Most of the day, I’m writing or gaming on my PC, where an Ethernet connection keeps things snappy and consistent. My phone and TV, however, are still susceptible to the mood swings of Wi-Fi, where unexplained latency can creep up anytime. Either YouTube videos would take an arduously long time to buffer, or sharing images and videos on WhatsApp would stall inexplicably. I’ve tweaked many router settings already in an attempt to remove possible drag on the Wi-Fi, but the performance was still not where it used to be. Bandwidth was not the problem, and I was running out of quick fixes. That’s when I decided to experiment with the router’s transmit power, a setting that I always kept at 100%. Reducing it actually improved the Wi-Fi speed and latency on my phone, and I wish I’d tweaked it sooner. Lower transmit power can actually improve your Wi-Fi by limiting the interference from neighboring networks and allowing easier communication with client devices.
