If your phone is reporting Network Not Available or unable to get an IP Address then complete the following to attempt to resolve the issue:
- Ensure that you are using a good, working RJ-45 Ethernet cable
- Visually inspect the cable for any obvious damage
- Do the swap test with a cable that is known to be working
- Ensure that correct ports are being used
- Reseat both ends of Ethernet cable
- Power cycle the phone
- Check the Link Light, if applicable. Even if the Link Light only flashes intermittenly, that still indicates a good connection
If you continue to have issue, then try rebooting your Internet Modem, and Router.
