I just moved to a new apartment who has community solutions WiFi so they use your Mac number to add everything to their system. However when I moved in my Chromecast wouldn’t connect even after giving them my Mac ID. I’m looking to see if anyone else has dealt with this and can offer help.
All Google Home and Google Nest devices are designed for use on private, secure home WiFi networks. If your Chromecast could connect with the apartment network then it would probably either have AP isolation on meaning that devices can not communicate or everyone else on the network could see and communicate with your Chromecast.
Other users have reported using either a shared connection from a mobile device or computer or a travel router in these situations.
Thanks for your help here, Cathal_S.
Amy40, hope that helps but if you're still having trouble setting up your Chromecast, try to factory reset your Chromecast and get the MAC address during the set up and provide it again to your apartment's administrator so they can add it up in their network and once done, attempt to set up your Chromecast.
Note: Apartments often experience network congestion due to the high volume of tenants or networks.
