I decided to replace the Spark modem as getting frequent dropouts with multiple users. I also had to have an extender for the upper level of the house which was frequently dropping out. I am very pleased with the coverage and don't have to use an extender. We have a 4 bedroom plus study house and getting excellent speeds throughout the whole house. The only downside one of the PCs on the home network with an ASUS PCE-N15 11n Wireless LAN PCI-E Card cannot connect to the router. Asus support suggested disabling wifi 6 on the router but I felt that would negate the advantage of the wifi 6 devices on our home network so will replace with a wifi 6 adapter.

Set up wasn't quite straight forward, as got it all configured and then noticed there was an update to the firmware. After the firmware update the router was not performing so set the router back to default factory settings and reconfigured and all good after that. Have only just set up the router this week so early days but so far happy with the purchase.
