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.

When the computer is idle is it going into sleep, hibernate or hybrid hibernate?

No matter the brand, all modern laptops use modern standby rather than sleep as we have always been accustomed to.

A wireless adapter drops connection during idle or Modern Standby (S0 Low Power Idle) because Windows aggressively throttles or power-cycles the network card to save battery
Note:the following suggestions will affect battery unless laptop is plugged in.

Device Manager>expand Network Adapters>right click on your wireless adapter>select properties>select power management tab>uncheck "allow computer to turn off this device to save power"

Set Wireless Adapter to Maximum Performance

1. • Open the Control Panel or search for Edit power plan.
   • Click Change advanced power settings.
   • Scroll down and expand Wireless Adapter Settings.
   • Expand Power Saving Mode and set both On battery and Plugged in to Maximum Performance

you could check in the device manager for USB ports and device
then check their properties > power settings
to make sure they are not set to 'power this device down'

you can also check in advanced power settings
control panel > power options > click 'change plan settings'

then in this window click change 'advanced power settings'
in advanced power settings check USB settings
and make sure that is not set to power the USB's down to save power.

best of luck Steve ..

Run `powercfg /sleepstudy` in an admin command prompt and open sleepstudy-report.html (it'll be in the folder you ran the command from) to check whether the drops line up with Modern Standby sessions. Then in Event Viewer open Applications and Services Logs > Microsoft > Windows > WLAN-AutoConfig > Operational, find event 8003 at the time of a drop, and read its Reason line. If the drops line up with standby, set the sleep timeout for when plugged in to Never under Settings > System > Power & battery.

Drafted with AI.

Ok folks well as it happens I was scratching around late last night and an AI site asked me why I need ed to know about airplane mode (I was curious about it as I had run out of stuff to try a fix on my net connection which keeps dropping out and it stated that if I ran a command line with this "reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0" it would disable or stop/force Modern Standby. Those fixes like the power to the card and others I had already tried with zero effect so trying this after backing up the registry I thought was worth taking the risk because nothing else was stopping this laptop from dropping the net connection.
Now this morning I booted and low and behold my net connection was still well "connected". So I am just hoping this will have fixed the wretched problem.
Oh and the site gave me a command as well to undo that command if I ever needed to use the Modern Standby but hey if that lands me back in cuckoo land then why bother? But for anyone interest this is this "reg delete HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /f"
But in any case many thanks to you all for your inputs I do really appreciate the help from you all and this has been why this forum has been so great over the years I have been using it.
