Regular Drops In Wired Internet Connection?

i'm having an issue where my internet connection will seemingly drop for a split second, and then reconnect.for example, i will be signed into irc and will have a momentary drop in connection which boots me out, and then i will instantly reconnect.another example would be when watching a streamed video (Internet). i will be watching a video and then the buffering would stop, until i manually navigated to a couple of seconds later, and then buffering would continue.a final example would be in skype, where people are constantly getting connect/disconnect notifications from me.i've had a go at pinging google (-t) to see if it sheds any light on the frequency of disconnection. it has an average ping of about 35 ms, and will occasionally spike to roughly 130-150 every 7 lines or so. but other than that it has no difficulty pinging at all.
