a security aspect you should definitely verify first. If it lacks guest network functionality, opt for a different router.
An additional advantage of having a guest network is that you can restrict the bandwidth so it won’t degrade or influence your main network. This positions the guest network as an ideal candidate for a separate IoT Wi-Fi channel, particularly if you do not plan to use it in a traditional manner. You can utilize the guest network as a dedicated channel for IoT and smart home gadgets. It operates effectively since most smart home devices are only compatible with 2.4GHz networks, and many routers permit you to establish a guest network solely on the 2.4GHz band.
