If you are prompted that the network connection is restricted or there is no connection, you can operate as follows:

1. Open the computer "Control Panel", click "Network Connection", select Local Area Connection, and right-click Click the local area connection icon and select "Properties", double-click "Internet Protocol (TCP/IP)" in the "General" tab, select "Use the following IP address", fill in "192.168.0.1" in the IP address, and Fill in 255.255.255.0 in the netmask, no need to fill in the others, and then click "OK". It should be noted that the IP must be in the same network segment as the Modem’s IP address.

2. In addition, in the above steps, you can also remove the option "Notify me (M) when this connection is restricted or has no connection" in the "Properties" of "Local Area Connection".
