WIFI Speeds C7800 capping out around 200mbps
Hello, I recently purchased the Nighthawk X4S-AC3200 cable modem router from Amazon.com as an upgrade for my xfinity internet service. I am subscribed to the 1000mbps plan. I understand that wifi...
I have it plugged into a blue 3.0 USB port. I deactivated my intel card and am still only getting around 200, 210 being tops a couple times. It shows 100 percent signal strength. From what I can find I have the latest firmware update installed on the router, even at the 50 percent expectation wouldn't you think I should be seeing faster speeds thru the USB?

do you have another device you can test with other than this laptop? maybe its an issue with the laptop.
- I have a mini PC with the following listed as the WiFi adapter on amazon WIFI: IEEE 802.11a/b/g/n，2.4G+5.8G. I am maxing out at the same speeds on it very close to the router, perhaps 10 feet clear shot, i have also tested in my iPhone 6plue with the same results.
Wifi is tough to test with because so much depends on the devices you're using.
Even the iphone that your testing with the 6 plus, testing showed that it routinely hits MAX speed of 280mbps because it was first generation wireless ac. (this is all from research as I don't have a 6 plus)
I know you think you're wifi isn't doing what it should but you're either testing with older equipment, single antenna solutions, or usb solutions thats reliant on the usb bus.
I've actually used a c7800 for a while and could routinely hit 400-500mbps on a gigabit plan over wireless. But this was using an intel 9260 or Samsung s9.
so I'm not sure what to tell you. You can try factory resetting and starting over. You could also try borrowing someone's laptop/phone that is a newer device to see if even the newer equipment is limited.
The PHY speed of a device is key. Googling iPhone 6 plus, it appears that is 802.11ac and no MIMO. That means the maximum PHY speed (feet from the router) is 433 Mbps (80 Mhz channel). But then due to Wi-Fi overhead, you only expect 50% to 70% of PHY speeds within apps. So, expect 216 Mbps to 303 Mbps. In personal testing I see around 55% of PHY speeds.
With any newer smartphone, you can expect 2x2 MIMO and 802.11ac, which works out to a maximum PHY of 866 Mbps. Then, expect actual speed tests 'around' 476 Mbps (55% of PHY).
And these are maximum speeds. You may be sharing wifi spectrum with others, with neighbors, etc. And then as you put distance between you and the router, expect speeds to drop with increased distance.
