I have a small dental office with a small network of Windows 7 (32-bit) computers. In total there are 4 workstations. One of the workstations is a wireless laptop and the other three are directly wired into a router (each about 25 feet apart in different rooms). In addition to the workstations, I have 3 wireless printers and a wired in Western Digital MyBookWorld external drive connected to the router.My router is a Belkin Wireless Play Router (F7D4302). Also worth mentioning is that my internet service provider is Comcast/Xfinity cable. Each of the workstations has dental office management software that accesses data which is stored on the MyBookWorld external hard drive. This is the life force of the practice – the data going back and forth between the hard drive and the workstations. My problem is that the connection speed seems quite slow when reading and writing data to and from the workstations. I do not want to make any changes to the actual workstations. How can I boost the read/write and data transfer speed to my workstations? If I need to reconfigure my setup or upgrade my router or external drive, or internet provider - I am up for that. Please help.
