MAC Address 02:00:00:00:00:00

[masi79]

After updated to Lineage 17.1 i am facing problems with Wifi. In Lineage 17.1 everything works fine (except wifi-calling and volte). When flashing back to Stock (via Oreo-RUU or TWRP Restore) i don't get any wifi-connection. If turning on wifi, system turns off immediately. In settings I found, that mac address is 02:00:00:00:00:00... searching this problem, i found out, that this problem happened often via update from android 5 -> 6. Flashing Stock ROMs didn't help, restore of prior LeeDroid Backup neither.

Did anybody face this problem in former times? Does anybody know where MAC is stored / what the problem may be?

I am experiencing the exact same issue. Same MAC address, same wifi issue. I tried flashing to stock Oreo, same issue. I'm going to try flashing stock Nougat, but I have doubts about that working. I also tried clean flashing the RR-P 7.0.2 ROM, and the same issue happens there too. I could not fin a way to restore the MAC address. I was able to look up the original address from my router's device log . . .

My HTC is the US T-Mobile version. @Golv can you help us with this new issue?

-UPDATE-
So far, going to stock Nougat INSTANTLY works. Right on the setup menus, all the wifi networks show up. Odd how stock Oreo gave us issues, but Nougat didn't. Will be going to RR-P 7.0.2 and seeing if the fix sticks I removed the SIM card when I put the phone back to Nouagt BTW if that affects anything.

-UPDATE 2-
Flashed stock Oreo after flashing Nougat, and in the setup menus, the wifi networks are showing up in STOCK OREO. Still with SIM removed. Now to flash the RR-P rom and see if I'm all set.

-FINAL UPDATE-
Flashed RR-P 7.0.2. Everything is back to normal.

Thank you very much! I checked whether the sim card has an effect, removed it and flashed Stock Oreo -> problem still exists. Then i flashed Nougat an experienced the same effect: Wifi worked right on the setup menu.

@Golv do you have any idea why this happens? I think, this problem should affect anybody, who wants to go back to prior versions.

I believe it is related to the hosd_signed.img file that likely writes over the persist partition. By downgrading, we are overwriting the hosd and the nougat ruu then formats and rewrites a new MAC address. It was interesting to see this happening, but I'm glad I found a workaround.

Sorry for the delay in reply. For some reason notifications stopped coming to me ...
Most likely you should change Mac address setting from random to device’s Mac address before switching to stock (Settings - Network - Wifi - Network details - Advanced - Privacy - USE DEVICE MAC).
