Windows 11 mobile hotspot: sharing your connection

Has your router just given up in the middle of a workday, or are you at a client site in Trois-Rivières with no reliable network? Good news: if your laptop is connected to the internet (by cable or through a cellular stick), Windows 11 can pass that connection along to your other devices. This is what is called the mobile hotspot, and it takes less than two minutes to set up.

A lot of people do not realize that the feature is built right into Windows, with no software to install. Whether you need to rescue a tablet, connect a colleague’s phone or keep a cash register online during an outage, the mobile hotspot is a simple trick that often saves the day. Here is how to turn it on, secure it and use it without any bad surprises.

1. What the mobile hotspot is (and when to use it)

The mobile hotspot turns your Windows 11 computer into a small Wi-Fi router. It takes the internet connection already present on the machine and shares it with other devices: phones, tablets, other laptops or even a network printer. Windows can broadcast that share over Wi-Fi or over Bluetooth, with Wi-Fi being much faster.

In a small business, the feature comes in handy in several concrete situations:

• An outage of your router or of your internet provider, when you still have a cellular connection on one computer.
• An employee working remotely or on the road who has to connect a demonstration tablet quickly.
• A meeting room poorly covered by the main Wi-Fi, until you find a permanent solution.
• An event or a booth where you want to avoid exposing your devices on an untrusted public network.

It is not designed to replace a real business network over the long term, but as a stopgap it is remarkably practical. If what you are really looking for is a stable, well-designed network, our managed IT services cover the design and the protection of your network from end to end.

2. Turning the mobile hotspot on in a few clicks

The procedure is identical on every recent Windows 11 computer. First make sure your machine really is connected to the internet, ideally by Ethernet cable or through a cellular connection, so that the Wi-Fi radio is free for the sharing.

1. Click the Start menu, then Settings (the gear icon).
2. Go to Network & internet, then choose Mobile hotspot.
3. In the Share my Internet connection from menu, select the source (Ethernet, Wi-Fi or cellular).
4. Under Share over, leave Wi-Fi selected for better performance.
5. Turn on the Mobile hotspot switch at the top of the page.

That is all. Windows then displays the network name (the SSID) and the password to use on your other devices. You can also turn the hotspot on even faster by clicking the network icon in the taskbar, then the Mobile hotspot tile. One useful detail: Windows lets you connect up to eight devices at the same time on that share.

3. Customizing and securing your shared network

The name and the password generated by default work fine, but nothing stops you from changing them for something clearer and, above all, stronger. On the same Mobile hotspot page, click Edit under the network properties.

You will then be able to set:

• The network name (SSID): avoid putting your company name or any sensitive information in it, especially in public.
• The password: choose a passphrase of at least twelve characters that is hard to guess.
• The network band: 5 GHz is faster over short distances, 2.4 GHz reaches farther.

Password strength is not a small detail. A poorly protected hotspot can be hijacked by someone nearby, who would then be using your connection (and your data). The Canadian Centre for Cyber Security points out that a strong, unique password remains the first barrier against unauthorized access. Also get into the habit of turning the hotspot off as soon as you no longer need it, to save battery and reduce your exposure.

4. Keeping an eye on data usage

If you are sharing a cellular connection, watch the data. A video call, a large Windows update or a cloud backup can eat through your plan very quickly. Windows 11 helps you limit the damage.

In Settings > Network & internet > Data usage, you can set a monthly limit and get a warning as you approach it. You can also mark the connection as a metered network, which stops Windows from downloading large updates automatically in the background.

A few simple habits to avoid surprises:

• Close the cloud synchronization applications while the cellular hotspot is running.
• Postpone heavy updates to a moment when you will be on a real network.
• Check the data usage screen regularly to spot the hungry devices.

5. Fixing the most common problems

The mobile hotspot works well most of the time, but a few snags come back often. Here is how to settle them quickly.

The switch is greyed out or refuses to turn on

That happens when the Wi-Fi adapter is disabled or when the driver needs an update. Check that Wi-Fi is actually turned on, then update the network driver through Device Manager. A simple restart also fixes plenty of cases.

The devices cannot find the network

Make sure the device that is connecting supports the band you chose. If you are on 5 GHz and the older phone sees nothing, switch back to 2.4 GHz in the hotspot properties.

The connection drops after a few minutes

Windows sometimes turns the hotspot off to save power. In the mobile hotspot settings, disable the option that shuts the sharing down when no device is connected. If the problem persists anyway, it may be an unstable driver, a case where a technician saves you time. Feel free to contact us for quick help in the Mauricie region or elsewhere in Quebec.

Frequently asked questions

Does the mobile hotspot slow my computer down?

Very little. The sharing uses a small share of the network resources, with no noticeable impact on the speed of your computer. Internet speed, on the other hand, is divided among all the connected devices, so the more people there are, the slower each one gets.

Can I share a Wi-Fi connection and stay connected by Wi-Fi at the same time?

Yes, Windows 11 allows it on most recent network adapters. Your computer receives internet from one Wi-Fi network and passes it along through another. If your hardware does not support it, connect the source by Ethernet or by cellular instead.

Is it safe to use the hotspot in public?

Yes, provided you set a strong password and turn the sharing off as soon as you are done. Avoid putting your company name in the SSID and give the password only to people you trust.
