I have used an ESP32 wifi module.  The ESP32 is a processor and on that process I use the Arduino libraries which use LWIP under the covers.  I then wrote a simple arduino script that makes the ESP32 be a socket interface via the SPI interface.   I use this for hosting an embedded web server. I was able to get about 1-2Mbps throughput. 

Using the ESP32 is very simple and there are lots of arduino based examples out there.

I've browsed through the list archives a bit and the last thread about
this topic is pretty old (2013-2017), so I'm wondering whether there's
something new on the market (;

For a sort-of an industrial/automation application, I'm looking for a
module which doesn't have to be the cheapest on the planet (obiously
also not the most expensive <; ). I would prefer something which you
could expect to still buy in a few years. The most important aspect for
me is obviously easy integration with lwIP. High throughput is not very
important, at this moment I think this module will be used to serve a
webpage to a single user only. As the user will be pretty close, the
range is also not a huge concern - something which works in the radius
of a few meters will be just fine.

Generally I have almost zero knowledge about such modules, so I don't
even know whether I should be looking for something which works via
PPPoS (like a GSM modem) or maybe something which behaves like a
typical Ethernet combo of MAC+PHY, connected to the microcontroller via

Thanks in advance for all recommendations!
