WiFi Dead Zones: What to Check Before Buying More Equipment

Tech Vision3 min read

A video call drops upstairs, but everything works beside the router. Buying a faster internet plan may not solve that. First, work out whether the problem is the connection coming into your building or the WiFi carrying it around the rooms.

Start with a simple comparison

Try the same device near the router and in the problem room. Note what changes: connection speed, call quality, or whether the network disappears. If you can safely test a computer connected by Ethernet, compare that too. A good wired connection with poor upstairs WiFi points toward a coverage problem. Poor results everywhere deserve a check of the internet service and router first.

Map the places you actually use

Write down the rooms that matter: the home office, TV room, kitchen, bedrooms and patio. Walls, floors and equipment placement affect coverage. A router hidden inside a cabinet is not a coverage plan. For a business, include staff devices and the areas customers use, rather than judging the network only from the front desk.

Plan access points instead of collecting extenders

Access points give devices another place to connect. Where cable routes allow, a wired connection back to the network removes the need for an access point to rely on a wireless link for its connection. Wireless mesh can be useful when cabling is impractical, but it still needs thoughtful placement and a dependable signal between devices.

Adding more hardware without checking placement and interference can leave the original problem unresolved. Ubiquiti's guidance addresses signal strength, interference and access-point placement; the right settings depend on the building and devices, not a universal “maximum speed” preset.

Test the result, room by room

  • Repeat a video call where it used to fail.
  • Walk between rooms while using the connection.
  • Check streaming, speakers and other everyday devices.
  • Keep a record of cable labels and equipment locations.

For Long Island homes and businesses, Tech Vision can assess WiFi coverage and cabling before recommending equipment. Request a walkthrough and tell us which rooms are giving you trouble.
