No Wireless Extension found in iwconfig If we face issue if "no wireless extension found" for iwconfig, iwpriv, iwlist, etc. command when wifi module is connected to any ARM board with Linux. The solution for this is, By default, the wireless extensions are disabled, and users need to enable the CONFIG_WIRELESS=y, CONFIG_WIRELESS_EXT=y CONFIG_NET_RADIO option in the kernel configuration (this is the option which enables the choice of radio interfaces in the network driver list). Version magic Error while loading kernel modules We do get this error if the kernel module version doesn't matches with required version on host. You can find this version in a generated file after kernel configuration cat include/generated/utsrelease.h #define UTS_RELEASE "2.6.35.9-ARCH" This Macro gives the module version which we can edit to match to the required version of host kernel. Just edit this line then the version magic error will be avoided.
