Vista Net share quit after conneting to new wireless

I recently bought a new laptop with Vista loaded. I cleaned the hard drive
and did a clean install of Vista Ultimate and all worked well.

I could see my 10 other computers and 2 servers in my home office network
which has multiple OS with a wireless and wired network:
XP Pro
2000 Pro
Server 2003
Ubuntu - Linux
MAC 9

I could get to all of the shared drives on each machine. I could not get to
My Vista laptop shared docs but I could resolve that later. I could also RDP
to my computers also from the laptop.

I took my laptop to a computer lab I have at our chuch for them and the
public. I have a WPA wireless network. When I connected to the wireless
network it asked me if I wanted to do public or private. I was being asked
questions by 2 people during and did not fully read the options.

I selected "Private" and connected to the internet without a problem (so I
thought).

When I returned to my home office network I could not see any of the above
computers or connect to them. I can ping them by name and connect to the
internet.

I have the settings at:
"Private network"
All are in the same workgroup name "LCHOME"
Network Discovery = On
File sharing = On
Public folder sharing = On (Turn on sharing so anyone with network access
can open, change, and create files)
Printer sharing = Off
Password protected sharing = On
Media sharing = Off

I can connect to the internet and RDP currently.

Thanks in advance.
