Need some help here. I'm having trouble with my internet speed. I have the 150Mbps plan exclusively for gaming purposes, but it's not working well. I currently have the Cisco DPC3848V, but have tried the Hitron CGNM-2250 in the past without luck. The biggest problem I'm facing is that my download speeds only go as high as 35, and my upload up to 1.8 (the other day I got an unbelievable 56K, which I didn't even know it was still possible in 2018), which is very disappointing. I tried the DMZ method and the ip-passthrough without luck. I read a bunch of reviews about this issue and it appears to be a problem with this specific modem.
I've seen some people getting lucky with the new XB6 and am willing to try it. Or, if someone could give me a hand with what I have here, it would be much appreciated.
