Wifi fails after being disabled - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

I used to think it was my WiFi would fail after enabling the hotspot feature. I now realize it fails simply by turning WiFi on and off. This happens 9 out of 10 times. When I re-enable Wifi, it connects to the SSID, and gets an IP address. It will not pass any traffic. No Internet apps work at all. The only fix I have found is to reboot the phone. I have tried various 'Wifi fix" apps, but nothing helped. They seem to renew the IP and disable/re-enable Wifi. This is a very annoying problem. Anyone else experience it? My phone is rooted running stock ROM with the debloat script that removed a bunch of junk. It has happened through all updates and Android versions as far as I can remember. I'm currently running the latest 5.0 courtesy of muniz_ri (thanks!)

Here is a little more info. It happened tonight. I was able to verify that it was actually online by pinging the S5 IP from my laptop. To make it even more confusing, it has some level of internet connectivity. I went to the Play store on my laptop, and initiated an install for a DNS troubleshooting app. My S5 apparently is able to get the instruction to download it, but it failed to actually download it. I was surprised it was even able to get the instruction.
I tried this app:
https://play.google.com/store/apps/details?id=org.wahtod.wififixer&hl=en
I has verbose logging. It was trying everything you could possibly think of to 'repair' my wifif connection, but it failed as well. Rebooting always fixes it.
Any ideas?

[Q]gmail and market app not working on wifi

Hey guys, I am facing a weird problem after updating an OTA released yesterday by HTC (2.2.1). My gmail app and market app is not working when on wifi. It works perfectly on Mobile data connection though (EDGE). I get a no connection error in gmail and network error in market app.
I have done the following but to no avail.
1. Soft reset and boot into safe mode.
2. Uninstalled task killer app.
3. Deleted all data for these apps and updated the gmail app and setup the account again.
I have not tried the hard reset as yet. Can anyone help me out please? TIA
Thats not good at all. Is your handset branded?
Hey Andy,
Thanks for replying although your reply does make me nervous :s. I am from India and we only get unbranded sets here. So to answer your question it is a unlocked unbranded phone running stock firmware.
By the way after I posted the question I did get these two apps working once for sometime but since then it's the same problem. I am starting to wonder whether it has to do something with the wifi although all the remaining apps are working fine and dandy.
Is the wifi access point owned by you? You could try turning it off and on again, that may help.
Have tried that. It is my home network that I am connecting to using a linksys wireless router.
UPDATE - I connected my phone using internet pass through i.e. sharing the internet through PC via the data cable and I still get the same error which leads me to believe some setting on the router provided by my ISP is causing this. Although what I fail to understand is that it was working fine till yesterday and nothing have been changed in the router setup recently.
Hmm... that's odd. Did your ISP supply your router? My ISP pushed a firmware update to my router about 8 months ago that broke pretty much everything wireless.
Is it just Gmail & Market that don't work over wifi? Does your browser and other apps work?
Yes indeed, my ISP provides a router which is then connected to my wireless router. The strange thing is everything else is pretty much working including gtalk.
If your router supports DMZ and you know how to set it up, you could try putting your DHD's IP into the DMZ to eliminate the possibility of your routers inbuilt firewall blocking Market & GMail.
Maybe a DNS problem? Ensure you have good ones... You can always test Google ones 8.8.8.8 and/or 8.8.4.4
Thanks for showing interest guys. I for some strange reason cannot access my router settings page. I will figure that out but the stranger things are happening with my apps. After a bit of tinkering I have found a behavior which stumps me.
These are the steps I follow:
1. Sign out from gtalk.
2. Go to manage applications and clear cache and data for gmail, market, download manager, Google backup transport, google partner setup and google services framework.
3. Restart phone.
After this my gmail app starts working on wifi but talk does not start anymore and market also throws an error before even accepting the terms. I uncheck and check the background data services and I am back to square one i.e. gmail stops syncing saying no connection, gtalk works as usual and market starts giving connection error (after accepting terms).
I seriously think now there's a serious flaw in the software and not something to do with my router settings.
Sorry for the long post. Thanks for reading.
Simillar problem appeared for me in Locations. I couldn't list country maps for preload on wifi without 3G. After turned on 3G, it listed the maps - turn off - and i could download with wifi.

[Q] Nook Color - Wi-Fi connected but can't add google account or browse web.

I just loaded phiremod 6.3 onto my Nook Color. When I attempt to add my google acount, I get "Can't establish a reliable data connection to the server." When I click on the market app, I get "Could not launch the requested activity." When I open the internet browser, I get "Web page not available."
I have a strong wi-fi signal that my computer, cell phone, and another Nook Color are able to use without problems. The tablet says that I am connected, the signal is strong, and I'm not in airplane mode. I can't seem to find any posts that address the problem of not being able to add a google account AND not being able to browse the web with a solid wi-fi connection.
This is my first post so let me know if I put this in the right category and if I need to add any additional information.
Thanks in advance.
I thought this might be a problem with the newly released phiremod 6.3 because my device was working just fine on 6.2. However, I just flashed back to 6.2 and experienced the same problems. I can't make sense of this especially since the device is successfully connecting to the wi-fi.
Have you verified that if you reboot a PC on the same wireless network it works properly? Could your router have run out of available IP addresses? Possibly not handing out DHCP properly? Maybe your DNS servers you have listed in the Router were down temporarily and your computer was using cached information previously. Several scenarios that could be valid here. I'd like to find out first if a PC on the same wireless, connected wirelessly, is working.
Also do you have MAC address filtering on the network? So you're connecting w/ no issues but not able to surf because it's blocked.
If you go to the admin GUI of the router do you see the NC in the DHCP client table after you are successfully connected to the WiFi network?
Good Luck, I'll try to think of any other things.

Thanks for your reply Deltabear.
I share a wireless connection with my apartment landlord so I don't have access to the actual router. However, I can tell you that his computer is the only other one that uses it, and only for a few hours during the day. I rebooted my pc, and it's having no problems with the wireless connection. I rebooted my other Nook Color, and it too has no problem with the wireless connection.
I just remembered that when I loaded phiremod 6.2 it connected to the wi-fi. Then I experienced a boot loop when I tried to flash 6.3. I still have no idea what went wrong when I flashed 6.3, but everything went downhill from there. I ended up trying to revert back to stock, but instead of a bootloop at "Touch the future of reading" I got stuck in a bootloop at the N. I performed the 8x method and received an OTA update, but remained in the bootloop. At this point I decided to just go back to trying to flash phiremod 6.3, and this time it worked...except for the wacky wi-fi problem.
When you go into settings>Wi-Fi settings Is the router listed with connected underneath it? Or does it keep saying 'connecting'?
If it says connected press the router name and it should bring up a box in the middle of the screen with
Status
Security
Signal Strength
Link speed
IP address
What does it say under each?
Well the problem seems to be resolved but I don't know how or why. I turned the Nook's wi-fi off, and when I turned it back on I was able to add my google account, browse the web, and open the market. I know turned the wi-fi off and on several times yesterday so I am still perplexed as to why it seems to be working now.
To answer your question DreamingWolf, the router always said it was connected. I don't remember what the info was for it when I was having the problem, but I know I looked at it a few times and nothing seemed unusual there...I am however a noob.

[Q] P6810 unable to access any search sites (google.com, bing.com etc)

I have a P6810 I bought from expansys-usa, importing to the USA a device that is not normally sold here. It worked fine for a while, and I very much enjoyed the device.
Then something very strange happened and every time I used the google search bar I got a "Connection to the server timed out" error. Then I tried to go to google.com directly in the browser and I also get the same error message. I tried other search sites bing.com, yahoo.com and each with the same result "Connection to the server timed out"
Other websites (E.g. bbc news), apps including the google play store app (but not play.google.com through the browser), gmail apps etc all work fine, it's just the search sites.
I tried a factory reset and started completely again, the same thing. I rooted and installed a custom rom (Noob 2.1) and the same thing.
I have a galaxy nexus on the same wifi network and that works fine, I have PC (Windows and mac) that also are able to access the search sites, so I dont think it's related to my wireless network.
The only thing I can think of is that there is something related to the fact this is an imported device that means something in the device is stopping the connections, but I cannot for the life of me think of a reason why this does not work. Especially given that it worked fine for the first month I had the device.
Anyone have any ideas?
Have you tried clearing cache and force stopping the built in browser?
Have you tried another browser, such as Opera or Firefox?
If you are rooted, have you tried to fix permissions?
I've also got the P6810 from out of the US, but this has not been an issue for me at all so I don't think it has to do with where the device was intended to be sold.
Hi thanks for the response,
Yes have tried Opera browser with the same results. Not tried firefox though, and I don't see it in the market as an available download.
I hadn't explicitly tried resetting the browser cache but have done numerous factory resets. I have just tried it now though and no difference. Though it also fails to sign into google account at browser startup.
What do you mean by fix permissions?
If you are rooted, then in an app called Rom Manager, there is a menu item to "Fix Permissions" It can sometimes fix some errors.
Another thought, assuming you have Clockworkmod Recovery flashed, then go into Recovery and wipe cache, and wipe Dalvik cache. Other than that, not sure what else you could do.
Sounds more like DNS issues, can you get to any of the search sites via IP Address?
Have you tried another wireless network to see if you can pull them on someone else network?
Try rebooting your router and modem then re-connect and see if that fixes your issues.
I know you dont think its your network, but at least you can clear it just to be sure.
Sorry for the delay in getting back with an update, but my tab went into a boot loop with Noob 2.1 and I have now reverted back to stock, also some not tab related things kept me busy for a couple of days (a new daughter), though that may actually keep me busy for a lot longer
I agree with you, it should be my router I have a Cisco E4200 router, with a Panasonic Cable modem, and roadrunner twc internet, and I have upgraded my firmware to the latest version and checked that there is no custom routing settings (I have never set any, but checked anyway). Seeing as it's more than just a single site that is an error not just google but bing, yahoo also, I don't know where/how that could get set.
When I do reboot of my router it does then work, but only for a short period of time, it's hard to work exactly what that amount of time is, but greater than a couple of hours but less that 24 hours. It is then back to "Connection to the server timed out" errors.
If people have ideas of what to check on the router then I would be interested in hearing that too, but it is just this tablet and nothing else on the network that is having the issue.
I'm stumped. I'm sort of hoping that ICS will come along and magically fix things.

Teamviewer Remote Control Won't Connect on WiFi

Teamviewer was working well on WiFi when I was on Stock Rom. Since I have switched to different Custom Roms, it has not worked on any of them. If I am on Data, I am able to use Teamviewer, but not on WiFi. Error message says "Signed in failed. Please check your internet connection and try again." Has anyone run into this problem and found a solution? Thank for the help in advance.
Fixed:
I finally figured it out after months with this issue. I thought it was the ROM, because it would work sometimes and then it would stop working. Today I found someone who had this same issue and it turned out to be the AT&T Modem. For some reason if IPv6 is Enabled it causes some android apps not to responds or get stuck loading. Why would it affect android apps I don't know, but it does. Maybe someone here can explain why. But if anyone is having this same issue and your modem/router has IPv6 enabled, just disable it.
I tried on a different wifi and it connects. It must some settings on the router.
If you are on Talk talk, they blocked it network-wide the other day
TeamViewer fixed after LineageOS OMS 7.1.1 update. I guess it was a ROM issue. Same update fixed Firefox dark screen.

"Hi, I've had this exact problem for months and I just now discovered out how to fix it. Open your router page in a browser (ex: my AT&T router page is http://192.168.1.254) and in the settings select LAN --> IPv6. Disable IPv6, then save/apply. Turn off wifi on the android, wait a few seconds, turn wifi back on, and voila. "

A5 2015 SM-A500FU WiFi Issues with Speedport W 724V Typ B

Hey guys,
for some week or maybe month, I'm having some kind of issue with my device and the home-wifi-router.
The problem: There are some kinds of webistes that just aren't working in my home wifi. I tried dozens of different browers all with the same result. Some pages that don't work are amazon.de obi.de and kicker.de and twitter.com
Same thing with the Amazon App and Twitter app. They just don't load any content - with mobile data on, it works out.
All of those pages and apps work out with other android devices and also in other peoples WiFi.
I also tried the secure mode, with the same result.
I've heard, that there might be an issue with ipv6, but, unfortunately I can't switch anything on or off in the router settings.
It's gotta be something about the router, but I can't change anything. Maybe there's a way to work around that with some kinde off app or something to turn Ipv6 off, IF that is the problem?
The phone has got stock rom, no root, no nothing. Maybe there is an opportunity with rooting? Warranty is expired, so there's nothing that speaks against rooting, if this might help. But then, I need someone to help me with all that - so far I only rooted an old nexus phone wia root toolkit.
Thanks!

I had exactly the same router. I hated it, my download stream was very slow that I was ready to throw it out of my window. Unfortunately it didn't happend.
Check your routers internet filter settings maybe something blocks your device . Also check your routers wifi settings if necessary turn it off and on again. Reboot your router or in worst case reset it BUT DON'T DO IT IF YOU DON'T HAVE THE ACCESS DATA.
Try to change the wifi settings on your device. Change from DHCP to static and see if it works.
Thanks for your reply.
I checked everything, but there is no filter setting. I restarted wifi and turned of the router several times.
Static IP also seems not to work, the issues remain.

There must be a filter setting. Check the internet tab of your router settings and you should find a filter option.
I looked it up, but there is just the daily reset rule but in the filter tab there is no active rule or something that can be unchecked.
You should ask your internet provider about this situation...
