Hello All, I installed Centos 6.5 64 bit on a Dell Vostro 1550 laptop with i3 core. The kernel installed was 2.6.32-431.el6.x86_64. I was not able to compile kernel modules, even after installing the kernel headers, kernel source rpms. So I downloaded the kernel linux-3.10.31.tar.xz, extracted it, and did the following: make defconfig change CONFIG_USB_USBNET=y, in the .config. make ASIX AX88xxx Based USB 2.0 Ethernet Adapters (USB_NET_AX8817X) [Y/n/m/?] (NEW) n ASIX AX88179/178A USB 3.0/2.0 to Gigabit Ethernet (USB_NET_AX88179_178A) [Y/n/m/?] (NEW) n All the other options selected the default. make modules make modules_install make install Then I booted from 3.10 kernel, which went thru fine. After logging in into the 3.10 kernel, I compiled and insmod the asix driver for usb to ethernet. Upon insmod, the eth1 interface comes up, but with no IPV4 address assigned. So I assigned a static IP address using ifconfig. Then added a route for the default gateway. Now, after assigning a static IPV4 address, this eth1 is pinging to the default gateway 192.168.1.1. But eth1 is not pinging/connecting to the external internet. Can someone please provide some answers. I am using the device from www.svbinternational.com. The device is labeled USB 2.0 to network 10/100Mbps ethernet adapter. Device id, as can be seen from lsusb is: Device 003: ID 0b95:772b ASIX Electronics Corp. AX88772B. Thanks in advance.
