Weird Wifi problem , think its windows 10

[Paul11]

as soon as i switch on my main PC all the other devices in the wifi network go very slow or wont connect

main PC is also very very slow (unusable)

was working fine, even with windows 10

i think a win10 update has buggered something, sound possible?

Have you checked that your PC isn't maxing out your connection (check via Task Manager)?
You checked the IP addresses of all the devices, that there's no clash?

edit update:

i have tried two different routers, both doing the same thing

no IP conflict

nothing running in task manager that would cause it

my main pc runs on an ethernet lead but then other laptops that connect on wifi go very slow or wont connect at all

only solves the problem if i turn my main pc off, then everything else runs fine again

literally as soon as the main PC connects to the router, everything else is slow or wont connect.. .

i think i found it..

a process that is running

just going through them one by one to work out which one it is..
