[Q] Anyway to get new Kernel with different MAC Address?

Can anyone help compile a new kernal to read the MAC address from the startup.txt or have a different value then 00:11:22:33:44:55? Or am I oversimplifying the issue... I have 3 HD2 for each of my family member and loaded Android onto them. However only 1 device can access the wifi at a time due to having the same MAC address. I have been trying for the past few days to learn git to download the source and compile the kernel but I was using windows and MAKE doesn't like windows too much. Any help would be appreciative, thank you.

This sounds like a great question. Does it occur on diff builds?

Yes, this occur on different builds. One is FroyoStone and the others are on darkstone v2.1.

i have it on mattc sense and i cant use wifi at school

There must be members who can point out the right direction to solve this very legitimate question. I'd like to know.
edit
Adding
Code:
set cmdline "WiFi.mac=XX:XX:XX:XX:XX:XX"
to startup.txt (where XX:XX:XX:XX:XX:XX is your own MAC found in WM) didn't make any impact, but I guest the OP already found that out.
/edit

it can be done, really easy actually..
in the script that turns on the wifi. all you have to do is before the wifi is turned on set the mac by ifconfig..
checking out the init.rc file i saw this
# wireless properties
setprop wifi.interface eth0
you might try to add under this
ifconfig eth0 down hw ether 00:00:00:00:00:01
then reboot..
i would do it but i dont have time for testing right now.. it might crash your phone
Edit, these files are located in the roofs.img
you have to mount it with linux to edit it.

Holy Thread Revival Batman!
Did you guys have any luck on working out how to change the MAC address? It would be fantastic to get it my real MAC back.

MTU value for stable wifi hotspot over RMNET with NAND builds.

Hello,
While RMNET connection of NAND roms are quite stable and seem as fast as SD build PPP connections, I seem to be having problems with wifi hotspot getting slower overtime. (as if it is getting bottlenecked) Wifi hotspot works quite fast initially. For example: You can feel the difference if you do a remote desktop session.
I opened up a terminal emulator and entered this command:
ip -s l l dev rmnet0
(l is lowercase L, not a pipe symbol, and make sure the spaces are correct)
and saw that MTU was set to 1500. (as it was ethernet default) But 3G data connection is not ethernet of course and AFAIK its default should be 1492.
so I entered this command to set the mtu to 1492
ifconfig rmnet0 mtu 1492
then connecting internet from my laptop through android wifi hotspot became much more stable over time. It seems it is not slowing overtime as bad anymore. Maybe since PCs have more processing power and makes a lot more connections than directly browsing through your phone, and incorrect mtu might be causing fragmentation and gets bottlenecked over time.
CAN YOU GUYS TEST THIS THEORY TO SEE IF 1492 MTU MAKES YOUR 3G DATA CONNECTION BETTER AND GIVE FEEDBACK? If it turns out good, future nand builds may incorporate 1492 MTU by default. Disable and enable your data connection as a precaution to make sure changes are applied.
Note: You can of course try lower than 1492 mtu if you want, which might make the connection slightly slower but better. Also you may try 1400. The change is not persistant with this command. (Returns to 1500 default after reboot) If this doesn't make any difference we may forget this thread ever existed. I don't see dropped packets even with MTU:1500 BTW. I am using Desire sense built by DFT.

thx a lot! it works fine for me

nice
bookmarked !

Changes are not persistent. (MTU is returned to 1500 after reboot)
I'll post a way to make it persistent.

Maybe edit build prop:
ro.ril.set.mtu1492 = 1

the buildprop line isn't working...
either i'm pretty sure the correct value should be 1472 ....
you can enter this command:
Code:
ifconfig rmnet0 mtu 1472;
in the init.d/99complete file on the end... then it should get set every boot...

Hello. Which file am I supposed to edit to insert the ifconfig command?
Running MDJ CM7 2.1 NAND CWM rom.
Forget it. Didn't know init.d was a folder in /system/ xD

I'm getting this error when trying to change the mtu..any ideas?

the 99complete is just a txt type file containing some additional commands, you could create a blank file and type it in there to make it stick on reboot I believe.
did you type "su" first also. maybe you need superuser access to change the mtu in terminal.
Chris

Yup..I tried with Su but got permission denied..I can't seem to even check my current mtu number..

This is quite interesting but I didn't manage to get the 99complete method working.
Did anyone get the change to persist after reboots?

CM6.1 wifi problem

I know this question is answered somewhere I just can't find it. I watched the you tube video on how to fix the wifi problem in the cm6.1 build but when I put the info into terminal emulator and reboot, it's not fixed. I enter the info just as it is in the info with the video, anyone else having problems?

I also had the same issue but I found the reason why. I actually used slightly modified versions of the commands via adb. The youtube video I referenced was:
http://www.youtube.com/watch?v=cvS4EvS0PAw
The commands I run were:
Code:
# rm -f /system/lib/modules/*
# cp -f /sdcard/hotfix/* /system/lib/modules
# chmod 755 /system/lib/modules/
I noticed that in order for this to work I had to do two things:
1.Make sure the Wifi is turned off before you run the commands.
2. Delete/Forget the Wifi Network that you attempted to connect to. Trying to reconnect with the same remembered network did not work. You have to delete it again.
Hope this helps.

[DEV] USB 3g for a500 wifi only

3g kernel module found here http://forum.xda-developers.com/showthread.php?t=1058713
ok i got 3g to work but small problem... internet works in console and in browser... any other app doesnt see the internet... I'm a linux kind of guy so maybe I'm missing something on the android part...
How to:
Code:
disable ZERO_CD on the 3g modem
put the modules from my other post in the root of /sdcard
put chat,ppp-start.sh,ppp-stop.sh in /system/xbin and give them execution permissions
go into /etc/ppp and make a directory "peers"
put 3g in the peers dir you just created
in console type:
su <enter>
ppp-start.sh <enter>
and done you should see the ppp0 interface
[B]PS: ttyUSB2 may need to be modified in 3g file depending on your modem...[/B]

added the archive i forgot to add sorry

Nice work
Glad to have a skilled developer here

Brilliant fix incidentally my Iconia is now 3G when needed!

Does this require Root?
This seems like a function that could require root, also does this work with any carriers or just certain carriers.
Amazing idea and cannot wait to see how it plays out. It would be really cool if eventually an app was made for this, unlocking this feature. Good job.

its limited to what the option driver can use(https://github.com/Tiamat-AOSP/Xoom....36-honeycomb-mr1/drivers/usb/serial/option.c) check first couple of lines you will find there devices with device id that works with this driver and also limited to modems with usb-serial interface, carriers dont play any role in this... only modems...

If I'm reading this, the USB 3G dongles will work in the Acer Iconia? Not being extremely tech savvy, I'm not sure if once you're rooted you can install these drivers and use it, or if it's still in development by the XDA Gods.
Could you clarify if this is working?

[SCRIPT] Change Hostname v6 08/07/2012

This will also be the last update to this script for the foreseeable future. Someone else is more than welcome to take what is here and run with it though.
08-07-2012 fixed a few typos and problems with quotes.
01-29-2012 added some variables to check for the existence of things and get correct paths.
01-06-2012 fixed hostname path.
01-02-2012 Updated to truly work on all devices.
Check it out and let me know what you think.
Big thanks to cdesai for pointing out a nice little enhancement.
This is version 5 of this script.
This script is designed to change the hostname of your device so that you can access it through your network by name instead of android_0123456789ABCEDF.
Your device will also be able to be seen at your router by the new name as well.
Code:
#!/system/bin/sh
#change devName to whatever you want.
devName="changeMe"
#random variables
devHostPath=$(which hostname)
devGetPath=$(which getprop)
devSetPath=$(which setprop)
if [ "$($devGetPath net.hostname)" = "$devName" ]
then
echo "Device hostname does not need to be changed."
else
echo "Device hostname is being changed to $devName."
$devHostPath $devName
$devSetPath net.hostname $devName
if [ "$($devGetPath net.hostname)" != "$devName" ]
then
echo "Device hostname has not been changed."
else
echo "Device hostname has been successfully changed."
fi
fi
Download Hostname.sh
Download Hostname.sh to your device.
Use a text editor to change the "changeMe" in the script to whatever you want. [Keep the quotes]
Use Script Manager to run the script.
The script output will tell you if the command has completed successfully.
Once it has been run your device will be named whatever you change the "changeMe" to.
*Additionally, this script should be able to be run on any device without issues but I have only tested this on Galaxy Nexus AOKP and Droid Bionic Eclipse v3.0.

Can anyone confirm this worked for them? Doesn't seem to be working for me.

What's the output when you run it?
And when you run it a second time?
You can check at your router as well by logging into it and checking the DHCP leases.
Oh, I figured this was assumed, but you have to have root and run it as root.

Yet another idea, you can specify the host name while executing the script as an argument (quick changes )
You can use read devname and if it's empty you can get model no. From build.prop

I left it static so that it can be run at boot and will always have the same name. The model could work but it is more for changing the name to something you want rather than being dictated what it will be.
Oh and depending on your model you could have a space or other special in it.

LG Revolution
On LG Revolution running GingerVolt 1.3, I had to change /bin/hostname to /system/xbin/hostname.
The script can be modified to determine the location of hostname command , rather than hardcoding the path.

I am working on a V5 of this which should be released within the next 2 weeks that should address almost all issues. It works as is on some devices but not all.
I have also found from my testing that setting the hostname is inconsequential and will only appear when you run the hostname command.

Thanks! This is the path on the Galaxy Nexus (ICS 4.02) and i was able to get it to update successfully.
However, if this does not update the host name that is sent to my wireless router, the point of the exercise is moot to me. But at least I learned a little bit more about my phone!

This has been posted elsewhere, but to set the name set for the Wifi DHCP request:
Code:
echo yourphonehostname > /proc/sys/kernel/hostname
Obviously, this needs root. You can stick that in a new or existing script in /etc/init.d.
No need to reboot the phone for this to take effect. Stop and start wifi to get the phone to request a new DHCP lease. Note that if your phone was already connected to a router, then the new name might not show up immediately. You'll need drop the previous name from the router dhcp client table by either waiting for the lease to expire, rebooting the router or expiring the lease manually (e.g., in Tomato Admin GUI, click on the remaining lease time under lease column in the Status -> Device List page.)
