I have a wireless network set up with the above computers on a cable
connection through Cox Communications. DHCP from the router is
disabled and all three computers have static IPs. The SSID broadcast
is also disabled. WEP security is enabled.

The wired desktop and wireless laptop have no connection issues at all.
Despite the SSID being hidden, the laptop has had no problems
continually accessing the network over the past 3 weeks. This morning
I switched the Sony from wired to wireless and have had nothing but
problems with it. I verified all the settings with the laptop (IP,
DNS, etc.), but could not access the network with the Sony. After
alternating between the Linksys network monitor and Windows Wireless
Zero Configuration, I finally enabled the SSID broadcast. This allowed
me to connect to the network and the Internet (via Firefox/IE), but I
receive the message "You are connected to the acess point, but the
Internet cannot be found." in the Linksys monitor. The big issues is
that I cannot access the Internet/streams from Winamp, Windows Media
Player, iTunes, etc. Also, if I disable the SSID broadcast - even
after saving all the settings using the Linksys monitor - I immediately
lose the connection and cannot reconnect until I enable the SSID
broadcast. Firewalls are not the problem.

Any suggestions would be appreciated. Have been fighting this all day
and don't know exactly how to proceed (other than wiring the Sony to
the router again).
