Do any PC's have ac1750?

[calvin-c]

I'm trying to improve file transfer speed between my network drive & my PC. I currently have an N900 router & it's not a whole lot faster than the N300 router I had before so I suspect the bottleneck is in my PC. Wired networking isn't an option in this house. From what I've read about 802.11ac it doesn't provide faster speed in practice because nobody seems to make a multi-stream adapter. Sure it'll provide faster speed as you add more devices but who uses more than one device at a time? So I'm looking for a PC with at least ac1200, preferably ac1450, and better yet ac1750. I prefer built-in wi-fi but if it takes an add-in card I can do that so if there's no PC out there that meets my standards is there an add-in card that does? Thanks.

How about two routers? One as a router the other in bridge mode.

Maybe I'm missing something in your answer? It seems to me that the bottleneck is in the PC's WiFi adapter-how would adding a router fix that? Or maybe I'm wrong about where the bottleneck is? Thanks.

Be very careful about the speeds when you look always look at the 802.11ac speed not the stupid 2.4 + 5g speed. A pc can only use 1 or other other it can not use both at the same time like a router can. It only has 1 radio chip anyway.

The speeds for 802.11ac are multiples of 433 and represent how many parrell streams. Although it is more complex the bottom line is you need 1 antenna per stream. So you get 433,866,1300,1733

The vast majority of equipment only has 2 antenna, you would need something with 4 antenna to get the top speed.

The way the testing sites tend to solve this is they use a router in bridge mode as mentioned in the above post. This lets you use the ethernet port on your PC to connect to the device. Since it is a external box it is much easier to put antenna and get them spaced properly.

Still in real world test the gain you get as you add antenna beyond 2 diminishes greatly. It is transmitting 4 overlapping signals that intentionally interfere with each other. I then hopes to get the signals back at the far end. I am surprised it works as well as it does. Of course when you have 2 or 3 neighbors trying the same thing it degrades even faster.

The maximum rates you should expect even from the top 802.11ac routers are still in the 200-300m range. It also looks like they are getting to technical limitations until they can get 160mhz channel stuff standardized. Unfortunately that means 1 person will use all the available 5g channels so it will interesting to see if it actually runs faster in a crowded location.

I think you've answered my question. Not as I'd hoped, but as I'd feared. I might try the bridge solution although it's not very good for a laptop that I move around the house. I did enough research to understand that I need to check advertised specs *very* carefully, and that I would need multiple antennas at both ends to achieve the claimed speeds-and that I would only achieve them on the 5GHz band. If I understand your answer thought it sounds like nobody makes a PC adapter with multiple antennas. Pity. I suspect that failure contributes greatly to the disenchantment with each 'advance' in WiFi. The fact that equipment with the new standard continues to sell well speaks more to users' hopes than their expectations. Thanks.

I have seen some with 3 but not 4. They are PCI-e for desktop not laptop though. Not sure if they make internal laptop cards with 3 antenna connections or not, then again you would need 3 antenna in the laptop to connect to.
