I installed Elastix 1.2 on a laptop with usb nic (Moschip mcs7830) but I don't know how to install the nic drivers, I have downloaded the drivers and extracted but don't know what to do next. here is info from usb nic. lsusb -> Bus 001 Device 002: ID 9710:7830 MosChip Semiconductor and extracted files are: Makefile, mcs7830.c, mcs7830.h, mosinstall, mosuninstall, readme and couple release notes. I was able to use Saleh instruction for an on-board Realtech nic for another person with a bit of modification but the last command runs to snag, here is his instruction # tar vjxf r8101-1.009.00.tar.bz2 # cd r8101-1.009.00 # make clean modules (as root or with sudo) # make install # depmod -a # insmod ./src/r8101.ko You can check whether the driver is loaded by using following commands. # lsmod | grep r8101 # ifconfig -a after # make install I received error message: mcs7830: unknown symbol generic_mii_ioctl insmod: error inserting '/lib/modules/2.6.18-53.1.19.e15/kernel/drivers/usb/serial/moschip/mcs7830.ko': -1 Unknown symbol in module when I run lsmod | grep mcs7830 here is the result mcs7830 23056 0 mii 9409 1 and when I ran ifconfig -a now I see usb0 Link encap:Ethernet HW 00:13:...... but no ip address.
