I have been observing pretty bad behavior with a lot of 802.11ac access points around, (recently one that went 4Mbits over 40 feet through glass outdoors, but 600 indoors and 10 feet) but have nothing but guesses as to the causes. Infinite retries? Everything on 160 mhz wide channels? Has there been any good news or good tools lately? I pulled my ax200s out of the box and was going to see if there was any progress there. --=20 "For a successful technology, reality must take precedence over public relations, for Mother Nature cannot be fooled" - Richard Feynman dave@taht.net CTO, TekLibre, LLC Tel: 1-831-435-0729
