If your TV is buffering, start by checking the connection, restarting the network, and improving the TV’s Wi-Fi signal. If that does not help, test Ethernet if your TV and room setup allow it. When several devices are slow, the problem may be with the router, shared network, or internet provider—not the TV alone.
1. Check the connection and restart your network
Buffering does not always mean your internet plan is too slow. Netflix says a weak or unstable connection can stop video playback, and notes that a device may need an update. Its recommendations are specific to Netflix: 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 recommended stable connection speeds for Netflix’s named quality levels, not guaranteed minimums for every service or every household.
If you can, compare a speed test near the TV with the speed your plan is meant to provide. A strong result on a phone beside the router does not confirm that the TV receives the same connection across the room.
Netflix’s TV buffering guidance recommends restarting the network this way:

Equipment differs, so use the modem or router maker’s instructions if they specify a different restart procedure. Netflix also recommends checking for a device update when playback problems continue. Netflix’s TV buffering guidance explains its troubleshooting steps, and its speed recommendations list the service-specific figures.
2. Improve the TV’s Wi-Fi signal
Try changing the connection conditions before buying networking hardware. Move the router closer to the TV if practical. Keep it in an open spot, off the floor, and away from appliances or other wireless devices that may interfere with the signal. If the TV is tucked inside a cabinet, its wireless connection may also be affected by the surrounding barriers.

Distance, walls and other obstacles, the Wi-Fi frequency band, and simultaneous high-bandwidth activity can all affect performance. If both your router and TV support more than one band, test the other available band from the TV’s actual location. A band with a higher advertised speed is not automatically better through walls or over a longer distance. Pause large downloads or other bandwidth-heavy activity during the test, then compare playback.

3. Test a wired Ethernet connection
If the TV and router can be connected by cable, Ethernet is a useful way to check whether the TV’s Wi-Fi link is the weak point. TCL Support says, “Wired connections are often more stable than Wi-Fi, especially for 4K streaming.” A cable avoids the wireless hop between the TV and router, but it cannot improve an inadequate internet service or fix an upstream outage.
Before getting a cable, check that the TV has a LAN or Ethernet port, that the router has an available port, and that you can route a cable safely between them. No particular cable brand or length is required by the cited guidance; measure the route and confirm the ports on your equipment.

- Only the TV is slow: Check its Wi-Fi signal, connection settings and available device updates. A wired test can help distinguish a weak wireless link from another cause.
- Several devices are slow: Look for shared network congestion, a router problem or an internet-provider issue rather than assuming the TV is at fault.
- The problem persists after these checks: Contact your internet provider to ask about an outage or a network problem. Netflix recommends contacting the ISP when its troubleshooting steps do not resolve the issue.
Router-specific troubleshooting can vary. TP-Link’s slow-internet guidance and Linksys’s mesh-network troubleshooting offer additional checks for their equipment; follow the instructions for the router or mesh system you own.

Best Value
- ✅ [ 2.4GHz only to have WiFi Bridge/Repeater ] This small adapter works with 2.4GHz WiFi to act as a WiFi to LAN bridge (WiFi to Ethernet) or repeater, it can function as WiFi to Wired ( WiFi to Ethernet) at maximum speed of 300Mbps while supporting IEEE 802.11b/g/n. Its small built makes it handy for travelling or easy access in small areas. It requires instatllation, please read carefully the instruction and also check the videos in this listing.
- ✅ [ USB port is for power only ] the adapter's USB port is for power only and does not provide data, so please do not use USB port as data port, also we do not recommend to connect it to TV's USB port since some TVs pick it up as data adapter, unless you go to TV setting and make network connection as Wired. The data port is its Ethernet port and you can use it for LAN or wired data connection.
- ✅ Reeception is up to 50m ( 150ft) in OPEN AREA without obstacles, otherwise there will be signal drop per obstacle such as wall depending on the environement. We recommend to install it close by router, then move it and check the connection strength, it will blink in blue if the connection is weak.
- ✅ Since it can transfer WiFi data to its Ethernet ( LAN ) port therefore there are many applications for this adapter, since some devices do not have internal WiFi adapter (or theirs is faulty) therefore you can use this adapter instead.
- ✅ [ Repeater at 2.4Ghz up to 300Mbps speed ] It can work as WiFi Extender/Repeater as well at 2.4Ghz up to 300Mbps. Please note after installation there is no access to its configuration unless resetting it, after reset it goes back to factory setting and it must be reinstalled and configured as per instruction provided along with it, or you can follow the videos provided in this listing.
