[Q] Wifi - Obtaining IP - Galaxy S I9000 Q&A, Help & Troubleshooting

I am several hours around my phone and still wasn't able to figure out what's wrong with the wifi.
So, for the start, i was using ICS 4.0.3 for about 2 months or something, everything was fine. Today i decided to install a custom JW5 to give it a try, since it has some "secundary" features that i would like to use. The problem came after this. At first, i installed everything just fine, on first boot i can connect my wifi to my router, but as i start to use the internet (browser or google play) it just disconnects after 5 seconds or so. After that, the wifi stay on a loop scan-obtain ip-disconnect. If i just switch off and on, it won't pass the obtain ip. For it connects, i must reboot the phone.
I thought it was a rom problem, so, i started trying another roms: jw5, jw4, jw1, all custom and all stock, none worked. I tried to use several modems, like jw4, jvq, jvu and so the same with kernels: semaphore kernel, stock kernel, everything. Nothing worked.
Although, i tried the old JVQ rom and wifi worked just fine. I didn't tried ICS again because i don't want to go back to it and neither i want to use an old rom like JVQ, so, is there any way to fix this?
Rebooting the modem and router didn't work aswell and i have 2 other computers using it just fine (just like the galaxy worked until today). If someone could help me, i appreciate, i'm really tired wasting time with this.
EDIT: i forgot to mention, i tried with static ip, didn't work either.
EDIT2: i already tried delete the file from /data/misc/dhcp too.

[Q] Wifi broken, need help please

After a few days running Dlev's 4.2 ROM, my wifi stopped working suddenly. When I try to turn it on it says error or unable to start wifi. I've exhausted several initial options I began walking myself back through various ROM's back to the original 2.1 stock ROM. Without success I even performed a master clear and several reflashes of the orininal stock ROM, nothing is working. I tried FXR Wifi fix and rescue. Does anybody have any ideas on what I should do?
Thanks,

Kernel?
What kernel were you running with the custom ROM? Talon's being updated really frequently, so if it's Talon, you might try the latest version of that (0.4.4.22, as of this writing)

Did you try rebooting your router or device that gives you wireless signal? also see if other devices can connect.
It was Talon 0.4.4, but I've gone all the way back to stock ROM/kernel etc and that makes me think that this is a HW malfunction.
AT&T had me reboot the router too, my laptops are able to connect just fine. It's not really a connection problem either, Wifi will not turn on at all.
I called Samsung and they want me to ship them the phone, still debating that one since I will have to go without a phone.

[Q] Wifi Can't Connect To Networks It Can See

Hey folks. I'm running on a stock UXKH2, flashed through Odin. I'm not rooted because it seemed like a lot of doing, but everything else is working perfectly except for my wifi.
I'm able to see networks but I can't connect to them. I've tried a few open networks as well as a few secured ones, including my home network. All the security was checked and double checked and I still can't seem to get a lock. I'm wondering if I should be flashing a custom modem?
Quite interesting post actually..I would love to see how people response to this..
no such thing as a custom modem, they're all stock modems just different releases...
have you tried forgetting networks turning off wifi, clearing cache and dalvik cache and trying to connect again?
you may have to reflash, i posted a zip in the kj2 thread for rooting, you just flash boog's kernel with odin and then flash that zip i posted in cwm. not all that difficult. so that you can backup your stuff before you reflash and restore after..
I know some of these older GB ROMs had wifi issues. I'm more familiar with the US distros but I'm sure the same was /is true for Rogers' too.
I have this issue all the time. One day the phone connects to the access point with no problems. The next day it refuses to connect and "disables" the connection. The only thing that seems to fix it is reflashing. And that's such a pain!

[Q] Need help connecting to data!

Im new to flashing roms, so bare with me. I flashed my first rom last week, using Andromeda3 and Ursa Minor #2 kernel, everything worked great except, i couldnt connect to 3G/H, even though it showed up on notification bar, tried looking for answers, i ended up flashing different modems to no avail. So, i flashed back to stock eclair, used kies mini to upgrade to Froyo 2.2 UCKB1, Data worked. I then flashed UCKB2 rom, data didnt worked) i tried wiping cache and all that, still no data connection, btw, wfi worked. So i flashed back to UCKB1, again, everything worked perfectly. The other day, i flashed Fusion XI and GB bootloaders, i must say i like this rom very much, but again still couldnt connect to 3G/H, everything else worked, although i havent tested the GPS yet, i am getting amazing DL/UL speeds through wifi. Anyway, i searched XDA for any answers i could find and pretty much tried them all, seems like only KB1 3G will work, but any custom rom out there, data hasnt worked even though i see it in notification area, i'd use market and browser, but would say could not connect. Am i doing something wrong/ missing a step?? I really like Fusion XI and dont want to flash back to stock. Any help would be appreciated.
Didnt know where else to post this, seems like other people dont have the data connection issue :/
That's weird.
Try flashing the kb1 modem on fusion.
I did try flashing the KB1 modem, but that too, didnt work. it only works if i go back to stock KB1 for some reason.
where do you live? what Carrier are you with?
have you checked your APN settings?
fill in your location and carrier/ device info in your signature/ xda user information.
I Live in Southeastern Pennsylvania. And currently have AT&T as my carrier. I tried APN settings, but not sure what to set it too, i have used APN Manager from the Market.
Try resetting ur apn settings to default. Then reboot.

how do u reset apn settings?
Settings, wireless and networks, mobile networks, access point names. Now hit the menu key and reset default apn well be on the bottom left...
Ok, tried that, still a no go connecting to data. I just flashed stock 2.1 then 2.2 update through Kies mini, i no longer have data connection even on official stock roms could this be a hardware issue??? gps sucks. ran a gps test using the app from market. other than that, everything else is working. what did i do wrong?

Networks detected but will not register

So I had some escapades today, I had my SGS running jellybean, then I tried to change the screen density and bang, bootloop. I panicked and after some odin fiddling managed to get it booting Darky using odin. I was in a room with no signal at the time so I thought nothing of not having any signal, even so I then went ahead and used recovery to reinstall my Jellybean rom since that's a bit nicer than the 2.3 Darky.
Long and the short of it is, I can search for networks in my options and it will find them, but when I tell it to connect to one it says "Can't connect to this network right now. Try again later"
I have tried later and surprise surprise it didn't work. I have tried installing a different radio, clearing the dvalik cache and fixing permissions as well as a few other things. Please can anyone suggest something, this seems to be a very uncommon scenario and it's stressing me out that I can't find any solutions.

Yeah I've checked them and unfortunately they all seem to be in order still, though there are a lot more settings than any website offers things to put in them
same problem
i am having this same problem on all cyanogenmod 7,9,10. i have tried many radio and modem flashes. i can scan and see networks, but i can never connect to them.
have you made any progress?
Problem is EFS folder which tends to do with IMEI.
To fix it you need to copy the backup EFS folder from your SDCARD to the root of your device. (/)
If you don't have a backup you'll have to ODIN back to stock and re-root....etcetera

thx
thank you for the response. I put it back to stock lastnight before bed so i will give this a try.
i have the gti9000m from bell in canada. I updated it through kies to 2.3.3 gingerbread and it all went badly. It would boot up and load to the os be on for a bit then reset. It turned out to be wifi problem, running it on airplane mode stopped it from rebooting. Then if i tried to turn on wifi it would quickly reboot.
So then i tired all the cyanogenmods, which worked it stopped rebooting all the time. however the wifi would connect and work for about a minute then it would drop. doing the
1.turnOn gps
2.turnOn wifi
3. turnOff gps
this would let the wifi work again for about a minute. I tried all the wifi fixer apk, and a bunch of wifi.zip mods, and then ping the router gateway constantly, none solved this problem. Very annoying because i need the wifi working for develpoment of apps. I have spent a great many hours on this problem. lots of people seam to have this problem but no solutions have wokred for me.
So, my questions are....
1. does your wifi work?
2. how the heck do i get mine to work?
back to stock
After going back to stock then upgrading connecting to network operators is fine.
wifi is still broken though
