This is issues with this laptop network card built on board made by Killer Networks. Try going to their website and download the drivers and install. Mine is intermittent upload speeds of .0# and my GB download of 900+Mbps. They replaced the motherboard and now video is worse. We basically bought a POS machine. If you still have the option of taking it back to where you bought it do so before it's too late. Dell support **bleep** badly. They tend to go through a scripted role on testing that takes hours. Done it to me twice. Never a Dell again.
