WiFi on laptop has problems when laptop goes into sleep

So lets say I boot up my laptop for a powered off state. Once the laptop gets into windows it will automatically connect to my saved WiFi network and everything will work normally for as long as the computer stays on. Once I close the laptop and it goes to sleep I start having problems. When I turn my laptop back on from a sleep state, either the WiFi wont be working from the start or it will work for a little while and then cut out. Either the laptop will not automatically connect to the saved network and it wont be able to see any local networks, or it will connect but it will constantly connect and disconnect. The only way to fix this and get it to automatically connect and stay connected is to reboot the laptop. Sometimes going into the my network connections and disabling and enabling the wifi adapter will fix the problem and sometimes it wont.

The laptop is a Dell XPS 1530 running Vista Ultimate x86 with a Dell G/N WiFi adapter.

This problem happens at my house on my Dell DRG-4500 N router and at my girlfriends house on her SBC 2WIRE router. Im convinced that t is not a signal problem. At my house we have an HP laptop running XP downstairs that never has signal problems and at my g/f house she has a Powerbook that never loses signal.
 
I had the same problem on a Studio 15 laptop...I had to go into device manager and uncheck the 'allow windows to turn off this device to save power' on the properties of the wifi nic.

- I also got rid of the Dell wifi app and used Windows and it seemed to connect faster from sleep/standby
 
My fiancee has the same issue with her Compaq. I didn't think about looking at the "allow windows to turn off the device to save power". I'll give that a shot too.
 
My wife had that problem and that was basically the fix. Vista is just like XP and the Server 2003/2008...it's got an "administrative tools" menu in control panel/system and maintenance . If you go in there, you can bring up services and show whether or not your wireless network services are still running. Should be in the services list under WLAN or something similar. See if that's still in the 'started' state when you lose connectivity and see if restarting it from there fixes the problem without restarting. That might be where the hardware is being controlled from to save power.
 
Just to add an update to this;

I did exactly what DrGreen said; I went into the devices properties and unchecked "allow windows to turn this device off to save power". After about a weeks worth of use I have had zero problems with the WiFi adapter, thanks again!
 
Yeah my gf's mom had this issue with her Inspiron 6000. Basically she couldn't be in battery mode and log onto her VPN via wireless. This was the fix.
