This is a problems I'm having now with my GS2 and ICS(current is Bezke rom and Pure rom prior to that). Both of these ICS roms exhibit the same problem, it will see the wifi spot (its a Apple time machine and the connection uses WPA protection), it just won't connect to it.... EVER. The router is also just in the next room, so it has a perfect strong signal.
I did not have a problem before the ICS upgrade, it connected to the wifi spot just fine. As far as I'm concerned this is NOT a hardware problem but in software. I have had this issue with MANY MANY other high end android phones (I go through a lot), so much so that I got a 2nd router and run it open just for my android phones. I've tried utilities that "reset" the phone settings to help connect (not sure what that means, maybe like a DNS flush or ipconfig release/renew kind of deal...) but they never work.
Ive searched online for this issue and apparently thousands of others have had this same issue, but I don't remember seeing any talk of what exactly the problem is, or what to fix it (aside from flashing another rom). I would rather not be flashing every rom under the sun until I finally get it working, but I might just have to.
I really like this phone (I also have a 4S but don't use it because I like this Samsung so much) and plan on keeping this a while. Its a GT-I9100 BTW and not a carrier branded device, I have it on T-Mobile US.
I'm probably going to try the official Sammy rom next and see what happens. FWIW my last phone that had this problem was a Optimus 3D and it was running STOCK F/W and still would not connect. C'MON GOOGLE! WTF, This is a problem, can we PLEASE get it fixed
Can i take it that you have tried connecting with no security setup on the WiFi router first .

Same problem here. Just upgraded two S2's at work. Went thru the process to 2.3.4 and 2.3.5 and once in 4.0.3 neither of them worked using our cisco wifi. Remember having the same problem on the old HTC Hero, but the Desire and the Sensation (both 2.3.5 and 4.0.3) works fine, as do iPhones and some tablets.
Problem must lie within the S2 since we have loads of computers and other phones connected. Have tried static settings instead of dhcp but the setup on the phone is quite limited.
Same here
9.5-9.7 Resurrection ICS based on XXLPH/XXLPJ won't connect to wpa2 secured University wifi. I've tried the official XXLPQ by Samsung and everything works like a charm.
It installed the XXLPQ so that is a no go. Tried connecting to a htc sensation hotspot and that worked. They just don't want to connect to the Cisco.
Encryption requres screen lock
I'm on campus Wi-Fi a lot. apparently "credential storage" used on these enterprise networks can only be used when you have a screen lock pin code set up
Does that help?
trying to find a way around it myself, I dont want to have to type a pin in every time I pick up my phone when I'm sitting in my apartment streaming pandora.
Sorry I forgot to reply back, but I ended up "cheating" and getting another router SPECIFICALLY for my android devices that dont like wifi security. I got a coupon in the mail for a free wifi router (N too!), its pretty low end but hey, it works.
Sure thats not really fixing the issue with the phone, but Ive gotten to the point of so much frustration, if I try any further to fix the phone and fail I'll either end up destroying the thing, turning to drugs or both.
Sadly, that last sentence was not hyperbole, Im serious. HOWEVER the phone is working, so all is well here
So, I've only had my LGOG for a day and a half and I am having issues connecting with WiFi. At first it worked fine but when I left the coverage area and return a few hours later it would not connect. Tried turning off the WiFi but it kept turning itself back on. I reboot the phone and it works fine as soon as it boots up it connects the WiFi no problem. It is my work WiFi and I had no issues connecting to it from either my iPad nor my HTC One X that will soon find it's way to eBay thanks to this beautiful LGOG. If no one else is having issues, I will call AT&T and have them switch it out. I just wish there was an easy way to back up everything, I mean my home screens and app locations exc. It takes so long to set everything back up the way I find most useful.
WiFi on my device has been excellent.

The Wifi performance of this device is unbelievable. I get the best speeds I have ever seen with any device including PCs. It's either a faulty device or maybe your work has strange security settings?
I had this same problem with my LGOG and my home wireless network. It just would sit and try to connect until I rebooted the phone.
That was on stock though. I have not had any more problems with it after flashing the base rom.
My work has standard WPA settings and it was connected fine yesterday. I left again during lunch and when I came back, same problem and had to reboot the phone. AT&T is sending me another one already and a free case. Can't be too mad about it I guess and at least the phone reboots fast.
Have you tried using the ATT smart wifi app? Fixed the exact same issue for me.

I haven't had any issues connecting to wifi, but I've noticed the status bar icon showing low signal even though it's actually maximum signal.

Twice My O.G. wouldn't connect to wifi networks even though it had connected to them in the past. I tried to turn it off and on and scan for the network that I am in range of and it wont show any networks it just says "not in range" when I am in range. So to remedy the situation I turned the phone off and then on. It has only done this to me twice but it's a real nuisance because both times I needed wifi. My phone is stock.
You're in a minority. This thing's wifi blows most other wifi implementations out of the water.

Perhaps you need to swap out your phone

I wish my wifi would stop re-enabling itself. It's chewing up my home bandwidth.
I have been having this issue as of late. It seems to have developed this habit in the last week or so. At first I thought it was Time Warner trolling me but it started happening at work. Something tells me it has something to do with the stock At&T Rom putting the wi-fi radio to sleep and not being able to bring it back online. Reboot fixes it most of the time but sometimes it takes a couple attempts. I have been hesitant to mod this phone still because I would really like to see CM working well before I flash. Also my instinct tells me another possible culprit could be IPv6 on certain routers. That, however, is far less likely unless someone with a decrapified Rom has experienced this issue as it would be a cross platform issue in this case. Anyone else have any insight? Otherwise it's time to get rid of the Att rom.

Same issue here. This is my second LGOG and have been happy with both except for some minor glitches on both with the keyboard freezing up as well as with the WiFi not re-connecting after leaving the area. A restart normally fixed both problems. My first one bricked after rooting and removing all of the bloatware (the phone checks for certain apps upon booting to keep you from removing stock apps). Tried a fix but I couldn't get a Rom at that point as the phone had been out on the market for under a week. I haven't messed with it since but I may try a new Rom and be able to fix the WiFi and get rid of all the bloatware that way.
Just got this ROM running today. No more WiFi issues at all. Some minor ui bugs I am OK with.

Seems like, as usual, At&T bloat ware is the culprit. I experienced the same on my Aria and Inspire. Hope this helps and good luck.
Also I had the keyboard problem but that went away when I switched to the Android default keyboard. One of the other reasons I decided to root was because rather than freezing, the Android default keyboard started typing then the auto correct broke and stopped displaying the words unless you touched the area you were typing in. It really bugged me when it started doing it right after I factory reset. Weird huh?

LG Optimus G Wi-Fi Receiver Disconnect Issue
Funny...I've had some weird home wi-fi issues on two of these.
To explain, I bought mine in December, stock OS of course, and immediately noticed it turning off my wi-fi every time I tried switching between the two home wi-fi SSIDs I created when I upgraded to DD-WRT. This also occurred outside my house, but stopped shortly after the nearly-immediate Android OS upgrade came over (and forced me to install it, I might also note; I'd read the thing was just more AT&T bloatware, but two or three boots later, apparently I got no choice, and it auto-installed).
The good news was, somehow, this 'update' somehow stopped the thing from turning the wi-fi off when I switched between IDs (my base router has a 5G 2nd network which I wanna use when I'm around it, but DD-WRT won't support, as far as expanding it--thusly, I have another 2.4GHz signal I use and relay out around my yard).
That bad news is, though, that I screwed up the phone with the Root Toolbox (Lite) by merely fiddling with their bootanim settings on that original phone. And I mean bricked it, solid.
I'd never bricked any phone, so this ticked me off. Luckily, I was still within 2 days of my 30-Day Best Buy in-store replacement warranty, so I took it back, they fiddled too, and gave up on it.
Hence, my 2nd phone...which now, even after the system update direct from AT&T, still turns off my wi-fi every time I try switching to that 2nd SSID, so I'm left wondering if it was even the same update; I don't think I did anything else, and can't see it as a settings issue, because it did it right out of the box, and the first one stopped after the only system update before I got a chance to even figure ANY user settings out, much less any network ones.
So, now I'm 'going shopping' for 'some PlayStore app' that will skip this B.S. and automatically connect to the strongest home wi-fi signal (within reason--sometimes they're equally strong), without obnoxiously turning off my wi-fi receiver as I look at it.
This kind of malarky could spoil some phones for some people, but I'll struggle along due to the speedy quad-core in it [sigh...wah!].
I guess I'm a big baby, seeing as how I don't write one iota of code, but my personal haughty view is that any dedicated wi-fi devices should have better wi-fi connection than any Windows OS made...and, so far, this'n doesN'T!
What a dumb thing to let happen in such a potentially awesome phone...[AT&T!!!]
This might work or not but can't hurt to try. Apparently some people in the new snowleopard JB thread was having similar issues and for a few, changing the security from WPA2 to WEP worked. Although mines been good and fine on WPA2 but worth a try.
Using wep in 2013 is beyond retarded.

DUDE! Senior Members here can be a little uppity and rude...even if they're completely correct.
Glad you called out the 'behavior', and not the 'member', though...
but enough of the technicalities...I'm still looking for solutions...beyond blaming AT&T (too easy), or even the strangeness of getting into blaming some weird kind of manufacturing errors (QC at best), I'm left waiting for a substantial OS update (like, oh a better place of decimal, perhaps?), or worse, an app...anyone look at the state (and sheer number) of 'wi-fi' apps? Anybody here can guess, they number in the thousands, and a Play search for 'wi-fi' gets you astronomically different results from 'wifi', even, so I'm not sure I need to be looking at that.
Maybe it's even somehow that, with the first phone, I noticed this, and somehow added my own home network to the AT&T Smart Wi-Fi 'bloatware' that came with the phone (not the worst evil they've ever done, so far, BTW--it does exactly what I imagined should be going on in the background while you're driving around, indexing locales with free Wi-Fi for you to choose to save later...an idea I would call 'Tarzaning', if you get my drift).
I'm gonna try changing two settings in the AT&T 'Smart Wi-Fi' bloatware to 'My Spots' temporarily, at least, to see if it'll latch onto my home stuff more aggressively. I just can't wait to report back my fantastically successful findings here (right after I buy the domain name 'snarkasm.net').
Oh crap...it's already taken.
Is the AT&T smart wifi thing enabled by default? I can't remember. I thought it sounded useful so I played with it a bit but ultimately I didn't like the way it worked so I disabled it.
Still wanted some way to auto-enable/disable wifi. I didn't have anything to go on, but I picked up "Smart WiFi Toggler" which seems to work well. It uses location-based rules (based on cell signals) by default. I also use AutomateIt to turn off mobile data once wifi has been on for 1 minute, and turn on mobile data immediately when wifi disconnects. I have no idea if this saves me any battery life, but I do it anyway.
so i have this problem for about 3 months now,
so I'll explain the problem I am facing,
I'm connected to wifi unless I'm an inch close to the router, so if I go away, the connection will be disconnected, however, in my work, I am connected to an access point which has put a big smile to my face, but apparently when I went back home, I faced the problem again, and I guess I would be connected to that only access point, which is the first time I've seen since i got this problem, all the routers/modems I tried to connect was a failure(saved, secured) since my phone met this access point.
I already tried Factory Reset, Flashing custom modem, *#0011#, deleting data/misc/wifi, changing settings on router and many many more as I've put an hour of fixing this every single day. none of this works. for what I recall, all I did was download an GPS app(I don't remember what it is) and then poof, wifi is doomed.
I have my iPad and my laptop connected and there's no issue with them, only on this phone.
I'm running 4.3 btw,
does anyone know how to fix this problem? my brain hurts a lot and I don't know what to do. please help I'm dying, thank you

So I have completely given up on my LG G5 for 5 months and today I decided to see if maybe I could get it updated to Nougat to see if it would fix the battery drain I was having. I couldn't get that far. Now the WiFi and Bluetooth say Connection not allowed and I can't connect to my home wifi of course. Well I decided to check the MAC Address to see whats going on. My current MAC Address is 02:00:00:00:00:00. Something doesn't seem right about that.
My ideas that I have done:
4 Factory Resets
3 Airplane Mode Reboots
2 Safe Mode Attempts
1 Clearing of Cache
At this point I dont know what else to do. I really miss Android and I am currently using an iPhone 6S. I just want to get back to the roots where I belong on the Dark Side. Please someone help me with this issue, I even contacted LG support and they told me they can't do much about it. Same with AT&T they aren't helpful over the situation. This seems to be an issue a few people have had but I think it's time to get this issue fixed.
Please help I posted this on the AT&T LG G5 thread and no one has reply in over two weeks.

Try taking the Sim card tray out and booting into Android and see if your correct wifi Mac address shows up or not. I know on my t mobile h830 that had happened that my Mac address would show same as yours unless I had Sim card tray out. If it works, try doing factory reset with it out and booting into Android and all then put Sim card in and see if it sticks. Otherwise not really sure.

If nothing is working, I'd say it's a hardware issue with the Bluetooth / wifi card and you'll end up needing to send it in for service then.
Hi...did you ever figure out what was wrong with your LG? I'm having the same issue with Bluetooth on my rooted LG G3, it's saying 'Connection not allowed'.... Tried everything to fix it short of bouncing it against a wall. Can you help?
My Phoenix 4 (LM-X210APM) has this problem. I got it from my friend's dad and it always had this issue.
