Connecting to wireless internet validating identity

I am now trying to connect a friend's laptop, it is an ageing Toshiba Satellite M70-215 and from what I have been able to gather it is running Service Pack 2 and has only 512 MB RAM. First of all I tried to connect using the built-in wireless, even after updating the driver, no network is found. I also tried the option: Network And Internet -- Add a wireless device to the network but again nothing is found I downloaded this: and nothing seems to have changed. I tried to connect to the LAN using Ethernet (again after updating the driver), although I am apparently connected I can't reach the Internet and can't see what settings might need tweaking. I then tried installing the supplied Sitecom N adapter, after some problems the network appears but I can't connect, I am told "Windows was unable to find a certificate to log you onto the network" I read several threads that led me to uncheck "Enable IEEE 802.1x authentication for this network" and I actually managed to enter the WPA2 code but this just leads to the message "This connection has limited or no connectivity" and "validating identity". In any event I am finding that after rebooting the WPA2 code is no longer there and it has reverted back to Open WEP. Follow the instructions below to remove the network, then connect to it as a 'new' network. For more info see Delete a network connection in Windows 7 and Windows Server 2008 R2. Find the network on the list, right-click it, and select When the network connects and Windows asks what type of network, pick Public.

If you're familiar with wireless networks, the information in the "Summary" section is probably sufficient; if not, go to the Table of Contents below and find the section that matches your device's operating system.

If you're having trouble connecting to a wifi network, you can sometimes fix the problem by removing and re-adding that profile.

Removing ('forgetting') the profile and re-entering it seems to fix the problem.

WARNING: Most versions of Android Older versions do not directly support WPA2-Enterprise.
