I have tried all the solutions mentioned in the various books, app, etc.

1. What base station do you have?
2. What LED status are you seeing? https://kb.arlo.com/000039100/What-do-the-LEDs-on-my-Arlo-SmartHub-or-base-station-mean
3. Has this ever worked for you?
4. Is the base new or used?

The base station is used--by me for the last several years, successfully, in a home we just sold and now I"m trying to set it up at a new home.  

The lights go on for a few seconds, all three, then the left one becomes amber, the other two off.  Eventually the right light comes back on, sometimes amber, sometimes green, but the middle light never comes back on.  

I presume that I'm not getting internet connection but I've tried the on/off cycle many times, and tried different sequences of turning the station back on, as well as a factory reset several times.  I have tried the old, successful at the last home, ethernet cord and bought a new one, and plugged it into various ports on the router (xfinify).  I even went to eBay and bought a new used base station,  with the same result.  

I'm reduced to concluding that the problem is that this system is not compatible with the xfinity cable system.  Have you heard of that?  

Also, I connected the base station directly to a wall outlet.  Still nochnge.

I haven't heard of that, though it is conceivable.  Are you seeing the base station in the attached device list of the router?

Do you have an ethernet switch?  If you do, try connecting the base to the switch (and the switch to the router), and see if that works.

Problem solved! I went to ping.eu and checked port 455. It was closed so I opened it and it’s working well now.

Did you mean port 443?  AFAIK Arlo doesn't use 455.

It's unusual for 443 to be blocked, since it is used for https.  The base only uses it outbound, so there is no need to forward 443 to the base.

There was more to it.  Apparently Comcast had set my modem up for a remote connection of some sort.  That was changed also and maybe that was the trigger.  

I got the 455 port from an Arlo phone representative--quite difficult to access a real human voice but I did it.
