There are various reasons why you might want to isolate your work notebook from other devices in your home network:
Many home routers allow connected devices to be isolated, which prevents any direct network communication between selected devices. This section walks you through setting up an isolated WiFi specifically for your work notebook. The goals specifically are:
Note that devices connected via different bands (2.4GHz and 5GHz) are typically not isolated from each other. Likewise, devices connected to your router via cable are not separated from devices connected via WiFi.
Many modern WiFi routers have the capability to generate bridged guest networks that separate devices on the network from each other while keeping things easy to understand. Rather than using your router's built in guest network support for guests, you can instead use it for your work devices. This effectively works the same way as having untrusted guests connecting to your network and should isolate your work device from other devices connected to your home network.
While most routers implement guest networks as described, be aware that your router might implement guest networks differently. Check your router's manual for details.
Note that you will likely not be able to connect to shared resources in your home network such as file servers or shared printers.
A personal VPN (Virtual Private Network) can create an isolated network for a team member's computer that could be used for isolation if the Guest Network idea does not meet your needs. This has the added advantage of being mobile, in that if you take your computer to any network (free Wi-Fi at a coffee shop, hotel network, technical conference with Wi-Fi access for attendees, etc) you can isolate it.
For more information on a personal VPN, check out the Personal VPN page.
Similar to the guest network scenario above, when using a personal VPN you will not be able to access shared resources in your home like a printer.
The instructions are specific to DDWRT, which is a popular custom router firmware. If you don't use DDWRT, you can use the provided steps as a template and consult your router's manual to obtain a similar configuration. However, if your home router does not support setting up an isolated network, consider buying a router that is compatible with DDWRT(ToDo: check which ones support Net Isolation) or a similar custom firmware. If you do, don't forget to expense the router (TBC, check if routers can be expensed). If you need recommendations for DDWRT routers, you can find many buyer guides online:
