Wireless problems we solve
Enterprise Wi-Fi problems, explained by engineers.
Technical answers to the wireless problems network engineers, infrastructure teams and IT leadership actually escalate — what the symptoms mean, what you can check yourself, and when measurement by a wireless specialist is the only way forward.
NetRobin is a vendor-neutral enterprise wireless consulting firm focused exclusively on wireless engineering. These guides are written for the people who own the problem: network engineers and architects, IT managers and directors, infrastructure and operations leadership, and the VAR and MSP engineers who support them.
Each guide answers the technical question first. Where the problem genuinely needs on-site measurement — a survey, spectrum analysis, over-the-air packet capture, a controller and configuration review, or an independent second opinion — the guide says so and explains what that work should measure and produce.
Technical guides
Slow Wi-Fi with strong signal
Why is Wi-Fi slow even though signal strength is good?
Strong RSSI only proves a client can hear an AP. Throughput is governed by SNR, airtime, retries, channel utilization and PHY rate selection.
Read the guideWarehouse scanner disconnects
Why do warehouse scanners lose connection while roaming?
Scanner and AGV drops in distribution centres are usually roaming, cell-edge and racking-related RF problems rather than coverage shortfalls.
Read the guideRoaming problems & sticky clients
Why are clients sticking to an access point instead of roaming?
The client decides when to roam. Infrastructure can only influence that decision through cell design, power, data rates and 802.11k/v/r assistance.
Read the guideRF & non-Wi-Fi interference
How do I know whether interference is Wi-Fi or non-Wi-Fi, and how do I find it?
Wi-Fi tools see Wi-Fi. Distinguishing contention from non-Wi-Fi energy requires a spectrum analyzer measuring raw RF, not frames.
Read the guideHigh channel utilization & CCI
Why is channel utilization high, and what is co-channel interference?
Airtime is shared and half-duplex. High utilization usually reflects channel reuse, channel width, legacy rates and overlap — not user demand.
Read the guideCoverage gaps & dead zones
Why do we have Wi-Fi dead zones, and how are they properly identified?
Real coverage is measured, not predicted. Gaps usually come from unvalidated designs, changed buildings and client transmit power asymmetry.
Read the guideVoice & real-time application issues
Why do Wi-Fi voice calls drop or degrade when users walk between access points?
Voice, video and real-time control tolerate far less loss, jitter and roam latency than data, so they fail on designs that look healthy.
Read the guideToo many access points
Do I have too many access points?
Over-dense deployments create co-channel interference, ping-ponging clients and wasted airtime. Density should follow capacity, not floor area.
Read the guideWi-Fi 7 / 6 GHz readiness
Is my network ready for Wi-Fi 7 and 6 GHz?
6 GHz changes propagation, channel planning and power rules; Wi-Fi 7 readiness is as much a wired, power and client question as an RF one.
Read the guidePost-deployment validation
How do I validate a Wi-Fi design after deployment?
Validation proves the installed network meets documented coverage, capacity, roaming and application criteria — before users find out that it does not.
Read the guideChoosing the right survey type
Do I need a passive survey, active survey, AP-on-a-Stick survey or validation survey?
Survey type follows the question you need answered — what the RF is, what a client experiences, what a design predicts, or whether a placement works.
Read the guideWarehouse & distribution centre Wi-Fi design
How should Wi-Fi be designed for a warehouse or distribution center?
Warehouse Wi-Fi is a roaming and airtime design problem, not a coverage-map exercise. Racking, ceiling height, antenna choice and client capability drive the outcome.
Read the guideSenior living Wi-Fi design
How should Wi-Fi be designed for assisted living and senior living communities?
Senior living is a residential design problem at community scale: in-apartment coverage, campus-wide staff mobility and shared spaces, on infrastructure often sized years ago.
Read the guideIndoor location, wayfinding & asset tracking
How can wireless infrastructure support indoor location, wayfinding and asset tracking?
Location accuracy depends on AP density, placement geometry and the underlying technology — Wi-Fi, BLE, UWB or RFID. A network designed only for coverage rarely locates well.
Read the guideWi-Fi and the senior living resident experience
Can poor Wi-Fi affect the senior living resident experience?
For residents, the network is part of home: video calls with family, streaming, tablets and smart TVs. Weak in-apartment connectivity becomes a daily experience issue.
