modem event logs only show the events when i did reset and nothing else.
Here is the screenshot of signal strengths
Comcast technician came and this time seems like someone logical and reasonable. He took some time to test inside and outside of the house with his modem to collect more stats. He observed some quick variations and errors at the start as soon as when modem was connected. Found that coax had bad connectors both inside and outside. I took some pics and will post later. He replaced both of those, and retested everything. No more sudden jumps in reading and no more errors. I will wait for sometime (few days) to see if I need to reset again or the problem is solved now. fingers crossed
Thanks Mark from Comcast.
Hope that things hold up for you. Good luck !
nope, after 2 days, same problem. this is eating my brain now. very tricky issue.
i called same technician and he checked online that signals are good. i keep doing reset everytime.
He suggested that it could be a voltage issue in the attic which is not the case.
Any suggestion here? how can I troubleshoot this when the internet goes off and modem internet light is still green.
