Hello,
It appears that I'm running into the same issue. I'll try to explain things in detail so that there is no confusion.
Basic Info:
My WLAN Settings:
Services:
Everything appears to be identical to those from sevenseventyeight. I have read some additonal articles that referred to running a 'show airgroup blocked-services id' command, but when I run it, I get a parse error.
I also read in a Google help article that talks about disabling Client Isolation (https://support.google.com/chromecast/answer/3213084?hl=en) , but I'm not sure where I do that.
Since this is a very basic home configuration, I have supplied the overall config file.
I hope I have provided enough information. I look forward to a response.
Chris
