[Q] WiFi connection issue Galaxy S II

I need your help everyone. My brother is using the Galaxy S II running ICS 4.0.1 that was bought along with my S III and it is acting up. GSII is running stock ICS, and still in stock configuration. Phone is not rooted or messed with in any manner. The phone connects and stays connected to the Home Network, but data transfer stops after few seconds. All the other devices at home (laptops, PC, other phones) stay connected and works fine. Home network is through Century link and wireless is through actiontec modem and wifi router - http://www.actiontec.com/products/product.php?pid=264#.UOyOPB3aI7s). He has been using this phone with no problems with the same wireless network for almost 4 months and this issue started almost a month ago. I have no idea why it went wrong all of a sudden and not had any luck in finding a solution from all my research.
Problem: When WiFi is activated, it will connect to the home wireless network and will work for few seconds. As soon as background activity that requires data stops, the WiFi stops working. If I am browsing or a video is playing on Youtube, it will stay connected, but as soon as I exit out of the application that is pulling data, it stops working. I have to turn it off and back on again for it to work, but this issue repeats. From looking at the signal bars for WiFi, its full (I was sitting next the router) upload arrow blinks once in a while but noting on the download. None of the apps are connected to the network. Browser will show loading for a while and then displays no network connection message. I tried google play, youtube, third parts apps etc. to ensure its not just the browser. When I turn off the WiFi, the phone seams to download a bunch of messages and updates that was not being pulled for a while. My GSIII connects fine with the network and it works fine even after being idle for hours. I have no idea what is going on and would really appreciate any help. I am close to calling Samsung and T-mobile, but thought I will try here first as we all know how easy it is to deal with those guys.
Things I have tried so far: I have tried all of the following based on suggestions I read from other forums I found through google search.
1. Factory Reset the system: FAIL. After the reset was complete, I waited for everything to finish loading and then I connected to WiFi by inputting all the necessary details. Same results, will work for few seconds and stops.
2. Restart the Modem and Router: FAIL. I do not think it is modem or router related issue as my S III seams to connect and work fine.
3. Turn off the security for wireless network: FAIL. Same result as above.
4. Try different encryption: FAIL. Same result as above.
5. Forget the Network and redo: FAIL. Same result as above.
6. Change the IP address to Static in advanced settings for the network: Worked for a while and then this stopped too.
7. Change WiFi sleep policy: FAIL. Changed it to " When device sleeps", "Never" and "Always", does not make any difference.
8. Third party apps suggested by everyone: FAIL.
This is where I am at right now. I have tried to include all the information possible. Please ask me if any other information is needed.

Last resort ... try a warranty replacement.
Is the phone experiencing the same issues with other wireless networks (coffee shops, McD's)?

[Fixed]
The issue was not with the phone, but with the router/modem. This was the century link modem with wifi and router from walmart that was bought for $99. Its an actiontech router with built in modem for century link. This does not work and dont bother purchasing it. I ended up buying the NETGEAR DGND3300 RangeMax Dual Band Wireless-N Router with Built-in DSL Modem from Amazon (http://www.amazon.com/gp/product/B001UHMB5O/ref=oh_details_o01_s00_i00) for a 30 dollars more, but it works. Only extra step was that i had to call century link for my username and password that needs to be entered during the setup procedure. The actiontech from walmart did this automatically (mainly because this was a century link branded product).

[Q] Wireless Issues with Note 4

Has anyone experienced issues with Wireless?
I will be connected to a wireless network, can disconnect and reconnect just fine, everything seems to be working, but if I open an app that is trying to load data, it does nothing, as thought I have no connection. I have tried turning it off and on, forgetting the network(s) and reconnecting and the only thing that ever fixes the issue is a restart of the phone. Once I restart it will work just fine until the next "blip" in the radio.
Thanks in advance,
Zach

Yep, I have this issue but only when connected to my WiFi extender. Connecting to the main router works fine.

Just to add info, I connect to a Samsung Verizon Extender every day since owning the Note 4 and have no issues.
I also have never had any issues like the OP mentioned. I would start looking at apps you have installed.
Remove and test and so on. I did a quick search and did not find this to be any known issue.

My issue exist on both me and my wife's note 4. Both exhibited this issue from the initial setup. It's unfortunate and annoying. If it weren't for the camera and s-pen I would've already gone back to my M8.

Problem: Wi-Fi connection
Every time a new smartphone is released there are a lot of reports about problems with connecting to Wi-Fi networks or maintaining good Wi-Fi speeds. Here’s what to try if it happens to you:
Potential solutions:
Try turning your Note 4 and your router off for a couple of minutes. Now turn them on again and retry the connection.
Take a look in Settings > Power saving and make sure that low battery life isn’t restricting your Wi-Fi.
Try forgetting the connection, choose your router in Settings > Wi-Fi and Forget. Enter the details again.
Try the free Wi-Fi Analyzer app and see if the channel you’re using is crowded. Change to another channel if it is.
Take a look at the settings on your router. Make sure that MAC filtering isn’t on, or add your Note 4’s MAC address, which you’ll find in Wi-Fi > Settings > Advanced.
Make sure that your router firmware is fully up to date.

None of these work. Restarting the phone always works.

Thanks. Funny you should post this, I read it right after I posted here and was planning to check out the MAC filtering when I get home. Weird thing is this: My phone connects to the main router fine, with zero issues of any kind. We have a WiFi-extender by NetGear. My phone will connect to it, but will not exchange any data. My computers, HTC One, and my wife's old S5 all connected to the extender fine. Now, neither of our N4's will properly connect to it. It certainly doesn't seem like an issue with the extender, but that's not to say it isn't possible, and I sure hope that it is and not an inherent problem with the phone. Will try some troubleshooting tonight and report back.

I've run into an issue with the wifi since getting my Note 4 last Friday. The problem I am having is it will connect to my wifi network without any issues, but after a while (it could be 2~8 hours) my note4 will lose it's connection to the wifi router and not be able re-connect until I reboot the phone. I have a dual band ASUS router with the latest firmware, when the note4 craps on itself with the wifi, the wirelessG connection will keep asking for the password and come up with "authentication error" and the wirelessN connection will come up with "unable to obtain ip address"
When the note 4 has this issue, my router log shows "Dec 9 16:54:28 kernel: eth1: received packet with own address as source address", checking further into the logs on the router, this didn't start popping up until I got the note 4. I am hoping it is a software issue, Verizon did however confirm that there is an update coming out the the next few days to address a wifi performance issue...
I have other wireless devices that use both wireless G & N and don't have any issues, i've rebooted the router a few times even though that is not the problem. I even hooked up a different router to see if that would help, but the same problem is still there.
After playing around with different settings, I have yet to find a solution to this problem. Verizon support has me running the phone in safe mode to see if it's an app causing the problem.....

Are you by any chance using 5 GHz on your router? I am having issues with 5 GHz connections and no issues with 2.5.

WiFi connected-internet unavailble

I have a peculiar WiFi issue in my office where I can connect to the router, however, I immediately receive a message: "internet unavailable". I am using latest stock T-Mobile ROM. 5.01, Build 20E. Other phones have no problem like my Nexus 5 or other people's iphones. Also, I am running a dualboot partition with a nightly on the same phone and it works fine in Cyagenomod.
I've tried this app: WiFi Doctor, and it finally worked until I went out of the office for a few minutes. When I came back I was at square one and what's worse, WiFi Doctor couldn't cure it any longer.

Anyone? Hello? I'm pretty sure there are a few smart people out there.

T-Mobile G3 stock ROM, Android 4.4.2, build D85110m, encountered the same problem in my office. Likewise, no issue with an old Samsung or iPhones.
From what I've manged to find on the internet, IPv6 or the MTU setting might be a contributing factor.
This isn't a fix per se, but voodoo steps of forgetting the network, switching off wifi, switching on wifi, re-connecting to network (staying on the Wi-Fi screen and waiting to see that it connects) works sometimes. Sometimes it fails and tries to re-obtain an ip address and it works after it re-tries several times. All this while I would be on the Wi-Fi screen watching it.
Occasionally, rebooting the phone helped for a while.
All the boxes under Advanced Wi-Fi are unchecked for me.
My G3 is not rooted, so I've not tested to see if disabling IPv6 or changing MTU fixes it. If you (or anybody else) do test it, I'd appreciate it if you could post your results.

Nexus 5X can't find any wifi network

So I bought a Nexus 5X 2 days ago. When I first started the phone it was running Android 6.0.0 and it didn't have issues. But a update for 6.0.1 showed up and I downloaded it. And then the issues came. It cannot find any wifi network... The problem isn't from my network, because every other device finds my home network and all the neighbors network, but the 5X doesn't find any... I tried factory reset, network reset, cache reset, nothing helped. I even tried Android N beta and for a moment it fixed the issue, but this morning the wifi problem occurred again. I sign out from the N beta and through Mobile network it managed to download the last stable version(that's what google is calling it) - 6.0.1 and the problem was still there.. after some restarts of the phone and some factory resets, i thought the problem was gone, because it managed to find every wifi network in the area, but after i used the phone for 25-30 minutes, the wifi problem occurred again and ever since... So, is this a common issue with the phone, or the android 6.0.1, or is my phone a defected one? Should I go to the store and ask for a replacement? Or will the next phone do the same thing ?

Hi something similar happened to my 5X (6.0.1). It was able to find wifi network but I was not able to use internet even-though internet was working for other devices. I have restarted phone but my phone stuck in to WIFI Obtaining IP address...
I have restarted my router and problem resolved. Happened two times. Might be some bug in software.

I'm currently facing this very same issue, no WIFI networks are showing up. I've already flashed latest N preview with same results, funny thing is that this morning was working just fine. But I had to reboot the phone and now it won't detect any WIFI Network at all.
I'm starting to think I have a failed unit, but since I'm outside the "US" I can't send it back for warranty repair. So I'll just keep it and keep restarting until it's fixed again. This is really frustrating, never happened to me with any device I owned before.

Is it every wifi or just your wifi?
If it is just your wifi, try factory resetting your router after recording the settings, or try removing some entries that my be using NVRAM.
I've seen cases where the router runs out of NVRAM to record the DHCP entries and that causes connection issues. It doesn't show up for other devicdes because their entries are already stored in NVRAM. It is just the incremental new device you add that triggers the problem, so you naturally think the problem is with the new device since all your other devices work with the router.

my solution for wifi not found/working
i´ve upgraded from the nexus 5 to 5x.
i had a really weird issue with my wifi.
only found my wifi when i was not in airplanemode. so i read 1000 of articles about the wifi of the n5x.
just the standard blabla. so i did my own research
while my n5 and my n7 + 2 laptops had never issues my new 5x didnt find my wifi. i really thought it was an hw-issue. but it wasnt.
i am using a fritzbox router. newest update, made a reboot, rebooted phone. nothing happened.
then i checked my wifi channels, set it to manually and instantly found my wifi. i really never expected that the channel got such a big influence. may be the latest update brought a bug for the wifi channels or the hw is just not capable of some channels, dunno. but this is what helped me and it was nowhere mentioned in any forum.
tl;dr
try to change your wifi channel of the router.
edit: btw i found the 5ghz while the 2,4ghz wifi didnt work. but i wanted the 2,4ghz wifi to work because of the short range of my 5ghz wifi.
atm i am on channel 8 and i got no problems with the 2,4ghz wifi network

I don't know about Europe, but usually in the US we only use channels 1,6,11 to prevent overlap.
This is because there is overlap in the channels so you can't really use the in between channels due to too much interference. If you are the only wifi transmission in your area it is fine to use any channel, but if there are others and they are using standard channels for no overlap/interference and you are using in-between channels, your signals are probably going to interfere with each other.
When everyone is using the set channels, then they can negotiate properly and everything works better. With overlapping frequency bands, the negotiation doesn't work well because your signal sometimes looks like noise to the other device.

Hi, thanks for your help but unfortunately it's every wifi... it just hangs on "Searching for Wi-Fi Network..." and stays there...
I already talked with LG and they asked me to send the unit for repair, but I'm no in the US anymore (I was for a short time of period and that's when I bought this phone). So that would not be an option, right now I'm only using 4G and trying to measure it, lol
Just another question, do you guys think I could use a WIFI external dongle through USB OTG? Could that be possible on the Nexus 5X?
Thanks for your help! :good::good:

Hi, thanks for the suggestion but the problem I'm facing it's with every wifi network around, not only mine.
I guess unit is defective, but could a simple reboot trigger this kind of behavior? This is strange, never happened on any device I've owned before. :crying:

Mesh WiFi issues after latest update

My wife has the S8 and I have the S8+. After the latest update (July 9-10'ish) both of our phones are having problems with our Mesh WiFi, but not our non-Mesh WiFi. We don't have issues with the connectivity to the actual WiFi, that always stays connected, but every few minutes, we'll get an exclamation point next to the WiFi signal meter, and our Internet connectivity drops. When I check WiFi connections during this time, it shows "Internet may not be available". Then, after 1-3 minutes or so, it's working fine again. While this is happening, none of our other devices have any problems with Internet connectivity.
T-Mobile had me boot into Safe Mode, and the problem didn't happen at all in safe mode. So, I did a master rest, and with just factory apps installed, it was happening again. T-Mobile asked me to wipe the cache partition. While trying to boot to that menu, my phone went into a boot loop, then after trying several different button combinations, it just turned off and wouldn't power back on again. So, T-Mobile sent me a replacement. Since receiving the replacement, I have not installed the update, and I have not had the problem on my phone at all. But, there's still my wifes phone. T-Mobile tells me I'm the only one having this problem, so they don't know what the solution is.
Our Mesh WiFI system is fairly new, so I kept the old WiFI active as a fall back option. There are no problems when connecting to that SSID, so I'm thinking the update has caused some issues when jumping between access points on the mesh system. I was also thinking maybe it's a double NAT issue, since my modem doesn't have a true bridge mode option. (My modem hands my mesh WiFi router a 192.168.1.xxx IP, but my devices that connect to the mesh WiFi get a 192.168.0.xxx IP) I tried putting the Mesh WiFi in the DMZ and making sure it gets the public IP. That didn't work. The WiFi manufacturer had me open ports 500 & 4500 to the WiFi router. That didn't work.
Does anyone have any other ideas for me? At the point, T-Mobile is telling me that it's my WiFI because it doesn't happen when connected to the non-mesh WiFi. But, it didn't start happening until the last update, and it's not happening on my replacement phone. We rely very heavily on WiFi calling, so this has been problematic. Obviously I can connect my wife's phone to the old system, but we don't get full coverage in our house from it, which is why we went to a mesh system.
I welcome and appreciate all suggestions.
Thank you

I have the same problem with my non-mesh Google Wifi router occasionally. it's annoying.

I'm having the same exact problem with my S8+ and my netgear orbi, all was good until about a month ago, and I've tried pretty much everything, and the exclamation point still comes every few minutes. I can't wait to get rid of this phone honestly. And I've had EVERY Samsung phone to date, and this one has given me the most problems by far. I am on my 5th S8+. HURRY NOTE 8!

Thank you! I just changed that setting. I really hope that works!

Other fix is enabling guest network on your router. It worked for me with Netgear Orbi.

I have an orbi and the above fix didn't quite fix my troubles. After enabling guest mode, then what? Use guest mode? Or does just the act of enabling guest mode change something? Thanks in advance.

Wi-Fi Verbose Logging
Yep! This is a problem the carries and Samsung have chosen to ignore so far. I have the exact same issue with two S8's in my household. Everything, all devices, LG, Apple, HTC, Google, Amazon, PC's, etc., including the S8's worked on our mesh wifi network until the two S8's took on the latest update. After that point neither S8 device would consistently work properly on the mesh network. While all other devices, including a Note 5 and Samsung Smart TV, among a plethora of other devices, continued to work flawlessly. It is definitely tied to the latest update on the S8 devices. I reset the wifi, the phones, etc., including factory resets but that did not solve the problem. Verizon sent 2 replacement phones and we have not allowed the latest update to load on the phones and the replacement phones are working perfectly! The latest software version that screws up mesh wifi connectivity is: NRD90M.G950USQU1AQG4. Beware. So far, neither Verizon or Samsung will acknowledge the issue. Only after hours of trouble shooting and persistence on my part about this issue being a well documented situation in on-line forums did they respond by saying they found one case similar to mine but they did not see this as a wide spread issue. Well, for anyone with a mesh wifi network, this is a big issue and irritating as heck! Come on Samsung! Own up to the issue, support your customers, and fix the problem. The evidence that there is a problem at this point is pretty convincing. All one has to do is go on-line and search the issue and bam, there it is. All somebody at Samsung has to do is take an S8 load the latest update and try it on a mesh wifi network. Really try it that is... It work at first but as soon as the mesh network moves the device to a channel or frequency that is less congested, the device will lose connectivity. Sometimes it is sporadic but eventually it becomes a more persistent problem to the point of uselessness. Either put out a patch or push out the wifi portion prior update for us to revert back to. Don't call us liars and ignore the issue. Hard to achieve customer loyalty and retention with behavior like that. I've already had to muddle through the Note 7 fiasco with the 3 recalls and final discontinuing of the device itself. Samsung, don't leave me hanging again.
UPDATE:
Turning on the Wi-Fi verbose logging did not solve my issue. It seemed to work at first. However, after a few minutes it said it was no longer connected to the web when trying to load some very common url's. However, this time there is no "!" next to the Wi-Fi signal on the S8. It now just stops working. Wish I hadn't let it update on the replacement phone. Again working just fine before the NRD90M.G950USQU1AQG4 update.
Help....anyone!?

After enabling guest-network, forget the main SSID and connect to guest-network. If you "allow guest to see each other..." you will be able to see other devices, like printer, Sonos, Roku, etc.
I tried the fix above and did not work for me either. Going back to login in in guest-network.
