[Q] Wifi Can't Connect To Networks It Can See - Captivate Q&A, Help & Troubleshooting

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!

Wifi on Cyanogen issues

I just finally got sick of waiting for an official Froyo(Bell isn't about to give me an upgrade anyhow.) So I went to a froyo rom that was based on one of the stock roms. But I figured since I'm rooted anyhow why not play around, and grabbed cyanogen 6.1 and installed it. Then I end up with the issue of its not connecting to my wifi, I have no issues on the stock 2.2 roms. One thing I have noticed is the cyanogen shows the network as wep, but it's actually wpa encrypted. I flashed into it from the stock without clearing it first and it worked until I shut off and came back to it. Any ideas on what might be the issue. I'm fairly new but I did look and couldn't find anything to fix this.
I assume you flashed 6.1 stable version? I have no issue whatsoever on my device (and I also used official froyo previously). Did you wipe all before flashing 6.1?
He said he "flashed without cleaning"...so I presume no wipe. This could be the problem, a wipe is strongly adviced if going to CM from a non CM ROM. Also check the number of WiFi channels set by default in advanced settings of wifi. It is set for 11 and if the router is set to 13 or 14 it could not work

I had the same problem when i was installing CM6.1. (with wipe)
The phone could just se a wep version of my network and not the wpa that i have. But after i turned on and off the wifi a couple of times i suddenly saw the wpa version of my network and after i connected to that the problem was solved. I also did click "forget network" on the wep version.
Hope this will help you

Trying this now but no go. Sometimes will flash it as wpa and then jump back to wep. This is after a full wipe. What I was trying to say was once I flashed in without wiping and it worked for a bit but jumped right back to not working, after the phone going to sleep.
Bump.
Any insight into this issue? Still only reading my network as wep.
Try installing "WiFi Advanced Configration Editor" from the market. You should be able to change to WPA manually with it.
Did you try to reset your wifi router?sometimes the issues came up from wifi router, not the phone itself.
Mine is fine. I share my broadband wifi to my phone using connectify.
The only problem remains is wifi disconnect frequently, but I heard that it's due to a new kernel which I use (.32 kernel)
hope it helps
Ya reset the router a few times, and it still came up like that. I did install the wifi advance config software mentioned it seemed to fix it. I didn't actually set anything up on it and it seems to have fixed it. Thanks.
CM 6.1 messed up my wifi. Wiped everything, but it suddenly doesn't find my networks.
Wiped again and restored nandroid backup of working rom but STILL the same issue now!! Can I flash the wifi drivers again somehow?

[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?

[Q] unable to get data connection

Hi guys,
I'm being annoyed by my SGS about his data connection. Hope someone could help me!
Few days ago I flashed MIUI Mintberry 2.1.20 and everything was working like a charm, but this morning data connection switch failed several times.
I've tried to wipe everything, re-flash Mintberry and even to flash JVU stock with Odin, but I still can't switch on my data connection.
I can't even see any icon on the status bar.
Any idea? Is my phone broken?

Hmm this is strange, so you turned data on but theres no symbol, right? Have you tried installing another kernel (maybe also applying the Kernel Cleaning Script)?
I' ve tried everything with Odin, and at the moment I have a beautiful black screen of death.
Odin cannot recognize my phone... I'm very frustrated
EDIT: Upgrading Kies'drivers, I managed to connect the phone with Odin again, so I've flashed the lastest official stock firmware to check my antennas. In the worst case, I'll be able to go to the shop for assistance without problems.
Have u tried typin ur apn maually?

Sounds like a settings issue. Never heard of anyone have this problem before - I've flashed every version of mintberry including betas.
I just had this issue
I just had this and figured out what is wrong, its a easy fix too! Just go to settings and wireless and change the access point for your mobile connection. I had 2 access points and just switched it to the other one and my data started working again!
Hope I could help
Hi guys! thank you for all these answers!
I've tried to set APN manually, to change custom ROM and custom kernels and coming back to stock too, but still no data connection icon (neither data connection itself).
At the moment, I'm on JVO, the latest official italian firmware, everything is fine but 3g data connection.
Other ideas? Shall i need of Samsung customer service (I hope no!)?
Solved...
MIUI default settings fault: SMS notification has ran out my money and my provider has blocked 3g connection.
My phone is safe!

[Q] Wifi & battery issues on imilka's cm9

Hi folks,
I can't post in the dev section so I'm hoping someone can answer here instead. Searched imilka's thread but couldn't find anything that helped me. Wipe & reflash has worked for others but not me.
Wifi doesn't work for me. It worked when I activated it in the setup wizard after flashing the rom but after the first reboot it doesn't present me with any networks and it doesn't connect to the one I configured. I know the wifi device works because the mac address is identified in the status menu.
Also, battery time isn't very good. Less than half remains after being fully charged then left alone over night.
I have tried a full wipe & re-flash and also flashed the last version released yesterday. Does anyone have any tips or do I just wait for a new version? Seems weird that it works for everyone else.

Indeed, I didn't come accross any of these problems... I don't know what to say mate, might have something to do from whatever ROM you came from, some kernel remnants...but again, that's just guessing...
What I'd do in a situation like this would be to revert to a stock GB, use jBroid's kernel cleaner, and then try to reflash Chainfire's repack and back to CM. That's just what I'd do...
I'd try to do a factory reset first. That way you'll get another chance to setup your WiFi from scratch and see what transpires. If it fails, it's back to basics, most probably. Rooted GB --> ICS Repack --> CM9.
It's such a hassle to reinstall everything again.
I'm downloading a stock rom now and I'm going to try flashing the modem partition. Perhaps the modem in the chainfire repack I flashed before is not 100% compatible with my phone... Otherwise I'll just have to stick to mobile data.
Flashing modem made no difference so it's something with the ROM. Luckily I have a good data plan so I'll just leave it and see what happens in the versions to come. If anyone has an idea, feel free to let me know.
And thanks for your answers guys.
Suddenly it all works. Thank you Google. You're swell!

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
