over the last couple of days i keep losing internet connection ...now not all the connection just browser....if im downloading on say ie utorrent or newsleecher that still stays alive but if i start the browser on either my server or my pc sometimes it doesnt work....but if i take the network cable out and plug back in again or reboot the switch it works fine again for a few hours or so....now i am trying to figure out if its the switch causing the problem or something else like can it be cables as they are new....or ive opened a couple of ports on my router is it possible that would cause this....has anyone come across this problem thanks
