My new pc I built 2 days ago gets about 6-8 mbps download speeds. It should get 15. This is the 1st pc i built so this is all new to me. A tech from my cable company came out and installed a new modem. When we ran speedtest ookla it had a very good 7 ping w 15mbps down and 2 up. Now he left Im getting half that and my ping is int the 20-30s. So i did some trouble shooting. When I unplug and plug it in again (ether cable) I get 15mbps. 1 time only, then it goes back down. So i hooked up my old pc and it gets the 15 mbps constantly. Its just my new PC. When I First logged into windows 8.1 2 days ago I had no internet access so I called asus and they said I needed to update the LAN from here http://www.asus.com/us/supportonly/Z97-A/HelpDesk_Download/ i did the ist one I saw. the Turbo LAN V1.05.03. I revisited it and saw the 3rd one was intel so i downloaded that too but its still the same slow download speed.
