C7000-100NAS randomly drops internet connection
Hello, My C7000-100NAS modem seems to randomly drop it's Comcast connection. This happen on 2.4 ghz, 5 ghz, and wired connections. There is no pattern, however the dropped connection usually last...
It's interesting that Netgear has allowed this to continue on for two years. Same problem here, all the following messages repeat every 30-45 minutes. Talked w/ my ISP (spectrum/twc) and they came out tested the line into the house and from the wall to the router--all good. Troubleshot w/ netgear techs, reduce MTU size, factory restore, problem doesn't stop. Tech recommended replacing it if the factory restore didn't work. Fortunately I bought from Amazon and I'm awaiting the replacement tomorrow (but this five page message train doesn't give me much hope it will work, so if it doesn't I'll just go w/ a refund):
