A mobile broadband connection refers to the connection that uses a cellular network (GPRS / EDGE / 3G / 4G). This entry briefly introduces the configuration for setting up a mobile network.
Note: In later versions of deepin, the settings of mobile networks may not be accessible through the Control Center. Please try another network manager (for example, Gnome Network Manger) to do so.
Go to the Control Center -> Network -> Mobile broadband, and click to add a connection. The mandatory fields are:
Country / Region
Provider
Username
Password
The last two fields should be obtained from your service provider, or the manufacturer of the network card.
After save your configurations, click the name of the connection to activate it.
If the method above does not bring you a active connection, please check if the network card you brought supports Linux platform. If not, contact the seller or official support of the network card.
Deepin provides support of Huawei et127, without manual configuration by user. However, If the modem is not detected correctly, you may need to use usb-modeswitch and wvdial (or gnome-ppp, or the dial-up program that comes with your modem). usb-modeswitch is used to switch modes between the modem and the USB disk, and wvdial / gnome-ppp is used to set parameters for dial-up).
First deactivate the wired network (if any). You can execute in terminal:
sudo ifconfig eth0 down
where "eth0" is the name of the wired network card.
Get the local IP address of your modem:
sudo wvdial
Then set it as the default gateway.
sudo route add default gw 10.150.129.135
and restart networking service
sudo /etc/init.d/networking restart
To configure the DNS service for your modem, check the current DNS configuration:
ls -l /etc/resolv.conf
If this file is not linked to the file /run/resolvconf/resolv.conf, execute:
sudo rm /etc/resolv.conf
sudo ln -s /run/resolvconf/resolv.conf /etc/resolv.conf
Edit this file:
sudo gedit /etc/resolv.conf
and add IPs of name servers obtained from command sudo wvdial:
nameserver 221.130.33.60
nameserver 221.130.33.52
Then restart resolvconf and networking service:
sudo /etc/init.d/resolvconf restart
sudo /etc/init.d/networking restart
Now you should be able to reach the Internet. The next time when you need to connect to the mobile network, execute in terminal:
sudo wvdial # For dial-up
sudo ifconfig eth0 down # For bringing down the wired connection
sudo route add default gw x.x.x.x # For setting up the gateway
You may also need to run
sudo usb_modeswitch
first to make deepin accept the modem using a correct mode.
