At the doctor's office yesterday. I easily and quickly connected to his open guest WiFi. My wife's identical S4 kept trying but never connected. I restarted her phone several times with no result.

Don't know if it's my imagination (or wishful thinking) or an anomaly but since my 4.3 update, the WiFi seems less schizophrenic. It seems to obtain and hold WiFi more efficiently. Stay tuned...

WiFi still seems improved now at an additional 2-3 facilities, and counting. (Note: this also happened after the last update, but proved temporary for some reason )

I did not see his reply as an insult. He merely pointed out that many of us paid out alot of hard earned money for these devices. We just simply want them to work as advertised. We never envisioned we would need to be engineers just to get WiFi to work. We did not buy into a beta testing program l, we, thought that the manufacturer would have taken care of that prior to releasing products to the consumer.

And calling people who don't have the problem a shill by saying that they should work for Samsung, if they don't already?

That's what it keyed on, it's been addressed.

That subject is closed.

Being screwed by not having the issue addressed, very much open ok.

I had the same problem with a new router (ASUS N66U, and I bought this to replace Dlink router to resolve other issues the phone had), and another person had posted about using TKIP encryption type, so I setup a guest network on my router with authentication method as WPA-Personal and WPA encryption method as TKIP, and this problem has gone away. This problem however exists in places where I have no control of the router.

Hope this helps.

Angry Wifi help!!!

I have a droid razr and when I go into settings to turn on my wifi, after five seconds, it toggles back to off. I rebooted the phone, deleted all downloaded apps, and then finally I did a factory reset. Nothing is working. Is there anything else I should try???

I've been having problems with the wi-fi since upgrading to 4.3 It connects, but sometimes says it got dropped due to the internet quality not being good enough (which is a load of crap, as I never had probs with 4.2, and the router is in my office/bedroom. It also seems to just drop off without asking me (maybe a new powersave feature?)... which is REALLY annoying, as I get up in the morning and have to manually connect it to see my email/FB notifications

Has anyone else found a solution?

Thanks!

My Galaxy S4 (my second one, as this is a replacement) is a MESS as far as WiFi. I am still waiting for the folks at Samsung to acknowledge that some with this phone have a problem, stop being in denial and to come up with a solution.

does anyone have issues trying to send a picture over the stock messaging program on the s4? If I am on wifi at home and try to send a pic it NEVER ever sends. Says my internet connection is unstable. If I turn wifi off then it sends. I have 4.3 but ever since I got the phone back in July I have had wifi issues starting two weeks after I got this phone. I had a linksys router before and bought the new asus router and still no difference. Made sure that wpa2 was being used then tried wpa and still no difference.

Starting to piss me off with all of the updates to my apps and just received a message today that I am approaching my data limit because I leave wifi off because of the issues with it.

I have issues every where I go. For some reason it will not send a picture through mms if I have wireless enabled. It does try to send over 4G as it looks like 4G and my wireless are fighting each other. I really do not want to do it but I might start with a factory reset. Just irritating that the money I spent on this phone and the wifi only worked the first two weeks I had the phone.

Since the 4.3 update my phone has been switching back and forth between mobile data and Wi-Fi without me doing it. When it does switch it tells me that the network connection is too slow. I got in touch with my Internet provider and they say that nothing is wrong here. This is when I am about 10 - 15 feet from the router. Any help would be appreciated.
I also have problems other places but I am home with my kids the most so that's where I notice it

Howdy Folks,
Ever since 4.3 was installed on my phone I can not make or receive phone calls using wifi calling I either connect and they can not hear me or vise versa and they say all they heard was beeping. If I turn wifi off once call is connected it locks my phone and I have to restart it. Any one know of a fix? Or should I just leave wifi calling off?
Thanks in advance,
Merry Christmas,

Thought I would post this here seeing as i'm having issue with my WIFI on my S4. So I loaded CATACLYSM 11.0 Full, after deleting my stock ROM. Everything with the CATACLYSM is working perfect except for my Bluetooth/WIFI. I am unable to enable it. I move the slider over to turn it on and it turns right back off with an error (Unfortunately, System UI has stopped)

Any thought or ideas as to fixing it would be helpful, and sorry if this is in the wrong forum section..

With more than the usual problems with WiFi I've been having since the 4.3 update, I called AT&T. I was advised to do a factory reset.......surprise, surprise. Helpful, huh?

Factory reset does NOT solve the problem. I've done this countless times.

You know it and I know it, but they won't consider doing anything about it until a factory reset is tried.

I'm seriously considering ditching the phone. Shame on Samsung. I can't see myself buying this brand again.

Hi folks, I believe I found the solution to this particular problem.

Under WiFi settings, press the Menu key and go to Advanced. Then, disable "Auto network switch."

I was having the EXACT same problem as above, and had tried many things short of a factory reset, until I came upon this setting. After disabling that, my WiFi has been solid for about a week now.

Basically I think what is happening is Android is disabling WiFi when it thinks it can get better speeds via mobile/cellular data. This makes a certain amount of sense if you think about it, but, it may not be what many of us want.

(Btw, after changing this myself and seeing the results, I did some more specific searches online and did find some others had done this as well, and also disabled "Always allow scanning." I had disabled mine prior to figuring out this issue so I don't know what would happen if you had that setting still on, but Auto Network Switch disabled. So it's possible you have to disable both.)

One caveat: the phone now annoyingly prompts me for whether or not I want to join another WiFi network once I go beyond the range of my own router. I haven't found a way to stop this yet, but, this situation is still far preferable to the constant on/off problem, so I can live with it if there's no way to stop it.

Thanks for that! I had an issue where my wifi kept turning off and this fixed it AND kept my logins saved. Do you know how annoying it is to have to enter your wifi password multiple times a day?

I had wifi issues. The phone constantly notified that my connection was weak (not) and then would drop the wifi only to re-connect and notify, drop, re-connect...
I had done all the phone settings others suggested. Did not work. So my router seemed like the next logical step.
1) Went to my router settings
2) Clicked on the WIRELESS settings
3) Found the Security Options: WPA2-PSK [AES] was checked
4) Checked WPA-PSK [TKIP] instead
Restarted the wifi on my phone and have not had one notification or dropped wifi since.
I have a NETGEAR R6300 router.
Hope this helps.

Only thing that worked for me was a factory reset. It wouldn't even hold a connection to an unencrypted 2.4 GHz network.

My problem is getting WiFi to function at the multiple facilities (about 18) that I work out of. As I've pointed out, my home router is not the problem. I wish Samsung or one of us were able to solve my WiFi dysfunction which renders it useless.

The failure appears to be in Samsung's software, maybe it's not interfacing with the Qualcomm chipset properly because it was originally written for Exynos, something like that. AT&T originally pulled the 4.3 update, ostensibly due to WiFi issues (I don't think they ever admitted to that though). When the update finally arrived...it still caused WiFi issues. Given that AT&T makes money if your WiFI is broken and your phone moves you to network data and you go over...lately I haven't felt AT&T was trustworthy.

I think that's a stretch. No doubt, AT&T makes money when you buy another tier of data, but I have to wonder how many people really go over their limits. Is it that often and that many?

I was never pleased with the Bluetooth connection on my S4 (my S3 was much better), so installed 4.3. The Bluetooth connection is better, but suddenly the S4 no longer makes a secure connection to our 2.4 wi-fi. It recognizes the difference between a correct password and an incorrect one. It just won't connect in secure mode.

AT&T customer service said they're aware of the problem. Sent me a replacement phone which had the latest updates on it. Same symptoms, so I'm sending the replacement back.

I wonder if the update is merely faulty or if it expects some newer protocol or handshaking? Even if it did, you'd think it would be backwardly compatible.

And I understand why you think so. Thus far, no one can explain why your experience (and a few others) is so radically different from the majority with no issues.

Not to take away from your issue. But if it is a Samsung issue, I would think the issue would be 100%.

New info.

Per my post above, after the software update to my S4, it wouldn't make a secure connection to our home Wi-Fi.

I just downloaded an update to my Netgear wireless router -- and the S4 made its first secure connection.

So, my best guess is that the update to the phone is assumes some update to the handshaking/connection sequence and isn't as backwardly compatible as it should be.

If you're having problems connecting after a software update to the phone, see if there's an update for your router.

Best of luck.

Not necessarily. Someone who never uses WiFi would never have issues. Others might be using some type of AP that isn't actually having a problem, there may be some.

Regardless, this problem is very widespread, there's a lot of people having WiFi issues with the GS4, it's definitely more than "a few." If you're not having issues, congratulations. But in my professional opinion, after collecting information and doing testing, this is an issue with Samsung's Android build.

I wonder if it's carrier specific? I have an AT&T/i337 and have no issues connecting to any wifi anywhere, even after the update to 4.3. I see a wide range of routers from home to commercial units.

I don't doubt your issue at all. But am reluctant to label it a Samsung issue.

It was there on the SGS3 for a lot of people as well.

I agree, it's a robustness issue and belongs to Samsung.

For whatever that's worth.

Nope, I'm on AT&T and definitely had WiFI issues after the 4.3 update. Curiously not before the 4.3 update. And a factory reset fixed it. That argues strongly for the Samsung software.

My WiFi turns on and off completely on its own as much as a stoplight changes. Others with non-Samsung smart phones don't have the problem with a given WiFi location. This is a main component of my WiFi dysfunction.

What it is good at doing is using up data and draining my battery.

Until shown otherwise it's all Samsung....I can't blame AT&T or specific WiFi routers.

Here's a video of what my wife's phone is doing. I'm new to Android...we've both had A**** phones for the past few years. Talk about a change in operating systems...

So far I've updated the firmware in my router, I've reset the phone, I've changed settings based on what I've found online and nothing seems to be working.

In the video, the phone connects to my wifi at the start of the video and in 1 minute and 15 seconds, it connects three times. Each time it drops wifi, connects to 4G, and then connects back to wifi.

Sounds like that could possibly be where the phone thinks the wifi is weak and transfers to mobile data.

BigRedGonzo says, "try unchecking "Auto Network Switch." That keeps my phone attached to the WiFi network at the office, even though the internet drops frequently. If I have "Auto Network Switch" checked, I get messages all day long telling me the WiFi has been turned off because of poor internet connectivity."
W-Fi problem with S4

Don't know if that will help or not, but may be worth a try.

Interestingly, my WiFi works best signing in via my newly installed Firefox for my internet.

Some of you other unlucky Samsung Galaxy S4 users with similar WiFi woes as me might also find this useful.

Yep, that is what I posted in Wi-Fi issue. This has solved the issue for me.

It sounds like the issue most of you are having is well covered by the fixes mentioned in the posts above.

I'll mention an oddball but potentially-effective thing to try if you experience problems related to wifi on any of your devices or computers- power cycle your wifi router (turn it off for 15 seconds and then turn it back on).

Here's how I discovered it. We seemed to have lost internet to all devices so I called the helpline of our ISP. They suggested to power cycle our router... I thought it was another silly waste of time but tried it and it worked to restore our internet. I'm now finding it cures a lot of other oddball intermittent things related to our connection. For example sometimes I can't connect from my phone (ES file explorer) to Windows 7 shared network folder on my pc... it's cured by power cycling router. Sometimes I get periods of frequent disconnect (page did not load)... cured by cycling router.

It may not apply to everyone but for us it is an easy fix to most wifi problems (power cycle the router). We have a Belkin N150

Oh, it's definitely for real. I had an Amped Wireless router with that problem. What was happening was that the DHCP never released an ip address… even after the device left range. After awhile, it just ran out of addresses, and rebooting (power cycling) it was the only way to reset/renew the address pool. The problem was eventaully fixed by a firmware upgrade, but it was a moot point, because I switched to an Asus RT-N66U about that time so I could have 5GHz availability. I've never had an issue with any Samsung device using the Asus.

I have the same issue I thought I 'm the only one with the WIFi issue. My s4 doesn't stay connect to my WiFi. I have a Belkin N100 router.

Auto Connect is not checked...the box can be seen in the video. oddly...I "forgot" my 5g wifi network and connected the phone to the 2.4 and it seems to be working much better.
