Wifi Hotspot No Internet

[Caleb Nelands]

Im trying to play a video game with my friends that requires a local wifi network that allows UDP broadcasts. The dorm wifi doesn't allow UDP broadcasts, so I'm trying to set up my laptop as a hotspot. Windows 10 by default allows you to share an internet connection over wifi, but you must have an internet connection to do so. Sharing the wifi connection results in a lot of problems such as constant disconnects, and I don't have access to an ethernet connection to share. Is there some way I can set up a wifi network without actually sharing an internet connection?

1.) Open an elevated command prompt. Win+X and choose CMD (Admin) OR type in "cmd" or "command prompt" into Windows Search by typing into Start Menu and then right click "Command Prompt" and select "Run As Administrator"

2.) Check if your system is capable run this command: netsh wlan show drivers. Scroll down to Hosted network supported. If it saysYes you are in luck; if No there is no easy alternative and don't continue.

Replace %ssid% with your Wifi or "Hotspot" Name or SSID. E.g. ssid=MyGreatHotspot. Replace %pass% with your Wifi or "Hotspot" Password. It must be 8 characters long at a minimum. E.g. key=strongPasswordsAreWEAK.

4.) After that run the command, netsh wlan start hostednetwork, to start the "Hotspot" broadcast. Right now you can play without internet connection after all devices connect. Remember to check IP addresses of all your individual devices in order to connect to each other. The hotspot's IP Address usually is "192.168.137.1".

5.) Open Run (Win + R) or by searching for Run and enter in ncpa.cpl, then press Enter. A new adapter has shown in the screen it should say something along the lines of "Microsoft Hosted Network Virtual Adapter". (Optional if you're OCD, rename that one if its says "L.A.N Connection* 15" or rather to like "Hotspot"). Right click the Internet Connect Source you want to share internet from and choose "Properties." Go to the "Sharing" Tab and checkmark or toggle on "Allow other network users to connect through this computer's Internet Connection." Apply, OK to save changes.

In case writing your own application is a possibility, have a look at the WiFi Direct API, which offers a legacy mode. Enabling the legacy mode will create a SoftAP with the specified SSID and password. However, specifying no password doesn't seem to be supported.

Have a look at the IoTOnboarding sample to see the legacy mode in action (and to have a better 'documentation' than what Microsoft officially provides): IotOnboarding/IoTOnboardingService/OnboardingAccessPoint.cs

If you are still using windows 10, then just open "Microsoft Store" from Start Menu. Find the app named as "Hotspot Lite" from there and just install it. Now open the app and configure the settings if you want or not. Done!!

1. Choose a hotspot device or hotspot plan: AT&T offers dedicated mobile hotspot devices, like the Netgear Nighthawk, or you can use the hotspot feature on your AT&T smartphone. Make sure you have a compatible data plan that supports hotspot usage.

2. Activate the hotspot: If you're using a dedicated hotspot device, follow the manufacturer's instructions to set it up and activate it with AT&T. If you're using your smartphone, go to the settings menu, find the "Personal Hotspot" or "Mobile Hotspot" option, and enable it.

3. Connect your devices: Once your hotspot is active, it will create a Wi-Fi network. On the devices you want to connect, search for available Wi-Fi networks, select your hotspot's network name (SSID), and enter the password if required.

4. Manage your data usage: Keep track of your data usage to avoid exceeding your plan's limits. You can usually monitor your data usage through your AT&T account or on your smartphone's settings menu.

5. Secure your hotspot: To protect your connection, make sure your hotspot is password-protected and uses strong encryption, like WPA2. You can usually configure these settings through the hotspot device's management interface or your smartphone's settings menu.

AT&T hotspot devices work by connecting to the AT&T cellular network and converting the cellular data signal into a Wi-Fi signal that can be used by Wi-Fi enabled devices. Here's a general overview of how AT&T hotspot devices work:

3. Device connection: Wi-Fi enabled devices, such as smartphones, tablets, and laptops, can connect to the hotspot's Wi-Fi network by selecting the network name (SSID) and entering the password, if required.

4. Internet access: Once connected, the devices can access the internet using the data from the AT&T cellular network. The hotspot device acts as a bridge between the cellular network and the connected devices, allowing them to communicate with the internet.

The Nighthawk mobile hotspot, specifically, is a portable device that provides fast and reliable internet connectivity by connecting to a cellular network and creating a Wi-Fi network for other devices to access.

The Nighthawk hotspot offers advanced features like long battery life, multiple device connections, and robust security options, making it a popular choice for users seeking a powerful and reliable mobile internet solution.

Mobile hotspots are a great way to connect all of your devices to the internet with a single data plan. These devices work by connecting to the AT&T wireless network and then broadcasting out a Wi-Fi signal. It's like having a home internet connection that you can take with you wherever you go.

If you've ever been a passenger on a long car ride, you probably know it can feel a lot longer without an internet connection. An in-car Wi-Fi device can use your wireless data to provide internet service throughout your car.

A mobile hotspot is a device that connects to a wireless network in the same way that a smartphone does. It then uses that connection to broadcast a Wi-Fi signal and provide wireless internet to nearby devices.

I've this same problem on iPhone 8 running iOS 13.1.3. My devices (Windows laptop, Fire TV, Android phone) can see the iPhone hotspot and connects to it but there is no internet connectivity thru hotspot, though i can browse internet on my iPhone.

Having same issues with my 8plus. Following step 10 worked except I only have internet on IPV4, but at least I have it, so thank you. I use the hotspot for work in the field, I guess the question now is am I going have to do step 10 every time I need internet while working. As with others my hotspot was fine until I updated to 13.1.3.

Lost internet connection while writing this back on house internet now. I have been to my carrier several times and they said they are having a lot of calls about hotspot issues on the iphones. So yes Apple please fix this.

I give full credit to these solutions to ska8ter skate. This works for Roku: turn off WiFi on your iOS device. Go to Roku Settings, Then System, Advanced System Settings, choose Network Connection Reset and reset connection.

After updating to iOS 13.2, the issue is resolved. I can now connect to hotspot and get internet access as well on other devices. No issues even after i connect these other devices to another WiFi or hotspot and connect again to iPhone hotspot.

In Windows I can use Connectify Hotspot, which enables me to share the internet connection from the same wireless adapter as I am creating an access point on. As you can read on the technology overview page:

After I saw this link offered by vasishath, I managed to setup a wireless hotspot to share the internet connection from the same single wireless interface device. This wireless device must to use an Atheros driver that is already build with nl80211 support. Next I will show you how.

In wpa_supplicant.conf you must provide the settings of your current wireless network. See man wpa_supplicant for some quick examples. And you probably have more examples in /usr/share/doc/wpa_supplicant/ directory. I used something like:

Let me introduce you to an excellent tool that simplifys everything: create_ap (by oblique)

That is the official repository: _ap

This tool is part of Arch Linux repositories and should be in Ubuntu repositories too!

It is very easy to use and very effective.

To install it in Ubuntu you must first install the dependencies:

(no compilation with make is needed)

Easy, right?Well the rest is even easier... ...If your device is able to be used as a client and a PA at the same time (like atheros wifi chip - edit: some Intel chip too, see second comment bellow) you simply have to connect to your home router with network manager, as you usually do, and than you execute a command line like that:

And... That's it!Incredible and so easy!Now you just have to connect to the repeated network with your android device. You will see in your laptop terminal the handshake negotiated between your laptop and the client:And you can enjoy a nice bathroom session with internet... Everything is done with a single interface and with one simple command. The tool have a lot of options, for more information visit the github repository of oblique (link given previously) and if you can speak Spanish you can check this forum thread: create_ap: La solucin perfecta para transformar tu ordenador en un repetidor universal todo terreno

Here is my project Linux Wifi Hotspot which has both GUI and command-line interface. It can create a virtual wifi hotspot on the same wifi adapter which is connected to the internet. It has additional features such as MAC filter, Change channel/frequency band, view connected devices etc.

As you can see in the comments to this answer ther IS a way to do this. It's documented for FreeBSD (which is not Ubuntu/Linux) here: -to-multiple-ap-with-one-wifi-adapter-under-linux-freebsd (Link from the comment). It does not seem to work exactly the same way on Linux, but it should be similar. Unfortunately I wasn't able to find more detailed information about this topic.

The probably easiest and most common way is using two physical network interfaces. So you may buy another wifi stick or just use another technology to connect further and do just one of them via Wifi. The possibilities are for example:
