LG G4 on Android 5.1 fight over WIFI - Android Q&A, Help & Troubleshooting

So I bought 26 LG G4 h810 to organise VR Field Trips using Google Expeditions.
At first I managed to connect only 4 of them. I thought it's perhaps a router. This app relies on WiFi P2P btw. So I changed TP-LINK router worth like 60$ to Asus RT-AC 5300 which is quite high-end. Not much changed as yesterday I had trouble connecting even 2 devices together.
This morning I realised that G4s with Android 6.0 //I received 5 of such// are actually stable and work like a charm together. So I thought I finally have a solution - I'll upgrade the rest - flash with kdz through LG UP and I'm good to go. Well I'm not. The 3 upgraded phones act just the same as they did on 5.1.
It's a funny thing really, to see - 7 phones connected - 2 of them on v5.1,
I connect to this wi fi (5ghz btw) another 5.1 device one after the other, and some of the phones disconnect just one of the other 5.1 device in the network, some of them kick out all the 7 phones. As soon as I turn the wifi off on the newly connected 5.1 phone, all the rest connects back on together.
By kick I mean Expeditions app is reconnecting. Sometimes it goes as far as disconnecting wifi completely, but usually it's more like internet becomes unavailable. And that's btw a funny thing, cause Expeditions doesn't rely on internet connection - the router theoretically can be offline - however when the phones get to fight over wifi (when there are 3 android 5.1 LG G4 trying to connect), notification comes up "internet is unavailable" and with that Expeditions connections are lost aswell.
I spend whole days on it since like a week and am slowly getting frustrated so decided to write to ya not only read.
Yesterday I rooted 3 of the 5.1 phones to get rid of AT&T bloatware and unlock hotspots - it didn't change anything.
I think it's some sort of direction, the fact that 6.0 devices work as expected and 5.1 ones not, but the problem is so specific, that I can't really find relevant information online.
I also compared the working and not working phones today with antutu and antutu officer and it seems they are legit. Had doubt as I bought them refurbished from Aliexpress.
The wifi works perfectly on each of them seperately as I updated apps on them and experienced no issues... As long as I updated max 2 devices at the time.
Am thinking of interference of some sort, or like device id conflict or something... Will probably also try to rename the devices maybe something like confuses the router, I don't know. Please help.

weak wifi

Does anyone else have a issue with their S Tab, only getting weak wifi signal, even from a wireless router your are right next to?
I have a wireless router in my living room, and everything else i have to include my other tab and laptop get full bars for the wifi, but my S Tab only gets about 3 to 4 out of 5.
Just curious as to if this is just a flaw in the Tab, or maybe mine has an issue i should have looked at for repair, or replacement.
i get a full signal on the home wifi and using my mobile as a hotspot, not sure why yours is getting a weak signal.
Im not sure either, it still works fine, seems to run the browser, downloads/updates fast still, maybe the little icon at the bottom by the clock is inaccurate.
I feel it is better than on my SE XPlay

I have had a bit of the same issue. When I first got it it seemed that it picked up my home Wifi last above all the others around me.
Once it did finally find it it only showed a weak singal, after I put in my password it jumped up to full strength. this has happened to every location I went to. Once i do connect it works great (on a side note people have complained that my wireless internet sucks at my home when they tried to connect with there laptops)
I seem to have a similar issue. Works fairly fast but looks like I only have 2 bars.
Yeah I have noticed this and using wifi manager the signal goes up and down but seems fine on my arc....

I don't have an issue with the signal but it takes forever for it to connect to my AP. It's taking at least 30 seconds to make a connection.

sony tablet s wifi issue
Hi all,
after weeks of study here is what i found out:
- wifi issue is not a hard ware issue, it is simply the software.
- wifi issue occurs only with certain routers with both N & G channels , Especially Netgear and BT.
- Wifi manger app makes it better and less annoying, issue still there but less occurring. try different channels.
- Tablet S for some reason does not like the channels used by certain Routers.
- do not bother with wifi lock app, does not do the job and steals ur battery.
- after weeks of trial, tablet is just great, but needs attention from Google.
SO
My friend's wife works for Google, when asked for the favor of the insider , engineers in Google said, first stage is to roll out Xperia release 5 to try and fix problem, then both S and Xperia will get Jelly bean with a definite fix. Testing as we speak.
all I can do now is get a good router and hope for the best.
I too have a problem with my new-ish Sony Tablet S (which I wish I never went to 4.0.3 r5). Sitting anywhere in my house I get 4 or 5 bars - I have a great DLINK Router and a repeater in the other end of the house. Both on the same channel family and get full blast wireless all over the house.
My problem is (the router is locked into N only mode as everything in the house is N) - even with 5 bars, the NETWORK information from the tablet's info panel says I am at 65MB/s. Why so slow? My older than the tablet laptop with built in WiFi get 150MB/s, and the router is capable of 300MB/s (dual channel router).
Can anyone explain this?
Also if anyone can direct me to the steps and files to get my tablet back to the 4.0.3 (pre R5 version), I would be ever so happy. I hate all the new additions - none of them good that R gave. My biggest gripe is the removal of the DLNA app that worked great with my MEDIA Server (windows) and streamed my .M4V ripped DVD collection, that my HTPC also uses, flawlessly. The WALKMAN and MOVIES app in the R5 software - for use of a better word - S U X !!!
I already called SONY to find out how to REVERT and of course got the answer, YOU CAN'T. You would think that with over $20,000 worth of SONY equipment purchased in the last 8 years they would help.
Thanks,

[Q] Sony Tablet worst Experience :: Got replaced piece, but same again :-(

I own Sony Tablet S since last 90 days but has a lot of problems, it has been at the service station due to its issues for more than 45 days.
The features/functions included are really nice, but the company doesn't care for the customers.
I called and mailed the Customer Care for more than 20 times, but didn't got a revert even once.
I somehow got a replacement, but the same issues were there in that one too.
If not wrong, I got the promises from the Customer Care around 20 times to revert back, but just got 1 revert back.
The major issues I am facing are
1. Wi-Fi disconnects regularly
2. Wi-Fi doesn't have proper range which you can even see in the youtube link as follows:
http://www.youtube.com/watch?v=8FRb855gBMo
3. The device hangs a lot when loaded, stops responding for a long time and the only solution remains is to Restart/Shutdown
4. The screen doesn't get unlocked many a times even upto 30 seconds after pressing the unlock button.
5. GPS connectivity issue: Connection to GPS only remains if you stay at a place, not if you move anywhere from a particular place.
BUT THE WORST problem I am facing is the WORST COMPANY SERVICE.
The stupids don't just know any status of the problems most of the times.
They promise to call/revert back, but I didn't get any reverts of my e-mails from the 13th of April 2012. I can't understand why is this happening to me ???
Any1 facing any of these issues ???
Please provide me reverts unlike SONY
I have the same problems 3 & 4 as you. And most probably caused by the WiFi connection.
I have sent in my Tablet for repair cause after a month of usage - the battery cannot be charged.
Hopefully the ICS update will solve these few problems.
I'm from Singapore and Sony after-sales service sucks all around the world except USA, Japan & maybe UK. That's where all their customers are at. =)
Sorry to hear you're having problems.
If you've had the same wifi issues with 2 tablets then it's unlikely to be a hardware problem and more likely to be a compatibility or settings issue between your router & tablet.
I'd try connecting to another router or network or if this is not possible look at temporarily removing security and possibly changing channel settings on your router. There are other threads here which discuss some wifi issues. Make sure your router has the latest firmware installed and do make sure you've updated to the latest version of Android for your region as this has been known to help
Wifi will disconnect when the tablet goes to sleep but should connect again within 10 secs or so of waking up Unless you download an extra app which forces constant connection.
With respect to the laggyness and crashing what apps do you have installed? I'd be tempted to point the finger there first before blaming the tablet, might be worth going through them and seeing if you can narrow it down to a dodgy app or one that doesn't like the Sony much. Certainly like above get the latest android.
I hope the issues get sorted swiftly for you.

Wifi is a known unsolved issue the rest is not really nmormal, but why don't you try to contact sony vaio service wich contains tablet s also
Agreed with James. If two tablets have WiFi problems, it's almost guaranteed that is a problem with your network environment, not with the Tablet. I have never had a problem with the WiFi and it always reconnects easily.
Also +1 for the app suspicions. Most of those issues sounds like they could be coming from an app (particularly 3 and 4), so try factory resetting your device then installing apps slowly one-at-a-time, waiting about 24 hours between installs to see if any apps cause this behaviour to return.
As for replies from customer service, I can't help you there since Sony replied to my only support Q within three days of my message. Make sure you have the right address, and then try Vaio Service.

Thanks for reply dude, but you'll really be amazed to know that
My router doesn't have any issue, it has been upgraded to the latest firmware.
To add I connect the same router with 2 Nokia E6-00, Nokia N8-00, Nokia E63, 2 Sony Vaio Laptops, 2 PC with a linksys usb modem, Samsung Galaxy S, Nokia E71, Lenovo Laptop, Samsung Galaxy Note, Sony Walkman Live, a lot Iphones of my customers get connected to it, a lot ipads get connected to it and none of them have problems, why this is the only 1 ???
About softwares, again a shock this is a problem when my Tablet was just opened from the box even, it is still there and I guess will remain forever, and if you guys don't know, just check the youtube link I provided, it explains a lot.
Anyways thanks for the help
And even I use 4 Sony Vaio Laptops and always suggest Sony to my friends and relatives, but this time I faced the worst cause they promised me to revert back almost 20 times, but I got a revert only once. What the f**k
Guys please reply if any of you are facing the same problem or not ???

Tablet S not holding Wifi Signal

I recently purchased the 16gb Sony Tablet S and am contemplating on whether or not to return it by the 30 day window due to sporadic wifi connection at my apartment. The issue is not as much the reobtaining wifi after the screen unlocks, as it is the general holding of the wifi connection when the screen is on.
I've isolated the problem to my specific router, as it works PERFECTLY at my GF's apt and my parent's house. Always connects right away and stays connected. However at my apt it doesn't always connect right way and have to manually turn the wifi off and on again, and sometimes have to manually hit connect from the wifi screen. When it finally obtains IP address it will connect, but most of the time for only a short period (like 20-30 seconds) before the wifi signal on bottom right just disappears. Then I have to toggle the wifi on and off again and try again. Very annoying. Sometimes it will connect though, and the wifi holds up like it should.
Here are the fixes I've tried so far:
* Reset and Factory Rest device
* Forget/Reconnect to network from device
* Update Router Firmware
* Configure Router - g/n mode and n mode from b/g/n
* Set Router Channel from auto to 1,6 and 11.
* Wifi Lock App (doesn't work and drains battery)
Personally, I feel like the tablet itself has an inferior wireless radio. Compared side by side to my other wifi devices, it has noticeably less signal at the router and diminishes quicker the farther away you go. Now, this doesn't really bother me as I'm usually always near my router. However, when I was scanning all the wifi networks around me (in cmd: netsh wlan show networks mode=bssid) I found over 30 networks around me all using the full channel spectrum. I've tried every channel on my router, but 11 seems the best.
Would a crowded wifi area affect the tablet? But again, my laptop, 2 phones, and PS3 connect at every channel with no problems at my apt. At my parent's house and GF's apt there are only 1 or 2 other available networks that could also be on my channel. That's the only thing I can think of.
I just don't understand why only the tablet is having wifi problems.
I have about a week left to return it, and would like to keep the tablet, but running out of patience. Next, I think I will try using MAC address and see if that works.
Any help would be appreciated!
Try this!
I had the same issue.
I solved the problem
1 - turn off wifi.
2- in accounts - turn off "auto connect"
3- turn on wifi ( test if work )
4- reconect the accounts
too simple .. but works , try it.

Thats certaintly not the problem since i have so many devices logged in on my network, and not having the same problems,
The Wi-Fi on Sony tablet has known issue's like loosing connection when screen goes standby, even if you checked this in settings never to shut down.
The steps in the post above can be the sollution, and if not, sony will make somehow a repair or a dev would fix this. goodluck.

Thanks. I tried that sequence and it seemed to work for a little bit, but then the problems reoccurred.
Again, the problem is not just that the wifi doesn't pick up right away after standby, but also, and more importantly, it looses wifi BEFORE the screen goes out while I'm using it, repeatedly.
Its very annoying and only happens at my apt and not at other networks. No other device on my network has this problem.
Nobody else has had this problem before?
I remember from older posts that tablet s has problem with certain brand routers. What routers are used in your places.

Its a ZyXel brand router that doesn't work. I'm pretty sure the one's that do work are both Linksys. The ZyXel router is probably a cheap one because it came bundled in a promotion from my ISP.
I guess I could try another n router, but still find it strange that all my other wifi devices are fine with the current router.
Wifi Signal
Sony is not as reliable as it used to be... My Tablet S keeps loosing WiFi signal, and the solution I found was to turn off and back on the WiFi. This fix the issue.
However another very annoying problem is that very often I need to hard reset the tablet as it locks the screen with no other way to recover it. Shame on Sony. An the annoying side flash light is ridiculous. I used to have an A100 that aside any design issues, worked perfectly never had any operational issue with it. Should have upgraded to a A500...
What worked for me.
I bought a Sony S as a birthday present for my wife. That was yesterday and today she went to work and left me to set it up for her.
I have a Cisco E3200 router. The tablet could see my router and connect to it but would drop the connection after 5 seconds.
Well, that was the first hour and a half of my day.
Finally, with nothing else to try, I set up a guest account on the router. The tablet found it and connected to it on the first attempt and has been connected now for over four hours including multiple restarts.
I have no idea why this worked. I just know that it did.
Clive.
Same issues here when docking tablet sometimes, but my work around is to turn WiFi off, and hit Fast Reboot ( app by Great Bytes Software) then turn WiFi back on. Fast Reboot seems to do a soft reboot on apps and system and it only takes a few seconds.
Hope this helps!

Wifi Issues
I bought the 32G version from Woot recently. The WiFi reception is awful. I am on my second unit same thing.
4 feet from Router (on 2nd floor), 3 bars out of 4. 15 feet goes to 2. Downstairs goes to 1 bar 1MBS. And drops like a hot potato. Sony has sent a RMA for repair. Being this is my second unit with same issue, I doubt there is a fix.
I use a LAptop, netbook, android phone on the same router. No issues. They all work well, even in the basement!
Updated to 4.0 on my original unit, no change.
Just ranting here, hoping for a surprise fix. Other than that Mrs Lincoln how was the play? I love the tablet otherwise. Will probably throw and a spare router downstairs or feed it off my 4G phone. Now that really sucks..LOL
Anyone else
4.03 can solve this problem?

I have tried 3 different Routers.
Verizon/ActionTecMi424
CheckPoint Z-100G
Linksys WRT54GL
No change no difference.
I finally installed another router on the other floor. Now it works in entire house, but have to change router connections if I move to a different floor.
The big question here I think is:
Is every Tablet S this way or do we have some bad samples? Software or Hardware. Sony has given me and RMA # to return for repair. I am hesitant to do that. If there is no fix or all units are this way.
I am not 100% sure but from my own testing I found it working 90% of the time everywhere else, here is how I tested:
home netgear, does not hold wifi , have to refresh page all the time to browse internet.
Work ( different router not sure what type yet) works just like a dream, fast no wifi drops no refreshes needed.
took it to most free wifi spots, not a problem.
friends house BT, Same issue again.
Wifi manager made it a bit better yes ( have to test now on channels 12 , 13 or 15 , wifi lock app does not work.
I hate to get a different router to get same issue at the end. however different posts elsewhere suggested setting router to N on and G off channels testing each time you make a change, on tablet set to manual ( have not done this bit yet).
It's not like we are all being picky here with Sony, we like the tablet itself and we bought it with a lot of money, we want to be able to browse the internet download things without getting our livers and kidneys enlarged.
more to follow , I am really hoping to be able to get my friend's wife update as she told us GOOGLE IS VERY AWARE OF THE ISSUE.

WIFI Issue fixed
All,
there was an update last Thursday that fixed the wifi issue, I am not really sure what but my tablet s now holds and keeps wifi everywhere.
I had issued before with netgear and bt routers and after last Thursday it was just fine, i need to review the recent updates done and Let you all know.
I tried it everywhere and works perfect, download speed is perfect , not one drop of wifi so far.
I assume either Sony or Google did something here as it was getting an update last Thursday that lasted about 10 minutes, could not figure out what was that update yet.

[Q] Linksys WRT610n, Lumia 920&people hub

A few days ago i got my Lumia 920, and pretty soon i discovered a networking problem. When i am connected to my homenetwork, the people hub refuses to update facebook-streams. Sometimes it does, but most of the times its just "looking for updates". I have this problem only when i'm home. When connected to the wireless network at work, it works just fine - it's fast and updates every time.
I guess there is some parameter on my router that the phone does not like, but i dont have any clue what it could be. I'm running the newest firmware, no security is enabled. The problem is on both 2,4 ghz and 5 ghz.
I run "dhcp-reservations" so the phone gets the same ip every time - i also tried without reserving a specific ip to the phone. It has no effect on my problem.
I tried to enable the log, but the log is not very informative - its just telling what IP-adresses its trying to access.
This is the first device i have that is having a problem with my router. I have had three windows phone devices before, i have had iphone and one android phone, and of course laptops. I have never experienced this problem.
Would be very thankful for help solving this. I am not skilful enough to figure out what could be the problem. It works like a charm "everywhere" except when i'm home - so it must be my router that it does not like.
920 and WRT610n
I have a 920 and a wrt610n as well. A while back, I reflashed the firmware on my router with a third party open source product from dd-wrt.com. The firmware provides a lot more options for the router, and may help with your issue. I used the "mega generic" version of the firmware. Follow the setup carefully and let me know if you have and issues. :fingers-crossed:
I have exactly the same problem with WRT610n! Hope there's somebody can provide a solution...
Sorry to bring it to u guys, but some particular brands do not "like" each other. For instance, D-Link has an issue with iPhones and iPads, now this has issues with Lumias...
Possibly some reflashing of the router might get the things done, I cannot tell. I have a WR240G - and it works perfectly with every device, except for iPhone5 (in order to work with it, all security must be shut down)

Motorola g8 power 2020 wifi issue

Hi All.
My first android phone was an HTC Magic, and in all these years I have never had such a nasty phone. From the first day the wifi has never wanted to work, as I move away from the router the connection drops, or disconnects, a shame. I bought the phone in Italy in December, on Monday I got the update to Android 11, the phone is overheating and furthermore working with the gesture is impossible, you know the swipe up to see all the application running..now it's impossible, the wifi always sucks.... I work and I can no longer write on the motorola forum to ask for explanations and receive meaningless answers, reset the phone, send me the logs, deactivate this one, try disabling this. Do you know an easy way to solve the problem? Also I noticed that with antutu benchmark my modem also supports 5ghz wifi? Why the hell they didn't they enable it? Sorry for the outburst but this is the first time I have such problems with a stupid phone.
