I never had problems with my Galaxy note 2 when it came to wifi until I stayed over my mother's house.
My Galaxy Note 2 constantly kept disconnecting, and reconnecting to her router.
I clicked forget network to monitor the signal strength. There was full bars and the signal never got lost.
So I did what a normal user would do. GOOGLE. And I saw A LOT of people experiencing this issue.
Yet there was no solution to the problem! Everyone is hoping to see an update and blah blah.
So I decided to try to figure the problem out myself.
I thought about it. What's different between my mom's optimum wifi vs my Verizon FiOS wifi.
My router has one network name.. Wait my mom has two? Hmmm...
DX20PR.. *disconnects*......... DX20PR 5G *connects*
WALAH! No more disconnecting and reconnecting.
Moral of the Story: If your Galaxy constantly loses wifi signal, check if your router has a '5G' signal, connect to that instead.
Why this works? idfk. But it solved my problem, and hopefully this will solve someone else's problem :good:
If you have AT&T Smart Wifi installed on your phone then that's been known to cause problems also. I had constant wifi connect/disconnect problems until I uninstalled it.
wifi issues set router to use one channel only
I had disconnects a lot as well until I changed my router setting to use only one channel.
I've seen this problem on multiple phones that I've had. A quick restart on the router always fixes it. Lead me to believe it's the router

Make sure you mom's router isn't set to lower then 50 DHCP Address: EX. 192.168.0.50
Sign into the router usually 192.16.0.1 or 192.168.1.1 from web browser. Go to DHCP Setting and make sure you see 192.168.0.XX (XX being the amount of device that can obtain a ip address to get access to internet). If it lower then 20 change to 50 or little higher.
Hope this helps
If my WIFI security is using WPA2 my GN2 will lose internet connectivity after some time of the screen being off. The only way to get it back is by turning off WIFI on my GN2 and turning it back on. I don't have this problem using WEP security in the router. However, using WEP security is less secure and severely limits WIFI speeds (can't use N speeds).
[Updated on 01/29/13]
I just want to provide a follow-up to this. I recently learned about the ARP table in my router which is responsible for mapping the IP address to its MAC address. If my GN2 doesn't access the internet for a certain period of time its IP address is removed from the ARP table and I have to toggle the WIFI on my phone to gain internet access again. I found that manually adding the IP/MAC address of my GN2 to the ARP table solved this problem. In a 24-hour period I've lost internet access 1 time after about 7 hours of inactivity (I was sleeping) and I gained internet access after a few minutes without having to toggle WIFI. I'm only sharing my own personal experience with this issue in the hopes it will help others. Below is the command I used to manually add a static entry into the ARP table of my router (model: Buffalo WZR-HP-G300N, firmware: DD-WRT):
arp -i br0 -s 192.168.0.101 38:AA:3C:85:1F:7C
I have WAP 2 and I don't lose internet connection. Yes I have a small delay when the SN2 wakes up but it connects right away. Go to your wifi setting and hit forget this network and re enter your pass key and see if this might help. You might have another device using the same ip address.

This did the trick for my father-in-law who was in town with is AT&T Galaxy Note II. His wifi kept turning off/on and disconnecting from my router and I couldn't save the network connection. My router is setup with an N network and a B/G network both with WPA2 , and he couldn't connect to either without the issue (everything other wifi device had no problems). I didn't uninstall the "AT&T Smart Wifi" just went into Manage Applications, stopped the services/application it was running and disabled the application. Immediately the phone was able to connect and keep connection with no problems. I didn't need to restart the router or do anything else.

Was starting to have a panic attack at work as it would not connect at all to my WPA2 network and i just bought this phone of craigslist. Your advice of removing that crappy program fixed everything! Thank you!
ok so i searched everywhere for this and couldn't find a solution. i have a note 4 and it will connect to my home wifi just fine. i can search the internet on it, but facebook doesn't load and neither do certain games and the app market loads very very slowly. when i had my S4, it would do everything just fine. i was at my friends house and connected to his wifi and everything loaded lightning fast. so i know it's a problem with my wifi, i just don't know what.
my modem is netgear and my router is belkin AC 1200
any ideas on what to check so i can fix it? i suck up a lot of data lol
Do a speed test on your wifi with another device to determine if it is your phone or your wifi. How does your phone perform on 4g? Does it do the same thing?
the wifi is fine. i can browse the internet, watch netflix, etc. When i'm on my data, everything loads like it normally would.

Try hard resetting you router and before customizing it(changing SSID, encryption, etc...), test it with your phone to see if its any better.
it didn't seem to help. it's dual band and i tried on both. it wouldn't even load the google play until i switched bands.
any other ideas of a possible fix?

Yes.
I just got my VZW Note 4 yesterday and noticed almost the exact same problem. There is a little bit of info out there talking about things like power saving mode and stuff, but I noticed that my speedtest.net throughput was excellent. My next thoughts were DNS resolution or an IPv6 problem. Turns out my wireless router had a default setting with IPv6 routing enabled, but my ISP does not serve IPv6. You may notice the same kind of initial lag on Ubuntu installs (especially with certain VPS providers) where every single command you issue seems to take ages to start, but then completes quickly. I know how to deal with Ubuntu to force a preference for IPv4, but a locked down Samsung phone is a different matter entirely. Thankfully, I was able to just turn it off in the router.
For my specific router (Belkin AC1200 DB), the user interface has an IPv6 settings page, but the options they present to end users isn't intuitive. I changed my 'connection type' on this page to "Local Pass-Through Only", and my problem immediately went away. Have a look and see if you find anything similar.
Thanks, and good luck!

DUDE!! this is exactly what i was looking for. i think this fixed my issue. surfed facebook briefly and it loaded everything instantly. i'll check more as the day goes on. thanks so much man
Fixed My Issue too!
Hey Guys
Newbie here! I just wanted to say that this fixed my problem as well. I don't usually post as you can tell by my info but this was worth coming out of the dark to reply to.
Now to clarify, I too have a Belkin router AC1200 so it may be specific to those. Anyway thanks for the help and enjoy the fish!
someone sticky this! i have the same wifi issue , i am at work right now but i will try it when i get home! , i hope this works!
I am having this same issue bUT Comcast here uses ipv6 as well,I have a Belkin n1 router what do I do?
---------- Post added at 07:39 PM ---------- Previous post was at 06:50 PM ----------
never mind i disable ipv6 in my comcast modem and it seen to do the trick, any idea why this is happening?
I've been having the exact same issue on my Note 4. for the past week or so. Our router/modem is a DPC3941T from Comcast, and I can't seem to find how to turn off IPv6. This setting was under Connections > Local IP Network. If anyone could help instruct me further, you would be a great help. I'm pushing my data cap for the month as it is because of this >.<
I'm having the same problem too. The funny thing is that I went to the Verizon store to see if they could trouble shoot it and the phone did not work on their wifi network either! I realize now how to access my IPv6 settings in my router and that does seem to fix the issue. Unfortunately I cant imagine very many businesses with wifi networks will allow me to reconfigure their router everytime I want to use wifi.....
I started having this issue when I upgraded to lollipop. My Netgear C6300 AC1750 doesn't seem to have an option to disable ipv6 though. Any suggestions?
Hey guys am i the only one having issues with wifi, its so painfully slow takes forever to load a webpage forget about watching a video, and no its not my wifi because i have tried several different ones and its always the same slow speeds, ive gone over my data limit twice since i got the g4 because cant you wifi.
is their a fix for this iissue, love my g4 but seriously thinking about another device

Try the DNSet application - I had painful Comcast WiFi speeds, or lack thereof, and running this application before turning on WiFi solves the issue. Not sure if it's just me, but you should know that MMS doesn't work when the DNSet application is running.
What is stopping us from hardcoding DNS entries in the WLAN config now that we have root? Is this possible?

I looked at it, but the app needs to create a VPN to work, which is a whole other can of worms.
Do you have Comcast? I've learned that Comcast rolled out IPv6 out of nowhere, and many of its routers have issues with some phones (my gf's iphone included). I rooted my phone, disabled IPv6, and now I'm back to consistent 50-80Mbps download speeds on my phone.
Before, I would open up the Speedtest.net app, it would take a full minute or more to locate a server, and then the needle for the download speeds would constantly bounce between 0 and 50, sometimes with my phone prompting me that I lost my internet connection, asking if I would like to switch to data. Worth a shot! If you can't root, DNSet does this for you through the VPN, or you might be able to find a way to shut it off on your router.
I don't seem to have any issues with my phone picking up IPv6 over data or a few other routers, though, so I think this issue is more due to some bad firmware on certain modems.
Yes i do have comcast, their is many other cellphones in my house galaxy s5 ,s6, lg g3, iphone 6, none of them have problems but mine, how do i disable IPv6 once i have root

From the G3 after the 5.0 update, the fix was to disable IPv6 as well. This isn't related to IPv6 though, as it only seems to effect the G3/G4. Also, Google "What is my IP" when on mobile data and you will likely have an IPv6 address from Verizon.
I don't know that it isn't related to ipv6; Samsung phones have similar issues and my girlfriend's iphone does as well. I don't think the problem is the protocol itself, but how certain modems (seemingly Comcast ones) incorrectly implement them in their firmware
Any of you guys having the same issue? Mine started acting up earlier today, LTE works completely fine but can't seem to get WiFi to work at home. WiFi connects just fine, does not show there's no internet or anything. Works for the first 15 seconds I toggle on and off but then nothing afterwards. I have tinkered around with my router settings, including switching to IPv4 as well as activating the option to randomize MAC address on my phone under developer options but to no avail.
Please advise, thanks in advance!
If you are doing that much tinkering then I bet you have done way more tinkering than you have explained.
More than its worth actually unwinding.
If your phone works on all other wifi but yours it is probably your router
If your router works for all devices but your phone your router is fine.
Factory reset your phone.
Dont install try to use it fresh from install if it works then your fine.
Just watch what you tinker with.
If it works it is something you did after the fact.
I've had exactly the same thing start happening to me today. No problems with data over wifi before today, and I haven't made any changes on the router.
All other devices seem to be unaffected when connected to that router, and the phone has the issue whether it's connected to that router or a separate access point (connected back to the same router, so it doesn't completely rule out a router problem.
Edit: It seems that when the problem starts it's only internet traffic that's not getting through - I can still access servers on the local network.

That sounds like a DNS problem, are you using anything that changes dns servers?

It does seem to suggest a DNS problem. I just have Pie's "Private DNS" setting set to Automatic, but I would assume that applies to LTE networks as well as wifi, whereas LTE data is unaffected for me.
As a test, I've set Private DNS to Off now, and I'll see if that solves it.

"Android then sends all DNS queries over a secure channel to this server or marks the network as "No internet access" if it can't reach the server" sounds a bit like what you're experiencing

That's interesting. Setting Private DNS to Off has so far fixed the problem for me. I'm guessing that my mobile network's DNS servers don't support DNS over TLS, which is why LTE wasn't affected with it set to Automatic, and my wifi's DNS provider does support it but is currently broken.

I believe that's the case, I turned off Private DNS and it seems to be working fine now.
Thanks a lot guys! Very interesting.
I'm here with this issue now, I'll turn off private DNS and give it a try, this is driving me mad. thanks everyone!
Edit: been using the device for 30 minutes now with no problems, thanks for the solution!
I'm using a local DNS server (Pi-hole) to block ads and I had to turn off Private DNS, otherwise my phone was also reporting that it had no Internet access.
Private DNS seems to cause issues to many people
Never mind i'm foolish.
Holy crap, thank you guys. This just started happening to me and my wife a few days ago and thought my router was going bad since it was multiple devices. Then I noticed today that my laptop and a few other wireless devices were having absolutely no problems.
On mine it's being caused by the Snapchat update from a few days ago. Avoid Snapchat and WiFi is flawless again, as soon as I open it the WiFi stops working and I have to turn WiFi on and off before it springs to life again. Exactly the same on my eldest's 2xl and youngest's P10 lite.
Hello there,
I am encountering a problem with my beloved N5X...
Since a few weeks it randomly loses connectivity (both cellular and Wi-Fi)
And after a few seconds (sometimes minutes) it catches the network back.
For example:
I wake up the phone for checking messages, and i see WhatsApp saying "searching for messages", no warning icons for network.
Then i try to load a Chrome page, it does not load..
After a few seconds all is getting back to normal and everything loads. (the web page, new messages notifications comes on, etc)
I tried so far:
- Reboot (after a reboot it works normally for a few hours, then problem begins again)
- Resetting network parameters (does nothing)
- Complete factory reset (had 2 weeks problem free then the problem begins again)
- Flashing custom ROM (from Google factory to last Lineage OS 15.1)
For informations:
- No VPN
- No gaming, the phone never heats up
- Good network coverage (both cellular and Wi-Fi)
- No network related apps
- The phone is 3 years old, never felt on the ground
Any ideas?
Thanks a lot for reply, and have a nice day!
I'm having a similar problem since Oreo update, but only on WiFi. On 4G network is working flawlessly but I think is due to carrier network settings on cellular towers.
Every search I made on the web to address the issue finished with a lot of posts read but no decent solution whatsoever, but the other day a reply on reddit made me think and I found a setting on my router WiFi AP section called "Unscheduled APSD (Automatic Power Save Delivery)" and since I disabled it my phone seems working better. I don't know if it's just random luck or it was really the cause of the issue but you can try.
Hope it helps.

Hello,
Thanks for your reply.
I searched everything on the phone that could be wrong and i also ended up that router might be the cause.
I did not found the setting you mention (i'm on Synology router) but i tried to disable the 5 GHz frequency band and use only the 2.4 GHz one.
Since then the phone works perfectly! Although the Wi-Fi speed is a bit slower..
I hope this can help you too!

I was on 2.4Ghz only since a few months but had the issue anyway before disabling uAPSD.
If your bandwidth is reduced is probably because your network is on a "busy" channel, try scanning all the wireless networks around your home (i use wifi analyzer on my phone) and see which are the "busy" channels and set yours on a free one. Bandwidth on 2.4 and 5 ghz should be the same, the pro of the first is a better (wider) coverage of the signal, mostly through walls and the pro of the second is less interference with other wireless technologies and environment at expenses of the coverage.

Well, after a few days i noticed the problem still persist even on 2.4GHz, but less than before..
Unfortunately Synology router does not have APSD option in the Wi-Fi settings.
I tried to put Protected Management Frames (PMF) on "enable - optional", that setting was disabled before.
Wait and see.
Thanks again!
