This static ip system worked fine until yesterday. Been using it for 20 years.
I am thinking it may be a gateway upgrade like somebody suggested.
I will try to get somebody from the company to come help.
Spectrum just bought brighthouse, so thy are probably fiddling with everything making those wonderful improvements.
Here is some info you asked about.
The nameserver option in the interfaces file is ignored by the gateway.
When I could log into the gateway formerly I read its nameserver and they use their own.

So you do have a network connection then? The advice I gave you was under the assumption that you had no network connection. When you say you have a static IP address, do you mean you typed it into /etc/network/interfaces? I doubt that would work. Post the output from ifconfig and the contents of your /etc/network/interfaces file.
If the problem is what's in /etc/network/interfaces, then this should fix it temporarily, until the next reboot:
dhclient -v `ifconfig | grep ^e | cut -d' ' -f1`
You would have to do that as root and it may be hard to type. there's backticks or graves in there. If you're not familiar with that syntax it might be confusing.

> It probably goes without saying but after you power cycle your gateway, you should probably reboot your ubuntu machine too. And then make sure the cable is well seated on both ends. Even if it's clicked into the jack, there can be enough play to keep it from connecting. After that, you should run linux networking diagnostic tools. Start with ifconfig. Look for an interfaced named something like eno1 or enp30s25 or like that. If you run ifconfig and no interfaces starting with an "e" are listed, then your network interface is busted. Lightning strike maybe? Something like that. If youfind an interface listed, try running dhclient on it, "dhclient -v eno1". If that errors out, it is probably a cable or the gateway. If dhclient does not error out, you will probably have your network back until the next time you reboot. If that is the case, then see if your interface is listed in /etc/network/interfaces. If it is, then your problem is probably in that file somewhere. If not, then it'

>> Can you try with real ethernet? Can you plug an ethernet cable into your machine and the router? Since it suddenly stopped working and you know your router password, I think it's either something with your ISP, a bad router or switch (they wear out) or a bad wireless card. You could also try plugging the ethernet cable directly into your modem and your machine to eliminate the router.
