    I flashed my two LG Motion yesterday and their wifi performance was incredibly slow. Spent a whole day to figure out what' going on. Turned out cm10 changed their mac addresses and now the mac addresses are same. If I turn one device offline then the other will have no wifi problem. But they can't connect to same router same time.

    Any fix idea?

    Yes I did.
    The mac address has been written in system/ect/firmware/wlan/prima/wcnss_qcom_wlan_nv.bin. Edit the file to assign a new mac address.

    Wow, thanks alot! I have been looking for days where it is stored and couldn't find it. What did you use to edit the file?

    Because the mac address is hexadecimal, a hex editor such as ultraedit can do it.

    Can't remember. You gotta find it yourself. Check your motion, get the mac, check with the file. It's in hexadecimal.

    Your file will have a line which is exact same with your current mac address. You have to view and edit it with a hex editor. That all I can help.

    Tried editing the file in hex editor app instead of on pc and worked! Thanks

    (There was no line with my mac when I copied the file to my pc and tried editing)

    I have the same issue except on CM11. The hex editor in the play store kept crashing. I managed to edit the file in windows but when I tried to replace the old file with the newly edited file, I got permission denied.

    Change permission in file explorer is easy.

    Yes I see. All I had to do was press the menu button and select root for ES File Explorer. New permissions allowed me to replace the file.
