What those things do is basically wire my computer up using ethernet cables, but using the wiring in the mains.
Both of these products work fine, and I have used them both independently. The speed of each isn't great, but it'll get me by.
I was wondering, is there any way I can get an internet connection from both of these methods simultaneously, possibly making a quicker connection?
And what happens if both the ethernet cable, and the usb wifi card are in at the same time?
