| and hope to fully resolve this weekend. Multi-level townhouse isn't great for wifi, but had an extender for a bit that seemed okay. When I wanted better internet service for streaming, I added the TP-Link AV500 and it's been great for Netflix and PSNow. What I don't have is the great wifi in the upper level. But I think I can resolve that coming out of the second port of the TP with a separate wireless router. I imagine it will be better than just a wifi extender.
Should be, as long as you don't buy an entry level access point. Get something decent with a couple of antennas and it should perform better.
You can also consider one of those multi AP solutions that Google and Netgear make. They're expensive (they both tend to go on sale for around $300 on a regular basis), and have 3 APs that spread out throughout a multi level home to provide consistent, single SSID wireless throughout.
