Just for reference, I am actually a Frontier(ex. AT&T) customer, but figured I would post here due to the wider amount of people with these gateways here.
I don't know why, but I'm having terrible luck with my NVG589s.
My first NVG589 was a Motorola branded AT&T U-verse unit. It would reboot on its own all the time. The only way I could get it to stop rebooting every day(sometimes multiple times a day) would be to manually pull the power. That would keep it running typically for about 30 days or so, until it would basically lock up, forcing me to reboot it. That reboot would then cause it to go into the constant reboot cycle until I once again did the manually reboot. A never ending cycle. On top of that, if I were to click either the "Wireless Scan" or congestion scan buttons in the UI, the gateway would just crash(only happening on this first one).
So, I then tried to get a replacement gateway. The 2nd NVG589 was a newer Arris/Frontier branded unit. This one doesn't have the crazy reboot as the first one. Sometimes it does, but it only happens once and a while. However, this gateway still locks up roughly every 30 days. I have only been able to check the logs once as this was happening, due to it basically being impossible to get the pages to load most of the time.
The one time that I was able to check the logs, I noticed these new entries that I don't typically see -
L4 mcp[1268]: mcp: error sending membership query - No buffer space available
L3 dhcpd[1361]: send_packet: No buffer space available
L3 dhcpd[1361]: icmp_echorequest [Chromecast's LAN IP]: No buffer space available
Whenever it basically locks up, all of the TVs freeze up, no internet traffic passes through, and I believe no phone as well. It's not even possible to connect to the network during this time, since I can't get a LAN IP on my devices trying to connect.
I tried turning off IPV6, but that basically did nothing.
I didn't have an issue like this with my original 3801HGV with the same setup.
Am I just really unlucky, these NVG589s are buggy, or is my setup causing this?
Right before it froze up this time, I was poking around the gateway UI. Out of nowhere, it loaded the AT&T U-verse color theme with the Frontier logo for some reason. The Frontier UI color theme is a red/black/white instead of the blue/white of AT&T's.
The reboot itself on its own can't be a power issue, as least I think, since I've had the battery backup in it for a while(though it hasn't been it in for a while now). It would still fully reboot even with the battery.
Any idea/how this is occurring? No idea why it's saying no buffer space available.
My setup isn't exactly 'supported', but I don't really know how it would be causing an issue. I currently have my wireless receivers running through my RT-N66 in access point mode. I also have IGMP snooping/multicast enabled in the radio settings. My receivers never really have a problem. But then again, this was how it was with my 3801HGV as well.
If I'm remembering correctly, if I reboot the gateway myself prior to the 'roughly' 30 days lockup, it doesn't happen.
On this 2nd gateway, one time when it locked up, I went to go reboot it by the reset button(since it had the battery in at the time). When I did that, all of the lights were stuck fully lit until I went to take the battery out, so that I could shut it off.
I have tried rebooting every piece of my equipment(devices, receivers, my RT-N66 in AP mode) to see if it would have any effect while the gateway was locked up. It didn't.
