i dont know what does that mean but my modem model is
inca IM-205NX
Does your WIFI have SSID broadcast enabled? I've run into issues with some devices when I had that disabled. What about connecting to other access points?

My galaxy s2 is working and also samsung notebook.. but there is a problem in s4..... i really dont know .... what does it cause by?
my wi fi modem's model is "inca IM-205NX" can you google it? i cannot enter a website link on forum because of new user
i have some news i guess i will solve the problem
when i enter my modem surface, i see modem passward.. as i write before, my modem is inca, and security type Wpa/wpa2 psk..
when i change security type from Wpa/wpa2 psk..to non-security, i can access my wi fi connection. i mean if there is no password on modem, i can reach but it can be dangerous, hackers can intrude....
i will change my modem settings until solve wi fi problem and i will notify you
okey the problem has been solved guys....
i have entered my modem's surface and changed Security type from WPA*Wpa2 psk to Wep and restart both devices
Web is not so secure rather than WPA*Wpa2 psk but the important point is that s4 is working with wi fi

This is not a solution. Wep can be cracked in 2 minutes and somebody can style your Internet. Change back to wpa2 psk. Changing to wep isn't the smartest selection

Do you have an option to enter the passcode in hex? Seems I ran across an issue some time in the past where I had to do that. Seemed an odd solution but worked for me at the time.

Try with WPA2 TKIP or even WPA, but no WEP. WPA should work. There seems to be something wrong with your modem. Isn't there any firmware update for it ?

So, you could enter the passcode in hex. There's a small chance this could help. You'd have to do the same on the phone obviously as well. Actually, I just realized I don't have that option on my phone (and old Dinc2) so may not even be an option.

Galaxy S4 WiFi problem too
I dont see why this went to a router issue...?? I am having the same problem with the WiFi on my one day old S4. It is almost like the signal freezes because it still shows I am connected with a strong signal but nothing works. I have never encountered a problem before with any other devices(S2, S3 Note2, multple tablets) and saying that it is a router issue and saying that i have to disable security or get a new router is not a solution!
I have seen this same post on multiple forums and yahoo answers but nothing as far as a real answer to the issue or to what is causing the problem. PS...there are two new S4's in the house and both having the same issue....
I'm having the same problem, Brazilian S4, at my girlfriend's house, I could not connect to Wifi, the modem is a Fiberhome HG110-B.
Same issues here unfortunately. I think it's the router. Wifi at work is fine. Wifi at home has issues. That's a bummer because I love my Amped Wireless Router at home.
Same issue
Hi Guys,
So my S4 is also just a day old, and I am having the same issue, tried everything, only connects when I remove my wifi security(obviously not ideal), I am brand new to Android, jumped ship from Apple .
I dont have then exact model number with me now(at work) but my router is a trendNET something something 335.
All my other devices connect to my wireless without issues accept my S4, it is very annoying, we are still being screwed over by our Mobile Operators in South Africa, hence the fact that my wireless is so important to me..
Thanks for the help!
actually we have to wait for new update... hopefully samsung will solve that problem...
i am now using with low securtiy (wep) but i don have any choice now
My fix
My FIX
Hey dudes and chicks,
I used to have this problem too with my s4. Connecting just a minute or two and after it would just lose connection. At first i thought it had to do with something from the hardware, but i figured that was not the problem since it did have a stable wifi connection at my uni.
So the problem for most of the people is within the router. Here's how i solved it for me. (I have a Sitecom Wireless Media Router 300N WL-350 with 2.4 and 5 ghz, so the steps might differ a bit if you have different router)
-------------------------------------
1. Login to your router
2. Go to the setting for wireless 2.4 (probably radio 1) (For Sitecom go to tab Basic> subtab Wireless 2.4 GHz)
So what i changed here is the 802.11 mode. (there are several modes like: just 802.11b, just 802.11g, just 802.11n, mixed 802.11b and 802.11g, mixed 802.11g and 802.11n ........)
>>> I Put It On: "mixed 802.11g and 802.11n"<<< (it used to be on mixed 802.11b, 802.11g and 802.11n)
3. Secondly i disabled Auto Channel Scan. This allowed me to select a Wireless Channel (frequency/channel).
>>>I Chose the highest channel ("2.472 GHz - CH13")<<<
4. I used to have the Transmission Rate at the option "best (automatically)"
>>>I changed this to the option: "54" (Mbit/s)<<<
5. I have channel width at the option: "auto 20/40 MHz" (but it always used to be this one)
Furthermore i have the following settings:
> Security mode: "WPA - Personal"
> WPA Mode: "WPA or WPA2"
> Cipher Type: "TKIP and AES"
------------------------------------
Now running stable for more than 6 hours (incl heavy use like youtube and movie streaming from samba server). I believe that step 2, 3 and 4 are the most important ones. If this does not work immediately, try to play a bit with step 3 and 4
Im not that technical but if you have questions feel free to ask.
Help out your fellow Galaxy mate by letting them know whether this worked or not ;-p
Ill also post my fix at this thread http://forum.xda-developers.com/showthread.php?t=2253471
Greetings,
ps sorry if i made some grammer mistakes, not my native language
Hi you all, I'm new here, so please be patient with me.
I have a weird problem with my (just bought) Landrover Discovery (Spreadtrum SC8810 1.0GHz Cortex A5) phone.
I con't figure out wether its a hardware or software issue, so I'm asking some advice after searching the various posts.
The phone notifies me that there are Wi-Fi networks available, but when I go into the Wi-Fi settings, it doesn't show any SSID's, so its impossible to connect to a network. See attachment.
Can anyone help me out?
Best regards,
Fedor
Hello
It could be normal, if the admin of the wifi network switched off his Wifi network's SSID broadcast. In this case You need to know the correct SSID name to set up the wifi connection. Other case You can't connect to this network.
Of course if Your phone never see any wifi network may be it is a software or hardware bug, but if it happened only one place, where this hidden SSID is reachable, You need to know the name of the SSID correctly.
Laca
Push Menu, then scan.
Thanks for the replies. Please only reply after understanding my question and looking at the attachment.
I've never heard of a problem like this before...but do you ever see any SSIDs? Like at home, Starbucks, ect.
Sent from my LePanII using xda app-developers app
This is either a hidden SSID for security purposes then you should ask for the proper SSID name before connecting else you wont be able to see it even if you scan.....
Like I stated earlier, please only offer sugestions AFTER understanding my question and LOOKING at the attachment. As you can see in the attachment, I have 2 phones next to each other. The Samsung shows plenty of SSID's and the Chinese phone shows none. So wether or not there are hidden networks, is not the issue.
The Chinese phone notifies me that there are available networks (which it should, as there are!), but the SSID's don't show up. Very strange. In other words: it detects the available networks, but doesn't show which ones. So I can't select one to connect to.
My guess is that it has to be a software issue and not a problem with the hardware.
Could there be a code that I can type in, so I can deeper into the WIFI settings?
What android version is each phone running assuming its a software issue?

I would hope most people would have tried that long before coming to the forum to complain about the issue.
The issue is WiFI closing & not auto signing back in whether mobile data is on or not.
It's simple option is in settings wifi
Yes the switch is simple but has nothing to do with the "closing WiFi" issue some are experiencing.
BUT I DO NOT KNOW Enabling this option AS MANY PEOPLE WHO HAVE THE FOLLOWING HAVE SOLVED MY GUIDE

unchecking this doesnt do nothing....im sitting across from my router and its telling me my signal is weak.
Browsing on vzw 4g lte is faster than my 50mb comcast wifi connection? lol if i browse with wifi its a slow lag.
Same for me. Moreover, with the new firmware, if it loose the connection while the option is unticked, it says that it will be re-ticked automatically...
This WiFi bug is really annoying.
My phone has stopped dropping the connection & is behaving well. But I have no idea what solved it. I factory reset router & phone. But it made little difference but after a day it's behaving perfectly & it's currently on my wifi & has not dropped for 12 hrs & no more constant pop up messages.
I have no idea what cured it. But one thing I did last night was went to play store & updated every app on the phone.... maybe there was a conflict in one of those apps.. that's all I can think. I left "adblock" off this time as that routes wifi data but I'd removed that several days ago.

I'm curious what Access Point you are using and how old it is? Are there firmware updates for it that you have not applied?
I've read somewhere that cancel all existing WiFi connections and make them as new (with the new firmware), could be of help. I'll give it a try.

Wifi problem
I've tried all the solutions on here,and nothing works. Very poor samsung for such an expensive device. If a £30 roku box can have perfect wifi why can't a £600 device
I must admit that wifi performance is quite poor for the moment.
I get 6 or 7 Mb/s out of a 25 Mb connection. My S4 , Note 1, and Ipad 3 al do around 20Mb/s while testing simultaneously

You can probably find what it does on the Internet (Google), but it doesn't truly help. My guess is that these performance issues are router dependant. I'm waiting to get my hands on the new Asus RT-AC68U router to upgrade my yesteryear 300 mb/s router. In fact I just ordered it, it will arrive tomorrow. Will post here to let people know if it helped...

Well I was right, my shaky Wifi connection using my Sitecom WL-351 router is a thing of the past. Both the 2.4GHz and 5GHz connections through my brand new Asus RT68AC router work excellently!!
What this very probably means is that the Note 3 uses a Wifi chipset that doesn't work all that well with certain other (older model?) router chipsets. The Asus I bought to test this is quite expensive, but I am sure a regular router can work well given it is compatible. What needs to be done is verify (through a Poll or by researching known chipset incompatibility problems) what chipsets and/or routers / brands work well. Unless you expect Samsung to fix this in software, which often is impossible - unless Samsung can force an update of the chipset firmware.

Unfortunately Brand names don't mean compatibility since various models use varying router chipsets.
I just purchased the Samsung Galaxy S5 and I have a Western Digital My Net N750 Router. I have SSID Broadcast Disabled and the S5 won't connect. If I start broadcasting the SSID it has no problems connecting.
I have over 20 other devices that have no problems connecting with the SSID disabled, so I don't understand why the S5 can't do it. Even my 3 year old Samsung Galaxy Nexus has no problems connecting with SSID disabled.
I called Verizon and they said they haven't heard of this problem before and that the phone is defective and to return it for a replacement but I have a feeling I'll have the same problem with the replacement phone. I've searched Google trying to find people with similar problems but I can't find any other posts. Can you please help me! Thanks so much.

Perhaps so, but if you don't you won't know for sure. You can try to get it working, but if you exchange and it still continues to not work, then Verizon has it on the books that you had a defective device, and they can start working on fixing that silly problem.

I was hoping someone with the same phone can test it to see if they have the same issues. I'm going to do a factory reset right now to see what happens for troubleshooting purposes. That's also what Verizon recommended that I do. Then I'm going to Verizon to exchange it. If someone else with the same phone can test it to see if it works on your phone or not I would greatly appreciate it!! Thanks so much!
I wonder if it's a compatibility issue with my router. Maybe I should go try it on someone elses router and not broadcast their SSID and see what happens. That will help me determine if my phones defective, or if it's a compatibility issue, etc.
I'll still do a factory reset and replace the phone if I still have problems to see what those results are too. It would also be helpful if people with the same phone tested it out to see what their results are. Thanks!

Thanks for the information. To help me trouble shoot it did you connect 2.4Ghz or 5Ghz? What's the make & model of your router? I'm trying to figure out if my phone is defective or it'a a compatibility issue with my router. I'm trying to connect 5Ghz so maybe I'll try 2.4Ghz now. I'll also try connecting with someone else's router. Thanks!
Try adding the network manually

I had this same issue. It would happen if I had the SSID broadcasting, connected my S5, then turned off the broadcast on the router. It wouldn't work if the phone had found the network through a scan. I got mine to work (with my Netgear R6250) by adding wireless network manually on the phone. Hope this helps you, too.
Any resolution on this? I have the same issue. Since I'm rooted and happy, I really don't want to return my phone.
Sent from my SM-G900V using XDA Free mobile app
I am aware this reply is over a year later but I am assuming that there may be others this issue is happening to.
I also had the identical problem. When SSID was set to broadcast, the One Plus and Samsung Galaxy S5 would connect without any issues as normal. When the SSID was set not to broadcast, I would have an authentication error and/or show the WiFi connection saved. All this started after the router's f/w and both phones' (Android)OS were updated. This was on both the 2.4GHz and 5GHz frequencies.
Here's the solution - this is done on the phones/mobile units having the connection issues AND having your router's SSID's set not to broadcast.
1) Hold and press the WiFi connection and select "Forget"
You will now more than likely see those available. Make sure you don't use these connections
2) You now have to chose the option to "Add Network" from the menu (One Plus) or "Add Wifi Network" at the bottom of the WiFi settings on the Galaxy S5.
3) Manually type in the SSID you want to connect to, select the type of security and enter the password for your WiFi
4) Repeat steps 2) and 3) if you have a second SSID you want to connect to
5) You should be able to now connect to your Wifi network, if not reboot your phone/mobile device and you should now be able to connect.
Hope this helps you out.

Hi,
My rooted Verizon Samsung Galaxy Note 3 (SM-N900V) running the stock KitKat 4.4.2 stopped connecting to 5GHz 802.11ac AP's. I first noticed it at a friends house, then again at home. I can connect to 2.4GHz 802.11ac, 802.11n & 802.11g just fine. When I try to connect, it says "Connecting" for a second or two, then drops to "Saved, secure" with no other errors or messages. Once it's saved, pressing "Connect" doesn't seem to do anything.
My home AP is a TP-Link Archer C9 running the latest firmware. The 2.4GHz & 5GHz bands have different SSID's. I read about issues with Samsung devices & 5GHz channels so I tried changing it from auto to 44 to 36 to no avail. Note that both of my Samsung Tab S 8.4's and my wife's Note 3 (same model & OS) along with all my laptops can connect to the 5GHz frequency just fine. I run a separate DHCP server and tried manually removing the entry for my Note 3 to no avail.
In the Wifi Advanced settings, I have "Passpoint" off and "Auto network switch" unchecked.
I also read about disable Wifi Power Saving Mode by dialing *#0011# but dialing that only brings me to a Verizon error message.
I tried using the app Wifi Connection Manager to wipe all the wifi connections (the "Fix Wi-Fi Problems" option) but that didn't help.
Next I'll try to see if I can figure out how to use logcat to get some sort of error message.
After many hours of reading about similar issues, I've run out of options to try short of factory wiping which I'd prefer to avoid. I'd be grateful for any other suggestions.
Thanks!

It could simply be a lousy antenna connection or that your 5GHz radio died. I presume you see the 5GHz SSID when searching.. so the radio itself is probably ok.
Take the back off your phone, using s jewlers screwdriver, check the screws around the outside edge on the back if the phone. If any are loose, that can cause reception issues. Do not overtighten! Just make sure they're firm and not loose.

Hi donc113,
Thanks for the reply.
After powering off, I removed the rear cover & battery and made sure all 12 screws were nice and snug but not overtightened. I also loosened and retightened the one next to the SD card slot since some diagrams indicate the wifi antennas are located there. As an aside, do you know what the "L" and "R" labels are next to round buttons on either side of the SD card? I haven't found any documentation on that yet.
Unfortunately, it didn't help. The SSID shows with a strong signal but still won't connect. This might be the issue, though, because the 5GHz SSID drops to no signal every now and then but that's inconsistent.
I'll try to figure out to use logcat to see if I can find an error but let me know if you or anyone else can think of other things to try.
Thanks!

No idea on the buttons, on mine there are are just brown 'fillers' in them.

Ok.. Found the info on the buttons, they are covers for connectors, i presume for testing purposes.

Mine recently had the issue as well (I have an Archer TP-Link C5). After testing wifi and seeing I still used the 5G at work, hard and soft rebooting my Ubiquity Uni-Fi AC AP, and even double checking with the WiFi Analyzer app, I finally went into the router to check if maybe the MAC was no longer registered. Ultimately, I thought to just unbind the phone and re-enable it. I only got as far as to unbind the IP (there is a checkbox in 'IP & MAC Binding' -> 'Binding Settings') and suddenly it connected and is working again. So, if you happen to have bound a static IP to the MAC address, uncheck that box and it magically works again. The IP stays the same between connections so I guess it is not super important.
Just an idea.
EDIT:
Okay, turns out the issue resolves around the fact that you have a conflicting IP address on your network and the phone software decides to disable the connection rather than obtain a new IP. I found the best way to resolve this is to set all my major devices with an address assignment on the network (you can find this under DHCP -> Address Reservation).
So, though related, the above issue turned out only a temporary fix. My phone was trying to get the same IP as my Ubiquity AP despite the MAC binding for the AP.
