during the course of the day I've managed to restore internet connection
via the ethernet cable but for some reason it still kills the wifi

I've tried everything I can think of
I've connected another pc to the same cable and then everything works fine
so it can't be the ethernet cable
I've connected the problem pc to a different ethernet cable and i still get the issue
I've tried changing the router
this issue actually caused me to replace my router and my motherboard
for new ones because i thought the issue was hardware related
a faulty network adapter or a faulty router

but it seems like that was a waste of time because even with new equipment
the problem persists

the problem is definitely something on my pc
a setting or something....
i'm starting to think this might have something to do with windows 10

Im thinking you need to try using a new NIC card. open up your computer and check your NIC port. Maybe the pins are touching each other causing a conflict to the router to go into protect mode or something? Also find updates for your Nic card driver an that computer since you upgraded to Win10. What kind of router do you have?

Holly crap man, looks like you have a series of pre-existing conditions, just what a doctor wants to hear.

W10? maybe. Did u ever run anything else in that box?

When it kills the WIFI, go into one of the other boxes with WIFI NIC and take a reading on the Signal-to-Noise number just for fun.

not using a separate NIC card in my pc
ethernet goes straight into the motherboard as always
and i don't think the issue is hardware related
because i've replaced the motherboard
so getting the problem on two different motherboards

The driver is up to date

I have a netgear DGN2200

I ran Windows 7 Ultimate
and did the upgrade to Windows 10 Pro
when it was released
and i had no problems like this

then seemingly out of the blue
about a month and a half ago
i started having this nonsense with the wifi
causing me to replace the router for a new one
but while waiting for the replacement router
i was using my old Billion 400 and had the same problem
which led me to think i had a faulty lan adapter on my motherboard
so I sent that back to get replaced as well

so with my pc out of the equation
the other desktop and the laptops and the phones and tablet
could all connect and had no internet problems

then we got the replacement router back
i plugged it in and had no problems

then i got my replacement motherboard back
and as soon as i plugged my pc back into the equation
the problem returned

at first it killed the wifi but the desktops could still connect via ethernet
but then it killed the internet completely
by updating all the drivers for my motherboard i was able to restore the ethernet connection
but it still kills the wifi

everyone i speak to has told me how it's virtually impossible that a pc can interfere with a router's wifi
in this way but that's what's happening

I have a friend who's convinced it's the router and says it DHCP related
he also says that my router might be seeing my pc's ethernet adapter as a mini WAN port and it's trying to bridge
Essentially treating my PC as a router that's connected in a straight line, so to speak. meaning, that it no longer assigns IP addresses to the wi-fi connected PCs, because it's trying to do a pass-through to my "router" - which is not a router.

I dono about any of this because i get the same problem on different routers
it happened on the Netgear which i sent off to be replaced
then it happened on the Billion and again on the brand new replacement Netgear

so I still think something is up with my PC
i'm dreading that my only solution is going to be a format
and then installing my windows 7 again
