You should probably tell which custom ROM you have been installed to experience this.

First i tried aicp and then aex...
If i installed custom rom then its having one mac wifi address even though changing another custom rom its having the same wifi mac address.
After switching into stock rom it had another wifi mac address
All custom rom having same wifi mac address
Stock rom having different wifi mac address

we are using a different mechanism to store MAC address
in custom rom, we will generate a new MAC address and store it at /persist partition
meanwhile at stock rom, it's not stored a /persist partition
it's somewhere we didn't know
so whatever u flash stock > custom rom and vice versa
your phone will have a new generated MAC Address

Router crashing with new Jelly Time rom

Hey guys,
I tried searching and could not find a similar problem.
Since getting the new rom I have noticed that my wireless router has been experiencing connection issues. all my devices show connectivity but i dont have access to the net. Anyways i decided to have a look and the android is creating multiple Ip entries on the router with the same mac address and everytime I turn the wifi off on my phone the problem does not occur.
Any ideas?
Thanks

Have you tried going into development settings and turning of Android Debugging or ADB over network? Just a suggestion, not sure if it will work.

nah cant be that, I had them turned off already.
Thanks for replying anyway. I searched google and its a pretty common problem with no concrete solution, might need to flash the rom again.

Why don't you try binding the MAC Address to a static IP so it's no longer able to create multiple entries on the DHCP Table?
tjturko13 - have you tested to use another standard 802.11 Modus - instead "n"? Just switch it at your phone or router.
What router do you have? Can you update the firmware? ^^

i dont think my router allows this, the only option I have is to specify if I want to allow mac filtering.
Have checked out my last post about the wlan-standard?
I found also another thread about a member with wifi problems after updating his rom. He didnt flash the new boot.img - but dont know if it was the solution.

thanks ill check out that thread,

its a isp provided cablel router that does not let me mess around with FW but i have checked and it seems to have the latest FW
where do i get the boot.img file from?
Did you get your new rom over the air? (Stock rom)
Or did you flash a custom rom?
You have to give us more software informations about your rom. Is your device s-on or s-off?
Stock rom you need the right RUU exe file. Just doubleclick - yes yes yes
Custom rom you need to download the custom boot.img.

There is an update available. I saw another post of an user with wifi-problems. He flashed the update and the problems were solved.
I've also noticed, that the wifi might have some problems with some channels as you can see here:
Broken:
bluetooth - works in beta 7. Broken in beta 8 +
Working:
Wifi Tethering
camera - not perfect still buggy
Mic
accelerometer
audio
bluetooth
wifi - may not support some channels
hw acceleration
buttons

gps
gsm

I'm sorry for you.
- You could even try to change the wifi-channel to 1, 4 or 6 and disable wifi-security in the second attempt for test only.
- Try also to set a static ip in your phone (for your wlan).
- If you are bored you can reset the whole router to its factory defaults and leave all standard. Just enable wlan (and the isp connection) - but dont change the default ssid, wlan-security or channel etc.
Otherwise I have no more ideas.
With google you can find dozens of users crashing their routers with android or ios phones . Good luck dude!

Ive had this problem to since switching to 'randomblame's kernel based ROMS (jellytime CM, jellytime aokp and jellytime by PACMAN - Paranoid, CM and AOKP).
Apparently it is a kernel issue and the only thing you can do is some of the things above or here
I was here hoping there might be a fix... I tried static IP, changing the router channel, WIFI never sleep etc etc etc.
The only workaround I found so far was to turn off wifi when Im done, it only seems to break when the phone is inactive for 5 minutes +.

Exact same problem here. It took some time before I figured out that my phone was overwriting my gateway's MAC address, but I finally saw that message from another machine in my network:
Code:
arp info overwritten for 192.168.1.254 by 91:31:58:5d:e8:34
1.254 being my gateway's IP. I also tried giving my phone a static DHCP entry but it just didn't change anything. Any useful sysctl maybe ?
FWIW, it seems I "fixed" that issue by making my routers MAC address association permanent on my (manageable) switch. That obviously don't fix the real problem, but does not shut down the router's NIC. FYI, on a GNU/Linux machine, this is done with the arp command, i.e.:
Code:
# arp -s 192.168.1.254 00:ca:fe:ba:be:00
192.168.1.254 being your router's IP

Wi-Fi on custom ROMs

Last night I tried flashing cynogenMod 10.1.3 on my stock 4.1.2 Note 2. I followed their instructions, and everything went well but the Wi-Fi never connected to my router. It stayed saying connecting... then network saved. The password was correct. I restored my backed up ROM and on it the Wi-Fi was working. I flashed the cynogenMod Nightlies 10.2 and the same problem was there. I downloaded a stock ROM and flashed with Odion, and the Wi-Fi worked. I flashed Ressurection Remix ROM and on it as well the Wi-Fi didn't work. I tried a few non touchwiz ROMs and all of them the Wi-Fi didn't work, it only works on stock ROMs and TW based ROMs. Is there a way to know more about the cause of this issue? Did other experience such an issue as mine?
I would be greatly obliged if anyone can offer me help.
I have tried many custom roms of every type and build, never had any issue with wifi
perhaps you can try to setup static ip address on the connection instead of DHCP, see if that helps, or try installing something like wifi manager from the store, and use it to connect, see if it gives any more info ?
sorry if this doesn't help, can't think of anything atm

2x LG G3 with CM12 same mac address. Wifi issue. Original MAC??

I have 2x LG G3 d851
both have since i have installed CM12 the same MAC Address: 00:90:4C:C5:12:38 thats why i have Wifi issues on the same network.
i tried to change the mac address but after a reboot both devices get the same mac address again.
Is there a permanent way to change?
I dont know either whats the original address was?
Is it a known bug?
Thanks

Finally ... and a solution
Finally affirmation I am not alone.
I have two G3s in my household and noticed this since LP AOSP was available. Posted a few times and was told "user error." I have the exact same MAC address with every ROM.
Install Pry-Fi from the almighty chainfire and select "MAC spoofing while connected."
It took a couple reboots and toggling on/off for it to stick for me.

yeah but this is not permanent. keeps reverting back after each flash. i need to find my original mac address.
I also have this issue. Has anyone found a fix?
This may be inconvenient but possibly revert all the way back to stock make note of the addresses and then reflash i assume if you restore the original addresses should show up

I would assume this would get the original MAC back for us as well, as it is embedded into the hardware itself. The problem is that just having the original MAC doesn't fix the issue of CM12 assigning the "default" broadcom MAC address. (Sorry if that came out harshly).

I'm not sure if it'll be the same with you guys running G3s, but I'm having the same issue with my Optimus G Pro. I just flashed my phone back to 4.1.2 stock, and my MAC is still 00:90:4C:C5:12:38. The only time I've been able to change it was when I flashed a custom kernel for CM12 that had the random MAC address bug.
Next time I get a phone, I'm going to be sure to write down my original MAC address. Not that it matters...I haven't found any way to change the address which would survive a reboot.
I have been able to change my address by following the direction posted herehttp://forum.xda-developers.com/tmobile-lg-g3/orig-development/rom-cyanogenmod-12-0-t2945461/post57127283#post57127283
This does stick after a reboot but may not after a ROM flash/update. Hopefully this helps someone out as it should work for many if not all devices affected by this issue.

tldr; He was freeloading off his neighbor's wifi and the neighbor blocked him via his mac address. So he changed his mac address to get around it and the neighbor blocked that one too. Now he can't change it again and corrupted his network stack in the process.
