TP-Link TL-WPA4220KIT AV600 Wi-Fi Powerline 2-Port Adapter Kit

A powerline WiFi booster uses your home's existing electrical wiring to extend your internet to rooms where WiFi can't reach. 1 adapter plugs in near your router, while the second goes in any room where you need internet. It broadcasts WiFi and gives you 2 ethernet ports to connect a smart TV or games console.

Set-up takes just a few minutes. Plug 1 adapter into a wall socket near your router and connect them with the included ethernet cable, then plug the second adapter where you need internet. Press the Pair button on each adapter and the WiFi Clone button to copy your router's details, so your phone, tablet and laptop connect automatically.

The kit supports up to 600Mbps over the powerline connection and up to 300Mbps over WiFi. Real-world speeds vary depending on your home's wiring quality, with most homes seeing 50 to 100Mbps. The ethernet ports are rated at 10/100Mbps, so wired speeds are capped at 100Mbps, which is plenty for streaming, browsing and everyday use.

Yes, it works with any router that has an ethernet port. It also works with all HomePlug AV and AV2 standard powerline adapters, so you can expand your network with other TP-Link powerline products if you already have them.

Yes, you can expand the network by adding more TP-Link powerline adapters that use the HomePlug AV standard. For best performance, choose adapters from the same AV600 series, as mixing different speed tiers can reduce overall network speed to match the slowest adapter.

AV600 and AV500 refer to the theoretical maximum powerline speeds of 600Mbps and 500Mbps. The AV600 is the newer version with updated hardware, but both deliver similar real-world speeds since the ethernet ports are limited to 100Mbps. If your internet speed is below 100Mbps, you won't notice a difference between the 2.

The WiFi Clone button copies your router's WiFi name and password to the extender with a single press. This means your phone, tablet and laptop connect to the extender automatically without re-entering any details, so you can roam seamlessly across your home on the same network.

Yes, the kit is well suited to streaming HD content and casual online gaming. The wired ethernet ports give a more stable connection for games consoles and smart TVs than WiFi alone. Competitive gamers may notice occasional latency spikes, as powerline performance can be affected by heavy appliances on the same electrical circuit.

Yes, powerline adapters work really well for homes with thick walls or multiple floors where WiFi struggles to penetrate. The signal travels through your electrical wiring rather than through the air, so walls and floors don't block it. Both adapters need to be on the same electrical circuit, with range extending up to 300m over the wiring.

First, check that both adapters are on the same electrical circuit and that the Powerline LEDs are lit. Try plugging them directly into wall sockets rather than extension leads or surge protectors, as these can interfere with the signal. If the issue persists, press and hold the Pair button for 6 seconds to factory reset, then re-pair the adapters.
