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.

Thanks for that, i figured the menu was built in somewhere just never found it.

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.

Wifi issues - most likely not the phones fault

I am having intermittent Wifi on my phone; but at work only. Everywhere works perfect without dropping the signal, but at work the signal drops once every 10 minutes and I have to toggle Wifi to get it back. It doesnt matter of I sit still or have the screen on or off, it always happens.
One thing to point out is that on my iphone I used to use WPA enterprise as security, but on this phone WPA doesn't work, only EAP security. Its the kind if network where you have to login with a username and pass.
Anyone else experiencing this?

Ok I've figured out where my wifi disconnects are coming from at work. It IS an Android issue so I'll keep posting it here. The problem is that my work needs to use a certificate from entrust.net in order for the wifi to connect and stay connected. I can connect to the network and have full internet access, but after a few minutes its as if the network checks my phone for the certificate, and when it can't find it, throws me offline. Now here's the annoying part. I went to entrust.net to look for the certificate I would need to put on my phone, and found that they offer 4 different certificates. I then looked on the phone at the bottom of settings>location & security and found, "manage trusted certificates". There was a big list of certifcates preloaded on the phone. And guess what? All 4 entrust certificates came pre-loaded on the Atrix. So the problem is not that the certificate is not on my phone, the problem is that I can not associate the certificate to my wifi profile for work.
There are even 2 options under the manage wifi connection that reference certifcates, but when I click them to try and load a certificate, it won't allow me to select anything. I'll post a screen shot of that at the end of this post. If it means anything, the iPhone 4 will auto-pull that certificate when trying to connect to my network here at work. As soon as you connect it will ask to accept the certificate. My work uses WPA Enterprise.
Screenshot: Oh yea.... I forgot, I can't find a single app that will screenshot on the Atrix. What a cool feature we are missing out on. Actually a very needed feature in my opinion.
Please help me or point me in the direction where I can find help. WPA enterprise is pretty common in the business world so someone has already come across this, I am sure.
Sent from my Atrix using XDA App

Android does not have native support for LEAP either. I went through a similar mess as you trying to get my Atrix to connect at work. I had to download the wifi advanced app in order to get a connection.
I'm sure you're already searching "WPA Enterprise Android". It may be worthwhile to see if there's a wifi app out there that could fix your problem.

I have that app and can add extra options yes, it still doesn't allow me to deal with the certificate problem though

Odd place to ask this, but I would say try out Tor Browser. Also try Firefox portable (assuming you can stick a flash drive in the computer), there seems to be something about it, can't explain it, my tethering isn't blocked on it, but is on IE, and at my work websense doesn't seem to be able to block me.
Oh, if you get fired for non-work related web-browsing, I claim no responsibility.

well that depends, if your admin is worth his pennies then no, it wont help at all.
setup a white list on the physical router to the outside world and your snookered.
If they have just blocked access via the DNS server and its simply unable to resolve names then you could try bring up the command prompt and ping a website via its IP address type
ping 208.67.222.222
if that works then change your DNS server to that IP address, its an OpenDNS server, very good as it happens, if it doesn't then your screwed unless they are operating a black list, but that's just stupid as you could simply find a website not black listed or make your own that uses a frame to redirect to a site of your choosing.
NB, they might have locked that ip address too so try some others, less obvious ones
the trick is finding out how they have blocked you first, then you can see if there is a way, but white lists are a real pain in the arse, they might even just run a proxy server and have cached sites on that, if they are running a proxy server you could try and delete those settings, just make sure you write all this down or your admin will likely get a bit pissed off at you...
and a final point to remember, your often blocked for a good reason and that reason is usually in your contract of employment, you connecting to sites your not supposed to will stick out like a sore thumb on the router logs as well so as ^ said, if you get fired its not our fault

I used to work at a hospital that started blocking us from alot of sites. We eventually figured out they were using Symantec to do it so everyday we would uninstall it. Some days it would last all day, others it would last 10 minutes but we could usually wait and uninstall it again to regain access. We used xp on all the computers and we were assigned to different pods almost daily so we never were caught; not that they couldn't figure it out if they tried. If they are using Symantec then you may be able to uninstall it, otherwise you may be screwed.
I am still a RN and goto school with my patient. We are blocked on laptops from certain sites but I am not blocked on my phone. I can tether my phone to my laptop and it allows me access for some reason. I'm unsure if this is an option but figured I would throw it out there.

Symantec .....XP
**shudders**
is it at all possible that even though you have your phone connected via wifi that it still has a GPRS or HSPA signal? if so then its probably bulking at the lack of access on the wifi then switches to GPRS.

Ya I agree about the xp and Symantec but with 2000+ terminals, I'm sure it was the simpliest solution.
When I'm tethering my laptop via phone at the school, we don't have cell coverage in the majority of the rooms, which is why they give us a basic internet access so I don't believe I'm pulling in my mobile data, if I'm understanding your question correctly.
I'm back there on Friday and will see what's being blocked before tethering and then see what my data is looking like afterwards. I was "assuming " they were running different security for the mobile devices, allowing the loophole, but could be wrong.

Help Connecting android to wep secured router

No one at work with an android phone/tablet can connect to the WiFi. IPhone/pad Windows p8 and laptops. Connect fine. It gets stuck at authentication error or can't authenticate at least on my phones/tablets. I don't know if there is an firewall issue but I find it hard to believe as other devices can. Is it an android issue? We have like 10 or so access points or extenders all under the same name. I don't know if maybe I need to find the main router and try connecting to that... any ideas?
Sent from my SCH-I605 using Tapatalk 2

Are you sure it's WEP? It sounds like you're using a flavor of 802.1x WPA like EAP-FAST which isn't really supported on Androids.

It shows up as WEP secured.
From what I've gathered. Some android phones used to work but there was a lot of people that couldn't connect. So they called our IT guy and he called our network guy and they got it opened up so everyone was able to connect. Then a short time later android stopped connecting

Long time ago but still an issue. Anyone know the issue?
Sent from my SCH-I545 using Tapatalk 2

First of all, WEP is highly insecure, but I don't know why you would have problems. I would upgrade the security to WPA/WPA2 to prevent people from "stealing" your internet.
Sent from my LePanII using xda app-developers app

Usually it's an issue with the router/AP, not the phone. No idea why either.

Normally the security protocol is WEP ,its ok..the problem is not with your phone maybe they adopted for MAC filtering..you should try to check with the network admin..or try connecting a laptop and see if it works with the same protocol..or try to check with the network admin to move on to wpa or wpa2..maybe things can sort out

VPN works fine in Wi-Fi but not with 3G

I'm hopeless here. I have a paid VPN service, and it works perfectly with my PC, with my mobile on Wi-Fi and with my friend's mobile also on 3G, but not on mine. For sure there's something wrong with my device. I tried hard reset, different ROMS and all different servers and settings.
It does connect to the VPN and it keeps up the connection, but internet just doesn't work. Anyone have any idea why this is happening? I tried to search other threads about this, but no success.

vpn thrue 3g and mobile connection
hi
reason, routing.
1. you have to setup your vpn connection to route any data between your vnp-connection.
or
2. you use another apn who route unsecured and secured data to different routes.
(secured data = VPN, unscured Data => www)
Check the isp apn if it use a stateful paket inspection firewall. this apn can ussually only route secured data (vpn).
Its no bug its a feature to solve some problems like too much connections, timeouts, reduction of hacker attack surface, and more..
you can find this information in the special vpn-whitepaper from your isp.
i hope this helps you.

How does the go to my p.c. app work?Is it pretty good app. Thanks

When you set up the VPN on your phone, make sure you fill out the forwarding fields as 0.0.0.0/0.0.0.0 otherwise no traffic will be forwarded through it. Testing on wifi from the same location as the host is a miserable way to test VPN as it tells you nothing. Turn off the wifi, and always test on your mobile data. There ARE carriers out there that WILL filter out VPN connections for normal user accounts and require you sign up under a business-class account to use such connectivity, this is because they want more money from you, and to not give you an easy way to get around their tethering detection. Plus in some countries, you're not allowed to possess the capability to encrypt and secure your own data/traffic and the means of encryption are banned (and therefore filtered "on-the-wire").

Use VPN Service that has open port. Like http://xtreamvpnworld.blogspot.com ive been using it for more than a year. I got no problem.

That's seems odd. Anyway I haven't tried built in vpn, how about openvpn? Have you tried it? I think built in vpn doesn't support voips like viber etc. Or maybe your vpn provider does not. I really don't know. Because I tried using droid and xtream vpn it works on every chatting platforms.
