losing internet access during heavy usage

[duronn]

Ok so during heavy usage (sometimes it takes heavier usage than other times) I seem to lose internet access for sometimes a few minutes and sometimes a few hours. My pc shows my network status as connected to the internet and every other pc in the house can still use the internet just fine but for some reason I can not. Restarting my pc/router does not seem to help and I have checked all drivers are up to date. Does anyone have any ideas that may help with my issue? Thanks in advance for any advice.

Check with your ISP

Are you using the modem supplied by the ISP?  They are typically lower tier products and may be suffering from overheating or other problems.  You do not say if yoru connection is wired or wireless; which is it?
