Wifi Hotspot

Most modern smartphones have a hotspot mode, but cellular modems and Wi-Fi hotspots have historically been your best and most flexible option if you have a lot of devices that need web access when outdoors or in other non-connected areas.

Hotspots can connect more than just laptops to the web. They also work with tablets, cameras, and pretty much any other Wi-Fi-enabled gadgets. They support more devices (10 to 30) at one time than your phone's hotspot mode (5 to 10), don't drain your phone's battery, and can hook up with the better antennas in your phone. Your company might even cover its service plan.

When we tested Inseego's MiFi X PRO 5G hotspot in an area with a strong T-Mobile 5G signal, we got blazing-fast download and upload speeds of around 600Mbps and 22Mbps, respectively. Impressively, that's faster than many people's home internet connection. Otherwise, its 2.4-inch touch display makes it simple to configure options and a built-in Ethernet port expands its versatility.

This is the hotspot to buy if you're in an area with good T-Mobile 5G connectivity and need top-notch performance. It's not the most affordable hotspot, but its speed and easy operability help justify its premium price.

If you don't want to commit to a carrier or frequently need to change SIM cards for travel, this hotspot is ideal. You pay a bit more for the ability to switch providers at will, however, so you can save money by choosing a carrier-specific model.

Along with the three major carriers, you can get hotspots from Boost (AT&T/T-Mobile), Cricket (AT&T), H2O (AT&T), Karma (T-Mobile), Metro (T-Mobile), Net10 (Verizon), and Simple Mobile (T-Mobile), along with other minor players.

Hotspot plans change all the time. On AT&T and Verizon, your best bet is to add a hotspot to your existing carrier's phone plan as a separate line. That gets you the most data for your dollar. If you add a hotspot onto an "unlimited" phone plan, you get up to 150GB of high-speed data with Verizon, up to 50GB of data with AT&T, and up to 40GB with T-Mobile. After that, the carriers deprioritize your data or throttle it unpredictably depending on local network traffic.

The median US home broadband subscriber uses more than 587GB of data per month, mostly because of video streaming services such as Hulu and Netflix. All of those Zoom calls are also likely to eat up a data cap quickly. If your needs don't involve video or music streaming, a wireless hotspot might be a viable alternative for your home.

However, there is such a thing as wireless home internet, and it's different from hotspots. It relies on exterior antennas and larger, less portable routers that stay in one location. Recent wireless internet plans are more likely to have unlimited data than hotspot plans. AT&T, T-Mobile, and Verizon all sell wireless home internet via 5G in various parts of the country, along with a wide range of smaller, local wireless internet service providers (WISPs).

The three big carriers have been frantically upgrading their networks recently, and in many cases, network capabilities have now outstripped the quality of older hotspots running on them. That means recent phones will get better speeds than older hotspots do.

Many high-quality hotspots have TS9 external antenna ports to help you improve your signal using inexpensive antennas you can purchase online. TS9 is standard, and these antennas cost much less than cellular signal boosters. Unfortunately, 5G hotspots that support mmWave generally don't have external antenna ports.

Ensure your hotspot supports 5GHz Wi-Fi, which is typically faster and less congested than 2.4GHz Wi-Fi. Some hotspots support guest networks and access controls, such as MAC filtering and time-based access controls. Those features are on pretty much all dedicated routers nowadays, but you can't take them for granted on mobile hotspots.

You can use hotspots with big batteries as power banks to charge your phone, or hotspots with microSD card slots as tiny servers to share media over Wi-Fi. That said, we've never found a real use for that media server functionality.

If you decide to make the jump, hotspots and cellular modems aren't the only options. Smartphones have a Wi-Fi hotspot mode, and if you have a 5G phone, you might get better performance in that mode than you would with a 4G hotspot. That said, phones support fewer devices at once, have fewer network management features, and can run out of battery quite quickly.

One of the only good unlocked hotspots with international bands available in the US is the Netgear M6, but it's quite expensive. If you plan to buy a local SIM to take advantage of much lower local data rates, you may want to buy a cheap Android phone abroad and tether from it.

Does the 23 model have a wifi hotspot to connect my phone and other devices to the vehicle's LTE signal? I found it in the 2021 model but the menu steps are different fromt what's available in mine and I don't see anything in the 23 manual

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.

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.

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.

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.

(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:

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:

Once I noticed that Ubuntu Linux is capable of managing two wifi devices at once without being complicated. I did not test this in ways of sharing the internet connection etc, but it should be possible. The way how complicated it will be is probably depending of the type of connections you use. On Linux you probably do not need and kind of special software. It should be possible to share connections without the need for any special tools. Unfortunately I cannot try it at this time.

I recommend you try Wifi to Wifi if you have another wifi stick anyway and otherwise LAN or Bluetooth (which is built-in in most notebooks). 3G/LTE sharing is a bit bad because of providers dataplans and so on.
