I have a fairly new 3-pack Deco X55 system, v1.6, which I really like. TP-Link just released a new firmware version (1.2.0 Build 20230113 Rel. 54525) with a separate IoT network feature, which is what I (and many others apparently) have been waiting for. It's great that TP-Link is listening!

However, I installed the new firmware, but unfortunately I think that they messed up and didn't really understand what was needed. In particular, I did some simple testing, and when logged on the IoT WiFi SSID, I can see all the devices on my main network: computers, NAS, printers, etc. IMO, the main point of an IoT network is to isolate the IoT devices from the rest of the network, so this new feature is basically useless to me as-is! Does anyone know of a workaround? If not, I'm hoping the the TP-Link engineering team is listening and can fix this soon. Right now I maintain two physically separate router networks, one dedicated for IoT, but it would be great to use the Deco X55 for both functions.

Also, I really want the option of having the IoT network devices see each other, but not devices on the main network. That way, if multiple IoT devices need to talk to each other, they could do so (if I so allow), but the main network is protected. As another example, sometimes during the setup for a new IoT device, the configuring system (phone app or website) needs to be able to talk directly to the IoT device, which isn't usually possible on a guest network.  If TP-Link is listening here, this should be a user-selectable option on the IoT network (as well as on the guest network, imo). I have seen older D-Link routers that had that kind of user-selectable option on their guest network, and it was very useful at times (e.g., when configuring a new IoT device).

Any input or feedback is appreciated. Thanks!
