The modem is provided from my isp i believe its an adtran 620. The xr is plugged into the modem/ONT via ethernet, and all devices are connected to the xr. I dont know what mode it is in, i have not messed with any of those settings so im not sure.
I have had this router for about a month now and i have had constant issues. I have 1gib fiber up and down, this is my connection benchmark and I have QoS on at 70%. I have tried with QoS on and off. I always have a lot of issues while someone is watching TV aswell. Very frustrating because gaming is almost impossible if someone else is using the internet. I have tried everything and read a lot of forums and nothing has helped. Hopefully someone here can help me solve this issue.
