Troubleshooting

If the issue persists on one device only

The problem is likely isolated to your computer's network settings or hardware. Try connecting via an Ethernet cable instead of Wi-Fi to determine if the wireless adapter is faulty.

If the issue affects all devices

The problem is likely with your modem, router, or internet service provider. Check that all cables are securely connected and contact your ISP if the gateway lights indicate a line fault.

If you are on a company network, your default gateway may be managed by your IT provider. Avoid changing static IP settings unless instructed by 220 Internet Services.

Resetting your network adapter may remove saved Wi-Fi passwords. Ensure you know your Wi-Fi password before performing a network reset.
