Staying Safe on Public Wi-Fi

Free public Wi-Fi is incredibly convenient, but security can be an issue. Here’s how to minimize the risk, whether you use a laptop, smartphone, or tablet.
Stuck without a data connection on the road? Free public Wi-Fi is one of those little luxuries that can make travelling easier, but you do need to exercise caution in how you use it. Here are some tips on what to look out for when using public Wi-Fi, whether you use a laptop, smartphone or tablet.

Choose your network wisely

Tempted to connect to that elusive “Free Wi-Fi” hotspot? It’s worth doing your homework before selecting any network that’s open or not familiar to you. For example, if you’re in a coffee shop or public library, make sure to verify the name of the network with staff or on signage before connecting.

It’s pretty easy for someone who wants to intercept your data in a man-in-the-middle attack to set up a network called “Free Wi-Fi” or any other variation that includes a nearby venue name, to make you think it’s a legitimate source.

If you are connecting via Windows, make sure to turn off file sharing and mark the Wi-Fi connection as a public network. You can find this option in the Control Panel > Network and Sharing Center > Change Advanced Sharing Settings. Under the Public heading, turn off the file sharing toggle. You may also want to turn on the Windows Firewall when connecting to a public network if it’s not already activated. These settings are also found in Control Panel > Windows Firewall.


On Mac, open up System Preferences and navigate to the Sharing icon. Then, untick the checkbox next to File Sharing. Here’s a full rundown on how to disable sharing and removing public home folder sharing options in OS X.

You can also turn on the firewall within OS X by heading to System Preferences, Security & Privacy and click the Firewall tab.

Use a VPN

Creating a virtual private network (VPN) is one of the best ways to keep your browsing session under wraps. A VPN client encrypts traffic between your device and the VPN server, which means it’s much more difficult for a would-be intruder to sniff your data.


If you don’t already have a VPN set up through your employer or workplace, there are other options available. One free implementation is SecurityKISS which offers ad-free VPN access with data limited to 300MB/day. That’s plenty of scope for checking email, looking at maps and other casual Wi-Fi uses.

CyberGhost is another option that offers a free tier, but also has a paid version that boosts speed.

For detailed instructions, here’s how to set up a VPN on an iOS device and on Android.

There are many other VPN services available, including paid and free options. It’s worth doing your research to work out which is best for your needs, especially if you are a heavy-duty user. helps to protect against session hijacking via browser extensions for Chrome, Opera and Safari, but on the VPN front it also offers a standalone Android app called Secure Wireless that automatically detects unsecured Wi-Fi and activates a VPN where needed.

Check for HTTPS

Like the old saying goes, check for the lock in your browser to make sure it’s secure. One way you can force your browser to use HTTPS is through an extension, such as HTTPS Everywhere. This is available for Chrome, Firefox, Firefox for Android, and Opera.

It’s important to note that HTTPS Everywhere works by activating encryption on all supported parts of the website. As outlined in its FAQ:

“HTTPS Everywhere depends entirely on the security features of the individual web sites that you use; it activates those security features, but it can’t create them if they don’t already exist. If you use a site not supported by HTTPS Everywhere or a site that provides some information in an insecure way, HTTPS Everywhere can’t provide additional protection for your use of that site.”

Patch it up, check your apps

It’s time to start forming some good patching habits. Keep your browser and internet-connected devices up to date with the latest versions, but make sure to do this on a trusted home or work network — not on public Wi-Fi.

There have been instances of travelers being caught off guard when connecting to public or hotel Wi-Fi networks when their device prompts them to update a software package. If accepted by the user, malware was installed on the machine.

Also, if you’re on a mobile device, don’t assume that your apps are automatically secure or using HTTPS. Unless outlined by the app developer, it’s safest to presume that the app is not conducting a secure transaction. In this case, you should use your browser to log on to the service, and check for a HTTPS connection in the status bar.

Enable two-factor authentication

It’s good practice to enable two-factor authentication on services that support it, such as Gmail, Twitter and Facebook. This way, even if someone does manage to sniff out your password when on public Wi-Fi, you have an added layer of protection.

On the topic of passwords, try not to use the same password across multiple services. There are plenty of password managers available to make your life easier — here are six of our favorites.

Forget the network

Once you are all done with your Web browsing, make sure to log off any services you were signed into. Then, tell your device to forget the network. This means that your phone or PC won’t automatically connect again to the network if you’re in range.

In Windows, you can uncheck the “Connect Automatically” checkbox next to the network name before you connect, or head to Control Panel > Network and Sharing Center and click on the network name. Click on “Wireless Properties” and then uncheck “Connect automatically when this network is in range.”


On Mac, head to System Preferences, go to Network, and under the Wi-Fi section click Advanced. Then uncheck “Remember networks this computer has joined.” You can also individually remove networks by selecting the name and pressing the minus button underneath.

In Android, you can do this by entering into your Wi-Fi network list, long press the network name and select “Forget Network.” On iOS, head to Settings, select Wi-Fi networks, click the “i” icon next to the network name and choose “Forget This Network.” As an extra precaution, you should also turn on “Ask To Join Networks” which is also found in the Wi-Fi networks menu.

Finally, be very careful with what you do on public unsecured Wi-Fi. It’s best to save that Internet banking session for when you’re able to connect via cellular data, or on a secure network.

How To Speed Up Your Home Wifi

At the same time, a significant number of business networks supported 802.11a (5 GHz) devices. The first dual band Wi-Fi routers were originally built to support mixed networks having both 802.11a and 802.11b clients.

Starting with 802.11n, Wi-Fi standards began including simultaneous dual band 2.4 GHz / 5 GHz support as a standard feature.

Dual Band Wi-Fi Adapters

Dual-band Wi-Fi network adapters contain both 2.4 GHz and 5 GHz wireless radios similar to dual-band routers. In the early days of Wi-Fi, some laptop Wi-Fi adapters supported both 802.11a and 802.11b/g radios so that a person could connect their computer to business networks during the workday and home networks on nights and weekends. Newer 802.11n and 802.11ac adapters can also be configured to use either band (but not both at the same time).

Dual Band Phones

Similar to dual band wireless network equipment, some cell phones also use two (or more) bands for wireless communications separate from Wi-Fi. Dual band phones were originally created to support 3G GPRS or EDGE data services on either 0.85 GHz, 0.9 GHz or 1.9 GHz radio frequencies. Unlike Wi-Fi devices, phones sometimes support tri band (three) or quad band (four) types of transmission in order to maximize compatibility with different kinds of cellular networks, helpful while roaming or traveling. Cell modems switch between different bands but do not support simultaneous dual band connections.

Benefits of Dual Band Wireless Networking

By supplying separate interfaces for each band, dual band 802.11n and 802.11ac routers provide maximum flexibility in setting up a home network. Some home devices require the legacy compatibility and greater signal reach that 2.4 GHz offers while others may require the additional network bandwidth that 5 GHz offers; dual-band routers provide connections optimized for the needs of each.

Many Wi-Fi home networks suffer from wireless interference due to the prevalence of 2.4 GHz consumer gadgets. The ability to utilize 5 GHz on a dual band router helps avoid these issues.

Dual band routers also incorporate Multiple-In Multiple-Out (MIMO) radio configurations. The combination of multiple radios on one band together with dual-band support together provide much higher performance home networking than what single band routers can offer.

But why 5G products have been choosed for this show?Let’s come to the point.
For IEEE802.11n 2.4G standard, there are total 13 channels. But only channels 1,6,11(or13) are pure. And all other channel will mutually interfere. For example, Channel 3 will interface channel 1~6 and channel 9 will interface 6~13.However, for IEE802.11AC 5.8G standard, there are total 21 Channels. That means there will be more 8 channels for Wi-Fi transmission. For example, there are 13 roads for all vehicles, but now there are 21 roads for all vehicles, but only the new vehicles (5.8G Wi-Fi products) can drive on the 5 new roads and also the old roads. You can imagine there are no traffic jams. That’s 5G.

By the way, do you know many other products also share with 2.4G channels? Such as Bluetooth products (Bluetooth speaker/earphone, etc.), microwave and so on. 2.4G channels will be more and more crowded.

Note: The channels quantity may vary from different country. Here just take China situation as example.
