How sure are you that this connection serves only the house that you are staying in?

logging into the router and seeing how many connected devices there are would answer that.

Owner also has the property next door served by the same WiFi from the router. That property is empty this week.

A Hive controller in Port 1 and then split between the 2.4GHz and 5GHz WiFi networks 1 smart TV which is resident and 2 x laptop and 2 x mobile phone which are ours.

Too much to get the sync speed out of the router? If the line speed stays at 40/10 and performance turns dire I'd be looking at the ISP.

Is the speedtest on wired? or wireless? if it's on wireless how many other SSIDs are there visible?

As per first post in topic identical results whether by WiFi or ethernet.

Home router showing with 5-bars on the WiFi scale. Three* other SSIDs, all with 2 or 1 bars on the 5-bar scale with only one of those on the same 2.4GHz channel.

*Further research identified one as a Mercedes-Benz hotspot. The car has now moved away.

Doesn’t necessarily mean that no-one else is using the WiFi.

But there may be equipment in there, security cameras for instance, which may well still be using it.

I’d say, you’re on holiday, go enjoy yourself. Not really your problem. Fret not

It's also possible that the owner is using their holiday let as an offsite backup location for a NAS, which might be locked in a cupboard somewhere. There's simply not enough information to be working with here.

The suggestion to enjoy your holiday is a good one.

Thanks to all who have responded. Obviously no simple or easy fix so let's close things down while I follow the sage advice.
