Vista wireless cannot resume connection after sleeping mode

I bought a Dell inspiron with Vista 3 months ago. Since then I cannot connect to wireless connection after hibernation or sleeping mode. I had to restart in order to reconnect. Recently it got worse and the only resolution is to unplug the cable and router for 10 seconds.

I called Dell wireless suport to resolve this frustrating issue. She tried changing power option to maximize network performance during battery charging or not charging. She also check my network card and uninstall, reinstall driver.

it took her 2 hours and she couldn’t resolve this issue. She had to escalate to level 2 support team and will call me 7AM tomorrow because she only works from 12AM to 9AM daily. 

 I personally tried ipconfig/release/renew, disable/enable network connection, uninstall ip6 and none of them seems working.

Worse case is I will roll back to Windows XP. Most of the software doesn’t support Vista anyway.

disable User Account Control in Vista

There is this sucker in Vista that pop up when you click on anything and it will ask for permission to access.
I guess Microsoft products had been cracked for countless times. That’s the reason Microsoft applies security on every little thing.
To turn off this default security.

Control Panel->user account->turn off Account control on or off->uncheck use uac to help protect your computer.
Click OK and restart.

 Updated: WARNING! the setting above screwed internet explorer. I cannot delete any yahoo mail nor compose email, i cannot log in to certain sites. This is weird. I am going to roll it back and live with it for now. 

 Updated: I found out that disable UAC using the way mention above will cause your IE not to run in protected mode and your system will be less secure.

This will be second way of disabling UAC

1. Run “secpol.msc”
2. Expand “Local Policies” and click “Security Options”
3. Scroll down to the item User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode
4. Set it to “Elevate without prompting

 Another way to run as a super user.
