First checks
Check the scope
Try another device on the same home network. Note whether you can join Wi-Fi and whether the problem affects every device. Wi-Fi access alone does not prove the satellite link is working.
Read the provider’s status
Use your provider’s app or official support page to check alerts and service interruptions. Record modem lights or error messages before restarting equipment.
Follow the correct modem guide
Select your provider below for its equipment-specific sequence. Do not factory-reset, splice a proprietary cable or reposition a transmitting antenna as a generic fix.
