My router spits out WiFi on 2.4Ghz and 5Ghz simultaneously. Both have different SSID's, but the same key. My laptop's wifi adaptor is poop and won't see the 5G network so it's connected to 2.4, my handset the 5GHz network. Because I thought chromecast needed to be on the same wireless network you were casting stuff from, it was setup to connect to the 2.4 band so I could cast from the laptop. If I needed to cast from my phone, I'd switch to the 2.4GHz network and cast from there. However, chromecast is visible on both networks (see the attachments) and I can cast from both my phone and laptop without doing any messing about. Looking at my routers IP table, it's only connected to the 2.4. Does that make sense (post and scenario)? What's the deal?
