Probably the most annoying thing for any computer geek is the lack of proper Wi-Fi connection. Whether we are gamers or casual computer users, having seamless Internet is always a priority. However, we may not be blessed with this all the time, and that’s when we’ll need a M.2 WiFi card to help us out.

M-Cards are backward compatible with current CableCARD devices. In older CableCARD devices that do not support multiple streams, the card appears to be a single stream card. CE companies have long wanted M-Cards for their CableCARD 1.0 host devices in order to compete with devices that use multiple tuners. The ASUS Hyper M.2 x16 Gen 4 Card has four M.2 slots — supporting both PCIe 3.0 and 4.0 — that allow you to expand your system with high-performance SSD storage. While the M.2 standard uses the same 22 millimeter-wide slot for all cards, it’s not necessarily the exact same slot. Since M.2 is designed to be used with so many different kinds of devices, it has some frustratingly similar-looking ports.

What is the M2 Expansion Slot? Definition and Benefits

For the replacement of the mSATA specification standard for the mounted internal expansion boards in the computing machines, in 2013, the M.2 came into the market. It was previously known as Next Generation Form Factor (NGFF).

The Mini PCIe also a good standard to improve the usage of the internal expansion in computer boards. But, to create a better environment regarding performance and space, a standard like M.2 was needed.

It has a different physical structure than the Mini PCIe which means that you cannot install the mSATA drives or other bigger wireless network cards in the M.2 slot. You cannot attach the incompatible device to it thanks to its different key structure.

Ragnarok M Card Slot

M.2 has various versions which allow it to take advantage of USB, Audio, PCIe, Display, SATA and I2C buses. The specifications on the M.2 slot defines which kind of card (single or multiple keyed) can be used with it.

After getting a brief knowledge about M.2 and its working, let’s have a look at the advantages of it.

Benefits of using M.2 WiFi card expansion slot

• The M.2 slot allows having more flexible and faster storage and expansion. For example, by using the M.2 SSD, the data transfer speed can be increased up to 30 GB/S which is almost 5 times higher than the traditional SSD.
• It comes in different sizes like smaller or larger and thinner or thicker, so depending on the space that is available in your system, you can pick up the right length of the slot.
• It helps to take advantages of both the AHCI (Advanced Host Controller Interface) and NVME (Non-Volatile Memory Express) command modes to make an easier interface structure.
• The M.2 expansion slot allows using the feature called as ‘DevSleep.’ This feature reduces the power consumption that the M.2 SSD uses to keep some background service on for quick recovery when the system goes into the sleep mode.

Requirements for using an M.2 WiFi card

Two main conditions need to be fulfilled to use the M.2 WiFi card in your system; space and key. The system should have a separate space for the M.2 slot in which the M.2 networking card will be inserted. The connector you are using also needs to be having the same type of key types as on the M.2 expansion slot.

Who can use this M.2 expansion slot?

If you have a modern computer system, then most probably it should have the M.2 expansion slot. It’s not possible for the advanced laptop users as such machines nowadays come with compact designs that are not suitable for the haphazard expansions. For the desktop PC users, it will be easier to have such expansion slot on your compatible motherboard. Check your motherboard manufacturer site for checking the compatibility.

There you go! We hope this list really helped you pick the right WiFi card for your device. If we missed anything here or if you have any cards that you think can make a list, please let us know!

Most solid-state drives released within the last year or so have been too fast for the bus they're connected to. The 6Gbps SATA III spec was finalized in the days when rotational hard drives still ruled and SSDs were rare, ludicrously expensive, and relatively unreliable.

There are a couple of different standards that have been created to solve this problem, and they both solve it in the same basic way. One, SATA Express, uses the same physical connector as older SATA drives but uses PCI Express lanes rather than the SATA bus to boost storage speeds. The other, which will be more common in space-constrained mini-desktops, all-in-ones, and Ultrabooks, is called M.2 (previously NGFF, for 'Next-Generation Form Factor').

M.2 is interesting not just because it can speed up storage with PCI Express lanes, but because it can use a whole bunch of different buses too; it stands to replace both mSATA and mini PCI Express, two older standards that have been used for SSDs and Wi-Fi cards in laptops for a while now. Intel's new Broadwell CPUs and their chipsets include native support for M.2 and PCI Express boot drivers—neither PCIe-connected storage (hi Apple) nor the M.2 connector itself are new, but beginning with Broadwell systems each of those two things will become much more common.

Let's start with the physical connector and the things that connect to it. There's a lot to unpack, starting with the fact that there's more than one kind of M.2 connector, more than one type of interface that can be used with M.2, and more than one kind of M.2 card.

Getting to know M.2

Pictured at the top of this article are four different M.2 cards. The one on the left is a combo Wi-Fi and Bluetooth card. The next one to the right is a Sandisk SSD that uses the SATA bus. The next one is an Intel SSD that also uses SATA. The one on the right is a Samsung SSD that can use up to four PCI Express lanes.

Pay attention to two things as you compare and contrast these cards. First, the physical connector on each card is different; each card has different cutouts in the bottom and exposes different pins. Second, the cards are of different lengths and widths. All of this is accounted for in the M.2 spec (PDF).

The different connectors signify different M.2 'module keys.' Each key exposes a different set of interfaces to each card—M.2 can connect directly to the PCI Express bus, but different pins can be used to connect to the USB 2.0 and 3.0 buses, SATA III, DisplayPort, and a variety of other less-prevalent storage buses. Cards with one notch at the bottom are keyed for one specific kind of connector. Cards with two notches can be used in two different kinds of connectors.

Above is a picture of two M.2 slots on the motherboard of an HP Stream Mini. The slot on the left uses module key E, and the one on the right uses module key B. The Wi-Fi card is keyed for slots A and E, so it fits in the left slot with no problems. The Intel SSD is keyed for slots B and M, so it fits in the right slot. The Samsung SSD is keyed for slot M, so it won't fit in either of the Stream's slots.

The table above lays out the keys in common use today—there are others, mostly placeholders to be called into service as newer buses and interfaces are introduced.

Note the four- or five-digit numbers paired with each slot. These are actually codes to refer to the physical dimensions of each card; the first two digits specify the width in millimeters and the second two or three digits specify the length. Our Wi-Fi module is 16mm wide and 30mm long, or 1630. Two of our SSDs are 22mm wide and 80mm long, or 2280. The other SSD is 22mm wide and 42mm long, or 2242. All motherboard slots are 22mm in width, even the ones attached to 30mm-wide cards.

All current keys can give cards access to two PCI Express lanes, but otherwise interface compatibility is all over the place—so far, it's been pretty easy to guess what kind of peripheral you're dealing with based on the key it uses. Wi-Fi and WWAN cards tend to use keys A and/or E, since they only need the PCI Express or USB 2.0 buses and only need 30mm in length to fit all their key components. SATA SSDs and SSDs that use two PCI Express lanes tend to use keys B and M to maximize compatibility, since both connectors can deliver both SATA III and two PCIe lanes. The very fastest SSDs tend to be M-keyed since it's the only one that delivers four PCIe lanes.

This is a lot to digest, but it's most of what you need to know to understand M.2. There are some other stipulations around the physical thickness of the cards that you can read about in the documentation, but they aren't as important to our discussion today.

The key system isn't always foolproof—our A- and E-keyed Wi-Fi module will physically fit into the B-keyed SSD slot even though the computer won't recognize it there. M.2 is certainly more confusing than the mPCIe and mSATA specs, but in the end it's more flexible. Components can access many different buses through one small internal connector, and you've got a lot of different physical card sizes to play with instead of being tied to either a 'full-height' or 'half-height' card.

The worst thing about M.2 right now is a general scarcity of components. OEMs buying parts directly from manufacturers probably have more choices, end users buying M.2 cards from Newegg or Amazon will find that they have few options, especially compared to the selection of mSATA and mPCIe components. That will change as M.2 goes mainstream and those older connectors begin to fade. Broadwell is a big step forward in that transition.
