Wifi connection issues - Captivate General

I have a problem connecting to wifi on my home router. Whenever I try to connect to it, it just says "Obtaining IP address from" then it would later go on to say "Disabled". I have entered the password correctly, made it forget the network and connect to it again, and have restarted both the phone and the router. That has not seemed to fix the problems. On other networks such as the free wifi at Border's or others it would connect just fine. I'm currently using Cognition v2.3b8.
Any suggestions? Thanks
Edit: Nevermind, I did a factory reset and it seems to be working now.

Have you tried android id changer? Not sure if the cog version you are on will let you write the new id or not, but worth a shot

Ok...I just tried that, it didn't seem to change anything. Thanks for the suggestion.

Seems to a 2.2 "intermittent" non-predictable issue. Faced this sometimes when on 2.2.

I have the problem but in reverse
I am using 2.3b8. I can hook to my home protected wifi but can't hook to any free open wifi connection

I am also facing the same problem as Slow_DC4...
Any help would be really appreciated ....
Looking forward to hear from you guys

Sarveshsj: I ended up reflashing the ROM and it fixed the problem, so you may want to try that.

wifi stopped working

somewhere along the lines of rooting or just playing around wifi stopped working. It stopped right after i added a hidden network and it connected. Now it just won't work. it tries to turn on and then just turns off. strange thing is that wireless tether works fine...
HELP~:?!
TIA
Same thing happened to me yesterday bro, tried everything to fix it and no luck, had to hard reset and then it's working again. Sucks I know, just make sure you back all your stuff up, I used "My Backup Pro" to backup my apps, contacts and data, search on the market.
Yesterday while trying to see if wifi tether or barnicle was working for the epic my wifi has seem to also stop working already tried a hard reset with no luck both apps have been uninstalled any suggestions?

What happened after you reset the phone? Would wifi turn on they say "unable to scan networks" then turn off? Or it wouldn't turn on period?
It says it is turning on and it also says its trying to optain an ip but then disconnects over and over. Its not my network since I am still able to connect with both my ipad and laptop.
Thanks in advance for any help!

Ok try this. I noticed when I turned wifi on after resetting the phone, it would scan networks, then totally stop working again so I had to hard reset again, after I hard reset right after I turned wifi on again I unchecked "notify me when an open network is available" and it's been working fine for me since. I honestly don't know why this happens but I haven't had problems after doing that, worth a shot for you.
Hey thanks for the help that seemed to work! Very strange

You're welcome. I'm glad it worked for you, but yeah it is very strange how it works fine after you disable "notify me when an open network is available". Samsung needs to sort this out, prolly a software problem
Also confirmed turning off network notification under wifi settings magically made wifi work again..... thanks man!!!

Wifi problem just reared its ugly head after 48 hours with official Froyo

I may have bragged too soon on good ol' official Froyo. I had a smooth install and the only problem I've noticed is the messed up Quick Office deal like most others. Today I just had another problem start.
I've been using my secured home wifi network fine, but for some reason the Captivate will no longer connect to it. I've tried doing a battery pull, turning the phone off and back on, and even completely removing the home network from the list and then putting it back in. I'm sure the password is correct. It just sits there, saying "Obtaining IP address". It retries several attempts, and eventually gives up and lists my home network in the list as "Disabled"
This is significant suckage!

I had similar problem try unplugging router and plugging back in
Bless your heart! That did it! I just read on the AT&T forums that someone else had the exact same problem and he did a factory reset of his phone which fixed it. I was hoping I wouldn't have to go there
I found an easy solution to the problem. Open Allshare, then you should be good to go.
After opening Allshare, hit connect.
Yes sometimes power cycling the router is all that is needed. I notice this with laptop sometimes too.

Yeah that was me...
I tried everything else before the factory reset, but the reset fixed it, now I've got wi-fi with no problems
If you do a factory reset, I realize you have to reinstall all your apps, but what about the ones I paid for? Will I have to purchase those again? I'm thinking of doing one just because I think it will smooth things out and get rid of a couple of weird quirks like the Quick Office icon problem.

anything you purchase with your google account is tied to your google account. you dont have to re-buy those...for any phone that you log into your google account.
Has anyone tried my fix? Sure beats having tofactory reset...I'm just sayin.

It works, but you have to do it every time, so it's more of a workaround than a fix.
I had an issue with connecting to one of my work wifi routers (would just sit there saying 'obtaining IP address' but never would connect) and could not fix it until I tried using "FXR WiFi Fix and rescue" app from the market. Free app, will erase ALL of your saved WiFi data so make sure you have your passwords for encrypted networks, but this fixed it with one click and a reboot. Seems to connect faster to the networks now as well. I had a similar problem after the previous update that went out OTA and had to reset the phone for that one.
I thought about trying this app, as my wifi issue returned today. I thought I had gotten rid of it by doing the factory reset, but alas it's back. I'm really contemplating a custom ROM more and more every day. I just don't know which one to go with that will provide everything I need. This app sure asks for a lot of permissions, so I'm sort of leary about istalling it.
Welp, I bit the bullet and tried the FXR app. No dice for me. I'm waiting for the wife to get done surfing so I can try a router power cycle. If that doesn't work, I'm looking at my second factory reset in less than a week. Froyo, you suck! I never had wifi issues until I upgraded to 2.2. What I can't understand is, why some of my issues are better, yet some are worse. Is it that difficult for these idiots to figure it out?
Just going to throw something out there, that I noticed yesterday. I'm on a custom ROM, but I noticed some pretty flaky results to my wifi, but only when I was using the modified TouchWiz launcher. The wifi had trouble connecting, and wouldn't sleep. The notification dropdown widget wouldn't control it. Then I switched to Go Launcher EX, and the behavior stopped.
Check another launcher, and see if that makes a difference. Sure, it's a longshot, but I'll be interested to see if the stock TW has the same issue as the modded version.
I was having the same wifi problem after updating firmware to official 2.2 kb1. I used fxr and now wifi connection works great.

So you can connect your phone to a wireless connection, it just doesn't download anything? In that case, have you checked the same wireless connection with another device?

Yes and Yes....im seriously stumped !
the only thing i can think is that theres some sort of wifi radio issue on my phone , but id have thought that would manifest by not connecting to the network rather than not pulling in data .
ive factory reset phone a couple of times and reset my router, no issues on other devices
think ill go back to the store for exchange as im not really prepared and shouldnt have to piss around with a brand new device
its a weird one
Have you tried changing the channel of your router? Try a lower number, like 11. Or temporarily removing any encryption and/or changing encryption type?
Did u try resetting your router? I had the same problem last night. Taught it was my phone. Ended up being my router. Go figure ;-p

Tried that....now at work and connects fine to the network, deffo must be an issue with my home network
Problem for me is that networks and the like aren't really my bag , ive had a look at the admin page on the router and can see its connected and theres nothing immediatly obvious that i could say "that looks suspect"
so im not sure what the answer is
all my other devices mac, pc ipod/phone and previous htc work well and have never had an issue
getting on my tits a little
ill have another fiddle later and see what i can do
cheers for the comments tho
otherwise, i do like the form factor of the phone and ill even give sense a good go befor i probably switch over to ADW or maybe launcherpro
Solved!
Set up static IP address on phone ..... Worked like a charm
I find the same, except I think it has to do with encryption. I have tried with wep and wpa and I get an IP address but cannot browse. On unsecured it works just fine.
Like you found a static IP works, but I think it is the static DNS that is actually the issue here.
This is a cumbersome workaround if you use wifi all over the place, so I downloaded Static Wifi which says it will store settings per connection.
The only issue with this is that I think the device has to be rooted for this to work
Have you tried using the opendns settings

wifi reconnect
Hi all
Perhaps we all have the same issue
I have the HTC Sensation with almost 2 weeks now and i am having one continuous issue.
I have wifi set up at home the phone connects ok,however i also have a TV/Video sender,when i need to use the TV/Video sender i have to turn off the wifi(not ideal).The problem occurs when i turn off the TV/Video sender and turn the wifi back on,the phone will connect with the modem but not to the internet,Facebook,Twitter,emails will not sync,while testing i have discovered that if i "kill" facebook and Twitter and restart the apps all is ok again i.e facebook,Twitter and emails all sync.
Does anybody have an idea what is causing this ?

I seem to have managed to resolve this by setting the security to wpa2 and i also altered the dhcp scope to force a new range of ip addtrsses higher up. Since I did that I've had no problems.

Authentication Error Occurred connecting to WIFI

This is a warning for Samsung devices! If you continue to get this error while trying to connect to your Wifi router, and it appears to not even attempt to actually connect to the router each time there is a simple solution. The error that will show is "Authentication Error Occurred" You can get closer to your router but it will not fix the problem, unless you actually have a different problem. This week I have had this occur on my Galaxy S Vibrant (Rooted with SlimBean ROM) and my Galaxy Note 10.1 (Stock latest version).
Solution to the problem (problem may be with installation of non-default launchers(For me it was Kid Mode a game for my kid))
Step 1 -- Intentionally put in the wrong password to access the router..
..it will of course fail...
Step 2 -- Put in the correct password. :fingers-crossed:
It will reconnect like new.:highfive:
This is what worked for me, and if you have the same problem (really no matter the Samsung device) it should work for you.
For whatever reason putting in the wrong password makes the device actually attempt to connect again. I had tried everything from placing the device on the router, resetting the router, restarting the devices, removing apps, factory resetting one device( which worked after two resets on the non-stock Vibrant), forgetting the network, turning off sleep mode in advanced wifi settings, adjusting all sorts of other settings.
Thought I would share my solution and I hope it helps more than just the Note 10.1 community if this occurs to others, which my google search results showed me it does and on many Samsung devices...which makes me sad, because I love my Samsungs.
Funny you should mention this.
I had the exact same error this morning on my 8020! I just reset the router and all good.

That is what my sister does on her S3 (resets router), but for some reason this works if you cannot reset the router... (its in use by others). Next time you have this problem (if you do again), let me know if this works for you?
Also I was thinking an app that I installed caused this problem, do you think you have anything on your 8020 that would cause this? (such as a childs game that blocks certain actions from occuring, or a firewall app)
You could also "Forget" the network then rescan... I've done this before too...

No idea. I havent installed anything different or done anything out of the ordinary. It hasnt happened since but it happened first thing when woke up.

are these the best solutions found? because i am having this problem, and none of these solutions have helped. and i know it isn't some program causing it, because I have wiped my i900 clean four or five times, and get it upon setup, before anything is even loaded on it yet, except the rom. so if anyone has anything else, please chime in.
I have this problem too and it's the craziest solution, but all I have to do is open up my laptop and open up a Web browser then magically my note 10.1 or my gs3 connects right back up.. So I don't know if it's some kind of interference or what? Rebooting my router also works. I haven't tried entering wrong password though but I will for sure try it next time since it means I won't have to pull out another device.

This issue is driving me insane! It did happen before and I've tried the password solution...it didn't work.
This happens every so often and it is quite annoying.
Has anyone found any fixes for this yet aside from the reset router or password solution?
was having same issue on my note2, both stock and roms, here is what I did and finally fixed it. Had to adjust the wireless settings on my router (dlink 645):
802.11 set mixed 802.11n and 802.11g
do not check "enable auto channel scan"
wireless channel: I set to 2.462 ch11
channel width: 20/40Mhz auto
security: wpa-personal
wpa mode: wpa2 only
cipher: tkip
hopefully this helps.

Here's my problem: (I get authentication error when trying to connect to wifi)
My Nexus 7 tablet and my friends laptop connect just fine but my Samsung Galaxy S3 won't connect
The SSID comes up and it says excellent or very good signal strength (in same room as router)
Previously, I had an S2 and it connected with no problem
Tried changing frequency band: 2.4 only, 5 only and auto (none work)
I can't play around with the router - it isn't mine and works fine for other devices.
My S3 works fine on my home wifi and several other places I have gone
Any ideas? Thanks
Assigning a static reserved IP for the device might help

First thing I always try is pulling the power cord for at least 30 seconds, reboot the router, and it usually works.

Thanks for suggestions. I'll try rebooting first, of course but I am not at my friend's house at the moment.
I don't know anything about assigning an IP address. If that has to be done to the router, I can't touch it.

[Solved] Router Reset Signal
My Samsung Galaxy 4 and my husbands Samsung Reverb were both throwing Authentication Errors every time we tried to connect using the wps pin, the wps button or the passcode. Nothing was working, to include trying incorrect password followed by correct password.
Hubby called Comcast and had a reset signal sent to the box. After the reset code was sent and the box cycled off and then on, Comcast verified the ip address once again and we pushed the WPS button for a fresh try.
WPS claimed to have failed on both phones but promptly connected. Problem appears to be solved for now so I don't care if the phones tell me that they're sucking toes! As long as they connect
I'll update if any further issues arise but for now I suggest calling your wifi provider and requesting that they flash the box (send a reset signal).
Good Luck!

Had a harrrowing experience solving this.
Was trying to connect wifi to note3 but it was seemingly stubborn in giving authentication error.
Had tried resetting the device, even changed router settings and yet it does not budge.
At last it dawned on me to stumble on access control list. In router settings there is option for setting access control for the devices used. Once the devices are added and the access control is turned on, it does not allow any other device to connect even if the credentials are correct.
So, once I have unchecked the access control list in router settings, it connected instantly.
I must have realized the same. Being oblivious of this fact costed a day.
Hope this helps.
Thanks,
connecting to wi fi with tablet
We had a tablet that previously logged onto our Wifi but after taking it to school and returning home it wouldn't reconnect at home and asked for the password. I think we may have put the wrong password in too many times then even when we use the correct one it wouldn't connect.On the advice of our data provider we changed the name of our Wi Fi router in its set up and suddenly we could connect again when entering the password correctly. Worth a go if you have put the wrong password in too many times or your tablet just won't reconnect or even forget the connection.
I got this prob with Note 10.1 today and then after connection, dropping wifi and reconnect every 10 mins or so.

Can you connect to any other wifi network?
If yes, then there is a problem with your home wifi router.
If no, then there is a problem with your phone.
EDIT: After a bit of searching, i came up with this,
Your wireless network may need to have your devices mac address before it can recognize and grant wifi access to that device.It turns out you need to add the mac address to your router so that it can let the device associated with the mac address connect to the network. If you don't know how to do this, or can't find another solution, call your network provider for assistance. They should be able to help you out. I cannot tell you how to fix your problem because I don't know (and don't want to know lol) your router address / IP address and password.
