So i have a week old galaxy S4 and everything is fine until i realise that it only sees and connects to my 2.4Ghz SSID. I use a dual-band sitecom WL-309 extreme gaming router. My laptop, ipad and galaxy tab can scan and connect to the 5Ghz SSID. I'm really surprised that a phone that boasts 802.11ac isn't even able to see 5ghz wifi. i recently installed the wifi analyzer app, and it doesn't help, can only still see 2.4.
I recently upgraded my firmware to the indian MEA stock ROM. Dunno if anyone out there has experienced this, help apprectiated.
Thanks
I saw in a post that wifi channel may be the problem, my router has the following 5ghz channel options: auto,36,40,44 and 48. Just tried all and still no joy.
im having the same problem exaclly.
i cant see any 5Ghz network at all.
i tried replacing channels on my router and still. cant see.
With 4.2.2 I had no issues with wifi and can still go back to that version and have no issues, but with version 4.3 and 4.4 I have had and still have the following problem.
I have a list of known wifi connection points as well as available access points. Everything appears as it should, but the wifi will not automatically connect to any wifi (protected or unprotected/known or previously unknown) without first turning the wifi off and back on. Additionally, this only works if the persistent background wifi option is toggled off. If I do toggle the wifi on and off and connect to an available access point everything is fine so long as I remain in range and stay connected. If I go out of range and lose the connection, when I next reenter the range and the access point shows up on the list it will not connect unless wifi is cycled on and off. This happens every single day at work and home, although there is a workaround, it is quite annoying to have to cycle the wifi off and on. The networks will show as available and if I click on them and try to force it to connect, it still won't work unless I cycle on and off.
I have seen prior threads with this issue on 4.3 and there was a topic in the official Google issues page and was frankly hoping desperately that 4.4 would fix it, but alas, it has not. I know it is not the device itself since reverting back to 4.2.2 solves the problem.
Does anyone know of a permanent fix to this wifi issue that doesn't involve reverting to an older version of android or some kludged together solution?
Ya.. I have also been facing this problem since i have installed KitKat 4.4 on my i9300
Are you stock? Maybe try another ROM? I had the exact same problem, but my problem was my wifi AP.
1- My router was setup for a/b/g/n, I set it to only what I really had using the Wifi AP, which was g/n
2- I had a weird cable modem to router to Wifi AP setup. The router was handing out IPs, not the Wifi AP. I removed the router and only let the Wifi AP give IP addresses (DHCP). It seemed like the "further hops" away that the DHCP addresses were, the more issues i had with my Android connection.
No other devices on my network had these issues, but doing the above made a world of difference.
All that made my connections lightening quick, no issues at all since then.
odd Wifi behaviour
I got a refurbished delivered N10 last evening, came with 4.2.2, played with it a little, did a network benchmark test (FTP off a LAN NAS) and was getting comparable peformance to my other fastest system (a Thinkpad Ubuntu laptop). It seemed stable but I only used it for like an hour as 4.2.2. I was getting FTP of max 4MB/s over a N-router.
I then let it OTA to 4.3 and then played with it for some hours. Issue I found was the Wifi would work and then have "authentication problem" I had to turn Wifi off then on to make it connect to router. I've had that issue with other devices at times. I was thinking of staying on 4.3 to allow 4.4 to have another bugfix (its not been long out on N10) but I had a key issue for me (PPP Widget didn't work) so I did a stock 4.4. flash upgrade.
On 4.4. the Wifi speed is still fast, but periodically it just stops working, a glitch.
One key thing that stands out is the N10 is connecting at much higher Mbit speeds than any other of my devices, it is showing 130Mbits vs say 20-65Mbits on other devices. I'm wondering if my N10 is "too good" for my router an old low-spec refurbished model (Cisco E1200 v2, which I flashed to latest DD-WRT) ?
I'm not so far disappointed with network performance, just network stability, but I can't tell for sure if its the N10's fault or my router's fault. I'll play with settings a while til I find something stable.
When I first got my N10 I had a lot of trouble with wifi connection. Mostly authentication issues, or it would authenticate but not have internet access. It was frustrating, and Google's support was clueless.
I then tried using wireless tether from my N4 and it worked as it should. The issue ended up being the Arris router that Time Warner uses. I bought a Linksys router and have had 0 issues since. So if you're using an Arris router, or it shares the same chipset, that might be the issue.
The router is the Arris DG860.

Good anecdote.
Well in our house, the proliferation of gadgets has changed progressively to a large number, I make it 14 devices from an initial 2 devices 5 years ago. I count 4 wired and my 4 devices, my son's 2 and my daughter's 3 and my wife's 1. They all compete for router bandwidth, Wifi spectrum, router CPU / cache.
What I might do with this high-performance (capability and demand N10) is segment my network using an old G router I hard fix to non-overlapping channels from N-router, and connect the low-spec devices to the G and high-spec to the N. That will involve no $ and naturally reduce congestion. I run a NAS and download media to it and then stream to gadgets off NAS so I'm Wifi-limited often more than Internet-limited, and even tweaking I get 2MB-4MByte (16Mbit~32Mbit) off a NAS is making my typical LAN speed the same as the Internet bandwidth I buy (16Mbit).
My NEtbook (EEE 1015PN) if it ever felt a Wifi hiccup it would lock-out that frequency and so not see the router til I powered off netbook and remove battery.
I do wonder if some of the N10 Wifi complaints are really just generic or bad combinations with router or "straw that broke the camel's back".
I'm having wifi issues with my N10 as well. I had a few wifi issues at work, but not at home while using 4.3. Now with 4.4 I'm having serious wifi connection issues both at work and at home. In fact my N5 running 4.4.1 is having issues connecting to wifi both at work and at home. Not as often as my N10, but it still happens. I'm running stock on both and have no problem connecting to either network with my laptop.
I've installed wifi fixer, but so far it doesn't seem to be helping much. Does anyone have any suggestions on what might be done to fix this that doesn't involve rooting either device?
I'm now running 4.4.2, and I'm experiencing better wifi connectivity, but it still drops out more than it did on version 4.3. Is anyone else having this issue?

I'm in the same boat, more drops in 4.4.2 than on 4.3 and I'm running stock
same here...waiting for a fix
experiment with the router

Some of your problems might be just coincidence, something changed in your area around the same time as you upgraded. Some of these are just the wrinkles of firmware of device vs firmware of router, some combinations work bad and isn't really "fault" of Android in that you can't test every combination. You could wait for a fix from Android... or just try to avoid the wrinkle by changing settings on the router. A common thing is to move the router from auto to fixed channel and fix to 20mhz narrow. Go the place you mostly are with the N10 and use a Wifi analyser to find the least-congested channel and then set the router to that. What that does is reduce channel-hopping and gives less opportunity for firmware issues on both router and the Android device.
I also had a problem with my N7 when I moved house. The answer was to flash DD-WRT on my router and the problems went away.
So either wait+complain or go look at your router now.
Right now I have DD-WRT on an old refurbished Cisco E1200 and I set it to channel 3 with 20mhz and I got very good Wifi performance. With the stock Cisco firmware I was getting Android Wifi drops and poor performance. Yes, that's partly Android's fault but I fixed it myself quicker flashing firmware on the router.
I also took opportunity in DD-WRT to setup IPTABLES for a transparent proxy so all the devices in my LAN now share a large harddrive as http cache so e.g. any downloads from Play store for say my N4.... is cached to my N10 so I only ever download anything once.
If you have issues still with the N10, then what I find solves a lot of problem is do a stock flash of 4.4.2, on setup untick all the backup+restore from Google, then manually install and configure yourself to make it "vanilla". That often fixes accumulated wrinkles unique to your history of your device and places to more mainstream with less likely of having a unique problem. I do that on all my Android devices now (N4, N7, N10).
Similar wifi problems here
I've had similar issues with my N10.
I will have fast internet speeds (30+ Mbps) and it will just freeze. I'll be watching youtube and it will start buffering. Doing a speed test on my phone shows the speeds as normal. It makes no difference whether connected to 2.4 GHz or 5 GHz wifi.
I just resolved my WiFi issue this past weekend. Connectivity is rock solid
Here is what I did I.
Purchased my own cable modem/router. New router had updated firmware. time warner cable modem did not.
Change beacon interval from 100 to 20 on router and repeater.
Made sure router was on a less congested channel.
All is rock solid
YMMV

Great! Often just tweaking settings can do wonders. I flashed DD-WRT on mine and it solved a lot of issues on an old low-spec router.
Hey Guys,
I posted this in General section but saw this so I will add this info:
I just want to share what and why I did it. First off I did not have problems with my wifi on 4.2.2 with the Nexus10. the second that I went to Slim Kat and Vanir 4.4.2 I had weak wifi signal at work and at home when my nexus 7 slim kat and my galaxy note 2 Vanir did not. I noticed that RAM was also weird on the nexus 10. Even though it showed 2gb of ram on the specs it was only showing 1099 on 4.4.2 when I show that I have 1647 ram available with 4.2.2.
Concerning the OS using Ram. Google said that they would make Kit Kat more RAM friendly but I was using 535mb of RAM for 4.4.2 and right now I am showing only 357.3 mb for 4.2.2. I am using the same apps launchers and screen savers
I just flashed back to 4.2.2 this morning so I will update later, I do see an improvement in the wifi though.
I just want to say that I love Slim Kat and that is why I am on the 4.2.2 I just think Google somehow hosed up the wifi on the Nexus 10.
B][/B] Ok so I am at work and have went back and forth between 4.4.2 and 4.2.2. the 4.4.2 connects and disconnects back and forth. When it does connect to router but it says poor connection and it is only 24mbps. "It drops way more than connected" I am 45 ft from router in an open environment.
The 4.2.2 Slim Kat has a fair connection with 78 Mbps and has not dropped once. So I don't know what the difference is with Kit Kat compared to Jelly Bean but for my nexus 10 my wifi is great now with Jelly Bean. I wish I could figure out why and fix but I do not know programming.
I also installed on both 4.4.2 and 4.2.2 a app called WiFi Connection Fixer *Root* by ZEXTR. It did not help 4.4.2 but it did help with 4.2.2. this app helps connect to poor connections or when Android says avoided poor connection.
I don't know why the Nexus 10 is having issues with wifi with KitKat but I wish I could fix it. So I will be on 4.2.2 until a new version comes out and I will test it to see if it fixed it.
update; I have used 4.2.2 all day with the wifi connection fixer and I have not dropped wifi once and the download speed is fast. It is much faster than what 4.4.2 was, at least on my tablet.

Nexus 10 4.4.3 WiFi Bottleneck Problem
Hello there everyone,
I just wanted to confirm that I personally found a fix on my end for my Nexus 10 WiFi bandwidth problem that was definitely evident for many people that upgraded from 4.4.2. First off, I'm totally stock. I will most likely root & ROM this thing in this near future. I was having a bottleneck on my Nexus 10 around ~2 mbps when I tested using the speedtest.net application (may not be the best measurement application but it works). I ended up fixing the problem by changing my router settings in the WiFi section of my browser based software to N/G Mixed instead of just Mixed (which allows 802.11a/b as well as 802.11g/n to run on the router's WiFi signal). I use DD-WRT on my router as well so that may have played a factor in it but I did NOT see an increase in bandwidth until making the N/G Mixed change in the settings. I found this suggestion earlier in the thread and wanted to give it some credit. Thanks everyone!
I bought a new router a few weeks back for the express purpose of using 5ghz. I set it up and I remember it working at the time, but stopped soon after and I never looked back into it until now,just used the 2.4.
I can see the network, and a few other 5ghz networks in the area, but when I try to connect the signal strength drops and disappears for a few seconds. Looking at 20 ft line of sight.
I've set the router to 20mhz band, used every available channel, and disabled encryption. Nothing so far. Any suggestions?

Not that this helps but my wifes N4 cannot connect to any 5GHz network either, i have tried changing the channels etc. but to no avail.
It used to work brilliantly with 4.2 so the blame lies with Google in the latest updates.
I've searched for your problem and I've found that some channels were missing and google added them in 4.4 update ...what android are you on ?
Stock 4.4.2, nothing i have found works thats for sure.
I am having a similar issue, 2.4ghz signal is full strength but 5ghz struggles to keep one bar whereas my Nexus 7 is full strength on both.
Router is an Asus RT-N66U and I'm running CM11 Snapshot M2 on both devices.
Hi all,
Is anyone having problems connecting to 5ghz bands on their N4?
I reconnected a simultaneous dual-band router that I used while my N4 was on KitKat. It would connect on the 5ghz band without issues, and I could view the 5ghz bands on inSSIDer. I installed the Lollipop factory image and now I cannot view or connect to my router over 5ghz, only 2.4ghz. Setting a different SSID, changing channels and widths does not help.

I'm having the same issue. It doesn't detect any 5 ghz wifi even if I set it to 5 ghz wifi only. I've flashed the factory image a second time thinking that might fix it but it doesn't.
I'm at work now where we have multiple 5ghz networks, and I can't see any of them. Any ideas on what I can do about this? Report a bug somewhere?
I have the the same problem. I've tried high number and low number channels on my Nighthawk using factory firmware default settings.
I solved the issue by reverting to kitkat 4.4.4. I think Google still has some work to do on 5.0.
i've the same problem.... i also thought to revert to KK but dont have the time for it....
i just wish google will fix the 5GHz issue and i wish for black theme (hate this bright white)

i think, the SSID name is the problem?! i'm at work and we have also multiple 5ghz SSIDs. SSIDs without any special character will be shown.
but i have one more problem with wifi. sometimes the phone can't reactivate the wifi module after i used bluetooth in the car. only restart helps
Yeah, I've been having the same issue since upgrading to lollipop.
I remember those issues with one of the older versions of android, but on 4.4.4 all was fine, I could see the networks and connect to them.
Now I no longer see any of the 5Ghz networks.

My nexus 4 (with Lollipop) behaves a bit differently. It does see 5GHz networks when set to 5GHz only, but doesn't see them in automatic mode.
