Question about Wi-Fi - Nexus 5 Q&A, Help & Troubleshooting

Hi. I'd like to keep my phone connected to a local Wi-Fi network so that I can access a server on that network. However that network doesn't have a working internet connection. Can I keep my phone connected to Wi-Fi but let it use 3G for internet connection? Thank you

Normally when the WiFi is connected to a network the data is automatically disabled so I'd say no to your question.
But Super Download might help.

Could WiFi always scanning be used in this case perhaps? Try it by disabling your WiFi but leaving that option enabled under the Advanced settings.

Of course it wont work to use always scanning. It even says scanning in the name, meaning it simply allows the locations service to turn on wifi briefly in order to see local networks so it can use them to locate you.
What OP is asking for is not natively supported, and would probably require a bunch of modifications on a deep level.

wifi & Edge/3G

Here's a basic question about the HTC Fuze. If I'm using the Edge network and I turn on wifi, thereby getting a faster connection, do Fuze applications default to the faster connection or do I somehow have to turn off the edge/3G connection specifically. I know I should be able to tell...
I usually have both wifi and edge/3g off. When I need data I turn on whatever i need. You do that thru the communication manager.
I think the real question is with both the Edge/3G on and Wifi connected, where will the data transfer? Through the cell network or the WiFi network?
the icons on the top bar of my device display clear which connection is active
with a data session
when one is active it's the only one being used to access data from the internet
It's possible to have both OTA and wifi active, which is what the OP is driving at. IME a program will find and use the faster connection at startup, but if the program is running on OTA and you connect wifi, a lot of programs won't switch to the faster connection. Again, that's just my anecdotal experience - it's hard to tell which connection is being used in real time.

[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.

Gear S2 Wifi Authentication

Am I completely missing something here? Why can I not get my watch on our wifi network. It requires authentication. But if I make sure that bluetooth is enabled. It scans the network and I can see it. However if I try to connect it tells me authentication errors. But I can not find a single spot to add login or password or any authentication option. Only options to connect to wifi are AKA and SIM.. How the heck do I get this thing on a wifi network??
Try disconnecting from Bluetooth and allow your phone to locate your wireless network. You should now be prompted for SSID and password. I personally had a hard time entering a complex password as part of WPA2 requirements. So I enabled WPS on my router and used it to connect my S2 fairly quickly. Furthermore, I don't believe it will use Wifi as long as you are connected to the phone via bluetooth. It can switch to wifi if you are out of the range of bluetooth or choose to use the watch in standalone mode.
Sync your saved wifi information from your Samsung account to your watch. It will log into the wifi network. I had the same problem and after syncing with my phone's saved wifi info it says it's logged in but it will not transfer any data on that wifi network.
Works fine on my home network that only requires a password, but I want it to work everywhere I can connect to wifi with my phone.
Haven't found a solution yet.

Force Android to use Mobile Data when WiFi Connected but has No Internet

I've been plagued by this issue for 15 years. The title says it all, but here's the deal:
When my WiFi is on and manages to connect to a nearby WiFi hotspot that has no internet connection (or requires authentication), my Android phone loses all data connectivity, even though there is strong 4G signal. It's trying to connect to the Internet through the WiFi, which has no Internet connection. If I manually turn off WiFi, then the data connection is re-established over mobile data. Why doesn't it automatically switch to mobile data in this situation? Is there any way to force it to do so? My phone isn't rooted, but I do know how to root so I'd be happy to try anything.
In particular, this happens constantly when I'm driving in the city. The phone picks up all sorts of hotspots that require authentication, so essentially they are all dead ends. Manually turning off WiFi isn't a real option since I'm driving. I want the phone to automatically detect that the WiFi doesn't have a connection to the Internet, and switch to mobile data automatically.
I've read about 15+ threads on this, some of which go back 10 years, and none of them have a real solution to the problem.
IMPORTANT:
I am not looking to exclude specific WiFi connections/networks. It should work on any connection that has no internet connectivity.
I am not looking to set this up for specific apps. It should work for the entire phone's data connection.
I know that this is a huge problem for a lot of people, so there must be a solution. Please, I'd apprecaite your help.
Please answer only with solutions to the problem, not "why do you want to do that" or "that's impossible" answers.
