I didn't read the entire thread, but generally when you see a low TX
like that on Ubiquiti and the RSSI indicates it should be stronger it's
an ACK issue, specifically too short of an ack calculation. Make sure
you are using a fixed ACK on those, and that it is set high enough to
cover the distance.

Nope. Crawling as it has been since Tuesday afternoon. 6.5Mbps tx is
sloooow. Got some sleep so going back now. Any & all ideas are welcome!
