content: I bought this DP-311U print server. I set it up according to the manual and i can print from different computers to the printer. However, a few hours later, it stopped working. I disconnect then reconnect everything, it started to work again. But a few hours later this same thing happened again. I called the tech people at D-link and started to explain the problem when the line was disconnected. I thought this must be an accident. I called again. After transfering to a different number and waited for about 10 minutes, i was just about to describe the problem again, the line was droped again. I checked my telephone lines, they were ok. D-link's tech support is just a waste of time. By the way, i have other similar products which work fine.Mike
