So you still have to type 'adb push bcmdhd. Then just hold shift and right click a random spot inside the folder and select the option 'Open Command Window Here' That starts your cmd operation right from the location you need, rather than ever having to type ' /users/*Youre comps username*/Desktop/' I really hope this helps (Note that doing the mentioned short cut I use does not mean you only type 'adb push bcmdhd.ko' You still need to tell cmd what location to push the file too. I moved all my adb files to the same folder as my bcmdhb.ko and any other phone related file boot.img's, ect.

Starting with Vista, for a WiFi interface, the Type field will be IFTYPEIEEE80211 You can also identify dial-up ( MIBIFTYPEPPP) connections and loopback ( MIBIFTYPELOOPBACK) virtual interfaces. (see screenshot below) 3 Click/tap on the network connection you want to see the MAC address for. 2 Click/tap on the Change adapter settings link on the left side. *** What I do to save time and extra typing. 1 That code you have for querying MAC addresses, also fetches the interface type. To Find MAC Address in Network Connection Details 1 Open the Control Panel (icons view), and click/tap on the Network and Sharing Center icon. Now using cmd and adb type the command 'adb push /users/*username*/Desktop/bcmdhd.ko /system/lib/modules' (Minus quotes, *username*= user name of computer) If you're using a Mac, Windows PC, an Android smartphone or an iPhone, your device is assigned a unique media access control (MAC) address from the factory. (You'll need root access and a root file explorer) Download the appropriate file for your phone, boot your phone into recovery/fastboot and plug into your computer. Try finding and replacing the file named bcmdhb.ko located in System>lib>modules. Turns out the problem was as simple as a faulty file in the Android system. My wifi always said 'Turning on' but never did, and my mac address showed 'Unavailable' I too had the same issue after I flashed a new kernel to my HTC Vivid.

I made an account on this website just so I could share what I've learned on this subject that I think might help.

What is my wifi mac address
