Whether you use Xfinity, Spectrum, Verizon Fios, AT&T Fiber or Cox, streaming quality is decided by the last 30 feet of your network.
1. Place the router well
Central, high and in the open. Not in a cabinet, behind the TV or on the floor. Walls and metal cut your speed dramatically.
2. Use 5 GHz for streaming devices
Name your 5 GHz network separately so you can pick it on the TV. Keep 2.4 GHz for smart-home gadgets.
3. Wire what you can
Ethernet to the main TV is the single biggest upgrade. Powerline adapters or MoCA (using your coax) are options when running cable is hard. MoCA is especially useful in homes that already have cable wall outlets.
4. Consider mesh
If the TV is far from the router, a mesh system with a wired backhaul beats any extender.
5. Use your own modem and router
ISP gateways are often weak and have monthly rental fees. Check your ISP's compatible-device list.
6. Update and restart
Update router firmware and reboot it monthly.
7. Check Wi-Fi channel crowding
In apartments, switch to a less crowded channel in the router settings.
