yes,It seems M&M's rom have this problem
Here is what I find
First of all, M&M's rom just need one file to fix wifi issue,juse ar6000.ko (wifi.ko is exectly same as ar6000.ko file)
and by replace ar6000.ko with rootexplorer,wifi works perfect before reboot
but, after reboot , wifi goer wrong again,and if replace ar6000.ko again,then WiFi work fine, but after reboot, error get back
so, the problem happen during system reboot.
and I manuly get FC the force reboot the system then WiFi still works fine.
It seems system replace ra6000.ko file(243kb) to original ra6000.ko(263kb) everytime system shut down.
so the problem is where is the original ra6000.ko file come from(we already replace the current one),it may have some backup in system?
hope this could help~
after all,you did a great work championswimmer
best regards
