Desktop HP 510n wired Laptop Compaq V5101 US Sometimes wired, sometimes wireless Network Printer HP C5180 wired Router Linksys WRT54G -V6 WPA2 Personal, AES On set up/Basic Settings there is a box to input the maximum number of DHCP users. Do I need one, two , three or four. for the above described network. So that I can learn, would appreciate an explanation as to why/how I need the number required. BTW, did not find any reference in search. Forgot to add: The network printer is new and I have tried all three numbers, but seem to get an error message of ip address conflict sometimes, and inability to connect sometimes. Have not been able to relate it to the number of users. Don't know if this is related.
