Simply put, we have switched a small office of about 12 PC's, a server, and a couple of printers from one service to Comcast. We have no static IP addresses set up with Comcast and we only have the Comcast cable modem as our router. I know that this is not good but it is where we are right now. We have our own domain. Logins take about 4 minutes now which is way too long. I figure that either I need to buy a router and set up the cable modem to be only a modem or that I need to buy some static IP addresses from Comcast in order to solve the problem. Until then, is there anything I can do right now to improve performance?
