try to stop in the saved wi-fi network you use , into privacy - 'use random MAC' , changed it to 'use device MAC' , many routers had issues with this one , it's good for random wifi open network , but for your personal one , makes such issues

for the -17 transient error on device integrity check - the only needed is to uninstall updates or clear all data for play services , then no restart is needed, just search in play store or google.com 'play services' to go to the play store link , where you can directly click on 'update' button to update them the latest , after that should be working normally , had the same issue popup out of nowhere again on 2nd my device yesterday and this fixed it fastly , so it's defenetely related to bad/corrupted play services modules , most probably to the droidguard virtual machine code that is downloaded/updated automatically by the play services , so in theory it can be fixed by itself after some time when new version is downloaded
