Ethernet cable interference

[mciecork]

Router is connected to PC via Ethernet, but was interfering with WiFi connections to devices. When Ethernet cable unplugged from router all WiFi connections worked. Any ideas why?

On the Ethernet connected PC, run and post the results of "ipconfig /all" (without quotes) via the command prompt.

My thought is that there is an IP address conflict that may be resolvable via the PC's network adapter's configurations settings.

Another thought is the port being used on the router: Make and model router and which port is the wired PC connected to?
