When trying to use a static IP address on my router, it at some point gets "hung up". My modem is still connected but the router is not connected to the internet untill I reboot it or change it to get IP adress DYNAMICALLY FROM ISP.
Possible causes:
1.My modem's log shows "SYNC Timing Synchronization failure - Failed to receive MAC SYNC" warnings (which from reading forms sounds like there might be a band connection/wire or frequencies get wonky)
2. My ISP (spectrum) has told me ttwo different things: that I can use a static IP, and that I can't becuase they change IP's every ~2 weeks. So far my IP address has not changed (over a month).
I'm not sure if 1 is the root cuase, but I wonder if for 2 I could write a script that would rebot the router if lost connection connection to the internet for more than a minute or so BUT have it keep the same IP address.
I can post logs from my router &/or modem but I didnt find anything to revealing on either of them. I wonder if there is an option to have the router ouput more indepth logs that might pinpoint the issue.

Most ISPs, at least for home users, don't give out Static IPs and only support Dynamic IPs for that same reason, they need the ability to change the WAN IP. Some businesses pay for static IPs which ISPs support for small businesses. So what your seeing is a results of the ISP protocole for you is set up for Dynamic IP addressing on the WAN. The router is hanging up and can't connect since the protocol is Dynamic and not static coming from the ISP.
Sorry should of specified this only happens between 1-3 days. And the IP always goes back to the same “static” IP (i.e. a script to reboot router with the same static IP would work). The reason I am trying get a static is to work is so I can ssh in remotely, unless there is another way around this?
So you have configured the WAN side for a static IP address from your ISP? Or is the router using Dynamic DHCP to detect an IP address from the router?
What is the Mfr and model# of the ISP Modem the router is connected too?
If you use a dynamic dns service like noip.me then you can ssh to that hostname and it will connect you to your network.
e38BimmerFN Correct. I am not using Dynamic DHCP to dected the IP from the ISO (I do use DHCP to assign IP's to my conected devices though). The Static IP I am using is from the ISP and has not changed.
I use my own router it is an Arris SB8200 ( http://www.arris.com/surfboard/products/cable-modems/sb8200/?gclid=CjwKC...).
I doubt this log will shed any light on anyhting, but it shows when the router loses internet conectivity (when using static IP), and when I try to diagnose the problem via the GUI, it just reboots but switches and gets the IP Dynamically from the ISP.

Do you still loose internet if you set the router for Dynamic DHCP instead of Static?
BTW the SB8200 is a modem, not a router.
It's possible that even though your getting a static IP address from the ISP, that the router also doesn't need to be actually set for static since technically, the IP from the ISP will not ever change if they have assigned you a static, so the modem will always pass thru the static iP address. So you could just leave the router set for Dynamic DHCP and it will just always see the Static coming from the ISP modem.
I don't lose conection when the 7800 is set to DHCP. Lol, I was a few drinks deep when I wote the post so no suprise I said it was a router haha (may or may not be now a few deep now too ;) ).
Most importantly though, your 100% right. I can still SSH in using my ISP's "static" assignned IP, even though my 7800 is pulling the IP dynamically. I don't know why I didn't try that before... Guess I figured it just wouldnt't work. But thanks for the Solution!
