Ubuntu Mac Address Hide I Switched From Windows To Ubuntu, And Need To Access My Wireless Router. Anyone Know How?

I switched from Windows to Ubuntu, and need to access my wireless router. Anyone know how? - ubuntu mac address hide

The reason is that I create my Nintendo DS, by its MAC address to the Allow list. I am using a Linksys WRT150N and the DS does not say anything about this on their website. If your answer is linked to his support, calling Linksys - Air-Hack IP address or the fact that I know because he told me that if I stand it, do not respond. Your response is useless for me, common and annoying. Someone knows what to do ?
