Hello, 

I'm using TL-WPA4220-KIT. I have 100mbps download speed from ISP. 

I've connected the powerline adapter directly to the modem, and both adapters are plugged on wall outlets.

I'm getting ~90mbps download speed with cable output, which is nice.

But the problem is the Wi-Fi. I'm getting ~5-10mbps download speed from same device that I'm getting ~90mbps download with cable.

I've selected 802.11b/g/n mixed mode, Auto channel width. 

Updated Firmware to 1.0.1 and disabled the power saving mode. 

I need 25-30mbps wifi download speed for surfing on web.

What should I do? 

Thanks in advance.
