I have a wireless network with a linksys router (four computers - 1 is wired
to router, three are wireless). When SSID Broadcast is on, everything works
fine. When I turn it off, one of my three wireless computers (call it #3)
can not detect the network, even though it is listed as a preferred network
on computer #3. As soon as I turn SSID broadcast back on, it reconnects
immediately.

Any thoughts as to why this is happening?

Thank you,
Len
