The method for using cdma wireless Internet access in linux-Linux general technology-Linux technology and application information. The following is a detailed description. I'm glad I finally got online. Step:
Dmesg | grep tty check whether your wireless network adapter is identified.
[8.518726] 00: 0a: ttyS0 at I/O 0x3f8 (irq = 4) is a NS16550A
[2, 8.559342] hash matches device tty
[26.492000] ttyS2: detected caps 00000700 shocould be 00000100
[26.492000] 0.0: ttyS2 at I/O 0x3e8 (irq = 3) is a 16C950/954
The last one is my wireless network card. Remember to check whether ttyS2 or ttyS1 is ttyS3.
Then
Sudo ln-sf/dev/ttyS1/dev/modem maps your wireless network adapter to your modem. There should be no response. Note that ttyS1 should be the seat of your wireless network card. Do not make a mistake.
Then
Sudo gedit/etc/wvdial. conf she will open a text editor
Then overwrite the following content to the file.
