forgive the knowledge i have in this subject but i bought a pair of SXTsq 5ac access points and have them in bridged mode using 802.11 wpa2 no firewall rulls, mtu all the way to 2290 gains a 5 on each side. the rx tx strength displays at -41/-48 ccq %99/98. however i can only get 300 Mb/s in tcp mode. udp yields about 620 Mb/s.keep in mind thes antennas are only about 200ft away from each other. i would like to get higher tcp speeds? they advertised at 866Mb/s i expected at least 600 Mb/s tcp. what am i doing wrong?
