[Q] Phone will connect to open wifi network but not secure ones

Had my phone for a few months now and recently found that it can't connect to my secure network at home.
When I turn wifi on I get the dreaded connect/disconnect message while it constantly tries to connect to my network. If I leave it on then the battery will drain overnight while the phone tries to connect. I have an iphone which connects to the network no problem. As does my laptop etc
To try to fix this I deleted all my new apps, especially the push ones which give me news updates, etc but this has made no difference.
The weird thing is if I turn off my router's security then the phone will connect and works perfectly fine. I've tried using all the different security settings (even WPS) with new passwords etc and everything seems to setup fine on the phone except it just doesn't want to connect (or more accurately stays connected for a microsecond).
If I go back to an open network it connects immediately and stays connected.
I think this is the root cause of the wifi connection problems that many other people are getting. But I'm at a loss to try to understand why it won't pick up a secure network but works fine otherwise.
My phone is using 2.2.1 and has been rooted
Any thoughts?

Root the problem highly unlikely ..
Secure home network test .
Remove security from Router that is no password .
Remove that connection from phone .
Reboot phone let it pick up router and connect .
If it does then delete reset router password and add in phone .

Thanks for suggested fix. I'll give it a go and let you know if it worked.
Root was a bad choice of word..... I meant that while looking for a solution to my wifi problem I noticed many other people complaining that they can't connect to a wifi network for one reason or another and I was thinking that maybe broken security is a common cause of many wifi connection issues.. In my case there was nothing physical at all to suggest that security was an issue, especially since all my other devices work fine on the same network.

Hi, tried your suggestion but I still cant connect. The first time I rebooted the phone it knocked out my internet connection! I've setup a static IP address for my PC and the phone was insisting on trying to connect using the same address and creating a conflict. I fixed that so that's not the issue.
This is what I've tried..
I checked to make sure DHCP was enabled in the router, rebooted everything. No luck.
I tried adding an IP Address Reservation for the phone and assigning a dedicated static IP Address. No luck either
I tried connecting the device using WPS. It all went as it should - my router saw the device, added the mac address to the list of devices etc. The phone acknowledged the handshake. But again it still wont connect.
I checked the router log and it says "DHCP IP: (192.168.1.2)] to MAC address B4:07:F9:336:3D, Tuesday, May 24,2011 03:08:48" which I think is what it should say.
OK I've just fixed it!!! Or at least its connected.
All along I've been securing the network with WPA2-PSK. I just changed it to WEP and the phone connected immediately. I hadn't considered WEP because I read that its not that secure and I do all my banking etc through my PC.
I've tried all the other security options and only WEP works with the phone. I suspect its a compatibility problem between the phone and my router (a Netgear WNT834B v2) because both the phone and router work independently but not very well together. There's plenty of posts discussing the Galaxy S connecting to WPA networks so it can do it.
Now, after trying all the other security options. It won't connect again even on WEP. Bummer. It is acting slightly differently in that its trying to acquire an IP address instead of simply not connecting, although it doesn't seem to be able to find one.
I need to try this on a friends network and see if the router or the phone is to blame. I've no idea... but the phone's a bit too touchy for my liking

I had a similar issue, I had to reflash the ROM to get it to work. Backup all your contacts and stuff and then do a full factory resetting. See if that helps, if it doesnt, reflash the ROM. It should work.

Well I've spent the last few days looking into this issue and it's considerably more widespread than I first realised. The problem is that while many people have a wifi connection issue we all seem to have variations on a theme.
As I say in my case the phone will connect and stay connected to an open network but won't touch a secure one. I tried many suggested fixes and nothing's worked so I am now trying a factory reset.
A couple of questions: there appears to be two ways to do this, a factory data reset through the phone menu; and a hard reset using a combination of volume buttons, etc. The hard reset seems to be the deeper of the two.
When you say full factory setting which one did you mean? I am currently data resetting and therefore using the "authorised" Samsung reset
But how long does this process take? My phone has had a black screen and been vibrating every 10 seconds or so for the last hour. It's getting quite hot and there appears to be no end in sight. Has the phone hung or something? If it has how do I get out of this without bricking the phone? It's beginning to concern me because I'll have to do something real soon.
As an aside, in my search for a solution I found something that might help someone people (it didn't work for me). According to the bloke who posted it, the problem for everyone is that the wifi drivers have not been installed properly and if you enter *#*#526#*#* on your keypad it unlocks a service access that reinstalls the wifi driver. I tried it and the phone told me the software was installed successfully but no change.

Waited long enough so pulled the battery out and restarted the phone. I get the startup screen but after that the screen goes black and it vibrates again every ten secs and I can't get in.
Have to try the other reset.....
Things are going from bad to worse..

Have managed to start a full factory reset using the volume, power and home button but it's gone back into the black screen and vibrating every ten seconds.
I know Im going off topic here but Ive now reset the phone, wiped the cache, tried to apply the sd card update (aborted because it can't find the directory) and it always comes back to the black screen and vibrating every ten secs.
Am now trying to reflash the rom. Oden reports that the flash was successful but the phone wont reboot. I tried a couple of times - one with Re-Partion checked and the other unchecked but neither will reboot. What could be causing that? I somehow remember that my firmware was JPH but I could only get hold of JPK. Could that be the cause?

I seem to have solved all the issues at last. Thought it was going to be a bit over my head for a spell.
Once I discovered that the only way I was going to get into my phone was by flashing the rom the first problem I came across was I didn't know which firmware my phone was using previously, apart from the fact it was 2.2.1 and from Asia. I guessed wrongly and after "successfully" flashing the phone it wouldn't reboot. I then noticed that there were only three variations of the 2.2.1 firmware for my region. The second one I tried went a little further than the first but I got an error message about the SD card. The third one installed no problem.
So I instantly checked the wifi signal and the phone connected to the secured network. And stays connected - so far about an hour and a half.
It's amazing how the phone deteriorated the way it did. Hope it doesn't do it again.
Thanks for any help/suggestions

Wifi can connect, but cannot load page

Hi
When my phone is connected to either my wifi or my schools wifi, I receive an ip address, but I can't load web pages at all. Also, I can't sync my my google account. Thinking that it might be a DNS problem, I've tried to enter a static ip at home and using 4.2.2.2 and 8.8.8.8 as DNS' but nothing works either. I'm running the latest Cyanogen mod(7.1.2), as I thought wiping cache, wiping dalvik, factory resetting and reinstalling another rom would fix my problem, but it hasn't. I've also tried different radio settings in the androdiani settings. This happened a few weeks after flashing a nightly build of cyanogen, so I don't think that was the problem, but I'm not ruling it out as a possibility. Does anyone know what might be wrong? Google hasn't helped much either.
can't ping using the pingback test in *#*#4636#*#* either, and won't even load me 192.168.1.1(my home router).

I had similar problem, but for me the pages loaded, but I had to wait 5-6 minutes to load them(on most of the pages, but not on all pages). But if I was on mobile data the pages loaded quickly. Today I installed pre alpha CM 9 and with it, it was quick
The ROM which is not suggested for daily use is better

i'm having the same problem. i just restored it back to factory setting (at least i think i did) i can connect to the wifi but it cannot load anything.

my wifi has great signal,but if i root the phone the wifi signal is very weak what can i do?

It didnt work for me either so i restored to factory setting and wiping the cache
try it

i have the same problem.
maybe you should check Radio type.
is 802.11b？ You can try to exchange it for 802.11b\g\n
Very sorry for my english

[Q] Wifi issues on CM 10.1

Hello mates, this is my first time ever posting on the forums, so feel free to call me a newb
So here's my problem. I have been using [JZO54K]_android_4.1.2_v5_oficial_stock_rom on my samsung I9000 for a while and was quite satisfied with how it was working, but I always had a problem with the camera not focusing properly on the moment when a picture is taken. So I decided it's maybe time to try out CM 10.1 (i usually stay away from CMs because i had problems with it freezing or being slow or rebooting without me doing anything on it) hoping it would be a good and smooth experience. So I followed the thread and the instructions precisely (it's not my first time flashing a rom, by any stretch of the imagination). Everything went well, signed in with my google account, google play started restoring my account to the phone, installing the apps and so on and suddenly it stopped. The wifi icon turned from blue to gray, which i know means that it's not getting a connection. So i reset my router, connected to the secondary router in my home and still a gray icon. All my computers in the home work fine, so it's not an internet connection problem. My data plan is out of mb's, so that's noot gonna be an option for me.
So, then i tried opening the browser on the phone, keeps trying to connect, doesn't get anywhere. So i decided to go back to my original rom and guess what? I have the same exact problem. So i tried flashing and reflashing both for a few times, got tired of it. Tried factory reset from the phone's menu, tried clearing everything, all caches, dalvik cache, nothing worked. So i'm stuck with a phone with no internet connection over wifi.
If anyone else had this problem, please help. Obvious stuff will not help me, as I know my way around the block, not that new to this. But i have already tried all the stuff you would get on a google search (like checking if sync is on or opening youtube and all that other stuff)
Thanks in advance, in the mean time, i will be flashing the stock rom with odin and gradually upgrade back up to probably elite's rom.
I've also added a screenshot with my baseband and all that info

So i have just flashed 2.3.6 using ODIN, having the same problem. Will connect to wifi, all internet applications can't get a connection. (and yes, i did check the date and time, in case someone was wondering)

So i have managed to figure out and solve the problem. it wasn't actually an issue from the phone. i tethered another device and managed to get a connection with wifi. it was an actual issue with the way my routers are set up. i have a main router that broadcasts a certain DHCP which is connected to another router that just acts as a bridge. the main router broadcasts in an ip range of 192.168.0.100 to 192.168.0.199 and the secodary router (which i connect to using my phone) that acts as a bridge, usually, if it were not configured to act as a bridge, it would broadcast in ip addresses ranging from 192.168.1.1 to 192.168.1.199; both routers broadcast a different SSID, btw. so the main idea is that, any device that would get an internet connection in the house should have an ip address in the format of 192.168.0.xxx, and this is where the interesting part comes in.
after flashing and reflashing a few times, i started looking into the settings for the wifi on the phone and noticed that it was picking up an ip address of 192.168.1.66. the possible explanation would be that the main router might have stopped broadcasting the DHCP to the secondary one, and the secodary one decided to give it an ip address, hence the 192.168.1.66. but this still doesn't explain why even after reflashing the phone a few times, it still kept the same ip address, which is not suppose to happen, and even if i tried to connect directly to the main routers' SSID, it would still give an ip address of 192.168.1.66.
anyway, managed to get it working, finally decided to go back to elite's rom (after benchmarking on CM10.1, i noticed i get lower scores than what i would get on elite's). and i wasn't suppose to hard reset the phone, i was suppose to hard reset the routers, change the SSIDs on both which is easier and faster to do that anything on a phone.
I don't think that this would apply to anyone else, i guess it was just a freak accident in my home, but hey, if you ever get problems like the one i had, you might want to look into your routers as well

Wifi issue after MM update

Hi guys! Can you help me out! I installed several MM Roms, as i can not connect to certain wifi networks. I installed many of them to troubleshoot my phone. I have no idea why i can not connect, why it stucks. . It stucks at obtaining IP adress. Before i first install the marsmallow on 5.x.x series i was able to connect to any wifi network (obviously if i had the network key), but now i can not connect to my workplace wifi, also at my friend. At home it is all OK. All networks are 2.4ghz. Other then this i can not see 5ghz networks. i saw a solution for that, but most adb drivers are for x86 even if it says its for x64 systems (or either im too noob, buti can not install them on win10). But the main issue, which pisses me off, is the problem with 2.4Ghz networks. Does any of you have any solution for that. Furthermore, have any of you faced this problem before??? Thanks anyway! G.Regos

Yes, i tried that, thanks. The problem doesnt seem to be the encryption, as its passes through. The issue is with obtaining IP address. Maybe in MM they changed the way that DHCP(IP address obtaining) works. If i can not find a way to change that, i will have to revert back to Lollipop.

Oh! I see... that is a pitty! I'm thinking in advance to Android 6.0, but i hear several issues about it. So, meantime I´ll keep android 5! Hope you finda solution, best regards.

Hi Guys!
Accidently i found the solution for the issue. I share it with you, in case if anyone interested. If you tap 5 or 6 times on the build number, you'll be able to become developer. After this you go to the developer options, then scrolling down, you'll find an option to revert back to Lollipop tipe DHCP. If you tick that, you can connect to any wifi network. (in case if you have the network key) You'll no longer stuck at "obtaining IP address"... Hope that helps

VPN connected but IP is still transparent

Hi community,
Seeking help here. I have never had any issues with regards to VPN connection on my note 9. I have subscription with CyberGhost VPN however I also have free versions of Thunder VPN and X-VPN.
The issue which occurred today that I cannot fix. I am able to connect using both the paid/free VPNs mentioned above, however once connected, my real IP is still transparent.
When I open the 'key lock' android system VPN management popup, I can see that no data is sent or received even though I have surfed web, watched videos etc. I used ipleak.net to confirm the when connected to VPN my IP transparent.
When I restart the device and connect vpn, it works normally i.e. ip not is transparent. But after some time it automatically becomes transparent again. Power saving is never on. I have to restart device again for VPN to work normally again, albeit a short time.
Anyone encountered similar issue and/or have any solution?

I am having the same issue as well, first everything worked fine and suddenly vpn is not working anymore although it says it is connected. I am using Cyberghost as well but tried other software with the same effect (connects normally but no data goes through the vpn connection)
Haven't found a solution up till now, it is very annoying.
Where did you buy your note 9?

Mine is Australian version from Optus. No solution so far. I contacted samsung and they told me to do factory reset.. haven't tried that yet. So annoying!

Hmm ok yes i saw that too as a probable solution when people with older Samsung devices had a problem like this but factory reset i only want to do as a last resort because it's going to be a haggle to set everything right again. If i do it and it works i will reply again.
My one was bought in Thailand by the way and model number is SM-N960F/DS

Same model as yours except not DS. It seems to be a software issue. Don't know what has triggered this. It was working just fine.

It must have been triggered by the latest software update because my nephew in the Netherlands has the same issue when he tried to use the vpn just now. It worked after rebooting the phone and then his connection dropped after 10 minutes and now his vpn connection isn't working anymore.
So three Note 9 phones all bought in a different country and region have the same issue, weird that this problem hasn't come up on forums more unless the cyberghost app broke our vpn capabilities..

Oh ok that is interesting. I tried other free vpns also with same result. But I was using cyberghost before this problem...
I really don't want to do factory reset.

Same issue in Canada
I am in Canada and I'm having the same issue. What I have found, is it if I download a DNS changer, and I change the DNS, once in awhile it starts working again. But this is completely unreliable.
This seems to have been an issue for a while and for a business marketed phone, it's quite perplexing that Samsung/Google have not dealt with this issue yet.

I got a temporary solution from cyberghost. It's requires setting up L2TP vpn connection. It's not as fast but it does the trick for now. I noticed from my searches this has been an issue since Samsung S8...hopeless!

Is this a Samsung problem or an Android problem? Samsung is telling me to send my Note 9 in for repair bit I am not convinced there is anything they can do. I have tried a factory reset but it was of no help.

I guess deleting all VPN profiles from device but very one will do a thing

Did the latest samsung update but still doesn't work. Any solutions?

The only solution that worked for me is to set up vpn manually.
Add a new device at Cyberghost account management and manually enter the pre-shared key, username and password given and choose ipsec protocol and on your device choose L2TP/IPSEC PSK.
Then you have to connect to the VPN there instead of the Cyberghost App and you will have full vpn functionality although slower than the app which is using OpenVPN or Ikev2 protocol but it's better then nothing.

I use OpenVPN for Android and under Advanced you need to set 'Use VPN for All apps except' and set route all traffic over VPN.
This did change somewhere in Oreo, it didn't used to be like this.

betternet vpn works a treat. no issues with transparency 48hrs after reboot.

PIA works without issues.
