Nexus 5x No Wifi. Default MAC 02-00-00-00-00-00 change attempt

So I bought new Nexus 5x with android 6.0 and everything worked fine, but when I updated to 7.1.2 suddenly wifi stoped working. (It seeks for wifi networks forever). When I go to settings I can see MAC adress which is default one 02:00:00:00:00:00. I've noticed that its common problem for phone like Nexus 5, 5x 6p and Pixels but all solutions I could find just failed. **What i have tried:** first simplest solutions they gave like pulling off SIM card, turning off phone, charging battery to 100%. - Failed Then i was trying to install other versions of Nougath 7, 7.1 , 7.1.2. Switching back to Android 6 makes wifi running again. Some people said that changing MAC adress resolved issue, so firstly I have rooted my phone. Then I have tried to use some external programs for changing MAC but they didint worked. **Problem** I am trying to change MAC manualy. I did it few times on other linux/windows machines with no issue. when i check for avalible network interfaces throught *ifconfig* it outputs bullhead:/ $ ifconfig rmnet_ipa0 Link encap:UNSPEC UP RUNNING MTU:2000 Metric:1 RX packets:843 errors:0 dropped:0 overruns:0 frame:0 TX packets:1129 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:563887 TX bytes:210944 dummy0 Link encap:UNSPEC inet6 addr: fe80::78e6:16ff:fe96:3cf7/64 Scope: Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 TX bytes:210 rmnet_data0 Link encap:UNSPEC inet addr:10.156.9.217 Mask:255.255.255.252 inet6 addr: fe80::53e3:f4d7:6ca9:be5e/64 Scope: Link UP RUNNING MTU:1500 Metric:1 RX packets:843 errors:0 dropped:0 overruns:0 frame:0 TX packets:1129 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:568878 TX bytes:210944 lo Link encap:UNSPEC inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope: Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 TX bytes:0 there is no *eth0* interface nor *wlan0*. All of those interfaces does not have mac assigned. As I have tested *rmnet_ipa0* and *rmnet_data0* are probably for mobile connection (ifconfig (rm..) down makes mobile connection off. So my question is how do I find network interface for wifi so I can try digging in it. Thanks!
