Then restart your network equipment, improve the TV’s Wi-Fi connection, or test Ethernet. If other devices are slow too, the cause may be your home network or internet provider rather than the TV.
1. Check the connection, then restart the TV network
A buffering stream can point to a weak or unstable connection, but the TV or its software may also be involved. Netflix recommends checking your connection against its speed guidance: 3 Mbps or higher for HD (720p), 5 Mbps or higher for Full HD (1080p), and 15 Mbps or higher for UHD (4K). These are Netflix recommendations for those quality levels, not guaranteed minimums for every service or a promise that several simultaneous streams will work.

If the connection seems adequate, restart the equipment before changing settings. Netflix’s TV buffering guidance recommends turning off the TV, unplugging the modem and router for 30 seconds, reconnecting them, waiting for their indicator lights to stabilize, and testing again. Equipment differs, so follow its own restart instructions if they specify another sequence.

2. Improve the TV’s Wi-Fi signal
Wi-Fi performance at the TV depends on more than the speed on your internet plan. Distance from the router, walls and other barriers, the frequency band in use, and other devices’ high-bandwidth activity can all affect the connection. Google’s Nest Wifi guidance describes these factors and recommends checking placement and network conditions.
- Move the router closer to the TV if practical.
- Place the router in an open spot, elevated rather than on the floor, and away from appliances or other wireless devices.
- If both the router and TV support multiple Wi-Fi bands, try the other supported band and compare playback from the TV’s usual location. A band with a higher nominal speed is not necessarily better through walls or across a longer distance.
- Pause or reduce demanding downloads and streams on other devices while troubleshooting.
Make one change at a time and test the same stream in the same room. That makes it easier to tell whether placement, interference or network activity was affecting the TV.

3. Test Ethernet if you can run a cable
A wired connection removes the Wi-Fi hop between the TV and router, which can help when wireless coverage is weak or inconsistent. TCL Support says, “Wired connections are often more stable than Wi-Fi, especially for 4K streaming.” Its instructions apply to the covered TCL Google TV setup, not every television model. TCL’s connection guide shows how to connect a compatible TV’s LAN port to a router.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problems- Check that the TV has a LAN or Ethernet port and that you can route a cable safely to the router.
- Connect the cable to the TV and an available router port.
- Use the TV’s network settings to select the wired connection if it does not switch automatically; menu labels vary by model.
- Play the same content again and compare whether buffering or interruptions improve.
Ethernet can make the link from the TV to the router more stable, but it cannot increase the speed supplied by an inadequate internet plan or resolve an outage upstream. Measure the route and confirm the ports before buying a cable; no particular brand, category or length is established as necessary here.

When the TV is not the only device affected
If phones, computers or other connected devices are also slow, look beyond the TV. Shared network activity, router conditions or an internet-provider problem may be responsible. Google’s Nest Wifi troubleshooting guidance covers network load and Wi-Fi conditions; router-specific steps may differ. TP-Link also provides general router troubleshooting for slow internet.
If only the TV struggles, focus on its signal, connection settings and software. If Netflix playback still buffers after its recommended checks, Netflix advises contacting your internet service provider to investigate the connection. Netflix’s troubleshooting page lays out that escalation. Linksys has additional steps for users of its mesh systems, but they are specific to that equipment: Linksys mesh Wi-Fi troubleshooting.
