Huawei EG162G (Idea netsetter)

Introduction

The HUAWEI EG162G is a EDGE/GPRS modem used for wireless internet access. The current kernel (2.6.29.4) has support for this device and thus setting this up isnt very hard

Plug it in

Plug in the device , wait for a few seconds and then run

$ ls /dev/ttyUSB*

you will see something like this: /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3 the first one is the port of the modem.

Installation

Now install wvdial which is a dialer

# pacman -S wvdial

or if you dont have ppp install that too

# pacman -S wvdial ppp

Configure and dial

Edit your /etc/wvdial.conf and use this if you are using an idea netsetter , else use google to find the right config for your provider

[Dialer Defaults]
Modem=/dev/ttyUSB1
Baud = 460800
Init 1 = AT+CGMM
Init 2 = AT+CMEE=1
Init 3 = ATE0
Init 4 = AT^HS=0,0
Init 5 = AT+CFUN?
Init 6 = AT+CLCK="SC",2
Init 7 = AT+CPIN?
Init 8 = AT+CLCK="SC",2
Modem Type = USB MODEM
Phone=*99#
Username = idea
Password = idea
Dial Command=ATDT
Stupid Mode=1
ISDN=0

Remember that the modem might get a different port each time you plug it in so you might need to change the 'Modem=/dev/ttyUSB1' each time, for example if the output of $ ls /dev/ttyUSB* is /dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2, then you need to change the 2nd line in the wvdial config to 'Modem=/dev/ttyUSB0'

now all you need to do is run wvdial as root

# wvdial

if you get an error 16 in wvdial it means that there is no modem present in the port specified by the config, so edit your config file accordingly

if the connection is successfull you will see something like this:

Note: if you get an error 16 in wvdial it means that there is no modem present in the port specified by the config, so edit your config file accordingly

but you still wont be able to surf the net unless you have a nameserver in ur resolv.conf. if you dont have a nameserver in your resolv.conf then edit /etc/resolv.conf and add this line to it nameserver 208.67.222.222

If you are already conected to a lan then change the subnet mask of the lan to 255.0.0.0 and you should be able to use the lan and the netsetter
