School Wi-Fi access stops working after 15 seconds - Samsung Galaxy Note 8 Questions and Answers

I have a problem where I can connect to my school Wi-Fi, it works for about 15 seconds, then the '!' Appears over the Wi-Fi symbol and it stops working. My school account login works on my previous Oneplus 2 phone as well as my laptop. I have never had problems on this network before using this phone. My guess is that it is some sort of authentication process, as it works for a little bit, before the network seems to recognize my phone as malicious and bans it as shown below. The phone is not rooted, and the network account works on all my other devices. I tried resetting the network settings, and I'm nearly sure it's a network side issue that could be solved, but is there any other way to possibly get around this or spoof my dns?

Do you have any P2P / torrent / etc apps? My work picks up any activity like that as 'malicious' and auto-blocks the device completely.

internet access issues

so for apparently no reason today my internet stopped connecting. When I go to connect it says -
Dialed: wap.cingular
it says underneath it there is no modem at the above number.
ummm.... I didn't change anything in my setting but for some reason it won't connect to the 3G network. Any ideas here or do we know whats going on?

OK check this
START/SETTING/CONNECTIONS/MANAGE EXISTING CONNECTIONS/PROXY SETTINGS
and make sure that there is not a Check in the box next to :
THIS NETWORK USES A PROXY SERVER TO CONNECT TO THE INTERNET
This should do the trick I hope.
This always happens to me.
didnt work
no dice. its still giving me the same bounce back message that theres no modem at the above number. do i need to put a proxy server in the proxy server field? by the way this is a Tilt.
What program is trying to access the internet when this happens?
The same problem is occuring for me. I tried what Vol22002 suggested, but still can't connect. I was trying to access Internet Explorer.

First thing this morning I tried to access the Internet with Opera and got the "Dialed: wap.cingular Cannot connect for unknown reason. ..." error. No recent changes to phone configs or software, worked fine after midnight last night. Power cycled and checked the usual stuff, still no data connection regardless of program.

After not working from 0700 to 1050, I 'suddenly' have a working data connection. Go figure.
You'll probably find that this happens when your network is down. This happens very occasionally here and then I call my service provider to confirm this.

I would say that is the most common reason for the problem the OP is having.
the netowrk isn't down....
My dad's phone (not a tilt) is connecting to the 3G network completely fine. I can't access the internet through any program...internet explorer, opera, google maps, livesearch, the weather tab on my today screen...nothing. I'm at a loss right now.

So Disable the Proxy.
still nothing...with or without the proxy on.
I've been having problems with my data connection and phone service dropping out for the last 2 weeks even though I have changed nothing on the phone. I see an x by data connection and exclamation point by phone. I'm using Dutty's 6.1 official release and radio 1.58.26.20. Usually I can get back service by turning on and off airport mode, and the problem is very sporadic. Usually only when I really need the phone to work! Sometimes just switching between GSM and Auto mode for 3G will provide a temporary fix. I just tried disabling the HSDPA, and we'll see if that helps in a more permanent way. I wonder if AT&T is kicking people off of its network that are using HSDPA before it is supposed to be available. I called AT&T about the issue (w/o mentioning the cooked ROMs or HSDPA and they say I should return the phone for warranty but I don't want the hassle of restoring the old ROM. Any ideas?
is everyone posting here with issues from ATL? I am and have had the same, figured its just a radio issue and have been too lazy to change radios...for those that aren't lazy, i'd try that...
nope, I'm in Oregon. I'm of the opinion that AT&T has changed something about how they run their phone and data networks (perhaps in preparation for the 2nd gen iphone and HSDPA) that is randomly kicking people off their network.

There goes the iPhone messing with Smartphones again. First changes what a Smartphone should be. NOW messing with the network. Hulk Mad!
Nope its not just AT&T im experiencing the same problem over in the UK. Now my proxy is disabled and I know I have all the correct settings but still the error message "unable to connect to the receiving modem." It seems to have no pattern for this happening con we get correlation on what ROM's & radios everyone are using to see if its that

[Q] Am I the only one experiencing these 2 issues in regards to WiFi

Having had my LG 2x for a bout a week now I have come to find that it suffers from 2 issues I find annoying, and bordering to simply slack in making from the side of LG. Issues such as those should simply NOT excist on a phone such as this one :/
1:
I use my WiFi at home but sometimes I see that I am NOT connected to it and go into WiFi settings only to find that it says my network is "Disabled". How has it become disables, and why is the questions I would like to ask. I would like to know what causes the phone to think that.
Again my former phone was an HTC Desire and it used and connected to my WIFi network without any problems or issues leading me to suspet that this error is simply caused by LG either by fault in the hardware or a bad software that they released their phone with.....
2:
Sometimes if WiFi is actually enabled I will not be allowed to toggle on regular mobile data. The phone replies with the message "WiFi Connection open, cant open Mobile data" or something of that sort. I have gotten that message a few times over the last week and it comes regardless of whether or not my phone is actually connected to a WiFi Network or not.
Which basiclaly means that I cant use mobile data without first disabling my WiFi, reenabling mobile data and then reenable WiFi and then it works again.... for the time being.
Sometimes the phone also just disables mobile data on its own meaning I cant get any data connection unless I do the procedure above again. Its simply annoying and something that just shouldnt happen on a phone of this caliber . And with that comment I mean both the issues, because its simply not supposed to hapen for a phone in this price range or of this caliber.
All in all it seems more like LG cutting corners to be the first ones to release a Tegra2 phone. Cutting corners meaning that we have to content with a phone full of errors and bugs
I am having the same Wifi issue, it disconnects for no reason.
Hopefully this will get fixed soon in a 2.3 update. This minor wifi bug does not irritate me that much, the phone otherwise is a beast.

I had the same problem. It was caused by the wireless security/encryption method used in my router. I changed it from WPA2 Personal to WPA2 Personal Mixed, and now the router no longer disconnects my phone from the Wi-Fi. So try that.
You could disable the router wireless security entirely just to test ...

Well, I never leave the 3G connection on if I dont use it, so I can't answer you there. But Wi-Fi have greater priority than 3G. This means that enabling the 3G connection when having the Wi-Fi on and connected does not do anything. The 3G connection will only connect when the Wi-Fi is disabled.
It was the same on my former HTC Desire.

Sorry if I am a bit blunt. But that security setting has worked up till the point where I got my LG 2x, it works between all my laptops, on my SE G900, and worked flawlessly when I had my Desire, ie then its LG's issue and they just need to fix it.
IMO I can live with it getting tits up once in a while, AS LONG as it is fixed when LG releases Gingerbread. LG should however be asked why the phone "disables" the connection.
But I just checked my AP and its present setting is WPA2/WPA Mixed Mode. And the other "options" I have is: WPA2 Personal, WPA Personal, WPA2/WPA Enterprise Mixed Mode, WPA2 Enterprise, WPA Enterprise, WEP, RADIUS and Disabled.

I think you misunderstood me there . WiFi is turned on, but NOT connected, ie it should default to 3G data. But if I click my icon to turn on 3G data I just get told that it can't because WiFi is active, which it isn't since its not connected to any Access Point.
When I leaves my apartment I leave my Wifi on, and the second I leave the reception area of my AP the phone automatically switch to 3G data and back to WiFi again when I return. And thus I tend to keep both "on" to allow that seamless transition. In effect I could technically just disable my WiFi and stay on 3G considering I have a 25 Gig limit, but using my WiFi at home is just so much faster

I have the "disabled" status occasionally on my phone. It's triggered by 3 unsuccessful login attempts to the AP. This can happen if you're on the very edge of WiFi range but not sure that applies in your situation.

Well it might be that error that I am falling for then, but its just strange that the LG stalls, while my HTC Desire didn't seem to care and just grabbed the connection.
I wonder if there is some way to change it to try like 100 times or just completely ignore the limit and keep trying till it gets through.
I just had the "Disabled" issue again while sitting at home and being what 2 feet from the APN, so its certainly NOT a range issue :/
Hopefully this gets fixed with Gingerbread or I might go looking for another phone.
i have this problem with my folio and my 2x....
disabling wifi and enabling wifi helps.
for my folio i can say its a screen sleep issue(something messing with wifi as well,no solution afaik).
so if im downloading stuff and the screen goes to sleep my download stopps.
sometimes it resumes after wakeup, and wifi works fine, sometimes not.
for my folio the solution was to use the dockingstation, couse then it changes to a clock, and the screen doesnt time out.
today at work i was downloading stuff over my 2x, and expierienced the same strange behavior.
dont really know if its related(both tegra2 devices so it could be), but the occurance is too similar.

Well disabling security will do me no good at all considering I dont want to leave my wireless network sitting open like leaving my house unlocked.
So no thats not really an option... sorry :/
Of course not, but have to tried? My earlier, and now, is that your problem may be caused by the security on your router. It was a problem I experienced.
I have not tried yet. Because if i turn off the security and my phone then stays connected then its not a solution >_<. Its still an issue that the phone is causing.
BUT that said I would need to leave the security off my wireless for at least a week in order to really get any reliable data on whether or not its the security setting in the router that causes the issue (But I think rather not when all other phones has no problem with it). And sorry to say this, but im not leaving my internet open for a week to determine whether or not disabling my security makes my phone able to stay connected.
My HTC Desire could get connected and never disabled WiFi on it self. And the LG 2x does it. Ergo it must be an issue on the phone when it is the only phone in and around me that causes that issue.
have you tried changing the pw to a shorter one? in the shop where i work, some devices have problems with long passwords. some just connect to the router with the 10 char pw. connecting to the other router(20char pw) is sometimes a problem. the two routers are the same modell.
EDIT just tried it with the optimus, both router work, so this wont be an solution. sorry

[Q] Wi-Fi connects but doesn't work?

So I have somewhat of a strange issue with my wi-fi on my captivate. At home, my WiFi works great, no issuses. But when I go to my college, I can scan and connect to the WiFi spots but it still acts like I'm not connected. No data apps work at all, everything 'Fails to connect'
Using Wifi Analyzer, I see that its a strong connection. Even tried connecting to different channels, walking around trying different hot spots.. still no difference.
Why would my phone do that? Is there different kinds of WiFi networks phones cant connect to? But like i said, it see's and connects to the hot-spots there, just acts likes theres no data..

I had this issue last night when I was at a Hilton. IT saw the connection and connected but no data transfer. Found that when I connected to my laptop it redirected me to a page to enter the pswrd. So when I connected my phone again I loaded up the page from the laptop and entered the code. then it worked. Not sure if it helps
When you connect to the open wifi network simply open your browser and you should find instructions for that establishments network.

I started having a similar issue. I connect and get no data connection anytime I'm on wifi. It's happening on stock 2.1 and all 2.2 roms. After about two weeks of this, I called and am getting a warranty repair. I've had this phone since early august and never had any wifi problems.

When you connect to the connection that is not giving data, open your browser. Some places instead of useing a pin code use a webpage where you input the code.

[Q] Wifi problems with multiple router networks

I seem to be having pretty severe wifi issues on networks that are composed of a large number of routers (i.e. campus/business networks) where going between routers will result in the phone believing it is connected, but not being able to send/receive data. This is evidenced both by the lack of notifications/apps working, as well as the wifi icon in the quick toggle panel being orange (which indicates no data being sent/recieved, I believe) despite having full signal. This means that without any external indication that anything is wrong, my phone essentially does not work anymore until I turn the wifi off and back on. Previous phones (galaxy nexus, droid) as well as computers did not have this issue on the same network.
Has anyone else noticed this problem, and if so, found any way to get around it other than remembering to reset the wifi power every time you move between areas?
It sounds like there are multiple WAPs all using the same SSID, and Android is not requesting a new IP address when it disconnects from one WAP and connects to another. You could probably work around the issue using Tasker, and have it toggle Wifi off and on again any time Wifi is disconnected. I you go that route I would recommend using the trial version available from the developer's site, or one of the many similar apps that are available in the Play Store for free.
There may be something more to this though. Hopefully someone else has another idea.

I'm having the same issues both out in public and at my home. This issue didn't seem to exist prior to 4.4 update. Now I'm constantly having to toggle my WiFi on and off or toggle airplane mode and also hitting the symbol down at the bottom left on my phone and on my router at the same time. If someone has any information to correct this would be great. Like I said I never had this problem prior to 4.4.

Thanks for the suggestion! One question though: does the wifi actually "disconnect" when there is a handover between two routers of the same network? Is a handover while constantly connected something tasker could detect?

As far as I know, Android doesn't "roam" seamlessly from one AP to another even when the SSIDs are the same. I'm pretty sure Tasker would see this as Wifi being disconnected (albeit briefly). You could then tell Tasker to turn off Wifi for 5 seconds and then turn it back on again.

I finally got around to making a tasker script to do this, and tried it out for a few days, but unfortunately it does not seem to detect the changing between the different routers on my institute network as having the wifi disconnected, and thus doesn't solve the issue. It was a good idea to try though!
I've cross-posted the issue at the link below in hope motorola will see this, but if anyone knows a better way to report this, please let me know.

Cellular Connected but No Internet (17.0240.2007.27)

Version : WW-17.0240.2007.27, non-root
Hey everyone, I have been using the latest firmware of the ROG Phone 2 as they release from the Asus website, the latest firmware has been fine although suddenly the cellular data has stopped working, (besides some apps I.e Spotify recognises a data connection and can stream any cached songs). The icon shows the 4G+ but with the X for No Internet. Phonecalls and MMS work fine.
Update 6/8/20 (temporary-solution found!)
From some playing around I found a solution that seemed to fix it for me.
1. Turn the phone off
2. Remove the SIM card tray
3. Turn the phone on (Without the sim card tray inserted)
4. Re-insert the sim card tray after the phone is all properly loaded
Update: 9/8/2020
Cellular stopped working again

Same problem as you.
Hey there,
I am having the same problem as you as well. After i had updated to the latest, my internet has stop working. It shows 4g,but with an x below. However, i am able to use sms, and phonecalls. I tried toggling the mobile data, it worked for a while. But after a few mins, it went back to the same. Any way to go back to the previous update, please help.

No, I haven't setup my DNS with the private DNS feature but the Wifi menu, and I'm not sure if that even applies to cellular data anyway.
