General Wifi-Connection-Lost-Bug solved - LG Optimus 2x

Hi everybody,
I've solved the Wifi-Connection-Lost Bug!
It looks like that it is an general Android Bug, because this problem persists also in the official ICS Stock-ROM and some other devices, like the Samsung Galaxy Series.
What could you do? It's easy!
Just go to the Wifi-Settings and deactivate DHCP. Instead of that, use a Static IP-Address and make sure that you also set the DNS2! By default, there is an IP like 4.4.4.4 or 8.8.8.8, overwrite it with your Router Gateway-IP.
In my case, I've the Router Gateway-IP in DNS1 and the Access-Point IP in DNS2. My Router and Access-Point are both single devices. If you dont have a seperate Access-Point, then try the Router-IP again. Oh, and don't use a hidden SSID!
I've got 2 LG P990, one of those has the original Stock-ROM (Android 4.0.4), and the other device works with the latest Cyanogenmod (Nighly from 24.02.2013). Both devices have the same Wifi-Bug and it could be solved. Yeeee-haaaa!!!
Maybe it works on your device too?!
:highfive:
...sorry for my bad kraut-english

[Q] X1 - WIFI problem, connected but not working

Hello to you all
I tried to search, no luck. (maybe just missed the solution if any)
I have problems with wifi.
I can connect to wifi network, (ip is set to device, I can see it in router statistic) but none of the programs that connect to internet.
opera, iexplorer, facebook...........qGPS... are not working. like no connection.
I am using Energy.XPERIA.23678.Sense2.5.Cookie.Aug18, and same happens on my other X1 with Energy.XPERIA.21903.Sense2.5.Cookie.May.09
I also tried other roms. on original it was working I flashed other roms and I have this problem. tried too many still the same problem.
I always erase all (tool29 or how its called) before flashing, always hard reset.
my radio is: 1.14.25.55
I tried to connect to different networks, still the same. even on my home network (that I know all configurations) its not working.
thank you for help and your time.
---------------
its definetly not the router issue, tried restart all things. I can manage my router (I can see the device connected in router table), I tried to set wifi on X1 to performance also other way to quality(or how its called). no luck. but its not router issue. I tried it with open router (no security at all- diferent devicess can connect.), also tried to set different wifi standards no luck.
I have the same problem on 2 phones both are X1. tried different roms. still the same. my other HTCkaiser can connect no problem.
It's occurred in my Vaio. Hahaha. I thought it's the router issue,

No I mean, I have the same problem like yours but it occurs in my Vaio not X1. Not so sure why but I think it's router issue, it's not your device's fault. Just opinion.
In standard communication manager set max performance for wi-fi. I don't know where is it on energy rom but must be in windows folder.
(Sory for my english)
same
have the same problem with one of my x1s after I've flashed an energy rom/ It's not the routers fault, the other X1 works fine with it /So, is there any solution for this/ have tried a lots of roms after that, but it didn't solved the problem/ The x1 connects to the routers but can not use any of them / The routers are all unsecured, no key needed to use them.
I had the same issue, my solution was to change the settings by taking firewall off router through your pc and make it a open network till you connect wifi from your phone to the router then once thats done and you have tested the internet then you can switch back on the firewall settings and your good to go.
Yes!!!

Don't mean to interrupt, Change the router performance (Router is the WiFi not the phone X1) different router (WiFi device that shares internet) means different setup.
Out of topic, contrary from mymailx, I have different problem. When my X1 can use the WiFi well, but my tablet and pc can't use the WiFi, it is connected but can't access internet (yellow exclamation at WiFi icon at taskbar). odds. I have restarted ever settings.

[Q] wifi problem (azusaROM 1.04.29062010)

hi, I bought a second hand tattoo last month, the previous owner installed azusa 1.03 on it but wifi didn't work at all (I was able to switch on the wifi) So I flashed with the last Azusa ROM (1.04).
first the wireless worked fine, but, I think after a reboot, the phone wasn't able to get IP address on every AP I tried. however I can connect a wireless network if I set a static IP on the phone...
any idea to fix this, please?
(sorry if it's a problem to post it a second time, but I don't know if the problem come from the ROM or not...)
Well, I have the same problem with the wifi. It sucks cause this rom is really fast and non-functional wifi is the only deal beaker... Try to contact the developer Coburn and ask him. If you reach him, tell him that I already posted a log of the problem on the project's site.

Any news on this? I really like the ROM but not having wi-fi completely kills it =\
None so far... And I doubt that there ever will be a fix for the issue. I abandoned this Rom.
hi, I didn't find a real solution for my problem... I just installed an app named "wifi static" and I set the few network config I use usually, it works, but I can't connect to any free hotspot easily.

[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] 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

zuk z2 pro wifi problems

Hi there!
I have this zuk z2 pro monts ago and it comes with a custom shop rom. With the custom rom everything worked perfectly except that it doesnt have the option to update its system.
So to be able to update its system, i flashed it with a stock rom and it updated without any problem. Then im starting to notice that when i am on my wifi, some apps seemed to have stopped to connect. So i tried it on data, and it worked fine. Tried to connect it to another wifi of another isp, it works, but when im back on my providers wifi the problem still there. Also tried connecting to other wifi with the same isp as mine, and yeah, still apps dont run.
Now, is it possible that the stock rom is being selective with isps when running wifi? Anyone had this very weird problem like mine?
I have the same problem. When I connect to the wifi from my provider it fails, disconnects, stops working.
But I found a solution (for me): I added an extra wifi-router to my adsl-modem. Now I don't have that problem anymore.
Why this is happening, I don't know.

I think that this happens because Zuk z2 is configured for China region at wifi. You can change the region at custom roms but stock rom doesn't have this option
Other similar problem

In my case I have a similar problem. My Wifi not work in 2.4Ghz frequency only in 5.0Ghz. Somebody can help me? I already flash various custom roms and stocks (using qfil) and basebands (from basebands colections) and one million of possible things. Can would be hardware problem?

Try to flash aex or lineage. At advanced wifi settings they have a region setting. Choose China and tell me if it helps

Not work! Actually the lineage rom is installed and the region choosed is China. I don't know what I do.
Any solution?
Try to flash 1.9.104 st by qfil . Notice that relock bootloader . If it doesn't improve that means hardware problem .

can be a problem of incompatibility between zuk phone and wifi router as well. Some TPLink routers are already known not to be working good with ZUK Z2 Pro. So it is not always a fault of ZUK
Today i am trying sagemcom modem. No sucess! It connects for only 5 seconds.
After 4 roms(android 7.1 and 8.1), 3 routers(tp-link and Sagemcom) and 2 days, i dont know what to do!
3 months of heavy use and no problems. suddly i heppens!
But if i put the phone on the router(Very close), it keep conected, but the connection is very very very low speed.
Same problem, after stock ROM update wifi see all networks, but impossible to connect. I install zui 1.9, i update, i install persist partition, i try aex, RR... Same problem, wifi can t connect, you have solution?
Any solution?
Solution to my problem.
Sorry, i wasn't to visit here and post the fix i did to solve my problem. Anyways, here it is.
Basically i found out that the problem goes with a sudden incompatibility issue with my phone and the wifi. Im clearly not sure as to what may have caused such, but it come and goes from time to time.
Solution:
I just simply had a reset on my router and walla, solved it. Also, do a clean up on your wifi list. Forget your old SSID, and connect to the new one. This basically solved mine.
Thanks! Keep me posted and see if my solution helps.
I guess you should try the suggestion given at the comment above. But even better than that, you wouldn't have this problem if you had bought my ZUK as you initially wanted to. Cheap is not always really cheap...
