Good day! I am planning to buy a mesh wifi / wifi extender for my home. 

The router is on the first floor. I cannot use a Lan Cable to crawl up to the 2nd floor for my PC since it will be an eye sore and will pass through the stairs which will become eye sore. I am planning to buy a WiFi extender then connect a lan cable to the extender.

In my old house, my Download and upload speed tops at 400-500mbps now using only a WiFi adapter, peaks at 133mbps. 

Any recommendations what to buy? Looking at XE75 right now. But for those who have tried or almost the same situation as I have, your recos are highly appreciated.

I mostly play games on my PC. Dota2, Valorant, CSGO and such. 

Thank you so much!
