@mafu89 As pointed out by @terziyski , you should not have any problems accessing the Fritzbox if your network is set up correctly. I am slightly confused as to why your AX3000 network is so large...

@Lenscof I would look into the possibility of running an ethernet cable from your router's location to another location where you could set up an access point.

I too would like to know more on this. I use AX55 routers which recently added an IoT network along with device isolation options. Perhaps this should be explained by TP-Link in a separate article on...

This would be a nice feature, especially when you have to access more than 1 router.

@Kevin_Z With version 1.2.3, the issue with the orange LED in post #36 above appears to be fixed.

@Kartronics12 Unfortunately, only the main SSID is extended. This issue has been addressed in other posts but never has been fixed.
