does other phone work well when you are far in the router?
I have two router in the house and i use extender when im working far from my first router because in our house we need to use an extender so that the signal can be transmit to a much fardest location. Like forexample there is a big wall between the first router and your position
or have you tried to restart your router/modem as well?

Other devices work well with the router in my house.
The problem is with the note 3 ...
In my work it is the same, only works near the router
It must be about 30 cm from the router to work
this sucks

Hmm that is very strange
The WiFi antenna in your note 3 might have broken / come loose.
I think there is a way to test this as i'm sure that Bluetooth also uses the wifi antenna you could try doing this to clarify this as i'm trying to help you out but i don't have too much knowledge on the internal components.
Turn Bluetooth on on your note 3 and connect to a Bluetooth device like a speaker and see how far the connection reaches .
But it sounds almost entirely that you have a faulty WI-FI antenna in your note 3 its usually easy to get this repaired and shouldn't cost you a ton of dosh

Try to connect my bluetooth note 3 other device and the same thing happens with wiifi.
Only it works being close.
I think it is hardware problem

What router is it? I assume you've tried 2.4ghz as the range is much better than 5ghz.

I perform the test with different ranges and routers get the same result.
I tested 5 different routers.

Question for those who use WiFi on their X1

How far from the WiFi HotSpot can your X1 get before the connection is useless? I'm in a house and it barely works in the next room (newer house, walls made of drywall). My brother has an iPod Touch that works all over the house perfectly (same router). I'm wondering if there is something wrong with the WiFi radio on my X1?
i get v good coverage from the x1 as good as the iphone. try changing your radio firmware
WhyBe,
Is it set to best performance or best battery?
Go under settings to check.
Cheers.
Doesn't it depend on the HotSpot itself ?- I mean on the router, its signal strength and etc...I connect to my router trough 2 brick + concrete walls and have no problems at all...Always connected in every room

same , even good outside/inside the neighbours house ,
be sure to have the 1.15 or 1.16 radio (or smthing like that , the new ones)
+what poisonwolf said
and dont buy a metal case for ur phone
also helps if i slide open the phone for me ... and its good to face the router too (not with ur back towards it)

I can always connect to my router from the door on the street (I live on the first floor) and everywhere in the house including the bedroo with router being on the corridor outside.
And I did not tweak anything in my EnergyROM 3.0
Thanks all. I have never specifically changed my radio firmware. Is this something that is updated when I change ROMs? I've went from R1a to R2a to R3a. Does the radio get changed with these?
I have the X1 set to best performance.
It depends on what kind of router you have. The cheap ones are crappy. I have a medium spec one and I get good connectivity through 3 walls.
I have a LinkSys G router. It is pretty common. Everything I use works fine with it (3 laptops and iPod Touch). Only the X1 can see it but not connect.

Did you see the settings in the phone that allow you to use better Wi-Fi reception, but get poor battery life? I had problems with Wi-Fi until I set it to "better performance" rather than "better battery life".
Yes, it is set to best performance. My X1 recognizes the router but doesn't connect. I'm wondering if there is some other problem?
EDIT: OK, I just discovered that if I turn off the phone radio, the WiFi works properly. Is it supposed to be this way?
with linksys and all other routers really one have to upgrade the firmware once in awhile
to get best support with newer devices

Nope. There is a problem. I have no idea what it could be though . Maybe an update is a good thought.
I only use stock ROMs and haven't really tweaked my system beyond factory state. So I don't see why I need to update anything. I'm thinking there is some sort of conflict between my internet settings for the phone and the internet settings for the WiFi connection?

Mine did that when I 1st tried to set it up, it would find the network (hidden) ok, but would not connect. No matter what I tried, even though 2 pc's (wired), laptop (wireless), xbox (wired) & iPod touch (wireless) were working fine.
I gave up on the X1 and turned my attention to the router, tried a static IP for the X1 etc (it's back on DCHP now), after rebooting the router, the X1 connected and worked fine and it has ever since. I have no idea why - but initially it would not connect - something funny with the router.
I have a netgear router and every now and then kicks me off. i have to disable my wifi on the x1 and reconnect or even power off the router and back on for it to work.
Turn off your router for 1 minute and power back on then try to reconnect your x1.
I have a Linksys WRT160N router and it actually doesn't even detect it when it transmits mixed speed, only of I put it on B and G it detects it.
Otherwise the signal is average, a bit worse then my laptop.

I only use Wi-Fi at my university. Well basically my Wi-Fi works everywhere around campus, at the dorms, and at the movie theater right next to school.
It's freaking great, but I prefer 3G. I just can't afford it.

Wifi Possibly broken

HI
last night i rooted my phone using the exploid x10 root apk, at first it worked fine and so i left is plugged in over night to transfer all my music onto my new sd card
but this morning it seems the wifi has broken
it connects to the network but will not send or receive data, so the browser says no connection, so does the market etc
i have reflashed its software 3 times even downgraded back to the R1, still no luck, its not even rooted and its broken
any1 had the same issue? i have searched the forum but the ppl with the sam issue have not been helped. please i dont want to spend $$ to get it fixed i have no job
Hi.
No problem with the wifi so far.This is strange.
Do you have warranty?
Sound stupid but did you try to reset your router?
If nothing is working you should go to the service.
yea i messed around with wifi router, nothing, i can browse the net on 3g wich is odd, but 3g is expensive so that cnt be the solution. bluetooth and 3g work obv but the wifi cannot connect itl connect to the wirelss just NO datac exchange?
There is someone with the same kind of problem but on an EVO 4g, but i really do not understand what they reply's mean. Maybe you do?
http://forum.xda-developers.com/showthread.php?t=800910
tried to search on google and came across a LOT of people having this same issue, on laptops, iphones, ipads, which lead to the conclusion that it may not be a wifi failure?
well it cant be a complete wifi failure kuz i used the dev menu and it says wlam enabled and scanning just no connection
thanks

+1 and so much more for all your help man
i managed to fix it, it wasnt my device as such it was my router, too so i fiddled around with both mainly giving my x10 a static ip and bam it worked, cheers!!
I too have a wifi problem, but it is quiet a different one and i have no idea how to solve it.
when I connect to wifi at home my router reboots, but there is no such problem when i connect to my office.
I tried reseting the router at home and still no use, once it got connected and when i started a download from the market the router again rebooted.
How can i solve this????

Tried diffrent encryptions? like WPA2 or WEP?
Maybe switch from G to N standard (or vise versa, if availible?)

And your router obviously operates all 3 standards at once

SGS1/SGS2 Wifi connects but no Internet data transfer

I was wondering if anyone else have the same issue, I tried on my galaxys ,galaxy s2 and even on my galaxy tab 10.1 wifi could connect but there is no data transfer, I have tried this on several routers in my office but the result is same, is this a bug on android or hardware problem?
I have tried static IP, change many things but no chance, I even tried on different kernels but...

most likely your office has blocked access through mobile devices

Yes I have the same prob, goes steady for ten mins, then just stops receiving a network connection, but my desire is fine. My honeycomb tablet does the same thing, but just turning wifi on and off fixes it. This appears to need a full reboot then works perfect again for a while. I've only had this phone two hours and have noticed it so surely others have.

I too faced the similar problem in the beginning dude...later some where in the forum one user stated to reduce the security level of modem or router from WPA/WPA2 to WEP/AES...then it works flawless...i don't know whether it is a problem with android or hardware...but most of the router or modem is secured with higher level of security which could not be accessed by our SGS2..i hope this would be fixed by software update..

Its is most likely router specific problem as its not a general problem and the majority have no problem with the highest security level .

It seems to be a problem with just some devices as indicated by this thread: http://forum.xda-developers.com/showthread.php?t=1194635. For a high end smartphone worth £500, temperamental wifi is a problem i shouldn't have to put up with. My router has no problem with any other devices so it's clearly a fault with the phone.
Never had an issue with wifi and wpa / wpa2 on multiple hot spots and home. Try a factor reset and flash . On kf3 xeu

http://tweakker.com/wizard/step1
That tweaker site is for GPRS/3g connection, this thread is about WIFI connection, so it won't help.
I have wifi problems as well. It connects just fine when i first configured the network but it won't work back from standby, although it still looks connected it won't transfer any data. Today i noticed an extra detail, it would seem that an app that was connected was still working but anything else i started fresh (like openinng the browser to access a page) wouldn't work.
I also noticed it loosing connection once after using it continuously for around 15 minutes.
Still haven't tried changing the security settings on the router, but, i previously had an ipad2 (for a short time, then sold it because it's just an expensive toy) and it would display the same behaviour.
Before that, i had a Nexus S with the same router and it always worked flawlessly! No settings were changed in the router.
I'm going to try lowering the security to wpa or wep and test it later.
If it works it might be a problem with the router but it's also a problem with the device (phone/ipad).
EDIT: one more thing, when i first got the SGS2 it had an older rom (vodafone KE7 i think) and it worked flawlessly until i updated it to a newer version the next day. I can't be to sure this was the culprit because i didn't use it that much the day before and it was a fresh install so maybe the issue didn't have time to show up.
one of my friends has a captivate sgs he also has the same problem, seems to be an android bug, or maybe samsung, another issue on this phone is about the bluetooth , it can not discover my headset bluetooth (sony DR-BT50) I have tried galaxy s , galaxy s2 and galaxy tab 10.1 but none of them can discover the headphone seems my galaxy life is messed up
Well i had similar issues with my vibrant and even on my nexus one....i think it is android bug....but if u r using cm7 or miui...u can easily get rid of it...by going to wifi settings>>>>advanced settings>>>regulatory domain>>>>change it to 14 channels....
but my sgs2 doesnt have this prob so far....i used those settings on nexus one and vibrant....and it worked....
Hope this helps..

Surely it would be backwards compatible.
It should be meaningless if bluetooth 3 not support BT2.x many devices still using BT2.X, anyhow my laptop is bt2 but I can connect to my sgs or sgs2

My Glalaxy s 2 has the same problem. It was fine till i was on KF7 but things changed with KG6 now.
My SGSII connects fine to every WiFi I've tried to join (open and ones that I know the password for). That is at least 3 different models of D-Link routers, a few Belkin and others that I can't recall.
I don't count a connection until I can actually view the internet and live stream the radio and I have been on it for more than an hour (I was proving to an ipad & ipad2 users that there was nothing wrong with a WiFi router and it was their toys that kept on dropping the connection).
I am was using the E7 and now F3 stock ROMs.
I did have a problem for about half a day. It would say connected to the WiFi but I couldn't get to the internet. I had to switch off the WiFi and connect via data connection and then try again with the WiFi - sometimes it would work sometimes it didn't. The only thing I installed prior to the problem was the Twitter app (from the market). Once I uninstalled that app and rebooted the phone everything was working fine. I can't say for definite that it was the cause of the problem.
To the OP: since you are connected to the work's WiFi, could the problem with not seeing the internet be due to the Work using a proxy server. That is what my work has.

Well I have a router that was supplied by imagine.ie, its a Motorola router and they with-hold the password to change settings on the router, have you heard the like????
Anyway trying that twitter suggestion, maybe the sync function was causing intermitttent wifi problems
Edit: Scrap them not giving out passwords http://www.imagine.ie/wimax_hub_setup.html
After a few hours survey I could connect my phone to the wifi, but Im not sure if this method works for you, anyhow I will explain here check it on your phone and report back
-Downaload the application "wifi static" from the market and install
-turn your wifi on and then run the application
-in the application choose add configuration,a window will popup saying have found a wifi connection will ask you to set for this connection or no just accept
-exit the application and turn off wifi
-turn on wifi and try to connect to internet,if you can connect then you are done if you can not go to below
-go to wifi static and choose the configuration which is already set and change the DNS I changed DNS1 to 8.8.8.8 and DNS2 8.8.4.4
-reboot (maybe not neccessary but recommended to do)
-turn on wifi and connect to internet and check if you still can not then...
-wait for me for further study

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

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...

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.

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

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

[Q] Wifi won't stay connected.

Is anyone else having issues with Wifi not staying connected? For example, it'll keep dropping out from my router every 3 minutes or so. When it drops out, the 3G will enable for a few seconds but then it will connect back to the router.
Is anyone else having this issue? What did you do to fix it?
Cheers
Are you rooted? Have you done any mods? Perhaps you should check the advanced settings in the WiFi option

Hi,
No I'm not rooted. No mods at all. 100% stock firmware. I have checked the Advanced Wifi options but can't see anything wrong.
Just to mention, I did at first think it might have been a fault with the phone so I got the phone swapped out with another brand new device however the problem still persists.
I have a similar problem on a i9505 running the latest CM 10.2 nightly.
Some 2.4GHz networks are fine, others behave as you describe.
The one 5GHz network to which I have access has recently started to misbehave; the phone connects properly and works for about 2 minutes, after which I lose all connectivity (I can't even ping the router) yet the wifi indicator remains blue. Turning wifi off and on again gives me another 2 minutes. This goes on until I give up and switch to 2.4GHz.
Of course, I have no idea what is causing this. I've tried various channels on the router, as well as rebooting it.
Does this happen to all routers (I assume you use other routers somewhere else), or it just happen to this router only? Is this case, you may want to check the router itself.

Frequent disconnections occur on all 2.4GHz networks. As for the 5GHz, I've only got access to one router on which to test it.

I've only tested it on my router.
As I say, I thought the phone was faulty so I swapped it out but the one I swapped it out with had the exact same issue.

A couple of things concern me about this method though. Do we know what setting that mode to OFF actually does? I've heard reports that the phone gets quite hot and battery drains.

Well I got my phone swapped out (3rd one now) and I'll see how it goes.
Ni !^^ what us Your Android version ans MoDem actually? If you have that it s probable due to that i think..
Or maybe Your are a doesntt support Very well Your fréquences for match Your mobile?
Have you try to make a Fullwipe? For put tint everything restant as when you have buy it?
You will be on a custom rom with ni mldem update i dont say but chère..
WiFi still disconnecting even on 3rd device...
Wiping /system and flashing a newer nightly fixed the 2.4 GHz problem, but 5GHz is still dodgy. It's not the (Netgear) router as I have a couple of other Cyanogenmod devices which operate without any problem.
Perhaps I should start another thread as this may well be something different from what is affecting the op's device.
