Galaxy A5 2017 - Wi-Fi problem - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

I bought a brand new Galaxy A5 2017 a few weeks ago. Everything was working flawlessly, and since I was mostly using my LTE connection to use internet, it has been just now that I've noticed that although my device connects without a problem or interruption to any wi-fi router, depending on what router I'm connected to, I have no internet access. On the routers where I have no problems, the internet connection works flawlessly. On the other ones (including the one at my house) most of the time there's no internet connection, even though my Android stays connected at full strength at all times to the router. We have multiple computers at home, and several smartphones, and this Galaxy A5 is the only one that experiences this problem. I've done a factory reset, then reset the router but nothing seems to work.
Now it's unfortunately too late to return my device for a new one, so if I want the store's assistance, I must sent it to their repairing unit.
I've searched online for other examples where people might be having this problem, but found nothing quite like my situation.
Does anyone have a clue what might be going on?

[Q] Reboot router to connect to Wifi

I'm puzzled by the behavior of my phone. For probably a week at a time, I go to work, connect to a WIFI there, then come home, connect to a WIFI there. No problems at all.
Then it seems like after a week or so of 'being good' sometimes I'll wake up the phone and it will see the network, but will not connect to it, asks for passphrase repeatedly (WPA2-AES Cisco E3000 router) but just will not connect. I have found no way to trigger the phone to reconnect (and I refuse to do another hard reset because that is no solution at all).
The simple fix is to reboot the router. Presto, the phone will connect almost immediately.
I am willing to accept that maybe something is wrong with my router, although I have 3 laptops and a couple of IP cameras, and an Xbox that connect wirelessly all the time, and I never ever see this refusal to connect on any of those devices, and my wife's Blackberry will also connect whenever. So I'm thinking its my phone.
So for the experts out there, what is it about rebooting the router that fixes the problem?
I only recently learned how to get into the manufacturer's special app, so I'm going to pay attention to my IP address next time I have an issue, and see if it actually changes when I reboot after this problem occurs again.
Where does one discover how and what can be tweaked in the secret app? I'm cautious but not afraid....hey, I've edited the windows registry countless times on my PC and never toasted the OS yet! Does that count for something?
Add: I had this happen once at my work WIFI, using an ancient DLink router using WEP. At the time, I was trying out a bluetooth headset (Plantronics Backbeat), which worked, albeit, after I was done listening to the podcast, be darned if I didn't get into this refusal to connect thing, and unbeknownst to me, I was using the 3G data connection for what I thought was a wifi broadcast. That sucked 175 megs that day! I was a bit pissed about that. I have not used the Bluetooth since then.
Rebooting my router at work fixed the problem but I hate doing that, because I've got other equipment on that network that likes to be permanently connected.
the same happened to a frined of mine: interoperability issues with that model of router and the phone, changed the router and after everything worked perfectly, that sucks, but it is
Had a similar problem, and simply could not pinpoint the cause. Solution? I resetted my router to factory settings, and started to change all the settings from scratch to my desired settings. One thing that helped solve my problem was that I changed the default IP address used by the router (in my case, 192.168.0.1) as well as the IP range to something more ... random. Also, I limited the number of allowed IPs to 10 rather than the default 100...That helped. Never got a disconnect or problem connecting again. I had the same thing happen on my mother's iPhone and my brother's Galaxy S, and this solved it.

Wi-fi conections and my galaxy tab

Hi again, since my last problem, that my galaxy tab did not wanted to turn on, I got a refund and waited until the machine came to my country..... months later, I could buy it at walmart, and all went fine, I got a 16GB wi-fi/3G tablet and went to a friend's house to use it, wi-fi worked well, then I bought a router, and installed it in one of my houses, and all went fine, I could even use it 20m away, then I installed it in my actual house and first it came ok, I could connect it, and worked for several days, went away and used the 3G internet, and came back and used the wi-fi because it has better speed, and it started to don't work, so I reseted the router like 3 times, each time it didn't work, then I contacted a friend of mine that works installing routers for companies, and he configured mine so it had a better security and values he knows that would work better, and indeed the problem was solved... for a couple of days... now, it says connected and it does not charge the pages, or if I "forget" the network, and charge it again, internet works but it loads pages partially it does not load them completely. On my phone and laptop the internet always works, in the tablet that is the problem... so what could it be, or how could I fix it?
PD: this is really strange, because normally it happens either when I shut down the router (because it is right besides my bed and the computer (big desktop) makes noise) or when I leave the tablet in stanby for a day or so, I write this because now I just restarted the tab and internet worked as if anything had happened...
I was recently having problems with wifi also. Mine was connected to my network but I couldn't get on the internet. This happened after a few weeks of ownership with no issues. I found this article and it pertains to my issue, not sure if it will help you though. You do need a rooted device to be able to do this "fix". It worked for me though.
http://steve-shaffer.com/2011/02/samsung-galaxy-tab-wifi/
Ok thanks so to root it, is the method suggested in the article safe, or what could I loose with that procedure? meaning, do you know a trustfull procedure I could follow?
I had the same problem too recently...works well at my friend's place but not with my router...it seems that the tab works well with static ip and not with dynamic ip address with we people usually have...
Oh , just read that link...i was about to say the same...
There s another way...
Without root,
reset your router
go to your wifi settings
go to wifi channel
set the channel to 11 (6 or 4 works too)
these channels tend to workout the problem i heard...worth a try right...
You can try this before you root

G2 Verizon - Wifi Won't Connect

Has anyone had any issues connecting to Wifi networks on their G2s? I got the verizon version on Saturday and haven't been able to get the phone working on 2 different wifi networks. I can connect to the wifi network just fine, but I can't access the internet at all. I can confirm that other devices are able to connect no problem.
Curious if anyone has some thoughts on how to potentially fix this. If not, will be heading back to Verizon to get a new one. Thanks in advance for the help.

I have the AT&T G2 version , it will connect to any wireless router but the connection will last 5 seconds then no internet, this is totally unacceptable I upgraded from the G-Pro and may go back as that never had this issue, I did read LG had a similar problem with the Nexus 4 and Optimus G
Mine works fine. I have a VZW G2 and an ATT G2 connected on the same router. It connects to both G and N networks.
No issues with my Verizon G2.

Did you try rebooting your router? I see this at home with the families iOS devices a lot, especially after heavy data traffic. I'll turn off the router for a couple hours or overnight and the next day all is well. Router is open, no encryption.

I have the exact same problem. It will sometimes transfer some data using browsers, but nothing on facebook, pandora, or the play store it will say connection lost or not data connection.
My wife has the same phone and it works no problem and also the laptop. Must be a dud wifi radio or something like that. Mine is going back to the store tomorrow.

Are you trying to use adblock by any chance? I was and it was causing the same issue you have. I uninstalled it and changed my proxy settings back to none and wifi is working great now.
Just received my LG G2 White brand new from T-Mobile about 2 hours ago. After many attempts to troubleshoot the issue it all failed. The problem is Wifi will connect to router and even work but after 30 seconds the connection goes down. The actual Wifi signal shows connected but no internet it gets stock. We tried resetting the phone and toggling with different features but still it did the same thing. T-Mobile is the worst they were trying to have me ship the phone back and leave me phone less for days. I complained and they are sending another one overnight but have charged me for the phone on my account. Mind you I've had months of bad service, after all I think I got a defective phone. I've read some other people having the same issue with other carriers. If I get another one with the same issue I'm jumping boat. If anyone knows of a work around let me know. I tried 2 different routers same issues connects then it randomly disconnects and stops downloading or transferring data.
Reset Phone - didn't work
Turned off mobile data - didn't work
Turned off wifi sleep - didn't work
I'm on Verizon. I have trouble with initial connection to wi-fi. It says obtaining IP address for a very long time. Even if I have a very strong signal. It takes about five minutes. It eventually connects and works fine. Then next time I try to connect to that router it works fine. It's only the first time I try to connect to a new router.
I just got this phone over the weekend and I was also having trouble connecting to my home wifi.
It would stay connected for 30 seconds or a couple of minutes then disconnect however the entire time the status under the Wi-Fi settings page says Connected even though I couldn't access the internet or the admin page of the router. Frustrating. If I turned off the mobile data, the wifi, the phone, the router, or some other unknown combination of events it would then reconnect again for another 30 seconds to a couple of minutes.
I called Verizon, they told me to take the phone back since I was within my 14 days. I did this and was optimistic. Then the new phone immediately experienced the same issue.
I did some more research, changed my router from 20 mhz channel width to auto 20/40 mhz. Not sure why it was set to just 20. I thought that would fix it. Nope.
I tried to set my phone to use a static IP, that didn't work either.
Then last night I tried the WPS Push Button option instead of using a password. This method worked and my phone stayed connected. I haven't had a chance to repeat my steps to verify it works again but wondering how other people are connecting, password, wps push button, wps pin? WPS is not my preferred option due to the security risks but just trying to track down what works and what doesn't.
I am able to connect at work just fine using a password.
I'm having a similar problem - my work network has no problem connecting while my home network almost never works with this phone (~25% of the time, other devices have no problem). Occasionally, resetting the phone or just turning on-and-off WiFi fixes the problem, but more often I just give up and use 4G. Anyway, if anyone finds a solution, please post! This is such a standard feature that should really work out of the box.
In case it helps, my home network uses "WPA/WPA2 PSK" security and my work connects to "802.1x EAP" security - also I'm not adverse to changing the security options if it fixes the problem.
Thanks! Nick
After reading more on this, I've decided this issue is router related not phone related.
I discovered my router reached end of life in April of this year is no longer receiving firmware updates. Newer versions of my router have received multiple updates since then.
I will be buying a new router. I report back on if it works.
I really don't think it is "router related" as all my other devices work as expected with my router. A new router may fix the problem, but I'm pretty sure the phone's WiFi is buggy and not the router..

In my situation it really appears to be how my router is handling the connection when I connect with a password since I can connect with limited security.
Does your router have a firmware update available for it? If so, have you applied it?
Received my new to me router yesterday with updated firmware as of 10/7/13.
My phone was connected for a few hours last night and I have not had any problems today. I'll report back if I start experiencing any issues but getting rid of my old, end of life router and replacing it with a newer router worked for me.
I did not buy a brand new router either. I went with a cradlepoint mbr95 which has been on the market for awhile and has already had a few firmware updates.
Check you wireless security settings
Had a similar issue to this and it seemingly was resolved when I moved the wireless router security over from WPA/WPA2 personal to WPA2 personal only. The phone found the WAP and connected right away. I tried to reproduce the behavior but alas I have not been able to do so. Perhaps this will help others.
hi guys
i found the problem
it happens just when you disable auto update in "settings>general>about phone>update center>software update>check automatically"

It's your router, not your phone(s). Can't believe you haven't considered the common factor.
There's nothing wrong with the WiFi on these phones. Hence you can't find answers to problems that don't exist...

I have no problem with wifi whenever I change new mobile phone . In your case you can try resetting your router.
I have reset the router and like I said in my earlier post, the problem was not just in my house with my wifi, its every wifi we have tried in different places all over
There isn't nearly enough data here to make any sort of assessment.
-Have you tested your connection settings from the phone? Try something like Speed Test to see if it can establish a connection.
-Does Wi-Fi stay connected or does it drop in and out? Does the Wi-Fi icon change to being grayed out? Does it turn itself off under your settings?
-Have you tried changing the connection type on the router? WPA2 to WEP, etc...
-Have you verified that the network is broadcasting an Internet connection from another device?
-Can you see the phone on your network from a computer?
-Have you tried pinging an IP address from your phone?
More than likely it's a DNS or DHCP issue. But I don't want to recommend any troubleshooting methods until the problem has been isolated.

Every device in the house works fine on the network. I play xbox live all the time with no problems.No lagging whatsoever.the phones will connect to the network and look like it's always connected to the network but will not load any pages or any thing.one off the network, it works fine.thus is the only device that has ever not worked in my network

I have the same issue. I have had the phone for a month with no issues. The last couple of days, I can't stay connected to any wifi either. It has happened on multiple routers in multiple locations.
I have updated my router firmware (although it happens on all wifi routers). I get a connection, then it disconnects, finds the wifi again, and reconnects...over and over again.
Something is up.
Did a factory reset...wiped everything to start over again...didn't help.

Help with WI-FI. Can't connect to 5 GHz at all.

Hello Everyone.
I've got a problem with my WI-FI in my V20 that doesn't allow me to connect to 5GHz at all.
I'm in the UK with a virgin media super hub 2, I also tested it with a TP-Link C2 which is the one upstairs and nothing still. I know it's not my router as I have about 6 other devices which connects to 5GHz perfectly fine, so I know It's a problem with this device.
I have done everything I can think of to try and get it to work as well. I removed all security from the router. I tested it with another router. I used a WI-FI analyzer to see if the device picks anything up but unfortunately it doesn't find anything at all while my PC next to it can pick up 4 to 5. I also changed the channels of the WI-FI and still nothing except that it seen a few high frequencies which I couldn't connect to and the few that I did it doesn't connect to the internet at all. I've also reset the device, and updated the firmware. Still nothing has worked.
This is my 2nd V20 as my first one had the WI-FI problem as well and I hoped I just unlucky with that one and the replacement had exactly the same problem.
I brought it from ebay by the name of eglobalcentral-gb. They quickly got in contact and everything. Perfect communication. The 2nd device was also from this person as well.
The phone is also the H990DS duel sim version.
Thanks Ben
