So I have this tablet here at work that one of the staff told me was "broken". Upon checking it out I realized that what she meant was, it simply won't connect to WiFi. I hard reset it, set it back up as normal, and during setup it wouldn't even connect to WiFi. It sees all the available networks as usual, but when I click on our unsecured "Guest" network, it says "connecting" and then goes to "saved" and that's it. So I rooted the tablet, put Lineage 14.1 on there, TWRP, etc.... and during Lineage setup I got to the WiFi connect screen, andddddd same thing.. It sees the networks, but it just doesn't connect to any. I've turned my Note 10 into a hot spot to try that as well, same dice...
Before I conclude that this is solely a hardware problem, are there any last ditch efforts I should try? It's on Lineage now, so anything within that ROM that I could do, flashing a new modem.bin, etc.. just looking for ideas..
Thanks!

Just got my A100 yesterday and had really high hopes for it, but it appears to have done something to my home wifi.
Everything was going great with the tab until I decided to reboot the device. Upon reboot it would not connect to my wifi (it connected fine before reboot), just kept trying to obtain IP address and failing, disconnecting over and over. I tried factory reset and no dice, can't get a connection. So I figure I got a lemon and did RMA to send it back, boxed it up ready to send. Then I try and connect to wifi with other devices (Droid X phone and 3 Kindle Fires) and get the exact same thing.
My two desktops are running over wifi and work fine. All of the Rokus in the house work fine. Just the tablets and phones can't get a connection. WTF?
It has to be something the A100 did, nothing like this has ever happened to my network before, and it can't be a coincidence that it happens the very day the A100 arrives.
Anybody have any ideas? I am guessing it changed some setting but have no idea what it might be (or why in the hell it would do such a thing).
Any help appreciated.
Have you tried rebooting your wireless router? Some times a device will lockup the dhcp lease service, you'll be able to connect up to the router, but thats about it... usually rebooting the router resolves this issue.
Wow, I feel dumb... I guess that didn't occur to me since the desktops were working.
Anyway thanks for the reply, issue fixed, now I can get back to enjoying the A100
Last week my Nexus 7 (2013 wifi) updated to 4.4.3 and it has been working fine for the last few days.
Then suddenly it stopped connecting to my home wifi, in the space of a few seconds, the signal goes from excellent to weak even though I am only a few metres away from the router. It will not automatically try to connect, but when I hit connect it goes from a strong signal icon, saying 'connecting' then back to 'saved' then to 'disabled', then 'not in range' then strong again etc. Each time I try to connect it tries to connect then a second later goes back to 'saved' without trying to do it again.
I have tried static ips, changing the settings on the router, taking off security completely, changing channels, and it acts just the same.
It was rooted and with the toolkit have tried reverting back to stock and unrooting it and although the process says it is a success, I cant get past the first page as you have to log on to a wifi network and it still is doing the same thing.
Is this a hardware or software issue?
All the other devices in the house connect to the wifi network without a problem it is just this now which without wifi is basically a brick.

I don't understand this: you updated for 4.4.3, then reverted back to stock. Can you elaborate on this point, please?
If you did not try a data wipe, you can try deleting the following two folders and rebooting: /data/misc/dhcp, /data/misc/wifi

By stock I meant flashing a stock image and unrooting it. It was stock anyway but rooted. I also tried a full data wipe in custom recovery.
The problem is, I now can't get past the first page when starting up as you have to log into a wifi network before you can get into the phone.
(1)Try rebooting your router.
(2)You may be able to bypass the welcome screen by tapping on the four corners of the screen starting from top left and going clockwise.
[Note: I borrowed number 2 from Mooem on android central. You should thank him if that one works for you.

Thank you, but rebooting was the first thing I tried.
I also just tried tapping the four corners of the welcome screen but that didn't work either.
It is becoming apparent that perhaps it has a hardware fault as I would have thought a hard reset would have cleared up any software issues.
After a few more frustrating hours, I managed to flash a custom rom on it, no joy, then flashed back stock, did a full erase, nothing.
I then sat on the router settings, took off security, changed channels, changed frequency, still the same.
The I took the back off, the 4 springs are still there so it is not a connection problem.
So has the wifi just died?
The strange thing is after most logging on attempts, the wifi signal for the router dissapears or says disabled and then comes back again about 10 seconds later.
I cant get past the login screen to put debugging on so that I can lock the tablet so that I can at least take it back to where I bought it from. The tapping the four corners thing doesn't work with this rom although it strangely did with the custom rom (CleanRom 4.4.3).
Do I just bin it and buy another one?

I don't think you need to have debugging on. Just boot into the bootloader manually and then you should be able to lock it.
If you turn off bluetooth, then all is ok. Seems to be a bug in update to 4.4.3
So i recently got an update for my phone, and it auto downloaded it. I installed it, thinking it would bring improvements. Turns out, it messed up my wifi big time. Phone keeps forgetting networks it was connected to, and its a hassle keeping a stable wifi connection. It keeps disconnecting for no reason. No, its not a problem with the router. I tried resetting it and still the issue persists. Moreover, my family members phones and my laptop connect just fine.
Troubleshooting steps ive tried are restarting, and even resetting my phone. Did not work. Does anyone know how to fix it? It would help out a lot! Attatched screenshot with my firmware version. Thank you!
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
I asked this back in August and received no reply, so I guess I will try again. With the stock amazon fire OS I cannot get the hotspot to work, it turns on, says it's enabled, I then try to connect any device (have tried many pcs and tablets) windows says it's taking longer than usual to connect, then eventually connects. But then it will not get me internet access, just local only.
Now here's what makes me believe this is a fire OS issue, if I put on CM11 it works fine, no issue at all, but honestly CM11 is too buggy for me and despite what is said here, I get a better signal with the Fire OS. I am using Straight Talk, and using the apn provided by the sim/phone. I can get on the internet fine on the phone, just nothing for a hotspot. Anyone have any ideas?
