[Q] Wifi slows astronomically when my S6 connects to it - Verizon Samsung Galaxy S6

I have DSL 6mbps connected to a Linksys E2500 router, very good connectivity, and my PC is hardwired to it. I can play 720p videos on 3-4 devices with no buffering. I just got a brand new S6, set it up, synced, and once I connect it to wifi, it slows down astronomically. I can barely load one 144p video, the phone itself can barely load anything. I turned off auto backup, smart switch wifi, and nothing helps. I can't find anyone with this problem.
I turned off everything except my PC and the S6, load a game, get 60ms ping, turn on wifi on the phone, and I get over 999ms of ping. What is the problem? I have tried restarting router, phone, resetting network configs on phone, etc. Nothing helps.
Any ideas?

Try a router firmware upgrade.

Why would I need to upgrade a brand new router with updated drivers that works flawlessly with every other device except this one? It is updated.

You should always run the latest firmware on your router, it usually fixes security and compatibility issues - it might not fix your problem but it's a good place to start.
P.S. You don't need to post the same question twice: http://forum.xda-developers.com/verizon-galaxy-s6/help/wifi-slows-to-crawl-s6-connects-t3121991

[Q] Wifi signal high but no internet connection (Samsung Galaxy i5500)

I just upgraded my router to a wireless one. Firstly, it's connected via ethernet to a PC and it is happily getting internet access.
On my i5500 I get a strong wifi signal. Wifi Analyser shows the signal at max constantly. I can also connect with Gmote and it works just fine.
The problem is that I can't actually access the net at all from the phone.
So basically I know that my phone is talking to the router with no problem. It's just getting out onto the internet.
Does anyone know of a solution?
try logging into your router and change the broadcast channel to something else and test it again. it should be something like a/b/g mode... define a single channel and see if it works.
I had originally thought that was working. It did for the first few minute where I had connection but then it just dropped.
I have noticed that I have some very small bursts where I can connect.
Do you think that trying the different channels may be the solution?
I have the same problem. Have you found a solution?
Still no solution. I went through every channel and every encryption method.
So far I've found that having the channel set on 'Auto' and then disabling encryption seems to give me internet connection through WIFI for at least the initial period but it eventually drops. But that's also not always.
I've also Googled it to death and found nothing. If you do find the solution please post it here and I'll do the same.
Maybe we can help each other.
make sure you entered the right password of wlan.
use a pc to connect the router and in the wlan you'll find the password.
Ok, just to clarify. My phone connects to the Router via WLAN. In fact I can use Gmote to control my PC. So the WLAN connection is great.
The problem is accessing the internet when using that connection.
I had similar problems with a router last year. I resolved the issues by flashing DD-WRT firmware. The manufacturer's firmware was junk.
Sent from my ADR6300 using XDA App
I had that idea but they don't have firmware for my router yet. I have asked them if they intend to make one.
Any chance the firewall on your phone is blocking your browser from using the Wifi?
Sent from my DInc via XDA App
I have no firewall on my phone.
Ok I've tried some new stuff and they I've had the longest connectivity so far (which is about half an hour).
First I made sure my Wifi wasn't set to turn off when the screen goes to sleep. Second, according to a forum I read, Netgear recommends channel 7. If that channels doesn't work try 1,3,6,9,11,13.
I then disabled encryption.
Fortunately no one near me uses Wifi at all and I've got the kind of walls that stop the signal from getting outside.
Anyway. It's working so far but I'll monitor and report.
[edit] And I forgot. The router was checking for firmware but it wasn't actually finding so I downloaded it myself. Seems that also made a difference.
Ok. I can confirm after 2 and a half hours my internet connection is stable. I even left half way through and when I came back it connected perfectly.
So as a summary here's what I did:
1) Get latest firmware
2) Change channel to 7
3) Disable encryption
I will change encryption and see if it still works

[Q] WIFI Connection Issue Asus Transformer

Hey,
Was wondering if anyone had any solutions to this issue.
I can connect to my router with the asus transformer, successfully get an IP, but can not connect to the external web. I can make internal connections, but again, nothing external. I have no problem with my samsung sgs i9000m, various laptops, ipod touch, etc etc..
The router in question is a speedtouch 780 (dsl modem, voip, and router in one). Ive tried various encryption schemes, and even tried to leave it open but to no avail.
I can create a wifi network with both my imac, and with my samsung sgs and the transformer can connect, and also move internet data!
Very weird, I dont even know where to start trouble shooting, can anyone help?

Sounds daft but i assume to have tried rebooting the router .... my router occasionally gets confused based on the sheer number of wifi hardware we have in the house .... otherwise have you tried changing the wifi channel ? read somewhere else that people were having problems with channel 13 ???
hey thanks for the reply.
Yes probably rebooted the router a half dozen times, restored firmware, no go.
Ive bounced around a few channels, doesnt seem to have any effect.
Im really stumped!

no not via the router, the little wifi icon at the bottomcorner stays gray (means connected, but not to the google servers, it goes blue when it does connect to the google servers.)
It does connect and go blue when i create a wifi network from my cell phoneusing my cell data connection

well on the plus side that implies its not a TF hardware or setting issue
not sure I can help on the router front as im no expert have you checked what IP address its allocated ? are you able to see the TF from the router info page ?

yeah im thinking its a router issue.
i can see the transformer, it appears to look exactly the same as all other wifi devices that connect to the router...
stumped =/
Under your wifi settings long press your wireless network under the list of networks available, you should get a "modify network " link pop up, change the setting from DHCP to Static and enter your settings manually. Had a similar issue with an iPod touch once, wouldn't go on the internet unless it had a static address even though all settings were identical to what it pulled from the router using DHCP.
Update Transformer firmware? Leaked official 3.1 is out has updated wifi drivers too.
If no go after that, factory reset the Transformer.

I have the same problem with my TF101, I did all of the above, but the WIFI indicator stays grey. I have a good connection with my router.
When I connect with the router at my work, I have the same. So, the problem is TF101 related. When I bought it two weeks ago, it worked. Two days ago I flashed Prime 1.4, and that worked too. Since yesterday I have this problem, and I tried all to solve it. Other firmware, factory reset....everything. Can somebody please help me with this?
Not sure what this issue is, I never had it with the previous WiFi build, only after the 3.1 changes. I have had several occasions where sitting within 5 ft of router, it would not connect. reboot solved it each time, but I have noticed that it appears dependent on when you unlock during the boot sequence. If you let the boot sequence complete before unlocking, it never happens. If you unlock during the boot sequence, it might.
ASUS Tech Support please note.
@rumbleweed : thanks for the response!
Update : I pushed the original 3.0.1 WW blob to /data/local/ with ADB to unroot my TF101. After that the WiFi icon stayed gray, but I had a working internet connection. Later I updated it to WW 3.1. To be sure I did a factory reset, and now it is working again. First the WiFi notification icon stays gray for a few minutes, but after that it went to blue. I have a unrooted 3.1 WW TF101 now, but I'm happy!

Hi i had this same problem when i first unboxed my Asus TF, Wifi said i was connected to my Linksys router, and i even had an IP address but no internet.
In my frustration y plugged it to my PC which is connected with an ethernet cable to the router and voila, internet icon changed from grey to blue and 2 small arrows started to appear. The internet was now working and i updated the thing from 3.0 to 3.2.
Not sure why this happened but ever since that time i have no problems connecting even on different routers and modems.
Hope this helps.
Had this problem myself from unboxing, tried everything suggested and still no joy.
went and got a linksys router to replace my dlink, everything working fine. tried it with a few networks now and seems to be a problem with dlink routers.
I have this same issue at my school. Up until 3 weeks ago it would always give me blue, then randomly it started staying on white. I can use the net, just not connect to the Google servers.
It works fine everywhere else.
Strange.
Try playing with the wifi disconnect policy?
having a different problem here. been using my home internet since unboxing. all was fine. then one day the connection was grayed. tried rebooting and everything didnt work. i went to setting, clicked forget network. then it never appeared again.
and yeah, its a dlink router. any help ?
Problem: fixed!
I had a solid wifi connection most of the time, complete with a solid blue wifi icon. But my wifi was EXTREMELY slow and intermittent. After a great deal of forum searching and trying every possible suggestion, the solution that finally worked for me was to change the channel on my router from 'Auto' to 6. Flawless connection now, and no more dropped signal.
Hi there,
I tried one thing - took off the lock feature from my transformer and now it's back to normal.
If I turn it back on I am back to square one.
Can anyone figure out how the lock feature affects the WIFI connection ? Is there a bug and is there a fix ?

Jumping in a bit late, but am having similar issues. Just got my TF but have not been able to connect to my dlink router (dir-655 - onlyl couple months old). The router works fine for everything in the house. I know the settings well and have tried many things (went through all channels one by one, messed with different WPA security options, even removed security, etc). Nothing allows me to even connect to the router/network.
In the Wifi settings is jut keeps saying 'connecting...' and 'scanning...' over and over. I am about to take this thing back as I really can't buy a new router at this point (no new firmware for router is available by the way, I checked).
Has anyone confirmed that dlink routers can work with the TF and if so, what are the settings you are using (channel, WPA security settings, dhcp or static, etc)?? This driving me nuts. I want to keep this TF but won't if I can't get it to work at home.
Oh and by the way, when I use my Droid Inc 2 as a hotspot with WPA security, the TF connects without issue. So the TF appears to be fine, it is definitely related to the dlink router.
Thanks!

[Q] Wifi Issues

Hello everyone. I have been having a wifi issue lately and I'm hoping someone here can help me out. I can connect to my home wifi and surf the internet, use Facebook and watch Youtube and use some other apps. Lately however, I am not able to use apps like Pandora, Slacker, 93.9 The Beat, POF, OkCupid and MeetMe. I'm sure there are others as well that I haven't tried yet since this issue has started. I can also connect to xfinity wifi (I'm not sure who's that is) and all of the apps work fine. I am on the stock ROM, S-Off and unlocked running Android 5.0.1 If any one could help, it would be appreciated. Thank you in advance.

Do you use a proxy at home? I know some apps don't work well with proxys...
Change anything recently on your home router?
Did you say everything works FINE on xfiniti wifi?
Xfiniti Wifi is a major cable operators wifi. You'd need to have access to their services to use their wifi.

Hello bigblueshock. I have not made any changes to my phone/router/modem. I have shut them all completely down and restarted them and that did not help. And all of the devices are up to date. Yes everything works fine when I connect to Xfinity wifi. I have ComCast/Xfinity cable and internet. I'm not sure if it's my Xfinity wifi I'm connecting to though. I have signed in on a prior occasion and I was connected, so maybe. But when I try to connect to my wifi (the one that I know is mine) that is when I have my issues. It was working fine up until recently. I am not using any proxy.

If you're connecting to a different WiFi (such as XFINITI) with no problem. I'd say there's a high chance somethings going on your end... whether it be router/modem related.
One way to test is to connect another android device to YOUR network, and see what happens... Possibly even an Apple device. Any friends or family have android devices?
If the router is one comcast provided.. maybe they pushed an update to it which messed up something.

I have an old Samsung Omnia II that is running on Windows 6.5. When I connect to my home wifi, Slacker Radio works fine and so does everything else on the phone. It connects directly to my Netgear wifi it does also show xfinity wifi as available as well. But it doesn't have the app like my much newer HTC One M8 has. My M8 does show my Netgear home wifi and that is the one I'm having issues with. It seems like it's my M8 that is having the troubles.

If you are at your own home you shouldn't be on the xfinity Wi-Fi side. You should be on your private network.

Question Wi-Fi and Bluetooth issue on M12

Whenever I use bluetooth ear buds with my Samsung M12, while I am accessing internet through Wifi
(30mbps connection), my internet speed goes down drastically to a point, I cannot even watch YouTube video(360p) without buffering. (Update) Situation have become worse now, can't even open any web page, nothing works when I am using Internet through WiFi and connected to my buds via bluetooth (have tried different buds, headphones, neckband etc).
It happens only when I am connected to buds/headphones etc....otherwise there is no such issue while using bluetooth speakers, or transferring files through bluetooth or simply if bluetooth is turned on. DON'T HAVE ANY IDEA WHAT THE PROBLEM IS, HAVE TRIED RESETING MY PHONE,BLUETOOTH SETTINGS EVERYTHING.
(tried samsung service center also as phone is under warranty, they kept my phone for a week and did nothing)
Nothing works.
I am forced to use wired earphones and headphones while using WiFi.
(HAVE ATTACHED TWO VIDEOS EXPLAINING THE WHOLE SITUATION)
PLEASE CAN ANYBODY HELP ME.

It is because you are using another phone as a hotspot, this setup is slow. It requires more data when using hotspot. For each bit of data that the device you are viewing uses, the device providing the hotspot is consuming several more bits of data, a very inefficient setup. Using Bluetooth at the same time also slows things down because the radio is having to do extra work.

I understand that it is not very efficient setup, I did it in emergency situation. But the problem occurs on Samsung device specifically, i have F41 and oneplus 3T both works perfectly on this same setup while their individual Bluetooth is turned on, only M12 seems to not work

Does this persists on other devices too ?
And does it happen in chrome only or around the whole ui
Try system update
It happens because BT and WiFi shares the band the wireless connection. Either setup your wifi to use 5Ghz or change the channel of the router to something optimal, where other devices (microwave etc.) doesnt ruin your signal.
