OK, so basically I'm adding another computer in my house, but i do not have enough Ethernet ports on my router. From what i have read, the best way to go is to get a switch. My question is, will this slow down my computers internet connection, if it's running through the switch? ( I'm an online gamer, and i download a lot). And also is their a specific brand or type that works best or are they all pretty much the same?
