Soft Wi-Fi, also known as Virtual Wi-Fi, is a software-based solution that enables a device to act as a Wi-Fi access point or hotspot. This technology allows devices, such as laptops or smartphones, to share their internet connection with other devices, such as tablets or other computers, by creating a Wi-Fi network.
Soft Wi-Fi works by utilising the network interface card (NIC) of a device to create a virtual wireless access point. The NIC broadcasts the wireless signal, and devices within range can connect to it. The software running on the device manages the configuration of the virtual access point, including security settings and network name (SSID).
Soft Wi-Fi is a useful technology that provides flexibility, ease of use, and cost-effectiveness. However, organisations must consider the limitations and challenges associated with Soft Wi-Fi before implementing it.
What is Soft WiFi
Soft Wi-Fi is a term commonly used in association with 3G Data Cards or USB Internet Dongles. It refers to the ability to use a software program to turn a laptop into a Wi-Fi hotspot and share internet connectivity with other Wi-Fi devices. Although the 3G USB dongle itself does not have built-in Wi-Fi functionality, it can be used in conjunction with a laptop’s Wi-Fi card to create a Wi-Fi hotspot. It’s important to note that the dongle may or may not come with built-in Wi-Fi hotspot software and that Soft Wi-Fi is different from Hard Wi-Fi, which involves using a dongle with built-in Wi-Fi functionality to create a hotspot.
If your device has built-in Wi-Fi functionality, there is no need to connect it to a laptop in order to create a Wi-Fi hotspot for sharing internet. Instead, you can simply insert the dongle into a USB power source or adapter and connect your Wi-Fi devices directly to it. The number of devices that can be connected will depend on the dongle’s specifications or hardware limitations. This is known as Hard Wi-Fi and allows for direct Wi-Fi connectivity without the need for a laptop or other intermediary device.
The Benefits of Soft WiFi
Soft Wi-Fi offers several benefits, including:
- Convenience: Soft Wi-Fi allows you to share your internet connection with other devices using your laptop’s Wi-Fi card, without the need for additional hardware.
- Cost-effective: Since Soft Wi-Fi does not require a dongle with built-in Wi-Fi functionality, it can be a more affordable option than Hard Wi-Fi.
- Flexibility: Soft Wi-Fi can be used with any laptop that has a Wi-Fi card, regardless of the type of dongle or data card being used.
- Portability: With Soft Wi-Fi, you can create a Wi-Fi hotspot wherever you have your laptop, which is particularly useful when travelling or in areas where there is no Wi-Fi available.
- Control: Soft Wi-Fi allows you to have greater control over who can access your Wi-Fi hotspot, since you can set passwords and security protocols on your laptop.
The Limitations of Soft WiFi
While soft Wi-Fi has some advantages, such as ease of use and flexibility, it also has several limitations:
- Performance: Soft Wi-Fi solutions generally do not provide the same level of performance as dedicated hardware access points. This is because the software-based solution relies on the processing power and network capabilities of the computer or device it is running on, which may not be optimised for Wi-Fi performance.
- Scalability: Soft Wi-Fi solutions are generally not scalable beyond a few users or devices. This is because the device acting as an access point can become overloaded when too many users connect to it, leading to degraded performance and connectivity issues.
- Security: Soft Wi-Fi solutions may not provide the same level of security as dedicated hardware access points. This is because the security of the soft Wi-Fi network depends on the security of the device running the software. If the device is compromised, the soft Wi-Fi network may also be compromised.
- Range: Soft Wi-Fi solutions may have limited range compared to dedicated hardware access points. This is because the device acting as an access point may not have the same power and range capabilities as a dedicated access point.
- Reliability: Soft Wi-Fi solutions may be less reliable than dedicated hardware access points. This is because the software-based solution is dependent on the stability and reliability of the device running the software. If the device crashes or experiences connectivity issues, the soft Wi-Fi network may also be affected.
In summary, soft Wi-Fi solutions may be useful for occasional or temporary Wi-Fi needs, but they are generally not suitable for enterprise-level Wi-Fi networks or environments that require high performance, scalability, security, range, and reliability.

Our Happy Clients
I was struggling to get a decent wifi signal down to the garden office until the Wifi Specialists recommended a Point to Point kit. Now the internet is faster in the office than it is in the house. The guys did a great job installing too, keeping all the cabling very neat and hidden wherever possible. Even sorted out the TV aerial cable while they were doing the P2P cabling! Great service, strongly recommend.
Richard G
Couldn't recommend Indy more highly. They helped us implement an effective corporate wifi solution at very short notice. Communication throughout was excellent and we look forward to working with them again.
Francesca M
Indy and Rakki are first class guys, they did a professional job in record time and I ended up with a better router indoors as well as the Access point outdoors which now covers the whole garden. Definitely recommend the Wifi specialists.
John M
I'm absolute delighted with the service provided by The WiFi Specialist in running an ethernet cable out to my garden office. Indy was extremely helpful in discussion the options available to me, and recommending the right approach, and the work was carried out efficiently and with minimum disruption. I'm thrilled to now have a secure connection, and would definitely recommend The WiFi Specialist to anyone looking to improve connectivity.
Simon M
Excellent, knowledgeable, seamless experience with Indy and team. Not to mention my now perfect wifi!
Sarah K
I had been struggling with my wifi signal around my house for a number of years and the situation only got worse as we moved to remote working. After many attempts to get the issue addressed through the local ISP, I (my wife and kids) decided that I needed a specialist to come in. Indy made the whole process very simple from the initial site visit, design guidance and installation. I had my house refurbished a few years ago so adding new cabling around the house needed knowledge and experience. Indy and Rak did a great job at concealing the cat6 cables and provided a professional finish. I now have full wifi signal all around the house, garden and garage. I would highly recommend The Wi-Fi Specialist. Thank you.
Amarjit K
The IT service from this company was exemplary and resulted in a very good WiFi signal throughout the house. Indy was generous with his time and explained the technology well, without trying to sell equipment that would have been unnecessary for a domestic installation. He is friendly, knowledgeable and very professional. It was a great pleasure to work with him.
