+--------------------------------------------------------------------------------
+
+2.11 How can I use my wireless Ethernet card with SIMH?
+
+Wireless Ethernet is something of a misnomer - it "works like" Ethernet.
+Wireless cards behave differently than real Ethernet cards in promiscuous mode
+but can be successfully used with existing SIMH code.
+
+The caveat is that the simulated machine cannot run any software which changes
+the simulated MAC address, or the network connection will stop working.  For
+example, DECNET Phase IV (or Phase V in compatibility mode) tries to change the
+MAC of the network card to AA-00-04-xx-xx-xx.  Nor can you preset the wireless
+MAC address to the anticipated target DECNET address using something like SMAC
+to get DECNET to work - DECNET will see the MAC already preset to the required
+DECNET address and generate an invalid media (duplicate address) fault.
+
+Otherwise, TCP/IP, LAT, VMS Clustering, and DECNET Phase V in non-compatibility
+mode work fine.
+
+To get wireless cards to work with SIMH, set the simulated MAC to be the same
+as the MAC of the wireless card.  An example:
+
