Why can t the smartphone turn on the wifi?

You should be wifi hardware driver abnormal,I also use me860,Nickname A4,It's a licensed product,Just look for the beast,Find a seller for parallel online shopping,Or brush yourself (this machine is slightly risky to flash for the first time,Need to unlock Shenma,It's troublesome,No experience in flashing operation,Treat it carefully) It should be your rom has a problem,I don't know if you will flash the machine third-party,It's a card brush,(I use the ancient city after unlocking,The big bag is very stable,Brush for almost a year, the total number of crashes is only ten times, It's really stable,Jifeng Forum,Find me860 section,Find the corresponding flashing tool yourself,Tutorial,If you want the ancient city package, you leave a q,I'll give you the link when I go online),It's not good to only brush the bottom package,This needs to be unlocked,The same goes for the first time card brush (because the card brush is very safe,And it's convenient when to jump off,Memory card carryback,Direct engineering mode can be brushed) There is no third-party flashing software that needs to be unlocked by brushing the bottom package,So this mobile phone is easy to become bricked for the first time flashers, Be cautious!!

Is it flashing? If so, it's your problem with flashing the package. If you don't flash the machine, see if you have obtained root access to delete something and delete the file by mistake.

If it really doesn't work, restore the original factory settings to see if it can solve the problem, I hope it can help you! Is it flashing? If so, find a stable ROM package to brush down, I guess it's your bag's problem.
