I routinely get this error for just a couple of clients on my AP-and they often get disconnected as a result. Updating the firmware/driver on these clients is not an option (proprietary systems) and a carrier busy test shows I'm fine. After much searching though, I found the âpacket retries 128 drop-packetâ command at http://www.cisco.com/en/US/products/hw/wireless/ps4555/products_qanda_item09186a0080094cdc.shtml and this has resolved the issue. My question is, does anyone know the pros and cons of using this command? I'm assuming there must be some cons to this magic command or Cisco would have made it the default.
