I saw a similar situation recently, a new laptop with an Intel AC chipset was sending continuous RTS at 2Mbps (on 2.4GHz), however the AP was configured with an 11g protection rate of 11Mbps. Setting that to 2Mbps and the client could talk fine. -- James Andrewartha Network & Projects Engineer Christ Church Grammar School Claremont, Western Australia Ph.
