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.
Hi All,
i switch wi-fi on and the phone find the access point and connect to it. But it doesn't navigate to the net or market or anything else. Otherwise if I use the 3G it works perfectly. Just try to initialize it twice. Same problem.
Some suggestions?

Hmmm, could be a multitude of different things. A few questions:
1 Are you rooted?
2 What security settings do you have on your router?
3 Have you ever been able to connect to the web thru your router?
Answer them and I will try to help.

Hi MrZak,
1) phone is not rooted, unboxed 16 hours ago;
3) I always use the router with a mac and a pc on windows xp
2) I do have some doubt about the router (it's a cisco linksys). Even iPad has several connection problem BUT, i tried a different router last night (3Com) and it doesn't work too while iPad works fine.
Firstly, update the phone from:
Settings / About Phone / System Software Updates
If that doesn't help, try a factory reset.
Also, when you go into your router settings is the phone showing up under devices?

It could be a simple IP problem. Try with static address and see if you can access your LAN and internet.

It doesn't work BUT... I tried with the 3com router this morning doing a simple "restore default" in browser web. It worked. I tried to do the same at home with the Cisco Linksys router and... it doesn't work. Could it be the router?

Can you please try to put a static address and ping it from the local network. Preferably ping it from a computer that is connected to the router via cable rather than wireless. If you can ping it, the problem is definately with the router. Also please check if you have MAC security enabled on the router. If you do, you'll have to add the DHD's MAC address to the table.
EDIT: Or you can try to install ping from the market and see if you can ping your router.

I installed the pinger from the market. Anything to ping. It states "WIFI network may block outgoing ping request". Simply WiFi on the phone doesn't work . Any suggestion?

Try connecting through an unsecured network like some coffee's hotspot and if it still doesn't work, it's faulty. Until then, it's more likely to be your network setup.
Edit: just read your previous posts again. You say that it worked with the 3Com router, so it's not a problem with the phone. Check the security settings on the Cisco router. Check if it's using AAA/RADIUS server, MAC table, etc. The fact that it connects but no traffic passes through is symptomatic to a security problem, not a hardware one.

My WiFi was working fine on my Xoom, and now it gets stuck while "obtaining IP address." It says for a split second "remembered" as if it was connected and starts the ongoing circular process of "obtaining IP address" all over again. I saw that galaxy tab users had this same problem and found a resolution by connecting "static" instead of "DHCP." I didn't try that as I honestly don't know how. What I do know is that there are a few devices like my OG droid, my laptop, my mothers' laptop, my xbox 360 that are connected to the same WiFi network. This randomly happened, when I decided to disconnect from WiFi to run a speed test on 3G and I was unable to connect to WiFi ever since. I tried unplugging/plugging the routers, turning the Xoom off and on, and even went so far as to doing a factory reset on the Xoom and I still can't connect. 3G works fine, but I have a 1GB cap and I would rather only use that while I'm on the go, and obviously WiFi is definitely faster. If I can't resolve this, I still have enough time to return this thing. Call me a newb, but I need a little help!
I know you said you did a factory reset, but google stores wifi passwords in the cloud now. Try making the xoom forget the network you're trying to connect to.
My only other thought is that you need to go into your router's configuration and remove the xoom as a remembered device.

How do I get the xoom to forget the network? How do I remove the xoom as a remembered device? Sorry but I really don't know how to do that..
EDIT: I went into settings>privacy>backup and restore> and unchecked "back up application data, Wi-Fi passwords, and other settings to googles servers and was still unable to connect.
I think if you long press on the wifi network it will give you the option to forget it.
As for the router, do you remember setting it up? The settings pages where you set the wifi name and password and such.. it should have a section where it tells you which devices are connected.
I have pressed "forget network" on the xoom several times when trying to connect. As for the router, do I remember setting it up? No, as a matter of fact I didn't set it up. Could I configure this thing from my laptop?

Of course, anything that's connected to the router should let you configure it. It's too complex to explain here, but you need to enter the router through it's IP address and find the configuration.
Find the manual for the router you have and go from there.
I'll try to look into that, any idea as to wtf happened? This is beyond an inconvenience..
I'm having much the same problem. After entering the passphrase it says 'obtaining ip address from....' and thats all. It never connects??? I have tried 'forget' several times and no luck.
I have been able to connect to unsecured wifi with no problems.
Use the free app "wifi static". Config to assign you a static IP on that network only and dhcp on others. Its something within android as I have the same issue in my phone with a few networks but not most.

OK, tried it. NO GO! After entering the passphrase it STILL says 'obtaining ip address from....' I may be doing something wrong with the app since it comes with absolutely NO directions. If this is going to be an issue average folks will take it back!
Have any of you with this issue verified that the DHCP scope on the wireless network is not full or that DHCP is even allowed? The fact it works one place but not another tells me the issue may be with the network and not the device.

I also had this issue, I ended up fixing it by upgrading my router BIOS. the version that was on there was dated 2004 (yikes), and though the most current update was only 2006, it seems to have fixed the problem.
That or the reboot after the update as previous poster said and the update didn't really have anything to do with it, but either way it got fixed.
Help to solve it please..when i try to coonect to the internet via wifi without pass there is no problem...but when i try to connect to a wifi with pass, i enter the password,and the phone shows that it is connected.but i cant open the web pages.it isnt working
Did you add your wifi mac address to router to allow filtering? That should solve your problem.
Sent from my GT-I9003 using XDA Premium App
Can u say step by step how to add please?
Well it depends on your router. I cannot exactly tell you as your router software will be different than mine. Just enter into router settings, hope you will know how to? Look for wifi section, and mac filter, you will have to add your phones wifi mac address, its unique to phone. Menu> status> about phone> wifi. Tour wifi should be on. Then try rebooting the modem. Just try to use use wep encryption using 64 bit key, if it works try higher encryption levels.

Hi there!
Im on Froyobread v023b by dx. The thing is that the wifi connection (to wireless routers) isnt working quite well. It works okay at my home, but when i want to connect on a caffe wifi area, or at my school, i cant.
At my school, under the name of the connection it says "protected with WPA/WPA2 PSK" I dont know if it changes anything, but well.
Its always the same, i connect to the router, put the password, wait, and it keeps saying disconnected, or out of range even when i am on the range of the router.
Any help?
Goodbye!
I'm having the same problem with gingerDX. I use WEP security in my house and it works ok. But can't connect to any other wifi protected with WPA/WPA2 PSK =/
Try a full wipe

I already did a full wipe but it didnt change. It happened the same when i was with gingerdx.
And it seems to be the connections with WPA/WPA2 PSK

It's a problem with configuration and compatibility. Different routers/ap's use different configurations, and configurations can have different settings.
I can only connect to my router with modded roms if i disable N draft on it or it gets on a "connecting loop". Does it mean the phone cannot connect with N routers? No.. I have no probs with my girlfriend router and it has N enabled.
You seem to have problems using WPA.. I use it also use WPA and have no probs.
The modded wifi libs must have an incompatibility with some settings.
Some routers allow you to tweak them alot, maybe changing some values can do the trick, or even changing the WPA encryption type..

DX already tried different libs but they all work incorrectly in some cases
My university uses 802.1x EAP with mschapv2 authentication. I don't have a problem if I go back to the stock eclair rom on my x8, but with froyobread and ginger dx, i get occasional connections, followed by drops, and then the scanning-connecting-disconnecting problem. Usually, I have to forget and re-enter the network details to connect. With Ginger DX v12, I can't connect at all.
i updated to DX v12 and connected today to my univ. wifi with no problem. i wasn't able to connect with the earlier version.

Are there any custom roms for the x8 that work well in general and also don't have wifi problems?
I think "protected with WPA/WPA2 PSK"is the problem, my phone can't connect to this kind of net work, WEP and OPEND is Ok.
