Recently had a client who went from a wireless internet connection to a 10x10 fibre connection. All of a sudden we cannot connect to any internal pcs like we did prior to the fibre. Nothing has changed except the connection type and provider. Its a Cisco RVS180w router and no VPN or anything else set up on it? Any thoughts or suggestions much appreciated.

RV180w doesn't have built in 10Gbps SFP or fiber ports. How does it get to fibre? May be a simple problem of port configuration mismatch

just to make sure understood right, all other internal pcs are still on WiFi? Is there isolation configured? Different VLANs can be configured theer as well. If you can send dump of configuration it'll be helpful
on system that moved, is it configured with DHCP? Does it get appropriate IP address and other settings? if you would like i can send you commands to run if you let me know what OS is on the system that is moved

Ok let me detail more sorry. They had a wireless internet connection running DHCP through a Server 2012 to about 6 or 7 Workstations. We changed providers to a 10x10 fibre conenction converted to CAT5 and into the router. Now we can connect to anything from the inside out but cant connect to anything inside from the outside.

how was provider connected before switching to fibre? Was it same direct ethernet connection to the same port (WAN port usually) or something different?
what kind of upstream protocol does it use? DHCP/PPTP/PPPoE or something different if you could get Network->WAN configuration definitions it'll be really helpful. And content of Status->Dashboard, especiall WAN part of that
