WIFI adapter for macbook pro m3 (more 1000Mbps)

This question was raised recently, and research showed that there are NO surviving direct Wi-Fi adapters that work with modern Macs, not at any speed.

Between the requirement for 64-bit capable, and additional squeezing of kernel extensions, they have ALL been crowded out of the Mac market.

There is ONE that takes an Ethernet interface, but offers only 2.4 GHz band, so not really high speed access.

Are you looking to add a second Wi-Fi adapter and presumably via Thunderbolt, or are you looking for the other end of the connection and a Wi-Fi access point or Wi-Fi router that can support what that Mac can provide? Or are you looking forma Ethernet multi-gigabit wired adapter?

MacBook Pro (14-inch, M3, Nov 2023) supports Wi-Fi 6E (802.11ax), which can exceed 1 Gbps under good networking conditions.

Apple hasn’t published specific Wi-Fi specs that MacBook Pro M3 model, but the contemporary MacBook Air M3 can push well past a gigabit under good conditions in 5 GHz and 6 GHz:

You can look up the MCS and NSS values for that Mac and your local channel size and determine the max rates using one of the available MCS rate tables posted around the ‘net.

For the M3 Air, Apple has indicated IEEE 802.11ax using 6 GHz peaks at 2400 Mbps with 160 MHz using 11 (HE) and 2/MIMO, and this again, assuming good RF conditions. These values can drop off quickly with noise or interference, or with distance or walls or such.

If you’re not getting what you expect with the existing Wi-Fi setup, you can view the basic Wi-Fi environment characteristics (using macOS), Option-Click on the Wi-Fi logo 🛜 in the menu bar, and capture some Wi-Fi network data.

If you want us to look at it, post the items shown in the following image including the Security mode and from Channel to NSS inclusive (Security, Channel, Country, RSSI, Noise, Tx Rate, PHY mode, MCS, NSS, green highlight) (without posting the Wi-Fi address, any local HotSpots that might be present, the network name, or the BSSID, all of which are expurgated from the image shown below, red highlight), and we can take a look at the basic network environment.

Adding an additional Wi-Fi interface in your Mac can not fix a situation where the signal is too low, giving you speeds that are also too slow. The transmit power of these unlicensed radios are limited.

When you find the signal strength is too weak, because of distance or intervening construction materials, the typical way of dealing with that is to add an additional access point. You can think of that as a repeater. Best results are obtained by placing it half way between your Router and your Mac.

it can act as an over-the-air repeater, like this:

Network Iinterface......main Router........additional access point(s)

or you can wire a portion of it, which could also support multiples extenders like this:

Each BLUE Ethernet cable can be up to 100 meters long.

What does your Wi-Fi coverage (noise, rssi, etc) look like now?

If your Wi-Fi router or Wi-Fi AP is distant or failing, you’re not going to fix it with a faster adapter, as your embedded adapter is already fast.

If the existing tools aren’t what you’d prefer, you can also use a tool such as the third-party WiFi Explorer app to evaluate the local network environment. (I‘ve been using that app for this purpose for some years.)

The built-in module doesn’t reach well through walls and floors.

Nor will an add-on WiFi adapter.

Particularly for the faster connections, such as Wi-Fi 6E 6 GHz, which are intentionally short-ranged.

You need better Wi-Fi coverage.

what is the issue with the built-in Wi-Fi?

maybe there are ways to fix it. let use know some details.
