Troubleshooting Common Issues

DNS Not Resolving

Restart Router/Modem: Power cycle your modem by unplugging it for 30 seconds and plugging it back in.

Slow Internet Speed

Check for Device Limitations: Ensure that the devices connected to your network are capable of handling the speeds provided by the ISP.

Test with a Wired Connection: Connect a computer directly to the modem using an Ethernet cable. If the internet works, the issue lies within the router settings.
