try to assign staitc ip............it happened in i9003 too

download a root explorer, go to data/misc/wifi/wpa_supplicant.conf and set: update_config to 0 and priority to 1, it doesn't solve the problem but it gets a little better

i had the same problem i did 2 things 1 was after flashing i did a factory data reset and erased SD card (make sure to backup anything you need) and i also went into my Belkin 600N and set DHCP Lease from Forever to 2days.
ive not dropped wifi since and i had it with 4 diffrent ROMs im now using XXKPS 2.3.6

I've set static ip on my phone, switched DHCP lease setting to 2 days, and now testing...
Thanks Guys much love

Here comes super mega answer, which is worth finding Thank You button -
1.) Open dialer and enter *#*#526#*#*
2.) Come back and say that your wifi works without any issues.

i guess he means 528 instead of 526. *#*#528#*#* is the wifi test mode which loads the wifi drivers automatically.

Yeah there are plenty of those codes actually.
for example:
*#*#7780#*#* factory reset
*2767*3855# factory format (everything wiped, also the internal sd card)
*#*#1575#*#* gps test
*#*#1234#*#* pda phone version
*#*#1111#*#* fta sw version
*#0*# lcd test (cool one )
*#*#2664#*#* touchscreen test
they should work on every android device. try google to find more

Thanks mate

So after the tips from Sakindia and BackDaws, when i changed the phones ip to static, and changed the routers DHCP settings, i have no more problem with the wifi connection.
Thanks again guys
I hope, that this thread will be helpfull fo other S+ users

Change title to "SOLVED"

If it is set to static ip and you changed dhcp settings it is only solution for your home network, not anywhere in public, right?

This was exactly the cure for the problem, I can also confirm it. I tried several things, such as exchanging config files between several ROMs, what a waste of time
But I'm still wondering why 2.3.4-2.3.6 can not work with forever leasing time... It's bad.
p.s.: for me no static IP needed for proper work

[Q] Need Help with WiFi

I am running aospmod 9.7.

i can connect to almost any router except for one
I am sitting a few feet from a buffalo nfinity highpower router and I can't even see it with my hero.
The bad part is that the two Iphones that co-workers have can connect without a problem

I am using aosp's stock kernel and I have that exact same router with no issues. I am using WEP encryption. I have no suggestions, but thought if you know what is working it might help.
i got it fixed. that router for some reason doesn't show up if it is configured as an access point.

I can't see the router anymore.
if i restart it i can see it for a few min and connect to it but then it fails.
I tried to wipe and re install 9.7 but that didn't help either.

I have two Buffalos, both set up as access points, and I can connect to both with my Hero.
Firmware issue with the Buffalo?
Unfortunately This is a work router so the IT guy is not giving me access to the router settings. I am going to try a different ROM and see if it is truly the router or the phone.
The IT guy has an Iphone so he is really laughing at me now.
Try changing the wifi setting channel in CM6 go to wifi settings and hit the home button then hit advance and choose try a different channel its 11 by default hope it helps

[Q] Wifi Disconnecting in Gingerbread

My wifi is constantly getting disconnected. I have to reconnect many times a day. This is really getting frustrating. It was working fine(very much FINE) on froyo 2.2.1 xxkb3 rooted and deodexed but after i updated to 2.3.4 gingerbread, this problem began! Is there someone who might be knowing what the problem is????
First i tried stock XXKPH, then i tried after CF root and after that i thought a custom ROM might help so i installed GanaROM but wifi is not working properly in any one of them. It is getting diconnected if i don't use it for like 5-10 minutes. And i have even turned the wifi sleep policy in the advanced wifi settings to NEVER. But still!!

i9001 problem with wifi

hi guys,
i have some problems with wifi.. if I connect my phone in wifi area, after some minutes it disconnects automatically. another problem is the switch beetween 3g and wifi, sometimes wifi doesn't connect automatically.

My wifi works exactly 3 minutes (180 sec) before disconnect. Where is the switcher?
you could also try using a static ip adress...and does it happen when you are connected only to home nework or ?

If you have a time limit on your connections its either your DHCP Lease Time set to 180 or wifi.supplicant_scan_interval (in build.prop) set to 180
Here it is.
Maybe i can replace it with settings.db from KQ1 ROM ?

definitely it's not the reason because this value is define an interval between the scans when your phone is NOT connected to any hotspot and it scanning for a known or open network.

kellermanv, check your PM
jonah666, I don't even know if I can do anything, so don't You be ahead of the game
So, in a brief, the problem is:
since Q7 ROM and upper Samsung improperly do interprets "wifi_idle_ms" value as global WiFi timeout or as after-last-activity timeout instead of after-the-screen-goes-off timeout, as it standard.
Who dare to cure it?
Well, with your value put at 5 minutes, it dropped only when the screen was off after exactly five minutes. if the screen would have been on for 5-6-7-8 minutes, it wouldn't have dropped.
now i tried with value 0, 5 minutes gone and wi-fi didn't drop. i'll let you know in the morning if it dropped or not.
L.E: Nevermore, it dropped again.

Wi-Fi not connecting

When turning on Wi-Fi, it's saying connecting and then disconnected, but below that notification says wi-fi available (status Excellent)
Tried all ROMs CM10, Zeus v7, and UltraICS ROM
With all of above ROMs, problem existed.

if you want solution, you must tell more information
such as, before you have this issue? this happened after what? or when?
this happening only one place or everywhere?
maybe your modem issue? or adsl or whatelse issue?
maybe your device damaged
you should paste a logcat
and tell more information...

It's causing the wi-fi problem.
In 2nd page of v30b ICS user manual, a special indication about wi-fi region wise, maybe that's the culprit for wi-fi problem.
This problem usually happens when you are using a wifi modem with a mac address filtration or something
Try looking in the modem's settings about mac address options

Thanks for reply, but before wi-fi problem I am using it for 2 years with no problem of mac address or anything else, (wi-fi is open without password)
After flashing Zeus, UltraICS, and CM10 alternating with multiple times, get wi-fi problem gone away on CM10 now, maybe if I flash some ROM, problem may arise again.
Now again, no problem with mac address or anything.
try with another device. if it's ok, it will mean that the the issue is on phone side
it's not mac address problem then

[Q] why does wifi always die in DjangoManoucheX?

Okay guys I've got a constant problem with DMX, not just with this version, but I start to get tired of it. So after a day or two of flashing, wifi starts to stuck at "Obtaining IP address", and does not connect at all after that. As I said it's not only with this version (I'm on 1.6.5), I have also tried different kernels, etc, but it's still the same. I don't want to always reflash, but I'd also stick with this ROM as I really like it. This problem does not come up on CM-based ROMs at all. Thanks for any tips.
Btw I've also tried static/dynamic IP settings, I've changed a router (not because of this), reseted it many times, so not that I didn't try anything at all.
I never had a issue... Have you installed the rom with full wipe?
Of course I did a full wipe, didn't restore any system apps, and as I said it works perfectly for a few days, then bamm! I was playing SongPop, started a game with someone and it stopped when downloading songs.. then I went in wifi options and it showed this IP bug once again. By the way I've just finished reflashing (now without full wipe), and it doesn't even connect now. I really like flashing ROM's etc, but not the same one all over again lol.
Finally I could set static IP on my phone, works now, Thread can be closed. If anybody has the same problem (I've read I'm no the only one), then holla at me!
I'm having a wifi issue from the day i have purchased this phone my wifi always go in the sleep mode don't know why no matter which ROM i use it goes to sleep after the screen is locked or after 5-6 sec of no use of phone.
i'm the only one having this prob i guess.. I thing its an hardware issue, not sure, hope some1 could help me out ^_^
Note: i have kept wifi policy sleep never
Problems with wifi is a kernel issue.
Its adviseable to post which kernel is used
Well I wouldn't be sure, as I was using Kowalski kernel and KoB kernel too, both had the same problem, and only on DjangoManoucheX ROM. But it seems to work now with static IP set.
akash.mahadeshwar has his ROM/kernel stated in his signature, too bad I can't help you.
Lol I don't know if its hardware or software issue but changing rom or kernel dosent fixes it :-/

have you tried changing your wifi to static ip?
if not, then go into wifi settings and long press/modify the one you cannot connect to. Go to advanced settings and change from DHCP to Static IP. Run Windows commander (just type 'cmd' in the Start Menu search box), and type 'ipconfig /all'. It will show all the informations you need to type to your device's wifi settings. You can give almost any number to the first IP field (when your IP getaway is, for example 192.168.7.1, you only have to change the last number to any you want to, like 192.168.7.155.. but the best way is to get the IP number your device used before wifi got stucked). If you can't see DNS1 and DNS2 in your ipconfig, then you have to go into your router's settings (in browser), that will show them. If you type everything correctly, then Save button won't be greyed out no more, and voila. Wifi works perfectly for me since then. I hope it helps.

Changing Wi-Fi to static is far from being a solution; at best it's a workaround.
It's probably related to LG code, used to compile the module loaded by kernel.
I'm not sure if the problem you're reporting us exactly this: I have a brief disconnection/reconnection sometimes when I unlock the phone (Wi-Fi suspends policy sets as never), but this it's not annoying me to much because while sleeping it's connected, and the 2-3s after wake-up is not to much.
Do not say "thanks"; just press it under here.

No, my problem was I could not connect to my wifi AT ALL. Couldn't even do it after a full wipe and reflash, so using a static IP is a solution for me, as it works for 3 days by now. It can be related to the stock ROM's code, as CyanogenMod ROMs don't have this problem for me.
Try flashing KoB kernels again, in mine its wifi work correctly
