  • Where to put the router if the fiber optic port is inside the wall

    Where to put the router if the fiber optic port is inside the wall

    Although Wi-Fi signals can pass through walls, this may weaken the signals, especially if your home has brick or concrete walls. Putting the router in an unobstructed place, such as near an open doorway, will help the signal travel farther. However, the main reason it's important to do this is because walls and objects slow down the signal, so a central location means less to travel through and a stronger signal for scrolling, clicking and. Compatible router: Verify that your router supports fiber optic input (look for an SFP or WAN port labeled "ONT" or "Fiber"). Ethernet cable: To link the ONT/modem to the router. Very little code (must do) concerning low voltage. Fiber optic cable is typically installed inside a house by following a few steps.
