Mungkin ini udah banyak yang tau , tapi menurut pengalamanku ketika beli kemarin tutorial yang beredar di internet banyak yang aku coba dan gak berhasil. akhirnya aku posting aja di blog kesayanganku yang sudah lama gak aku kunjungi dan aku rawat ini.

Langkah awal nya adalah melakukan tes apakah modem Venus VT 12 dengan chipset Huawei ini dapat terdeteksi di linux.

ketikkan perintah  lsusb lalu akan keluar seperti dibawah ini

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 003: ID 12d1:1001 Huawei Technologies Co., Ltd. E620 USB Modem
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 003: ID 0408:20ba Quanta Computer, Inc.
Bus 001 Device 002: ID 0bda:0158 Realtek Semiconductor Corp. Mass Stroage Device
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Diatas adalah hasil ketika modem sudah dikenali oleh linux dengan nama Huawei E620

lalu anda harus menginstall wvdial

apt-get install wvdial

setelah itu anda edit settingan wvdial di /etc/wvdial.conf

gedit /etc/wvdial.conf

[Dialer Default]
Init1 = ATZ
Init2 = ATQ0
Init3 = AT+ CSQ?
Init4 = ATQO V1 E1 S0=0 &C1 &D2 +FCLASS=0

Selanjutnya anda ganti settingan ppp anda

gedit /etc/ppp/options

# Set the MRU [Maximum Receive Unit] value to <n> for negotiation.  pppd
# will ask the peer to send packets of no more than <n> bytes. The
# minimum MRU value is 128.  The default MRU value is 1500.  A value of
# 296 is recommended for slow links (40 bytes for TCP/IP header + 256
# bytes of data).
#mru 542
mru 296

Setelah anda melakukan settingan tersebut , silahkan anda melakukan dial dengan perintah

wvdial default

jika anda mendapatkan ip dan dns maka anda berhasil melakukan koneksi dengan modem vt 12 di linux.
