The Modem, if it does WiFi, probably also has NAT/Router/Firewall and
Ethernet. So works with anything with no extra drivers, other than those
normal for networking.
Only USB modems need software installed. No kind of modem for any system
that uses WiFi or Ethernet ever needs SW installed.
You may need to go to a local web page (if so, documented) to enter your
user name & password for the PPoE.
Since the Modem will almost certainly be also a NAT/Router also, only
ordinary ethernet is needed on the Linux box, no PPPoE or PPPoA unless
the Modem is in Bridge mode. Also the configuration web page will let
you be a DHCP client, or disable DHCP server on it and let you use
static 192.168.0.xxx addresses.
The Web configuration page is usually also your default gateway & DNS.
If you leave DHCP enabled all that is automatic.
Any modem I've seen in last 5 years the user guide, manual etc are
PDF so readible without any MS jiggerypokery.
Definately avoid USB connection. Get Ethernet cable working before
entering the mysterious world of WiFi.
About €14 for an Ethernet card, and often even very old PCs have it already.
