Can the HS100 connect to the guest network successfully? Does the main network support turning off the 5GHz?

What's the mode of its wireless standards? E.g. 802.11ax only, 802.11b/g/n mixed, 802.11b/g/n/ax mixed. If it is on 802.11 ax only, try to switch it to 802.11b/g/n mixed or 802.11b/g/n/ax mixed.

As technology evolves, older products, especially those that might be discontinued, face challenges in seamlessly connecting to the latest routers designed with advanced features. While the specifications may indicate backward compatibility, the reality is that older devices may struggle to adapt to the newest technologies.

To ensure a smooth and reliable experience, considering an upgrade to our latest smart home products is recommended. These devices are optimized for compatibility with modern routers and come equipped with enhanced features to meet the demands of today's connected environments.
