Problems Connecting Optus Wireless Broardband (OWB) using HUAEI E220 - 720: Error Network might need changing ...
After spending hours trying to repair my newly connected OWB connection I thought I would document the method which worked to stop the annoying Error message 720: Error Network ...
The scenario was that one day I had problems connecting to OWB using the HUAWEI E220 modem. I rang helpdesk an they read these instructions out to me for an XP laptop
This installs the TCP/IP protocol on the modem. Apparently when I unistalled the modem and reinstalled it didn't install the TCP/IP protocol for some reason.
