How to connect to access point using VB.NET?

I have been searching the internet for weeks now.
Is there a way I can connect to a network/router/access point through VB.NET?
I don't really care if the program needs administrative privileges.
I have already made a program which lists the access points in range.
The purpose of my program is to, when in range of a BT Openzone or FON hotspot, to connect to it.
I am at the point where the program has found a access point in range.
Now, I am not that good with APIs, so please if you refer me to one can you give me more or less step by step instructions what to do with it (eg. put this file in the app directory, add a reference to this file)

Here is my current code:

Private Function RetrieveNetworks()
Dim proc As New Process
proc.StartInfo.CreateNoWindow = True
proc.StartInfo.FileName = "netsh"
proc.StartInfo.Arguments = "wlan show networks mode=ssid"
proc.StartInfo.RedirectStandardOutput = True
proc.StartInfo.UseShellExecute = False
proc.Start()
Return (proc.StandardOutput.ReadToEnd())
proc.WaitForExit()

I have managed to filter the output so I get a perfectly clean list of SSIDS.
Any help and I would be very grateful.
