Hello,
I have noticed some occasional network issues. I currently have the 1200/40 cable internet plan and utilize a Motorola B12 modem with a Ubiquiti Express 7 router/gateway.
My modems logs indicate I am having trouble maintaining an upstream lock, I seem to have a lock at least as of looking today, but my upstream power levels definitely seem to be on the high end which is leading me to believe that when this spikes out of spec, my upstream lock gets dropped. My downstream data seems to be okay, although channels 25 and 32 do concern me as 25's corrected number is definitely not valid and I seem to have uncorrected errors on 32.
Anyone know what I can do to fix this? I live in an apartment building so my access to the line into my building is quite limited. Would it be possible for xfinity to run some sort of signal check or maybe evaluate the health of the line I am on? I am going to try and replace the Coax cable I can access with new cables to see if that helps as well...
