Wifi Problems

Well I've had my Captivate for 3 months, and up until now it's been smooth sailing. Two days ago I came home and my power was off, and when it came back on I tried connecting to my router like usual, but now it won't connect. On the "wifi settings" menu it just says "obtaining ip address from..." for a few seconds then it says "disconnected" and goes back into "scanning..." mode. Also, under the "wifi networks" section it shows my network as "Disabled, secured with WPA/WPA2 PSK". (I am using a Linksys WRT54G with WPA2 security f.y.i.)
I've tried "forgetting" the network, I've deleted the whole file that remembers your networks, I've tried connecting via WPS button, I've double checked my password, I've power cycled my router, I've reset my router back to default and re-configured it...still nothing. It connects to the wifi on campus with no problems (in 4 different buildings), so obviously there is something wrong with my router setup.
If anyone has any advice on how to resolve this problem, it would be much appreciated!
**Also, I forgot to mention I am running Cognition v2.2 Beta 6

Bump for hope

Does anything else connect to your router

Happened to me a few times. Only way I could get out of this was to restore to a previous backup, or install fresh again. By the way, I experienced this problem only on 2.2. Never happened on 2.1.

Unfortunately I don't have anything else with wireless to test.

Elaborating on the issue
I've encounter exactly the same problem described here.
Samsung Galaxy S I9000. Froyo (official version). Not rooted.
Now it is the first time it has happened, and still I have not found a solution (restarted the router, restarted the phone and made more tests).
Before the upgrade to Froyo it has never happened. After the upgrade it worked ok for several days untill now.
Several other deviced at home are well connected to the router.

Its just s stupid suggestion maybe... but have you tried to change channels with your router?
Sometimes is just a stupid channel issue....

I found out the answer to this problem. I had to connect using static addressing. It seems at some point, the captivate 2.2 roms get confused for some of us and it starts trying to assign an IP address already used.
In my case, I tried everything... rebooting phone, router, ect.
Laptop connects fine, Wii connects fine...
But, I decided to connect via static addressing... BAM connected perfectly and instantly.
Connecting to other DHCP networks seems to be hit and miss as well.
So, I'd suggest reflashing might be the overall fix. But if you're like me and cannot reflash right away, try static addressing till you can get around to it.

Not stupid at all, but unfortunately yes, I tried a couple different channels and still nothing.

Awesome! This sounds like a promising solution, thanks. Yeah I need to reflash soon anyway seeing as how Cognition is up to 2.4.x already...
Probably won't be tonight, but I will do this soon and let you know my results.

Alright, I have typed just about every keyword into google relating to setting up my router/phone to use a static IP and for some amazing reason there are ZERO results that have any information whatsoever about setting up a static ip on a phone. This is really frustrating, so if anyone would be kind enough to explain how to do this or link me somewhere that does, that would be awesome

go to your wi-fi settings and click the menu button.
it should pop with a "scan" and "advance"
click on advance and scroll down to "use static ip address"
then i guess you have to put in your network details, not sure on the details there cause i have done it but experiencing same problem with my galaxy s
power went out and now can't connect to my network
Edit : Possible fix
I just managed to connect to my network.
I put the device in flight mode and restarted my modem at the same time
put it out flight mode and pluged in the modem again and now works.
Hopefully that works for you to guys.

Yea, works perfectly. I have my laptop connected to it right now. I usually have to reset the phone to get wifi again.
edit: I set it to static ip, but then i got the same problem. Except now google search engine works No webpage opens, youtube app didnt work either.. only the search engine worked.

Well my phone must be in a good mood today because it just decided to start working again all on its own! I don't know what caused it...I have actually had both my phone and computer constantly on since this started happening. So for now I'm keeping my fingers crossed and hoping it doesn't mess up again.

This is probably just for me, but this isn't a viable solution.
The ONLY router I seem to have this issue with is the one that Verizon gives all it's FiOs customers. It's the Actiontec M1424WR Router/Modem. I know my WEP key is correct because it works just fine on all the laptops and other phones (a Palm Pre and another Captivate on 2.1). It tries to obtain an IP address for about 5 minutes and then just sits and says disabled. Does anyone know if there's a way to dump the DNS cache or whatever like you can on Windows?

Add me to the list of ones having this problem...guess I'll try to reflash everything in a bit to see if that fixes the problem.

Just an update I backed up everything using Tibu and then just restored it and my WiFi problem went away.

Mine is stock and just started having this problem....will connect to other wireless routers except mine, really pissing me off!
I've tried many times having the the phone "forget" me, then put in my password(which is correct)...same thing over and over.

Same problem here
I have a galaxy s and the recent update to froyo brought me the same problem already described here.
And the "funny" thing is that my router doesn't have an Static IP option, it's a simpler router from the cable provider.
So i'm trying also to find a solution to this. Two days ago i changed the wifi channel and it worked. But today i have again the same problem and changing the channel don't work anymore.
Each time i find a possible solution, it only works one time.
This is really annoying me. This must be a froyo bug, 2.1 never gave me this problem

It must be a froyo beta bug. Remember we don't have a final version of this firmware for the Galaxy S family.

my internet is broken...q

so i was trying to get vnc going on my pc/nook and ended up killing my internet capability on the nook.
im connected, and have reconnected, to my wifi but it has not solved the issue.
anytime i try and load any internet using app, it just closes. xda app says "missing internet permission"
wtf mate?

Happened to me once...
Try deleting the saved password for the wireless connection and then unplugging the router, then plug the router back in and reconnect...
Worked for me.
P.s. you can delete the save password by going to:
Settings>wireless and then by tapping your wireless connection and selecting "forget"

WIFI Question

I have the Nook Color and software version 1.1.0, no rooting or anything....for some reason when I put on my WMWifirouter, my nook doesn't see the network..though my laptop does. Anyone have any idea why this might be?

Not familiar with that application, but does it run in ad-hoc mode? That would explain why you don't see it. I believe there are threads around which explain how to get your nook color to see ad-hoc networks.

yes it does run in ad-hoc...okay thanks that is a start..

I know that I can run the normal WiFi Tether app just fine. The only thing I have to do is change the channel of the network every time I try to connect to it. If I don't, the NC is stuck at "Obtaining IP Address..."

This is after you root it and enable it to work with ad hoc? The reason I wanted to do this is so I can use my phone as a wireless hotspot, because I don't have wireless access at work.

I'm sorry, I just realized you didn't have an Android phone... =/ In that app, is there anyway you can change the frequency channel? I remember the first few times I tried to connect the NC to my Droid Incredible, the network didn't show up or I couldn't connect to it. Once I changed the channel, it was able to connect.

that is a good question, I will have to see, I only recently got the program, so I will mess with the settings and see what happens.

do you happen to know which channel you changed to?

If I remember correctly, I didn't have success on channels 1 - 3 to start off. I usually pick any channel from 4-11.

[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.

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.

Rooted Nook, no internet

I've rooted my NC using verygreens way and I am not able to connect to the internet. I've turned on wi-fi but just not getting this. Help!

Try forgetting all remembered networks and letting it rediscover them.

Thanks, but that did not work. It will connect for a brief moment but won't hold the connection.

Ok, so I took the Nook to the mall with me and it connects fine. My problem seems to be when I'm home. It keeps searching for connection. What's going on. Is it my router? When using it without the SD card, my connection is fine.

Did you enter wifi passcode correctly?

Most likely the problem is with your version of CM7. From you other posting, you have dual boot. When you remove the SD card, you are boot BN stock - and that works. When you have the SD card in you are booting CM7 - so it is a setting in CM7. Try setting your router at home to 802.11g only and see if that helps.
