Recently, I've been experiencing signal loss, especially in the basement. I want to go beyond a standard setup, but I'm not sure where to start. Even a single wall seems to significantly reduce signal quality. Options like changing the router's location, using high-gain antennas, or trying a mesh system come to mind. What are your recommendations? What steps can be taken, starting from the basics to more advanced methods?
What are the best ways to improve WiFi performance at home?

Alright, first things first—it's crucial to pinpoint the exact source of the problem. When you say "a single wall is killing the signal," I'm curious whether that wall is concrete, metal-clad, or something else. If there's a metal mesh embedded deep in the concrete, a 2.4 GHz signal can lose up to 70% of its strength, and 5 GHz might not pass through at all. Check your walls first; if there’s metal involved, try mounting the router on the opposite side of the wall in the next room. Also, position the router’s antennas horizontally instead of vertically—this helps the signal spread more evenly throughout your home.
Before jumping into a mesh system, it’s smarter to start with a basic upgrade. If you can’t move the router, consider getting a high-power WiFi adapter (like the TP-Link Archer T9UH) and plugging it into a USB 3.0 port. Just be careful—USB 3.0 can introduce noise, so keep the adapter at least 2 meters away from your PC. Lastly, if you’re pushing the 5 GHz band hard, move those devices to a room on the basement floor. While 5 GHz doesn’t travel as far, the signal quality is far superior.
