I just took over a small office network that has some issues. Heres the current setup:
cable modem connects to sonicwall firewall that has a static ip of 192.168.5.39, sonicwall connects to a 24port switch, switch then connects to a dlink router set at 192.168.0.1 with the gateway pointing to the sonicwall. Then the other 4 24port switches are fed by the router. In addition we have a wireless router set as an access point. The problem is that different workstations around the office keep losing connectivity. I can reboot the router firewall and it clears up for a an hour or so then starts dropping connection again. What could be causing this? and better yet how can I fix it?
