I am on the Gigabit plan. I have a MB8600 modem.
Last night, my modem rebooted after having been up for over 60 days. Not sure if something was pushed out, not aware of anything else losing power in the house. I noticed today that my download speeds were much worse than normal. Where as normally I'd get between 750 Mbps and 850 Mbps on my wired desktop, now I am lucky to get 350 Mbps. I've tested a few times though the day, including now (about 11:00pm PST).
Looking at my numbers, it appears that the OFDM PLC Chanel is just going nuts on the "Corrected" count. It is just constantly ticking up. Is that a sign of something wrong? Or can it be ignored? This was just captured now, 8 minutes after I rebooted things:
