To add to what MplsCustomer mentioned, this isn't Google stopping you using your speaker in different countries, this is something fundamental to how Wi-Fi operates.
Google Home and Google Nest products are optimized to work best with specific Wi-Fi standards depending on where they are sold. This means if you buy a product in one country, it may not work as expected, or may not work at all, if you try to use it in a different country than where it was purchased.
The first thing to try is to factory reset your speaker and retry setup. However, as MplsCustomer mentioned, Google Home and Google Nest products are not compatible with Wi-Fi systems, known as captive portals, that require you to login or register first to be able to access the internet. There are a couple of possible solutions for this:
- Check with whoever manages your Wi-Fi if they have a process to whitelist or register your device. They do this by allowing the unique MAC address of the device. Not all providers will be setup do this however. In addition, even this may not work on some Wi-Fi networks, as the administrator may have enabled a security feature called client or access point isolation, which prevents different devices from communicating with each other (i.e. your phone or tablet communicating with your speaker).
- Although unsupported by Google, you can try to use a phone or tablet as a Wi-Fi hotspot. However, this is not recommended and will use your mobile data plan, which could be expensive for you depending on the data plan you have with your carrier. Note you will need 2 devices to set this up.
- Turn on the Wifi hotspot feature on a phone or tablet. If you're not sure how to do this, refer to the manufacturer's support website.
- Connect a second phone or tablet to that Wifi hotspot.
- You can then use that second phone or tablet to setup your speaker and connect it to the Wi-Fi hotspot on the first phone or tablet.
- If you're able to use a wired network connection instead, you could invest in your own cheap Wi-Fi router, connect that router to the wired network provided and connect your devices to that router instead.
