Internet and Network Issues

Common internet and network concerns for Verifone devices.

Use this when a device — or all your devices — can't connect, or has gone offline.

Symptoms

• One or more devices show no network connection
• Devices go offline, either individually or all at once

Most likely cause: an ISP change, a faulty modem/router, an internet outage, or a loose cable connection.

Pick the correct path

1. Recently switched internet providers
2. All devices offline at the same time
3. Some devices offline, others still online

1) Recently switched internet providers

If you've recently switched ISPs, your network communication might be blocked.

1

Contact your ISP

Ask your internet service provider to whitelist the necessary IP ports. This may require collaborating with Verifone or your Merchant Services Provider.

✅ Issue fixed — stop here. ❌ Still not working — continue to escalation below.

2) All devices offline at the same time

1

Check for an outage

Check whether your modem or router is faulty, or whether there's an internet outage. Confirm your network is visible; if it isn't, contact your ISP.

✅ Issue fixed — stop here. ❌ Still not working — continue to escalation below.

3) Some devices offline, others still online

1

Check the router connection

Verify which router the affected devices are connected to, and confirm all cables are securely plugged in.

2

Check the router's lights

Look for flashing green lights on the router. Solid yellow or red lights may mean the router needs a reset.

3

Inspect the cabling

Check the cable connections from the router to the devices, including any Ethernet adapters.

4

Isolate the device

If your site setup permits, test the non-working device at a known-working station to determine whether the cause is the cabling or the device itself.

✅ Issue fixed — stop here. ❌ Still not working — continue to escalation below.

Still not working? Contact the Helpdesk

If none of the above resolves it, contact your Internet Service Provider for connectivity issues, or your Level 1 Helpdesk / Verifone Helpdesk if network configuration changes are needed.
