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.
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.

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.

Your pc got a wireless dongle?
If so just turn your Nexus into a Hotspot, connected to the Network you want
Then connect your PC to your Nexus ??
Well, I didn't make it clear. I have a wifi version N7. All I want to do is share the wireless connection that the n7 is already on with my PC. So a wireless tether would not work.
You can try to spoof your N7's mac on your pc using Mac Makeup. Your pc needs a wireless adapter and spoofs your n7's mac, so it should connect to the mobile wireless network. You probably won't be able to have both devices on the wap concurrently.
I'm guessing the reason you're looking to doing this to bypass the proxy restriction your school placed on the resource. Keep that in mind in case you decide to download a ton of torrents and they trace the usage back to your N7's mac.

Yes, they would, but so what? Are they going to check all Asus devices? I'm sure there's plenty (unless you're in US, then Asus is very outstanding among all macbooks and iDevices). And you can't just assume he's going to download millions of illegal stuff. Maybe he wants to download Ubuntu via torrent
OP: I have not seen such a thing, there's normal tethering (3G to wifi hotspot), 3G-BT, 3G-USB, but I have never seen wifi-usb.
http://forum.xda-developers.com/showthread.php?t=1792245 check out this thread. With this adapter, BusyBox and some (more or less) basic knowlege of linux networking, I'm sure you could successfully share your wifi connection trough LAN cable, but I doubt it will ever work trough USB.
If you're running linux on your PC, then faking MAC address is so simple, that it's a better shot, if you're running windows, it's a bit trickier (but still doable).
Faking the MAC on a PC is simple too.
I'm not sure I'm even following this thread. Spoof your PC's MAC and jump on the mobile network. Done.
ALL devices have a MAC... so if they REQUIRE a specific MAC for access then they can trace everything you do online back to you. In that case I would be very cautious on what you do. They can also monitor bandwidth to your MAC (PC) and see you are pulling WAY to much bandwidth for a mobile device. If they don't care, then whatever but you may be getting a knock on your door.
You are basically circumventing their security policies and could put you in some trouble. So Clone your MAC address and keep it simple.
I've seen WiFi hotspot. Not sure if it was baked into sense though

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.
