[Dnsmasq-discuss] dnsmasq problem: nokia cell phone does not accept dhcp offer

Hello,

I am trying to connect a nokia cell phone to my home wifi network. The
same phone has reportedly worked properly on another home wifi network
which has a Belkin wireless router. The phone is set to acquire an IP
address automatically, i.e. via dhcp.

BTW, my home wifi network is provided by a wireless card in a machine
running Debian Testing and 2.6.26-2-686 kernel. The cars is D-Link
DWL-G520 working in ap mode and has WPA encryption enabled.

The wireless is network provided by hostapd using madwifi driver.
Windows and Mac machines work properly with this wifi network (at least
no big problems noted, certainly not in Windows clients).

When I try to get the Nokia phone to connect to the wifi network, I get
these lines in my dnsmasq log (to see lines without wrapping, here is
the pastebin link for convenience - http://pastebin.com/m466c8fd2):

---------------------------------------------------------------

Anybody know the problem might be?

If I switch off dnsmasq dhcp queries logging, i.e. if I decrease the verbosity
of the log, all I see are two lines of DHCPDISCOVER(ath0) and
DHCPOFFER(ath0) repeatedly in the log with no acceptance by the cell
phone.

It appears as though the phone is not accepting the dhcp offer.

However, if I give the phone a static IP address in its configuration,
it works properly on the wifi network. So it appears as though the
problem is dhcp related.

Hints? Suggestions?

Installed stuff:
$> dpkg -l *dnsmasq* hostap* | grep ^i
ii  dnsmasq       2.50-1  A small caching DNS proxy and DHCP/TFTP server
ii  dnsmasq-base  2.50-1  A small caching DNS proxy and DHCP/TFTP server
ii  hostapd       1:0.6.9-3  user space IEEE 802.11 AP and IEEE 802.1X/WPA/

Thanks.
