Wifi Still Scans Even when Connected? - Samsung Epic 4G Touch

Does anyone know why wifi has the need to continually scan even though I am already connected to a network. When in wifi settings it says Wi-Fi networks then *scanning*. Any way to disable this, trying to save a little battery life.

Seems like a SamSung phone thing. Mine has done that since day one.

It only scans when you access that function. As someone posted a while back, it's sort of like the refrigerator light coming on when you open the door...

[Q] Any apps that can enable GPS by text message?

Anyone know of anything? I've spent a good part of my day trying to find an alternative to Mobile Defense with no luck. I would rather not put all my information out there and txt messaging would be a good alternative to using an internet connection. SU access is no problem.
So you want to turn on your GPS by sending a text message to your phone?
check out the app on the market called wheres my droid, its free and does what your asking i found it last night so i am not sure if it does what it says or not but its worth checking out.

Yup, that way if I ever lose it somewhere I don't have to worry about the GPS being off. If that happens you're stuck going by what towers it's pinging and that will give you a 3-5 mile area.

Where's my Droid is what I was going to use to get it's location. Only thing is the GPS has to already be on for it to work.
ah i didnt know that, like i said have only had it since last night, but id say that with SU access you should be able to do anything so im sure someone with more knowledge then me can come up with an answer but i doubt that it cant be done.
I've read (and I could be wrong) that leaving GPS on all the time won't kill your battery like you'd think. It only uses resources when it's actually getting GPS data, which is signaled by the GPS icon in your notification bar. I've been leaving mine on all the time for weeks, and I still get 36+ hours of normal usage just like I did when I was clicking it off all the time except when I wanted to navigate something.
And then you could use Where's My Droid's GPS feature.
Try Lookout and see if it suits your needs.

Is there an app that automatically disables and re-enables wifi on a set scheudle?

I use "Wifi Auto Toggle" now to turn wifi on/off when I forget about it, but I have a problem where my wireless will randomly get stuck "authenticating" with my school's WPA network so it will appear to be connected without any problems, but you won't be able to access the internet with it. This means that Wifi Auto Toggle won't think to disconnect it, so it will sit there until I pick up my phone and realize that I need to reconnect. Any suggestions are welcome!
You can use tasker to turn the wifi on and off depending on time, location, whether the phone is plugged in, etc. It's confusing at first but it works wonders!!

I'd prefer an app that isn't $6... Also, it just needs to toggle the wifi on a set schedule (say, every 15 minutes). That way I could easily turn it on or off depending on where I am.
Saw an app call Modus Operandi in the main app forum that might do what you want (kind of a free Tasker alternative). I use Tasker though so I don't know how well this app works...

I user Timeriffic. It's free and works great.

It's easy to use too.

Wi-Fi Not shutting off and keeping phone awake?

Despite checking off Never, my phone is keeping Wi-Fi active and the phone isn't sleeping. Is there a way to fix this glitch? Also despite having an airave at home, my device shows constantly under the battery setting that i have no mobile signal. This is possibly making the phone search for signal, and explains why it often find a weird roaming signal. Anyone know any fixes?

Yep, what this guy said.
It was bugging me for a while too, not sure if its a feature of 4.1.x Android, but my understanding is if the device senses a Wi-Fi connection it turns on the radio and might ask you to try to configure. At the office, while driving, etc etc.

Ive disabled it countless times... it turns itself back on. There are other tiny little hickups Im having. The first device was flawless until an App Installation went corrupt and ruined it... Now I actually have a minor dud. Gotta try for "third times a charm"...

I just noticed that too. It does, or seems to want to turn itself back on. Pretty lame of Sprint to do this if you ask me.

It is a feature of the OTA Samung update that put your device to LJC .. After you installed the update whether it was Automatic over the air or even manually once you device said Update installation successful then a box was up that you had to hit "Ok" and it was the box that read about the new Sprint Optimization option.
So, if you have the wifi on in the house it still causes a problem? Or is this an issue when you are out and have the wifi off, and it still searches for wifi location no matter what killing the battery?

[Q] MOAR wifi question

Benn running MOAR v2.2 for a few days and love it. But I've noticed something when wifi is turned on. If I'm on the wifi settings screen, I can see it scanning about every 5-6 seconds for new wifi signals, even though I'm signed into my home router with a good signal.
Network notification is turned off. I'm running the stock kernel.
Couldn't find anything in the moar thread about this.
Wondering if it's just me or if others also have this happening but just haven't noticed? Because you wouldn't know unless you're on the wifi settings screen with wifi turned on.
Can anyone verify this?
Any ideas on how to make it stop constantly scanning?

Well, this has nothing to do with your rom or kernel...thats just how the wifi is implemented. And you cant turn it off, unless you want to use wifi at all that is, this is to make sure you still have wifi access and to update the wifi networks that show up listed
You can make the scan interval longer by setting the "wifi_supplicant_scan_interval" (or something along those lines) to a higher value in your build.prop (located at /system/build.prop)

Thanks for the reply.
I also eventually found the answer by searching (of course), and the moment I found it, I had a horrible thought. OMG did I get a furry little animal killed?

I've been doing tons of reading here and I've seen some devs saying, "every time someone asks a question that could have been answered by searching, a cute furry animal dies." lol
Reminded me of an old National Lampoon cover with a picture of a dog with a gun to it's head. Next to the picture it said "If you don't buy this magazine, we'll kill this dog!" One of the best covers of any magazine EVER. I cant post pics yet but google that phrase and you can see it.

WiFi not connecting, reports two slow?

So this has happened to me at home and work but it's not consistent. Some times when I try to connect I get a message on the WiFi connect that says "Network disabled because Internet connection is slow" (see picture). Any idea what criteria is used to determine this, and is there a way to over ride it?
I'm at work right now and I just got kicked out wifi due to too slow lol.. but at home I have not got it yet.. maybe too much people at work using the wifi network. .
I setup my home network to have separated name (SSID) for 2.4Ghz and 5Ghz Network.
When I connect to the 2.4Ghz channel, no problem.
At the same distance, like 6 inches away from the router, when I connect to the 5Ghz channel, my 2 Galaxy Note 3 shows the same "network too slow" error and it will drop the connection.
This is one of the many reasons I returned my GSN 3
I also experienced another WiFi error.
At work, I can connect to the WiFi network with the WPA password provided, on my HTC One with no issue whatsoever.
When I tried to connect to the same network using the Note 3, it keeps telling me I have to "sign-in", when I click on the browser to "sign-in" (like those Free WiFi you can get at the hotel), there is no sign in page (because there is none) and brings me right to Google.com.
After that, the connection will last for 30 seconds or so and drop off.
The one I got initially and the replacement, both have the same issue, and I did inform T Mobile before I return them back.
4.3 problem? Samsung's problem? I don't know... All I know is I will wait until they resolve all these before I will reconsider getting this phone.
I spoke to them on same issue. Got new phone and they working on updating the WiFi drivers.
NOTE 3
Here is the fix for this it worked for me try this....
Go to wifi advanced settings lower left corner then uncheck auto network switch. Then check the box that pops up that says don't ask again. This should fix your wifi connecting issue...

So far yes. Not a 100% sure though because the problem was not consistent. Sometimes it would connect sometime give the message. So, I'll keep you posted if it comes back.
Not trying to say your post isn't serious enough but we all who are having this problem on a consistent basis need to make a thread about this and just not take anything for an answer, but to give people somewhere to complain about this & hopefully bring more attention to this because there is nothing that is fixing this issue. The only thing that will fix this is Samsung or a Dev on a custom ROM hopefully. If you uncheck the options in advanced settings, it just stops the pop up from coming up telling you the connection is to slow & dropping you, after unchecked it dont drop you but while still showing you a full connection it will not do anything data wise, connect to the internet, switch to a different site, no facebook, no twitter, no market etc..... Nothing, you dont get dropped you just cant do anything. I hope my anger dont make anyone think Im arguing with anyone in here and their opinions, we all have this problem and are trying to help eachother, im just poitning out that those who are thinking this is fixing things its not, its just stopping the pop up. I am very frustrated this is happening on a brand new phone i waited this long for and paid as much as i did for. There should be a freaking petition started for this cause its just wrong.
Works fine for me my wifi never disconnects now after unchecking auto network switch and always scanning... Idk what to tell you guys that are still having the issue because I had the same issue when I first got the phone too...
Maybe try forgetting the network then reconnect after unchecking those settings and reboot...

Not all phones are created equal. Samsung needs to change the wifi drivers on the phone or a dev needs to take note 2 drives and add them to a custom rom.

I posted this in a different forum also but figured id post it here to. I just got off the phone with Samsung & they told me its not a major reported problem, wtf, lol? Everyone i know who owns this phone has this problem with it sayin internet connection to slow and booting them off, even with full signal. Im on my 2nd phone now & have the same problem. They tried telling me to go in to the wifi call settings & turn off wifi calling preferred, & i said why? Even though it's checked I have it off. I said seriously? what is that going to do for a wifi signal problem, lol. It's not my wifi calling it's my full wifi signal. I can tell this is going to be a huge problem & im returning my phone, 3rd time now, for a new one today, if i get the same problem, almost positive i will, im sadly going to have to return this phone & just get a refund instead. & that would really suck. Maybe i'll try a black one, but im sure it probably happens on that one to, lol.
I have been having this problem also. Turning off "Auto network switch" in the advanced network settings allows the phone to hold on to the connection, but it is completely unstable. I tested the connection using iPerf and it was all over the place. I can post screenshots when I get home later if it helps anyone. Samsung definitely needs to step in here.

Samsung could careless about us. They sold the phone to TMOBILE not us. Or whatever ur using. Everyone needs to complain to the big 4 major company. Then if they get hit hard then they can light a fire under Samsung butt.
