    low-voltage troubleshooting

    Wi-Fi access point poor coverage/performance

    Common symptoms: wifi dead spots; ap weak signal; slow wifi in one area; coverage dropped after install

    Stop and call a pro if:

    • Use approved ladders and fall protection for ceiling AP access
    • Do not route low-voltage cable in prohibited pathways

    Step-by-step diagnostic flow

    1. Step 1

      Did performance degrade after a recent AP move, firmware change, or channel plan update?

    2. Step 2

      Can you roll back to the previous known-good AP profile/channel settings?

    3. Step 3

      Is AP uplink stable at expected speed and PoE power class without cycling?

    Possible outcomes

    Configuration/channel regression identified

    high confidence

    Coverage recovered after rollback, indicating a software/channel planning issue.

    Safe next steps
    • Keep known-good profile
    • Reintroduce changes one at a time with validation

    AP uplink or PoE path problem

    high confidence

    Unstable uplink/insufficient PoE causes reduced radio performance or AP throttling.

    Safe next steps
    • Validate cable cert and switch port profile
    • Correct PoE class/power budget
    • Replace suspect patch/cable run

    RF environment issue — perform Wi-Fi survey

    medium confidence

    Healthy AP hardware with poor coverage usually points to placement/interference issues.

    Safe next steps
    • Run predictive or active site survey
    • Adjust AP placement/channel widths
    • Add AP density where needed
