Someone asked the same with the Xperia Z4 Tablet.

@uliwooly
Just try to reboot under safe mode and test the wifi
If everything is fine then u may have a malware app which cause the Internet buffering
Uninstall the last app u just installed and it may solve the problem

That's exactly what I'd suggested
