i had not had issues with cm12.1 and wifi .. its since cm13 ... i updated now my Asus AC87u to the latest Beta.. i'll take a look... Its not only disconnecting during sleep.. its disconneting even when im surfing in internet
i dont know , if there is somewhere a lollipop Firmware for the TL10.
The update itselfe is easy. Put the File (Zip) on the Mate 7 , in the folder "dload"
Go in the settings of your Mate 7 -> Update -> choose local update
I got this Email from Huawei:
