I have a Best Buy floor model HP Envy laptop which is driving me crazy and I've been unable to find this question asked anywhere. I also have a 5 year old HP Pavillion laptop that works fine, as well as a desktop, phones, chromebook, Netflix, etc. that have no internet issues. The problem is one minute the Envy internet speed is working fine and the next minute it virtually locks up. I have tested both laptops next to each other and the old one runs consistent 15 mbps. The new laptop will run 15 mbps one minute and .28 mbps the next. Five minutes later it will run 15 again. I've tried it with Explorer and Firefox with no difference, and it happens wireless or Ethernet connected. HP has looked at it and said it was a software issue, but it has been like this from day one with only HP shipped software on it. The wifi card and the HD have tested out fine and the computer has no error screens or any other problems. It has minimal software on the machine currently and I've run both anti-virus and several malware programs that have found nothing. Does anyone have any ideas what this could be?
