When this tutorial was created, I used the **BackTrack** distribution. And it should work on other **Linux** distributions too.
|
|
|
|
First, you need to [download `usb_modeswitch`](https://www.draisberghof.de/usb_modeswitch/#download). If you already have an internet connection (with **Wi-Fi**, for example), you can simply run the `wget` command:
|
|
|
|
```bash
|
|
wget https://www.draisberghof.de/usb_modeswitch/usb_modeswitch-1.0.2.tar.bz2
|
|
```
|
|
|
|
After the download process is complete, extract `usb_modeswitch-1.0.2.tar.bz2`, which you just downloaded.
|
|
|
|
```bash
|
|
tar -xjf usb_modeswitch-1.0.2.tar.bz2
|
|
```
|
|
|
|
Go to the `usb_modeswitch-1.0.2` directory and install:
|
|
|
|
```bash
|
|
cd usb_modeswitch-1.0.2; sudo make install
|
|
```
|
|
|
|
and you will get output similar like this:
|
|
|
|
```plain
|
|
[sudo] password for ditatompel:
|
|
mkdir -p /usr/sbin
|
|
install ./usb_modeswitch /usr/sbin
|
|
mkdir -p /etc
|
|
install ./usb_modeswitch.conf /etc
|
|
```
|
|
|
|
It can be seen that two files have been installed: `usb_modeswitch` and `usb_modeswitch.conf`. Edit `usb_modeswitch.conf`, which is located in the `/etc` directory.
|
|
|
|
```bash
|
|
sudo nano /etc/usb_modeswitch.conf
|
|
```
|
|
|
|
Add the following configuration, which is similar to **ZTE AC2710** (**EVDO**) modem configurations by **Wasim Baig**:
|
|
|
|
```plain
|
|
#########################################################
|
|
## ZTE AC2726i (EVDO)
|
|
DefaultVendor= 0x19d2
|
|
DefaultProduct= 0xfff5
|
|
TargetVendor= 0x19d2
|
|
TargetProduct= 0xfff1
|
|
MessageContent= "5553424312345678c00000008000069f010000000000000000000000000000"
|
|
```
|
|
|
|
Then, open the `wvdial` configuration in `/etc/wvdial.conf` and edit the configuration file:
|
|
|
|
> _\* I recommend always backing up your configuration before making changes._
|
|
|
|
```bash
|
|
sudo nano /etc/wvdial.conf
|
|
```
|
|
|
|
Add the following configuration:
|
|
|
|
```plain
|
|
[Dialer smart]
|
|
Init1 = ATZ
|
|
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
|
|
Modem Type = USB Modem
|
|
ISDN = 0
|
|
New PPPD = yes
|
|
Phone = #777
|
|
Modem = /dev/ttyUSB0
|
|
Username = smart
|
|
Password = smart
|
|
FlowControl = CRTSCTS
|
|
Carrier Check = No
|
|
Baud = 9600
|
|
```
|
|
|
|
The `usb_modeswitch` and `wvdial` configuration has been completed.
|
|
|
|
Run `usb_modeswitch` from the terminal to change the USB modem product from `fff5` to `fff1`.
|
|
|
|
```bash
|
|
usb_modeswitch
|
|
```
|
|
|
|
Then, the next step we need to do is detect the **product ID** of the modem we are using:
|
|
|
|
```bash
|
|
sudo modprobe usbserial vendor=0x19d2 product=0xfff1
|
|
```
|
|
|
|
Finally, run the `wvdial` command:
|
|
|
|
```bash
|
|
sudo wvdial smart
|
|
```
|
