Understanding Wireless Speed Capabilities

Hello everybody!

I'm having a terrible time finding solid information about wireless speeds today. Here's some background regarding my current situation:

Yesterday, I upgraded to AT&T Fiber. The technician took my old modem/router and installed a new modem/router, a Pace 5268AC. The technician had to install it in a hallway closet, exactly where the old modem was located. As he was finishing up, he mentioned that it was silly for me to upgrade to gigabit speeds if I'm not planning on using a wired connection. Not understanding, I immediately began to do speed tests on my different devices.

I did a speed test on the 5 GHz band with my laptop, which has an Intel Dual Band Wireless-AC 7260. I could not achieve speeds higher than 120Mbps down, and the Intel 7260 claims to be capable of achieving speeds of 867Mbps over a 5 GHz band. I also did a speed test on my Samsung Galaxy S6 Edge, and it too received 120Mbps down. I tried two speed tests sites, AT&T and Ookla.

Following the speed tests, I began to play with the settings on my modem/router and wireless Intel adapter. I tried all the tricks I could find online, but nothing worked. This led to more research online. Most articles I found were several years old, but it seemed the general consensus was Wi-Fi can't achieve speeds much higher than 100Mbps. I found this odd, as there are AC routers today that claim to achieve much greater Wi-Fi speeds than that. A co-worker even told me he's receiving 600Mbps down just fine on his Wi-Fi network at home.

So my questions are this: What is the highest capable wireless speed available for a single device? I fully understand a 1Gbps is impossible (at least, that's what I've read online), but what is a more realistic expectation? And to achieve that speed, what type of router should I invest in?

I constantly see routers claiming to achieve 1300Mbps, but is this true? Again, I am not expecting to get 1.3Gbps over my Wi-Fi, but I'm expecting closer to the 867Mbps that my wireless Intel adapter claims.

Please leave the "You should go wired." comments at the door. I'm not routing Ethernet cables from a closet to every bedroom.

Thanks in advance for reading and helping!
 


They are absolutely true!
Routers that claim to achieve 1300Mbps are doing so without question, but its probably something you didn't think of - multiple clients.
That is 10 users all running at 125Mbps which is a realistic wifi speed and certainly acheivable.

1300Mbps on a single client is certainly not possible.

It is pointless to pay for gigabit speed IF you only use wifi, AND you only have a handful of users.

If you don't have enough devices to saturate a gigabit of bandwidth using 125 megabit connections then the tech is correct - you're wasting money.

Thank you for the quick reply. The multiple users makes sense, but I know single devices can achieve more, as my co-worker received much higher speeds on a single device. Even if I reach 400-500Mbps per device, I'd considering keeping the gigabit speed.

Take this router for example:
Linksys WRT 3200 ACM
Speed: 802.11ac: 3x 867 Mbps, 802.11n: 600 Mbps

I understand the 3200 is split up over 1xN and 3xAC, but doesn't that mean I should still see speeds upwards of 867Mbps per device?

I tried it wired on my laptop, and I received around 900Mbps. So I know I'm receiving the speeds from AT&T, but wireless speeds are not as expected.

Keep in mind that my co-worker is receiving the higher speeds, so I know it's a possibility. He receives the full amount for his plan of 600Mbps, so I know I have the ability to achieve at least that with my plan of 1Gbps. My question is, can I go higher since my plan is 1Gbps? And if so, how much higher?
 
I simply don't believe it. Unless he has a MIMO set up of some kind on the client side?

You have 4x4 mimo on the router, allowing multiple connections. (this is why the newer AC routers have so many antennas) They can handle multiple clients concurrently.

I believe it is also possible to have a single client use mimo, effectively allowing it to connect to multiple down streams simultaneously.

Can you provide details on your laptop, his laptop, and his router?

I apologize, he was actually receiving 300Mbps, as his plan is 300Mbps, not 600. Still, that's more than twice my speeds. He has a NETGEAR Nighthawk AC1750, and this speed test was done from a Samsung S5 smartphone.

My laptop is a Lenovo Y50 Touch (59426255) with an Intel Dual Band Wireless-AC 7260.
