Hello All

I currently have a number of the TL-PA211 AV200 200mps adaptors throughout my house to distribute my broadband.
My wifi signal from my router is shocking so I am looking to purchase the TL-WPA4220T broadband/wifi extender kit.
If I replace the PA211 base unit with the WPA4220 base unit will the PA211 plugs throughout my house still link to the new WPA4220 base unit?

Many thanks
