Say I need a little help:

I use a HTC Phone to tethering my MacBook Pro & iPad 2, I use the MacBook Pro as a 'hub' and I connect the iPad 2 via 'WI-FI" to the MacBook Pro, no problem, I am trying to connect a PC laptop with Windows 7 OS also via the MacBook Pro.

The wifi signal shows on the PC laptop (*********MacBook Pro), but when I try to connect gives me errors, "Windows was unable to connect to ********MacBook Pro".

Any suggestion are welcome and Thanks

I can use the iPad and iPhone 4S with not problem, but not the PC Laptop.
