I'm far from an expert with networks but it's sort of fallen to me to try to get our office network improved. I work in a small medical practice with about 10-15 computers and 2 networked printers. Right now we have a Cisco SB101 cable modem, Cisco PIX501 firewall, and 2 unmanaged switches. My goal was initially to add a wireless AP so that we would have wireless access (all our wireless devices would be 2.4g/n). However, I wasn't sure if I should add a router with built in wireless or buy a router and separate wireless AP. I initially thought about buying something like a WNDR3700 like I have at home, but I think we need better security given it is a medical practice. I'm open to suggestions please
