Try rebooting your router.

ive done all that. i just went to a few friends houses and it connects fine to all of their wifi one being the same ISP. so something happened to my router or accidentally changed a few settings. other than that i have no clue. the error i used to get is disabled secured with wpa wpa2 psk, and now after messing with a few things it just says disabled.

Used to be a common issue in 2.2 based ROMs, atleast in the ones I tried. Switch to a 2.2.1 based ROM.

When mine does that I usually make the phone forget your router, disable wifi, unplug router, plug it back in and then turn wifi on and find your router. Works for me hope it works for you.

updates? mine has d same issue, that's y Im connected via static ip now

I figured out how get it working. I download fxr wifi fix and rescue from the market and it actually fixed it lol. Basically the process put you in air plane mode, and removed all the previous remembered wifi connections. It has to do something else because I tried that a million times manually but I'm not complaining. Worked like a charm
I know some people use roms. But I haven't really looked to much into them yet. Any recommendations? I've seen a few on YouTube but some major features were not working. And where do I d/l them?

that solution worked for me. thanks

[Q] Do have the same problem? (wi-fi)

Hello.
I've tryed many ROMs that are here in xda: Froyobread, GingerDX, GingerXperia, kuyaDROID, xGin, etc... And now I am using Stornmix with stock kernel.
But in all this ROMs I've had always the same problem: wi-fi.
My wi-fi connection works good during 1 or 2 minutes. Then it stops working and I can't use the browser nor the market or other app that uses internet connection.
When I turn off and on again the Wi-fi, the internet connection comes back good, but the same happens after few time.
I even tryed 1 wi-fi fix that i've found here, but didn't solve my problem.
Have you guys experienced this problem too?
Any clue how to solve it?

It is already that way.
Always have been.

Delete the remembered connections.Sometimes too much of them cause problems.

There's a compatibility issue with WPA-AES encryption. It's been discussed here and somewhere else (official SE forum i think). Not much to do about it...

Scratch the "AES" and make it "EAP" ...
IF AES would be a problem I think no one of us could connect to their access points as WPA/2 actually uses AES for encryption ...

I had a similar problem with GDX back in the days of v012 onwards. The WiFi connection wouldn't completely die but only go through a disconnect/reconnect loop every 2-5 minutes (unless I used "Wifi Static" to set a static IP configuration for my access point).
I solved the "disconnect/reconnect loop while using DHCP" problem by switching to another WiFi channel (my Access Point automatically determined channel 1 to be the best choice ... I later on switched to channel 11 and the problems fixed itself) - sounds weird, but worked.
You may give it a try.
On the other hand we already had weird WiFi problems which really didn't go away unless one flashed back to stock (where the WiFi suddenly worked flawlessly again) and changed over to the custom ROM again from there.

Thank you for your help, I'll try that and see if it improves my wi-fi.
And yes, as I can remember, it worked nice with the stock rom.

[Q] Wifi on cm9, poor connection

What's up guys, first of all I've looked up for that problem on the board and none of the topics are helpful.
Well, I've got SGS with CM9 nigtly 2012-05-06 with the IcyGlitch kernel. I've checked different modems and kernels and nothing. The problem is connected with the wifi. However it is only about my router. Somehow my phone and router don't like each other. The wifi speed is really slow, to download something is a miracle, facebook sometimes even doesn't want to log in. The problem started after I installed cm9. I've tried many builds of CM9 and none of them helped. I don't wanna wipe the phone and install another rom, I just want to fix it, if everybody can work without any problems, I also can. My router is D-Link 524. I've tried other cell phones and they work fine with the wifi. Also I've tried other wifi connection like at my university and it works cool.
What can you advise me to do ?

Can't get WiFi tether to work

Hi,
I can't get WiFi tethering to work on my device, even though the ROM specifications imply that it is compatible and tested to work.
Basically, the problem is that when I activate the WiFi tether, the process goes smoothly and it becomes active, but none of my devices can see the SSID of my X8. I tried to scan for it both with my laptop and the Xperia Arc S device, and wasn't able to find it, albeit my laptop on one occasion actually managed to see it and connect to it successfully. When I tried the next time, the X8 wasn't there anymore.
I tried both the Wireless tether for root users app, and Barnacle wifi tether. Both have the same issue. I've also tried rotating through the channels and adding encryptions.
ROM is FroyoPro v2.5 and kernel is stock. I've read somewhere that stock kernel doesn't support WiFi tethering, but keep in mind the creator of the ROM tested it on stock kernel successfully, and I actually managed to connect to the device on a single occasion. Something else must be the issue.
Anyone else with the same problem? And possibly a fix?
EDIT: I've read that most phones can't connect to your WiFi tether because it's ad hoc mode. Is that the case here? And if it is, is it possible to make our X8 broadcast in infrastructure mode?
Had a few more successful connections to the laptop. No luck so far on Xperia Arc S.

As far as I can see, an app called WiFi tether is the only one capable to set up an infrastructure mode, but your ROM and kernel must support it. Also, most phones support searching for infrastructure networks and don't support ad hoc at all. I can't unlock my bootloader so I can't investigate this any further.
For now, Barnacle wireless tether is the only one that works for me, probably because it supposedly loads its own drivers, and I can connect to my X8 only from a computer.
I'm really getting annoyed with the stock kernel. One day I'm going to get drunk somewhere, and when I come home I'm going to attempt to unlock it. I swear (11w41)

You must flash "Wireless Tether for FroyoPro:" it is in second post of froyopro thread: http://forum.xda-developers.com/showpost.php?p=20494413&postcount=2

I did try that, and it doesn't work even though the fix for tethering is installed in v2.5. Also, another thing that is annoying with it is that I have to reboot after each use, or else normal wifi wouldn't work. Barnacle is the only thing that works at the moment.

Good morning everyone.
I'm looking for help from anyone who can help me.
I'm looking for a rom that works well wi-fi tethering.
Barnacle does not work for me on all roms I've tried.
I'm a little desperate.
I'm waiting for someone to help me .....
I've tried much more rom like JB and ICS, but nothing to do.......
At the start, it works well, very fast, but after 5 minutes the display goes black, the network is disconnected and no longer works.
HELP ME!!

[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
