... it was easy to install HH4 on PCs ....
Uh? A CD?
You are obviously clueless about the HH4.
While on auto the Hub and wireless PC automatically connect and updates connection security to match wps or wep if former not supported. Saves time with manually typing of code and getting it wrong.
There is security to stop unauthorised access on auto.
Once all machines updated just log into hub and set to manual.
As the password of ISP is your TN number. Plug in HH4 and go.
No CD
