Home networks and Gigabit switches

Figure 48 shows the network devices connected to a Gigabit switch, which in turn is connected to a WiFi
access point. Based on extensive experience with our professional systems, we found that not all Gigabit
switches worked reliably in our application. We now find that the vast majority of Gigabit switches currently
available will work without problems.

Details of Gigabit switches that Merging has tested and found to work properly:
