Hi folks, I bought a new mb GIGABYTE B650M AORUS ELITE AX ICE, placed cpu ryzen 7 7700 and gpu gtx 1060, no display when placed in gpu hdmi slot sometimes there is unless it is placed in mb one, so i upgrade the bios and did clear cmos and now lan mac address got wiped, it displays in bios Lan MAC Address N/A and ethernt slot not working anymore, could it be fixed if i installed a flushed bios with the mac address that i got from the motherboard ? i dont know if that is even possible. please help

how to find mac addresses

Open a command prompt and type:

arp -a

This will list all the IP and hardware (MAC) addresses that the PC knows of, which should be all the machines on the LAN.

 

Change Mac address

The MAC address is like your devices ID ,so short of being able to change very core settings ,you're not gonna be able to do anything unless I'm mistaken.

Maybe you don't need to change your MAC address, what is it you're trying to accomplish?

Spoiler: I found this change mac w/o root I can't say whether or not this is an effective method it's just a method I found after searching this topic .
I cant say whether or not it is "safe" or if the software required is free. use at your own risk.

Change MAC Address of Android Devices without Root Access

Go to Settings>About Phone>Select Status and then make a note of the current MAC Address of your Android device.
Download the Android Terminal Emulator application from the Google Play Store. You can directly navigate to the Android Terminal Emulator Google Play Store download page by clicking here.
Launch the above application on your Android device and then type “IP LINK SHOW”.
Note the interface name of your Android device from the list.
And then type in the command below,
ip link set interfacename XX:XX:XX:YY:YY:YY
Replace interfacename with the Interface Name of your network that you noted in Step 4 above and XX:XX:XX:YY:YY:YY with the MAC Address you wish to set.
And that’s it. The MAC Address of your Android device will now be modified/changed.

 

Network not work when identical MAC address in 2 device of 1 system

DavidYoung hi,

According to the description of you, your problem is that both devices use the same MAC address.Your network may not be working properly due to a MAC address conflict.

A MAC address conflict occurs when two devices have the same MAC address. This can cause confusion on the network because the router or switch does not know which device to send packets to.

In your case, your docking station USB LAN and laptop LAN have the same MAC address because they are both using MAPT. This means that when you connect the LAN cable to the docking station USB LAN RJ45 port, the router or switch does not know which device to send packets to.

One way to fix this problem is to disable MAPT on the docking station. This will cause your docking station USB LAN to be assigned its own MAC address, and the conflict will be eliminated.

The steps to disable MAPT will vary depending on the model of your docking station. However, the general steps are as follows:

1. Disconnect the docking station from your laptop.
   
2. Follow the instructions in your docking station's user manual to disable MAPT.
   
3. Reconnect the docking station to your laptop.
   

If disabling MAPT does not work, you may need to update the firmware on your docking station. Firmware updates can usually be downloaded from the docking station manufacturer's website.

If you're still having trouble, you may need to contact the hardware manufacturer of the device for further assistance.
