Hey Everyone
I recently installed XXJVB (2.3.3) onto my sgs and it works really well. my only issue is that the wifi connects sometimes and sometimes it doesn't. This happens at home often and is really annoying.
Does anyone else have this problem?
And does anyone know how to fix it?
Thank you for any reply's
I haven't experienced it.
First thing to try before you go any further.
Turn off everything that connects to your Wi-Fi router. Unplug the router from the power supply for a minute, then plug it back in. When it boots back up, see if the problem still persists.
Also, Have you tried a factory reset prior to or after flash?
had that issue when I played around and installed a cpu tool from the market: my wifi acted up same as yours. As far as I could deduce it was because the power/sleep settings were altered -- beyond my pay scale. Uninstalled the offending program and rebooted: the whole system was hickey and media scanning was an issue. So, did a recovery restore in cwm and all is well again.
Suspect the issue is the set up for power management. sleep policy and the other internal setting sin the kernal being out of phase with each other. Do a retore to the last stable system you had.
I have also leanred the value in doing a complete backup before I play with any new themes and mods: that way restore bails you out!
Did you notice that on version 2.3.3 wifi sensitivity worse that on previous version?
Using "Wifi analyzer" application I found that on Gingerbread kernel signal weaker then on 2.2.1 by about 10 db.
I've tried to use modem JPY (from 2.2.1) instead of native JVK but it didn't help.
It looks like somewhere there are wifi parameters that should be configured properly.
SOLVED
Thank you everyone for you input
@electrotune1200
Thanks for your idea's. The whole turning router off and on worked. i feel rather stupid cause i have to do that often so that i can get my laptop to connect, never even crossed my mind to try it for my phone lol.
Thanks again everyone

Hello, Not sure if has been posted, but i cannot seem to find an answer.
I've flashed to to CM 5.0.7.1 and i've noticed that my wifi doesn't seem to stay connected. I can connect fine and use wifi, but if i leave my phone sit for an hour or so my wifi will disconnect. I've checked my sleep policy and i DO have it set to never sleep.
I can't confirm if this was happening also before the flash.
Any info woudl be greatly appreciated.
Thx
This is an known problem with 2.1 and 5.0.7 doesn't help fixing it. There is no fix for this i'm affraid other than installing an app that automaticly connects you to Wifi again when the phone drops the connection (don't remember the name). If it really is a pain for you, upgrade to Froyo coz there it is fixed.
Hi,
let me thank you for all the help you may give me.
The problem is i get stuck on obtaining ip address or the cell doesn't even try to connect automatically so i have to manually start the wifi connection to the network after turning on wifi.
The problem of my SGS not connecting automatically is rare, the first is not, it's actually quite often.
I looked through all the guides and sugestions but i couldn't find any permanent solution for this problem.
Note: I've used the AllShare app but sometimes even that doesn't work.
Thank you for all help
The same problem kept happening with me. Some of the fixes which I tried were
Change channel on router - didnt work for me
Use the allshare app first - worked
Set up a static ip in advanced settings - almost always worked
But I have found that I didnt have this problem with other routers, only mine, maybe because of a power problem with the router.
Many of baffling errors are usually caused by bad input power to devices.
Hope it helps
Thanks for the reply, the problem is that i use it alot on my university, where i can't do any changes to their router (or use static IP).
Also the AllShare app is indeed a fix, but only if used every time i think. I'll do some more testing, this problem is really annoying and that's a shame because it complicates the use of most of the smartphone capabilities.
So if anyone else as another solution i would be glad to hear it.
Also i'm on stock rom installed by my operator Vodafone (had the same problem on JPY).
Edit: After a very quick test, it seems that using Allshare once does work, but i had the impression that sometimes it would be needed more than once (even without rebooting). TY for the tip.
Update:
After some more tests i came to the conclusion that at home i need to use AllShare every time i want to connect to my network.
This seems to be a problem affecting several users of SGS, does anyone know the answer to this problem? Or at least an app that minimizes it?
It's quite bad and very frustrating. Thanks, for any and all help.
I had the same problem with stock Android 2.2.1 on 3 phones all Galaxy S. Dropping the packages on voip calling, internet was slow most of the time. I use a linksys wrt54g with dd-wrt, I never had problems with any other devices.
My problem was solved when I installed GingerReal. Also on Miui I didn't had any problems with the wifi connection.
Maybe is just the stock driver incompatibility with some devices.
Thanks for the reply,
I've only had bad experiences with flashing, last time i did everytime right and Odin just hanged, i almost had a serious problem in my hands.
Since this is probably the first and last good phone i'll ever have, i would really like not to kill it (also some people in my family would be very disappointed, it was a gift).
So any workaround? Sorry i'm so insistent but i think that are a lot more people interested in this. TY.
Here is the deal,
Phone worked pretty well since I bought it. I changed the ROM a couple of times and everything went fine.
But at some point, something changed and when now I switch off the wifi, the data connection doesn't work anymore. Also, as other users complain, it occurs when the phone enters in sleep mode.
Entering in Airplane Mode and exiting seems to solve the issue. Also, switching from 2G to 3G (and viceversa).
Things that might help:
I did some research and it seems strongly related to the Android 2207 Issue (you can google it, I can't post external links yet sorry)
It happens with every ROM that I try: CyanogenMod, MoDaCo and now with MIUI.
Also, it happens with BB 622 & 725 (with respective RILs). With 502 I don't remember having this problem, I would try again.
If someone else has this problem, share it with us. And if anybody knows how to solve it, it would be great
Thanks!
Hey there!
I recently rooted my I900 (which I had never updated before) using SuperOneClick and everything worked just fine. Now I decided to update the firmware to 2.3.1 using Kies and it worked(my root is gone, but I knew that), but now I have run into a problem: I lose my wifi connection every 40-60 seconds or so, which makes online games or downloads impossible. The Wifi symbol dissappears for a few seconds and then returns, the internet works again instantly, but, as I said, any download or the like is cancelled. I tried getting a static IP adress and turning WLAN standby mode off, but to no avail. What seems to be the problem? What can I do? I would like to fix that without formatting anything, if that is possible.
Thank you very much in advance,
WittyWhiteFox

why not update it to 2.3.6 First, normally KIES will update to the latest for your region, so check here for your region or use webversion of Check Fus 2.0 ROM Downloader
Thanks for your answer.
In fact, I already have updated to 2.3.6(instead of 2.3.1), I made a stupid mistake there, sorry ' bout that.
But I managed to fix it, turns out my static IP configurations where somewhat off. I used a guide I found (but can't post here because I'm new) and now everything works just fine. So, yeah, my problem's solved, sorry for wasting your time. ^^

So now you can close this thread.
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
