Hi @chrisgordon69 . Ethernet devices should be ok. Some users have had trouble with wifi devices connecting to Sagemcom 5G modem. They have used their old wifi router as an access point cabled to Sagemcom.
There were some comments in the past that the Nokia 5G modem was better. TPG might now have reverted to the Nokia modem.
You should ask if there is a cooling off period with the 5G connection. It means if you have problems with 5G you can just return the 5G modem and resume your NBN connection.
Apart from this, how good is your 5G reception? Do you have a 5G mobile phone?
