[Q] Samsung galaxy i9000 won't connect to wireless any more - General Questions and Answers

Hi all,
I have a Galaxy i9000 and it won't connect to wireless. It used to connect just fine, then one day it stopped working. I ignored it for a while (3G still works) and once I finally got around to trying to see what had happened, I could see that the phone does connect to wireless networks (at home and at work), but once it had authenticated to the network, it would fail at "Obtaining IP address from <network name>". There's no error message, but the phone just sits at that stage forever. Not obtaining an IP address makes it pretty hard to connect to a wireless network
I don't know what happened to make this problem occur, it's been about a month now since it happened. I have AdFree installed on the phone, that writes to the hosts file, right? I suspect that it may have been a hosts file update which had caused this problem, but I'm not sure.
Does anyone have any suggestions as to what may have caused the problem?
Thanks!

what about reflashing your phone?
so you have everything stock
if this doesn't solve the problem then contact a service, or if you have warranty, just send it back...

same problem
The funny thing is is have exactly the SAME PROBLEM ... SINCE the same time?!?!
mybe we got some kind of virus for phones? ... altho i do have anti viral software on the phone. and i didnt upload any kind of stuff on it for at least half a year.

try resetting your phone to factory default

I am also experiencing similar wifi issue..except I get pass obtaining ip address it's after that I get error message "authenticate problem".??
My brothers works fine connects within second on home wifi, when I connect on same wifi I get error message..I have tried restoring previous wifi data..I have done phone reset too but nothing works

[Q] wifi problems

im having trouble connecting to wifi. my phone just hangs at obtaining ip address and then eventually fails. ive tried with many different wifi connections not just mine. all the same. Anyone else having this problem?
Yes same problem here.
It seems a general problem like the GPS.
I found out that depending of the router brand it works better (for example, no problem with a linksys).
To go arround the problem you can try this:
- go in flight mode
- activate wifi
- when you have a wifi connection (test with to browser) reactivate the phone
I hope it helps

Bring the phone back, and get a replacement. I have had no such problems with my Captivate.
I do notice that the WiFi signal isn't as strong as on my iphone's in the same area of the house though.
still not connecting.. maybe i messed up a flash with odin. i will try that again
the problem started when i flash jm5
problem solved reflashed

[Q] Wifi signal?
Does anyone get a weak wifi signal with their Nexus S? Whenever I connect to my at home wifi I never get full bars and something I'll just randomly lose signal. Also it seems to go pretty slow. I used to have the Mytouch4G and it work flawlessly with the wifi. Anyone else having this problem?

OMG yesss I do.
Just about a room away I loose signal, almost completely. = 0
IDK, but I see more flaws every day that passes
Mine's been working fine over Wi-Fi. I'm pretty glad it does too, because my only data option with it is Wi-Fi..
Sent from my Droid using XDA App
Wifi has been working great for me. It reconnects automatically and doesn't drop. The signal seems on par with my nexus one.
Speed wise, is it on par with the 3G network?
[Q] Wifi does not work anymore after rooting :(
So, I unlocked my Android 2.3.1 and rooted it ... But if I click on wifi so I could connect to my modem it says Error and wont even search or anything. I tried reseting too but still no luck .. What is the problem and how to fix this ??
That's odd, I didn't have any issues with wifi as I connected to Android Market to downloaded ROM Manager during my rooting process earlier. Have you tried flashing a custom ROM on your device to see if it'll fix it?
No I didnt, would that work? .. A friend told me to install a new "kernel" but I dont want to overwhelm my android with custom made kernels .
your problem is you used one of the quick methods of rooting your phone, which used a kernel that wasn't from the exact rom you have.
if your on stock 2.3.1, you will need the stock 2.3.1 boot.img, and then you'll need to root it manually the long way via adb command line. search the nexus s development section for how-to's. they are all there.
i too had this problem, had to install MoDaCo ROM to fix it, but i dont regret rooting, i now have custom rom and over clocked cpu on the nexus s
you have two options, either to flash NANDROID backup to un-root and return to stock or install a custom ROM, i choose MoDaCo bcoz of its UI, it looks and feels just like the stock one.

Yes, that's the point of MoDaCo roms, to make minimal changes to the look and feel of the phone, but to improve performance with his custom optimizations.

[Q] Nexus S Wifi Settings - force close
Hi all,
Just got a new Nexus S - all was well at home. Took it to work today and noticed something very odd. It was fine until entering the wifi settings menu - at which point it dramatically slowed down. I got two 'not responding,close or wait' messages before being able to join the network.... all other settings are fine - just the wifi area.
Weird - wondering what could cause this... too many wifi networks broadcasting (am in middle of London)...?
Anyone seen anything similar?

Too many WiFi around you shouldn't cause that.
Try rebooting and setting again if you haven't already.
Hmmm - rebooted and still have the same issue. At home, or even a block away from the office it all works fine. But in the office itself, although it connects and uses the wifi fine, the settings page is VERY slow to load and gives me the wait/force close message.
Out of interest - I also have 'wifi analyser' from the marketplace. This too is very slow and unresponsive when in the office.
So - it is definately something to do with the wifi here.... but have not got a clue what. Before I join the wifi, or when I am physically somewhere else it all works fine.
Wifi is WPA-TKIP, the key is a very long jumble of letters but surely that is not an issue.
Strange eh!!!

[Q] Possible WiFi problem?
Hi there, just bought a Nexus S, also used to have Nexus One.
The thing is for some wireless networks even though I enter the password correctly, it says connected and still there is no connection at all. (I mean browser tries to connect but at the end it says page could not be found) I even tried with an ad-hoc network that I created with my laptop but still the problem exists.
At home I'm able to my network without a problem. The type of network I'm trying to connect is: WPA2 Personal with AES. Is there any known issue about AES at Android system? Afaik there is no way to change the encryption used right?
this might actually not be a nexus S issue.
some modems/switches/routers are configured to block certain devices/applications/package's
we have a modem and router with both wifi.
but my psp/nDS cant connect to the modem,but can connect with the router

i have a similar problem. My Nexus S connects to my router only within a few hours after a router reset. Then it stucks at "obtaining ip" and never connected before I do another router reset.
My home wifi is WPA2 type, and for WEP type wifi my NS never got connected.

GT7+ Wifi Error

Hej there,
tried to connect at work to our wifi router. First it was just searching for ip adress. After this Wifi turned of and just shower "error" down under the wifi activation point.
Now I`ve tried to reset to factory default and many other things. Everytime I turn my device back on I`ve the same message and wifi still doesn`t work.
Please help me. Its driving me crazy!
(sorry for my english... stupid german )
Thanks guys
1+ I'm having similar issues with the WIFI, but is it only on some routers (not all).
also interested in any help...
There`s something in the internet that says you have to delete the dhcp_list file in this folder "/data/misc/dhcp" but I don`t know how to connect from windows in the root system of my tab. I have rooted my tab but now I don`t know how to install apps without wifi. Anyway I had it rooted before and the root explorer doesn`t work
maybe someone hast good suggestions.
Is there any way to force a firmware update? Or is there another way to delete or reconfigure the wifi connection. I can`t connect to any wifi point
OK,... good news. Found a way to fix the Wifi Error.
Download Odin3 and the actual Firmware for you GT7p. Then put the device in download mode and connect to the computer. Flash the firmware again and then make a factory restore in recovery mode.
Here we go... on my device everything is working fine and i rooted it again.
Hope this helps.
Found the tutorial I used here in the forum. Just search for p6210 firmware and be happy
Had a very similiar problem just with my home router for 2 days (first time connected and remembered, but after that still searching and out of reach...). Always had to turn off router and turn it on. Battery was drained in couple of hours due to this. Then just rebooted and uninstalled launcher I was using and voallaa...Since then wifi works properly everywhere (btw with very strong signal in comparison with any other device I had before).
So dont't know exactly what happened, but so far so good...

Galaxy Express 3 (J120A) Not Connecting to WiFi - Cycles Between "Connecting" and SSID Not Appearing

I bought a Galaxy Express 3 (sm-j120a) on Ebay (new condition) to use as a backup phone. I began the setup process and tried connecting to my WiFi. I put in the correct password but it will constantly cycle between showing "Connecting" underneath the SSID, then suddenly the SSID disappears, then suddenly it will reappear and show "Connecting" underneath, etc. It will do this indefinitely and will never connect. If anyone has experienced this issue before and knows how to fix it, I would greatly appreciate some help.
One thing I haven't checked is whether I could update the software of the phone to the last available update. I wanted to hold off on putting in my sim card because I have a nano sim and I think the phone takes a micro sim and I don't have an adapter yet. Is there a way I can download any available updates to my computer, then send the update to the phone via a USB cable?
Thanks!
i ran into the same thing a while back with an old android phone, a samsung j120a. one day its wifi stopped working with the att modem i have, a bgw210. behavior was the same as what you described. every other wifi device in the house worked fine. tried every standard trouble shooting thing you find when you search this, including factory data reset, nothing. got hold of another phone same model... it also failed to connect to wifi on this modem, same thing.
the answer-> i resorted to playing with the wifi settings on modem, and found that the problem was with the wpa version setting- it was set to wpa 2 by default when i found it. i changed it to the setting that accepted both versions 1 and 2, and the phone's wifi now works again.
i assume at some point att updated this modem, and one of the updates was to change default setting on the wpa version, probably because wpa 2 is supposed to be more secure than wpa 1
just replying because i hate searching stuff like this and finding nothing but people asking roughly the same question without getting any answers. hope this helps somebody searching this in future
