View source for Using HSDPA modem

[[Category:Networking]]

== Requirements ==
This doc is tested on Alpine-2.1.3.

You will need a [http://en.wikipedia.org/wiki/High-Speed_Downlink_Packet_Access HSDPA] USB-modem.<BR>
Use 'dmesg | less' to figure out which /dev/ttyUSB? it uses ''(you'll need to edit the configuration shown below to reflect the correct port number)''.

== Install packages ==
Install  the required packages
{{cmd|apk add ppp}}

== Load modules ==
Now let's load the driver ''(using the values you just discovered)'' and configure Alpine to load it automatically at boot-up.
{{cmd|modprobe ppp_generic
echo "ppp_generic" >> /etc/modules-load.d/ppp.conf}}

== Configfiles ==

{{Note|Replace above word '''{PIN}''' with the "PIN" of your card ''(typically a 4 digit code)''}}
{{Note|Replace above word '''{APN}''' with the "Access Point Name" of the service you use ''(for instance mine is "web.omnitel.it")''. If you don't know the Internet APN, ask your service provider}}

== Routes ==
Create a default gw route to your 'ppp0' device.
{{cmd|ip route add default dev ppp0}}

== DNS ==
Figure out what DNS-servers your provider has.
{{cmd|egrep -i 'pppd.*dns' /var/log/messages}}
This might give you some useful information.<BR>
Search for a IP-address that might be your providers DNS-server and add this IP-address into '/etc/resolv.conf'.
{{cmd|echo "nameserver {DNS-server-IP-address}" > /etc/resolv.conf}}

= Start/Stop=
== Start connection ==
{{cmd|pon E220}}
== Stop connection ==
{{cmd|poff E220}}

= If something goes wrong... =
Check if process is running
{{cmd|pidof pppd}}
Logfile might give you a clue on what went wrong
{{cmd|egrep "pppd{{!}}chat" /var/log/messages}}
Check nic information
{{cmd|ifconfig ppp0}}
pppd has a statusinformation function that could come in handy
{{cmd|pppstats}}
