Just to rule it out, I got a new modem from my ISP, and that still did not correct the bandwidth issue. This made me very frustrated, so I figured I would reset the Balance One to the factory settings and run the speed test. Boom! The bandwidth is back to 450+ Mbps. Now I know that it must be a setting. I put my configuration back in one setting at a time testing the bandwidth after each setting was applied. QoS is the problem. Whenever any QoS setting is applied, the bandwidth is essentially cut in half. I’m not sure if this is Peplink’s implementation of QoS, or if it is a firmware bug. If it is a bug, I am unsure how to report it. If this is by design, I believe it to be a poor choice. At a minimum, I would recommend that it be documented in big bold letters, “If you turn this on, your bandwidth for all other applications will be reduced dramatically!”
