(802.11 implements it's own ACK scheme to correct errors below the upper protocols - without this TCP performance over wireless would be terrible. If the signal is poor or suffering from interference, you'll see latency i.e. ping times increase rather than having immediate packet loss). No, there's no space for enough addresses in the standard 3-address frame format used by 802.11 (the "WDS" frame format adds another address). You need to have the link-layer addresses of the source and destination, as well as the transmitting and receiving wireless node so that 802.11 ACKs can be sent to the right place. Without support for 4-address frames, you could use a routed (maybe NATted) setup for your repeater. > is there some way I can put 6 PCI cards in one AP and use a Bridge > command to emulate WDS In the same box? That is not likely to work well, if at all; the radios will interfere with each other.
