I'm having a really bizarre problem with my home internet, specifically when I try to play flash games. The games load fine, but for some reason they disrupt the internet connection of every computer on my home network, specifically over port 80. All applications using other ports continue to function normally. Often I have to resort to rebooting the router in order to get port 80 working again.
As a web developer myself, I'm ashamed to admit I'm kind of stumped over this one. Does anyone have a clue what could be causing this behavior?
EDIT: Well, now I'm even more ashamed... Usavich rightly pointed out that port 80 is simply a destination port, not an outgoing/incoming port on my end. Not sure what I was thinking. Still, the pattern remains: normal web browser requests fail, while other persistent connections (iChat, Gmail) continue to function. I'm totally perplexed here.
Also I have reports that it's happening even without Flash being involved. The internet simply drops until the router is restarted.
EDIT 2: Just saw this question:
Seems pretty similar to my problem. I'm thinking this might just be a router flaw (mine is a Netgear WNR2000v3).
