Dear Maintainer,

I am using hostapd to occasionally provide wifi from my Debian
system. It works as expected after a regular boot process. It
doesn't work anymore after waking the system from suspend: E.g. my
phone sees the wifi and starts to connect, but it looks like no DHCP
is provided.

Doing "/etc/init.d/hostapd restart" helps. Maybe you could add a
wakeup routine for this?

Thanks for your work.

Michael

Which wlan chipset are you using?

It might also depend on the particular kernel module you're using,
although I haven't tested suspending a system with an active hostapd
process so far (bad intersection of suspendable vs hostapd compatible
wlan cards over here).

Please also add a dmesg log from a system that has gone through one
suspend/ wakeup cycle with a running hostapd as well, feel free to
mail that one privately, if it contains potentially sensitive
information.

According to lsusb:

ID 07d1:3c03 D-Link System AirPlus G DWL-G122 Wireless Adapter(rev.C1)
[Ralink RT2571W]

The relevant modules are probably:

rt73usb                22341  0
rt2x00usb              17687  1 rt73usb
rt2x00lib              38480  2 rt73usb,rt2x00usb
mac80211              371723  2 rt2x00lib,rt2x00usb
cfg80211              352039  2 mac80211,rt2x00lib

The kernel is version 3.8-1-amd64 (from experimental)

I will send it separately, as I don't know whats in there.

Cheers

The problem is still there with the current kernel 3.9.8-1 from testing.
