r8000p why would lan connections break when wan fails?
On my r8000p i have wired connections to my windoze server that runs dns, dhcp, web services, file shares, etc. On WiFi i have both windoze and i-thingy clients. When my WAN connection goes down th...

Why would dropping a WAN connection cause the LAN to misbehave like that???
It shouldn't. So some more details might be useful.
What firmware version do you have on the device?
A number is more useful than "the latest". (It may not be by the time people read this.) There can also be newer versions, or "hot fixes", that do not show up if you check for new firmware in the browser interface.
It might also help if you told people what the modem is in front of this router, if there is one. The make and model number could be useful. Is it, by any chance, also a router, with a set of LAN ports on the back?
The reason for asking is that a lot of people turn up here trying to put a router behind a modem that is also a router. That can complicate troubleshooting.
Firmware Version V1.4.4.94_1.3.56
the wan configuration is like this... which took spectrum a week to figure out and configure properly as we are their first home fiber installation town, and i am their first small business' account on that system... I have a static IP which is assigned to the r8000p, with ip = x.x.x.190, netmask=255.255.255.252, gateway x.x.x.189. the internet port of the r8000p goes to a spectrum router gateway with the x.x.x.189 ip which then goes to their fiber modem which is a brand new gb capable box that they upgraded me to when the old one had some kind of intermittent problem. only 1 port on the spectrum router is used, the one to my r8000p, the wifi ports are disabled as are all it's services like dhcp, etc, as far as i can tell their router is just passing through everything going and coming to my router, i tried to get more detail from spectrum about it but apparently only one person somewhere in their engineering group could even figure out how to provision it. i could get numbers off them but don't know if they are spectrum part numbers or something else so they may not be that useful. on the r8000p the dhcp, dns, guest lan, and lots of other stuff is disabled, i do dhcp and dns from my server on the lan, the r8000p does do nat for several incoming services used for ham radio stuff.
the real confusing part for me is that the server has static ip's for its network ports, 192.168.0.2 and .3, as do many of the single purpose windoze machines on wifi or ethernet ports and they all lose connections... or well maybe the wired ones might stay connected to the server, there are 2 special purpose machines on the lan that are wired ethernet to the router along with the server, they might still work but the only thing they connect to are outside addresses so they die anyway if the wan goes down... but all the wifi connected stuff is left stranded and can't even connect to the server, and they even lose active existing connections to the server which is really annoying!
