(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.
Thank you for the in depth feedback, it is useful to me.
Without support for 4-address frames, you could use a routed (maybe
NATted) setup for your repeater.

In the same box? That is not likely to work well, if at all; the radios
will interfere with each other.
in your opinion Would it be better to use a amplifier and a splitter
to split the signial?
