In my business I have internet that is provided by the local county phone company.  I don't know the "technical" name for the type of system, but there is antenna on the roof that points to a tower.  The tower sends the internet signal to the antenna.  A cable runs from the antenna to an "injector" (power supply with 2 ports.)  One port has the cable from the antenna in it, and the other runs to a router.  The router has 2 cables from it...one to my main desktop, and the other to a work station. The router is also wireless, so it also gave me a wi-fi signal in the office, too.  A couple of days ago internet connectivity became very inconsistent.  All the resets in the world made no difference.  It eventually got down to where it only lasted about 5 minutes then go away.  Everything showed I was connecting to the router okay...just no access to the internet.  When I removed the router from the setup I had internet access on the main desktop.  Hey, easy diagnosis...right?  Bad router.  I had two new ones on hand.  Installed new one....no internet...same issue.  Tried next new router...nope...same thing.  Three bad routers in a row? I don't think so.

I personally know they guys that are the techs for the internet company.  One came out and messed with it for a while...and it began mystifying him.  After conferring with others they began looking into IP address issues.  I had originally called them and they had told me that my system was DHCP Dynamic, and that my router could automatically take care of that.  Well...it should have but it didn't.

The tech finally said he would try using a static IP setup.  After he got through entering the numbers....wha-lah!  Everything came back...both desktops and the wi-fi internet.  He was actually sort of mystified as to why it would switch back to static IP after having been setup up on Dynamic for so long.  He thinks the antenna may have gotten "confused."  Anyone willing to take a guess at this as to why?
