Hi all, I am not trained in networks but know enough to be dangerous and I'm afraid I have been. I was told to setup a basic network for my company and fear that it is now the cause of devices randomly dropping off the network each day. Here is the setup, Comcast business class cable modem connected to Netgear WNDR4000 wireless router connected to an 8-port Netgear GS608 switch. This switch connects to 7 different areas of the office and in each of those 7 areas is another switch providing network ports to the devices in each of those 7 areas. 6 of the areas are offices with just 1 to 4 devices in each and each of the 6 office areas has a single Netgear GS608 switch providing the network ports. The 7th area is a shop floor which has about 25 devices connected to 3 more GS608 switches and a single Netgear GS116 16-port switch. There are no direct connections anywhere that go back to the wireless router. I hope you can understand the setup from my description. This network has evolved and has needed to grow because the company has grown and more and more switches have been thrown on to accommodate more devices, not to mention that all network hardware is SOHO type. I have suggested that we wire the building for all direct connections back to a single switch but not sure if the company will agree with the cost. I have also recommended that we upgrade the hardware to business class Cisco type network equipment. Can you make suggestions for a stable network based on what I have explained here, and please remember that I am not a trained network technician. I don't know how to diagnose where the actual problem is coming from. One more important note is that there are a mix of PC's, Macs and other devices on the network and a NAS drive which has ALL our files on it. Thank you so much!
