The first time I had configured the Linux kernel, I felt there was an inadequacy because it did not have network support and I couldn't use the internet. I turned on the support in the following manner:
- First I removed the old installation of Linux kernel. On how to remove the old installation see here.
- Next I started the configuration by running 'make menuconfig'. For details on how to config Linux kernel, see here.
- When the config window opens up, go to Networking options. Enable TCP/IP networking. Enable 802.1Q/802.lad VLAN Support. Enable ANSI/IEEE 802.2 LLC type 2 support. Enable IEEE Std 802.15 Low Rate Wireless Personal Area Networks Support.
- Exit the config window.
- Build and install the kernel. For details look here.
- Reboot the system and check the running kernel using 'uname -r'.
