I can understand the bad reviews at all. I have integrated the network hub in the network and almost everything worked. First, of course you have the Mac address if a Mac is used filters, are entered in the router. In Mac 10.5 and 10.6 program runs as immediately and you just have to allow the outbound connection. (LAN and WLAN test) On Windows Vista, the integration is a bit tricky, which is why some have probably made a bad rating here. The printer or the hard disk is recognized but can not be connected. For this purpose insert just the 19540 port in the firewall with TCP and UTP and the connection permit it works. The only drawbacks I noticed are in fact the lame data transmission of 4 Mb / s and that the connection only works when the PC is directly connected to the router. This means that if behind the router with the Belkin connected again Wireless router is connected and so the PC, then a connection can not. Otherwise, really a great device. It will also work hard disks unpowered, as has been wrongly criticized. Who connect up to 15 USB devices do not always directly on your PC or Mac will do well with the Belkin is.
