Toshiba realtek wifi drops connection

My Toshiba Satellite Pro L300 PSLB1E VISTA BUSINESS drops the wifi connection in 4 or 5 minutes after the computer has started. This thing just started a few weeks ago, it worked always fine. After searching the Internet for simular problems i replaced the driver realtek rtl8187b. Power Saving on networkcard is set OFF.
If you switch modus "powersaving" in Devicemanager/Realtek from CAM to FAST_PSP or  MAX_PSP the networkcard is working for another 5 minutes. I even reinstalled Vista but the problem is still there.
It is not a router problem, i cheked it with 3 different brands. The bios is the latest version for this machine.
Other Toshiba notebooks that i have are working fine here. Any suggestions are welcome, i am considering a downgrade to XPPRO, i believe there is a conflict between the realtekdriver and vista.

Is this an "on-board" adapter? Did you upgrade the driver from from Toshiba or directly from Realtek? If from Toshiba then try: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=1&PFid=1&Level=6&Conn=5&DownTypeID=3&GetDown=false&Downloads=true#RTL8187B

As it did work perfectly a couple of weeks ago, then I reckon it may be a hardware fault with the device. Downgrading to XP won't fix it. If the laptop is still covered by warranty then take it back, if not, you can buy a USB wireless ethernet adapter for 20-30 Euros.

Both suggestions didn't work. I downgraded from Vista Business to XPPRO with a clean install. The wireless works now with no connectivity loss at all.
