Common problems

What these jobs usually need

The wireless problems we are called for most, and how we handle them

Dead spots

Rooms with no signal at all

Signal mapped room by room, then APs placed where the walls actually block.

Calls dropping

Wi-Fi calls cut out when moving

Roaming tuned with one SSID and proper handover, so you can walk and talk.

Slow but connected

Full bars but nothing loads

Channel congestion measured. Most slow Wi-Fi is a crowded channel, not the plan.

Warehouse scanners

Handhelds losing connection between aisles

Industrial APs surveyed for racking and ceiling height, then roaming tuned.

Guest access

Visitors on the same network as the office

A separate guest SSID, isolated, bandwidth-limited and access controlled.

Neighbours on the Wi-Fi

Unknown devices using your connection

Device list audited, unknown clients blocked and encryption strengthened.

Outdoor areas

Yard or terrace with no coverage

Weatherproof outdoor APs placed and cabled for the areas you actually use.

Too many APs

APs fighting each other

Channel plan and power levels set so the APs cooperate instead of interfering.
