Toshiba L350 Internet Problem

[Moggy6]

I have a Satellite L350-12N Laptop, and I have just had to re-install Vista due to a problem, the LAN cable connection works fine, but I have had problems finding Wireless Lan Drivers and the only one that installed, when I had an unknown device in device manager was the Realtek 8187 Wireless software from Toshiba web site Intel drivers did not work.

The problem I find is once installed it will log on to my un-secure Belkin Ni Router and internet is fine, if I restart laptop it will not log on even though it sees the router on connect to a network and there is no way it will connect unless I un-install and re-install, I am at a loss as to a cure for this problem, the only cure is to put a dongle into the USB port, I was going to try a PCMCIA card but the slot on the side of the Laptop is for a card with a much smaller connector at the end.
If I enable security I have the same problem it will not log in to the Wireless.

Can anyone assist in a cure for this problem
