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.

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.

[Q] HTC Desire HD WiFi not connecting at house but does everywhere else

Hello. My phone connects when I go to other people's houses or at school, but not at my house. My router is set up with a WiFi access list so that you need to enter the MAC address before being allowed to even see the network. I have triple checked that the WiFi MAC address from my phone is entered correctly as I did everything else. Does anyone have some advice?
I appreciate everyone's time!

Make sure the channel is set to one which your device supports.

I downloaded an app called wifi analyzer; will that help me find which channel to set it to? How do I know which are supported.

Go to the wifi settings (on your device) and see what channel it is set to (usually under regulatory domain).

maybe you should set the maximum number of channels, otherwise some routers might be excluded.
controls which channel is your router and then try to configure the connection manually.

Sorry for the late reply; I have been pretty busy.
I tried a variety of different channels but none of them seem to work. I had seen that the phone does not work on Channel 13 but that did not seem to be the problem. I have also tried changing the security password type on my router but that did not work either. Are there any other suggestions? Thank you again.

your router is wireless network is to advanced for phone allow you network to be seen and just have to enter a password to work it will work been there
ps when it works hit thanks please

I'm assuming you did... but just in case, you did hit the "Wifi Protected Setup" on the phone right?
I swear i'm not trying to make you sound like an idiot, but we all have our "oh damn i forgot about that" moments, know what i mean? lol

Lol no problem. But yes I did do that

i'm also assuming then that you took ALL security off your network, leaving it open with no password, and that didnt work either.
past that, I don't know what to tell you. some routers are better than others.... maybe yours just hates you?

charge wont pick up my wifi

I got my wife a droid charge today which she loves but for some reason the wireless tether from my rezound will not show up on her wifi settings. many other devices detect it including my laptop and even iphones i have unlimited wireless tethering. Im no stranger to rooting so maybe kernel related? I dont know but it dont make sense. Let me stress i dont want to tether with the charge i want it to pick up my rezounds wifi. any suggestions? thanks

Try to manually put in the SSID and other network info?

thanks but im not real sure how to do that

Go to Settings>Wireless>Wifi, and there should be an option to add a network/connection. I can get more detailed info once I get home, but there is a way to enter in the connection info even if the phone doesn't see the network.
I've also heard of incompatibilities between various wireless chips that could also be to blame, though you'd have to find someone else to duplicate this to confirm that is the case.

If you have DHCP it should fill itself out. Just enter your SSID and hope for the best.

I have had the same problem. When using WirelessTether on my charge I can not get an Samsung Captivate or a HTC incredible to see my SSID..but the laptop connects fine. Anyone know why I cant get the phones to see/connect to my droid charge. I have tried entering info manually on both devices to no avail. Anyone know why it doesnt work?

Judging from the above posts i think we can agree that we found another crap that Samsung took on this phone

I think I've only had one issue not being able to connect to a network. I connect to a large number of WiFi networks and seem to always get a good link (although the WiFi performance isn't all that great- 15mbps one-way.) To resolve the issue I had I think I just pulled the battery from the phone. It may not always be the phone- some access points and routers generally don't work that well, only support some encryption types, fail even though it broadcasts SSID, can drop links, won't authenticate, etc. I deal with bad wireless far more than I care to and I generally quit messing around and run certain model routers with 3rd party firmware because I'm tired of headaches.
Make sure you can connect to your router with other devices.
Power cycle your router.
Pull the battery on the phone.
Enter in the information into Wireless settings. If information is there already, delete the network and re-enter the info.
You can also download WiFi Analyzer from Market and the WiFi Connector Library and just use WiFi Analyzer to manage your networks.
Also, make sure your router is using an unused channel.

thanks but i dont have a router i got unlimitws wireless tether (legally) i run all my devices including laptop from it but this damn charge wont recognize it

What device is the providing the signal? Try changing encryption type.
Sent from my SCH-I510 using XDA App

You shouldn't have to enter in any IP/Subnet info. With Wifi turned on, go into Wireless and Networks > Wifi. There should be an option to add a new network. From there, you would just have to enter in the SSID of the network, the encryption type (if any), and passkey (if you're using encryption).

What happened to WPS?

It seems to have vanished in ICS. How do you connect to a you password protected home router? With gingerbread, I would use the wps button connection to connect automatically but I see no such configuration in wifi settings in ics.

Usually when I connect to a password protected router, I enter the password.......,

You have never used wps or other easy wireless configuration? I had it on my phone with gingerbread but lost it with ics.

Most people prefer a more secure wifi access method.

It seems most people here have difficulty identifying the question asked by the OP.

The OP is referring to Wifi Protected Setup. Yes i think it was removed.
While it certainly made wifi security easy, it is my suggestion not to use WPS as out was cracked back around December.

No it was answered in the first reply. At least the way he worded his question.
My reply was pointing out the same fact as the other poster. The fact that WPS is completely unsecured since Dec. So most people don't even try to use it hence why its not talked/cared about much.

You should setup your wireless networking gear (home router and all wifi devices) to use WPA2-PSK and a strong passphrase. When everything else is in place, you can input the same passphrase on the wifi setup dialog that shows up when you select your home network in the TF101 WiFi preferences screen.

As stated by other posters, WPS is utterly insecure and it should never ever be relied upon for proper WiFi security.
That said, I don't recall WPS ever being supported on the TF101 even under Honeycomb (I could be mistaken, though, since my WiFi network equipment doesn't support it).

I happened to be goofing off with my WiFi the other day and I saw that when you go to Settings -> WiFi -> Advanced (in the top right corner) there is in fact an option to use WPS on the tablet with ICS. Find your router name, tap on it, then a little check box with show advanced options. Select WPS and choose button. Then hit the button on the router. Worked for me just fine.
Here's a screenshot: (For whatever reason, I can't upload an image...)

Grow a sense of humor guys, I was making a funny.
On a more serious note, I don't use wps. I use wpa2 and mac filtering.

May I ask why WPS is so insecure? My router has a WPA2 protected SSID, but I used wps to setup my wireless printer. It seems to only be" insecure" when it's enabled and looking for a device, which is timed to be on for no more than 2 minutes. I don't think vultures are waiting for those two minutes to connect to your router. Or is there another danger?

this is like kindergarten chit-chat. totaly lame thread.
WPS is NOT a replacement of WPA it's not a security feature at all!
if you have WPS on ON ROUTER you still need to choose open/wep/wpa/wpa2
as the name could suggest, S stands for Setup and that's what it is. WPS will connect you without need to search for the network in the list of available networks, or even knowing the network name and if there is password, it will fill it in for you. it's an easy setup where you don't need to know password or the name of the wifi network you are connecting to.
another thing. you can't talk about vulnerability in reference to the wifi client - phone. it's the router which is vulnerable. If your car has weak remote central locking, throwing away your remote key transmitter will not make it much safer.
saying ICS doesn't have WPS because it's hackable is wrong. if a coffee place desides to use WPS their net is hackable, it's their concern. I still want to be able to use it as this safety issue doesn't affect me as a wifi client.
and thought ICS has this complicated way to get to the WPS, it's missing the point of WPS as you need to know which wifi you are connecting to, and click many times to get to the option. not easy setup at all. and the indicator of WPS availability is missing too. If I came to a coffee place and saw the icon I told them to keep their password and push the button instead. now I don't know if they have WPS.
So there is still an issue.
But maybe the ICS phone is listening for WPS all the time I didn't test this.
EP: your question is in place.
if it's your network, make sure you update router to latest firmware, as this vulnerability has been already addressed in most of the routers. Or keep it OFF until they'll make update to it.
it is NOT only those two minutes after you push the WPS button, but it's hackable all the time.
WPS can be used different ways, you can enter pin of client to be allowed in into router, or pin of router into client, or just push the button and no pin at all.
so the pin works all the time, that would still be fine, but a certain template was found in those pins, which brought the possible number of choices low enough to use brutal force attack to get the correct pin. that's the safety issue. nothing to do with the phone.

Wont connect to wifi?

ok this may be a simple thing im overlooking. at my work whenever i connect to wifi it asks for identity then password. with the photon it never asks for identity or i cant find a option to type the identity in therefore i cannot connect to wifi at work. it really sux cause i get bad coverage at work and rely on wifi. i know on some HTC phones i had in the past it would make me set up a screen lock for some reason before connecting, not sure if the motorola has some trick too but i cant figure this out and sprint customer care isnt much help either. anyone have any ideas?

Unfortunately you didn't specify the type of wifi your work uses?
It's obviously something beyond WPA/2... So what is it?
I found this thread on PEAP. See post #5 for a potential solution... Perhaps this will help with PEAP and other types? I'm not very familiar with the more advanced, enterprise forms of wifi unfortunately.

the main one i always connect to just says 802.1? some do say wpa and wep .. sorry im not familiar with the terminology of wifi networks. i just know i always hit connect and type the identity and password and im on.

ill try that app mentioned in the link.. thanks!

that worked! first phone ive owned were i needed a app to connect to a wifi network..
