[Q] Captivate won't connect to WiFi anymore

So I just got my Captivate a few days ago and I love this thing. I rooted it briefly with OneClickRoot and removed some AT&T bloatware and the unrooted so that I wouldn't have any issues with the upcoming Froyo update.
I don't know if it's related, but now my phone refuses to connect to my home Wifi. It repeatedly says 'obtaining IP address' but then says 'connection unsuccessful' over and over again. It was connecting fine last night after I rooted/unrooted.
I have 'forgotten' the network and tried to reconnect without success. I have cycled the router and gotten it to connect very briefly but sure enough I'm not connected anymore. I'm currently on the wireless on my laptop and it's infuriating.
I've already been growing steadily unhappier with the GPS situation and now this is really putting a damper on my excitement over this phone.
Does anybody know what to do about this wireless?
And if all else fails, how do I get my phone to a point where I can return it for a new one that actually works?
Thanks for all your help.
Christine

Yes the phone can be returned to the stock state by using odin . Its very easy. You should first try to use a staic ip. Sometimes the problem is that the captivate chooses to use the same ip as some other electronic that's using that router.
Just go to wireless networks -> wifi -> (menu key) advanced and then plug in the static ip

I am somewhat familiar with static IP's but have never set one up before, certainly not on a phone. Do I need to specify a DNS, too, or just go in and specify a different one from my laptop?

I had that problem before. I just used Odin and flashed the stock firmware (jf6) back on again and it was fine.

Going back to jf6 makes me think there is something wrong with the wireless drivers. Anyone have more information?
Sine I started to flash new firmware I have seen my wifi refuse to connect until the 4th attempt.

On the laptop click start and click run. Type cmd then press enter. Type ipconfig and copy those numbers to your phone but make IP ADDRESS a different number.

Its probably your router
I had the same problem with my captivate. Everything else in the house would connect to the router but my phone wouldn't (even though we have 3 captivates in the house). Then the router started acting up badly so I replaced it with a nice cisco router and BEHOLD!!!! My captivate connects quickly now. no problems.
Cisco Linksys E1000 is the model router i got. Highly recommended.

Good point, power cycle the router and see if the phone can connect after that.

I had this problem with my Linksys router. I had to log into the admin settings and I increased the number of connections available and it connected immediately.

The app, FXR fixed my gf's phone with this problem.

[Q] Captivate Wifi Issue

Hi All,
I have a weird problem with my captivate of not connecting to my home network. Let me start by telling that I have searched the solutions and tried doing everything except full factory reset. I have rebooted the phone, done reset on my router (Wifi was working just fine earlier.. so I think settings was not an issue. But I still did it), I removed the file data/wifi/bcm_supp.conf and let it regenerate it. Captivate displays "Obtaining IP Address" and it just stays there. I also see that IP address is being assigned to captivate in my router
Captivate is rooted stock Froyo
Router security: WEP
form the Wifi list, I found one unsecured network and captivate connects to that router just fine (signals are very week though...). I tried removing the security on my router but it still stuck on "Obtaining IP address".
Can you please please help me?? As I mentioned earlier, It was working just fine and suddenly stopped working two days back.
These all app updates are eating away my limited data of 200M.
Thanks a millian.

What's your router model ?
What channel are you running on ?
Are others routers close to you running on the same channel ?
Have you tried another channel ?
Did you try WPA2 ?

Could be incompatibility with your router. That happened to me before with my old router. It didn't work with some cell phone wifi devices.
Sent using XDA App

Try using the app "FXR." I had the same issue a couple times and this app seemed to fix it. It took a few tries though. I think it might be a router problem. I use the Linksys wrt54g.

You could also try assigning a static IP address to your device on the router side, and then telling your phone to use that address. I've used that in the past to some success.
As a test, have you tried (temporarily) disabling the security on your router to see if it connects?

I have a similar problem since upgrading to the past 3 nightlies. My phone sees and connects to my home network and says it has strong signal, but when I try to access Market or Internet it says there's a network error and I can't get thru. My two computers (one hard wired and one wi-fi) don't seem to have any problem hooking in to the internet, just my SGS1

Does the 'FXR' app set up IP addresses?

The App didn't work for me. I tried that yesterday. I was reading the similar problems on some other site yesterday and I found the following that solved my issue. In case someone like me still struggling with the WiFi problem.
Delete file data/wifi/bcm_supp.conf
Delete file /data/misc/dhcp/dhcp_list
reboot the device and it will create these files again and you will have to enter your WiFi password again in order to connect.
I am really glad that my WiFi is working back again.

FYI, I'd change the WEP to WPA.

Where do you go to change that setting? I've been all thru the wi-fi settings and advanced settings, but didn't see anything that referred to WEP or WPA.
Just realized we're talking now about the router, not the phone, duh!

Yes, I certainly need to bump up the security settings on my router.

I used root explorer, but could not locate the files you mentioned. Directories were there just not files. I'm still exploring the router side. Thanks for the info tho.

Wifi problems with CM7 on Nook Color

I'm hoping somebody here can help me. I'm running cm7 on my nook color off of an sd card. For the most part, it's been great. I've been having problems recently connecting to my law school's wifi network.
I can see the network I my wifi settings -- it's listed as having 802.1x EAP authentication. I pull it up and select PEAP authentication (which is what my school says it uses) and then I enter my credentials. At this point, the Nook will connect to the network and get an IP. But that's it. No internet access. If I try to use the browser or dolphin to go to a page it'll just sort of hang there without moving.
Anyone have any ideas?

Try pinging your gateway and beyond, see if your packets are actually getting anywhere. I would think if you're getting an IP address you're okay, but who knows.
And are you sure you don't have a required proxy? There's nowhere to specify a proxy in Android, although I believe Opera it has settings for it.

So for our work Wi-Fi you have to sign in with what you already stated, but then after that I have to open up my web browser to sign in there as well.
Not sure if you have a similar situation or not.

I don't know about cm7 but cm9 does have a menu item to specify proxy setting in the advanced menu.

Depending on the type of device providing the wireless, I've also noticed that it helps to make sure your device name doesn't have a "-" in it.
It took me quite a while troubleshooting my sisters to figure that out. In her case it was a d-link wireless that was the issue.
There was a pretty good thread on this a while back that listed a bunch of troubleshooting steps.

[Q] HTC One Wifi connects, no internet, troubleshooting help

Hey guys. I am having a crazy problem. It all started about 4 weeks ago my phone started having authentication issues with my xfinity Router/Wifi unit (Arris TC862)... I figured at the time it was having problems with the encryption so I changed it from WPA/WPA2-PSK (AES/TKIP) to WPA2-PSK (TKIP).
That worked and it allowed to phone to connect to the wifi... But now I cannot contact the internet from the phone... I know it isn't the wifi module itself because it works fine on every other wifi that I try it on, subway and my work.
I am using ViperRom One so I have the terminal emulator... I am able to ping my default gateway of 192.168.1.1 which is the same router that I connect to via wifi, I am able to ping from my computer to my phone... So it appears that I am on the local LAN
I cannot ping google via name or by ip address so that rules out a DNS issue
I tried using a static ip address as well... 192.168.1.50 which I am sure my dhcp hasn't handed out
No other wireless device in the house has this problem
I guess what I am looking for is help if you know what the problem may be, but more specifically troubleshooting that I can do on the phone I am a network engineer but I know little about linux, and what the capabilities of the virtual terminal are... If I was at work I would just span (mirror) my cisco port and then hook up wireshark to see what is happening to the packets but I don't think this router is that sophisticated.
I would lean towards this being a comcast issue but the fact that this all started off with the authentication issue makes me think that it is a problem with the phone...
One thing of note, the router itself recognizes all my other devices as being android or a kindle but for my phone it says "UNKNOWN" which is basically just the common name, it recognizes the MAC and that is all that should matter... is there a way to change your hostname on the phone? I noticed there is no Ifconfig command in the terminal but I am not sure if that is where you would change that anyhow.

Well I figured out the problem... Stupid Xfinity
If anyone else gets this problem log in to your xfinity router; Under Parental Control - Turn off Managed Services - I do not know why this was blocking my phone but it definitely was
Apparently this blocks other devices too like blu ray players with internet ability

Thank you, thank you! Comcast idiots. Who would think that by default they wouldn't allow devices to connect? The weird thing is my HTC One worked for about three weeks on wifi and then magically didn't. Whatever, now fixed. thanks.

Anyone have a Chromecast with a Belkin N150?

I'm not seeing my Chromecast through my other devices with this new router. I eventually gave up and just plugged the old router in and gave the Chromecast it's own wireless network and we'll just use our phones on that one for now.
This setup does seem to have stopped the problem of the network being crippled by the CC, at least.

I had to upgrade the firmware and set IP on a DMZ address to get it to connect. Tried it on another N150 in another network and didn't have to do that process. Kind of baffled.
