WiFi disconnects often?

I'm really happy with the phone so far, but my wifi disconnects fairly regularly and I keep getting a force close on the SMCC Process (whatever that is). Anyone else having problems?

I just read the thread below this and that issue seems similar.
EDIT: I tried turning off the smart wifi, but it still loses connection. The phone still shows that it's connected to whatever wifi signal, but stops downloading. This happens both at home and at work, so I don't believe it's related to the router itself.

I'm seeing the same issue on mine as well. Noticed it last night playing Pandora via wifi. Would play like 3 songs then nothing. I would have to toggle wifi on/off to get Pandora playing again.

Sounds like basically the same thing. If I wait long enough, it comes back on its own, but it's faster to just cycle wifi or airplane mode once. It's fairly frustrating, and I even found myself just using 3G to do things last night instead of Wifi.

seems to be a known issue in other S4 forums:

Mixed Mode WIFI
I had this exact same problem with my EVO 4G LTE, the problem was the mixed mode WIFI. (B,G,N). On the EVO it turned out to be an easy fix because there was a setting in the WIFI menu to force either B or G. As soon as I selected one mode I had a solid internet connection. The problem here is there does not seem to be an option in the S4 settings to allow this. I have been trying to force single mode on my router to see if that will fix it but my router will not allow me to turn it off either. Pretty serious bug I would say.

WIFI worthless on brand new S4

it doesn't do it as often as it did with the SGS3 though

I really wish I could find a resolution to this. I'm thinking of wiping my phone and starting over to make sure it isn't an app issue, but man that's a lot of work.

Im having the same issue as well.. Im almost positive its common issue and i would expect it to be addressed in the next OTA

The common link seems to be DLink router. We have a Cisco Linksys router and it stays hooked up solid on that.

I have an Asus router. Don't know if there are usually problems with those or not, but I haven't had any prior issues.

I have a Cisco e4200 stock and a Asus running ddwrt operating as a wireless bridge to extend my network. I had to turn off mixed mode on both devices to resolve the issue. Hope that helps.

I have the same problem but I have Netgear routers. The one at my house works fine, but at my other location. The wifi drops.

Same problem on dlink

Adding my 2 cents because I have 2 S4's that I've been testing with and I'm getting mixed results... my first post here so I hope I'm doing this right!
I have 2 wireless routers at home:
- DLink DIR-655
- One provided by my ISP (Bell Canada; not sure of the model at the moment)
The DIR-655 is troublesome for BOTH S4 devices; they stay connected for a few minutes (or longer in some cases) but will always end up not transferring data even though they show as having a very strong signal. Turning wifi on/off always fixes the issue for a short period of time.
Knowing that there seem to be compatibility issues with the S4 and DLink router, I switched them both over to the Bell router. Now only one of the devices has the wifi issue described above.
I found it odd that changing the router being used fixed the issue for one of the devices but not the other. I'm now questioning whether one device has a hardware issue or not (doubtful on this, but worth questioning).
Both S4's have the most up-to-date firmware as do all of the routers in the house. No other devices (iPhones, laptops, apple tv, etc...) have any issues with the wifi.
I've tried resetting the routers, forgetting the wifi connection and setting it back up, rebooting the phone, smashing my head against the wall; nothing seems to have worked permanently.
Is it possible that this is a hardware issue and not a software issue? Has anyone else had similar results with multiple devices?

fix....?
this wifi drops are due to the router WIFI signal setting. it will drop it you are using a B/G Mixed signal/ B/G/N Mixed signal. i recommend setting it on 802.11 g. or, if all your Devices in the house have N use N since it has more bandwidth. i use G because of the PS3
Hope this helps resolve the issue for you guys, it sure did for me.

Thanks for the suggestion, I can attest that this wasn't a permanent solution for me. After switching to N mode only, the amount of times the issue occurred was reduced, but still happens at least once per day.
It's also a pain when I'm connected to networks where I have no control over the wireless settings (work, public networks, friends networks).

I have a linksys modem and router. Haven't had a single connection issue with this phone as I had with my EVO. As my wifi disconnects and reconnects right away. Lol. First time that has happened. Knocked on wood.

[Q] Kit Kat Wifi Issues

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?

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!

5 Ghz connectivity fix

The Nexus Player has one of the oddest bugs when it comes to connectivity. In its' current state it will NOT recognize three digit channels on the 5Ghz band. The upshot of this is:
it might appear to connect, but then drop to 2.4Ghz sporadically before reconnecting @ 5Ghz. This will happen when you have your router channel set to "automatic". Sooner or later it will automatically choose a higher channel (100+) and therefore become invisible to the Nexus player.
in order to see the 5Ghz band from the NP, you need to set your router to fixed channel for 5Ghz on a 2-digit channel (40 in my case). Believe me, it works just fine then...
We'd prefer automatic channel selection in the router obviously, but at least the mystery is solved.
sidenote: as of writing, Android M still also has this issue. It's not a lollipop thing.
sidenote 2: 2.4Ghz is unaffected by any of this

Thanks! You solved my problem

It's the DFS and radar channels on the 5 GHz band which the Nexus Player does not connect to. Channels 149 through 161 do work with this device, however.

Ah, someone got to the bottom of this ! Having talked to Google support (hugely keen to help, but it was an unknown bug to them at that point) it was just surprising that it wasn't even acknowledged as an issue before.
Then again, I must confess all this DFS/radar channel commercial etc stuff is alien to me (and should be irrelevant to consumers)

The DFS / radar stuff is explained in the Q&A at http://superuser.com/questions/692835/which-5ghz-channel-to-use.

Just for completeness' sake: As already mentioned in another tread, this has been fixed permanently with the Marshmallow update and the Nexus Player can now connect to the 5GHz DFS channels perfectly.
At least I haven't had any problems at all in that department after the update. Even those random disconnects that I got on the non-DFS channels are gone now and the Nexus Player stays connected all of the time. This is what I've been hoping for and I'm glad to see that Google seems to have fixed all Wi-Fi issues within this device (I wasn't too optimistic to be honest).
Might be that somebody else could still be facing issues, but mine have all been fixed with 6.0.

It doesn't appear to be working well for me at all on 5ghz. I am on marshmellow. I first figured out I had WiFi problem when I tried to stream games with moonlight and they would lag and give poor connection pop-up all the time.
I then dled a WiFi speed app and it shows its not working properly. On auto, which defaulted to channel 149, I got around 50Mbits/s down 200Mbits/s up. I then saw this thread hoping it would fixing muy problem, so I switched to channel 40 and now I'm getting 20Mbits/s down 200 Mbits/s up. Everyone other device in my house is getting above 200Mbits/s down.
I'll try playing with some more channels. I'd appreciate some suggestions if you have any.
I really don't get it. It's saying my link speed is higher than 500mbits/s.

I'm getting double the amount of downstream: 98mbit/s (that is on channel 104).
But only 19 mbit/s up.

I kind of figured it out. It appears mine simply has terrible reception (although it shows 4 bars). I moved it to maybe a couple of feet from my router and finally got speeds consistently above 100Mbits/s and sometimes above 200Mbits/s. This is a great router and gives me speeds to devices in every corner of the house 200Mbits/s+, so it's really strange the Nexus Player cannot attain it.
Edit: picked up another for $25 at target and it has the same issues. Next my router my fire phone is getting 400Mbits/s. Both of these still only get 100-200 next to the router and 40-60 where I want it.

Nexus Player Wifi

Hello, I own 2 nexus players, suddenly 2 days ago after working well, both started to develop slow wifi connections, streaming is nearly impossible, I downloaded a web browser for the device and opened a speed test page, the maximum speed registered is no more than 1.5 mbps while my internet connection is 10 mbps, all my other wireless devices get at least 9.8 mbps when tested the connection, strangely in the nexus playerthe speed increases a little more during the morning at the most to 3 mbps. I tried everything regarding the router, at first I used my dsl router wifi then I turned it of and started using my airport extreme, no changes in my nexus players, and getting full speed in my other devices, then I connected the nexus players to the airportextreme 5ghz wifi network, no change, I also tried to get the router closer to the nexus player, no change.
The last thing I tried is to share my mobile 4g connection to the nexus player which is about 25 mbps, I was standing next to the nexus player and the fastest speed it got was 1.5 mbps.
The problem occur in both nexus players, my other wireless devices get full wifi network speed, I dont know what else to do. Is this a common known issue?

How far away are they from the router? I have my router and NP #1 in the same room, and 5ghz signal is excellent. But the signal for NP #2 in the bedroom is lousy, so it uses the 2.4ghz band.
Maybe try using a wifi analyzer app to see what the best channels are for your router?

The router is at the most 15 feet from the nexus player. The strange thing is that both worked fine for about 3 months and suddenly at the same time they presented this problem. Could it maybe a firmware update? Mmmm When I shared my 4g connection I was three feet from the nexus player, I have no further ideas of what could be the problem. Neither google nor asus have responded my emails.

most likely a driver incompatibility issue that came with the latest update.
I assume this to be the case since I used to have wifi problems with the Nexus player in the past, which used to disconnect from my wifi sometimes, especially with my 5GHz wifi, to which it never managed to stay connected more than a few days in a row. And all of those problems are gone after the new update. So I assume that the changes fixed things for some people (like me) and broke things for others (like you). My speed from the Nexus Player is blazing fast as well, it maxes out my connection when performing a speed test.

If it is happend right after I have updated to 6.0 I will understand but three weeks later....
Somewhere I read that NP can be connected with wlan cabel using wlan adapter.If is it possible do you think it will solve the problem?

It should solve the problem. Also I've heard wlan cables come cheap these days on ebay.

Maybe a neighbor is now using a bad channel. See adjacent channel interference and co-channel interference.

Apparently my dsl modem blacklisted both nexus players, i don't know why, so the bandwidth for the two devices was limited. What i did was to reset the modem, problem solved temporarily, I already had to reseted it twice, as it blacklisted the np again. After doing that the speed in my nexus players is back to nearly 10 mbps again.

WiFi issues?

I previously had an Asus ac1900 with no issues on my S8 but upgraded to a TP-Link Deco mesh. I've been having tons of issues whenever all 3 mesh units are plugged in only on my S8. All other devices operate fine. On my S8, literally every few minutes, I get the exclamation mark and lose internet but have full WiFi signal. Sometimes it repairs itself and other times I have to cycle WiFi. An Honor 8 right next to my S8 at the same time has no issues. If I unplug 2 of the mesh units, obviously I lose coverage but the S8 is completely stable. I've tried all the WiFi settings on the phone. Anyone else or any ideas?

Sometimes it repairs itself and other times I have to cycle WiFi. An Honor 8 right next to my S8 at the same time has no issues.

1) Have you tried to connect to 2.4 GHz and 5 GHz networks?
2) Forget the connection and re-connect again.
It might be that phone doesn't hop from one router to the other or has a hard time deciding which access point it wants to connect. I have a regular Netgear router, but a good one, so no issues.
Check if your router has a firmware update - helps sometimes.

No firmware update and no control over bands with any of the new mesh routers

Bump

I have the same problem too on my S8+. Hopefully this will get addressed.

I have the Deco mesh router and have the same issues. None of my other devices have problems, just the S8. So frustrating!

Try this if you haven't done so already... I was having the exact same issue. I changed the wpa/wpa2 setting from AES/tkip to just wpa/wpa2 tkip only and haven't gotten any more disconnects on mine. I was Rock solid last night and usually lose internet connection multiple times a night. I had found that in another forum so I thought I'd mention it here.
I may go back and try AES by itself tonight to see how it acts. AES is the more secure method.

You cant do this on the new mesh routers

I'm having the same problem with my Asus RT-AC66U router; I'll try changing the WPA setting tonight. My Pixel never had any issues with that router though.
I've got an unlocked US model S8.
Anybody have issues with Google WiFi? I was considering picking up a 3-pack...

Didn't know that. I'm using the Comcast cable modem/router and also Linksys E3200.

Last week, I upgrade my home router from Netgear AC1750 to TP-Link Deco M5 and experience the same thing. Both S8 phones lost the internet and with a notification of "Internet may not be available". That is when WiFi still connected. I even change the phone Wifi IPv4 to static IP instead of DHCP and DNS server point to 8.8.8.8 and 8.8.4.4, still the phone lost the internet connection once in awhile at home with the new TP-Link Mesh type router. It appears that the Wifi issue is worst or only with the Mesh type wifi system. None of the other devices at home have this issue including the old S6 phones.

I have the Orbi 3200AC and I was having the same problem with an S8 I picked up from Craigslist. Did a bunch of tests on it and Verizon ended up sending me a replacement for it and this one has been good. No idea what set it off.

Solved!
I have an AC1900 and having the same issues on the my Galaxy S8+, disconnecting frequently. Switched to Tkip security but the speed is limited to the 56Mbps. so I get the logs and see that somehow the router is detecting my phone traffic as DoS attacks. I disabled Port Scan and DoS Protection option on the the WAN setup!!! and it worked!!
