Ethernet connected devices kicking you offline?

[Brian Agee]

Occasionally I'll see someone say that connecting their reader will kick their computer offline (can't connect to WiFi). This isn't normal, but of course with the computer offline I can't remote in and see exactly what is causing it. It's a setting within the laptop itself that can be disabled.

I believe for most people the solution is a setting in the BIOS, however #4 is another strong candidate to look at if you're having this issue. See attached screenshot of things you can try to fix the issue.
