wndr4500v2 dropping comcast connection
i have motorola sb6141 cable modem. when pc is directly connected to the cable modem comcast functions well. when i connect to the internet thru my wndr4500v2 router with ipv6 set to WAN/dhcp LAN//...
Hi ElaineM,
I have found a solution to this problem. My firewall (Bitdefender) has a default setting to deny incoming ICMP v6 messages. Setting this to allow made the problem vanish.
What I do not understand is why direct connecting the PC to the cable modem worked OK as Bitdefender was still in the loop. Magic I guess.
I believe allowing ICMP messages poses a security risk which seems to be an IPV6 risk. Do you have a comment on this?
Thanks again :-)
Hi, Elaine,
Firmware Version is V1.0.0.60_1.0.38
I will try the hard reset later today. BTW can I backup my configuration and restore after the hard reset without re-introducing problems?
Yes, you may backup and restore.
Hi ElaineM,
Did a hard reset, reimported the backup and have the original results. Connects tp ipv6 for a short while then ipv6 times out.
One of our support team will follow-up with you for further diagnosis.
They'll be contacting you separately.
