I use usb wifi dongles that have AR9271 chipset and use compat driver 3.9.1 -
ath9k_htc. I use the wifi units to create an ad-hoc wlan.
When there is no communication for a while, the nodes leave the network and goes to sleeping mode. That cause a problem in case a node sends a UDP packet, the sleeping ones cannot receive it. they just rejoin the network in the first package and rejoining takes some time. Therefore I misses some messages to receive.
how can I disable that no node would leave the network no matter what?
For some reasons I looking for another method than
iw dev wlan0 set power_save off. It would be perfect if it is possible to do it via
wpa_supplicant (2.0) or anything else.
