So earlier today, I wasn't able to discover Chromecast from my PC(It says something like "device missing" in Chromecast extension). However, my TV shows Chromecast is connected to my network, and the light on Chromecast is stable white. Then, I tried to reboot my router, and that fixed it. This is basically similar to the issues i had in the past where i could just fix Chromecast connection by randomly rebooting router and resetting Chromecast.
I was skeptical and decided to revert my changes on VPN firewalls. After a router reboot, Chromecast still worked!!
At this point, I don't think it's the VPN firewall settings that is causing this issue. This issue looks so random. I would try to go dd-wrt next and hopefully it will fix this issue properly.
You mention DD-Wrt are you using that?
Cause I notice most people having these issues seem to be using DD-WRT or Tomato and I'm starting to wonder if perhaps there is some issues with those Custom Firmwares being used.
I do know in the past before I Upgraded my router that I had problems with devices getting booted off the WiFi because I had too many devices connecting and it would seem that when a new device would connect, one would stop getting data despite the fact it said it was connected.
Now this shouldn't ever be the case with WiFi if it has an IP it should not have a limit but I am wondering if your experiencing what I was experiencing before I Upgraded....
Not suggesting you need to upgrade mind you just that what your going through sounds similar to what I went through.
When I bought the new router (LinkSys N900) the Box had this chart of Router Groups and which router was best for X number of devices.
Low end for less than 3, High end for 7+ with the last group being for 7+ and HD.
This chart went against what I believed I knew about WiFi limitations which I thought was only IP and DHCP based...
I wrote it off as pure Marketing with the intention of getting you to buy the most expensive router they had...(which I was going to do anyway LOL)
I'm starting to wonder if maybe there is something to that....Sure would explain my problems with the router that made me upgrade in the first place.
