My C7000 router is causing network attached devices to intermittantly drop connection for about 30 seconds before restoring. Whenever this occurs, I check the router log and see one common thread. An Iphone in my house is showing DOS attacks, Ping of death, teardrop or derivative. Also, the IP associated with the phone appears to be a WAN IP and not a local IP received from the router. I've seen some threads about this, but, no posted fix. Is this an IPV6 issue??? I see someone stated the modem is not interpreting the address correctly for IPv6 from the phone (malformed packet), but, doesn't say how to correct. I don't think I can turn off IPV6 from either the phone or the modem..is that correct? Can I prevent the model from giving out any IPV6 addresses? There are only a few options under advanced setup / IPV6 and none are to disable. Truthfully, I don't even know if that is the issue. All I can say is 1 iphone in my house appears to be causing issues with the modem/network and I'm looking for a fix. Very frustrated with this problem!
