Hi All After inclusion of the stack and drivers in the mainline kernel for 2.6.29, there have been some changes that affect the WiMAX Network Service. For making the current release (1.3.3) work with the mainline driver, a patch has to be applied. Detailed instructions are available in http://linuxwimax.org/WiMAX-Network-Service-1.3.3-mainline-README.txt Future releases will have this limitation removed. Thanks, -- Inaky
