If I understood It well, It emulates a serial port connection over the wifi, and then you need to provide the communication protocol (PPP in that case), but you need a PC as host on one side for acting as a ppp server and for routing...
It's the same as a null modem connection between your amiga and your PC, but without wires... It doesn't connect your amiga to the network (directly).


Doesnt a program like MiamiDx enable the Amiga to be set up with PPP  and work with this adaptor?
I also remember I used MiamiDx with the nullserdevice to emulate a null-modem connection between the Amiga and (Shapeshifter) MacOS8 in order to provide internet to the Mac side. That is internet via nullmodem from the Amiga, but my hope is that it could work the other way as well.

I remember it doing this to, but  inever played around with that function... :(

Miami or Genesis can act as a PPP client, you just need a PPP server on the other end to connect to.  Windows can provide this if set up properly.

I thought that was what the serial-to-wifi device did in this mode, to act as the PPP server and bridge it to the wifi network at the same time

If you are a DIY man, It's very easy to interface an ISA ethernet card to those amiga models.
The same on PCMCIA. PCMCIA is only an extension to ISA bus. I've connected PCMCIA cards to AVR microcontroles with success.
The problem is always the same... drivers...
I wrote my self lots of network drivers for linux and some microcontrollers, but these have well known (and well documented) apis, or no api at all (like microcontrolers). The amiga's problem is to write a sana2 compliant device driver... As far as I know, ofcourse.


If you can attach a PCMCIA card that already has an Amiga driver, would it not be fairly straightforward to adapt the driver to work with this configuration?

Hmmm... It depends on how you connect It. If you are able to mimic the gayle's pcmcia interface, yes, you can use standard drivers.
PCMCIA work similar to Amiga's autoconfig.
There are three memory mappings on the PCMCIA bus. The config space, the memory space (up to 16 Mb) and the I/O space (up to 64k I/O).
On power on or reset, you have to read the required resources from the config space, and assign them. This includes the base address of the pcmcia card (within the 16Mb window fot memory and/or 64Kb for I/O) and the interrupts lines.
As you see, It's not an easy task, and there's a lot of ways of doing It.
The easy way is to interface an ISA card...
Recently, I made a linux driver for an ISA based ethernet chip that can be directly connected to the amiga bus. It's very easy to program and interface. It's the DM9000 from Davicom.
It can be connected to 8, 16 or 32 bit buses.
If you want, I can make a basic design for the amiga.

How about that, it looks like that's the case.  (I didn't read the PDF earlier.)

Pretty handy device.

I was thinking more that the existing drivers could be modified to support your new interface. My Prism-II wireless driver for example is open source, and the code is modular with regard to buses: internally, there are modules for PCMCIA, PCI etc. You would just need to add a small "A500" module; the core wireless chipset driver would stay the same.

In such case, yes, It can be done. But you need to rewrite the driver, you can't use the "plain" driver you use on A600 or  A1200.
As I said, the real problem is to write the driver, not the hardware.

A picture from the product brief.

I think that it could work, but software had to be written. But perhaps that it's not worth it considering the cost of the device, effort to make software and speed it would yield...

But if there was a parallell device? :-)

As discussed earlier in the thread, it apears that the device act as PPP server. So for the Amiga, this should behave like a generic phone modem and should work without any particular software. (apart from the dialup/tcpip program like Miami or similar). It might need a init script to make sure the device is set to operate in the wanted mode though.

A paralell device could probably operate with greater speed, but then you will need the software written for it anyway.

I had some pointers on getting an A600/A1200 online for next to nothing. I know some people would like this serial solution for An A500-type machine, but the load on the CPU and the max. speed of the com port would make it impossibly slow. For A500's and the like, sourcing one of those few network cards that were available would probably be a better choice. For big box machines, the options are greater still.
