LG Optimus G With Rogers Weird Wifi Problem

So I am having some wifi problems. Like most I have 5 or 6 wifis that I connect to on my phone. My issue is that I will need to use my data and my phone's wifi is stuck on trying to connect to a wifi network that is no longer available. I can't turn wifi off or anything. My only fix is to restart the phone. Any clues?

Yes. I believe I'm experiencing the same thing.
Here's my situation, I have the Rogers LGOG (Not rooted) and the reception @ work is extremely poor. So I turn on wifi to connect. I'm able to connect to my corporate wifi, but when I leave to go between floors and I'm out of my wifi range and return, I'm not able to connect. WI-FI is ON and it keeps searching for hotspots, but I'm not able to connect and the only way for it to work again is to reboot. Now, this does not happen consistently, but it has happened a few times to where I'm wondering is this a problem with the OS or is it the phone.
Any thoughts on this to point me to the right direction would be greatly appreciated. thank you.

Same problem with F180K, but there an OTA update arrived yesterday saying "Wifi bug fix".
Cant tell if they really fixed it, cause im waiting for my flight, so cant test it right now.

[Q] Wifi issues

Hey guys,
So all of a sudden, my wifi is searching and not connecting in a campus setting. My Samsung Galaxy Note 10.1 2014 is still connected to the same wifi my Note 4 was. I have tried rebooting, removing battery, shutting off and on data and wifi, and airplane mode. Nothing reconnects it. Also tried forgetting all networks since there are 5 when searching for networks it finds and reconnecting to one, still no dice. It's been 4 hours, still can't reconnect. Any ideas?

Have you tried to forget the network and then ADD it with + Add Wi-Fi network? I actually had an issue playing with a Galaxy note 10.1 2012 edition, I turned my hotspot (sprint note 4) on and named it the same as our current network (was showing how open networks aren't always the network they say and anybody can create a Starbucks-Guest network.... I used starbucks-guest because I didn't want to put my schools on here). The tablet didn't see the network even after reboots, but when I added the network manually it connected right away. Also was this connecting to the same access points or different ones on the other side of campus?

Yep tried forgetting, re-adding the wifi spot and nothing.

I've been having wifi connection issues since day one of getting this phone.
Not sure if I have the same problem.
But at least once a day, it seems the phone can no longer make a connection to my wifi.
The only solution is to either just power off the phone and restart or do what Sprint asked me to do.
Sprint said to try and reset the network connection information by dialing ##72786#
The phone will power off and then restart do some background stuff and then power off again and restart.
Once that is done, all is fine.
I've never had this happen on any other of my Android devices. I even use a static IP with my phone setup.
And yes, I have tried just using the default of DHCP.
I had thought it was my router (Asus RT-AC68U) which transmits both 2.4ghz and 5ghz. I have both setup and I try to use 5ghz the most.
I did upgrade the router software because I was one version behind, but that did not fix anything.
Also, I had a Sprint femocell in my house (provided for free from Sprint) because I had bad signal issues years ago.. But because this phone uses LTE and now it seems the phone comes with built-in WiFi Calling. (Means instead of using the cellular network it will use my network and ISP to make Sprint calls, all voice and text messages come through normally, it's basically a built-in femocell).
I returned that, whoops still in the box, need to get that mailed out fast.
I'm not sure how widespread this issue is, but I suspect it's bigger that just the two of us here. And if I'm in the wrong thread, please let m know.
Thanks
Rob

[Q] Wireless Issues with Note 4

Has anyone experienced issues with Wireless?
I will be connected to a wireless network, can disconnect and reconnect just fine, everything seems to be working, but if I open an app that is trying to load data, it does nothing, as thought I have no connection. I have tried turning it off and on, forgetting the network(s) and reconnecting and the only thing that ever fixes the issue is a restart of the phone. Once I restart it will work just fine until the next "blip" in the radio.
Thanks in advance,
Zach

Yep, I have this issue but only when connected to my WiFi extender. Connecting to the main router works fine.

Just to add info, I connect to a Samsung Verizon Extender every day since owning the Note 4 and have no issues.
I also have never had any issues like the OP mentioned. I would start looking at apps you have installed.
Remove and test and so on. I did a quick search and did not find this to be any known issue.

My issue exist on both me and my wife's note 4. Both exhibited this issue from the initial setup. It's unfortunate and annoying. If it weren't for the camera and s-pen I would've already gone back to my M8.

I found this, maybe it will work, sorry you are having troubles.
Problem: Wi-Fi connection
Every time a new smartphone is released there are a lot of reports about problems with connecting to Wi-Fi networks or maintaining good Wi-Fi speeds. Here’s what to try if it happens to you:
Potential solutions:
Try turning your Note 4 and your router off for a couple of minutes. Now turn them on again and retry the connection.
Take a look in Settings > Power saving and make sure that low battery life isn’t restricting your Wi-Fi.
Try forgetting the connection, choose your router in Settings > Wi-Fi and Forget. Enter the details again.
Try the free Wi-Fi Analyzer app and see if the channel you’re using is crowded. Change to another channel if it is.
Take a look at the settings on your router. Make sure that MAC filtering isn’t on, or add your Note 4’s MAC address, which you’ll find in Wi-Fi > Settings > Advanced.
Make sure that your router firmware is fully up to date.

None of these work. Restarting the phone always works.

Thanks. Funny you should post this, I read it right after I posted here and was planning to check out the MAC filtering when I get home. Weird thing is this: My phone connects to the main router fine, with zero issues of any kind. We have a WiFi-extender by NetGear. My phone will connect to it, but will not exchange any data. My computers, HTC One, and my wife's old S5 all connected to the extender fine. Now, neither of our N4's will properly connect to it. It certainly doesn't seem like an issue with the extender, but that's not to say it isn't possible, and I sure hope that it is and not an inherent problem with the phone. Will try some troubleshooting tonight and report back.

I've run into an issue with the wifi since getting my Note 4 last Friday. The problem I am having is it will connect to my wifi network without any issues, but after a while (it could be 2~8 hours) my note4 will lose it's connection to the wifi router and not be able re-connect until I reboot the phone. I have a dual band ASUS router with the latest firmware, when the note4 craps on itself with the wifi, the wirelessG connection will keep asking for the password and come up with "authentication error" and the wirelessN connection will come up with "unable to obtain ip address"
When the note 4 has this issue, my router log shows "Dec 9 16:54:28 kernel: eth1: received packet with own address as source address", checking further into the logs on the router, this didn't start popping up until I got the note 4. I am hoping it is a software issue, Verizon did however confirm that there is an update coming out the the next few days to address a wifi performance issue...
I have other wireless devices that use both wireless G & N and don't have any issues, i've rebooted the router a few times even though that is not the problem. I even hooked up a different router to see if that would help, but the same problem is still there.
After playing around with different settings, I have yet to find a solution to this problem. Verizon support has me running the phone in safe mode to see if it's an app causing the problem.....

Are you by any chance using 5 GHz on your router? I am having issues with 5 GHz connections and no issues with 2.5.

Nexus 5X can't find any wifi network

So I bought a Nexus 5X 2 days ago. When I first started the phone it was running Android 6.0.0 and it didn't have issues. But a update for 6.0.1 showed up and I downloaded it. And then the issues came. It cannot find any wifi network... The problem isn't from my network, because every other device finds my home network and all the neighbors network, but the 5X doesn't find any... I tried factory reset, network reset, cache reset, nothing helped. I even tried Android N beta and for a moment it fixed the issue, but this morning the wifi problem occurred again. I sign out from the N beta and through Mobile network it managed to download the last stable version(that's what google is calling it) - 6.0.1 and the problem was still there.. after some restarts of the phone and some factory resets, i thought the problem was gone, because it managed to find every wifi network in the area, but after i used the phone for 25-30 minutes, the wifi problem occurred again and ever since... So, is this a common issue with the phone, or the android 6.0.1, or is my phone a defected one? Should I go to the store and ask for a replacement? Or will the next phone do the same thing ?

Hi something similar happened to my 5X (6.0.1). It was able to find wifi network but I was not able to use internet even-though internet was working for other devices. I have restarted phone but my phone stuck in to WIFI Obtaining IP address...
I have restarted my router and problem resolved. Happened two times. Might be some bug in software.

I'm currently facing this very same issue, no WIFI networks are showing up. I've already flashed latest N preview with same results, funny thing is that this morning was working just fine. But I had to reboot the phone and now it won't detect any WIFI Network at all.
I'm starting to think I have a failed unit, but since I'm outside the "US" I can't send it back for warranty repair. So I'll just keep it and keep restarting until it's fixed again. This is really frustrating, never happened to me with any device I owned before.

Is it every wifi or just your wifi?
If it is just your wifi, try factory resetting your router after recording the settings, or try removing some entries that my be using NVRAM.
I've seen cases where the router runs out of NVRAM to record the DHCP entries and that causes connection issues. It doesn't show up for other devicdes because their entries are already stored in NVRAM. It is just the incremental new device you add that triggers the problem, so you naturally think the problem is with the new device since all your other devices work with the router.

my solution for wifi not found/working
i´ve upgraded from the nexus 5 to 5x.
i had a really weird issue with my wifi.
only found my wifi when i was not in airplanemode. so i read 1000 of articles about the wifi of the n5x.
just the standard blabla. so i did my own research
while my n5 and my n7 + 2 laptops had never issues my new 5x didnt find my wifi. i really thought it was an hw-issue. but it wasnt.
i am using a fritzbox router. newest update, made a reboot, rebooted phone. nothing happened.
then i checked my wifi channels, set it to manually and instantly found my wifi. i really never expected that the channel got such a big influence. may be the latest update brought a bug for the wifi channels or the hw is just not capable of some channels, dunno. but this is what helped me and it was nowhere mentioned in any forum.
tl;dr
try to change your wifi channel of the router.
edit: btw i found the 5ghz while the 2,4ghz wifi didnt work. but i wanted the 2,4ghz wifi to work because of the short range of my 5ghz wifi.
atm i am on channel 8 and i got no problems with the 2,4ghz wifi network

I don't know about Europe, but usually in the US we only use channels 1,6,11 to prevent overlap.
This is because there is overlap in the channels so you can't really use the in between channels due to too much interference. If you are the only wifi transmission in your area it is fine to use any channel, but if there are others and they are using standard channels for no overlap/interference and you are using in-between channels, your signals are probably going to interfere with each other.
When everyone is using the set channels, then they can negotiate properly and everything works better. With overlapping frequency bands, the negotiation doesn't work well because your signal sometimes looks like noise to the other device.

Hi, thanks for your help but unfortunately it's every wifi... it just hangs on "Searching for Wi-Fi Network..." and stays there...
I already talked with LG and they asked me to send the unit for repair, but I'm no in the US anymore (I was for a short time of period and that's when I bought this phone). So that would not be an option, right now I'm only using 4G and trying to measure it, lol
Just another question, do you guys think I could use a WIFI external dongle through USB OTG? Could that be possible on the Nexus 5X?
Thanks for your help! :good::good:

Hi, thanks for the suggestion but the problem I'm facing it's with every wifi network around, not only mine.
I guess unit is defective, but could a simple reboot trigger this kind of behavior? This is strange, never happened on any device I've owned before. :crying:

WiFi issues: can't connect to any network anymore [T800]

In the last 6 months or so I have been experiencing frequent wifi issues, regardless of the custom ROM I'm using. Usually some time after a new installation I am unable to connect to the networks I normally use (my home network and the one at work which uses a proxy server). No matter what I do (clear cache, factory reset, change ROM...) the problem persists. In settings a number of random messages are given: secured, disabled, authentication problem, etc. Every now and then I can get a connection (never at work though) but it doesn't last long. Any help for troubleshooting this would be appreciated. I hope it isn't hardware failure since I'm still enjoyng this tablet after all these years!

Mine started having wifi issues off and on a couple of weeks ago. The wifi started to not turn back on after waking it up, at first just in manually turning it off and then back on seemed to work. Last Friday it just wouldn't stay on at all. I would go to the wifi in settings, it sometimes would get stuck saying turning on. I finally did a factory reset on it, it at first seemed to fix the problem, even spent a couple of hours trying to get everything set back up. Then the problem returned, it just keeps turning the wifi off, if i can even get it to turn on at all. I was going to try and use my phone as a hotspot through Bluetooth (not sure if i can or jot, never tried before), but even the Bluetooth won't stay on. So Sunday, after spending way to many hours fighting with it, i went out and got a new tablet.

Have you tried using the Samsung Kies app to flash the latest stock rom, Dont use Odin or other non Samsung approved flashing software.
I have had my T800 for over 4 years and had no real problem with the wifi connection, But i have heard that there can be compatibility problems with some wifi routers, Also try changing the channel number on your router, Auto channel was giving me poor connection on my PC, I ran the inSSIDer wifi app and it said to manually change my wifi channel to channel 1 the clearest channel as other wifi and bluetooth and wifi dongle even you smart gas/electric can cause interference., auto was picking channel 13 for some reason and it fixed my problem.

Thanks, but since it's the router at my workplace there's not much I can do on that side. Question is, are there any specific steps I can take to verify if it's software-related or if the wifi module is just gone?

Wifi and Bluetooth both use the 2.4ghz frequency, So they can interferer with each other and can cause constant disconnect`s, I have seen this many time, Use 5.0ghz on your T800 if you can, Or disable Bluetooth.
Does your wifi work OK on other brands of router?, Or is it just the one you are using at work.
John.

It's kind of tricky to answer: let's say the times this issue appeared it always stareted at work, but then also at home I couldn't keep a stable connection. Once the problem starts, I get no connection at work at all and very difficult connection at home (meaning it does connect intermittently).

UPDATE. After other attempts and a complete restore of stock firmware, I have both wifi and bluetooth not working, constantly "turning on...." but never activating.
