Wireless card is a: Intel Dual Band Wireless-AC 7260 (internal PCI-e)

Rate in windows 866.7Mbps

Yes the machine has a SSD at least 500MB/s

I have tried split and combined SSID, also tried turning off 2.4 and using just 5 and made sure the card only prefers 5Ghz.

The speeds are being measured by the windows dialog and i did try speed measurments using iperf under a live linux.

Just to note though, it all works fine over wired... so it rules out drive speed.. machine bogging down.. etc.. it is only the wireless that has the issue.

I have never tried internal network transfer speeds on a HH5B.

I had issues with the 5Ghz dropping below 10Mbps, I struggled to even max out my 55Mbps connection.

Is anybody able to confirm their results?

I have a BT Smart Hub and can do 400Mbps over wireless with a wireless card at the same transmit speed.

Realised this is related to plusnet one hub, this is a rebranded HH5A. I can get 400Mbps over this using a macbook air 2015, wireless AC. I am tipping the issue is the wireless card in the laptop. Intel cards do not have a great track record. Typically they can be changed and / or upgraded, but not easily.

Say you have a DELL laptop, DELL will have a bios whitelist which says the machine will only boot if it detects a small number of wifi cards, so if you go and buy a top of the line wireless AC card and put it into your laptop, chances are the machine will not boot. The machine will only accept probably 4ish wireless cards.. This is done because inside the laptop are antennas, and the antennas are designed for certain cards, DELL is able to verify if you use these cards with the antennas inside the laptop - you will not exceed any legal limits. DELL does not try every single wireless card in the world and verify that the legal limits on output power are not exceeded if used with their antenna arrangement, instead DELL, HP, ASUS etc whitelists in the bios the cards which are known to be ok & are tested (usually a small number) and only allows these to be used internally.

Well I have had a look at what card the macbook air that you tested with, it has a Broadcom BCM4360 based card, capable of upto 867Mbps, so same theoretical speed.

I can't actually find any other card that will fit this machine.. the intel is the highest i can find..

I've had some of these Intel Windows cards, one is in my work laptop, and gives me a throughput of 30Mbps despite being wireless AC. I would have to check the model number but some cards just suck.

Have you got an iPhone 6 or 6s or a modern iPad to hand?

If so connect to the hub using 5ghz and download an app called wifi-sweetspots. What speed are you getting. As an example I am getting around 350 to 400Mbps through 2 walls using 5Ghz and iPhone 6s.

Totally untrue Re. white listing Wireless Cards.

What's the real reason?

This was what HP themselves explained to me when I enquired with the on site engineer why I was unable to use my own wireless card.

Could be total rubbish for sure.

I have no other 5Ghz devices to test this with, so I can only go by this Intel card.

I can't find any other cards that arnt intel, I don't want to use a USB one as I know that would be limited.

Starting to think I will just have to accept this low end speed and just use wired if I want something faster.

Lenovo (formerly IBM) whitelist cards. I think HP might do this, but DELL never have in my experience. Intel WiFi cards are often much more stable than Dell's generic brand (early ones were broadcom, later seem realtek). The cheaper laptops often have only one antenna, despite the higher spec card.

This might be of use on a Windows laptop, now that inssider is no longer free:
