I've got local wireless network with no internet access, and I use static IP of my router to connect from Android device. When 3G(HSPDA disabled) Android phone see and connect to the router in WiFi network (ssh), however when I turn on 3g, my phone cannot see WiFi router. Is there any workarounds for that without disabling 3G service while using local WiFi in app?
I think you might be suffering from an Android optimization. Try to go to the WiFi settings, hit the menu key and choose "Advanced", and uncheck "Avoid poor connections".

I have a webserver that is running on a network that is not connected to the internet.
The webserver serves up a website.
When I connect an android phone to it, I am able to run the website that is on the webserver
But with certain phones that are running Android 11 I need to disable the mobile data on the phone before it will try to access the website over wifi. It seems the phone will not try to request the url on the wifi network because it doesn't have internet, so it defaults to using the 4G/5G Cellular internet connection. This is too bad, because I would like the phone to use the wifi connection.
I would think that perhaops I could "force" the phone to use the wifi connection by typing the IP address in the browser's URL bar (eg. http://192.168.211.1/index.php), however it seems that even with the "local ip" it will still try to use the 4G/5G network instead of the "offline wifi" network.
The only workaround I have found is to disable moblie data on the phone, but this is not ideal.
I would think that some IoT devices would have an offline webserver used for configuation/control.
Is there a certain port or settings I should be using?
Is there a designated port that the browser/OS would expect to be on an offline network?
Basically, how can I make the phone use the wifi, even though the wifi is not connected to the internet?
Thanks so much for any pointers!
Say I have a laptop (Windows 10) and an Android phone. The laptop does not have an internet connection and the Android does not have an internet connection.
I have an Xamarin app that uses a C# Web API that is deployed to the laptop (for testing). How can I connect the mobile to the laptop without any form of internet connection? I believe I have two options:
1) USB cable
2) Bluetooth
I believe I have to install a wireless hotspot on the laptop and then a reverse tethering on the Android.
Have I understood this correctly? Do I have to do this regardless of whether I use a USB cable or a Bluetooth connection.
Tethering is the name given to a mobile that acts as a hotspot. It make use of a network interface (Wifi, Bluetooth, USB port acting as Ethernet...) to share internet connection through the selected interface.
As you'll note I'm not incluiding mobile data in the list. Mobile data is used to connect to Internet. So your mobile is capable of connecting to internet via mobile data and share it via any other interface, i.e. Wifi, Bluetooth and USB (Ethernet)
At least in my mobile im able to just enable Tethering configuring it from Settings -> Wifi connections -> Share internet. Here I can switch on/off the desired interface: USB, bluetooth or Wifi. I can enable just one, both or even all of those
As far as I know a Xamarin app is an android app that embeddes a website and, optionaly but highly common, uses a server as an endpoint (your laptop in this case), also known as API.
So as you ask you don't want to have internet connectivity, all the connections must be made in a local network. To do so you could just enable tethering and turn off mobile data on your mobile. Then on your laptop, connect to your new network over wifi, enable ethernet or connect via bluetooth, depending on your choose.
Of course, you'll have to handle firewall on your laptop to ensure connections are made successfuly. But you should be able at last to ping each other.
I'm developing an android app which deals with network connection. If my device is connected to a normal WiFi network then it works properly, but if I connect my device to a WiFi network having proxy settings then my app does not work. Those network calls doesn't work if WiFi has proxy settings.
Is there any solution for detecting whether WiFi network has proxy settings?
Setting static IP Address(192.168.55.155) on android device, results in its WiFi connection not working (no internet).
If its DHCP on the android device, WiFi (internet) works. The Gateway on the device is pointing to Wifi Router.
I have a few android devices on the WiFi router. I need to know the IP Addresses of these devices in advance, so having static IP address is one way.
What configuration is missing?
You cannot give it a fixed address of 192.168.55.### when the router gives you one like 192.168.0.### but only 192.168.0.### also. Try 192.168.0.155.
Its easy, use an APP called Fing this APP allows you to watch all devices connected to your network and their IPs.
Since I am newbie in Android, I don't know how to connect Android (2.1 on HTC Desire) with PPPoE using wifi connection.
So Please anybody know solution, then kindly help me.
If you want to use PPPOE client with android, you have to first root your android phone, otherwise, the application will not work.
The other method is to use your modem in PPPOE mode rather than bridge mode. In Bridge mode, you have to have a PPPOE dialer installed to your device to access the internet.
In PPPOE mode, the user id and password are punched in the modem itself, so you have to just provide the wifi (if enabled) password and you are connected to the internet. But there is a trick, some ISP's modem do not work, when switched to the PPPOE mode and have to be re-configured again.
yes you can...
there is a App called WiFipppoe...

As far as I know, PPPoE would be how you would authenticate to your service provider. Wifi just acts as a bridge between the router and the wireless device. The router is what should authenticate via PPPoE. Your device should connect to the Wireless Connection, that would put you on the same network as the router, the router authenticates to the service provider via PPPoE over the WAN.
Wifi is just a bridge between your device and the router. Now some routers have Wifi built in, but its like a Printer/Copier/Scanner, 3 devices jammed in to 1.
