By "WLAN" do you mean "802.11"?
And, if so, then by "Protocol ID's" do you mean the only protocol IDs I
know of in 802.11, i.e. the protocol ID that appears in an 802.2
LLC+SNAP header that follows the 802.11 header?
If so, then:
1) they're not "WLAN protocol IDs", they're SNAP protocol IDs;
2) there isn't *a* list - the interpretation of the protocol ID
depends on the OUI that precedes the protocol ID;
3) not all of those lists are available.
If the OUI is 00:00:00, then the protocol ID is an Ethernet protocol
type. There isn't a list I know of that includes *all* of them, but
you might look at:
http://www.iana.org/assignments/ethernet-numbers
http://www.cavebear.com/CaveBear/Ethernet/type.html
although note that they just give names for the protocols; you'd have
to search for documentation on the protocol yourself (and many of those
protocols might not be publicly documented). There's also an
"official" list at
http://standards.ieee.org/regauth/ethertype/type-pub.html
but it just gives the organization to which the type field belongs, it
doesn't actually describe the protocol (be careful about inferring the
protocol from the type field - 0x0800 belongs to Xerox, but it's not
the type field for a Xerox protocol, it's the type field for IP.
For other OUIs, the OUI is typically one belonging to a company; some
OUI (vendor) code lists are:
http://www.cavebear.com/CaveBear/Ethernet/vendor.html
http://standards.ieee.org/regauth/oui/oui.txt
but there isn't necessarily a list of protocol IDs for that particular
OUI (I don't know of any).
