Angry Wi-Fi issue w Trendnet TEW-652BRP

I have 2 of the same kind of routers, one at work and other at home. One of them doesn't allow the S4 to obtain IP address whereas the other one has no issues. The tricky part is that all the 4 S4(s) have the same issue. I swapped the routers and they still don't work with bad one. I have also contacted Trendnet support and they are trying to show me all kids stuff. I'm software programmer and hardware literate.
The S4(s) work at so many other routers and hotspots without any issues, only this particular router. It's brother works without a glitch.
Any insight would be helpful.

Mad WiFi gets picked up but stops working

My Samsung can pick up my wifi and it'll work for about 2 minutes and then it'll stop downloading data from my wifi until I turn off my Wifi in the settings and turn it back on again. My old iPhone could pick up the Wifi easily but it's only the S4.

I tried resetting the phone and the modem but doesn't seem to work very well. . Anyone got a solution?

No problems at all here using 4 different routers daily and going back and forth between them at times. Didn't fool with any settings on the S4 or routers, it just works.

Welcome to the forums!

I've merged your question in with the thread where others are discussing the issue, maybe info here can help or someone can share their router info.

FWIW, please say what router/modem you have, cheers, thanks!

Just to clarify. My Samsung GS4 works about flawlessly on my home Motorola DOCSIS 3.0 combination cable/router.

My WiFi connection issues occur at multiple facilities where I work. AT&T Tech. Support suggested I set the sleep mode from constant WiFi to never, then toggle back on. Needless to say, it didn't help.

My S4 doesn't play nice with my Technicolor gateway from Xfinity. Have to use slow TKIP security just to get any speed over 4 Mbps down.

I want to use my data but this limbo between being on and not holds me up. Eventually (like after 5+ minutes) I get the sign-in screen. In wanting to use the web sooner I've even tried turning it off and using LTE but it still acts like it's on and attempts to get me on WiFi. Similarly some places have more than one WiFi to sign on to but when trying the preferred one it goes to the other. Then when trying to discard or delete one of them it still tries and will disable the preferred choice. When I try the opposite it does it vice versa.
Problem seems improved after downloading and utilizing the free app., "WiFi Fixer".

My phone, even when sleeping, would keep trying and failing to connect with each mailbox. This problem was solved using the Yahoo Mail App. to handle my Yahoo mailboxes.

Had this problem again today, including my wired internet was down too. My GS4 could see the network, but it had some sort of error and couldn't connect. I would just see saved/secured or somesuch linked to the SSID.

I had to repower the modem and the router and then everything came back normally.

Stray electrons and such.

Unfortunately, as of today, the WiFi problems have continued. I keep getting the WiFi icon that I'm on WiFi, as well as notifications I'm on WiFi when I am NOT. Even if I turn off WiFi and rely on 4G, WiFi comes on itself like it's some sort of a zombie with a mind of its own. It keeps unsuccessfully but SLOWLY trying to get on WiFi.

This phone and/or the provider (AT&T) have some real problems with WiFi. Local Verizon dealer told me it has addressed these WiFi issues, a reason for its delayed launch, but this is NOT SO.

The issue I have when I am connected to wifi is it shows 4g in the upper screen also, to me it seems like both 4g and wifi are connected, can others let me know if you see both wifi and 4g on when you are connected to wifi?

When you are truly connected to WiFi, the 4G icon is replaced by the WiFi icon with 2 small blinking arrows beneath it. With what I call "false WiFi", I've had the icon with non-blinking arrows, then minutes later after getting "connected" notifications, I'll get the WiFi sign-in screen or notification. This is absolutely maddening and dysfunctional. If I didn't have the unlimited data plan, I would be worried about my data usage.

Notsure Anyone Else having WIFI Troubles?

I have a Galaxy Note 2 and our home network WIFI works perfect. I leave 4G and WIFI on all the time and it switched automatically with no problems and stays connected to WIFI.

My wife's S4 just wont stay connected to WIFI. I can get to connect but it is very intermittent and unreliable. It just randomly disconnects when it wants.

Anyone else having WIFI connectivity issues? Is there a setting I dont know of?

FYI - Both are Verizon phones

I'm having an issue with wifi as well. I tether my gs4 to my verizon unlimited hotspot for use at home and the data terribly slow. Subpar 3G speeds when I download apps from the App Store. I've seen something about going into the wifi menu with *#0011# but that does nothing on my verizon gs4. Any help from fellow verizon users?

To answer you, Samsung has acknowledged wifi issues with D-Link routers and their firmware.

I am using an Apple Airport Extreme router with a Net Gear Extender and Apple Repeater.

What is weird is the the Note 2 works perfectly fine...the phones seems so similar.

I have a verizon s4 and when I enter these numbers in the dialer nothing happens. IT is a stock s4. why?

Again.....I have no issues at all with my S4 functioning on WiFi with my home router.

Unfortunately, to me the main issue with this phone's WiFi is connecting when away from home where I use 95%+ of my phone's data. It then fails miserably to work effectively with WiFi.

I have been told that this issue is with many models of d-link and a few other brand routers.. to date the only work around is turning Wi-Fi off with these routers or purchasing a new one. I am told both D-link and Samsung are aware of the issue.

I have a Verizon GS4 and a Netgear R6300 router. I was having one of the problem mentioned here where it shows it was connected via WIFI with a strong signal, but download speeds were very slow (like dialup speeds). My router in dual-band and I was connecting at 5G frequency. When I connected to the other band, it has worked perfectly fine ever since. I tried other channels and such, but nothing else seemed to help.

Do you notice any difference in your voice or signal quality between the note 2 and the s4?

Speaking for myself, while I had the GN2 for less than 10 days, I haven't noticed any difference between the GN2 and the GS4 on those issues. If they exist, they are too subtle for me to pick up. But I've been in the GS4 for several weeks now, so those differences, if there were any, could well be masked at this point.

Wifi not working on Belkin router either. Anybody else having problems with the Belkin brand? I've checked for firmware upgrades and it's on the latest firmware. I've got my ssid setup as wpa and it fails on obtaining ip address over and over again. If i remove the security it connects just fine. when i set it up as wep...same thing happened....failed to obtain ip address. Is samsung ever going to address/fix the wifi issues it has with the s4? Also....I can connect to other wireless networks that are non belkin or d-link branded just fine.

Default It's Android - not the phone!

Fellow S4 wifi sufferers - I have done a lot of searching on this and found it is not just a Galaxy or Samsung problem (a lot of angry Droid and HTC users out there with this prob also) It sems to have cropped up when Jellybean was updated (I believe it was 4.1.2? Would have to go read the posts again) and it seems to be related to the AGE of your router. I had a DLink 635 from 2006 - they stopped supporting it in 2010. Everything works BUT my S4 and I work from home, so I need it to work here. After researching it (Google Jellybean wifi issues to see for yourself) I decided to go out an buy a new router - found a list of SUPPORTED ROUTERS (below) and got a NetGear N600 and now have fantastic connection to wifi. Still run into the problem at the occasional restaurant or coffeshop. If your router is more than 5 yrs old, first update the firmware. If that doesn't do it, then look at the list below and start shopping around. Or wait for Google to fix it (I might not live that long) Note on the list - the "unsupported routers" appear to be the tpye that a service provider would install in your home and the "supported" ones are mostly ones you or I would buy.

Hope this helps (Hmmm -now if everyone in public places would just upgrade their routers...)

Here is a list but not limited to the unsupported routers that will not work with the Jelly Bean update

Default More on It's Android - not the phone!

I also ran across this link on Google's Android handset forum - it is just one of many, but Google is aware of this and has been for awhile, just doesn't seem to be able to get out a fix for it... (supposedly it was in 4.1.2 - results indicate otherwise)

Issue 36638 - android - Android 4.1.x Jelly Bean does NOT connect to 802.1x/PEAP WiFi networks - Android - An Open Handset Alliance Project - Google Project Hosting

If you had a previous "android / google" device, I think all that information is kept at google.

I use a Droid Bionic and then bought a Nexus tablet. When I set it up at work I didnt give it much thought, connected it to the network (during setup). But when I got home, it already knew my router and password. HOW CONVIENENT... until I realized that it had ALL of my wifi connections listed.. NOW ITS SCARY!..

At home I have a Linksys EA4500 (don't quote me on that) and at work we have a Cisco Wireless system all over the building. I got my S4 about two weeks ago on Verizon's roll-out day. I had problems connecting to the WiFi at work and at home. It would connect, disconnect, connect, disconnect... for several minutes before finally connecting (or not.) I was ready to return it and get another unit, but decided to do a factory reset (from the recovery menu) because I knew they would try that at the store. After rebooting and getting everything set up, I have had zero issues connecting to WiFi. It jumps right on both systems immediately and stays there. The WiFi at home is lightening fast and the one at work is as fast as that system ever is. Maybe we should stop referring to a Factory Reset as "like right out of the box" because right out the box for me wasn't good. I hope this helps someone.

Default Public Service Anouncement. Comcast Gateway WiFi Issue.

After a thorough investigation I found that Comcast customers with a gateway (Modem, Phone, router and wireless all in one) model TG862G for sure (other models may be involved). This gateway has issues with several wireless cards. Initially it was thought that issues were only with Ralink WiFi cards however problems have come up with Mac Book Pro and Samsung Galaxy S4 among others. The issue didn't exist initially but after an automated firmware "upgrade" from Comcast the problems appeared. The two solution Comcast has is to replace you Gateway for another gateway (DO NOT TAKE THIS ONE, same problem will come back); the second is to replace the gateway for a plain modem or EMTA ( modem with telephone service). Since Comcast doesn't offer wireless routers anymore any way you have to buy your own (I recommend this route since you control the type of router you will use). Love it of Hate it this is the reality. Good luck guys!

I've had a similar issue as mentioned earlier in which the Wifi runs slower on the phone than the network. Normally I would just turn off Wifi, but a new problem arose within the past couple of hours in which Wifi won't turn itself off. After a minute or so, it will automatically reconnect with my Wifi even after turning off. I tried restarting, powering down and powering off, and even forgetting my Wifi connection. It still did the same thing, but would just ask for the prompt for my Wifi password. Anyone ever hear of this issue before?

Aha...I described this very issue in my prior posts. The phone's WiFi has a mind of it's own. This continues to be a very big problem for this phone and for Samsung....therefore, a problem for the owner.

Have you guys done anything to your phones at all? Bone stock all around?

The only change I've made is to run Nova Prime and disabled a bunch of stock bloatware. My wifi is controlled by command. It has no mind of its own at all. I toggle it on or off as desired (I generally leave it on all the time), I just tested it and it operated as expected... off on command... then back on and connected on command.

Just spoke to Samsung support about my 6 wk. old G4 with continued WiFi problems.

After jumping thu the hoops of waiting on "hold", then popping the battery and giving them the appropriate serial numbers, I talked to a rep. who talked me thru various things that I already tried, then transfered me to level II support to someone I spoke to for 15-20' and re-described the problems I've been having with WiFi (which have worsened lately). Essentially, he couldn't do anything for me and told me it was up to ATT to replace the device.

CONCLUSIONS: Samsung has a real (software or other) problem with this phone, Samsung's customer service leaves much to be desired, and I want my iPhone back!

Are there any settings in your routers for IPv6? If there is, go to those settings and disable IPv6 in your routers.

I had the same issue on my Linksys e3200 where it would connect but I wouldn't be able to download anything. I disabled IPv6 and it fixed it.

Default a knowledge Verizon Sr. Support Tech

Had a great experience with a VZ tech support last night. She offerred a work around for this wi-fi issue until Samsung updates....... it worked for me so I wanted to share. Caller ID, if removed completely, will eliminate the problem for many. To accomplish this....settings > More > Application Manager>All (on the horizontal bar to the far right at the top)>Caller ID>Force Stop>Uninstall and reboot the phone. Hope this works for others!!!

I have AT&T, but what specifically with the WiFi issue has this remedy helped you with?

Canesfan: This fix corrected the wi-fi issue with my d-link router being dropped after the s4 connects at home and then the s4 continally searches for a wi-fi connection. Now I have a true wi-fi connection at home (and the 4g icon is gone from the screen). So for me this is a great work around for the problems identified in this thread.

P.P. thanks. My problem is one of not being able to connect and/or hold a WiFi connection in the larger more industrial venue rather than at home where I have no problem. 99% of my WiFi usage is not at home where I have my iPad or desk top computer for internet or other data use.

Your described fix still might be worth a try although I'd hate to trade off my caller i.d.

DLink users:
I have found, sadly, that taking off mixed mode with 802.11n seems to work. This was on a Dlink DGL4500.

I had already updated to the latest firmware, rebooted both phone and router, and tried switching to just 5Ghz band, but problems continued.

Thumbs down Contacting Samsung regarding WiFi problems.

Samsung customer assistance is one of the most lame in the business. Not only did they try to double-talk what I was trying to tell them about my WiFi problems with this phone but they are in complete denial of a problem. Furthermore, they offered absolutely NO solutions. They absolutely suck.

Next time around I'm definitely going back to an iPhone. Oh, and Apple's customer service, in contrast, is excellent.

Default TKIP over AES...for now

Check that your wifi router is running the most recent firmware, and also that it's using AES rather than TKIP encryption as I've had problems with several different Android devices connecting to APs using the latter.
The issue is well documented and not just fixated on D-Link brand devices. I spoke with Samsung guys this week and they all agree that until a patch can be issued, users with the Wi-Fi connectivity problems should switch their AP to use TKIP instead of AES.

There are also issues using LEAP or PEAP authentication, which has no current workaround.

Samsung is working on it and will issue an MR ASAP.

That caller ID feature I thought was a free trial and is pay for service after that.

Is Samsung aware of the WiFi issue? Seems from some posts here, people reach level II support and then are told to replace the phone, if that is the case Samsung is not acknowledging any issues?

With Samsung level II support telling me to contact AT&T to have them replace the phone, what do you think?

Dealing with them is a cluster frick.

Similar issue here. Stays connected at home (Virgin Media superhub), and elsewhere, but at my gf's apartment it keeps dropping and reconnecting to her Sky hub. This happens every couple of minutes for a while, then is fine for a random period, then starts again. Her devices do not have this issue (iPhone, iPad, Windows 7 laptop)
