Wifi won't connect to the Internet

So i have ViperOne 4.1.0 running with Elemental X 10.8 kernel for over a week now. Everything was working fine up until yesterday when suddenly my phone cannot get an external IP address on my Wifi at home anymore. It connects fine to the Wifi itself however it cannot get any internet connection.
I have reset my router, modem, phone and nothing has worked. Other devices in my home which connect to the same wifi get internet connection just fine only my HTC One does not. Mobile data connection works fine btw.
Whats really puzzling to me is that really i have changed nothing on my phone in the last couple of days and not all of a sudden its simply not working so i'm grasping at straws here...
Anybody experiences similar issues or have any ideas what else i could still try to fix this?
Thanks

Well it turns out that changing the Wifi channel on the router from auto (was actually 9) to 11 in my case solved the problem. Weird ****...

Galaxy Note 5 N920W8- Wifi Cuts In And Out

Wicked wakelocks and WiFi issues
Just yesterday I started having wicked WiFi issues, where both 5GHz and 2.4GHz networks would connect, then immediately disconnect, then connect again a few seconds later for it to just do the same thing, over and over. It keeps sending reports everytime it does it. I haven't factory reset though, but I'm going to have to.
Also, I keep getting insane wakelocks. Android OS is the worst, causing 7h+ of wakelocks in a 10h day. Google Play Services is pretty bad too, around 6h+ in that same 10h day.
Anyone else having major issues like this with their Note5? I have the N920W8 model, which I can't really find any info about anywhere

Im having similar wifi issues. Initially trying to connect to my 5ghz N home network (wpa2 psk) connect attempt, drop, connect attempt drop rinse and repeat. After a while it connects and stays connected, however, connecting to any web pages is painfully slow (like a super slow dns lookup), and i frequently get failed web page loading errors or failed to download apps from teh app store. Wifi calling is useless in this state. The same thing happens on an open hotspot network at work (2.4ghz) and the corporate (5ghz n) network. The note will ususally eventually drop wireless and force me back onto LTE. I looked at my data counter after just 3 days, and had used 27gigs of LTE, which is more data than I've used on tmobiles network since last year. Had some spotty wireless issues with teh note 4 rev 3 5.1.1 as well prior, but only had that phone for about 10 days before swapping for teh note 5. Prior to that I had the nexus 6 and no wireless issues on the same networks.

J'ai le même problème avec le 5g damn!!!

Luckily i have a dual dualband router, I set up the alternate AP 2.4ghz N wpa2 psk and the phone appears to be working fine at the moment on that network.

I ended up factory resetting and it appears working for now. A static IP address (DHCP reserved in the router) seemed to help.
Another issue I have though is when disconnecting from WiFi and connecting to mobile data, it seems to have DNS resolution issues until I turn data off and then back on. Not sure if it's the phone or the carrier (Wind Mobile) but it's pretty consistent

Not seeing these issues on my W8.

I'm just having dreadfully slow WiFi on my att model, but it doesn't drop connection

Dial *#0011# and click "wifi settings" from the menu at the top right corner. Turn off power saving mode and restart the phone, see if that does the trick.
If not, google search "note 3 wifi issues" and/or "note 4 wifi issues"and look for answers there. In all likelihood the problems that are being experienced with Wi-Fi on the note 5 are similar to the Wi-Fi issues that the predecessors experience when they launched.

It's Lollipop. It's a known bug in the software since Nov 2014 and Google hasn't addressed it. I too had issues with my WiFi when I first purchased it. But I found the work around. The bug is in the security software. The WpA2-PSK with TKIPS or AES which is a catch all, reeks havoc on our WiFi chips. It doesn't allow the phone to have proper DNS addresses resulting in severely slow internet or dropped connections.
Solution: Change your security standard to WPA/WPA2-PSK without AES or TKIPS.

Is that a phone setting or a router setting?

Hey guys,
I've got an Australian Samsung note 5 that has wifi problems. It started not working all of a sudden so i decided to go along with it but after a while i felt the need to try and make it work again. So i went into recovery mode and factory resetted (thinking that it would help) but then on the boot up after i came to the setup screen and found out that i was screwed. The samsung setup screen doesnt let you go past the setup screen without any wifi. Please help, i wanted to post a thread but im new to this community so i am restricted.
Thanks
p.s wifi networks can be detected but only when the phone is held right next to the router.

I fixed same problem of wifi, its a setting in phone, but you need to root phone, its system setting in system folder.

Any updates on this? Im running one 920g completely stock and another 920g with hybrid n7 port v9. Both have this same issue.

WiFi dropping randomly

None of my devices has ever had dropping problems with the WiFi (iPhone, iPad, S6 Edge+, notebook and a wifi extender). But since I bought the S2, it is randomly dropping connection, with no pattern.

Which model did you buy?

SM-T719
It's the latest 8" with qualcomm

Yes I'm having the same issue in the T713 model but not in the T813 model, both are th Qualcomm model

Im having the same issue with mine. I called samsung support and they were no help.

Same issue with sm-t713

Same issue with SM-T813, found a temporary fix.
Just replaced my SM-T810 with a SM-T813, and ran in same wifi drop issue. My girlfriend and her SM-T813 ran in the same issue too. It happen randomly from 3-4 times per hour to one time in 2 hours. I foud it only occurs on 2.4ghz network connected in N. It happen to me on 3 differents routers, DIR-868L REV B 2.04, DIR-868L Advanded Tomato, DIR-628, and Asus RT-AC68U stock with latest firmware. If i configure the 2.4ghz band to G only, no issue, also, the 5ghz band got no issues at all. Hope this help your issues while waiting for a fix from Samsung.

Thanks for the tip. I can confirm that 5ghz wifi works perfectly. Hopefully samsung will fix soon.

Valid information, ndompierre!!
I´m situated in Germany and bought a S2 8.0 (SM-T710, Android 5.0.2) last week.
One of my use cases is watching movies which are stored on my NAS. With my "old" Nexus 7 (2013) everything worked like a charm.
But with the S2 I ran into the issue that the movies stucked once in a while.
At first I thought it had something to do with the apps I am using, BSPlayer and MX Player Pro (which work fine with the Nexus).
I even downloaded VLC Player but the same behaviour occured.
Then I downloaded the movie locally to my Tab and deactivated WiFi. Bingo..played without any hiccup. Proof enough that everything is fine with the apps.
So I googled a bit and came across this WiFi issue others also have. After I followed your proposal and changed the 2.4GHz band in my router from option "802.11n+b+g" to "802.11b+g" everything works fine again. No dropout during the whole streamed movie.
So I hope, too, that Samsung will come up with a WiFi fix soon.

Interesting. I've noticed that since updating to MM, my T810 seems to frequently switch to my other wifi networks on me. My preferred SSID is 2.4GHz N mode. I never catch it happening when I'm using the tablet, but after going to sleep and waking it up it literally seems always to be on the "wrong" network if I've previously switched it to the "right" one (not sure if it hops off the other 2.4GHz ones as well). I'll stick wiht 5GHz for the time being!

Saw Spotify dropping out a few times this weekend while connected to a wifi Hotspot. Haven't had a chance to test it at home yet. T817W model running Marshmallow.

I bought the T719 LTE 8.0 inch Version last week and also hab wifi connection problems, but only when in airplane mode. My Router is am fritzbox 7490 at 5ghz. Currently without any reason the wifi connection is stable. When in LTE mode the wifi was always stable.

I have the same problem too. (T719 LTE model) I was wondering would the radio mode consume battery faster instead of airplane mode?
P.S. I still have problem but i am on airplane mode. Have not tried yet radio mode

disconnecting wifi
I have the t819 bought it last week constantly dropping wifi had the s3 tablet before never happened also have ipad and does not happen. Sent samsung an email but still waiting for reply

My T813 does this, but only on battery when optimization is on. When it's on the charger, or I turn power optimization off, it stays connected pretty solidly. I suspect a fault in the power management.
It is kind of annoying, as I have some clients that have to be restarted every time the network drops.

How do you turn optimization off? Battery optimization can be turned off on my tablet, but it has to be done app by app (one at a time)

WIFI slow / disconnecting

Hi
I received my 3T yesterday. I am having issues with WIFI
WiFi network drops frequently and the mobile data is used for some time and then WIFI is connected again. See attached .. This happens even when moving between rooms of my house
I think this happens when the mobile wifi changes from 5GHZ to 2.4GHZ when I move away from router
I have updated to OxygenOS 3.5.4 as soon as I received the mobile
The signal strength of the 3T is also very low
I have a 2 year old moto X 2014 and the moto beats the 3T at every place in my house
The signal strength and the wifi speed both are better in moto X
I have checked at various places
I have wiped the cache. Tried changing 2.5GHz to 5GHz
Changed Channels.. Tried all the things that I could find on the internet
But still problems
So is this a hardware problem and should I ask for a replacement? Or is this some Software bug which can be resolved
My router is ASUS RTN66U and a lot of other devices work seamlessly on that router and hence pls dont suggest to change the router
Awaiting replies
Regards

I think this is a bug related to 3.5.4. On 3.5.3 my WiFi worked a lot better, but LTE Advanced is faster on 3.5.4. You can try a custom rom or downgrading, there's also a leaked OxygenOS 4 rom out.

Do you have wifi issues now when u have 3.5.4
I don't want to install new Roms. As I may have to return it in case this is a faulty piece

I'm having the exact same problem. I stream a lot. Very annoying when music video or gaming gets disconnect so often. My Galaxy Note 4, & s6 works fine.

yes, it started on 3.5.4.

here is a screencap of the issue
You can see in the screen cap that the mobile is connected to ASUS5 (5GHZ)
Then as I move away from the router the signal weakens and then the wifi disconnects .. and then it connects to ASUS (2.4GHZ)
Earlier it was connecting to ASUS but with a exclamation mark (without internet).. I waited for 15 minutes but it did not connect
Then I would connect if I switch off and on the wifi toggle
After that I did a factory reset and now you can see the screencap
It connects after a minor delay.. So is this alright
My other mobile - Moto X 2014 simply switches instantly from 5GHz to 2.4GHz and vice versa.. not even half of second is taken on moto x

Give the device a static IP use 2.4 network as it's more of a long range band. I tend to use the 5 band for stationary stuff. My WiFi works fine but all my home devices have a static IP.

This are the things that I did
1) Factory reset
2)Use Legacy DHCP client (under Developer options)
3)Disable Smart Wifi switcher (Advanced Wifi setting)
4)Static IP
This seems to solve the disconnection issue .. I still feel the wifi signal is weak compared to my other devices
Hope this helps someone facing the problem
regards

I had the same Problem on OOS 3.5.3/3.5.4/4.0 at the OnePlus 3T.
I tried every Solution on the internet and nothing worked for me.
But after i looked into my Router-Setup i saw the DHCP Section where i selected 'Renew DHCP every Day'
>>> Screenshot what i mean - imgur.com/KakQX3i.png <<<
After that it works perfect. No connection-issues anymore.

mine is already one day..

I thought it was resolved... but again I noticed slow wifi speeds
thinking of replacement

haven't had the phone long enough to experience disconnects but wifi is definitely slow...
I have a 200mbps connection, getting 160mbps on desktop with LAN cable, 110mbps on my OPO, only 50mbps on my OP3T....
all tested through speedtest with the same server location.
OP3T is chinese version flashed with oxygenos 4.0.1
edit: later tested again with OP3T getting up to 90mbps but still 20 less than the OPO

I have same issus like lajay. The Galaxy S7 from my wife works perfekt in the same Network!

Anyone notices 5GHz WiFi strength issue since updated to Android 10?

I'm not sure if there's only me facing the issue with 5GHz Wifi strength which is often get weak even very close to the router.
So do you find this happening with you?
I don't know if Android 10 causes the issue or just my router goes bad itself.
Please note that my A2 already runs on Android 10 with the latest patch (Jan 5) that released 2-3 days ago.
Thanks

Hello, i had the same problem and a factory reset resolved it.
