For the past 10 days when I start up my computer the internet loads, same time period as always, and I find that I am connected to BT. I have to change it over to Plus Net. My adaptor is an Asus 802.11ac and the signal strength is good or excellent.. I see that the radio type is 802.11n. I am on PlusNet fibre optic. As I open up wireless details I have seen ( just now) that I have 2 BT wireless connections nearby and I looked at their properties. It states for them to connect automatically and I have deleted the tick in these boxes. It looks as though I may have solved the problem just on writing this email.
Hi Brainber123, Yes stronger non preferred wifi networks can be a real pain. Another thing you can do is to change the order of the wifi networks - put the PlusNET one at the top of the preference list. Different versions of windows do this in slightly different ways. Look for "manage wireless network".
