You may not have much choice if you need to talk to riscos, but
Microsoft's advice is

Stop using SMB1.
/Stop using SMB1/
*STOP USING SMB1!*

Within a home network behind a NAT router, where presumably you trust
all your own devices it shouldn't be an issue, provided you don't allow
VPN access, or anything that could tunnel TCP ports 139 or 445

And now all the Win 10 machines are talking to one
another too.

Wouldn't explain why the Win10 PCs couldn't ping each other by IP addr,
the Computer Browser service (which relies on SMB1) probably explains
why they can now locate each other, but there are newer protocols ...

I spoke too soon. The cabled LAN connected PC does now seem to be able to
talk to the others on Wi-Fi, but not the other way round.

It seems to be to do with the Wi-Fi range extender - I've found several
articles by Googling but they all seem to involve enormous amount of work.
And seem to be referring to a version of Win10 very different to mine. ;-)

In case you'd not realised, this is all well outside my comfort range. My
computing is steeped in the noughties. At the very latest.
