The original airport card
The original Apple AirPort card was released on July 21, 1999, as an optional expansion card for Apple's iBook notebooks. It was a rebranded Lucent WaveLAN/Orinoco Gold PC card, housed in a modified design that lacked an integrated antenna. The AirPort card was designed to be user-installable and was offered as an option for almost all of Apple's product line, including PowerBooks, eMacs, iMacs, and Power Macs.
The original AirPort system allowed transfer rates of up to 11 Mbit/s and was commonly used to share internet access and files between multiple computers. It was based on wireless LAN technology, which Apple CEO Steve Jobs discussed with executives from Lucent Technologies in 1998.
It's important to note that the original AirPort and AirPort Extreme cards are not physically compatible. AirPort Extreme cards cannot be installed in older Macs, and original AirPort cards cannot be installed in newer Macs.

Wi-Fi connectivity issues
If you're experiencing Wi-Fi connectivity issues with your MacBook, there are several troubleshooting steps you can take to try and resolve the problem.
First, check that you haven't accidentally turned off your Wi-Fi. Go to the Apple menu in the top-left corner, then click System Settings or System Preferences > Network. If you see a "Turn Wi-Fi On" button, click it and connect to your network. Ensure that you're entering the correct Wi-Fi password, being careful to enter each number, letter, or symbol accurately as these passwords are case-sensitive.
If you're connected to a Wi-Fi network but can't access the internet, restart your MacBook. This will automatically renew the internet address assigned to your device when joining the Wi-Fi network. You can also renew the IP address manually by renewing the DHCP lease. Additionally, make sure that the date and time are set correctly on your MacBook.
If you've installed a VPN or other security software that monitors or interacts with your network connections, try disabling them temporarily to see if they're causing the issue. If your Wi-Fi works with these disabled, enable them one by one to identify the problematic software.
You can also try reconfiguring your Wi-Fi settings. Press Option and click the Wi-Fi icon in the top-right corner, then click "Open Wireless Diagnostics." After running the diagnostics, turn off Wi-Fi and shut down your browsers. Revisit your Wi-Fi settings, turn Wi-Fi back on, and select your network again.
If the issue persists, updating your macOS may help. Ensure your MacBook is connected to power, then go to System Settings or System Preferences and click on Software Update. If an update is available, install it.
In some cases, replacing your MacBook's Airport card might be necessary to improve Wi-Fi connectivity. You can follow online guides to replace the card yourself or seek professional assistance.

AirPort Extreme
The first AirPort Extreme was announced at the MacWorld Expo in San Francisco on January 7, 2003. It featured 802.11g wireless technology for the first time in an AirPort base station. The name "AirPort Extreme" originally referred to any of Apple's AirPort products that implemented the 802.11g Wi-Fi standard, differentiating it from earlier devices that ran the slower 802.11a and b standards. At that time, the gateway part of this lineup was known as the AirPort Extreme Base Station.
In early 2009, with the addition of the faster Draft-N standards, the naming of "Base Station" was dropped, and the product was renamed AirPort Extreme. Several minor upgrades followed with the wireless-N models, mostly to change the antenna and wireless output power. In 2013, a major upgrade changed the physical structure of the device, added 802.11ac support, and added more antennas.
Apple discontinued its wireless routers in 2018 but, as of 2023, continues to provide limited hardware and software support.
