Captivate & 802.1x

I've had the captivate about 24 hours now and dig it. I've rooted it and remove the att bloatware (per titanium backup), I've also performed a backup using Rom Manager.
I'm having trouble getting it up and running on an enterprise wireless what uses 802.1x PEAP authentication. I can get through all the auth. steps, and the device is assigned an IP, but I am unable to do anything that requires an internet connection; browser, market, etc.
Has anyone else ran into this issue?
*****EDIT*****
sigh i just realized that this is in the wrong area, it should have been over in development...i'm an idiot

I had a similar problem on a WEP-encrypted network, which I fixed by setting a static IP on the phone and then setting it back to DHCP (the correct setting). However, your problem could be entirely different than mine (not that I even am sure what my problem was, just that I fixed it!)
Best of luck!

Having the same problem on enterprise access points regardless of encryption. Home wifi netwroks work great (open and WPA2). Enterprise APs (open and WEP) connect and give me an IP, but will not transfer data. Think its a driver issue with the Wifi, it happens on every captivate ive tested, and seems to be more widespread than the GPS issue.

I have had the same issue with my work at work. I can get it to connect and get a ip but can not pass any data.

Had the same problem at work. Luckily I'm an admin and figured mine out. Our monowall portal was the issue. I can give a detailed answer for my problem tomorrow when I get to work.
I actually had the cap wiped to go back, then I literally figured out the problem. Thanks go out to my team mate for helping me talk through this.

This sounds more like your network not being allowing your device rather then the device having an issue.

it's been frustrating as I know two other guys with android devices that didn't have an issue. one is a droid eris running 2.1 and the other is a nexus one running 2.2.

Worked closely with my highly experienced network admin in my dept. for an afternoon (we had some time to kill). He checked the firewall and dhcp servers, ran packet traces, etc.
With what I'm experiencing, its the device. These wifi networks we use with Cisco APs are completely wide-open. All other phones and mobile devices have always worked great for years. We rely on this network for many custom applications and mobile tools.
Once the dhcp server leases an address, it seems like the radio stack hangs, and the device ceases communication. Here's an older thread on the exact issue over at androidfouroms: http://androidforums.com/samsung-captivate/130403-wifi-terrible.html
I have tested multiple new unmodified captivates and the issue is identical accross the board.

Now that I am at work, and have coffee in me and not beer, I will go through the problem I had with miCap and works wireless. Due to my skeptical ways, I will be semi vague for security purposes. On with it.
When I originally got miCap (pet name for it) I was able to access our public wifi. It allowed me into the public portal to agree to terms. I played a little bit on it, but wanted to see if I could access our private wifi. I got in the private no problem. But after that I never was able to get back on to our public. It did the same thing as I've read. It got an ip no problem (via dhcp) and acted like all was well. No browser, or ap could get a connection. The phone would not switch over to 3g to get info.
Armed with ip and mac address, my co-worker and I started to did through our monowall. ( He also has a cap that had no issues on public or private). We try tried reserving the ip for miCap, didn't work. We tried static ip, didn't work. I spent the morning completely wiping miCap to get it back to return worthy.
This was when I decided on last ditch effort.
Our ap's are cisco's that connect into monowall. I got into monowall and dug around. I found that with in the captive portal (how fitting) that the ip/mac associated with my phone hadn't checked in for 8 days. Even though I tried everyday. I deleted the entry to the phone there and suddenly my phone was getting access again.
Now I understand that this may not help everyone, because setups vary from place to place. But digging deeper into configurations at the access points may be what is needed. Do I think the phone had nothing to do with it? No, I think it helped aggravate the problem.
We have had problems with the Intel 3945abg chipsets with the same exact setup. That problem was fixed with driver updates on the laptops.
sorry for the long winded reply.

So in a nut shell you deleted the DNS entry for that ip/mac in the firewall and you are working.

Essentially yes. But it is not listed like that in the portal. Hmmm. I wonder about the combo of dhcp/dns being the culprit.

I was able to resolve this issue by changing my connection settings from DHCP to static for the Cisco APs.
Installing WiFi Buddy from the market allowed me to access these connection settings.
I just used an address from our static IP pool.
Manually set IP, subnet, gateway, and DNS, and now im finally rolling on our enterprise wifi network

I sent a help ticket into samsung; maybe if enough folks do we can get it on their radar.

you can set the ip manually with out an app. When on the wifi screen, hit menu-advanced. This is a good time to set the wi-fi sleep policy also.

UPDATE
So I flashed the i9000 Eclair rom last night, and when I got into work today I can connect and use the wifi here. So looks like something AT&T buggered up, big surprise there, when they "customized" the captivate.

As much as I normally love blaming AT&T for problems, that can't be done here. My Captivate (running Stock Firmware) connects just fine to my work network. We use 802.1x with PEAP/MSCHAPv2 for authentication.

Anyone been able to connect at over 802.11b speeds while connected to an 802.1x network? I show connections at G and N speeds on my WPA2 network but nothing over 11Mbps on 802.1x.

Hi,
I am also having problems with my work wifi network.
It is 802.1x, on TTLS/PAP it also requires a thawte premium server ca certificate insalled.
Is there any way to connect this kind of networks?
With my previous iphone 3g it was taking only 4-5 seconds.

Faceniff anyone?

Has anyone tried faceniff on the atrix yet?

yeah it works. lol.

Such a vague post. Whats it all about? Details maaan!

theres always google

I meant on the Atrix which is the forum I am posting in

It works well on the Atrix. I have it and it does seem to work.

Does anyone know it works on WPA and WPA2? Are they forcing the client re-associate to the AP to sniff the initial key negotiation?

Works on WPA2 here. Does not work on EAP though I don't think.

Hmmm does anyone here has an unlocked version? 0.o

Works great for me *edit: on the Atrix*. I asked the dev about putting the unlocked on Market or Amazon (dont like paypal). He said it was removed from the Market and he will look into Amazon.

If he releases some code(maybe he already has, haven't looked), this could open likes of similar apps. I especially like the idea of an Atrix as a wireless monitoring device since it has 5ghz, unlike almost all other phones.

I bought it and got it unlocked. This is more for curiosity's sake than actually hacking. I live out in the country. Not much for open wifi out here.
Scott

I went to a Starbucks today after getting the app, and I couldn't get it to work there.
Not sure if it has to do with the AT&T Wifi at starbucks, but I'm going to do more testing with it.

Did you try stealth mode, I guess some routers are built to monitor that kind of intrusion and stealth mode is the work around

Faceniff has nothing to do with open vs WEP vs WPA vs WPA2 encryption on the network afaik(I haven't used it, but I read about it). It wont break encryption. My guess is that its doing a simple ARP poisoning attack, routing all network traffic through your phone before it goes out the router, then just filtering for unencrypted facebook/tsitter/etc. packets.
This has been around for years. What's new is that its been ported to a mobile phone and been made accessible to the masses.
Be careful using this guys, your network traffic leaves a trace, and I'm not sure if facesniff spoofs your mac address. You could get in big trouble if you get caught.

I understand that you already have to be connected to the AP to do this but... as I understand it with WPA and WPA2 they negotiate session keys so that each connection uses a different key. Hence you cant decrypt another persons traffic. The key is negotiated in the beginning and if you can capture that negotiation, then you can decrypt the traffic.
Does faceniff only monitor new connections and then see if they log into one of those sites? or does it actively try and disassociate people from the AP so they have to reconnect.

Was using it on my home wifi. Was able to hack into mine and my gfs facebook accounts. Then i monitored my neighbors open wifi (tard) and was able to get into his. Told him to put a password on his wifi because of security. I think this is a real eye opener into the world of internet security. Really interesting app. Pretty scary. But yea, using this at school is a bad idea. I was just doing some packet sniffing at college and i got a nasty email saying that if i was doing anything nefarious i could be expelled. So remember: USE STEALTH =)

Hey there,
could someone send me a PM where to get this app.
THX!

No poisoning needed. Wifi works the same as a hub. If you're associated to the network, you'll see all the traffic. Now there are ways to try to stop this, ap isolation, and whatnot, but it's radio, so there's really no way around it.

[Q] Able to connect to many different WiFi Networks except school ones

Hello all.
I can connect my Nexus 10 to my home wifi (password protected), my girlfriend's home wifi (password protected), and the wifi at public places (I've only tried ones without passwords so far). My only problem is when using my University's Wifi. They have one that you use with an account and password, and one that is free (though you need to sign in using an email via a website. Kinda like hotels).
This is surprising to me because I have a Galaxy Nexus running the same OS (4.2.1) and it can connect just fine. When my N10 tries to connect, it says "connecting" for a second or two, and then it just says "Saved" but never "connected" and it never shows a wifi connected symbol at the top right.
I have read multiple posts about wifi problems from 4.2 but couldn't find any specifically buggy wifi problems like this. Have any of you heard of this or a solution to it? Any help would be appreciated!

Have you tried a reboot? Also check to see if your frequency band is set to auto under advanced wifi settings.
Gotta love university security and logins... they can't leave stuff simple

Oh yes. I have rebooted many times and tried using auto, as well as both frequency bands separately.

Hmmm...are you on stock?

Yes I am. Stock on both my Gnex and N10.

I wonder if using a third party wireless manager would help. Search the PlayStore and try one or two. Before you do that, go into your normal WiFi settings and click "forget this network" on the university one.

Hi there,
I work at a University in the midlands and had the same/similar problem. It's to do with certificate revocation in Jellybean (and also the latest ios my colleague tells me). For example on my Nexus 10 I was able to see the network and obtain an ip address but the webpage where you login wouldn't redirect or load. I don't know what Uni you go to but we are advising people to give the IT dept a call and give them your mac address and they can create a fixed profile.
Hope this helps

I'll definitely try the third party app. As for telling the n10 to forget the WiFi, I tried that many times too
Well that's why I mentioned my gnexus because they're the same android versions so if it works on one it should on the N10. I actually work for tech support at my university and my boss couldn't figure it out or suggest a process like you described. Thanks, though!

Oh yeah you did mention your Galaxy Nexus, my bad! let us know how you get on with the third party app. You could try giving your N10 a static or reserved IP if you have access, as a workaround!

Hey guys,
I'm from France and had such trouble with my Motorola Milestone and my HTC HD2 (and friends too with Samsung Galaxy S2 and Sony Ericsson Xperia Active) with my school's network. If it's an Eduroam network, try Eduroam Fixer from PlayStore, it helped all of us except one Samsung Galaxy S2. Give it a try

Make sure you have the EAP set correctly and check if you need a phase 2 authentication. For example, here at UofM we use PEAP for eap and mchapv2 for the phase 2. If you don't have details like these, your tablet won't connect even if you have the proper login.
You will find them at the top of the page you use to login to a secure network.
Hope this helps!

Yes, that is exactly how the secure WiFi is set up at my University, too! What should I do in this case?

Edit: Nvm, Just noticed this was already tried
I had a similar issue with my One XL. It was a frequency issue. I switched it from 5ghz to auto and all was good.

Okay so I found out that my N10 is able to connect to the exact same WiFi network when in another building. I believe there is just an issue connecting to the specific router used at a computer lab. Will update when/if a resolution arises for that lab.

WiFi problems (4.2.1)

OK this is really pissing me off. Everyone time I go on my nexus device it doesn't automatically connect to the WiFi.. I have to either disable the WiFi and reenable it. Or just click on my network and click connect (it says its saved but doesn't automatically connect when I turn on my device), i tried everything from forgetting every saved network, restarting me device, ect, and its not my routers problem, my DNA connects automatically when I turn it on. Any of you guys had this problem? If so what did you do to fix it?

Hi,
I share the same problem. Upon a reboot, it will work normally for a while.
Once they symptoms starts, it will refuse to connect most of the time. When it does connect, it will disconnect within a couple of minutes. WPS wont respond either. toggle wifi/airplane mode does not work either.
The only way is to reboot.
However, I did have some findings but couldnt get it fixed! Do this and test if it works for you as well:
Go to terminal (needs to be rooted device):
Simply select the "Take wifilock/B]" option and it will stay connected!
Release it and it will get disconnected and back to the same issue.
Hopefully some experts can give us some pointers?

Temporary fix
I have the same problem. This is what i did to fix it: Settings- Wifi settings- advanced- switch always on to Never, reboot in recovery, clear cache, reboot your device and go back and turn Wifi back to Always on. this is a temporary fix because if you reboot or shutdown your device, you will need to redo the steps. this is a known problem with google's 4.2 jellybean. we need an update soon!
hope it helps you.

Thanks for your help

It won't be much comfort to you, but remember that "it takes two to tango".
Yeah, there's IEEE standards for all of this stuff. Do interop problems still happen? All the frigging time, every day. Sure it is maddening.
And sometimes the problems only manifest themselves with an exact pair of firmware(s) releases between the AP and the client device. I had a WiFi router that would gladly talk to four or five unique types of devices; on the sixth - an Android phone - it would associate & authenticate successfully, but the client device would never get an IP address.
That sure sounds like a problem with the phone, doesn't it?
How did I fix the problem? I upgraded the firmware ... on the router !
Sometimes problems with intermittent connections can be rectified by fooling with things that you might think have no bearing on the problem. For instance, some routers will accept connections in A/B/G/N mode. Do you need all of those? If not, simplify your router's behaviors by disabling non-essential features, e.g. select G-only or N-only.
That's just an example - but the point is that the fewer behaviors either of the devices engage in, the lower the probability that the bug which is shared between them will get expressed.
So, you can either fool around with both devices, only one of them - changing one setting at a time to see if that alters the behavior you observe, or you can throw one device away and start all over with new combinations of devices. The router probably has more knobs which can be turned than the phone does (unless it's not your router, or you don't control it).
Good luck

[Q] wifi and firewall

hi, I just got a Galaxy note 4, I can connect to wifi everwhere but not at work. I get error that password is incorrect, I have the same password so I know my password. My stepson has a galaxy s5 and has no problem connection. I actually just returned my first phone after trying 5 days to get it connect at work. Both Comcast box and firewall have been reset. So I am not sure where to go stepson suggest change to developer operating system. I have tried safe mode, soft reset and factory reset to no luck.
This is last resort - before I return and get a different brand/model phone

if you can connect everywhere except work its your work problem. some workplaces use cisco and proprietary protocols to login to wifi after connection. if your workplace does that you will not be able to connect. no phone will. ask your work wifi to use WPA2 with AES instead of some proprietary protocol for wifi. if your son has installed some non standard rom to get his s5 to connect you will need to buy an s5 and do the same.

Response from my IT guys - -they are very helpful since this is a personal phone and not company issued.
I don't have a good reason for this one device to have a problem connecting to this one network. I believe we have eliminated common errors such as mistyped or incorrect password, since you have personally been able to connect other devices without issue. This also eliminates the possibility of a 1-time setup or authorization requirement, as you did not need that for the other devices. I will need to look into whether there could be a technological incompatibility between the two devices.
We will look into this further and have to get back to you.

We have a WPA2. We have people come visit all the time and have them connect.
I am just wondering in there is something in this phone operating system that is more technological updated than the systems we are using and could be the problem

I still would try to use Wifi Protected Setup. It is software depended and Note 4 is capable of using WPS while many others not. It is possible that software in Note 4 sensing that access point has that feature and requesting it. Im not network specialist but I setup few laptops for my friends. They were using Dell Vostro laptops and by default they required using WPS to connect to home network. Once that feature was disabled they connected with no problem using user password.

not possible since i have connected to both WPA2-PSK AES and WPA2-EAP AES systems. EAP requires a username/password instead of just a password.
the only system i have not been able to connect to is a WPA-CKIP and WPA2-CKIP which is a cisco proprietary protocol.

Hi all,
My Phone has connected to the company wifi. I was searching for an infinity hot spot since I am an infinity customer and was scanning and then I am connected to the company wifi. Then it began to do all these updates and I did nothing to prompt this. (weird since it can connect at home and this did not happen) I have been in contact with Samsung and have been explaining my issue - part of their process is you need to enter model and serial number- is it possible for them to track my phone - I am wondering as when I have called HP for service they can find my laptop. Very weird, but I am happy, Hopefully it will continue to work like this and I can begin to use this phone to its full potential.

yes samsung and google can both track your phone.
