Good wired but unusable wireless connection,
Verified Purchase(What is this?)
This review is from: TP-LINK TL-WPA4220T KIT AV500 Powerline 300M Wi-Fi Extender/Wi-Fi Booster/Hotspot with Two Ethernet Ports, Three Units Pack (Easy Configuration, Wi-Fi Clone for Smartphone/Tablets/Laptop) (Accessory)
I bought the TL-WPA4220KIT to increase my wireless access in an upstairs bedroom. I connected the TL-PA4010 unit to a mains socket downstairs and to my router via an ethernet cable. I then connected one of the TL-WPA4220 units to the mains in the bedroom. I tested the internet access by connecting a laptop via ethernet cable to the TL-WPA4420 (ensuring that the laptop's Wi-Fi was disabled) and ran a speed test via speedtest.net. I got very good speeds of 75 Mbps down and 16 Mbps up. That is brilliant as that is about the same speed I get via an ethernet cable connected to my router. (My ISP is BT and I subscribe to its Infinity 2 internet service.) I then tested the internet access via the wireless signal from the TL-WPA4220 unit using the same laptop with the ethernet cable disconnected and Wi-Fi turned on and connected to the specific SSID broadcast by the TL-WPA4420 unit. Unfortunately, the wireless connection was sporadic at best. Occasionally it was as fast as the wired connection but usually it was very slow at about 5 Mbps down and <1 Mbps up. This meant that at best I could only get internet access to text-based sites; access to video content such as YouTube worked very poorly and usually not at all. I tried using different wireless channels on the TL-WPA4220 unit but changing the channels made no difference. I tried different laptops and a tablet and the results were the same. I also tried using the other TL-WPA4220 unit that came with the TL-WPA4220KIT and the results were equally poor with regard to wireless.
Given that the TL-WPA4220 provided me with excellent wired internet access, I then connected an old Wi-Fi router of mine to the TL-WPA4220 via an ethernet cable, turning the router into a dedicated wireless access point (having disabled DHCP in the old router). I now have excellent wireless internet access in the bedroom by virtue of my old router connected via ethernet cable to the TL-PA4220. I reliably get 35 Mbps down and 19 Mbps up. This workaround is not ideal but, in my view, most powerline adaptors that double as a wireless access point do so rather poorly. Maybe it’s the small size of the adaptor that limits their wireless capabilities; I don't know.
Thus the TL-WPA4220KIT, in my hands, provided excellent remote wired internet access but unusable wireless internet access. I am keeping mine because I have found a workaround that I can live with. But I would not recommend buying this for its wireless capabilities as you are likely to be disappointed.
