Loosing internet connection over wifi

hi folks,
this happens both my nexus 7 and galaxy nexus from time to time. While connected to my home wifi they will loose internet connection. They are still connected to my router as i can ping devices on the network. I have to disconnect and reconnect to get net access back again. Im using WPA2 Personal encryption on the routher with tkip/aes
Anyone else experience anything simillar? I have no issues on my work wifi.. it stays connected all the time
Cheers,
Mick

I'm curious about this too. Been having the same problem. I've tried two different routers even went back to stock. I use shout cast on winamp when I sleep. Wakes me up when the music stops.

Its frustrating as my 7 and Galaxy Nexus are solid as a rock on wifi at work.. both experience the issues at home. I'll try boosting the power output as suggested here tonight and see how it goes

Changing home router to a wrt-based asus rt-n66u and boosting the output power to the maximum US allowed value of 100mW fixed it for me. Other devices were working fine, even lowly archos 28 mini tablets. It seems that jb is misinterpreting signal strength.
I dont want to run a static IP.

Some testing last night, i upped the output power on my ddwrt router - that didnt stop the issue from happening. Then i went with a static IP. This seemed more stable but i still lost connectivety at one point, only for it to return on its own - before i would have had to connect/disconnect from the access point to restore internet. More testing tonight.. its very frustrating! I dont think its a hardware issue as its happening with both the Galaxy Nexus and Nexus 7. Anyone else having simillar issues?

Same here
I Experience the same, happens almost every hour or so.
All my other wi fi devices have no problems, just nexus 7

Hehehe it seems many of us having wifi range issue. I checked my wifi signal strength thru wifi analyzer app and it seems wifi is solid if only I always have more than -40dBm strength. Which means I needed to be always closer to the router, can't make it when I'm already at my room. Quite annoying but I guess I had to send it to service center.

Same problem here....
Weird thing is I have 2 routers connected to each other (dhcp off on second one), having same problem on both routers. I thought it was the internet connection as my HTC Desire does the same thing.
I also tested the nexus 7 wifi with my 3g Desire via hotspot.... and no issues at all for 3 hours+.
So i'm pretty sure its not a nexus issue, unless there are some compatability issues from my nexus to the router.
Ideas anyone?

using static IP at home seems to be stable.. cant understand what different though between work and home that it works fine in the office.. must be a config parameter on my access point at home

Wireless is connected but gray and nothing works! Any solution/permanent fix?

I've seen some chatter about this buried in other threads, but I wasn't able to locate a dedicated thread...so if there is one, sorry about a duplicate post.
So I have a Nexus 7 and a Galaxy Nexus phone and both have this issue. The issue has occurred in multiple environments with multiple routers/networks.
Basically, the wireless on the N7 and both the wireless & cell on the Galaxy Nexus go gray but show as connected with a strong signal. However, there is no IP traffic being routed. The devices have an IP address, and show correct DNS and default route locations and the wireless symbols even show data moving (the little bidirectional arrow deal) but nothing actually happens on the device.
Some have said this means you are not connected to Google's services like Gmail and what-not, but that isn't the case either as you can't ping from the device nor can you go to any websites in the browser, get new mail, get web data for other web enabled apps, or in the case of the phone, get text messages or phone calls.
The only *fix* I've found is to turn off wireless, wait a minute, and turn it back on. This can be really annoying when you have to do it 5-10 times a day on the tablet and it really sucks when you find you miss calls, texts and emails on the phone.
I notice this has never occurred with any of my other Android based devices or iOS devices. This would lead one to believe it has something to do with Jelly Bean and perhaps some background task crashing or something.
Does anyone else experience this? If it were just my phone or just the N7 I would think I had a defective device, but since they both display similar behaviors at different times with different routers on completely different networks, it seems more software related since the only thing in common is that they are both Android 4.1.x devices (it happened on 4.1.1 and now 4.1.2).
I would love to know if there is a real fix for this somewhere!

I fixed mine by getting a new Netgear router...

Again, it happens with multiple routers from the lowly Linksys to Netgear to D-Link to Checkpoint and several more. This is NOT a router issue.

I was having to power off my Linksys router several times a day to allow dropped devices to reconnect again. What happens when you power cycle your router?

What router settings and security method are you using? WEP, WPA? try changing the channels on your router or something

From what I experienced, it is connected to the router but somehow the router has lost net connection. Rebooting DSL modem fixes it for me. I have DSL connection here in Philippines, the telco provided a zyxel dsl modem. From the DSL modem I have Tomato flashed router. Rebooting the DLS modem fixes without rebooting router or the n7. In N7 from gray it turns blue and i can see the up / down arrows, net access is working.

I get the impression that my request/question was too long as it seems people are not really reading. Either that or they are not getting it because they either never experienced the problem, or because they don't take their N7 around like I do so they think it's connected to their home router.
This problem happens at about 8 different sites. Every site has a different router and a different internet connection from DSL to cable to T1.
This problem happens with both my N7 & my Galaxy Nexus and not at the same time at the same site.
I do appreciate people trying to help, but this clearly isn't a router issue but rather it is an Android issue. Focusing on the router really isn't helpful because there is nothing in common. Even the encryption varies from open networks like at a coffee shop, to WEP (yeah...seriously) to WPA to WPA2.

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!

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.

WiFi not connecting

As the title says, when I leave the house and come back it doesn't automatically connect to WiFi, anyone else have this problem?
I've changed the 2.4 and 5ghz to manual with no joy, its back to auto now.
Any other ideas?

Same problem here... :/ Using a Nexus 6p as well, when I get home it never connects, need to turn wifi off, and then back on to be able to connect...

No problem here with my work and home WiFi, both 2.4Ghz and 5Ghz.

I had that problem and fixed it by changing channels and going down from 40mhz to 20mhz. Not sure which made the difference but my 6p connects right away now whilst before I had to toggle the WiFi.

I also have an issue connecting my Nexus 6P to my corporate Wifi network - I am seeking the specific details, but all I know so far is that it's a CISCO Access Point. The Nexus 6 had no problems at all. A colleague did briefly get his 6P connected, but then it appeared to break (he's not sure, but suspects it was after the November security update). It continually tried to connect and then eventually says Authentication problem (despite trying all sensible options for Forgetting, rebooting, changing password, confirming it still works for Nexus 6 w/ new password etc etc)

I am seeing this same issue with all of the 5GHz networks i use. It connects just fine but i need to choose it in the pulldown settings...does not automatically connect anymore.
This is something that started happening out of nowhere. it was fine after the latest update at the beginning of november but now has this issue.
Maybe reflash the system and clear the cache may do the trick but need to try.
Wondering why this is not an issue being spoken about more here. I'm sure its more widespread than it would seem here...

This is happening to my Nexus 6p too. when the phone switches to data network it doesnt connect back to wifi, i have to manually toggle the wifi on phone to connect to my wifi.
I have tried this at my friends home too and it doesnt look like an issue with the router, my nexus 6 connects compeletly fine without any issues.
Also I have noticed wifi disconnect when the screen is closed intermittently?
Is this an hardware issue?

Here is another person having the same problems. I changed my phone but I'm having the same issue on the new phone. It doesn't matter which location my phone is. It happens on every location.

Had the same thing. Connected just fine until something suddenly changed and it wasn't working anymore. It worked on other access points of the same WLAN as well as my home WLAN. Yesterday I changed the DNS Hostname of my Nexus (because "android-[insert random number here]" makes no sense) and suddenly it works again. Could be a coincidence though...

I've seen this issue on 5ghz networks on an HTC one m7, a Samsung galaxy s6 , this device and my Samsung Galaxy tab 4. It would seem to me it's an android issue.

Count me as another one with the automatic connectivity not working. Running stock 6.0.1 on Nexus 6P
