WHEN  you have a windows vista wifi connection saying "local only" please read ;

try restarting the router and or wifi hotspot, & stop using WPA-2 AES encryption 
in fact untill you CAN CONNECT TO THE INTRNET AT ALL stop using ANY security  

vista might be shutting down the wifi,, make vista leave the wifi card on by clicking 
[start] [settings] [control pannel] [Power Options] [WirelessAdapterSettings] [Power Saving Mode]
 = MaximumPerformance


but most of the time this is caused by  2 regestry settings  in the key 
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{subkey}

DhcpConnDisableBcastFlagToggle = 1
and
DhcpConnForceBroadcastFlag = 0

You want to apply the change to any subkey found.

1. [Start] [run] [regedit.exe] 
2. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
3. {GUID} sub-key refers to the network adapter that is having the issue.
4. Add a new DWORD (32bit) value and rename it to DhcpConnDisableBcastFlagToggle.
5. Modify the DhcpConnDisableBcastFlagToggle key and change the value to 1?.
6. Modify the DhcpConnForceBroadcastFlag key and change the value to 0?.
7. reboot retry and if that fails

change the preferred DNS server,  right click the wifi icon [connect to a network] right click on your wireless network 
 and select;  [status] [activity] [properties] [WirelessNetworkConnectionProperties] window [Networking] highlight [IPv4] 
 select [Properties]  In the [InternetProtocolVersion4(TCP/IPv4)properties] window  
 select the [Alternate Configuration] select [User Configured] 
 fill in the top 4 lines with the correct information for your network.  and make sure of
 [preferred DNS server] VISTA does not capture it unless you fill it in  Then OK your way out.
 reboot, retry web and if that fails 

Disable IPv6 & reboot, retry web and if that fails 

[start] [programs] [accesories] right click [cmd] "run as administrator" and type all of the following 
 ipconfig /flushdns
 netsh winsock reset catalog
 netsh int ipv4 reset reset.log
 netsh int ipv6 reset reset.log
 netsh interface tcp set global autotuninglevel=disabled 
netsh interface ipv6 set privacy state=disabled
netsh interface ipv6 6to4 set state state=disabled
netsh interface ipv6 isatap set state state=disabled
