School wifi problem

Just got my Samsung Captivate about a month and I got my wifi connected to the school network, but when i open the broswer or any apps need internet i didnt get any connections? at the first week it works.. and when connecting to the school wifi it should be come out with the school login page,, then the internet will work.. however the wifi is connected doesnt matter how strong the wifi singal is.. it just cant load and cant bring me to the login page..
I really need help..
and the wifi works everywhere.. except my school...
btw my friends iphone 3gs works..

I am also at college and have had the same problem. the best reason I have found is the phone itself. half of our wifi is an older standard that does not work on the phone. it shows up as wep and i can not get it to recognize it as 802.1x . in my tinkering I have also messed up the wifi that was working.
long story short it probably won't work. I have spent a long time trying to get it to work with no luck

Hello to both of you,
I also attend a college with an 802.1x connection and the captivate supports most of these networks; however you will probably need to configure the network settings manually (usually retrievable on your schools IT site). If you dont mind digging up your settings I would love to check to see if I can configure your phone.

FYI, you might be having a problem similar to what's seen in this post.

I definitely had this problem today. It appeared connected but no web pages would load. Going to have to investigate further. Why can't things just work

I know my school recently implemented some new security certificates that you must agree to before logging in, has anything like that changed for you? My wife's Aria is running 2.2 and can log into the school network, but my captivate cannot. It is frustrating I know.

Seems some colleges and universities are noticing issues with android devices letting the DHCP leases to expire but keeps using the IP address assigned instead of requesting a new one.
See the following links.

I actually have similar issues with my Belkin wireless router at home. My laptops and other wireless devices have no problems connecting or re-connecting but the Captivate just refuses to re-connect after the connection was terminated. Even after resetting the router, the phone just keeps trying to use the same IP address for some reason.
The only way I could get it to reconnect is to either reboot the phone or to remove the AP entry which is a pain especially if you have wireless passwords.
Hopefully someone with better insight into how Eclair and Froyo handles WiFi can come up with some fix.

more solutions?

I believe the new 2.2 firmware solves this issue. I too am at College and my captivate FAILS to actually access the internet through wifi unless I statically assigned the IP.
I just updated to Froyo and it connected instantly. I'll have to do more testing to make sure, but I think Samsung finally fixed it.

captivate wifi issue at school
i just got Galaxy S (Captivate) and wi-fi is giving trouble.
when i tried at a university campus, it gives error and says can't open and try again later. it is like, i get connected to the network, IP and DNS and everything is generated. But when i open browser to open a website, instead of taking me to login page it gives the above error.
here is what i get when i try to open a website.
'web page not available'. the page might be temporarily down or it may have been moved permanently to new address.
here are some suggestions:
- check to make sure device has signal and data connection. (I made sure it is connected to wifi)
- reload page later. (i tried after 5 mins, same result)
- view cached copy from google. (doesn't work either)
i am not able to understand why is this happening. i tried restarting the phone after connecting to wifi but no luck. any pointers?

Sounds like they use a portal system which requires logon and doesn't play nice with the Captivate's browser. Unfortunately many such portal systems are written poorly and I've even seen some that only work with Internet Explorer.
You could try a different browser on the Captivate. Dolphin allows spoofing assorted User Agents, which might help.

Hey guys, I have the same problem connecting to m school's network login page. It would say connected but the website always says cant be found. But the good news is that I found a way to connect to it manually! What you need is your captivate and friends iphone 4 or 3gs. First have use your friends iphone to connect to the wifi and then go into wifi settings. You should see 2 DNS address, Ip address, netmask (subnet mask) and router address. Now jot those addresses down except the ip address. Go to settings->wireless and network->Wi-Fi settings->now tap the bottom left button under the samsung logo and click advanced. Now check use static ip. Do not enter anything for your ip address just yet (we will do this last). Now enter router address into gateway, subnet mask into netmask, DNS1 to DNS1 and DNS2 to DNS2. ok when you are done click back and tap the network you want to connect to. Once you are connected jot down your ip address by taping the network once more. now go back to where the static ip was and input the ip address you just jot down into the ip address underneath use static ip. Disconnect and reconnect to the desired network. You may have to do this a few times or reboot your phone. This has been working for me so far around different buildings but with the same school network connection. I hope this helps cheers!

Yeah, my school uses the Bradford dissovable agent. Funny thing is, some connections work perfectly, others not at all. Technically none should work, and sometimes I feel that maybe I should tell them that sometimes somehow it is possible to bypass the whole agent thing- but why rock the boat just yet

Does it need a proxy to work? If so, this app is amazing.
http://forum.xda-developers.com/showthread.php?t=766569

I figured it out a month ago, and it is actually petty easy. But you really have to change ip address manually, usually just the last number.

Can't connect to internet even though connected to router

hi i am in need of a lot of help here. on sunday i decided to search something on the internet and i kept getting web page not available on every page i went on... the thing is according to my phone it was connected to my router and was displaying a wifi signal bars and everything.. all my other devices are working as usual but on my phone it will connect the internet will work for a minute or two then i wont be able to connect again till i reboot my phone.
any info would be appreciated.
Zachary

sounds more like a router problem to me than a phone problem,try connecting it to a diff network.does the same happen?

What router are you using? Sounds like a router issue to me.
First thing to try is always a router power cycle. They can occasionally go nuts. Unplug for 30 seconds.
Second thing to try, log onto your router, and see what wifi protocols are set to. If it's set to B/G/N combined, try setting to G/N. (assuming you are not using B anymore!) If not using B or N, set it to G.
Third thing to try, disable Wireless Multimedia Extensions (WMM). Not sure where it'll be in you're router.

Have another thing to try...
You might not picking up gateway information from the router. The solution could be to configure a static IP address instead of using DHCP.
To do this do the following:
Go into Settings, then ‘Wireless & networks’ then ‘Wi-Fi settings’ then press 'menu' and select 'advanced', scroll down and select the 'static ip' box.
In the ‘IP address’ box enter the same IP address which is shown higher up the same form.
In the ‘Gateway’ box you will need to put the IP address of your router. To find this out I opened a command prompt window on a PC on the same network and typed ipconfig. This will give you a Default gateway address which is what you need.
In the the ‘Network prefix length’ box put 24 (this assumes the subnet mask from ipconfig is 255.255.255.0)
Finally in the DNS 1 box put the same IP you put in the Gateway box.
Now click Save, disconnect and reconnect from the network and when you are reconnected you should have internet access.

Erm, guys - you jumped in at the deep end, surely a restart is the first thing that should be tried.
A) Restart router
B) If not fixed, restart phone
C) Do what the above say

i have already done a power cycle on my phone and router..
i tried to set up astatic ip but now whenever i try to connect it says disconnected after trying to obtain ip address
help please....excuse my ignorance if i missed anyhting
EDIT: managed to get DNS to work will test and see and update you

HTC One X Stuck on "Obtaining IP address"

My phone keeps cycling obtaining IP address without ever getting one on my home network. It has previously worked fine on my home network for a little over a month now and the problem suddenly started yesterday. No other devices on my WiFi network has the problem. Phone and router were rebooted, problem continues.
Any ideas?

That used to happen to me all the time on my Kindle Fire, particularly after flashing a new rom. The fix was setting the date and time to automatic, but that may not apply here.

I've found this happens too intermittently. It's a real pain. happened on a number of different custom ROMs.
other times it will say the network isn't in range, even though I know it is.

Depends on your network
DNS you get from your ISP, check router for it.
Prefix should be 24
IP whatever you set in the router ie 192.168.1.125
Gateway is whatever your router is ie 192.168.1.1
Google setting up static ip network it will help explain it and over at ddwrt they have pictures to help... very easy stuff. PM if you want/need help

You can try to turn off auto-DLNA..
It may causing device to configured itself under private ip range..

Same problem. Using stock rom. Tried static ip but not works.
This problem is a software problem? Or hardware?

This doesn't apply to my device now but on my previous HTC this would happen quite frequently I think it's more of a software bug then firmware it would seem that the drivers for the antenna are hit or miss

I had this issue and my phone wouldn't connect to any router "obtaining ip address" forever. Mind you my phone was 5days old, so took it right back to Rogers for a new exchange. My HOX is now perfect and connects to all wifi without issues.

Did you possibly enter the wrong spa password, then re enter it correctly and now you are having this problem?
If so, try this ... works on most Androids.
Click where it says obtaining IP address, the press "Forget"
Turn off Wifi.
Go Into Hone Settings > Power and disable Fast Boot.
Now power off the phone ...not restart.
Leave the phone off six minutes and not a moment less.
Then power up and try again.
Be careful to enter your wpa password correctly on the first try.
If still same problem try rebooting router.
Also consider installing SmartSync Disabler which can be found here on xda and at the google play store.
That app should solve the remaking wifi annoyance affecting these one x phones

the employer blocked the WIFI from employees (obtaining the ip address issue)
we cant access the WIFI in the hotel at where we work and although there are a password you put at the hotel's WIFI website but they did something lately to all of us and it is when any of the staff open the WIFI on his mobile it just keep showing obtaining IP address and no result so if you guys could help me in this and do i have to get a new phone or to try hiding my IP i tried a lot of apps but no way plz help

PEAP Wifi

Anyone have luck connecting to a PEAP AP with credentials, I tried some apps that don't seem to work? I can't connect at my University.
Photon Q

I haven't been able to join my work's network with the photon q either. Someone in my thread suggested "explicitly trusting" the certificate but I haven't had the chance to see if the network team is competent enough to do that.
Other people at work also have other motorola phones with ICS so I'll ask them if they can connect. I haven't seen any other devices struggle like the photon q. It just constantly says connecting and then giving up. I can manually set everything correctly and it doesn't matter, if I don't manually create the profile it never asks for the rest of the information.
I'm really at a loss but if sprint's LTE announcements hold true in a couple weeks it may not even matter (assuming an LTE signal is even remotely discoverable).

same for me, I'm just hoping for an JB update soon(yeah right) cause LTE will never be here, but we don't even have wimax. thanks

I know... I do miss my evo shift's wimax, sometimes my work network was so crappy that I'd just wirelessly tether to my phone and got much better speeds.
Interesting that you noted JB. Is the general consensus that Motorola is rather slow about releasing OS updates? My co-worker with the Droid 4 just got ICS a few weeks ago while the Galaxy Nexus has been starting to get JB on sprint.

Successful connect to EAP
Well, my university has 802.1x EAP for wifi encryption. I was unable to connect from my Photon Q using the wifi settings. I have, however, found a workaround. It consists of using this app "WiFi Connection Manager" (Sorry I can't post the link)
I added the network manually through this app, and my phone connects to the network automatically.
Ill write down the steps for my University's network:
1) Click on the app "WiFi Manager"
2) Click on the menu button inside the app
3) "Manual Add Network"
4)Put in the credentials
5) Click Add
6) the phone should connect to the Enterprise network now.
Hopefully it works for everyone who needs it.

I'll have to give this a shot when I go to work tomorrow, I had the network director fiddling with my phone for a while and checking the AP manager and they just weren't talking properly. We loaded our certificate onto the phone as well and that had no effect.
EDIT: IT WORKED. Oddly enough the APs showed up as WPA/WPA2 PSK in the program, but when I manually created the profile with the settings that I know are correct it did eventually connect and work.

good work guys, my univeristy just switched over to peap and this thread helped.

Thanks, guys. Once I had gotten my Photon Q back in late September, I was able to connect to my Universities' wi-fi, although it was kind of a pain because I had to delete and re-create the network profile a few times before it would work. A few weeks ago, though, we had a security certificate expire, and so for the past three weeks I've been unable to connect to our wi-fi. Using the WiFi Connection Manager to manually create the profile worked like a charm though!
In case people are curious, our Universities wi-fi is 802.1X EAP/PEAP using MSCHAPv2 as Phase 2 authentication.

Thanks for this thread, and thanks for this post. I had the same thing happen. My work wifi showed WPA/WPA2, ect., and I could not enter my credentials. We also have an open wifi, which the program kept logging into automatically, but it doesn't work for me because it doesn't allow ssl. So, I had to delete the open network, go to the settings to filter the scan to ignore open networks, then add the secure network manually with all the credentials entered. Then it worked.

WiFi?

Hi,
Why am I getting this notification for the 1st time in approx 2 months that have got a OPO, despite that am connected to WiFi?
Hoping to hear from you experts.
Thanks.

This sort of thing normally pops up when the WiFi network wants you to go to some sort of page, this is usually for a login to free WiFi hotspots, I assume this Dlink is your WiFi? Perhaps it wants you to open this page to change a configuration or login. This doesn't seem to be Android related at all but more to do with your router, could you try tapping on the notification and screenshot the page it opens, if any.

He's right. This looks like a router setting that you might have turned on like guest mode.

This is a router setting then, that page is some sort of login. Perhaps guest mode has been enabled on your router? Try this:
Settings>Wi-Fi>Modify Network>Show advanced options> Change DHCP to Static. Here, find the box that says Gateway and note the IP here. Now change Static back to DHCP and close this menu.
Go into the browser on your OPO and put in this Gateway IP, this will take you to the router config. The login for this is usually on the bottom of the router, otherwise the default can be found by searching the router model number, try finding a guest mode setting and turning it off - I really don't know... You can also change your WiFi name and password here if you like
I can't really help you any more than that.

1. Changed router's password.
2. Guests mode is Off.
3. All apps working with WiFi except GMail and GPS.
4. Still see the notification.
5. Should WPS be Enabled, it is disabled at the moment?
6. You don't recommend a factory reset what about a re flash of 30 OR?
Thanks.

Your phone is working fine, it seems you have triggered some sort of bug in Android's WIFI login detection.
The system works by accessing DNS and check if the resulting IP is owned by google.com or some network-internal redirection/replacement by a login page.
Now, the IP 173.194.35.96 is owned by Google, so the DNS lookup obviously worked perfectly but for some reason the phone gets an unexpected answer from that server. Which makes me guess to one of the 2 following options:
a) one of the computers in your network is infected and Google keeps showing the "Prove you're human" captcha window on requests.
b) your provider is replacing failed DNS lookups with it's own "helper" page which for some reason is making Android trip. If possible, change the DNS servers in your router to either OpenDNS or Google DNS.

That's entirely your choice. However I would only recommend enabling it if it's the "Push to WPS" method and not constantly on - WPS is broken and depending on your router it takes between 1 to 10'000 attempts (1 second to ~ 2 hours) to break into your WIFI. Not good!
