Galaxy S freezes when turning on wifi

Hello , i have huge problem with my Samsung Galaxy S.When i turn on wifi , my galaxy s freezes , and only 1 way is to reboot telephone , or take battery out
I dont have this problem at home.When i use wifi at home everything seems to be ok it can easily connect to my router .Problem starts when i go to shops/schools when i want to connect to others wifi my galaxy just freezes :/.
Originaly i bought it with android 2.2 , i had the same problem with wifi.
I installed android 2.2.1 - also the same problem .
During last weekend i installed darky's rom 9.1 and it didnt help
Do u have any ideas what to do , or just my galaxy s is broken and i hae to get it back to samsung tech center ?

Have you ever done a factory reset on the phone? If not that may help otherwise it may be hardware related. Since 2.2.1 have not had a single problem with wifi.
Sent from my GT-I9000 using XDA App

Yes i was trying factory reset few times also i was trying to clean cache , problem still exists

Sounds like possible password problem, delete all your passwords and wifi connections .
Reset up home connection then try external where you have the password and a strong wifi signal .

I deleted my wifi profile , and problem still esists when im trying to find wireless networks in shop galeries etc..

I have almost the same problem but it happens with voodoo and not speedmod and when I turn it off

Today i made total wipe of my galaxy i downgraded it to official clean I9000XXJPU without any speedmods voodoo , i'll let u know tomorrow results .If it won't work ill try to use I9000XXJPX than ill test clean I9000XXJPY.Ill let u know my results .

Nop i don have password , my galaxy s just keep freezing while searching for wireless networks ( secured , non secured ) . When im at home , i can connec tto my router ( secured with password ) without any problems .

So its not a connection problem then .
But a WiFi search problem .
Time for it to go back to Samsung then .

Problem solved !! but i had to give back my Galaxy S to Samsung service :/
Problem was mainboard - number of part A/S ASSY-PBA MAIN_GT-I9000(COMM_8G)_SVC .

''not registered on network'' error please help!!!

ok straight of the bat im a total noob with odin alll android firmwares and phones etc.
much to your displeasure i am an apple fanboy... but i really need your help guys!
my situation is as follows: i bought a samsung galaxy s4 relatively cheap of an aquaintance, i used a link on a forum here to see if it was blacklisted and results say it wasnt, i bought an unlock code and it worked ''network unlock sucessful'' YAY... then i try and call the number and after a while im redirected to 02 messaging service. next i try to dial out and i get hit with the not registered on network error. now funny enough i get a warning triangle saying no service yet i get service bars and even 3g; also when i select a network manually and choose 02 it says registered.it also says emergency calls only.
basically i need your guys advice and solutions...
why it may be this way: well as soon as i got i rooted it and it worked i believe this was on 4.3, pretty much as soon as i had done this it was throwing this error at me, after a long time i came back to it and researched more into this golden restore, and the phone was locked to ee now there modem doesnt allow access to the service menu so i changed my modem, when flashing on odin i have tried pda and phone,,,(idek what im doing) i have a GT-I9505 on rooted 4.3 (not sure which root) with baseband: I9505XXUEMK8 and a build number:JSS15J.I9505XXUEMJ8
basically im asking one of you guys how do i reset this to stock 4.3 by flashing with odin, its originally locked to ee but now its been unlocked so can i use btu not ee files? have any of you had this problem and how did you overcome it?

[Q] i9505 LTE modem flash issue

Hi all,
I've had my phone locked on Tele2 (CRO) network which I needed to unlock to be able to use T-mobile SIM. I've used Odin 3.04 and followed the instructions to update modem to I9505XXUFNB9. I've managed to unlock the network this way and use my new SIM but the connection (both phone and mobile data) kept switching on and off constantly.
After that I've tried another firmware, namely I9505XXUFNDG for T-mobile but the problem now is that mobile is almost always off with no possiblity to connect and WiFi is blocked completely (security notification "Your device's security has blocked an action").
Basebands registered properly after every flash.
Phone is not rooted and me not being a power user would just love it to work as it was intended to
Followed the guide, all firmwares downloaded from here
Appreciate any help.

Might be onto something. After reading through this post seems I need to apply WiFi fix but I cannot tell which one to use for my phone (I9505XXUFNDG) as it's not posted. Kernel version 3.4.0-481100.
I've tried I9505_WiFi_FIX_MDM.tar and I9505_WiFi_FIX_MDF.tar but they just messed up the phone completely.
Thx a lot.

Hi ,
you should flash the fix for the modem you have installed , try following:
Flash another modem from the list there
Now flash the modem wifi fix for that modem
If still in trouble re flash stock and start all over again.....

Thx, did just that and now it works properly.
Much obliged.

a problem started to show recently; when i select LTE/WCDMA/GSM for auto connect network mode when the mode switches due to signal availability it doesn't get reconnected. i.e. while under LTE it works fine but if i move and get out of reach it should automatically switch to slower network which it doesn't. this works fine if i select WCDMA/GSM then the switches are fine but LTE is not available under this.
one more thing i noticed since i'+ve flashed the phone is that the upper part of the phone gets very very hot (a lot more than before). since the flash i've also had to replace a microSD card which died within weeks (not necessarily connected but worth noting).
any suggestions welcome.

Strange WIFI issue,please help.

Hello guys,im expiriencing strange issue with wifi in last couple of weeks.Im sorry if someone already posted thread with this issue,i couldnt find it anywhere on XDA.
Here is the problem:
i have sm n9005 and i was using stock 5.0 first,and then decided to try some custom roms.It was all good,and i changed couple of those.
At one point,i did firmware/bootloader update for some of the roms,i cant remember which one exactly,and phone started to act strange.
It could only see and connect known wifi networks (my home and work ones) and as much scanning i used,it simply can not see/scan other
networks in the area.Its really annoying.When i do factory reset/data on any rom,its all good for some time,sometimes like few hours,sometimes
few days,but it all gets f_____ up again,and i can only use networks i already used in the beggining.I tried few times to flash stock rom via Odin,
it was all good,but after some time (as i said,sometimes less sometimes more time) its acting strange again.Maybe im flashing wrong stock rom
in Odin,i cant really tell whats going on.Current baseband version is n9005xxugpof3,if anyone knows how to solve this,please help,i will provide
any data needed in order to solve this annoying problem.Thank you in advance and God bless you!
p.s.
here is the version of stock rom i flashed,its N9005XXUGBOA5_N9005XEOGBOA4_N9005XXUGBOA1_HOME.tar and i think its Poland version
or something like that.

update:
tried to flash original italian ITV stock rom,all worked fine for a day or so,and it all went back wrong again :/
Phone is not showing any WIFI network,but when i add it manualy,which i tried with my home network,
it works well.Also,its sending me notification when available networks are on,but when i enter wifi
section,list is empty again : / Mac adress in my wifi options is ok,and IP adress is unknown.
Any ideas,guys,i would really appreciate any sort of help?Thanks!
