I have my Obi connected directly to my modem and my router connected to my Obi. I noticed that my download speed went from ~50 Mbps to ~18. I tried removing the router from the equation and just connected my computer to the obi which was still connected to the modem and the results did not improve. Why is the Obi slowing me down so drastically?
