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

[Bhavesh Kamani]

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.

It could be power save. Maybe the AP is dropping frames to the client.

Are you able to setup another AR9380 in monitor mode and sniff the
hostap traffic? That way you can see what goes out into the air and
what is acked.
