Listing this under Hacks rather than Newton, because it seems like it would be usable on a lot of older machines:

The module itself is called the Nano WiREACH SMT OB G2. It has some other interesting features, like DHCP, optional external antenna, USB Device and Host, and an Ethernet port (with switching/routing), and FCC type approval.

Giving Wifi To An Apple Newton - Hackaday
{bolding mine}[Jake] has the king of the Newtons – a MessagePad 2100. There’s a hidden port in this machine for a modem card, but Apple never made one. / [Jake] thought it would be possible to build a modern WiFi card for the Newton. He succeeded, opening the door to modern networking apps /
The critical piece of hardware for this build isn’t an ESP8266 or other common WiFi module. Instead, a WiReach module from ConnectOne was used for the built-in PPP server. This allows legacy hardware to use standard AT modem commands to access a WiFi network. It’s a very interesting module; there is a lot of hardware out there that speaks PPP natively, and a module like this could be a drop-in replacement for a modem.
