Bought Intel Wireless AC 9260
installs okay. but asks to be turned on.
There is no hardware way to turn it on.
A most excellent question. AC 9260 installed, software installs no glitches. But the card will not turn on. in settings I am unable to turn it on. Not related to airplane mode which I can toggle on and off from the keyboard.
I saw a mention of AC 9260 being able to work if I were to clear tape pins 56 and 57. The writers description of the pins did not match the AC 9260 on either side. So that also did not work. I presume the AC 9260 NFGG has added a feature for a hardware switch to enable or disable that the Acer S-7 392 does not support. That's what I mean be "the card will not turn on" in settings.
Thank you for taking a peak. I know I shouldn't be trying to upgrade such an old notebook, but I still like it.
There is absolutely nothing like that in/on this card or its drivers.
Wait a minute, something is not right here... This is a laptop with a 4th gen processor (i7-4500U/i5-4250U or something similar), right? If so, M.2 connectors did not exist back then; only the mini-PCIe (a.k.a. M.1) connectors existed. There is no version of the Dual Band Wireless-AC 9260 that comes in the M.2 configuration; it only came in the M.2 configuration. This means that the best possible solution for this laptop is the Dual Band Wireless-AC 7260.HMW (here: https://www.amazon.com/Intel-7260-HMWG-R-Wireless-AC-Network-adapter/dp/B00MV3N7UO).
Acer Aspire S-7 392 is 7th gen Intel I-7.
I believe you are right that the 9260 just will not work.
I will order a Intel Wireless AC 7260NGW NGFF. Hope that will work.
The link goes to a mini-PCIe and that won't fit the Acer MB.
Ok, now you are confusing me. Which is it? The link you provided is for the M.2 version, the Dual Band Wireless-AC 7260.NGW, not the Dual Band Wireless-AC 7260.HMW that my link pointed to.
For certain, and I am looking at it, the card is the Dual Band Wireless-H 7260.NGW NGFF. I am learning that the form is M.2 but I know it as NGFF.
That is what I'm replacing.
The Dual Band Wireless-AC 9260 M.2 card supports 1733Mb/s Wireless-AC and Bluetooth 5.1 that I bought and installed had the "turn on the wifi" error message. Alas I can't turn in on in settings whatsoever. It gets installed but never looks for a wifi network. Windows thinks its turned off via hardware. If the error message is even indicative of the issue.
So I'm dialing it back to try for the:
The Dual Band Wireless-AC 7260.NGW M.2 card supports 867Mb/s Wireless-AC and Bluetooth 4.0.
Which I have on order.
But this is essentially replacing the original card, not upgrading it. I am of the opinion that you got a bad 9260 card. You should return it for replacement.
