[OpenWrt-Devel] [PATCH] Hostapd: wait longer for inactive client probe (empty data frame)

[Dmitry Ivanov]

Hostapd: wait longer for inactive client probe (empty data frame).

One second is not enough for some devices to ackowledge null data frame
which is sent at the end of ap_max_inactivity interval. In particular,
this causes severe Wi-Fi instability with Apple iPhone which may take
up to 3 seconds to respond.
