I'm looking to add a wifi range extender and have decided to go with TP_Link's One Mesh system, specifically the RE300 AC1200 unit. However in order to work as the seamless One Mesh solution, I'll need to upgrade from my TP_Link C59 AC1350 router to one of the TP_Link routers on their One Mesh compatibility list. I'm looking at the C7 AC1750 (v5.0) unit, it's on the compatibility list and is at the desired price point. What I need to know is anyone with a C7 are you getting at least -73 dBm signal strength in an indoor distance of about 60 or 70 ft with at least four regular 2x4 and gypsum board interior walls to penetrate. That would be the general path to where I want to RE300 plugged in which should allow it to provide fair signal to the swimming pool. That would put the RE300 about 30' from our pool area with the RE300 high mounted approx 7' up the interior side of exterior wall that faces pool. This wall is standard 2x4 studs with brick veneer on exterior side. House is single level. There's the plan. If the C7 is powerful enough to get at least -73 dBm signal to the RE300 I should be able to pull off poolside wifi this summer for under $100 total.
