have a CM1200 cable modem that requires frequent power cycling because the downstream light starts flashing after a few days of use. I usually have to power cycle two to three times per week. My ISP, RCN, also known as Astound has checked everything and the signal(s) from them are in good order. I have had them to the house several times to evaluate this but to no avail. Most of what my wife and I do is not that demanding. My wife works from home three days per week, ten hours per day. I work three hours per day uploading medical data to my company. We do some streaming but no more than three hours per day average. The ISP says the problem is with the cable modem and the last tech I spoke with stated that it was probably a cache issue. Research on the internet points a finger at the ISP.
Any thoughts or ideas appreciated. The modem firmware is the latest from Netgear.
Thank you in advance.
