FVS336GV3 loses WAN connection
We have an FSV336GV3 Prosafe Firewall. It is using the latest firmware (version 4.3.5-3). It is connected to an Xfinity labeled DOCIS 3 cable modem. Periodically (like once a week at times) it los...
Thanks for the feedback. I'm glad to know that your internet connection through the FVS336Gv3 is still up and running.
I research about the logs you posted and found out that these logs are generated when there is malformed packet detected. When a packet with error is received by the interface of the router, it will throw this log and dropping the packet. The 'error code 10' is a length mismatch error.
Since the internet connection through the FVS336Gv3 is now fine and if ever the logs your posted is not of your concern as of the moment, I encourage you to mark the appropriate reply as the “Accepted Solution” so others can be confident in benefiting from the solution. The NETGEAR Community looks forward to hearing from you and being a helpful resource in the future!

Hi dsteinbo,
Let us isolate the problem. Kindly answer the questions below:
a. If you will connect a PC or laptop directly to the Xfinity cable modem, is the internet connection just fine?
b. Are there any recent changes on the settings of the FVS336Gv3 or within your network setup that might have triggered the problem?
c. Have you tried to factory reset the FVS336Gv3 then reconfigure it from scratch and check if the same problem will occur?
I suggest you to try using WAN 2 port and observe if same problem will occur. Let us know the result.

Thank you for your quick reply. There have been no recent changes that would cause this behavior. The behavior has been going on for several months--I just didn't bother to ask Netgear for diagnostic suggestions until now. I have connected the unit to a different port on the Comcast/Xfinity cable modem to see if that makes any significant difference. The time interval between Internet connection "failures" can be as little as a day or as long as several weeks.
As I try each one I will let you know the results (Are there particular elements I should "log" in the unit's log that would provide useful information to you? If so please let me know and I will enable them.
