インターネットでしらべる
インターネット - internet
調べる --しらべる-- (v1,vt) to examine; to investigate; to check up; to sense; to study; to inquire; to search
Actually, I'm not really sure about this expression. I had it written down in my notebook during the class and marked as "researching on Internet", but is it the same as "surfing the Internet"?
google gave me another option - しらべるネット, so I'm making a wild guess that しらべる is the verb to use for spending endless hours in Internet.
しらべる is worthy of some more attention:

調べ物 --しらべもの-- (n) matter to be checked or investigated
調べ --しらべ-- (n) (1) investigation; inspection; examination
調べて置く --しらべておく-- to examine beforehand
調べ直す; 調べなおす --しらべなおす-- to re-examine; to review; to recheck
