Will the AC-7260NGW work in the DN2820FYKH?

[SMart27]

I'm having issues with dropout and with my ethernet card in my NUC as I keep having drastic speed drop offs. I've updated the BIOS, updated and rolled back, and updated again all the drivers required and am still having issues. Can I use this card in the NUC to provide myself 5G capability hopefully eliminating the suspected speed drop out issues caused by WiFi congestion?

The answer is yes, but you have to be careful to get the correct version. This NGW name has been interchangeably used for both the M.1 and M.2 versions of this card. You want the older M.1 version. The easiest way to do this is with a reference: ​https://www.amazon.com/Wireless-AC-7260NGW-867Mbps-BlueTooth-Version/dp/B00ESBCJSS.

Hope this helps,

@n.scott.pearson​  is the main difference between the M.1 and M.2 the dimensions and the pinouts? I see lots of 7260NGW's but there are two distinctive sizes and pinout configurations. Very few sellers list if it's a M.1 or M.2.

[n_scott_pearson]

Yes, the boards are different sizes (M.2 is thinner and longer), the pinout is very different (pins are higher density on the M.2 versions), the notch(es) are in different places (M.2 version usually has two notches to only one on the M.1) and the size of the antenna connectors is different (M.2 uses smaller connectors).

The M.1 cards are usually referred to as NGFF cards - but even this is incorrectly used in descriptions for some M.2 cards (sigh!).
