FVS-318N; FVS-318Gv2 and Arris
User SamirD may have found a correlation in this long saga of the FVS-318N and FVS-318Gv2 not managing a cold boot. It may have something to do with being connected to an Arris modem; one easy 'fix' ...
Very interesting that a router in between is getting these units working correctly.
And it's not the cable modem, but the configuration of the head-end equipment by the isp, typically made by Arris.
Does anyone have a Frys nearby? This $20 managed switch might be able to act as the filter and allow the 318G to work normally:
Or order it from newegg:
These managed switches should be able to 'filter' the packets even if they aren't using any other managed switch options. Cheap fix to the problem.
Thank you for putting this out there. :) So let me explain some of the theory and my experience that led me to this conclusion.
Back in the mid 2000s, I purchased my first vpn router, the cisco rv016. Attached to it were three 8/512k cable internet connections.
Everything worked well for years until the rv016 kept dropping one of the cable connections. After consulting with Cisco, the said that the rv016 is defective. So I bought another rv016--and it did the same thing.
This led me to investigate a bit and I found out that my isp had just upgraded to new head end equipment--specifically the Arris C4. One of the 'features' on this new head end was the ability to monitor if there was something connected to the user's cable modem (by sending a NACK packet if my memory serves me correctly). But that setting can be set ridulously high--100 packets/sec high in my case. So the rv016 saw that as some sort of attack and would disconnect that wan and/or reboot. It would continuously rotate because it was trying to provide some sort of access in the midst of this mess.
After over a month of sending logs to both Cisco and my isp, I was fed up and came up with my own solution--get some cheap routers and put them in between the cable modem and the rv016 to 'filter' these packets. And it worked.
Fast forward to today, and it seems the same solution works on the FVS318N and FVS318Gv2 when it is having uptime issues. Perhaps the same cause of the problem? This can be addressed in firmware (or may already be addressed incorrectly) so it isn't a hardware issue for sure.
My FVS318Gv2 exhibits this behavior everytime since the latest firmware update (I am connected to an Arris SB6183 and have been for over a year). On every cold boot it will respond for about 30 minutes and then it stops working. I can still ping it, but I can't sign into the admin pages and the unit stops passing traffic and assigning IP's. I worked through a trouble ticket with Netgear as I thought my unit went bad. Turns out that I have to sign into the web gui before it stops working after a cold boot and do a reboot from within the web gui to get it to work properly again. This works evrytime, but is not acceptable long term as if I'm not around to do it shortly after an unexpected power failure then the only recourse is to have someone physically reboot it and then get into the GUI quickly and do the reboot from within the GUI. Annoying. Not sure what is taking so long for Netgear to fix this.
Just to add that this ha been an issue on the forums since last summer. https://community.netgear.com/t5/Business-Wireless/FVS318N-FVS318Gv2-Firmware-4-3-3-8/td-p/1092233
Any update from Netgear on when this will actually be fixed so that we don't need to do the Reboot through the GUI band-aid?
Trouble is that they closed that thread down, perhaps because it included a second issue (the unit finding the firmware 'invalid or corupt')
My solution to this would be to go back to the firmware where this wasn't a problem unless you need a feature in the new firmware version.
Please tell, which version? I never saw a version that worked, but I didn't try each and every one.
