D54250WYK + 7260HMW

Just added a Dual Band AC-7260 (7260HMW) to my D54250WYK NUC.

Installed, connected the antenna, booted Windows 10 64-bit.

In device manager i got "unknown device", connected it to internet via ethernet and it auto-installed... but only the bluetooth part, no WIFI.

Downloaded the Intel drivers and installed, rebooted, tried again, still no WIFI just bluetooth.

Bluetooth is working as i can see it as a discoverable device.

So why can't i get the WIFI part working?

I've plugged in another WIF dongle just to check that wifi is actually working with another device, and it does work fine with that dongle.

Try this:

1. Download Intel Bluetooth and WiFi driver packages.

2. Uninstall MS Bluetooth driver. Choose to delete files during uninstall.

3. Uninstall Intel WiFi driver package.

4. Disconnect all paths to Internet, including USB WiFi.

5. Reboot.

6. Install Intel Bluetooth package

7. Install Intel WiFi package.

Well, you likely have a defective card. I would check if you can get is replaced via your place of purchase. If you cannot, you can go through Intel Customer Support (ICS) to have it replaced. To do so, first verify it is still under warranty (here: http://www.intel.com/content/www/us/en/support/services/000006303.html?wapkw=warranty+check Determine if Your Product Is Still Under Warranty) and then contact ICS directly. Here is where you can find contact information, by geography:

You can also try using the http://intelsupportchat.force.com/icslivechat/ics_tech_desktop_ww_english_Chat Intel Customer Support Chat Service, but this is offered in English only and is only available during office hours for the Pacific TZ.

Hope this helps,

i bought it from ebay (apparently new) so i'll just return it,

maybe it's fault, maybe it's a fake card.

the AC7260 seems to be quite a rare card to get these days.

what other WIFI card can i use with the D54250WYK ?

You can use literally any card that meets the M.1 Mini-PCIe Connector specification.

This is cards that look like this:

This is NOT cards that look like this:

I can see lots of compatible cards - including the Intel AC3160 and AC7260 - available via Amazon...

the problem appears to be that a lot of these cards on amazon an ebay appear to be fakes or copies (mostly the ones intel branded).

for example, a listing for an AC3160 which should have bluetooth when it was delivered the card had no bluetooth.

the AC3160 is also not suitable for me as it's only 1x1 and only N capable (according to an amazon listing anyway, even though intel say it's AC capable).

too many of the listing are generic and you don't really know what you are buying.

a lot of them are also being shipped from China - which often sets alarm bells ringing.

trying to find reputable places to buy these seems tricky.

Well, this problem is easily solved: don't use eBay (it's all broken, used or fake crap anyway) and either enable Prime on Amazon or only allow Amazon as the vendor (who usually won't stock their own warehouses with used or fake crap).

BTW, the *real* AC 3160 is dual-band Wireless-AC with Bluetooth. It's a little slower, capping out at 433 Mbps, but that's still a pretty good card.

well there's a turn up for the books.

did a wipe and clean install of Windows 10, and low and behold the card now works.

very strange.
