G2x wifi problem

My wifi connection is not very stable. Keeps on disconnecting.
I heard this is a known problem for theb g2x. Are any of u experiencing this issue? And or know how to fix this?
Is tmobile gonna do an update fix for this?

I've experienced wifi issues myself. Wifi was working flawlessly the first week i had the phone but now it seems as though it does not want to connect to any network -__- it just says 'error'
Not sure if i had something to do with it acting up, maybe i downloaded an app that caused it to act up.. idk
No definite word if the upcoming gb update will fix this issue but i sure hope it will!

sometimes simply rebooting your router can fix this. of all the wifi threads i've seen, i never saw anyone mention this. but like i said, it will sometimes fix it.

After leaving my phone idle for 15+ minutes, I'll lose wifi. Simple fix is to disable/enable wifi. LG knows of this problem and will release a fix on the next update. http://www.lgforum.com/forum/boards/general/lg/topics/g2x-wifi-problems
Now others are having a different type of wifi issue where it won't connect at all, I'm not sure if it's a hardware or software issue.

I'm having the exact same issue. Wifi will be connected, then after a period of time the connection gets disabled. It's quite annoying, as I often do not notice it for a while, after I have already gobbled up a bunch of 4G bandwidth.

I fixed this problem with G2xFixWi-Fi from the market.
Just 4 clicks and it is done.

two separate wifi problems with the g2x
it's good that your wifi problem was fixed with the G2xFixWi-Fi app. but that only fixes the dns problem.
there is another wifi problem where if the phone is in idle for a while and you wake it up, you see from the indicators at top there is no wifi icon and that it is trying to connect 4g but doesn't succeed. the 4g icon flashes on briefly and disappears. it keeps on doing this every second until i manually turn off wifi. then it connects to 4g. from what i can deduce, if i don't turn off wifi before putting it in idle, it does this as well after the phone is in idle for a while. i'm not sure how long after the screen switches off that this looping process happens, but give it 2 hours and i feel that the back of the phone is really warm. i'm thinking that it's warm because it is constantly in this loop. this may also be the source of the massive battery drain that some are seeing.
if i manually turn off wifi before putting it in idle, this doesn't happen. so that's my solution for the time being. i heard about using tasker to automote toggling wifi on/off as the screen is on/off. and it seemed to work at first. but after an overnight test, i found out that the phone response time is sluggish and unpredictable, to the point where i had to have perfect timing just to unlock the phone from idle. rebooting the phone didn't resolve the sluggish response problem, but uninstalling tasker did the trick. so now, it's back to manually turning off wifi before putting it in idle.
another solution proposed is to set wifi to never sleep in the settings. the last time i tried it, it didn't work for me. but i'll try it again to see if it'll work this time.

setting wifi to never sleep did not help
nope. i changed my wifi settings to never sleep and the wifi disconnection problem still happens.

When my phone was stock I had problems with Wi-Fi when it was simultaneously trying to run 2G or 4G. Since then I have switched to various ROMs and Wi-Fi is rock solid. I do use Juice Defender which turns it on and off when screen is off and I'm not running a short list of programs like Pandora. It also reliably switches on when I arrive home.

My G2X won't connect to every WiFi network, and there are a few it cannot even find. I was in a cafe the other day and my friend's laptop and Nokia connected to its WiFi network and my G2X could not even find it... (( So, the problem is, some networks it recognizes but does not connect to (it sticks to "obtaining internet IP..." and then disconnects) and some it cannot even recognize. But to most networks it connects no problem (my home included)... What could be the problem? Can anyone help me?

If you have not messed with the ROM and are having this problem - try TMo tech support first, then ask for a replacement if not fixed.
I have had excellent WiFi performance with stock ROM and EB Froyo's and GB (with and without kernels) - WiFi always worked OK. Could be bad unit - it should work!

My wifi has worked flawlessly, but I think it may depend on the router. I recently bought a wifi repeater to use on the other side of my house and when I connect to that, the G2x will disconnect from wifi after about 15 minutes of idle time, like previous posts have said. I switch back to my regular router and it never disconnects.

I have also notice the problem to.

I am experiencing this same issue. My phone is rooted with no roms. This just started happening within the last week. Does anyone know of a fix for this yet besides possibly factory resetting?

This sounds like normal behavior honestly. What is your wifi sleep policy set to? By default the wifi radio turns off when the screen is turned off and then turns back on when the screen turns on.
G2X CM7

Thanks for responding. I have it set to "when screen turns off." The weird thing is I never noticed it do the little switcheroo before. Also, I have Juice Plotter just for fun and it used to show wifi for most of the night when I'm sleeping and the phone is charging. And now it shows APN during that time. I guess it was messing up before and now it's doing what it's supposed to.
Can you enlighten me on a myth, I heard that the wifi consumes less power than the APN or 4G. Is this true or false?
Thanks again

With a LTE or Wimax phone, I think so. With a phone using hspa+, I don't think so.

Did you try.
Did you set it like I do, WI-FI never sleep. Because where I live
T-MOBIL had no cell service. Well, Very spotty coverage.
Also check how many people in you're neighborhood are on your same channel. And change yours.
Look in mark there's a free APP that's a WI-FI analyzer.
And change to one

My wifi is acting weird. It does a loop whenever i have a WPA/WPA2 settings on my home wifi but works when i have it disabled. :S It was alright with stock froyo and stock GB i uploaded from LG. then i flashed Xboarders OTA 1.2.2 GB and this happens.
Can any1 give an insight how to fix this ? =(

im having the same problem, i bought the g2x the day it came out (when it had froyo before gingerbread came out) and never had a problem leaving my wifi on 24/7 it wasnt until the update for gingerbread came out that this problem started happening, it really sucks for me since im using my g2x as an AT&T phone for now all i get is 2g speeds
---------- Post added at 04:43 AM ---------- Previous post was at 04:35 AM ----------
also something i tried and worked was turn wifi off, turn off your phone and turn it back on then go to menu>settings> wireless & network>wi-fi settings>check connect to wifi and check connect to wifi that worked for me (holding the phone in landscape mode (horizontally) ) i add that in because one time i was turing the wifi on in that order it didnt work i dropped my phone and picked it back up in landscape mode and wifi was connected. im not sure if anything i said helped anyone at all but hope i didnt waste anyones time

[SOLVED?] WiFi and Deep Sleep

Ok, so I think I've figured out why my SR wouldn't go into Deep Sleep when WiFi is on. I think it stems from fact that there's a lot of multicast traffic (IPTV) on my network. I'm a U-Verse subscriber with fiber to the home (FTTH) and my entire house is connected via Ethernet, including the set to boxes (STB). No coax whatsoever is connected. As a result, my STBs share the same network as my non-STB devices (WiFI, Servers, PCs, etc). This causes the STB IPTV traffic to flood the network including the WiFi (my theory). I decided to test my theory by moving all my WiFi APs (3 of them) to a separate subnet, thereby eliminating multicast completely from the WiFi. And what do you know?...my SR goes into Deep Sleep when WiFi is on.
Hope this helps others with the same problem. Switches that are more intelligent can help with the filter multicast more dynamically. Look for something that is IGMP aware and that should help.

How did you get FTTH with U-Verse? It is typically FTTN.

I think it depends on your area. My friend lives in a brand new house about .25 miles from me and he has FTTH, while I can't even get FTTN because my neighborhood is 15 or so years old.

Some wi-fi routers are better than others for this issue.

I've attached a betterbattery screenshot of the wifi related kernel wakelocks I get. This is supposedly from the wi-fi router saying "are you there, are you there, are you there".
This thread talks about the issue and even recommends a router model that does not cause the problem.

The wakelock described in that article was essentially my theory, but for multicast. I noticed the lights on my APs blinking like crazy. I'm using the exact same three APs, just now separated by a router. I'm running DDWRT on three different types of APs as well (Netgear WNDR3300, Netgeard WNDR3400, and Linksys E2000).
As for FTTH, yes...there is a single strand of fiber going into an Alcatel-Lucent NID and then Cat5 to a 2Wire gateway that feeds the Ethernet to the rest of the house. Pretty killer setup. I've got GigE everywhere with 2 ports per room...even in the garage.

Heh, nice. I've got FTTN, but the VRAD is like, less then 100 feet away, so they can easily provide me with higher then promised speeds (I have the 24/3 plan, I get 26/4).

Good to know they are finally doing that. Maybe eventually they can compete with FIOS on speed. Gotta love 44 down and 35 up.

I think my skyrocket is just defective
Well this doesn't appear to be the problem with my Skyrocket. I got home, took it to my friends house and connected to his wifi. (Not Uverse) Phone spent 95% of the time awake and 5% in deep sleep, and it was just sitting on the couch next to me with the screen off, I never touched it. So then I tethered it to my Galaxy Nexus, and the exact same thing happens. I thought maybe this would be the case, as my Galaxy Nexus has no issues going into deep sleep at home on my Uverse wifi setup. I really believe now that there is some defect in this phone, and will be returning it to AT&T for a new one. Or some other phone even.

I have this same problem on my FIOS home wifi. Plagued me for weeks. Looked for solutions, tried everything. The router just sends out too many ARP requests, which constantly wake the phone. Even on boneStocketeer with background sync disabled and no apps installed, not even signed in Google account, I'd still get like 15% wake locks from wlan. I've given up at this point I've tried everything on that router. And since ARP doesn't have a port, I can't block them.
If I set up a separate AP connected to my router with dd-wrt, I could filter multi cast stuff like that?

Wouldn't a simple solution to fix the wake lock caused by wifi be to change the wifi sleep settings so that the phone turns off wifi when the screen is also off?

Well yes, that is what I'm currently doing, but LTE is much more of a battery hog than Wifi. So I get about 12 hours on battery, with fairly light to maybe moderate usage, but better than nothing I guess. It is frustrating because otherwise this phone is just absolutely great. Super fast, and LTE is amazing here in Houston. I will get this figured out eventually.

I can get up to 17 hours with moderate use, I usually leave LTE on all day, and it is a huge drain when the screen is on. But it is better than nothing, better than what I was getting on my Inspire. I think the Wifi also has more to do with the ROM you use, when I was on stock I got better battery life when I used Wifi all day, rather than leave it off and have LTE on.

Well my skyrocket wouldn't take the update that I guess came out just a few days ago (probably because it was root and had CWM on it) but whatever. I was FED UP with this thing. So I downloaded the UCLA rooted ROM and Modem and wiped the whole blasted phone. Factory reset/wipe data, Formatted /system, wiped cache and Dalvik. There was nothing on the phone (except the internal and external SD card where my titanium and nandroid backups were at. Flashed that ROM and Modem. Set up phone, restored JUST my downloaded apps like games, etc. Froze AT&T bloat.
And I no longer have the sleep issue.

I solved restarting my router.
AUs

I just got this issue too.
Tracked it back to SX Virtual server and Dropbox, and now the wakelocks seems to be gone.
What I did was this:
Tried Shark - it showed that there was a lot of packets sent to and from local computers on my network. Nothing more useful info from that.
Tried Network Log, it showed the amounts of packets sent and receieved by Kernel. And most of them was sent to/from local computers, using specific UDP ports.
Used TCPview on the computers to see what it was. It informed that the ports was used by two programs: SX Virtual Server (identical to D-Link Shareport) and Dropbox.
I uninstalled SX Virtual Server/Shareport (it's useless anyway) and disabled Lan sync in Dropbox.
Now, the Kernel network activity is almost idle.
Hope this helps others with this issue.

I know what "Best wifi performance" does

At least one of the things it does is stop the phone going into the deep sleep. Based on CPU spy my phone had no deep sleep at all. When I turn it off my phone started going to deep sleep.
Not using that feature again. Good to know. Try it yourself.

This may in fact be the issue I have been having. After around an hour or so (seemed to vary) the WiFi seemed to stop working. The WiFi symbol was still there and even doing a ipconfig check all the "numbers" came back correct yet there really was no connection.
I am going to give this a try and really hope it works. This issue has had me contemplating returning the phone, which I really don't want to do.
Funny thing is, if this works it was not part of the solution that HTC recomended me trying to fix the problem.

Maybe this is connected to the push notification problems that the phones are having while on WiFi.

I had that option checked and I noticed my battery life sucked. When checking usage I saw "Android OS" had used 25%. I turned it off and it dropped to 5% or less

After turning this on last night I have not had to "toggle" the WiFi on and off like I had to do before. I am not quite convinced this fixed the issue but it seems to have a shot.
Only weird thing is after leaving WiFi on all night I checked the battery status to see what was using it and there was a large gap of the WiFi not using any battery but again I never had to toggle so I guess I am not sure what that means. Was the WiFi off during that time and I would have received no emails etc... Or was it really connected.
I am wondering if any of this may also have to do with my router. My previous phone would also loose connection to WiFi but no where near as often. However my other devices using WiFi (PS3, GoogleTV, TV. etc..) have never had an issue of loosing connection. So I am sticking to it is the phones fault

[Q] "other" WiFi issue??

Ok so it seems many people have some complaints about the WiFi on the One X but from what I have found, no one has the same problem as me.
When using WiFi after around an hour or so (seems to vary) of not being used the WiFi seems to loose connection, but it still says its connected and the only way you can tell it really isn't working is by trying to use the net in some way.
I turned on the "best WiFi performance" option and that seemed to stop the connection loss but really eats up the battery. So that is not a full time option.
I wonder if i should be taking this phone back and exchanging it (once they leave customs)
I also have an issue where when I put the phone in the car dock (unfortunately not the nice one that connects with the back contacts like I thought I had ordered but one that uses USB) when I take it out my lock screen no longer shows the weather when you hit the power button, I have to go back into the personalize settings and change it to another lock screen and then change it back.
Some detail: when connection is lost the phone is sitting in the same spot which is only about 3 feet away from the router. My previous TC Aria running CM7 would also lose connection occasionally but it was no where near as often as this. I thought that maybe it was my router seeing that its an old Linksys WRT54G Ver2 but no other devices that use WiFi have this issue. I updated to the leaked 1.82?? version but I still have all the same problems.
Anyone else have this issue? Think I should exchange?

5.1 Battery Issues and Wi-Fi Router

First off, I’d like to start by saying I believe, overall, battery life on the N5 with 5.1 is better than 5.0. However, after upgrading, whenever I was home I noticed extremely poor battery life—and the built-in near useless battery monitor didn’t reflect anything interesting. Thinking it might be related to the poor cell signal I have at home, or my Wi-Fi connection—because I didn’t have the issue when I was not on Wi-Fi at home—I upgraded the firmware in my wireless access point at home and the problem just went away. Instantly battery life was back to normal.
Hope this helps someone else!
Cheers.

I'm curious what kind of router you have? Router reboot probably would have resolved it for a while. Doesn't matter though, battery life still sucks since 5.x.

Technically my router doesn’t apply here, but most people have a router that also does Wi-Fi. I use an enterprise-class wireless access point at home from Ruckus Wireless and, while possible, rebooting enterprise-class devices tends not to change much.

Had you searched a bit you would've found some older threads from 4.4.2-4.4.4 where people discussed certain network traffic causing weird wakelocks on their phones. Given that 5.x is still new we're not seeing a lot of talk about this yet and it can't be certain whether it's the same issue.
This could also be a factor of settings you have. Wifi optimization, scan while sleeping, avoid poor connections, etc. These are variables that need to be accounted for.
That said, the best test for you right now is to run some controlled tests.
Before you go to bed, reboot your phone, note the battery level, and leave wifi enabled. Note battery level when you wake up and about how much was lost per hour of sleep.
Next night, do the same. Reboot phone, but turn wifi off this time. Note amount lost per hour in the morning.
This determines if wifi is the culprit. If it is, turn on AP isolation on the router (wireless devices can't see/talk to each other), reboot phone, enable wifi, note amount lost per hour. If AP isolation fixes the issue, then it's the weird traffic wifi wakelocks we saw in the past.
I'm still on 4.4.4 because **** lollipop and it's issues, and because my phone works fine without any weird crazy battery loss. If it ain't broke, don't fix it. So I can't really test for you.
But you need to start testing, controlling for variables, and recording results if you want to narrow down the problem.
