So, I think i kinda know what the outcome is going to be, but I wanna post this up anyways to get some feedback on my connection as you lot know a lot more than i do about this stuff 🙂
My VM connection is broadly stable - don't have many noticeable issues with either speed or latency. I am on the 200mb service with a hub2ac, running in modem mode, terminating the coax connection.
From the reading i've done, particularly from a recent post by @andruser (very informative) as far as i can tell, all of my power levels and general stats are within spec and nothing to complain about, but one of my four upstream channels struggles to negotiate/maintain a QAM of 64 and I do get issues from time to time..
I've had a BQM up and running for several weeks and it doesn't look terrible, but i do get some packet loss from time to time and i'd (obviously) like to eliminate it if possible..
This is an example of a typical day.. (workday whilst WFH + three kids in various school-related google classroom/zoom sessions + me in teams calls etc..)
This is an example of a bad day. (workday)
This is an example of the intermittent packet loss that i see on my connection from time to time (i'd say one day in three - this particular graph was a Sunday, so no obvious workday traffic between 9 and 6)
Now, as i said at the top of my post - as far as i can see, everything is within spec from a power perspective, so I'm guessing VM would take one look at this and say that everything is ok from their end.. but presumably there's *something* that's not quite right, given the 32QAM and the post-RS errors?
Speaking of post-RS errors, I don't have huge numbers, but there's enough - the stats i'll post from the hub in the next post are after I did a reboot at about 7pm last night..
no change, still one channel that is unable to negotiate a QAM of 64 and flips between 16 and 32, when at 16 upload speed halves and latency increases - most noticeable when I join a teams meeting, I can tell the QAM has dropped when it takes several seconds to join a meeting...
Thanks for coming back to me I can see you do have one of our older routers the 2ac and it looks like you have a 3rd party router, I have looked and I can see one of your Quan is incorrect, I advise putting our router back into router mode and perform a pin reset, also check all youe external and internal cables are hand tight.
I am indeed using an older router with a 3rd party device behind it.
accept that you guys only support router mode etc, though I don’t see how connection negotiation on the WAN side could be affected by being in one or other mode.. the modem is the modem and the cables are the cables, makes no difference (in my head at least - though happy to be schooled) whether the hub operates as a modem or a modem+router.
Ill pass on this for now - I don’t see how a reset / check in router mode does anything for me - unless it’s a mandatory step of the troubleshooting process before any other steps can be taken...
