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.

Any fix for the WIFI yet?

I've narrowed down the long list of problems that i had with my streak but one very annoying is still remaining.
Every few minutes i lose my internet connection and i have to disable WIFI and re-enable it in order to get it back to work. I even did a factory reset but same thing.
I have been reading about this from a lot of users. Has anyone figure out a way to fix this?

Never heard of it, are you sure you don't have a problem with conflicting ip addresses on your network?

No, I'm a network engineer.
If you do a search you will find a lot of posts about this. I surf the net just fine and all of the sudden no internet. Connection is there. The ip is correct, but no internet. Switch wifi on/off and it starts to work again. Very annoying. I suspect it has to do with the signal strength. Is there a fix to boost your wifi performance?

Nope, not had that one here too.
I've never had a problem maintaining a strong and stable WIFI connection with my Streak.

Same issue since I updated to official 2.2 (318). No problems with 1.6.

Can not explain, I just try to do so. dell is the time stability of the patch on the wifi.

I made some search. This problem happens only with 802.1x networks (WPA2 Enterprise). It's a problem of Froyo. The bugged file is /system/bin/wpa_supplicant. Some people reported that replacing this file with the one of Android 2.1 solve the problems.
I confirm that I have this problem only with the eduroam network at my university, which is a 802.1x network. No problem for open networks or at home (WPA2 Personnal).

I have had this issue since I got the Streak, even on 1.6. My home network is open - no problem with security issues, I live WAY in the boonies. For some reason, WiFi drops the connection and I get the little networks are available but not connected icon. I disable and re-enable WiFi and it connects back up by itself. Router is a Linksys and the channel is fixed not auto so there shouldn't be channel swapping. Sure is a PIA.

I have the exact same symptoms and I'm also using a Linksys router.

Glad this thread is up. I went as far as replacing my router with a Netgear WNDR3700. I had the problem BEFORE AND AFTER rooting and I've always been on 1.6.
So:
It's not a rooting problem
It's not a router problem
It's not a Froyo problem
Manufacture defect maybe?

router issue
I don't so much have a wi-fi issue as a couple of netgear routers causing a glitch.
I have mine locked down with mac addressing a wpa-psk (tkip) at home and on my wireless router in the shop at work. If I leave, I leave the wi-fi on my phone, I'll grab a free wifi signal around town, and sometimes when I get back to the work or home router, it won't connect until I reboot the router. Even after dumping the profile on the phone, connecting & entering the password again, it won't connect.
Goofy, isn't it?

I have this too on the Dell 2.2 official and on Steve's 1.5 and 1.5.1
I did not have this when I had one of the bug fixs for either UK 2.1 or 1.6. But it is a pain to have to reset the wifi all the time

[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.

Nexus 4 Wifi Issues - connects to router but no internet

Just want to know who else on XDA has a similar problem to me on the Nexus 4.
Recently moved country and took my Nexus 4 with me, got a data plan, no problems there. I was also was given the stock router for my ISP (Movistar) when taking out my broadband contract and my Nexus 4 is the only device that won't connect to wifi.
So here's what happens:
1) Network can be seen on the Android 4.2.2 Wifi Settings
2) I can connect, either by WPS or by entering the password, and Nexus 4 shows connected with indicator
3) Indicator instead of being the standard blue is grey, which seems to be no internet connection. I can get some access but at very, very slow speeds (about 9kbps)
The Nexus 4 is the only device in my house with the issue, no problems on PCs, iPads, etc.
Google have acknowledged this is a bug and there is a fix which involves root, but I don't want to root at the moment. Google also say it'll be fixed in the next update, but they've said that and we've seen 4.2.1 and 4.2.2 come out in the meantime.
Google Support also sent me a rubbish response to my questions about when it'll be fixed, telling me what Wifi is and how to turn it on and off..
So just want to know, are you having the similar issues with certain routers on 4.2.2 (stock)? I know I'm not the only one but I couldn't find any other threads.
Thanks!

I started having this same issue man! care to show me whats the root needing fix?

There are a lot of fixes in the Android Development Section.

Typically this can be a DNS problem if your router is not correctly set up to relay DNS requests (windows/OSX tends to be a lil smarter about it if it can't get the appropriate response from the router).
You could try to set a DNS yourself such as google's public ( 8.8.4.4 and 8.8.8.8 ) in the advanced properties when you long press the SSID you're connected to and see if that allows for internet access. If it does, then maybe you just need to log into your router and correct the DNS info.

Thanks for the responses guys

Tried that I'm afraid :/ No luck. According to Google it is the fact "they have no drivers for that router" considering they will probably have a generic driver for the average user to connect whatever the router.

Hi! It's an annoying issue, I'm currently tethering through Mac to get it to work. The root fix does work but drains battery life a lot more (instead of 0.5% per hour drain it's 5%). If you want to look I'll pass the link, but wouldn't recommend it.

See if you're able to do a traceroute from within android when connect to the router to see where it's failing.

And about changing routers, not possible at the moment. I've just moved abroad and have my old router somewhere too hard to find. Google are no help with this which is the problem, but if it persists in the next update I'll get a new router whatever the case.

The Nexus is a great phone, just a few odd issues which hopefully will be fixed.
This issue is persistent but dependant on the router. For example, my extender works perfectly whilst the main router doesn't - let me know what your router model is and I'll check to see if this will be common for your router

Hi!
Taken a quick look and doesn't seem to be any problems with your router. What you can do is to purchase the device and test to see it works on WiFi.
If it works, you're good to go!
If not, try some troubleshooting, so change channels, IP address, or even just a reset of the router could work.
Still not working? You can try what I did and buy an extender, but that'll set you back a bit of money.
You could wait until this is fixed, which we don't know when yet, or if you can't fix it you have a return period on which you should get a refund from Google.
Let me know what you decide to do, personally I'd try it out since it's likely to work, but I would return if not. But the Nexus 4 is a great overall device for the price.
Hope this helps!

OP, have you checked to see if this is an issue with the wifi access point of your router, or actually a routing issue?
To do this, set up ftp services on your computer or phone and login from the other device and copy a file from one to the other. If the bandwidth is good, your problem isn't with wifi but rather a routing issue that can likely be addressed in its settings.

I'm about certain this is to do with the router itself and not a routing issue, this is a common nexus4-my router problem and various other models.
I've adjusted every setting possible in the router settings to no avail, and all of my other devices which include other android devices work perfectly.
Sadly it seems to lie with a Qualcomm driver from what I've seen, and hopefully Google can fix in the next update

If you don't bother to check if you have good throughput over your LAN, you'll never know whether this is a wifi issue or a routing issue.
Drivers talk to hardware, i.e. Your wifi chip. That is all local, and has nothing to do with the routing (Internet) part of your router. Without knowing where the actual issue lies, you're just guessing if a new wifi driver will help.

Sorry, you seem to have misunderstood me and you're obviously making the assumption that I haven't already checked for routing issues.
As I said, my Nexus 4 is the only device in my house with this problem, all others work perfectly. From what I've gathered from these issues, it lies within the drivers of the phone.
WiFi works perfectly on every other router I've used with my N4, it's only my home router with the problem. It's a Movistar default router and other users have the same problems with this router (the brand is fairly unknown).
And I'm definitely not guessing that it's a driver issue - I've had this problem for over a month, I've tried everything I can: changing router settings, resetting, etc. So I doubt this is a routing issue but more an issue with the device, and from what I've read on other forums, this could be down to a Qualcomm driver issue.
Thanks for your help anyway!

I am not assuming anything. Simple troubleshooting 101. You're not getting a decent Internet connection. Could be wifi or router. I merely offered a simple method for determining which one.
Don't know who you spoke with at Google, but first couple of support levels don't have the stones to try and solve these things. And while I have no doubt other folks with the same setup are also experiencing this issue and that Google has recorded this info, that doesn't mean that a workaround is impossible.

G2 Verizon - Wifi Won't Connect

Has anyone had any issues connecting to Wifi networks on their G2s? I got the verizon version on Saturday and haven't been able to get the phone working on 2 different wifi networks. I can connect to the wifi network just fine, but I can't access the internet at all. I can confirm that other devices are able to connect no problem.
Curious if anyone has some thoughts on how to potentially fix this. If not, will be heading back to Verizon to get a new one. Thanks in advance for the help.

I have the AT&T G2 version , it will connect to any wireless router but the connection will last 5 seconds then no internet, this is totally unacceptable I upgraded from the G-Pro and may go back as that never had this issue, I did read LG had a similar problem with the Nexus 4 and Optimus G

Mine works fine. I have a VZW G2 and an ATT G2 connected on the same router. It connects to both G and N networks.

No issues with my Verizon G2.

Has anyone had any issues connecting to Wifi networks on their G2s? I got the verizon version on Saturday and haven't been able to get the phone working on 2 different wifi networks. I can connect to the wifi network just fine, but I can't access the internet at all. I can confirm that other devices are able to connect no problem.
Curious if anyone has some thoughts on how to potentially fix this. If not, will be heading back to Verizon to get a new one. Thanks in advance for the help.

Did you try rebooting your router? I see this at home with the families iOS devices a lot, especially after heavy data traffic. I'll turn off the router for a couple hours or overnight and the next day all is well. Router is open, no encryption.

I have the exact same problem. It will sometimes transfer some data using browsers, but nothing on facebook, pandora, or the play store it will say connection lost or not data connection.
My wife has the same phone and it works no problem and also the laptop. Must be a dud wifi radio or something like that. Mine is going back to the store tomorrow.

Are you trying to use adblock by any chance? I was and it was causing the same issue you have. I uninstalled it and changed my proxy settings back to none and wifi is working great now.

Just received my LG G2 White brand new from T-Mobile about 2 hours ago. After many attempts to troubleshoot the issue it all failed. The problem is Wifi will connect to router and even work but after 30 seconds the connection goes down. The actual Wifi signal shows connected but no internet it gets stock. We tried resetting the phone and toggling with different features but still it did the same thing. T-Mobile is the worst they were trying to have me ship the phone back and leave me phone less for days. I complained and they are sending another one overnight but have charged me for the phone on my account. Mind you I've had months of bad service, after all I think I got a defective phone. I've read some other people having the same issue with other carriers. If I get another one with the same issue I'm jumping boat. If anyone knows of a work around let me know. I tried 2 different routers same issues connects then it randomly disconnects and stops downloading or transferring data.
Reset Phone - didn't work
Turned off mobile data - didn't work
Turned off wifi sleep - didn't work

I'm on Verizon. I have trouble with initial connection to wi-fi. It says obtaining IP address for a very long time. Even if I have a very strong signal. It takes about five minutes. It eventually connects and works fine. Then next time I try to connect to that router it works fine. It's only the first time I try to connect to a new router.

I just got this phone over the weekend and I was also having trouble connecting to my home wifi.
It would stay connected for 30 seconds or a couple of minutes then disconnect however the entire time the status under the Wi-Fi settings page says Connected even though I couldn't access the internet or the admin page of the router. Frustrating. If I turned off the mobile data, the wifi, the phone, the router, or some other unknown combination of events it would then reconnect again for another 30 seconds to a couple of minutes.
I called Verizon, they told me to take the phone back since I was within my 14 days. I did this and was optimistic. Then the new phone immediately experienced the same issue.
I did some more research, changed my router from 20 mhz channel width to auto 20/40 mhz. Not sure why it was set to just 20. I thought that would fix it. Nope.
I tried to set my phone to use a static IP, that didn't work either.
Then last night I tried the WPS Push Button option instead of using a password. This method worked and my phone stayed connected. I haven't had a chance to repeat my steps to verify it works again but wondering how other people are connecting, password, wps push button, wps pin? WPS is not my preferred option due to the security risks but just trying to track down what works and what doesn't.
I am able to connect at work just fine using a password.

I'm having a similar problem - my work network has no problem connecting while my home network almost never works with this phone (~25% of the time, other devices have no problem). Occasionally, resetting the phone or just turning on-and-off WiFi fixes the problem, but more often I just give up and use 4G. Anyway, if anyone finds a solution, please post! This is such a standard feature that should really work out of the box.
In case it helps, my home network uses "WPA/WPA2 PSK" security and my work connects to "802.1x EAP" security - also I'm not adverse to changing the security options if it fixes the problem.
Thanks! Nick

After reading more on this, I've decided this issue is router related not phone related.
I discovered my router reached end of life in April of this year is no longer receiving firmware updates. Newer versions of my router have received multiple updates since then.
I will be buying a new router. I report back on if it works.

I really don't think it is "router related" as all my other devices work as expected with my router. A new router may fix the problem, but I'm pretty sure the phone's WiFi is buggy and not the router..

In my situation it really appears to be how my router is handling the connection when I connect with a password since I can connect with limited security.
Does your router have a firmware update available for it? If so, have you applied it?

Received my new to me router yesterday with updated firmware as of 10/7/13.
My phone was connected for a few hours last night and I have not had any problems today. I'll report back if I start experiencing any issues but getting rid of my old, end of life router and replacing it with a newer router worked for me.
I did not buy a brand new router either. I went with a cradlepoint mbr95 which has been on the market for awhile and has already had a few firmware updates.

Check you wireless security settings
Had a similar issue to this and it seemingly was resolved when I moved the wireless router security over from WPA/WPA2 personal to WPA2 personal only. The phone found the WAP and connected right away. I tried to reproduce the behavior but alas I have not been able to do so. Perhaps this will help others.

hi guys
i found the problem
it happens just when you disable auto update in "settings>general>about phone>update center>software update>check automatically"
