Ethernet vs Wi-Fi for IPTV: does it really make that big a difference?

My router is in the living room about 4 metres from the TV. The Wi-Fi signal shows full bars on the TV. Do I really need to bother running an Ethernet cable? People keep saying Ethernet is better but is there actually a noticeable difference at short range?
 
Yes, there is a real difference even at close range. Full Wi-Fi bars tell you signal strength — they do not tell you about interference, channel congestion, or packet loss. A neighbour's Wi-Fi on the same channel 10 metres away causes interference that does not show on your signal bars but absolutely affects streaming stability.
 
I had this exact situation — router 3 metres from TV, full bars. Tested packet loss with a ping command: my Wi-Fi showed 1–2% packet loss during evening hours. Ethernet showed zero. That 1–2% is invisible for most internet use but causes IPTV buffering because live streams cannot recover dropped packets.
 
UK user — moved from Wi-Fi to Ethernet when I ran a cable last year. The difference was immediately obvious. I was getting maybe one freeze per hour on Wi-Fi during peak time. On Ethernet over three months I have had essentially zero.
 
If running a cable is difficult, a powerline adapter is worth considering. You plug one into the wall near the router and another near the TV, and it carries network traffic through the house wiring. Not as good as Ethernet but far more consistent than Wi-Fi for streaming.
 
I use a TP-Link AV1000 powerline kit. It reduced my evening buffering events by about 80% compared to Wi-Fi. Speed actually dropped but the consistency improved dramatically. For live streaming, consistency wins over peak speed every time.
 
Another option is MoCA (Multimedia over Coax) if you have coaxial cable in the house — common in US/Canada homes. Uses existing TV coax wiring for network traffic. Excellent performance, similar to powerline but generally more reliable.
 
Australia — moved my Apple TV from Wi-Fi 6 to Ethernet even though it was the newest Wi-Fi standard. Still noticed an improvement in stability during major sports broadcasts. The consistency advantage of a physical connection is real regardless of Wi-Fi generation.
 
One more thing worth mentioning: 2.4 GHz Wi-Fi is much more prone to interference than 5 GHz. If your TV is connecting on 2.4 GHz, switching to 5 GHz in your router settings can help before you commit to running a cable.
 
Check which frequency your TV is using in the network settings. If it is 2.4 GHz and your router supports 5 GHz, switch it first. If that does not help enough, then the cable is the proper fix.
