Right now I am working on PubSub chat for my application and as I go further it starts to break...
Actually, today I borrowed my friend's mac for testing and I saw, that when I use:
jsipfs daemon --enable-pubsub-experimantal
jsipfs sub foo
jsipfs pub foo "Hello"
it doesn't show up in my friends IPFS even when we were having same wi-fi network connection.
jsipfs swarm peers
shows lot of peers around, so I don't think that it could be caused by router or something else.
I am using js-ipfs 0.26.0 and js-pubsub-room also.
