Android Support for Multihoming - Android Q&A, Help & Troubleshooting

Wondering whether Android supports multihoming, in other words, using both a Wi-Fi and LTE connection at the same time?
It seems not, that if Wi-Fi is connected then LTE is disabled.
If my Wi-Fi cannot connect to the Internet for some reason, I would like to be able to continue connecting to resources
that are local to Wi-Fi (and not accessible via Internet) and also access Internet through LTE.

Android Wifi Hotspost WITHOUT TETHERING

I want to host an INFRASTRUCTURE (not AD-HOC), otherwise known as a SoftAP (Access point) on wifi. This is possible with many applications, but they all want to use a mobile data connection. Is there any application that allows you to host a SoftAP WITHOUT a 2G/3G/4G connection? This is just for playing over WIFI between a samsung galaxy s3 and an older android 2.1 tablet. These cannot see AdHoc networks.
Anyways, I'm interested in any application that allows hosting of an infrastructure WiFi network without tethering to just host a wireless lan point.

I am also very interested in a solution/app like this.
A photo app (MoPhotos) will work with my EyeFi WiFi card to transfer photos from the card in my camera to my computer/Android device via Wifi.
Currently, the card has to go through the home router as that what it looks for to give it a IP Address and network to connect to the computer/Android.
If there is a way for the Android device to be a Wifi HotSpot without the mobile tethering, I can configure the card to talk directly to the Android, which would be *very* helpful when out and about.

[Q] Possible to route internet traffic through LTE but still access my wifi network

At home I can either be connected to wifi, which allows me to control my lights and access computers/NAS on my network. But if I'm connected to LTE I can download much faster.
Is it possible to be connected to Wifi but have all traffic outside of the 192.168.2.X subnet go through LTE?

[Q] trying to connect hotspot clients to local network

Is it possible to creat a hotspot that connects to a local network instead of the cell data? I connect several devices to tab 3 tablets in vehicles i would like to connect them to my network when they are at my facility. I would like to keep them in groups and have this work automaticly, maybe by using tasker to turn off data and switich to local network by location or time ect. (make hotspot a client on my local network)
normally the wlan connection to the wlan-router is turned off when wlan-hotspot is used in Android.
why not connecting the devices directly through wlan-router to the local network? or a wlan repeater if the signal is too weak.
Or you could connect the hot-spot to a PC via USB , which in turn is connected to the network.
AFAIK only Miracast can maintain 1 connection with the router and 1 connection with a end device concurrently. But I guess that's no helping in your case.

WiFi Host (Hotspot) and Client At The Same Time?

Has anyone tried using the V30 as a WiFi host (hotspot) to provide internet connection (of cellular connection) to other WiFi clients, at the same time the V30 is a WiFi client to a different WiFi network not connected to internet?
I'm thinking about using my V30S as WiFi hotspot, while simultaneously using the same V30S as a client accessing a NAS on another WiFi network without internet access.
Any info appreciated.

Unfortunately no, to the best of my knowledge. Our phones only have one WiFi radio that I'm aware of (dual band is not dual radio), so only one mode at a time.

Question Wi-Fi Signal Relay Function?

Hello PRO-I users, greetings from Korea.
I've been planning to purchase a Pro-I device, and I wonder if this device has a Wi-Fi relay function, i.e. mobile hotspot with Wi-Fi signal.
The problem is this; in South Korea there are lots of carrier-based Wi-Fi spots that requires EAP-SIM or EAP-AKA authentication to connect, which makes devices without specific SIM almost impossible to connect to secure Wi-Fi connection. In select Samsung and LG(RIP) devices there is a function called Wi-Fi sharing, which establishes Hotspot connection from Wi-Fi signals(NOT from 2G, 3G, LTE or 5G) under the device's hotspot name.
Example) Samsung Galaxy Note9(N960N)
1) Connect carrier Wi-Fi(KT WIFI)
2) Set device SSID as NOTE9-WIFI
3) Turn on Wi-Fi sharing
4) Turn on Mobile Hotspot function
5) Use my PC to connect NOTE9-WIFI, and connect to the internet with KT WIFI signals
Since I use quite a lot of non-SIM devices on the go, the availability of this function would be quite crucial. I've been searching high and low and I couldn't find a single clue of this.
Owners of PRO-I device, I humbly ask you guys a favor to find if this is possible. Is it possible to turn on mobile hotspot function with Wi-Fi connection?
Hi.
Got mine yesterday ... answer is a negative, unfortunately, as soon as you turn on the wifi hotspot, you lose wifi and it switches to mobile data.
JP.
