stumped for an answer

Ok I have a new laptop an ASUS Vivobook 17 X1704VAPBF_X1704VA running 25H2 and after it was booting and running really slowly I updated the BIOS to the latest version and that fixed those issues so I am not thinking my problem is anything related to that.
Now I have had the internet connection dropping out after it is left idling for ay an hour or two and always overnight.
I have been communicating with an AI site and have jumped through that many hoops I have lost count of them.
Have tried disabling the net card a RealTek Semiconductor RTL8851BE WiFi 6 802.11ax PCIe Adapter and to cut a very long story short I now have a TP-Link T2 TAPO Wireless USB Adapter plugged in and and after many other tweaks/hacks to the network setup bypassing the internal card which I also unticked the box for it to be turned off with no effect and am now running a ping through a command prompt to keep the net connection going through the USB adaptor while the laptop is running, and I leave that as is but the connection is still dropped if left for over a couple of hours.
I have also logged into the TP Link site and tried suggested alterations in those settings for example setting the lease time to 86000 but with no effect.
As I do not like keeping he laptop powered on overnight that will mean trying the ping again when booting in the morning - "ping 192.168.0.1 -t"
Now I don't know if it has something to do with Windows version 25H2 because my previous Vivobook ran 24H2 and I never had problems like this nightmare, and for the last six weeks I have also had to jump through many hoops with setting up other stuff and it is getting to the point of thinking to ditching this laptop and going with another brand which frankly I do not want to do but will if I cannot get this network issue fixed before it drives me quite mad. .
So any ideas please I would really appreciate anything at all.
