If all above fails: Yes, flashing a ROM would solve the issue as well - as this ROM should contain the necessary files. If you have at least an image available for your current ROM, you could extract it from there as well. There are several reasons why the MAC address may be corrupted, so we will try to address each one until your issue is resolved. Having a similar device available running the very same ROM, you could extract the binary from there (the config as well, or course). The Solution First try this very simple solution: Settings -> Backup and Reset -> Reset Network settings -> Reset If that did not work, we will need to get a bit more technical, so follow me closely. If the binary was removed, options are narrow without a backup. Still, recovery from that should not be too hard: there are not too many different interface names, and other settings (like the chipset used) can be taken from specifications - so root provided (which is the case, or you could not have deleted it), you could re-create a matching file with a little try-and-err. This would also explain the missing MAC address: no known device, no known MAC address. If the system-config file gets lost, the binary does not now where to look for the interface, as that's configured here (e.g. Of course, all your saved networks would be lost - but that's a minor issue compared to the others: So if the latter config was deleted, it simply would be re-created after a boot.

Furthermore, this file memorizes those networks you've connected to, including SSID, encryption used, and the passwords, all in plain text - that's where those 'WiFi password recovery' apps get their information from

It repeats some of the contents from the system file (most likely copied from there on initialization - as /data gets completely wiped on a factory reset, those things must come from somewhere), but skips the comments. /data/misc/wifi/wpa_nf is located in the writable part.

/system/etc/wifi/wpa_nf is the default configuration (as the path correctly suggests, in the read-only /system area), which also includes device-specific settings, plus some 'inline documentation' in form of comments.

/system/bin/wpa_supplicant is a binary (i.e.

There are three corresponding files on Android: a passphrase or username and password) and add it to the preference list to enable automatic reconnection in the future.ДЄs it is said: curiosity killed the cat - and deleting wpa_supplicant makes it quite impossible to use WiFi. Review a list of currently visible networks, select one of them, provide any additional security information needed to authenticate with the network (e.g. In addition to being a full-featured WPA2 supplicant, it also implements WPA and older wireless LAN security protocols. Wikipedia can offer a little insight on what that means:

Once you've found an available IP address, you can change your Android device's IP address.As it turns out, the problem was caused by deleting wpa_supplicant. 12.3.4.7 and so on, until you find an available IP. If you don't see any IP addresses showing 'Destination host unreachable,' repeat the ping command with the next sequential IP address, i.e.

If any IP address appears with the text 'Destination host unreachable,' that IP address is available. Press the Enter key when you are finished.ДҐ. Using this example, your ping command should look like this: ping 12.3.4.6 For example, if your Default Gateway is 12.3.4.5 the next sequential IP address would be 12.3.4.6. To find an available IP address, type the 'ping' command followed by the next sequential IP address following your Default Gateway. The DNS Servers are two servers related to your internet service provider and internet usage.Д¤. Look for the information called 'Default Gateway,' 'IPv4 Address,' and 'DNS Servers.' The Default Gateway is your network's IP address, while the IPv4 Address is the IP address of the computer you're typing commands from.

In the Command Prompt, type the following command and then press Enter:ДЈ. You can find the Command Prompt in any version of Windows.Дў.
