I think it is a good solution that share the Internet connection from the
USB modem to the WiFi connection on the laptop.
Some steps need do:
Step 1:
Power your USB modem, and connect it to your computer. Make sure your internet connection is OK.
Step 2:
Use an ethernet cable to connect your computer and iPad.
Step 3:
Start ->Control Panel ->Network Connections .
Step 4: Right click â€USB modems Internet connection.†-> properties -> “Advanced†-> Select “Allow other users to Connect through this computers internet connectionâ€.
Step 5:
Maybe you will get a info that says you need to redial your internet connection. Do these:
“Network settings†->â€Settings†->â€Internet Connection Settings", and click X. Select the easy setting, and from there it should detect your IP Address, and clarify an internet connection from your pc to your iPad. Save these settings.
