Is there any benefit to have a wired backhaul for an Orbi Mesh system?
Hello everyone, Apologize for the lengthy post in advance, but wanted to give some background first. Product: 1 wireless RBR750 router, 2 satellites RBS750 Home Size: 2 story, 4100 sq ft Cu...
Yes- it’s like what I said above, my ISP is Comcast, and these are the specs I found on their website. The range is pretty broad, as you can see. You may have to do some hunting to find what the specs are for your ISP.
Comcast:
Upstream Power Level: +25dBmV to +54dBmV
Upstream Signal to Noise Ratio (uSNR): >31dB
Upstream Receive Power: -2dBmV to +2dBmV
donawalt on the Xfinity forum, some of the 'experts' firmly disagree with those specs. They are stating that upstream power should reside around 35-50 dmbV as the optimal range and that my current levels now do not offer a buffer for fluctuation. They also mentioned that some modems have chipsets that are slightly more tolerant in higher max thresholds than other modems, which may explain why my modem hasn't rebooted or dropped connection.
I'm tempted to contact Xfinity to see if they can check out the connection from the street to my house, but on the flip side, I don't want them to inadvertently screw anything up which they have done before... The "wait and see" part has been fine so far, as I haven't experienced any internet issues yet with my MoCA setup, but not sure if I continue to wait or if it's worth it to get a tech out.
"some of the 'experts' firmly disagree with those specs." - sure - everybody has an opinion. But I would also be shocked if they come out when the levels are within their own specs.
You haven't shown your modem status page (there was one image post that did not show up for me in your post earlier), are you getting lots of uncorrectable errors on a daily basis? In your log, are there a lot of CM-STATUS messages, especially 16 and 24?
Since I installed the new splitter, I'm getting 51-51.5 dbmV for upstream power across the 5 bonded channels and no uncorrectables. CM log is empty.
Sounds excellent! If it was me I would just watch it - with no errors and no warnings, it's hard to imagine a concern imho.
