We just got AT&T fiber at our office and it's broken our in office network. We came off of dsl with a WiFi four port router and everything was talking to each other. They installed a ciena 3190 and a Edgemarc 4808, they ran one cat5 wire to the bosses PC, connected it to a five port switch along with the other office PC's. All office computers have considerably faster internet, but no longer talk to each other. AT&T is sending a guy out in the morning but just wanted to pick our IT guys brains here and see if the change from router to switch is what killed our internal system?

You need to declare the network as a private network in network and sharing center. It probably thinks the network you are now attached to is public and is limiting them from talking to each other.

Is that just the four office computers as private or is that including AT&Ts, what is that 4808, a router? I feel sorry for the AT&T guy tomorrow if I'm not busy. I feel real sorry for him if the boss IS busy...

The Ciena is a multiservice switch which is what the use to connect to the fiber cable. That is your network gateway to the internet. The edgemarc let's them run phone and other connections through the fiber optic. 

 

If you open the network and sharing center you can see if the network is set up as public or private for each computer. Each of them will need to be set to private to allow them to communicate.

 

Has nothing to do with the network protection built into the device connected to the fiber optic. There should be something there to catch the hackers.

Windows has 2 defaults for networks. Public and private. Public will restrict visibility between computers and is what you want when you connect on wifi somewhere. Private will let the computers share files and printers and stuff.
