Network interruptions with both internal and usb wifi adapter.

My desktop computer loses connection regularly and I cannot locate as to why. I have many other devices throughout the house at various locations which maintain a connection fine.

When the connection drops it still displays I am connected, but there is clearly no connectivity.

I've tried toggling between two devices, one an eternal PCI adapter and the other a USB adapter. I get interruptions on both, so my conclusion is there must be a setting causing this.

The desktop has been moved to other locations just in case of interference, and I've tried channel swapping as well.
