Card terminals keep disconnecting — what to check before you replace anything

Terminals fail in two ways: they lose connection to the network, or the network loses connection to the payment provider. Both look identical to staff at the bar — the transaction just spins. The fix for each is completely different.

The goal of an assessment is to figure out which one you have before spending on new hardware.

Before booking anything, try this yourself during a quiet moment:

• Stand where the terminal usually sits. Open your phone Wi-Fi settings. What signal bar do you see?
• Try a speed test on your phone in that spot. Is it under 10 Mbps down? That is a coverage problem.
• Ask the terminal provider whether the device is on 4G, Wi-Fi, or Ethernet. Half the time nobody knows.
• Check whether the terminal is on the guest SSID or a staff one. It should not be on guest.

In hospitality specifically, three problems drive the vast majority of card-terminal dropouts: weak Wi-Fi at the till point, guest traffic swamping a flat network at peak times, and a single consumer router being asked to cover a full building.

Any one of those is fixable. The trick is not to guess — measure once and fix the actual cause.

A £199 Business Network Assessment gives you signal readings at each terminal position, a check of your current segmentation, and a written recommendation. If installation work over £1,500 follows, the fee is credited back.
