Dell Inspiron 17 5755 Whitelisting Question

UPDATE: According to the Inspiron 5755 Specifications document here, you have an M.2 slot for WiFi, not an mPCIe slot.  Additionally, I forgot that having a "5" as the last digit in your model number means your system uses an AMD processor and therefore a non-Intel chipset.  In that case, Intel WiFi cards may not work.  Long ago my wife had a Dell Studio 14z that used an Intel processor but an NVIDIA motherboard chipset, and I tried 3 different Intel WiFi card models, none of which ever worked.  They either weren't detected at a hardware level or Windows couldn't start the device properly even after I tried installing the drivers multiple ways (I'm an IT pro).  I finally gave up and considered that perhaps Intel WiFi wouldn't work on an NVIDIA chipset, so I bought an Dell Wireless card that used a Broadcom chipset instead.  It worked perfectly right away.  You might have to do the same, but since I don't follow Dell Wireless cards, I don't have a specific recommendation to make for you on that front.  But make sure it's M.2 rather than mPCIe!

I have upgraded WiFi cards in many Dell PCs across virtually all of their model lines over a span of more than a decade, and I have never once seen a Dell system that had a WiFi card whitelist like some other vendors do.  If your system has an mPCIe slot rather than the newer M.2/NGFF slot (are you sure about that?), then I would recommend the Intel Wireless-AC 7260HMW.  The "HMW" is what signifies mPCIe since that card is also available in M.2/NGFF format (where it's called the "NGW"), but also make sure you get the Wireless-AC version, since Intel also made a Wireless-N 7260HMW that as the name implies doesn't support 802.11ac.  I have no idea why Intel chose to use the same model number for two different cards with radically different capabilities.

If you DO have an M.2/NGFF slot instead of an mPCIe slot, I would consider either the Intel 8265 or the even newer but harder to find (at least from reputable sources) Intel 9260.

Yeah, I opened it up and checked. It was an m.2 slot, sorry about that. Also, the Wifi card installed is Intel; however, I will go with Amd just in case.

Thanks so much!

AMD doesn't make WiFi cards, but if you already have an Intel card, then maybe that old incompatibility no longer exists, in which case I would recommend the 8265 or 9260, both of which are great cards.  You do NOT want the 9560, which requires certain components to be built into the CPU.
