Hello, I very recently moved into a new place where I decided to buy my own modem router instead of renting one. I picked up a brand new CAX80 from Best Buy and went home to set it up. I plugged the nighthawk straight into the wall with both the coaxial cable and power supply. The people before me left there modem router which was a "Arris TG1682G" and so I unplugged there's to plug in mine in the same spot. I went through the rest of the steps and downloaded the nighthawk app on my phone. I next went to go check it on routerlogin.com and I see that under "Cable Connection" it says that the status is "Poor", I click on it and it comes up with some cable diagnostics; now I'm not that good at reading them but I do see that the "Internet Access:" is green and the "Downstream Status:" is green but the "Upstream Status:" is yellow. I believe it not to be a problem with the power level but I do not know. Next I go and do a couple of speed tests on the app and I end up getting around 250-350 Mbps for download and only 10-15 Mbps for upload, now it says that this is "extremely fast!" but I strongly think both of these are much lower than what I should be getting because my internet service provider (ISP) is Xfinity and I am paying for the 1.2 Gbps plan (1200 Mbps), now I did some research and I see that you don't actually get that high of a number but I expect it to be at least be in the 700's for download and 250's for upload. The other thing I noticed is that on the nighthawk it self all the lights that are usually on are white (which is fine) but the upstream and downstream are blinking and not solid which may tell you something. I tried rebooting it once with the app and also unplugging it from the wall which didn't seem to do much. I really hope to get this working but if I can't I will have to return it and find something else.

My Firmware Version is: V2.1.5.2

My ISP and plan is: Xfinity and the 1.2 Gbps plan

My modem router is plugged straight into the wall

New CAX80 has poor cable connection issues.
