My max internet speeds do not exceed either my wired, or my wireless network speeds, if I'm on the 5Ghz band. However, my internet speed test using ookla over wireless vs wired shows that the wireless is reaching only 50% of what the wired is. I regularly reach 800+ Mbps on the 5Ghz band, and 144 Mbps on the 2.4Ghz band. I am running an Intel Wireless AC 9560 internal NIC. My other question is, with my router the ASUS RT-AC66W supporting speeds up to 1.75 Gbps, and my internal NIC supporting up to 1.73 Gbps, how do I reach those speeds on my internal network. The laptop in question is only 12 ft from the router with an unobstructed line of sight.
