Hi Ashiq

1. How can I make *C* to communicate with only one* AP* at any particular

In code connecting WifiNetDevice and L3Protocol, ensure that a packet is
forwarded up to L3Protocol only if the sending STA is associated with the
AP.

2. How can I get perfect association in ndnSIM? Currently, C sends

It is normal for WiFi association to take some time because it needs a few
packet round-trips. The consumer application/forwarder is responsible for
retransmitting lost packets.

Yours, Junxiao
