Location services has an option "Use Wireless Networks" where "Location determined by WiFi and/or mobile networks". I usually leave Wifi turned off unless I'm somewhere I know has good quality Wifi as my plan includes 3GB of data per month.
My problem is that if I am somewhere without GPS reception and an app calls for location the phone then turns on Wifi briefly to find a location. This of course disconnects my HSDPA+ session which interrupts internet and makes whatever app I just loaded either take forever to load as it then needs to find a new connection (via WiFi); or the app complains that there is no internet and it exits.
Not all apps do this (some are better behaved).
I need to leave the "Use Wireless Networks" option on so that if there is no GPS the cellular network can provide a rough location to the app.
Is there some way I can have the "Use Wireless Networks" use cellular for location but not use Wifi?

I purchased a vibrant used from someone off craigslist to use on t-mobile. However, I do not have a 3G data plan as of this moment. My question is does the data connection factor into the calculation of your location? or is it entirely determined by the GPS signal?
Gps can be used standalone but you do need a network connection to use google maps

aGPS data downloads over the T-Mobile data network (won't over WiFi, same with other T-Mobile phones oddly).. so you will only get very slow standalone GPS.

However you (the OP) might try the app "GPS Status" -- in its tools menu there is an option to download a-gps data, maybe it can be done over wifi.
I seldom have my SIM in my Vibrant right now, and recently I've used the GPS some on wifi. I don't know whether it's cached from when I did have my SIM in it, but GPS Test *does* seem to be using AGPS data of some sort; when I start it up it shows a bunch of sats with 0 signal (which I assume is what AGPS would provide).
Hi, I have problem with wifi conection. I'm normally connected to wifi but I don't have internet access.
You might think that you're really connected to a wi-fi, to verify your wi-fi connectivity, do this steps.
You must turn-off first your existing wifi connection before proceeding this steps!
Using your Samsung Galaxy Mini, go to Settings > Wireless & Networks > Wi-fi Settings, turn-on your Wi-fi connectivity there.
If your SGM can scan wifi connection then it might give you several wifi networks.
Below Network Notification is Wi-fi Networks, you can see a list of available wifi networks there and you can clearly say that you are NOT really Connected if the status of each Wi-fi networks is giving you this message. "Remembered, secured with WPA/WPA2PSK or secured with Password".
To sum it up, you're SGM can scan wifi networks but it cannot successfully connect because some of wi-fi networks are secured with Password. Just ask for it's password, otherwise, find a wi-fi network which doesn't have a network password.
What if you're already connected but still, cannot access internet surfing..
Go to Settings > Applications > Manage Applications.
Under Manage Applications, point to All tab and find Internet on the list and Opera (if you have) and Google Play Store (formerly known as Market) and Open each Applications.
for example: Open Google Play Store then click Clear Data and Clear Cache then repeat this steps to other applications which I mentioned above.
Hope it helps

Anyone know of a way to turn "Scanning" for wi-fi networks off after you are "Connected" to a wi-fi network thus saving battery? Turning off "Notify me" does not do it.

I think it stops scanning once ur connected and leave the page..if u reopen the WiFi page it scans then stops,at least in mine it does..

From what I've read, this seems to be the way it works. Bottom line it will scan every 4 secs or so while you are on the settings page in case you are trying to connect to a new network, then revert to wifi.supplicant_scan_interval from build.prop when not on the settings page. It's not clear that it has much of a battery impact whatever you set it to. I leave wifi on all the time and whether I am on wifi all day or out and about on lte my battery usage for wifi is negligible.

Hi everyone, I have a question that i can't quite seem to find an answer to any where i look.
I am a recent android convert, i had ios on my iphone and ipads for many years. I use a wireless hard drive that has its own wifi signal, which i connect my devices to. The problem with doing this is that the device thinks then that it should get all of its internet from that wifi connection, which of course, being a hard drive, it does not have.
To get around this what i have done is go in my IOS configuration and remove the "default gateway" or "router" or whatever you want to call it (depending on your networking background), and then iOS knows to go ahead and not use wifi and continue to send any non local traffic over LTE.
My Samsung Note 5 doesn't seem to want to do this. First thing, when i try to remove the router/gateway from the ip address configuration in wifi, the "save" button is grayed, meaning i cannot save a blank gateway. I located an app on the app store called "wifi settings" which was suggested to use to set the router to nothing, but still this did not work, really what it did was save a 1 in the router/gateway field and caused nothing to work, not even local traffic.
The Note 5 has a "smart network switch" option which is apparently to detect a poor wifi signal and switch to LTE, if i enable this, the phone does realize that the wifi connection to the wifi hdd doesn't have an internet connection, but terminates the wifi connection, thus killing my connection to my hard drive.
My question, does anyone know how to configure the wifi on android to access local resources via wifi while still using the 3g/4g connection for internet traffic?
Any help would be appreciated. Thanks much.
Galaxy S10+, latest Android update from my carrier.
While hooked to any Wi-Fi that doesn't serve internet (my camper accessories, for example, are controlled by the wifi, but serves no internet connection), it allows very little data to function until I shut the wifi back off or end the connection to the camper.
I have my settings set up to keep mobile data active and also have aggressive wifi/mobile data handoff enabled.
Does anyone have a fix or any suggestions? It's really frustrating as I a few other devices that require a wifi connection to control but don't serve internet access.
Thanks in advance!
