That sounds boring!

Anyway, it is an issue with SSID being hidden or not at least for my Note2 and Netgear routers it seems.

I tested it out at home and at work and both use different Netgear routers with same SSID issues.

My note 2 drops in and out whilst in playstore but noticed that the download speeds were low (hi traffic from 3 laptops etc) often wobbling around anything as low as 400k to 1.4m.:( My streak did better averaging 3m.

After following this thread tried the hidden menu, no real difference.

Checked/read up on the router settings. I have a Dlink device "DIR615" that has WPS button on the side, the note has a WPS menu (Wifi + menu button)

Advanced . WPS push button. WPS pin entry.

Whilst beside your router select on the note WPS push button. press the WPS button on the router so it lights (it's like blue tooth pairing).

On completion I had a new router identified "Dlink7d76" connect to that and I now have 4.181 / 4.969m download speed (2 tests),:D Now that's better! the "7d76" I would expect to be a variable.

Maybe our devices are fussy and a generic connection is not a close enough sync.

Worth a go as we seem to be chasing our tails more than a little? Hopefully it will remain stable and not be "lost" on reboots. :fingers-crossed:

Seemingly it is behaving.

3.9, 4.2, 4.9m this morning.

Although I had not used this method previously setting up the router/network, obviously I had no foreknowledge of what to expect and as for the password reset into 64 bit, who is going to try to remember that! That caused a panic when our laptops wouldn't connect.

We learn something daily and life is not going to allow us to say "I know everything".

Hi,

Regarding the Wi-Fi issue, my phone can't detect my Wi-Fi network, I clicked the scan button but it couldn't detect it, I tried adding it manually but it gave me a message that the network is not in range!!

All the devices in my home including smart phones and laptops were connected to Wi-Fi except for the galaxy note2 N7100,

Why it can't detect the network?

I'm wondering if it is a hardware problem? should I return the device? :(

P.S. I forgot to say that I don't have a wireless router, I used my laptop to create an ad hoc connection and it worked fine with the other devices.

[Galaxy Note II Q&A, Help & Troubleshooting] Lily Sammet:
Well, I couldn't find how to enable the ssd for an ad hoc network but your answer gave me a hint.

While googling for ssd, I found that an Android Os can't connect to ad hoc networks!!!! ( I'm using Android for the fisrt time)

so I used a virtual wi-fi router for my ad hoc network and followed the steps that were listed in a site (sorry, I'm not allowed to post links)

and bingo, it worked :))

[Galaxy Note II Q&A, Help & Troubleshooting] farfromovin:
My Note 2 (SGH-T889) has always had slow wifi. It might work good for a couple hours here and there but consistently the speed will drop to probably sub 1mbps. All the other devices on the network are solid, network interference is very minimal, security is WPA2. I have 3 separate access points in the house all on separate channels. Only 1 of the access points has a little competition with a neighbor router but it's a good 20db stronger. I've restarted everything, factory imaged as well as ran every custom rom available. Wifi is just intermittent. With or without a phone case, with or without holding it, can't seem to get to the bottom. It's so bad, I'll often disconnect from home wifi if I'm downloading a ROM on my phone just to use HSPA instead!!! This sucks and I'm open to suggestions.

GT-N7100 international. WiFi worked excellent on stock and custom 4.1.1 roms.

After flashing 4.1.2 based Omega I was able to connect to 802.11n networks only, unless I did Stegar2108's trick described here http://xdaforums.com/showpost.php?p=34501055&postcount=57 (but I had to do it everytime after reboot if I wanted to connect to any other network but 802.11n).

Just tried latest 4.2.1 based Hyperdroid and WiFi again works excellent.

Certainly looks like problem with some (otherwise we would have about 100+ pages in this thread instead of 11) phones and 4.1.2 roms.

So, basically, since for the time being I do not want to switch from 4.1.2 based rom to any other If I visit someone and want to use their WiFi I have to use *#197328640# menu trick.

Seems like workaround but I hope someone will come up with more permanent solution finally.

Very poor wifi range

I have the exact same problem.

Could it be the hardware antenna that got loose, or something to do with an update. It worked fine the first month.

Now even tried several custom rom's to try if the original rom was giving problems. And still have a really bad range.

Standing +/- 6 meters from any AP only 2 bars. If i want good connection I need to stand right next to it.

I could be in the wrong thread and if so I am sorry. I was experiencing these same issues with my AT&T Note II. If you have ever opened AT&T Smart WiFi on your device and then used the android settings to change WiFi settings it causes problems. The AT&T app even warns you of that on the startup. I went back to the app and my problems went away... Just my 2 cents.

this worked for me:

start connecting to the network, let it stuck in "obtaining ip address"

it should restart wifi connection automatically.

Hello folks.

I too had the same issue where any 4.1.1 ROM would connect fine and any 4.1.2 ROM would fail to grab an IP address, or tell me poor signal, or connect but refuse to surf, or connect, surf then kick off.

Tried all the tricks listed: power save mode didnt do anything, and anyway, it resets itself on boot so not ideal. Actually got a new router from my ISP duting all this (unrelated cos was free upgrade anyway!), tried changing every channel blah blah. Thought I would just have to skip 4.1.2.....

I NOW HAVE IT SOLVED AND **AM** RUNNING 4.1.2 (one of the many ROMs I had tried and had failed before)....

Flashed the 4.1.2 ROM like usual. Is a custom ROM so was already rooted (happens to be ARHD8.0 but pretty sure this trick would work on any other ROM). I then took the entire "wifi" folder from the working 4.1.1 ROM I had installed before (err.. yeah...forgot to mention that I copied it off before I flashed! LOL!). I turned OFF wifi, and used ES File Explorer to DELETE my 4.1.2 wifi folder and paste in the 4.1.1 version. I then changed permissions of the folder to match the old one (in ES File Explorer the 'shape of the tick marks' should be "up-across-down" if that makes sense). I then went into the wifi folder and made EACH FILE have same permissions cos they didnt seem to follow the parent.

Rebooted, turned on wifi and boom! Works as great as it did in 4.1.1. Found my WLAN and got an IP instantly and stays connected and surfs at full speed.

Apparently there is a known bug in 4.1.2 Android that is causing this, so we just use the drivers/files from 4.1.1 and it works great!

Hit thanks if this helps, which I certainly hope it does.

(I found the solution elsewhere so not pretending I discovered this; just passing on in good faith)
[Galaxy Note II Q&A, Help & Troubleshooting] sprkrt:
Where is that wifi folder? There are 3 folders named "wifi"

Also can you give us the original link?
[Galaxy Note II Q&A, Help & Troubleshooting] asifanwaruk:
Use a root explorer and go 'up' until you are in the "/" folder and you will see lots of folders, one of which is called "etc". Go in THERE and you will find the "wifi" folder. There was no original link where I got the 4.1.1 files from; I just copied them off my working 4.1.1 ROM before I wiped it away. Any working wifi ROM should be good, but I would suggest a 4.1.1 version of the 4.1.2 you plan to use (eg I used the folder from ARHD4.1 which is 4.1.1 cos I was planning on flashing ARHD8.0 which is the 4.1.2 version of it).

Hope this makes sense.

EDIT: Going to try to attach a screengrab from ES File Explorer so you can see the folder I deleted and replaced. Hope this works.

update 4.1.1 to 4.1.2 - no WIFI -- FIXED

I purchased my Galaxy Note II (GT-N7100 without LTE) in Hong Kong on November 18, 2012. Upon returning to the United States , I used the phone without any problems, until February 2, 2013, when I received notification on my phone from Samsung that a software update was available for my phone. I clicked the icon to select installation of the software update, which resulted in my phone being updated (over-the-air) from OS 4.1.1 to OS 4.1.2 After installation of the update, I was unable to receive WIFI from my Netgear WNDR3700 Wireless Router, except on rare occasions. When attempting to connect to my WIFI, the connection is unable to proceed beyond "obtaining IP Address". Prior to installation of the update, the phone connected to WIFI without problems.

I emailed Samsung (HK) about the WIFI problem, and within a few hours I received the following response:

>>This is an E-mail from Customer Service Department of Samsung Electronics H.K. Co. Ltd. Thanks for enquiry. According to the symptom, >>please kindly back up necessary information and perform the below setting.

>>Setting -> Back up & Reset -> Factory Data Reset

>>Thank you for your supporting to Samsung product. Should you have further enquiry, please free feel to contact us at (852)3698-4698 or visit >>http://www.samsung.com/hk and click "Contact us" button to send E-mail to us, we are always at your services.

>>Yours Sincerely

>>Customer Service Department

>>Samsung Electronics H.K. Co. Ltd.

I performed the Factory Data Reset in accordance with Samsung Instructions, and I was able to connect to WIFI from my wireless router. However, when I subsequently turned off WIFI on the phone and then turned it back on, I could no longer connect to WIFI from my wireless router. The sequence of events is as follows: 1) I select my WIFI connection from the list on my phone -- the display indicates signal strength "very strong" and Security WPA2 PSK. 2) I enter my password and click "connect". 3) The phone displays "obtaining IP address" 4)After about 1 minute, the phone displays ""Network Disabled Poor Connection"

Other Observations: 1) My other smartphone (original Galaxy Note) continues to receive WIFI from my Netgear WNDR3700 Wireless Router without problems. 2) I am able to connect to unsecured WIFI on the GNote II from one of my neighbors

UPDATE 1: I switched from 2.4ghz to 5ghz band on my wireless router and phone and now my wifi works at home. Still can't use WIFI (only 2.4ghz available) at locations away-from-home.
