Our company has 9 employees and probably 20 LAN jacks. We are looking for a more robust LAN solution. We have a single WAN connection through an Edgewater router. This goes to a single unmanaged switch. From the switch we have a DLINK wireless access point, and ethernet connections to everyone's office. In the offices are GigE switches and 8x8 VOIP phones. Occasionally we have a LAN network outage where no one can access anything on the LAN nor WAN. The solution has been to reboot the network gear until the problem is resolved. Is there a way to make the network more robust and or isolate the problems more effectively? If there is a problem with the network hardware in one office, I'd like it not to take down the whole company's network.
