Problems with WiFi? - Samsung Infuse 4G

Is anyone else experiencing issues with this phone not always connecting to remembered wireless networks? When I'm at work I use the AT&T network through PSU and previous phones would always connect to them whenever in range. This phone shows that it sees the network signal but doesnt auto connect, I have to turn off and on wifi. Am I the only one?

I've had this problem a few times already.
Will keep an eye on it.

I have had problems only on 5GHz networks. 2.4GHz networks are fine for me.

I'm also seeing that it's actually connected - showing good signal strength but when I try to access the internet on any app it time out.

I've had the same problems. It will see my network but not auto connect. Then when I tell it to connect it acts as if it doesnt know the password. If I turn wifi on and off, it then connects fine on its own.

WiFi won't disconnect when out of range

Hi all,
I have HTC One S from T-Mobile and noticed a big problem with my WiFi connection.
My phone will connect automatically to the wifi network in my home/work correctly, but when I leave and am clearly out of range of my wifi network (say, a km away), the phone still claims to be connected to the network, but I of course have no actual connectivity. The signal strength it reports has varied, from full strength to just a few bars.
I try giving it a minute, but it seems stuck and refuses to officially disconnect from the network. The only way to fix things is to toggle my wifi on and off, at which point it goes to mobile data since it can't find any wifi networks to connect to.
The thing is that I use Wireless Bluetooth headphones and since I started using my new phone, the signal drops (I believe it is because of the Wi-Fi not disconnecting from the network and is causing disruptions to the bluetooth connection).
Any ideas how to resolve this issue? Thanks.

[Q] Wifi and Mobile data

I have Nexus 5 for over a week and waiting for case and screen protector. I left the plastic piece stay on the phone until the day before yesterday. I love the feeling of touch screen without any film or protector on it. I am learning this device.
I have router in my office powered but not working anymore, therefore there is wifi always on but not working anymore. Everyday in the morning, when I am in my office, the phone will detect that wifi auto, of course there is no signal. My mobile data is on all hte time. I have to turnoff wifi from the phone, otherwise I can not, for example, surf internet and check email. In the other words, no internet connection even mobile data is on.
So my question is: why the phone can not pick up mobile data automatically even there is a wifi? I was scared when i first had this problem because I thought my phone is not working. Is there any setting I can try to let the phone pickup signal from either wifi or mobile data automatically?
I'm interested also. Nexus 5 has a difficult time negotiating a signal when the signal is weak. At home, I get a higher powered signal on 2G so I keep it there. Today I noticed "no signal" and emergency calls message most of the day. (hubby's iPhone 4s is on the same service and he's getting the signal). I turned off Wi-Fi (which works perfectly, btw ) and phone signal connected. Treated it several times. Sounds like a hardware defect.

Your wording makes the question a little confusing, but I think you are saying your office router is turned on and available for WiFi connections, but has no internet connection itself to pass through to your phone.
Your phone connects to that WiFi for data, but can't reach the Net through the router. Meanwhile, you could get data through the phone data plan, but that does not work unless you turn off WiFi.
This normal. The phone is designed to use WiFi for data if a connection is available that you have authorized the phone to make. It won't use the phone data plan if connected to the WiFi, as you see. It cannot tell that the WiFi router is not connected to the Net.
I suggest you go into WiFi settings, click on the "ghostly" WiFi entry and tell the phone to forget that connection. From then on, the phone won't connect to that router and will use phone data plan.
What you would prefer would be for the phone to use its data plan as a fallback option, in case it gets hooked up to a WiFi network with no internet access, like at your work. Would be nice as an option, but not the way things work currently.

To prevent overage for users that may have limited data plan, the device will always try to use WiFi when enabled. If it can't connect to a WiFi network, it will look for the mobile data if enabled.

In your case, since WiFi is "available", there is no setting on the stock ROM that will tell the device to connect to mobile data instead. Think about it this way - your phone is connected to the LAN using the WiFi network. It can reach the gateway, and has a valid IP. It doesn't care about whether it has WAN connectivity or not. So, it assumes that you are connected, and have connectivity.
You could look for apps on the play store that will actually check for WAN connectivity and if not available, disable WiFi (so that mobile data is used instead)
But, the part that I don't understand is this: If you don't have WiFi available, why do you even enable it? Turn WiFi off (disable wifi scanning in advanced settings of WiFi as well), and let mobile data take over instead. Or do you need WiFi elsewhere (say, at home)? If so, there are apps like Tasker that will let you set up profiles to enable WiFi when you are at home, and disable it when you are at office or other locations.
Thanks all for your very helpful reply. Sorry for my poor written English.
My office router does not function properly and I am to lazy to power it off, so my phone still can detect it but of course there no internet access from the router.
I now know I just need turn off wifi from phone and the phone will pickup mobile data auto.

Work wifi

Hey guys I still cant connect to my works WiFi.
From the WiFi settings menu. When ever I try to connect it does nothing but says "saved"
My nexus 4 and 7 never had issues. IPhone connect just fine and other people with android phones either connect or can't
I need help, and the WiFi and whole network gets power cycled every weekend. It is a large WiFi network with the same ssid broadcasted from many repeaters throughout the plant
Were you able to solve this?

[Q] WIfi disconnection on certain networks

Hi everybody!
I'm using the latest build of CM11S (KTU84P), When i'm connected to my home network (using a Dlink 6740H1 router) the connection to the wireless network will stop after a few minutes.
The wireless icon will become orange and there will be no data transfer what so ever. When I'm connected to other wireless networks the phone works fine and does not disconnects.
The "Keep Wi-Fi on during sleep" option is checked and the "Avoid poor connections" is not checked, further more I've tried flashing franko kernel but it didn't change anything.
Other phones in the house (HTC one X) does not seem to suffer from the same problem, did anyone ran into this issue before?
Thank a lot!

*cough*
i have a similar problem with the latest rom.. KTU84Q (38R).. my wifi wont connect to my home AP.. never had this issue pre 38R.
Did you find a solution to this problem?
I have the same problem..
I am also having this problem.
I'm having the same issue with our router at work. Have you tried setting up a static IP for your home network?
problem with wifi: i connect to a network (password) and everything is ok until i go out of coverage. when i go back in area, the phone scans/finds the saved network but does not connect auto, i have to turn off/on wifi and then it connects.
on all networks, dosen't matter the router model or type of network (password or free, static/dinamic IP)
Try deleting all the saved Ap and re-add them. Seems it worked for me, now it connects to Wi-Fi. I had many saved from trips (hotels, pubs Wi-Fi with password and many free)

Wifi roaming bug is back on S7

I have two wifi APs with the same SSID and it will stick to one of them with next-to-useless connection while standing near the other one. which would have much better connection.
This works fine on my Nexus 9 tablet and even better on my iPad and my wifes iPhone..
I tried some possible workarounds like Always allow wi-fi roam scans but I didn't see any effect.
This fix for SG3 might work but i havn't rooted.
Even more solution suggestions
Doesn't this bother anyone else ?
wifi has a bug in 6.X and its been talked about before.
my problem some times when i want to connect to another wifi it connects for a 1 sec and then drops it
i turn off wifi and back on and it will connect
i'm trying the app "Wifi roaming fix" but i think it causes the wifi to disconnect for a couple of seconds when it switches.
Strange that this seems to be of no interest to anyone. Is there indeed nobody who is using one or more WLAN APs in addition to his/her WLAN router? I can't believe that.
I have two APs (Main router and 2nd router as AP) but not for more coverage, my main router pushes 5GHz wifi, the second AP pushes 2.4GHz for older clients that can't connect to 5GHz
The 5GHz router is placed on a wall in the middle of the house and the entire house has great coverage so no need for more APs
I have more APs in my house with OpenWRT and 802.11r aka Fast Roaming configured and roaming between all my APs is working perfectly with all my devices.
Note 10.1 2014 Wifi, S7 Exynos and all other also.
With APs configured as "normal" ap with the same SSID and key i had the same issue as you mentioned.
I think your phone dont know that it could roam between your two APs.
If you could not run OpenWRT on your APs for 802.11r, you could try to enable WDS on both APs even if your APs connected by wire.
