Windows 7 professional. Office network. 3 pc's, one pc is a workstation that also is the server for their hospitality software. Recently had printer connectivity issues from server to shared printer. Took a netgear router and installed as a switch to network the printer as there are 2 pc's at the front and only 2 network jacks wired. - All of that is working. However, the 3rd pc in managers office can no longer connect to the server when I try to map to network drive. I know I probably need to change something in the router, but of course they don't know the password and it is not default. I don't want to have to do this unless necessary as it will mean I have to reset the router and therefore take down their network, (which means I have to work tonight. :/ ) Is there a way around this? If not, what settings do I need to change/add in the router?
