your customers a shared frame of reference without a course in 802.11.
Why a single number helps
The most valuable thing about a health score is what it does for accountability. When a managed-services customer asks 'how is our Wi-Fi?' and you can say 'your site scored 91 this month, up from 83 in May, here's what changed' — that's a conversation that builds trust. It also helps internal NOC teams prioritize: when you're managing 40 sites, a ranked list by health score tells you immediately where to look. TekFidelityIQ surfaces health scores in the NOC dashboard, the customer portal, and the monthly health report PDF so every stakeholder sees the same number.
How to improve a low score
The path to a better score depends on which dimension is dragging it down. Coverage gaps usually mean you need to revisit AP placement or power levels — TekFidelityIQ's RF Intelligence maps show you exactly which APs are the worst coverage offenders. Interference issues often resolve with a channel plan change; the platform's channel utilization view across 2.4, 5, and 6 GHz shows which channels are saturated. Capacity problems mean you're running too many clients per AP or haven't enabled band steering — predictive analytics will show you which APs are consistently over-utilized. Reliability issues usually trace back to a specific AP firmware version, a WAN problem, or a DHCP server under load.
Frequently Asked Questions
- What is a good Wi-Fi health score?
- A score of 85 or above is generally considered healthy. Scores between 70–84 indicate moderate issues worth investigating. Below 70, users are likely noticing performance problems.
- How often is the health score updated?
- TekFidelityIQ updates health scores on the snapshot cadence for your plan — every 24 hours on Trial/Command Core, every 6 hours on Operational Intelligence, and hourly on Enterprise.
- Can I see a health score trend over time?
- Yes. TekFidelityIQ tracks health score history per site and per AP, so you can see how scores change after a firmware update, a channel change, or a capacity expansion.
