thats sucks its even happening on 5Ghz band too :crying:

i hope 4.2 will fix the crappy issue :mad:

BTW the same problem on GS2 with 4.1.2 too

Samsung seems messed with Wifi driver :/
[Galaxy Note II Q&A, Help & Troubleshooting] Televinken:
Yup. Since they messed up the 4.1.2 update with all these wifi issues IN JANUARY,

I have lost all confidence in Sammy over the months. With the 4.1.1 wifi worked ok.

If the issues are still there in 4.2.2, I'll start look for a more reliable phone brand...

I fully agree. I got a HTC One for the job so I get fed up with the lag and the Wifi mess of Note 2:(
[Galaxy Note II Q&A, Help & Troubleshooting] Atsco:
This bug is in Samsung stock kernel, so if you flash a ROM, that uses stock kernel, problem is still there. But good thing in custom ROMS is that you can change kernels. I use Omega ROM, that's uses stock kernel, but I flashed older kernel, and now WiFi working fine. I have to use stock kernels, because with custom kernels Allshare Cast Dongle is not working. And I use that Dongle quite often. That problem is in every stock kernel after XXDLJ2.
[Galaxy Note II Q&A, Help & Troubleshooting] yahyoh:
u mean AOSP roms? i think they are using non stock wifi driver so it should work without problems

the problem seems only with Stock Samsung kernel for 4.1.2 ( and the kernels that using stock 4.1.2 Wifi driver ) on 4.1.1 no problem whatsoever

Low WiFi TX Power

Yet another GN2 (SPH-L900) bitten by the 4.1.2 WiFi issue. WiFi was working fine up until I installed the MC2 firmware update. I've tried factory resets, dropping down to older firmware, dropping down to older kernels, copying the wifi folder from older firmwares, the 0011 power-save-off trick, swapping routers, and nothing has worked for me (while on 2.4Ghz 802.11b, g, or n).

One thing I haven't seen explicitly mentioned in this thread is a symptom which may help us understand what is potentially at the root of this problem: unusually low TX power. I had noticed for a while that, while I had good signal coming from my AP when this issue is occurring (usually better than -60dBm), the rate of the WiFi connection was usually well under what would be expected (1-5mbps).

If my incoming signal from the AP is good, this implied that the transmit signal was weak. Sure enough, I logged into my DD-WRT-based router and saw this:

Of all the WiFi clients in my house, my GN2 was by far on the low end of the signal power. It would appear that at the root of this issue is something that is causing the WiFi chipset to drop down the TX power well below what it should. The result is that the phone will try to connect to the AP because it sees a strong signal, but return communication is very unreliable, resulting in flaky DHCP behavior, slow-to-no internet, and ever-degrading wifi rates, until finally the phone gives up and drops the connection.

Also, It's been noticed a number of times in this thread that some 802.11n devices will work. I've noticed the same, however this is only the case when the phone connects using the 5Ghz band. It would appear that this bug/defect usually affects only one band or the other. In my case (and perhaps most others), the 5Ghz band works fine.

I wish I had a solution for you. But I figured that noting this publicly might allow someone else to get to the bottom of this until (or if) Samsung ever fixes this issue.

Side note: I used to own a good number of Samsung devices, all of which died within a year of purchase. I vowed never to buy another Samsung product again. I've warned others of the poor quality of Samsung products, and seen similar results when the warning was ignored. I was lured into purchasing the GN2 with it's ample size, NFC, and pressure-sensitive stylus. I thought: "Maybe this time I won't get burned". Now I think I would have been better off "settling" for a One X that actually worked. Prove me wrong Samsung, please!

Update: Also tried out MacksRom AllStar 5.0 with no improvement.

Update 2 (6/28): Add to the list of attempted "solutions": WiFix app, changing country code, flash back to stock w/ flash count reset.

Hi,

Is anybody tryed these solutions?

http://androidforums.com/avail-all-...i-fix-obtaining-ip-address-loop-found-me.html

http://xdaforums.com/showthread.php?p=10091160

I have the same problem with my N7100 such "IP addres abtaing". But I didn`t perform these actions bellow with my phone.

SOLUTIONS:

1. system/etc/dhcpcd/dhcpcd-run-hooks needs to have permissions fixed to "execute" by "user" "group" and "others" by using your favorite file explorer

2. rm /data/misc/dhcp/dhcp_list

It seems to come from the fact that the phone requests its previous IP address to the access point, without any discover message, whereas the lease has expired from the AP point of view...

The previous leases are stored in /data/misc/dhcp/dhcpcd-eth0.lease and /data/misc/dhcp/dhcp_list. You just have to remove the second file (dhcp_list) to force the phone to start a new dhcp negotiation.

If it`s really works, please, share your experience here.

I`m now under stock MDE6 4.1.2 and tryed to fix "IP addres abtaining" - flashing customs 4.2.2 ROMs, reinstall stock 4.1.2 & 4.1.1 ROM, *#0011#, moved wifi files from 4.1.1 - it didn`t work for me.
[Galaxy Note II Q&A, Help & Troubleshooting] Televinken:
It has nothing to do with neither root, nor OTA updates. Wifi worked fine on 4.1.1

How to fix "IP address obtaining"

I want to share my experience how I fixed this issue with Note 2.

Let me start from the begining.

I bought Note 2 with stock 4.1.1 ROM.

There are two wifi points at my home (D-Link 615 and Time Capsule) it was connected great to them, and every time it was different dynamic IP.

Few days later I did upgrade to 4.1.2, note 2 was connected to wifi good as well. Also wifi worked in aiports.

When I came for a job to my remote camp for one month, I did connection to wifi (it is only one wifi point here) so note 2 was connected.

Day later I came to my room and I can`t connect to wifi (it stuck "IP address obtaining") but my macbook air, friend`s laptop and iphone were avaibility to connect.

i guessed that the problem is with MAC address, (wifi point remembered my MAC address and IP (DHCP) for my Note 2), because other devices had the same dinamic IP after disconnection and connection to/from wifi point.

Sometimes, when I switched off and on wifi on my note 2, I got the connection with the same IP address.

SO,

I install Wifi static from google play. You can collect many of wifi points in this application, it will connect automaticaly to different wifi routers without IP address conflict.

When I get a chance to connect to wifi I open this application and it`s remembering my network settings.

Now it works great, I can turn wifi on and off and it`s connecting with no problem.

OTHER SOLUTIONS,

If you an administrator of your network (wifi) , you can prevent to remembering MAC address by the router, It needed that Note 2 asking every time new dynamic IP address not reserved IP, because it`s trying to receive a new one IP and stuck in this case in "IP address obtaining" .

Also I put some pictures for your better understanding (sorry some of them in Russian), but it`s just for your common imagination.

Sorry for my English, it`s not my native language)))
[Galaxy Note II Q&A, Help & Troubleshooting] barbon:
Did you try to put off Wifi Power Safe Mode? You can acces the menu of it by entering #*0011# You can dial this just as you are dialing a number. Now you are in Service Mode. Press the menu (hardware) key and push Wifi in this menu. Here you can put Wifi Power Safe Mode on and off. If i dont put it off myself the wifi gets very very slow till it dies. All my other devices work great on my router so it must be a Note 2 issue.

Hope this helps for you to.

Wi-fi not even turning 'ON"

Ok so recently after the update my WI FI is not even turning on, is this a software issue?? :confused:
[Galaxy Note II Q&A, Help & Troubleshooting] ursamajor_nl:
This issue is complicated.

For so far there are people who could not connect to wifi at all and people with wifi performance drop after deep sleep.

I also have the problem that when wifi is just turned on, the speed is against maximum of my internet connection (25MB). But after a while the speed drops to 10 MB and even later below 1 MB. When I restart wifi, the speed is good again.

That's with my home router tp-link tl-wr1043nd.

At work there seems to be no problem with wifi. I don't know what hardware they use here, but I can imagine it is somewhat more professional because of the supported number of people that are dependent on it.

Perhaps there is some workaround that works on many routers... But still it is a problem that Samsung should resolve...

What didn't work:

-disable wifi energy saving

-static ipadress

-tell the router to remember my mac address and assign a reserved ip address to it.

Long-time lurker first-time poster here - Galaxy Note 2 (obviously) on Verizon running 4.2.2, rooted with ParanoidAndroid 3.1.5. THANK YOU SO MUCH for posting this, I was having the same problems as everyone else (endless "obtaining IP address" loops, or when I connected to wifi no data would transfer) and nothing was working, was so afraid I'd have to reset to factory settings... I tried your top suggestion of changing the permisions for "dhcpcd-run-hooks" - when I checked the permissions there, "User" had execute permissions but "Other" did not - so I changed it using the instructions in the first link, restarted and voila, instant wifi with full data.

[Galaxy Note II Q&A, Help & Troubleshooting] muchtall:
I personally think it depends upon the problem you are having.

If the problem you have is that the signal level looks good on the phone, but when you connect the speed of the connection progressively drops OR you can't make a connection reliably, that's likely an issue with the WiFi radio on the motherboard. What is unknown is if this is a problem created by a firmware update or not. My personal experience was that my phone (SPH-L900) received a 4.1.2 update (MC2) about the same time I started having problems. So there may be hope that this is a firmware problem. There's also the possibility that (if it was the firmware update that caused the issue) the firmware update somehow overloaded and fried the transmitter/amp in the chipset, and therefore a firmware update backing out the change won't help. This appears to be my case. No amount of messing with older radios or WiFi folder swaps had any effect. I had to send mine in for warranty "repair", which will probably mean motherboard replacement.

If the problem you are having is that your signal looks good, and WiFi connects but hangs

every time

on trying to get an IP address, even when you stand right next to the AP, it's possible that you have a software problem. Lot's of people have had anecdotal success with messing with permissions and static IPs. You could also try a custom ROM and see if that helps in this case.
