Anyone else notice issues with the Netgear CM1150V running on Comcast with the V2.02.x firmware? Particularlly with LACP/LAGG (IEEE 802.3ad) Ethernet Port Aggregation Enabled? I have noticed this...

Is your firewall LAG supporting and you have it enabled and connected using both LAN ports for LAG with the modem?

Others are seeing similar issues:

Yes- everything is configured correctly in terms of LACP/LAGG and using both ports. As I mentioned, the Motorola modem didn't have this issue with same configuration. It most likely isn't on the firewall end of things.

Comcast discussion thread link, found another user with same issue with same modem and firmware:

I believe NG is aware of this issue. Something to contact them about if you feel the need. No idea if or when it will be fixed.
