Created attachment 2528 [details] patch to fix The current code in edca-txop-n.cc, upon a MissedCts () and MissedAck () condition, checks if an A-MPDU exists (and later, whether a block ack association exists) before sending a Block Ack Request to advance the left edge of the reordering buffer window. However, it can be the case that the current packet is not part of an A-MPDU, nor later packets, in which case the Block Ack Request is never sent and later packets are not delivered (i.e. the reordering buffer blocks on the sequence number gap). A small patch can enable the sending of the block ack request in this case.
