Said may work & it did ... lucked out
Have tried reboot several times this evening & it does not cease to work like some has reported (knock on wood).
With SSID broadcast disabled, NS still seems to see the SSID (Linksys WRT54G with latest firmware). Interesting ... other settings enabled on WRT54G are: 128bit WEP & MAC filter.
