30Mbps instead of 300Mbps and daily spontaneous router reboots
For the past month or so, I'm only getting 10% of the download speed of my plan (300Mbps) and every day around the same time (10:30am or so) my router spontaneously reboots, and takes sometimes upwards of 30 minutes to come back up. Some days it does this 2 or 3 times.
I did a "chat" on the comcast website a few days ago, and the support rep told me I had to contact my modem maker (since I own it) -- which I did, and Arris told me that the power levels are out of spec. Some (but not all) of the downstream channels are lower than -15 dBmV and some of the the upstream channels are lower than 33 dBmV. There are also a lot of "Uncorrectables" for several of the channels.
Yesterday, I check it and and saw that the downstream power levels were all in spec (all around zero!), and my download speed was back where it should be (~250Mbps)! Yay, right? No. 2 hours later, I check again and it's back to 30Mbps and the power levels are below spec again, and then as I'm looking at it, the router spontaneously reboots again.
This is all on a wired gigabit ethernet connection, so slow wifi is not the issue.
Apparently there are signal issues in my neighborhood, even though the comcast website (and the support rep I chatted with) say there are no issues on their end. I've talked to other people in my area who also have the rebooting router issue.
What's the best way to get this escalated so an engineer can look at it?
Thanks in advance,
