Alright so I have an internet speed issue. I am suppose to be getting 150Mbps download and 20 Mbps upload. Using speedtest by ookla my upload is 27 Mbps so that's great but my download is only 72-75Mbps. I am using a motorola surf board sb6141 that supports over 300Mbps and then I am using the current Apple Airport Express Basestation. I am also using a wireless card built into my motherboard. This is the Realtek 8821AE 802.11ac PCI-E. Anyone have any idea why I would be getting only half the amount of download I should be getting? Also, would upgrading to an Airport Extreme with the wireless AC help since my Realtek PCI-E card has AC built in? I WANT MY 150Mbps. HELP.
