I need to set up a network in my office so I can have a company come and install software for me. They are going to setup my front office computer so I can perform normal tasks on it and it will function as an SQL server. But I need to have my other PCs connected to. I made two possible network maps and I am looking for any input or advice before I move forward. Any help is appreciated.
ISP-->Modem-->Network Switch-->WiFi Router & All PCs(Including SQL Server)
ISP-->Modem-->WiFi Router-->SQL Server PC-->Network Switch-->All other PCs
There are 6 Desktops total, and two WiFi laptops. Also, can the PC running the SQL Server operate with a wireless connection?
