Turn off the internet. I usually start out by creating an offline reference material dump (offline docs - zeal, offline stackoverflow - kiwix, ebooks, pdfs etc) so I have no great excuse to get online. Then I setup a schedule in my router to block all internet traffic for N hours. For me getting work done also depends on the environment I am in. If its a problem that I am making progress with, then I can sit alone for hours and work on it. But if its not going well, I need to be around others who are all looking busy and productive :) That has some weird effect on me to stay focused.
