Nighthawk RAX80 - issue with connection of LG WK7 Google Assist Speaker.

Hi all , just wondering if anyone has connected up a LG-WK7 Google assist speaker with a Netgear RAX80 Router , and had connection issues?

I have setup my new RAX80 with updated Firmware Version V1.0.3.102_1.0.48 , I have then selected Enable Smart Connect in wireless settings , then have tried to connect my LG speaker up to wireless network. ( Previously had a Netgear D7800 , and kept same wireless SSID Name & password , to simplify moving all devices across to new modem) as this was the only wireless product that didnt automatically rejoin the network.

If I untick Enable Smart Connect , and go back to two seperate wireless networks (2.4 & 5 ) LG speaker will join the network on either band I select. But if I tick Enable Smart Control which I gather is the preferred option bu Netgear for best performance, LG speaker disconnects from my wireless network.

Not a big issue , but would like to resolve this problem , as with the summer coming will be using the LG speaker more in BBQ area.

Thanks for any help? David
