Hi Elizabeth, you currently have no devices directly connected to your Gateway with an ethernet cord. I bet you’d see an immediate improvement using a wired connection. Wi-Fi uses radio frequency (RF) signals that work best for line-of-sight. The layout and construction of your home, physical obstructions, RF interference (generated by computers, electronics, microwave ovens, 2.4 GHz cordless phones, baby monitors, large metal surfaces), and distance from your router or Gateway all impact wireless signal strength, speed, and range. Wireless signals degrade differently based on house construction. The following signal attenuation occurs when passing through walls based on their construction:
• 26 dB through a metal wall
• 13 dB through a concrete wall
• 1 dB through plywood wall
Cox recommends a wired connection for folks in your situation. My last home had tiny rooms and a lot of concrete. I needed to utilize several powerline adapters and a Wi-Fi extender to broadcast the signal successfully throughout my house. -Becky, Cox Support Forums Moderator
