off topic but tech related... my smart speaker has decided teh internet doesnt exist.

Network & internet
Wi-Fi • HomeNet_5G
No internet, secured
Connected, but nothing loads. Troubleshoot problems?
it worked yesterday. nothing chagned, as far as i know. the router lights look normal and teh other devices are fine. we have my kids cartoon time coming up again soon and i really dont want a repeat. where would you start? :) id love a fix that doesnt involve buying something new.
