With NM disabled 2.6.25-wl  4311 after a suspend/resume I can:
1. Successfully scan for APs (ifconfig wlan0 up... iwlist wlan0 scan)
2. Associate with an AP  (iwconfig ...essid...key...)
3. Get a DHCP address (dhclient... offer... bound to address such and such)
but
4. NO FURTHER IP COMMUNICATIONS WORKS

Let me know what other diags to run or if I should upgrade to the latest 
wl tree if you think that will change the symptoms.
Things have been busy but there is a weekend coming up here shortly.
