Some times I have to reset my ADSL modem, after that google search won't work, I tried browsing other sites like bing.com and duckduckgo.com without any problem, it just gets stuck when I enter either a keyword search on the address bar or an address with domain google.com
The web browser gets stuck showing a blank page with a progress bar at about 20%, but it's just the web page not the browser, I can open other tab and browse to bing.com for instance, and that page load just fine.
The browser is Safari 9.0 running on OS X El Capitan
