Sometimes it's a problem at the main office. Sometimes, it's a local relay somewhere. But they should be able to narrow things down a little.
Hope this helps.

Ever since upgrading to 200mbps internet, I've been losing connection for a few seconds, every few minutes. This happens on all computers connected via ethernet. I've tried everything I can think of, and that I've found on the net with no success. Does anyone have anything that I may have missed? Here's what I've tried:
* New wi-fi router
* New cabling
* New switch
* Changed ethernet adapter settings to disable Green and Wake on magic packet
* Changed adapter to 100mbps half duplex
* Reinstalled adapter
* Disabled DHCP at the router
* Changed DNS to google
I'm at my wits end. Short drops are fine for web browsing, but terrible for everything else.
