Nexus 4 ruins my home wi-fi !?

Every time i connect nexus 4 to my home wi-fi. Every other device gets terrible connection speed... Before nexus 4 my Nexus 7 had steady speeds up to 20mbps. With nexus 4 connected speeds go down to 5-3 mbps and even when i disconnect n4 from my home wi-fi router still acts really strange and i have to reboot it. Anybody experienced anything like that?

I have three desktop computers, an iPad, an iPod, a Roku unit, and two smartphones sharing the same wifi signal. My speeds don't seem to vary any regardless of the number of devices sharing it at any given time. I would have to call my service provider if I found myself in your situation.

Yep, same.
To the op, I'd say either reboot the router (which you probably have done) and / or see if there's a firmware update for the router.
If no cure, call your internet provider.

Ok.. Forgot to mentioned that n4 also loses wifi connection from time to time.
Seems like im not the only one.. People post similar problems.

my nexus has never dropped wifi connection to any router you may have hardware issues..

I have seen this before. It happens in mixed networks (old B laptop used to crash the WiFi AP when G clients were also connected).
1) Check for a firmware update to your router. This is most likely where your issue is. The router speed should drop and increase as needed, but buggy firmware may only keep in last slowest speed until a reboot.
2) Mixed encryption (WPA & WPA2) is a nightmare Force "WPA2 only with AES only" -or- "WPA only with TKIP only". Some clients may try to use WPA with AES and this was what was crashing my AP at the time.
3) If you still have issues, try using "G&N" only, or even force G only. Some older G clients don't hear N traffic, so they just transmit on top of it.
4) Last resort, look for a used router that can run DD-WRT firmware. Personally, I will never go back to OEM router firmware.
Hope this helps...

i used Wi-Fi Analyzer and it showed 2 really strong signals on the same channel.. one being mine and the other someone's else. i manually changed it from 11 to channel 5 and everything back to normal/// 20mbps just like before!

Hi every one. I just got my N4 last week and i experiense the exact same thing!!!!
this is realy bad because every time i use the wireless network every body in the house starts complaining because my N4 shuts down all connections here.
It works alright with the main router wich is a thomson. but it fails with the other two routers (that are Belkin - N) that are only access points!
I realy want this fixed because not having internet at home is quite bad!

I had the same problem, repeated on two different GS4 phones today. I tried everything possible to figure out what was wrong but couldn't fix the problem. The phones would connect to my wireless router, but would send and receive data only intermittently. Sometimes, resetting the router, or pulling the phone's battery, or going into airplane mode would be the only ways to get the phone to actually send and receive data, but it would only work for 20 seconds - 3 minutes. Every other wireless device and wired device works on this router, except for the GS4. And the GS4s both worked in-store on their wireless network. My guess is that it's a hardware or software compatibility issue with certain routers. Oh and mobile data worked like a charm.
What kind of wireless router do you have?

Maybe you need to pay your internet bill

My S4 has the exact same problem on a DLink 655. Works ok on other networks I have tried but on the DLink it will work for about 20 seconds and then data stops flowing. No other device I have has any issues.

To figure out whether the issues is the SGS4 or the SGS4<>your router you really need to try it from some different locations. The i9100 had tons of issues with D-Link routers so perhaps that's what's happening here. My solution when I had issues with my i9100 was to ditch D-Link forever and move to NetGear and I haven't had a problem since (at least at home).

Hey guys my at&t S4 16 gig is having the same problems. For me it connects to my d-link 615 for about 2 or three minutes then times out. I have to turn wifi back off and on again for my wifi to kick back on. I'll do some more testing on other routers to make sure its not my s4. Hope its my dlink. If so ill get a none dlink router. Frustration as all hell.. I even connected using pin code and still the same any suggestions guys Thanks. Really don't want to return phone. Thanks

My router is a DIR-655 as well. Looks like this may be an actual issue with D-Link routers? Anybody having issues with another brand of router?
And if it IS an issue with D-Link, who's at fault for the problem? Samsung or D-Link? My 655 has been the most reliable piece of network equipment I've ever owned. It works with everything, except for a Galaxy S4...this is annoying.

glad i still have my unlimited data plan. no real reason to click the wifi button... most wifi spots i go near are more bogged down & slower than the s4 lol

yeah i actually got my phone 2 days ago and right out of the box had this problem, i was on other sites saying that the s3 i900 had alot of those issues on 4.2 and 4.2.1 jellybean.. lots of users reporting that when the upgraded to 4.2 ect they started having those issues.. i hope its a jellybean issue not hardware issue.. i agree with you though i have had my d-link 655 for years and never had an issue till now.. i have my s3 and iphone 5 all running on my dlink just fine S4 not so much..

Same problem here - excelent connection at 150 Mbps with my dlink dir-855, but dies quickly. wifi toggle helps. Tried a lot of settings, fixed ip/dhcp, 2.4 / 5 Ghz and etc - problem persists.

i have TP-LINK router but i drained my battery till phone went off then charged till 100% and no issues so far wifi works fine... just wondering why this problem could appear...

Seems like I've found the solution - in router settings, in firewall section disabled "TCP Endpoint Filtering" (set from "Address Restricted" to "Endpoint Independent"). Have not had any issues since than. But can't actually tell if it puts the network to any risk compared to previous settings.

i have also different problem
everything seems good but i have a big problem with wi fi but
when i try it with s2, it is working
whenever i want to access internet with wi fi on s4, in Wi fi menu, it writes -----> in order
1) "Obtaining ip adress..." and later
2)saved,secured
3)Obtaining ip adress...
4)failed to obtain ip
5)newtwork disabled becauseinternet connection is low
my modem's security is WPA*Wpa2 psk
and my modem model is

Samsung galaxy s4 wifi issues
I have the same problem, seems to be a wifi issue with 4.2.2, my router is DIR 655 Dlink, wifi only works if I just connected it then its either slow or disconnects. very frustrating, also I get 3G but its slow.

A family member just got a S4 and is facing the same issue with the DIR655.
I've updated firmware to latest version for my A4 hardware model, version 1.35ww but the problem persists. So I had to bring out another Access Point (TP-Link TL-MR3020)to cater to his needs...
So who should we complain to? the DLink has been serving me faithfully for the past 3 years+, infact the DIR655 was one of the best wireless routers around and I never an issue with any of my wireless toys, until it met the S4...

Can you confirm that this fix works for a lengthy period of time? Is it still working? I thought I had fixed mine once (the phone was working for a while) and then it just stopped transferring data altogether. I think tinkering around with some things can make it better or worse, depending on what it is.

Same here. I was contemplating replacing my 655 after 6 years of service without ever having to reset it only because it will not pass magic packets from WAN to LAN...at least the A versions don't (I have A2). And this is becoming more of a frequent problem as of late. Every other device connects without issue, even my mom's S2. I'm on WiFi right now on my HTC Vivid...no problems.
Which brings me to this...everybody in this thread with a 655, please list your hardware version and firmware version. It can be found at the top of the router's web interface page.
Mine is..
Hardware Version: A2
Firmware Version: 1.34NA

WiFi disconnecting issue

Well this is weird, my new note is now disconnecting from my WiFi router after a short period of inactivity. This just started a couple days ago (just before this new 2nd firmware update). I'm not sure how long it takes to happen, but it's somewhere close to an hour. When I find my tablet disconnected, the notifications tell me that there are networks available in one notification and that my crudentials timed out in another. It will not automatically reconnect to my router either, so I have to go and reconnect to it manually each time...and it's a pain in the yang.
The odd thing is, it remembers the WiFi password, so it's not like it completely dumped the settings. So in theory, it should reconnect automatically since it still remembers the network and password.
It could just be my router, but my SIII and my laptop have never had this issue. I checked the settings to see if I was in power save mode or anything...but I'm not.
Any suggestions appreciated.

Well, I have tried restarting the tablet and the router...both to no avail.
This is getting frusterating now. I simply watched an epsiode of the Walking Dead and it killed my connection while doing that...WTF? It also did it later while my tablet was downloading a bunch of updates, so a few of those updates didn't download because the connection died after a while.
Why would it do this even when the tablet and the connection are active?

I am having the same issue, but it isn't my Note dropping the connection, it is my router rebooting.
Next time it happens, log into your router and check on the router uptime to see if it just reset.
What router do you have?
Mine is a D-Link DIR-655

I have the same router, but it's not doing what yours is doing (my uptime has been for over a week it says). But that does make me wonder if it is still an issue with the router...
I have been searching and some of the other samsung devices that had issues and some of them (that didn't require root) were fixed by setting the DHCP release time to 2 days (instead of holding it forever) and/or setting the ip to a static one on their phones. I plan on trying this next and letting you all know how it goes.

Yay! So the fix was to set a static IP on my tablet...that's it. My router was already set to release DHCP every 24 hours, so I didn't change any settings there. Before I did this, my connection was dropping about every 15 minutes. After setting the static IP, I let it sit for an hour and it's still holding strong.

Did you set a static IP directly on the tablet, or did you set a reserved IP on the router?

I set the static IP directly on the tablet and I have not had an issue since doing this.

Maybe you can restore your tablet to solve this problem.

does it happen on other wireless networks? what security are you using? wep/wpa?
try changing the security to see if that helps. odd that a static ip fixes it. its almost like it loses its ip configuration.
when your tablet looses network, are you actively using it, or was it in sleep mode?

The tablet would lose connection while actively using it...it was weird.
What's even weirder is that I have NOT set other WiFi connections to static IPs like I had to do with my D-Link router, yet the connections with those other routers have remained steady while in default DHCP modes. I have no idea why this would be the case (it doesn't make sense).
Like I said earlier, my router does not have very much in the way of special settings...just WPA 2, N-only mode, and a DHCP IP release after 24 hours of inactivity are the only options I enforced. Looking at my router logs, it definitely sees my tablet and updates the release time each time I use the tablet...but I don't see anything in the logs when the tablet suddenly disconnects from the router. So I have no idea if it's the router or the tablet. lol
I have not tried another security setting, but I don't want to lessen my security in this environment. Beseides, I know at least one othe router that I connect to is using WPA2 also.
I can live with this work-around as long as I don't have to force a static IP on every other router I connect to.

I have a different model dlink (dap2553) and I have the random disconnects also. I see wifi connected normally but no data flows. Eventually the connection drops and reestablishes fine for a while..before it all happens again.
Has the static ip solved this for everyone?
Tablet works fine on all other wifi aps and all other devices work fine on my ap

I also have a DLink router (DGL 4500), mind you, it's an utter piece of crap and I plan on replacing it with an Asus ac66u sooner or later. I also have this issue where it will show connected but no data will flow for a few seconds and then everything will be fine again. Static IP hasn't really solved much for me. I'm hoping that this indeed is a router issue so I can continue to use this in peace when I replace this DLink junk.

Static IP has not solved it for me. I have been using my travel router at home which does not reset.

change the channel on your router. the channel you're on may be saturated. i've got 3 routers with no problems:
1 belkin n300+ share - stock firmware
1 asus n56u - padavan firmware
1 asus ac66r - merlin
all steady.

Same problem. Just got it today and close to returning it. Factory reset and static IP didn't help.
Wasted 90 minutes trying different things. It's just bad hardware. I even installed Kies and let it re-image the whole thing to MK1 again (very very slowly). Just sitting at the intial setup where you pick the wifi you want to connect to i can watch it disconnect and reconnect over and over. Returning it in the morning.

I'm also getting annoyed with the wifi problem

I'm having this problem too and it's really starting to annoy me. It didn't happen when I first bought it but now I have to re - enable wifi at least 10 times a day. Wifi will turn itself off when I'm using the tablet or when the screen is off, when it happens seems to be somewhat random but it won't happen again for at least 10 minutes after I've re-enabled wifi. I have tried everything but a factory reset...

You guys either have bad wifi/router or have defective devices. Minehas been perfect.

I'm on my 4th Note 10.1 2014. All of them had this issue with a bunch of different routers/configurations.

with four acting up it's quite possible that your routers and configurations are the problem. the note may just be picky mofo and you need to tweak you wifi set up. if you don't feel like fidgeting with your network, just give up and get something that plays well with you set up. when you've got limited free time network tweaking is not oneof the fun things on my list, lol.

Wifi issue related to root?

Hi Folks,
I have been postponing this post but nothing ive seemed to do has worked. I THINK after i rooted my issues started. I am unable to browse the net or anything when connected to my wifi. I have reset the router, forgotten and rejoined the network with no avail. All my other devices do not have this issue. Im not really sure what else to say so maybe some of you gurus could pick my brain. Though this is a wifi only issue and on this network. When connected to other networks im fine. My setup is as follows. I have a hard line going from the router the ISP provided in the other end of the house to the router in my room. Like i said my phone is the only device that has issues on this network.
thanks in advance.

That's a pretty strange issue, not sure there is going to be much help... I've had some strange, random issues with my S5. I had issues with wireless, xposed and some other apps after rooting the first time. I got tired of it and used Odin to reflash the stock firmware, then performed a factory reset and rooted afterwords. I haven't had any problems at all after doing this... In all honesty, that's the route I would go if I were you. Sorry I couldn't be more helpful, hope you get sorted out

Can you reset the settings in the router via your pc?

Try connecting standing right next to the router. I had this issue with my Note 2 and it ended up being a physical issue with the wireless chip or antennas. It's actually the reason I'm not on a S5.

Not that u want to hear this, but I had to replace my router for the same reason. My router would only pick up certain devices, had to do with hardware and firewall security settings.

First and foremost you have to isolate the issue to either ur phone or the router. In order to do that its very simple.... can you connect to wifi outside of your house like starbucks or friends wfii? If the answer is yes than the issue lies solely with your router. Let me know what you find out and I can help guide you <---- systems administrator Also please provide the make and model of your router as well as your modem and your ISP.
EDIT: I just read the line where you talk about having another router in your room. I can already tell you this is probably NOT an issue with your phone but rather your setup. The secondary router must be setup as a repeater or bridge OR on a different subnet. This gets very tricky for average home user and I do not recommend you tackle it on your own. Also your main router has to be able to play nice with the secondary and if it's one provided by your ISP it's probably a POS. Also your phone is probably not the only device having issues with this setup.... its the only one you are noticing having issues. Android OS is very sensitive to weird wifi setups and anything out of the norm will set it off. It's actually a great tool in diagnosing wifi issues.

Hi there thanks for the reply. Yes i can connect to any other router without issue. The router is my Router Info:
Name N300 Wireless Router
Model F9K1002v5 (01B)
Firmware 5.00.15(Nov 1 2013)
Serial No. 12349GC2508237
Boot Loader 0.12
I use my tablet and other pcs within this wifi. It is under a different subnet as well. (i think so been a while since ive done any networking) The main router that comes in has the standard IP 192.168.1.1 and the IP for my router in my room (basically set up like this since my room is quite far and gets bad signal from the main router, Cable in -> Main Router -> Hardwire hooked into a port -> ethernet run to my room -> Connected to a port on the wireless router) 192.168.2.1. My ISP is Optimumn Online. My wifi was working fine until about 10 mins ago. seems to happen so often. I did change the security a while back to TKIP + AES on the router and made sure it was the same on the phone and it was working fine for days until like i said about 10 mins ago.

This leads me to think that perhaps the router (however old or new) may have a setting, or an actual limit, on how many devices connect to it.
If not that, perhaps if you rooted, and tried removing bloat, you may have been a bit overzealous and removed something related to WiFi and are now having this issue as a result.
I have only removed the list of apps and bloat that have been posted on Ricks Rom HERE. The ONLY problem I have seen since removing this list, was that I can no longer access PhotoVault correctly. Gives me an error saying that it has no connection to the database, but my 4G is working fine at the time as I was downloading via steam and streaming a movie, and playing a PC game at the same time...

I did change the security a while back to TKIP + AES on the router and made sure it was the same on the phone and it was working fine for days until like i said about 10 mins ago.

You have the right setup with a different subnet. It's possible the main router is assigning the same IP address that your router has to another device. It would be best if you picked up another router that has repeater capabilities and set it up in repeater mode. Also reserve an IP address for your router from the main router to avoid IP conflicts.
Another possibility is simply the wifi on your router is deteriorating and it's time for a replacement. I recommend the Netgear Nighthawk R7000 if you don't mind spending the $$$. If your on a bit of a budget the Netgear N900 (WNDR4500v2) is the next best thing that supports repeater mode.

well its been still working intermediary. I have to unplug the router and plug it back in then i can browse the net on my phone. idk if id like to lay out that kind of money for a new router. there has to be something else thats causing it. i set the router to reboot everyday, also my phone. its odd though. sometimes it works sometimes it dosent.

S8 Internet connection may not be available issue

Just got the S8 and I have 3 Wi-Fi access points at home to cover the whole house. My S8 has been registered with the passwords for all of the APs but it continually rejects the connections with an exclamation mark after the WiFi icon having connected and then shown a message that the Internet connection may not be available. The Internet connection is available as other devices are connected and using it perfectly. If I switch the Wi-Fi on and off and reboot the S8 the issue corrects itself but I should not have to go through that nonsense every time I come home and want to use my Wi-Fi. I have explored the advanced options on the connection settings and they appear to be quite limited (DHCP Etc). Is there some way to solve this issue? I have no problem with other android devices connecting to the same hotspots. Any ideas that might lead to a solution would be appreciated.

I had this problem when i first got my s8 from vodafone but when i got this latest update it's been good no issues with internet anymore.

I have this problem as well with my S8 from Verizon. Worked flawlessly for a week and them today I get this error. Very frustrating. I know the SMG955U from Verizon is already unlocked but is there any way to put the International ROM on the phone seeing that the Verizon and the International are the same?
I've tried all the resets etc and the WiFi connects but I get the 'Internet connection may not be available' message.

Update 27/04/2017
Thanks for the reply. My S8 developed some interesting issues including the switching on of 'do not disturb' mode intermittently and along with the Wi-Fi issue the mobile data was failing in areas where a full 4G signal was present. Rebooting, resetting etc did not resolve the issue and I returned the phone to CPW for advice. The staff at the Glasgow store wasted no time and exchanged it on the spot after some negotiation with their technical service centre. Full marks to CPW for the prompt service and I can report that all of the previous issues have now been resolved with the replacement handset. I thought it worthwhile to post this information so that others who experience similar issues may be able to get a similar resolution.

Poor WIFI performance
I also have issues with the wifi of the phone, /i will get the terminal replace some time today or next week.
1. WIFI keeps disconnecting, actually it's flapping connct&disconnect for 5-10 min until it finally connects, on this matter I have seen on the acces point that it tried to allocate an ip from an unknown without asking DHCP server for an IP renew it actually tries to alocate itself the last known ip, and clearly disconnects because of lack of internet access, this happens normally as power saving mode is on, disabeling power saving and assigning a static ip on the phone seems to resolve the issue.
2. poor wifi signal... no fix for this thus far
- i have 580Mbps speed connection on my S5 and only 120-240Mbps on my S8, steaming not working and connection in general very bad, time ots and stuf, although I position myself at 10cm away from the wifi router antenas i only get 540Mbps signal, although I have an AC1750 router , s5 gets 840 in the same spot... I think the modem(that is part of the Exynos chipset) does not work wekll with Atheros based AP´s , I have an Archer C7 with 2.4ghz QCA9558 chipset capable of 450 Mbps theoretical speed, but only uses 2 antenas as s8 only has 2 from my knowledge and reaches a max of 140Mbps(should of connected at 300Mbps at 10cm in theory ) with the s8 and QCA9880-BR4A on the 5ghz side of things with a theoretical speed of 1300Mbps should work at 866 with the S8 because of the 2 antenas of the S8.

phone changed 90% of problems fixed
Hello, just got my phone replaced, tha new unit has way better wifi signal considering I hace atheros router and the phone has broadcom 43xx chipset... worth considerign changing to a broadcom router...

Hi,
I have found a solution to this problem.
1. GO to wifi settings
2. Forget the wifi network
3. CONNECT AGAIN BUT BEFORE CONNECTING GO TO ADVANCED OPTIONS AND CHOOSE STATIC INSTEAD OF AUtOMATIC. Enter in the ip address etc and connect.( It requires to be entered manually) Problem will be solved.

Change the DNS...
Hi there..
I had just the same problem with s8 plus and s7 edge(after updating to android 7.0), it kept saying "internet may not be available", I changed the DNS to 8.8.8.8 and tue problem solved. Go to SETTINGS》WIFI》SSID》MANGE NETWORK》change the IP SETTINGS to STATIC》then change the DNS1 to 8.8.8.8 hit save and you are good to go.
Sorry if there are any mistakes. I am new to XDA and not good in english.

I have same problem and it is very annoying. I got 2 S8 plus and both have the problem.
There are 3 WIFI Router that covers my house. I have problems saying internet might not be available every time I connect. This is very annoying. Other Phones in the house like Iphone do not have the problem.
What I noticed is that the IP range of my router is:
192.168.1.1
But my S8 says he is connected but the IP is
192.168.0.100
Anyone have same problem?
Thanks!

I found a quick work around on how to fix this temporarily until Samsung issues a patch.
just turn off 5ghz SSID broadcasting and you should be ok for now.
here is a quick how to video i made on just in case.
https://youtu.be/Nu5FjDPLn-M

I'm having a very similar problem with my home WiFi and my Verizon S8+ I bought from Samsung's website. I've tried switching from DHCP to static and entering all my info. No luck. I've also switched my dns1 to 8.8.8.8 and dns2 to 8.8.4.4, and my WiFi router is set to 2.4ghz only. No success in resolving the issue. Currently my phone will show the "internet may not be available" with the added exclaimation point for a few minutes when first connected, then the exclaimation goes away and I'll have regular full speed internet for around 25-45 seconds before it goes back to a non-internet state. Any suggestions?

Try changing in your router the security setting. If your using WPA2 AES/TKIP, change to just WPA2 TKIP and see if this works for you...
I was having the same exact issue for months. I changed to TKIP only and have been rock solid ever since. No more ! at all... I'm gonna switch to just AES today and see how that works.

Changed to WPA2-AES and within the hour had ! back and no internet. Went back to TKIP and rock solid again. Looks like a possible bug with AES to me. Sticking with wpa2-tkip setting for now.

I'm having this same exact issue.
Anyone who knows what to look for to fix this, what info or files do you need from me? I'm at the end of my tether with this ****

I am having the exact same issue on my galaxy tab s2, even on the replacement. Due to the being such an intermittent problem, it wouldn't do it when Samsung support checked it out...
This happens on both 2.4 ghz and 5 ghz frequency for me. I've tried downloading a wifi fixer, I've reset network settings, and turned off nearby device scanning. I've also tried doing what a forum suggested by changing the ip settings from dhcp to static but it wouldn't connect to wifi at all. Not sure what else to try...
I read that it may be due to nougat 7.0 software. I was suggested by Samsung to first put the tablet on safe mode (this disables third party apps, and would reveil if an app was causing the problem) but the problem still persists. Also did a hard reset on the first tablet I had but it still done the same problem...

I always thought that this was a is problem in 7.0, and was addressed in 7.1. Hopefully, when the next major update comes out, this issue will be resolved.

Oh come on Samsung!
It's been 4 months since the first post and still no solution.
And it's a basic wifi connection!
Internet may not be available! = Samsung may not be available

Heya all. First post I guess
Edit: Gah it was the second. I have to controll myself better and not spam.
So I had the same problem and tried more or less all.
My "solution" was to disable the firewall on the router which means some settings/security there was triggered. My guess is that it's the "Smart Network connection" that trigger it if the phone have both poor Wi-Fi and 4G. It then jumps back and forward = firewall detect strange behaviour and block. That's why there are so many strange "fix" related to the router - hidden network - no security - disable 5Ghz and so on.
Can someone please test asap as I have a plan But if it's not this to test
