MacBook Air WIFI card Upgrade?

Hello,

I have a MacBook Air (2015 early) and the WIFI connection is HORRIBLE. I also have a Dell laptop used exclusively for my job. I can have both on my desk and the Dell connects immediately and reliably to any WIFI connection, yet the MacBook Air has trouble connecting. If I am any reasonable distance from the router (within my own home) the Mac drops connection constantly where the Dell never drops.

My question is - I really like the Air but want to improve the connection - is it possible to replace the existing air card with a different one that will improve performance?

Here is the current card details:

Card Type: AirPort Extreme  (0x14E4, 0x117)

 Firmware Version: Broadcom BCM43xx 1.0 (7.77.106.3 AirPortDriverBrcmNIC-1435.3)

Thank you for any suggestions

Susan

PS - my mac dropped connection 3 times while I was typing this question :-(

Update (12/22/2019)

Thank you all for the information . Here is the information from my WIFI connection

It was suggested by my colleague that I might benefit from a WIFI doggle to bypass the Apple WIFI card, would that be a benefit?

Thank you all again.

Well we can see your connection is over the lower 2.4 GHz band which only give you 145 Mbps compared to my connection which is 5.0 GHz band which offers 300 Mbps. Also note you have the newer 802.11ac board Vs mine which is the older 802.11n.

So clearly you are not connecting to the better throughput band! You'll need to see what your Dell is using to connect and you'll need to identify which AP your system is connecting to. Vs you're Dell.

As far as your friends idea of using a USB dongle most don't offer macOS drivers and the ones that do, are just the older 802.11n units.

If you can get your connection issues worked out with your built-in WiFi it would be better and faster!

Thank Dan, I installed a TPLink range extender at my desk and this appears to be helping. I was able to configure the range extender to connect to the 5.0GHz band and the signal appears much better and when I am connected it performance is good. The only issue I have not is my mac does not easily reconnect when it wakes from sleep - I need to reboot for it to connect properly - but I can live with it.

@CMT_STM - That works too! Now you are relaying from 2.4 GHz to the 5.0 GHz bands. While better your still limited to the throughput of the 2.4 GHz bands. Hopefully you can figure out how to get a direct 5.0 GHz connection altering your systems settings.

MacBook Air Wifi connectivity is not the best among Apple laptops, I have to agree with that, compared to the Pros it’s really sub par. However what you’re experiencing seems to be pointing to a fault of some kind. An upgrade would not be really possible as the only compatible later model is the 2017 Air which has the same specs, but I’d try replacing the Wifi card anyway. Here you can find the replacement board:

MacBook Air (Mid 2013-2017) AirPort/Bluetooth Board

Other than the card, there the antennas in the screen that might get damaged if the Mac was dropped or badly bumped.

Replace a 802.11ac AirPort wireless / Bluetooth 4.0 internal card compatible with the A1465 and A1466 model Mid 2013 to 2017 MacBook Air laptop. Part #661-7465, 653-0020, 653-0023. Görseli

@arbaman - True the MacBook Pro's have a better board and two or three antennas so throughput in the MacBook Air is not as good.

But, that doesn't explain the dropped connections.

Apple hasn’t made anything newer for your system: 802.11ac Wi-Fi (802.11a/b/g/n compatible). It’s a single antenna design supporting both 2.4 & 5.0 GHz band streams.

While your card may have issues I’m thinking you have something else going on here.

Let’s see what network you are connecting to Vs your Dell. It maybe your Mac system is connecting to a 5.0 GHz Access Point (AP) while your Dell is connecting to a 2.4 GHz AP. The 5.0 GHz band allows more throughput but its not effective connecting through some wall types so if your AP is located at a distance or blocked by walls you can encounter issues unlike 2.4 GHz band.

It’s possible the AP your Dell is connecting is physically closer to you and as this AP is not able to support 5.0 GHz the Mac is connecting to a further AP.

It’s even possible both AP’s are able to support 5.0 GHz but for some reason your Mac is connecting to the more distant AP.

I know that’s a bit confusing ;-{ Basically, the connection is not sound vs having a hardware issue within your system.

OK so how do I figure this out?? First know your AP names! Ao if you have two or more routers give them unique names based on where they are in your home Basement, 1st floor 2nd floor etc… Now the tricky part! Your AP’s likely support both bands but you may hookup to the wrong band! So to make this more visible rename the AP’s bands so as an example the 2.4 GHz is called 1stFl_2-4 and the 5.0 is called 1stFl_5 so when you look at your systems WiFi connection info pane you know which you hoped up with as your system can’t tell the difference between the two bands 1st_floor and 1st_floor names!

To compare your signal strength, click on the WiFi icon in your menu while pressing the Option key so you can see the signal info
