[Q] wifi drop continuously with DK28 ROM

I tried pretty much all the DK28 ROM available and I don't understand why my wifi connection keep dropping after one day usage. So the first day it would work fine. On the second day, the wifi will turn on for like 2 minutes and it automatically disconnect. No matter what I do, it refused to work properly.
I tried to re-odin the DK28 modem and it did not help also.
Anybody experience the same problem? is there a fix for this?
Thanks.

I'm having the same problem. If anyone knows the answer, it'd be very helpful!

I know this isn't technically the same thing but I had a similar issue with 4g dropping constantly no matter what rom I used. I ended up doing an odin back to stock di18 and then to dk28 extended and then finally to midnight rom. I've had zero issues since. I know its not the most elegant solution but if all else fails its worth a shot.

does anyone have any more insight on this? i ran the odexer tool, and since then, my wifi keeps disconnecting and reconnecting. not saying the tool caused this, because i have run it many times, but this problem did start right after that. i have even odined back to stock, and the wifi is still wonky. maybe some setting got jarred?? any help would be MUCH appreciated. thx

I don't think wifi sleep policy has anything to do with it.... I keep mine set to never sleep, just to save battery when I'm home. I'm not sure what Static IP is for, but once I checked it, all seemed fine; all the gateway and the rest are all empty on mine too.

kool, i hope it works for you. it's probably, hopefully, just a setting that got switched. i thought maybe i borked my hardware from all the flashing, lol, but looks like not.

Have you tried toggling airplane mode, or a reboot?

yea many times its very frustrating, i am currently in CM9 Alpha 3 and it happened this morning while i was omw to work

I haven't met this kind of case.are you sure that you are right?

yea dont take it wrong but im not a noob when it comes to this its just weird, its been happening for a while now in what ever custom rom i flash

So call Sprint tech support and have them try some steps of their own.

Dont mean to be an ass but what do you think they would solve over the phone, a Factory Reset, update my Profile and PRL, Airplane mode, ive tried all of that

I would flash a modem again, as this did fix my problem when I flashed CM9 and lost data and calls. You won't lose nothing by trying, good luck

Maybe the tower is down? Maybe they will refresh the data from their end? Customer care CAN do some nice things in trouble shooting. Use ODIN to go back to a 100% stock tar and see if it works then!

... please delete...

The issue you are experiencing happen over in the Boston area probably about 4 months ago give or take. So don't panic like I did. I had given up back then, unrooted, and took the phone back into the store telling them my wimax stop working only to find out that all of their phones are going thru the same issue. I would check with the sprint store or ask some one in your area if they are experiencing the same issue.

Me too..

I know this is an old thread but I just got the phone (used) and am having the same problem. It's *stock* JB GB27 (rooted or not) and I have not been able to get any data over 4g even if Wimax says its connected, with an IP address, Gateway, DNS address and says it's active on Sprint. And in a strong WIMAX coverage location. Ping says "host unreachable".
As soon as I turn off 4G, 3G takes over and all is good. To the OP, did you ever discover the cause?
Thanks in Advance.

Wimax sucks even when it is working. Sprint really isnt supporting wimax any longer. What is out there is all you are going to get. If you get it, great good for you. If not, oh well...

Are you using the correct modem for your carrier and Touchwiz JB 4.1.2?

That's kinda how I look at it too but I might take up the challenge to try to resolve it or play around with some custom roms now that I am rooted. Maybe go back to Gingerbread and see what happens. I actually liked Gingerbread's app drawer better.

You can try running a more updated rom, such as cm10.1 or gb27. Stay away from any 4.3 rom though, since 4g isn't supported.:good:

Thanks for the responses, so I found something odd when this happens,
I wrote down the stats the phone gave me about my connection, IP,
Gateway and DNS server. Everything checks out as belonging to sprint,
EXCEPT my IP 6.6.2.142. Well, that IP just happens to belong to the
pool of IPs allocated to the US Department of Defense Network!
(checked on a whois server)
NetRange: 6.0.0.0 - 6.255.255.255
CIDR: 6.0.0.0/8
OriginAS:
NetName: CONUS-YPG-NET
NetHandle: NET-6-0-0-0-1
Parent:

Is Sprint/Clear's servers possibly mis-assigning IPs???? This is from 2
totally different Wimax areas but I'm pretty sure that the same IP was
assigned to my phone both times.

[Q] losing wifi connectivity- full bars but all gray

so, I've read around here on the XDA forum about problems with wifi connectivity where we have full bars for wifi but they are gray and you are not getting out. many describe my situation but I've not seen any real solutions...
my problem is that I can connect to my wifi router without issue but then a random amount of time later, sometimes fairly quickly and sometimes it's hours later, I will pick up the phone and see full bars but they are gray and I'm not getting out. I can try opening a terminal window and pinging the gateway/dns servers and can't even reach the gateway.
things I have tried:
- turned off MAC filtering on the wifi AP
- switched from a 5 GHZ wifi on the AP to 2.4 GHZ net on the AP and vice versa
- manually set the phone wifi preference to one or the other (5 or 2.4)
- battery pull on the phone
- delete network settings for my AP and reconfigure
I have not yet tried a static IP config on the phone but I can easily try that... {edited to add} well, I tried static config and that didn't help at all...
one other tidbit of info, I have a work Blackberry with wifi and it never loses wifi connectivity so this is a problem unique to my Nexus.
I'm running Cyanogen 10.0.0-toro and no, I haven't tried a full wipe and reload yet.
thoughts or suggestions?

I'm not trying to threadjack here, but I just wanted to share my experiences.
I've been have the exact same thing happen to my phone (Nexus maguro). I've tried every JB rom I could find, several different kernels and my wifi eventually always goes grey on me. All network activities stop. I'm back on stock everything right now and it still happens.
It happens on my home wifi as well as work wifi.
I'm about to puttstock ICS on my phone and try that out for a couple days.
Anyway, good luck with your problems, i'm going to follow this thread in hopes you'll get a solution that may help me.
If I do figure anything out i'll post back.

seems that this is a topic that has been posted on a bit over time with no real single culprit or fix. I'll post back if I figure anything out... I know in the Cyanogen thread, I saw info that stated that the MAC address of the phone was changing and I'm going to try and determine if that is happening to mine.

I have the same issue. Sometimes even when i pick up the phone, if i look fast enough i see that the Wi-Fi bars weren't even there! Thats only 1 out of 5 times though. The other time its usually just grey bars. Sometimes it actually will click back and they'll flash to blue and grey 2-3 times and then go solid blue. Then sometimes like you, they'll stay grey. I've tried everything too...reverting to stock, Different kernels, ROMs, routers, static IP, 2.4 or 5ghz, full auto mode. The only fix that makes it a little more reliable, is using Wi-Fi PM Fast. But even that, is not reliable. I'd say its about 50% reliable then, for a huge sacrfice in battery life. For me i've noticed this started to happen with 4.2. Before that i never had a problem. All other devices though no problem. My Nexus 7 is just fine. But the galaxy nexus, no matter what router or where i am, the Wi-Fi is totally unreliable. For me, it happens within 2 minutes that it will disconnect most times. Then 1 in 10 times it'll be fine for 10 hours.
In all honesty, i've given up. Just come to deal with it. Use mobile networks when i'm not needing to download. I can download files and stream music just fine too. If there is traffic going through, it never disconnects. But when its just sitting there without traffic, it disconnects, or, loses connection to google servers i should say.

well that's not good to hear...

I installed stock 4.0.4 a couple days ago and have not had my wifi go grey on me yet.

yeah, I love Cyanogen so not willing to go back to stock... waiting for them to finish 10.1 and I guess I'll see how it behaves then.

Hi all,
Just to say that I have the same problem. I have been upgraded from ICS to 4.2 and nothing had happened but I had to downgrade to 4.1.1 (AOKP Build 4) due to other issues and after that I started notice the WiFi problem.
At first I thought it was when the screen went off, but I has happened with screen on too. I have to turn WiFi off and the back on to connect properly again, very annoying.
As I said I started noticing this after I downgraded, but then again, I had used AOKP 4.1.1 before without this issue. I think that it is time to change my phone :/

I'm on Muzzy 4.2.2 and I'm currently having the same problem. It's not a new problem since I remember having it months ago (disabled my phone's WiFi because I kept missing emails and other notifications - grew tired of dealing with it). I thought it was my router, so I swapped it with a newer one recently, but it carried forward (old router was TRENDnet Draft N and the new one is ASUS RT-N66U).
I would like to know how to properly troubleshoot this problem.

I'm glad I didnt have to create a thread for this. I have been facing this problem quite a lot. I can confirm that WiFi works absolutely fine until 4.1.2, whether it is stock or CM10 (I havent tried the other ROMs yet). I have faced this problem only from 4.2. It still exists on 4.2.2. Happens on all the ROMs I have tried till now including CM10.1 nightly as well as the stock factory image.
When the phone is sleeping, it seems to lose WiFi connectivity and when woken up, the WiFi bars is grey though it is full. If I am very lucky, it will turn blue automatically. Most of the times, I have to switch WiFi off and back on for it to connect properly.
Anyone knows the root cause for this? In case this has been discussed in any other thread?

have you posted this information over in any of the threads where the developers are working such as Cyanogen in an effort to bring this issue to the forefront for more visibility?

I have had those wifi problems with every android version and rom I had on my GNex as far as I can remember.
Sometimes it will be able to reconnect but sometimes I have to disable and re-enable wifi to get it back.
I too thought that it might have been my crappy router as I have had multiple problems with it over the years (some Linksys router).
This is really annoying because it won't receive any e-mails until I randomly decide to have a look at my phone. :/

trust me, I understand your frustration... some days, I can go almost all day without loosing wifi data throughput and other days it won't last 10 minutes without going to gray bars.
unfortunately, no one is sharing any fixes which tells me that no one has a good handle on the problem.

Same issue for me on stock Android 4.2.2. Leave WiFi on overnight and when I wake up its connected to WiFi but gray bars...

The update to 4.2.2 drivers have fixed all WiFi issues for me. For the first time since 4.1 I can now use WiFi optimization now. And WiFi is fully reliable.

same thing happened to me on toroplus sourcery 5.1, after trying everything i could think of and talking to one of the devs, i finally did a fresh download of rom and gapps. wiped cache,wiped dalvik, factory reset, wipe system, deleted android folder off of storage then installed the fresh download of rom and gapps and its been working great for me since. hope this helps.

i just know ever since moving to a 4.2.2 kernel that has the 4.2.2 drivers my wifi has been stable. I know there was a post in the anarkia thread with the ak kernel that had the drivers. but i believe most any 4.2.2 kernel would have them implemented. i do have the newest bootloader and radio too. but i know as soon add i got the 4.2.2 drivers all issues were resolved wifi wise. of course i think if you have a 4.2.2 kennel you'll have them.

[SOLVED] Data stopped working

Running CM11 on PagePlus. I cannot access the Internet. I was able to at one time. Thought it was the Rom so I flash CM10.1 and Stock rooted rom. I reactivated the phone after the installs. Every time it says the network is connected but I cannot connect to the Internet or send MMS. Starting to think it is the phone. Any ideas?

More info:
IP address is applied. Able to ping ip address but not some other known ip address. Traceroute does one hop to 66.174.216.161, which seems to be a Verizon ISP. Might try playing with apns-config.xml. I had tried the one I had when it was working previously but did not seem to change anything.

I'm new, but had similar problems

I'm not sure the MMS issue has been resolved, as of yet. Last time I check the Development thread it seemed like there wasn't yet a fix. Someone will correct me shortly if I'm mistaken, I'm sure.
The data problem you're having is one that I struggled with for a couple weeks in CM11... I don't know how much help I can be, because I'm not really sure what ended up actually fixing it for my dINC. All I know is that I spent about three hours dirty flashing and restoring from nand backups, sometimes the full backup and sometimes just partitions. I also threw in a *228 somewhere in there. Anyways, Through persistence, and sheer dumb luck, I finally have a pretty stable data connection, as long as I don't use the mode switcher in DUbattery(that seems to mess 3g up until reboot).
sometimes it helps to toggle airplane mode on then off.

Thanks for the tip. I toggled airplane mode on and off. I could then load google in the browser but it would not do anything after that. I have a new inc and an OG Evo coming in. Might have to retire my inc for the kid to play games on. My wife is using and OG Evo with no data or mms problems on 10.1 and I am sort of digging the larger screen. Also might be able to help zach with troubleshooting cm11 for the evo (supersonic).

Glad to know it was not just my phone. I am back on your 2/17 build and was worried there was some leftover firewall stuff even though I wiped everything except emmc and sd-card before the flash.
On another note. I have that other EVO coming in so should be able to load up CM11 and do some logging for you.

So I switched mobile data off this weekend with the silent profile and when I switched it back on using the default profile my data worked.

I'm glad you found a fix! On my dINC, I don't use the profiles, and mobile data crashes randomly. After flashing the March 23rd build, it has gotten somewhat better, but it always seems to skip out when I need it most... specifically.... when I use Google voice search to either dictate text messages or navigate to an address(delivery driver). the latter is especially frustrating, because I only use the navi when I'm already out of the store and can't find something, so no alternative available. Sometimes, even when the 3g symbol is full in status bar, I'll push the voice button and it will say, "cannot reach google *** etc" :crying:

[Q] Major WiFi issue out of nowhere?

Hey all. I need some advice. This morning my G3 (D850) dropped WiFi connection for no reason. It says the signal is good but the network info says saved, secured. It will attempt to connect over and over again and if it does connect the signal is weak as can be and it drops the connection within 2 seconds. My coworker has a G3 also and is connected to the same work network I am. His connection says excellent where as mine said good. His device connects just fine with full bars. I'm baffled. I've already tried manually selecting 2.4 Ghz and 5 Ghz instead of auto select and that didn't help at all. I've tried manually turning off WiFi and turning it back on. I've tried turning airplane mode on and then off to refresh the connection and that didn't help. I've done a battery pull as someone in one of the android authority forums suggested that (apparently I am not the only one having this issue.), didn't work. I've unchecked WiFi optimization - no dice. There was another post on a different forum here on XDA that said turning off WiFi and then deleting the WiFi config folder located in data/etc/wifi and then rebooting fixed the issue for them so I tried that. After reboot when I tried to turn on WiFi my G3 rebooted itself. Does it everytime. SO, I had to restore to a nandroid backup (btw I'm on rooted stock 10f) to get the phone to stop hating my WiFi toggle attempts. Last ditch effort I did a factory reset hoping for an easy fix... Nope. I don't know what else to try. It was fine yesterday all day. This morning it was perfectly fine and then randomly started having this issue. I haven't altered any system files whatsoever. I really don't want to send my device to LG for warranty replacement so I'm hoping someone can help me out that may have had this issue and resolved it. The only difference between my device and my coworkers device is he is still on 10d and I am on 10f. That could be the issue I guess but that doesn't really explain why my device has been perfectly fine until this morning and I've been on rooted 10f for weeks. I am planning on flashing back to straight bone factory stock 10d when I get home here in a few hours from work but Idk if that will help or not. Judging from the amount of google search results of "LG G3 WiFi connection problems" this seems to be an issue for several people. I won't know if it's on the software side or hardware side until I get home but in the meantime has anyone had these issues at all? People have had success in changing to Static IP but I would have to do that for every connection I attempt to connect to and that's a pain in the a$$. Also, that does nothing to identify the root cause of the issue. Any help would be greatly appreciated. =)

Thanks for the reply. So it turned out my phone just randomly decided it doesn't like my work network anymore. Idk why lol. I got home and it hooked right into WiFi. Gf's WiFi and open networks as well. I call shenanigans. I went ahead and flashed back to 10d anyway though.

I am having the same issue! But it is happening in other networks too...sometimes I get the phone to connect but it only works for a while and when I check the networks it only says Saved, even if I try to connect again

Having the same issue, whether at work or home, my wifi has become near useless. I've even gone as far as trying a different ROM. Didn't work.

Same thing here

I also have tried factory reset, installed a new ROM, changed settings in my router... but the problem remains I don't know what to do anymore, I use wifi a lot!! I searched through other topics but no one seem to know how to solve it. Unfortunately my warranty already expired, I took my phone to some technicians but honestly it didn't help at all...they all said it was a software bug and I should wait for an update but if it was just that a new ROM would fix it,right?
I am not very familiar with phone hardware but I assume that if it was a hardware problem I wouldn't be able to turn it on or connect to any network, right?? (any experts here???)
Any solution is welcomed.

anyone please?? :crying:
P.S : I tried a new baseband, new kernel and new ROMs. So far, nothing changed.
I can connect sometimes but get kicked out within minutes. At other times I only get the saved,secured message.
This is happening in every network
