Even though I'm located in a city and right next to an Interstate hwy with 5-bar signal strength, my connection always results around 580kbps, 137kbps, and ping varies between 69-449ms.
In speedtest.net app, for some reason the nearest server shown under "Settings > Change Server" is Wichita, KS at 46mi, which is nearly 1000mi away. After changing server to a closer city, the connection speeds do not improve.
Does anyone know how to tell speedtest.net my correct geographic location?
