Wi-Fi keeps dropping in one room: the 5 real causes

Why one room fails while the rest works

Wi-Fi is a radio signal, and thick walls, metal doors, mirrors and steel cabinets absorb or bounce it. The room where the signal drops is usually not far from the router in metres, but it is far in terms of what sits between the two.

That is why a faster internet package from your provider changes nothing. The full speed arrives at the router. The problem is the path from the router to that room.

Cause one: the access point is in the wrong place

The router usually sits wherever the internet cable entered the building: in a corner, inside a cupboard, behind reception. The signal leaves it in every direction, so half of it is wasted on the outside wall.

The fix is not an extender. It is moving the access point to the middle of the space, or adding a second one on a cable at the far end. A wireless extender repeats a signal that is already weak and gives you half of half the speed.

Cause two: channel interference from the neighbours

In a commercial building you may pick up twenty Wi-Fi networks from the offices next door, all crowding onto the same channels. The room next to a neighbour with a strong signal is the one that suffers first.

A router on the wrong channel works perfectly in the morning and stumbles at midday when the office next door fills up. Changing the channel by hand, or using the less crowded 5 GHz band, fixes this case in minutes.

Cause three: the device clings to a distant access point

If you have more than one access point, a laptop may stay connected to the one it started on even after you walk into the other room, because the signal never dropped to zero. You get one bar and constant drops.

This is solved by setting up roaming in the router or controller, or by lowering the transmit power of the far access point so the device lets go of the weak signal and picks up the near one.

Cause four: one network for everyone

If guests, cameras, printers and staff phones all share one network, the meeting room where a meeting starts with ten phones is the first to fall over. There is no weak signal here, just an overloaded access point.

Separating the guest network and capping its speed, and putting cameras and printers on cable, gives the air back to the network your team uses.

Cause five: old equipment or a cheap extender

A seven-year-old router, or an extender bought from the nearest shop, drops connections silently when it gets hot or busy. It looks like a network that is there, but no internet comes through it.

If an extender is what covers that room, unplugging it and testing the room without it shows this immediately.

What you can check yourself in ten minutes

1. 1

   Stand in the room and look at the bars

   One or two bars means a coverage problem. Full bars with drops means congestion or interference.

2. 2

   Try the 5 GHz band

   If the router broadcasts two networks, connect to the one with 5G in its name from inside the room. If it improves, the problem is interference.

3. 3

   Unplug the extender if there is one

   Test the room without it. If it gets better or stays the same, the extender is doing harm, not good.

4. 4

   Count the connected devices

   From the router's page: if more than thirty devices sit on one access point, the problem is congestion, not signal.
