We are having a frustrating problem with our WiFi and I am hoping to get some guidance. Our router is an Asus RT-AC1900 and we have fiber optic ISP through Jaguar Communications.
The WiFi works beautifully as long as the modem is not connected to our PC (Windows 10) desktop. When the modem is connected to this particular desktop, the WiFi shuts down completely. Of note, this set up worked perfectly for 6 months before this problem started with no obvious changes to the set up.
We have connected to another PC laptop and a Microsoft Surface Pro and these devices do not have the same effect; the WiFi continues to work fine with normal speeds when these are connected, suggesting that there is something in this particular desktop screwing things up.
We have spent countless hours on the phone with our ISP, Asus customer service, and even our Sonos guy, but have come up empty. Googling the problem didn't lead to a solution, either.>
I am suspicious for some malware or virus on this desktop, though I've scanned it multiple times with updated scanners and not found anything.
So what could be going on with this desktop that causes the WiFi to fail when the router is connected to the desktop?
Please let me know if you need more information that might provide more clues, and I greatly appreciate any insight!
Thanks,
David
