I’m a nerd too but come on, he’s replying to an obvious joke with high school physics. There are more layers, do you want a more pedantic teardown?

• Most likely, the “Wi-Fi speed” the Reddit poster needs to improve is the data rate, not latency.
• The data rate can be improved significantly by increasing RSSI with a better physical setup, WDS, higher power etc.
• The latency cannot really be improved without changing hardware or software, as the highest impact one can influence is in processing by the router and device. Some settings such as DNS cache size can improve latency in some cases with some downsides.
