[ath9k-devel] AR9380-ath9k and hostapd based AP drops packets.

[Bhavesh Kamani <bhavesh.kamani@cyberoam.com>]

Hi Team,

I am using ath9k and hostapd to create AR9380 based AP.

I am able to observe more than 1% packet loss on cellphone 
clients(example android phone, android tablet, ipad, iphone, etc.). I am 
using 2.4 GHz band and I am able to observe this packet loss on any channel.

Can someone point me any parameter configuration change to reduce these 
drops?

ath9k version : backports-3.12.8-1
Hostapd version : hostapd 2.0
Hardware : AR9380 miniPCIe

Please find the hostapd.conf in the attachment.

Thanks,
Bhavesh.
