Configure MODEM ZTE MF180 – Gentoo Linux

First, we type the command to configure our kernel with the options we need to use it.

 cd /usr/src/linux 
make menuconfig

Now, we need to configure IP & PPP support

Networking  --->
 Networking options  --->
  <*> Unix domain sockets
  [*] TCP/IP networking
Device Drivers  --->
 Network device support  --->
  [*] Network device support
  <*> PPP (point-to-point protocol) support
  <*>   PPP support for async serial ports
  <*>   PPP support for sync tty ports
  <*>   PPP Deflate compression
  <*>   PPP BSD-Compress compression

Now that we have marked all the options, we continue to the configuration for the support of our modem.

Device Drivers  --->
 SCSI device support  --->
  <*> SCSI CDROM support
 USB support  --->
  <*> Support for Host-side USB
  <*>   UHCI HCD (most Intel and VIA) support
  <*>   USB Mass Storage support
  USB Serial Converter support  --->
   <*> USB Serial Converter support
   <*>   USB driver for GSM and CDMA modems

Done, now, we proceed to compile our kernel with the new options and update it.

make && make modules_install
mount /boot (if we don't mount it everytime our system boots)
cp arch/x86/boot/bzImage /boot/linux-2.6.x.x

Done, now we reboot our system to log in with the updated kernel.

If the “Network-Manager” on Gnome, does not detects our Modem MF180, as root on a terminal, type:

 eject /dev/sr0
