  • I had the the same issue yesterday: no network after reboot, no blinking LED on the NIC, no network interfaces in the network settings.


    After changing the network cable and some failed attempts to start the network via serial connection I thougt the box is defective. So I checked if the box will receive an IP via DHCP in the rescue mode. The 1st attempt has failed, but on the 2nd one the box received an IP. After the reboot the NIC and (static) IP was also back in normal boot mode.


    So please try for serveral times if the box will receive an IP on bootup to the rescue mode.

  • this adapter will work: Edimax EU-4208 USB2.0/LAN adapter
    Chipset: Asix IC AX88772B


    you will find the necessary drivers for this chipset on http://sources.dreamboxupdate.com/ for your dreambox: kernel-module-asix (for ASIX AX8817X based USB 2.0 Ethernet Devices)


    after installing the driveres the adapter should be detected automaticly

    Code
    1. root@dm820:~# dmesg
    2. [177469.718000] asix 2-1:1.0: eth1: register 'asix' at usb-ehci_hcd-1, ASIX AX88772 USB 2.0 Ethernet, 00:50:b6:xx:xx:xx
    3. [177469.720000] usbcore: registered new interface driver asix
    4. [177470.485000] ADDRCONF(NETDEV_UP): eth1: link is not ready
    5. root@dm820:~#


    so you have to find an adapter with an ASIX AX8817X based chipset

  • thank you for your effort


    I found that the (Apple USB Ethernet Adapter A1277) working like charm after I had install


    kernel-module-asix as well as well as kernel-module-usbnet




    with following steps


    I install drivers on flash usb then connect it to dreambox


    mount the usb flash with


    mount /dev/sda1 /mnt
    cp kernel-module-usbnet_3.4-r1.13_mipsel.deb /tmp/


    cp kernel-module-asix_3.4-r1.13_mipsel.deb /tmp/



    cd /tmp



    dpkg -i kernel-module-usbnet_3.4-r1.13_mipsel.deb


    dpkg -i kernel-module-asix_3.4-r1.13_mipsel.deb
