The main takeaway
The biggest improvements come from addressing the actual weak link. Device organization and a stronger mesh backhaul are more useful than changing unrelated settings and hoping for faster Wi-Fi.

Find the weak part of the connection
This March 2023 guide followed my beginner networking series and collected ways to improve everyday Wi-Fi. Before changing anything, compare the same device near the router and in the problem room. Check whether the issue affects one client or several. If a wired test is already slow, moving a wireless satellite won't fix every upstream limitation. A useful baseline keeps you from mistaking random variation for an improvement.
Make the device list understandable
I showed a crowded list from my old network with names I didn't recognize. Renaming devices by what and where they are makes troubleshooting much easier. An unknown label isn't proof a neighbor has connected: legitimate devices can use obscure names or appear as old entries. Match the client with its app or hardware information, then decide whether it belongs. Strong credentials and appropriate guest access still matter.
Separate DNS and configuration from radio strength
The video includes settings such as DNS alongside wireless improvements. Keep their effects distinct. A different resolver can change some lookup behavior, but it doesn't strengthen Wi-Fi, increase the router's radio range or guarantee that an internet provider cannot observe traffic. Change one setting at a time and test the problem you're actually investigating, rather than treating every configuration option as a speed boost.
Give mesh nodes a better route back
The strongest practical example came from the related Ethernet-backhaul test: wiring the satellite produced over five times the speed in that specific demonstration. The cable addressed a weak wireless connection between nodes; it wasn't a guarantee of a fivefold increase for every home. Where supported, Ethernet—or compatible MoCA over coax—can supply that path. If wiring isn't practical, improve node placement and check the mesh app's backhaul status before adding more nodes.

Will changing DNS improve Wi-Fi signal strength?
No. DNS lookup behavior and wireless radio strength are different parts of the connection.
Is an unnamed device definitely someone else's?
No. Identify it before concluding that it is unauthorized.
