Why is there 2 internet connections slots on the back of my computer? Can I use both of them at once?
If you have two network cards, then yes you can. However, don't expect twice the bandwidth. Chances are you're using all you can out of your internet connection already and the second connection isn't likely to help.
So you can have two network connections at once.
are you sure they are the same......one might be an RJ45 connection...(probably got your network cable in it) the other could be an RJ11 ( Modem connection for backup! )
If it is 2 RJ45's check to see if one is a 10/100 and the other a gigabit ....if it is a gigabit make sure you are connected via that one!!
