Unknown devices keep appearing in my network tab
I frequently see unrecognised devices in the network tab of Explorer (Windows version 1909). These include smartphones, printers, TVs and "generic network" devices. They come and go very quickly. I have changed my wifi password a number of times, most recently to one generated by Lastpass that ought to be very hard to guess and which I have not disclosed to anyone else, yet these devices keep coming back. My router (known as a Bbox) is provided by my ISP (Proximus). It has a public hotspot function, but I have disabled this, yet these mysterious devices keep appearing. However when I log into my router and look at the list of connected devices, I only see devices I recognise as my own. In other words these devices only seem to appear in Windows Explorer, but not in the Router itself.
I have started a thread in my ISP's own forum (it's in French), but not got any plausible explanation. How are these devices appearing on my network, and does this indicate that I have a security problem?
