Hi, I currently have TL-WPA4220 KIT, which gets me around 50Mbps rate (according to tpPLC) and up to 20Mbps actual speed (speedtest.net). Both with cable and wifi. The building has poor wiring, that's a given :) So the problem probably lies there. There also might be different circuits...

The question is - my model is somewhat outdated. Will buying newer model (say TL-PA7010 KIT) help me to improve the speed or the quality of wiring is a hard limit, and I won't get any more speed no matter which model I buy?

Thanks in advance!
