If you are willing to build NM from source you can modify it in
src/dhcp-manager/nm-dhcp-manager.c

#define NM_DHCP_TIMEOUT		45	/* DHCP timeout, in seconds */

You probably also want to increase your association in
src/nm-device-802-11-wireless.c

#define NM_SUPPLICANT_TIMEOUT	20	/* how long we wait for
wpa_supplicant to associate (in seconds) */

However this doesn't solve the root problem and if you don't have the
ability to move the AP or your laptop have you considered using
different antenna's on the AP or increasing the power level?   Making
the changes I listed above /might/ allow you to associate but you will
drop A LOT and you will probably find it more frustrating than useful.


Just to make sure, you don't have an Atheros card do you?
