We can't clearly explain the issue from here. It might be related to something else. Check if there are other coax outlets in the house that function properly. You'll probably need to locate where the coax enters your home, identify the splitters for each room, and figure out why this one isn't working.
It points somewhere specific but can vary. Often there’s a box on the exterior of your home, though sometimes it’s hidden inside where the internet service provider’s line enters. A splitter is typically present so multiple devices can share the connection, but it might be missing or only intended for a TV with an antenna in the attic. Since we don’t know its destination or if anything is connected, it’s hard to take any action.
Yes, you can purchase a splitter. It typically has a name like "power splitter" or "USB splitter." It generally features multiple output ports for connecting devices.
Is there something comparable on your property? This refers to the splitter you mentioned—on the left side, the looping line represents the ISP connection, which then links to another splitter that distributes signals to various outlets inside the home. Before making any purchases, verify if your current setup matches this configuration.
It's pretty late, so I wasn't able to go outside. But I do have something like that inside one of the rooms.
Start at the main cable entering your residence and identify the splitter location. Usually, the ISP installs the line from the pole or underground point to an exterior box. Occasionally they include a box themselves. The cable proceeds to a grounding block before reaching the main splitter. This splitter might be placed outside or inside based on the configuration. Ideally, there should be only one splitter between the main line and the modem, as the cable modem requires a strong signal. Never allow a splitter with unused ports, as this introduces noise into the system and can disrupt signals for your home and neighboring properties. Unused ports must have terminators installed, use the correct splitter size, or if no splitter is needed, connect directly with a barrel connector, ensuring only the relevant wires are joined to prevent interference. The cable network operates on the same frequency bands as radio, television, cellular, etc., but signals travel through the cable rather than the air, which can lead to interference issues.
