Hi,

My home is two story building. My main router (Tp-Link Archer C6 V2)  located in upper floor. In lower floor I configured Tp-Link TL-WR850N as range extender and I cannot make this as access point as I have some limitations bringing the ethernet cable from main router to this one.  I used to get some WiFi network coverage in lower floor but not all the corners of this floor. Since my main router supports OneMesh, I wanted to buy one or more OneMesh supported WiFi extenders to increase the WiFi coverage in lower floor.   Please suggest OneMesh supported extender(s) for better coverage. My house is made with concrete walls and slabs and floor area is approximately 2000 SFT. 

My home office in upper floor and there is no issue in WiFi coverage and speed. In lower floor I wanted to have better coverage and at least 50-100 Mbps of internet speed. 

And also please suggest, configuring them as range extenders or OneMesh nodes which one is better for better coverage and speed. 

As of now I don't want to spend much amount on Whole-Home WiFi, please suggest me to extend my WiFi network that satisfies my requirement.

Thanks in advance.
