Test 1: Two computers directly connected to the router via 100 Mbps Ethernet: Transfer Rate 100 Mbps.
Test 2: Data transfer via PA4010 and WPA4220 (buy as a set) in the same room: Transfer Rate 50 Mbps.
That's enough time just for DSL. I am very disappointed with the performance. Therefore, only one point. Since only 50 of 500 Mbps arrive, would actually 1/2 point more than adequate.
