Optimus L9 Wi-Fi problem . - LG Optimus L9 P760, P765, P768, P769

I have an LG Optimus L9 P765 (Indian variant) with Stock ROM v10d on it.
WiFi on my set seems to be misbehaving. It connects to my network and works fine for sometime, but when I leave it unused for about say 5 minutes the mobile does not connects with my WiFi network.
In notification bar it shows that it is connected but actually there is no data transfer occurring.
Its very irritating as I don't get instant emails, whatsapp chats etc.
Is anybody else facing the same problem ? Please suggest any remedy for this problem.

Yeah, same problem here.
I've got an Indian P765 with V10d stock ROM as well. If left idle for sometime, the wi-fi seems to be connected but no data transfer occurs.
The small upward pointing triangle is shown on the wi-fi icon in the notification area, but the data transfer LED of the wi-fi modem doesn't blink, and so no webpage loads.
But if the wi-fi is being used continously, the problem doesn't occur.
Looking forward to a solution, thanks.
Edit: Reduced the Beacon Interval of the Wi-Fi modem to 100ms. The data connection is maintained now.
Problem solved. The phone's working fine afterall.

Before that happens go into wifi settings press the menu button hot advanced and turn the wifi sleeping policy off that is all that I can suggest

Beacon Interval of my WiFi modem is already 100ms.
Problem still persists.
Any solution anybody.
The only solution for now is to change WiFi sleep policy to Never instead of Always in WiFi settings.
But that turns on Mobile data or 3G (which ever you have) which is more battery consuming.
And there's no point of keeping a smartphone offline by disabling either WiFi or Mobile data.

P769BK has a different wifi issue. All 6 of mine have had this same issue.
Enable wifi and use if for a few hours.If wifi router looses internet access and you try to download an MMS it fails.
Disable wifi and try downloading MMS via cellular network it fails. Airplane mode toggle does not work.
A reboot is required to fix this. Very irritating when connected to a wifi network that has a bad connection.
Don't even get me started with wifi-calling. It just plain sucks on 4.x ROMs.

I use WidgetSoid which gives WIFI and 3G icon (also called power switches) on Home Screen and reconnecting is just a HALF SECOND deal for me. Its even quickly re-connectable from WiFi PowerSwitch in Notification Panel.
By the way, I did not notice this issue on my P765 (india) L9. Works well with Vodafone Mumbai 3G, and WiFi always connected even after idle time upto 2 hours mostly at home. Like they always say, results may vary.

Problem: WiFi is not useable
Hey Guys,
i've got a huge problem. I can't switch my WiFi on. The problem exists since a few months and I've tried to fix that by myself but my knowledge about programming is quite small. Please help me. WiFi is one of the most important functions. Is sendng it to LG-Support the only way to get that fixed?
Pls Pls Pls HELP ME!

hi friend,
You already managed to solve your problem?. I have a similar problem, did the bootload and installed cyanongenmod 10.2 for P760 and everything worked perfectly, after I turn off my smartphone realized I was not connecting the wifi and even tapping the power button it does not turn on, put your smartphone in order factory original and still the problem continues.
Can someone help me?

WiFi issue on my Hero...

Hello everybody!
Someone of you has noticed a poor WiFi reception on Hero?
I'm experiencing a poor WiFi reception in my house when Hero is connect to internet thru an access point.
What happen is that after WiFi connection has been established the phone tends to loose it and restart connection thru GSM/3G link.
That happen also if phone stay in the same place without moving around and also when phone is close to access point location.
Any idea about way to solve the problem?
Regards.

Just an upgrade on issue...
If I turn off data connection thru GSM/3G and switch on WiFi seem that WiFi connection is stable so maybe issue come when both data connection are enabled...
Anyway is annoying shout down each time data connection on GSM/3D and power on WiFi!
Regards.
i believe wifi goes idle when not in use. so it connect to 3g or edge. However there is an app if not various in the market already to help keep wifi always on..
Do a search for wifi and see for yourself.

Thanks for suggestion!
At now I've solved turning off GSM/3G data connection when I'm at home anyway I guess that WiFi reception sometimes go away due to issue of the phone or maybe as way to save battery...
when that happen phone stay unconnected so I guess that should be better if I will check for apps that keep WiFi connection always working!
Alex
when the device goes into standby, the wifi is turned off to save battery poweer, and it will go back to 3G.
go into the wifi settings, press menu and select advanced.
select the timeout options
set to never and it will not turn off when in standby.
problem solved and you shouldn't have to turn off Mobile data, although with the settings widget on your homescreen turning mobile data off off each time is hardly going to ruin your life. in fact i tend to do this anyway, just cos i have spent too many years with windows mobile....
Here's an annoying bug I've found tho - on TMob UK
If I send an MMS from home, wifi on, it sits there, and doesn't send the message. Until I turn off wifi and 3G kicks in again.
Now I know for a fact that on my Magic, it was able to turn on 3g/HSPDA to send the message all by itself. Might have a look in thodse advanced settings tho to see if there is something I can do.. Not a biggie, just a bit of an annoyance.

I too, have been doing a search on Forums all over Google looking for a resolution to this.
I have noticed if Wi-Fi is enabled I am unable to send or receive MMS messages.
It is an annoyance having to turn Wi-Fi off each time also I am never to know if someone has tried to send a message in the first place.
Currently using T-Mobile G2 (rooted with MCR Rom 2.8) on T-Mobile UK

[Q] wifi issue

My wifi connection often wrong, always in after a period of using, have no access to the Internet. Every time the wifi turned off to open another can get to the Internet, can wifi signal is always full. I searched a lot of method to did not solve, including XDA * # # 0011 turn off on wifi power save mode, when problem solving, but after a while just the same. And with only G mode and so on route, are not solutions. Change a lot of Rom, the kernel baseband all not line.Who's a way to solve?
I am not sure if this is the case but - have you tried different router? My S3 for example has issues when I go to my friend's house (he has some old/er Belkin router). However, when I am home wifi is blazing fast and no issues what so ever (cisco e3000).
my phone has a slight different problem, the phone detects strong signal for all my wifi, but will only save it, and not connect right away, some will not even connect, and sometime the speed is very slow.

I am sure there is no porblem with the router,SGS2 and IP4s with the same router is fine.
I'm getting WIFI problems when waking from deep sleep. My settings are set to keep WIFI on when sleeping only when plugged in, as i find this extends my battery life a little more.
Sometimes it reconnects when waking up, and other times it doesn't and i have to turn WIFI off and then on again to force it to scan and reconnect. If i don't do this and check WIFI, it says it's scanning, but never finds or connects to a network.
Anyone else get this?! I read somewhere about sleep of death on GS2?
There is a known problem with the wifi, I have just changed my phone and so far evrything is working.
been through 9-10 phone with different problems.
Ok, i've tried turning off WIFI power save in the system settings *#0011#
I'll report back with my findings in terms of waking from sleep and possible additional battery drain...
Turning off powersave didn't help on my speeds tho. My SGS2 can pull around 5-600KBs a second, while my SGS3 only pulls roughly half despite being at the roughly same location (ie laying next to each other)

Problem with cm9 and wifi

Hi i went from stock ics on my ray to cm9 by followingnexact step by step guide provided by cm9. Used their kernel as well. Have never modded my phone before. Having a small problem with wifi though. After my phone has been asleep for a while, if i wake it up the wifi icon in status bar is no longer blue its a dark grey and i can no longer browse anything or use the internet. Ive tried rebooting. I did the whole wipe cache etc when installing cm9. In wifi settings in advanced ive also left the setting to "leave wifi on when sleep" checked. If i turn off and on the wifi connection the phone ofcourse is able to reconnect again the icon is blue and i can connect. It not jsut a one off thing its been happening since i isntalled the rom.
If i wakek from sleep a few minutes later i have no issue with wifi. Its only when its been sleep for a while do i have this issue.
Any solutions?
I have the exact same problem but for me it's even bigger, whenever i turn on wifi on my modem, i can connect to internet on my phone, but after awhile i lose my connection completely, on my phone and on my pc also, the only way to get it back is to reset my router and wait for like 5-10minutes...

If its also an issue with your. Pc then your issue might be also the router.
My other devices actually work fine in my case its oky this phone that has issues. Macbook iphone ipad nexus s no problems with those.
Same issue here. I can see available networks but unable to connect. There should be no problem with the wifi router as all my other devices work well and I have tried another router. Now I have to flash back to stock firmware.

Your issue seems more severe than mine. Mine actually connects and works, just that when it wakes from long sleep it wont work until i turn off and on wifi.
I get this problem too, but my problem even worse than yours. My wifi lose it's connection after a while, but the icon on status bar shows it's connected, running ping test, browse, even play store can't be accessed. I pinged the router and got unreachable.
And yeah, this problem occurs when I'm using all ICS based rom..
Anybody has any idea if this is a known problem, or if its just us few having thisissue?

I have same problem. I have SE xperia mini with CM9. WiFi worked fine until yesterday. Now phone can't connect to AP (full signal - try connect -> signal drops down), but sharing 3G internet over WiFi works fine. I cleared dalvik cache, but that didn't help.

xperia u and wifi

sorry for my poor english
I have a xperia u no brand no root or anything. I found out that when the phone is connected through wifi - my own domestic line - and goes to deep sleep, after a while - i cannot be more precise since it is never the same amount of time - it loses the connection. It appears to be still connected, since the wifi symbol is still displayed, but cannot receive or send any data. I therefore have to turn off wifi, wait for a couple of minutes, and turn it on again. During this "wifi-sleep" the phone is not aware that is not getting any data, so it won't let 3g take over. I've tried many solutions - change wifi channel, change wifi beacon - but nothing seems to work. Of course I've already set the phone not to drop connection when standby in the wifi menu. the only trick that seems to work is to use apps such as regpon wifi that keep the connection artificially "awake", but this is definitely not a solution since battery drain skyrockets.
thank you in advance

Strange N-router Wifi problem 4.4.2

Hi guys,
Looked for an answer on this forum, no luck....
Problem,
When connected to an Wifi N-router, my wifi works for an certan amount of time and than drops. Wifi says I have a full conncetion but all my apps say there is no internet. Manually set Wifi on and off works until the connection drops again.
The strange thing is that it is only on N-routers. When I put the mixed mode on, it works like a charm.
But the problem is, Wifi is so slow on mixed that it is no option for long term.
Also it looks like even some routers with mixed on, makes the wifi drop. On my ubee modem every mode drops the signal, on a older linksys modem mixed (b/g/n) works.
Solutions tried:
- Got a new phone, same problem
- Factory reset, same problem
- Disabling Wifi power saver or any battery saver, same problem
- Change Wifi direct name, no luck
- Try apps like wifi repair, or signal boost, no change
- Static Ip adress, did not work
- WPA, WPA2, WEP, no luck.
- disable sleep on my phone, no luck
- Reset the modem, even factory reset the modem, same problem
- Problem was still existing after Firmware update....
I think I tried almost everything. Do one of you have the solution?
Phone
Acer E700
Kitkat 4.4.2
Not rooted or anything...
Thanks so much!

The issue was driving me crazy since the update to KK 4.4.2. It was like disconnecting the Wifi but the Wifi was not disabled, just the Wifi icon turned grey instead of the green when you are actually connected. Well long story short, turn off your BLUETOOTH and it will not disconnect anymore from Wifi. It seems to be a 4.4.2 bug.
Yeah I know.. who would have thought that?
Anyways, this works for my Acer E700 for days now and I am pretty convinced it will keep on working. Before this I was losing the connection within half an hour (but when on the power adapter the Wifi wasnt dropped)
