upstream dBmv power levels are a bit low?
Hello everyone, i dont have any problems with my service at all but I logged into my XB7 the other day and compared my upstream power levels to Comcast's recommendations which is from + 38 dBmv to + 48 dBmv.
My power levels for the 4 upstream channels are attached in screenshot but for those who just wanna take my word for it lol here they are:
So they are a tad bit on the low end and after researching a little bit online about, the consensus seems to be there isn't much on my end that I can do as upstream power level troubleshooting is mostly done on Xfinity's end. Is this true? Or are there some things that I can try on my end to get my upstream power dBmv levels higher and within Xfinity's recommendations?
And like I said, I'm not experiencing any issues at all like dropped connections, slow downloading or uploading times, i'm just curious as to why my power levels are a tad on the low end?
What makes it even more perplexing, is my download power levels are SPOT ON with an average of 0.7 dBmv for ALL channels--which is great because 0.0 dBmv is considered OPTIMAL & nearly perfect for Xfinity.
I appreciate any input oradvice that anyone in this forum; or perhaps a former/current xfinity employee/technician can provide.
Thank you very much,
