Can I change my Hero's ID on a wireless network?

My Hero ID shows up on my wireless network as UNKNOWN, is there a way to change this? I know there was in WinMo, but I can't find anything in Android.
Thanks.

Do you mean the hostname?
I've not tried it but try setting it in /etc/hostname, and add it to the end of the localhost line in /etc/hosts, might work..

Hi Sam, thanks for the reply. Not sure what you mean by hostname.
I'm referring to how the phone is identified on a wireless network. With my WinMo devices I gave the phone a name in the Device ID section. Then, when I go to my router, I am able to see IP address, Device Name, and MAC address.
I cannot find any settings in the Hero that allow me to specify a device name, so it always shows up as UNKNOWN on the network.

Linux / unix
Deke
a Hosts file is a file that links IP address with Names... Windows have them UNIX and macs... etc...
its a file you will rarely see in windows. but in unix/linux you very well could.. as Android is based on Linux i beleive the sugesstion mentioned is to edit this file on your phone and ad the Local host (the phone itself) in there with the name you want it to have...
In UNIX (which i use) i can totaly see this working but have no idea if this will work on the phone, and you will need it to be 'rooted'
this means have access to the Administrators privlages to edit files...
(in linux root = Administrator)
there are posts on the forums on how to root your phone and it will open up function to you but at the same time will allow you to happly **** up the system files if you dont know what your doing and make your phone into a nice paperweight...
hope this helps

Hi Bobro; very helpful, thanks.
So basically I can't do something as simple as give my phone a useful ID without rooting it? I would regard that as a fundamental requirement, so it seems a bit foolish to omit the functionality from Android.

gtablet Device name on the network

Does anyone know how to change the device name on the gtablet? I now have the ablilty to hook me gtablet up to my corporate network, so I went into the DHCP server to make a reservation for the device the name that it displays is andoid_XXXXXXXXXXXXXXXXX.mydomain.com replace the X with Hex numbers and letters. I would like to change the name on the device so that other admins know what the device is and don't delete if from the reservation pool.
i was thinking
IpadCrusher.mydomin.com

I too would like to know how to change the hostname (device name).

I still like Viper Tablet for the Viewsonic VEGAn build when ever it goes final!

I would also like to know. I keep getting hassled by my Network Admins because every time I load a new ROM, the "xxxxx" changes and it looks like a new device. Same thing happens with my HTC Incredible Phone.

I'm jealous because I can't even logon to my works corporate network. Device keeps failing to assign an i.p address.
I get connected via wifi if I assign a static address, but android doesn't support http proxy or something, so the username/logon screen never comes up

If you are rooted and have a robust busybox installed, after reboot you could execute the following command:
busybox hostname YourDevice
You could setup a gscript script and run it before you turn on your wifi or download autostart and have your script run automatically after a reboot.

Your network admins actually allow this thing on your corporate network?? Oh my.

In Linux, the computer name is stored in the /etc/hosts file. You might try editing your hosts file and put in:
127.0.0.2 name.site name

If you get a fixed IP address or one with reservation each time you connect to your wifi router, this may work.
I have a home built dd-wrt wireless distribution system at home and was playing with the hosts file to see how my wds interpreted hosts file and it didn't work but that is just my homegrown system. my 2wire router didn't interpret it either (gave the random android_xxxxxxxxxxx device name.
Of course, you could just give them the MAC address of your wireless card which you can get by doing #busybox ifconfig in a terminal session and tell them the name you want and they can create an Arec in the dns names.

Actually, no. However, connecting to MS Exchange with Sync logs the Device ID into Exchange. So, each time I load a different ROM, I log a new ID. Drives them nuts.
I did some research today though and found an app called Android ID Changerthat will allow me to see my DeviceID and modify it. I reinstalled my orginal ROM, recorded the ID, reloaded Vegan and changed the ID to the original device information. Works very well.

I found this post in another forum that may work for you:
http://forum.xda-developers.com/showpost.php?p=9560696&postcount=1
Please note that if you do use setprop you would have to reset it after each reboot. I think adding a correlating line in build.prop (if one exists) would be a better alternative. Otherwise, they discuss unpacking/repacking the boot.img to make it permanent.

I wouldn't say its on the corprate network, its on the corprate wireless network, I can get to the web and the intranet but that is about it we have it pretty locked down. I have it teathered to my phone most of the day. Its fun to take it to a meeting and have all of the iPad users say is that the new iPad I just laugh and think YOU WISH.
Roebeet I know I have talked about this before with you, I like you would like to get my usb air card working on this bad boy that would solve all fo my connections issues. Im not the smartest guy with linux but I could spend some time if I could find some info about it.
I had found this site a while ago but could not get the drivers to install I'm sure its because we don't have source code.

[SOLVED]School Wifi, Two IPs

I've been looking around the forums and google for a solution to this. From what I found, the solution that works for most people with the same problem as me ends up being chnaging the UA String to iPhone or Desktop, but that still doesnt seem to work for me.
Now my problem is that at my school, they set it up to where you have to log into a portal before you can access to the WiFi, but my phone never redirects to the portal. It used to on Windows mobile, but now running Android on NAND, it wont redirect. I've tried nearly every browser on the Android market, tried changing the UA String on all of them. And still nothing. I ended up going to the school's IT Dept, and they registered the Mac Address to my phone, but then told me that my phone was connecting to two different IPs. One being the school IP, the other an unknown IP.
I've looked in the WiFi settings and i cannot find this second IP they gave me. From the sound of it, thats my problem. Any idea on how to remove this second IP? Or if the IT dept. was wrong? If so, and other ideas on how I can connect to this portal?
PS: My phone connects to every other portal website i've gone to so far, except the schools.

hmm strange, normally your WIFI connection connects to only one network. You can find the IP address by calling *#4636#*#* then Wifi Information / Wi-fi Status. Now click Refresh and you'll see your connection info. You can even run a ping test

Not sure if I am reading that right, but the USB Port can have an IP? If thats possible, how can I disable it or change it?

You need update your ROM to one that support unique MAC address or search WIFI MAC to set the MAC address back to your real one. Old Android library on HD2 set the MAC address by using a file so all the phone has a same MAC address by default. You didn't have two IP address. There is someone else running a Android HD2 on the network. Two devices with the same MAC is the same device to the IT Dept. Only one of the device will be routed at any one time.

This sounds like it might work. I'm currently art school an unable to change roms. I'll do this when I get home and leave an update.

No need to change rom.
Use search function 'change MAC adress' or something like that.
I'm using a SD Android and needed to change it also, was just a change in startup.txt.
Maybe it is a little different in NAND? But it should be easier to search a little bit around as to re-flash.
(Most or maybe all Android builds have this problem)
If possible, use your WM MAC adress to avoid further problems.

I ended up changing my rom, and it fixed my problem. Used Hyperdroid GBX, also gave me a chance to install CWM.
But your fix might have worked as well.

His fix will only have worked for sd builds, not NAND. currently, many kernels for nand will give you a unique mac address, but there is no way to set it like there was on sd builds

MAC Address Spoofing

Being overly paranoid I'm always trying to make it harder for companies to track my device. Anyway, my most recent discovery is spoofing the MAC Address on my 3T so that wifi companies can't track it.
*** This requires root ***
I have it working in Marshmallow 6.0.1 (not tried it in Nougat)
Only attempt this if you understand MAC Addresses and be sure to note down your original/official MAC Address. Open /persist/wlan_mac.bin and take a copy of the contents before attempting the below.
Some background reading if you're not familiar with MAC Addresses.
Code:
ifconfig wlan0
will tell you all you need to know about the current state of your wireless adapter
The first command generates a MAC Address. I've hardcoded the first 6 characters of mine and randomly generate the remaining 6. It should generate a perfectly valid address but please post if it doesn't (or you have a better bash line).
The second sed command is to replace the MAC Address in the persisted wlan file. It's this command that needs to run as root.
You should be able to run these in something like Termux (make sure you're running as root by running "su" first). I actually run them using Tasker as "Code/Run Shell" commands.
Finally you need to enable then disable Airplane Mode for the change to take affect.
Here are the commands:
Code:
MAC=C0EEFB$(od -txC -An -N3 /dev/random| tr -d ' ')
Code:
sed -i "/Intf0MacAddress=/c\Intf0MacAddress=${MAC}" /persist/wlan_mac.bin
Code:
settings put global airplane_mode_on 1; am broadcast -a android.intent.action.AIRPLANE_MODE --ez state true
Code:
settings put global airplane_mode_on 0; am broadcast -a android.intent.action.AIRPLANE_MODE --ez state false
Code:
ifconfig wlan0 | grep HWaddr

Why don't you write a shell script that saves the old mac address to a text file and then create the new one. And each time the user executes the shell script to spoof the mac address it appends to the existing log file in a new line the old mac address before changed again. That was if you ever need to revert it, you can look at the log file.
BTW, thanks for the share!

using a custom mac address
Newbie here. Just wondering how I could use a specific mac address instead of a random generated number.
Thanks in advance.

Yeah definitely things to improve,automating storing the original being one of them. I'll maybe follow up with that.
I didn't want to mask the main two commands too much with others around them. There are a few (older) ways to do this but this was the only way I could get it to work. And it's not a complete app/solution, more teaching a man to fish sort of thing.

You can although
a) OP3T isn't listed as a supported device, I didn't try it
b) You can't automate it with that app very easily. Mine changes via Tasker state/events every day so I don't need to bother doing it myself.

Easiest way is just to change the first command and hardcode the MAC you want, ie
Code:
MAC=C0EEFB998877

Termux says
Sh: MAC: Not Found after running second command. Any idea what went wrong?

Ah oops, that's an error in me typing it out. The 2nd command should contain:
Code:
${MAC}
The brackets were causing it to try and evaluate MAC as a command (rather than a variable). I'll update the OP.

I can confirm this works. many thanks!!

Android is using randomized MAC adress when searching for wifi networks, this is not needed.

As of 6.0 it was my understanding that Android uses a generated MAC for scanning/probing networks. But when actually making a connection, the real MAC is used (so as not to cause network issues). So this post is still relevant. I'm generating a new MAC every day or two as I use a number of public open wifi connections.
Also working on my hostname being random, and trying to stop all traffic on an open wifi network until my vpn is up.
Some might argue it's OTT, but I'd say it's just good practise (certainly the last point).

Well, if you are concerned about your safety, don't connect to any Wi-Fi / BT devices that you don't trust.

The MAC address spoofing is more about privacy in terms of trying to be anonymous, making it *harder* to track where I connect etc...
Trust is a slightly more complex, non-binary issue.

MAC aadress is only used in local network, it does not go further than the very network you are connected to. What kind of advantage does MAC spoofing give you?
There's still your device ID, browser information and other stuff, that can actually reach the service you are connecting to.

It stops wifi services tracking my phone. For example I use the wifi on the London Underground. Every time I connect to their wifi they'd know exactly where, when, how long, possibly my DNS requests just based on my MAC. It's all information that can be used for profiling or sold on (if that was part of the terms). They still may not known who I am exactly, but I'd rather they weren't able to identify/target me if it meant simply randomising my MAC. As mentioned Android already does this when scanning for networks.
Device Id isn't given, unless you mean hostname (which can be randomised too). If you're using HTTPS based websites then all browser traffic is encrypted via SSL. If you're not, then yeah it's possible to packet sniff your traffic (which is illegal), see what you're browsing, what your browser is, even part (but not all I believe) of your MAC etc...

Try Pry-Fi
Chainfire already has Pry-Fi for that. It has worked flawlessly for me.

first of all thank you for the commands but somehow this does not work with my Oneplus 3 (without T) on Sultans CM13. The address does not change after entering the commands, the commands do not show any error message.
Any advice?
Furthermore Pry-Fi seems to be able to change the MAC but it crashes sometimes and it seems to loose my saved WiFis. Furthermore i am not able to connect to my home AP after changing the MAC with Pry Fi. :-/

Many public, free hotspots that require accepting terms on "walled garden" page today are tracking MAC address, DHCP-assigned IP address, and DHCP lease and active session time stamps. Example hotspots include Starbucks, hotels, etc. These hotspot network operator have logs to trace IPs back to MACs at a specific point in time until the logs are disposed.

changing mac address rooted phone

I have rooted phone with Resurrection remix on it. I have an Iptv provider and it's on my android box.
In order for it to work on phone I need to have the same mac address.
I can see how to change mac but does it affect the phone in any way ie WiFi connections etc

That's kind of illegal when you spoof Mac adresses to gain access to restricted services you don't want to pay twice

Have you tried Mac changer app? I think there was one that needed xpoosed not sure though.
Theres plenty of ways to change a Mac. If you want you can just go into file explorer and change it there have you tried that?

Thanks
I'm okay changing it I just want to know if effects anything else on the phone like WiFi password access or password etc
Cheers

Changing the layer 2 adress always effects the whole communication since you have a new one. Therefore any devices which communicate with the device needs to learn this new adress(happens automatically normally).
If you have some Mac adress security in devices like access points, soho routers etc. you need to change the Mac there too, otherwise you will be blocked.
But passwords not. If you do something wrong, you can mess up your phone.

Thanks
Just want to make sure that my home network WiFi will still connect automatically or do I need to login WiFi password again

Just be careful, because you can have major issues if your android box and phone are on the same network. The router/switch will potentially route packets to the wrong device, making network access slow and/or unstable.
