If you're using one time passwords (printing out a password on each coffee receipt, where each password is only good once) then HTTPS isn't required, but otherwise HTTPS is definitely required. Personally I wouldn't bother with WEP since it's so easily cracked. >>- dhcp server >>- block every ip of mynetwork (to hotsport subnet) except default >>gateway destination. >>- the same SSID on ap1, ap2, ap3 (are linksys) >> >> >fine, but might get confusing when troubleshooting and testing link strength. > > Same SSID is good since it allows roaming between access points. >>- the same channel on ap1, ap2, ap3 >> >that might cause problems, not sure. > > This will *definitely* cause a problem. Put the APs on 2, 6 and 11 -- This will allow most wireless NICs to automatically determine which AP has the best signal without worrying about overlap or signals canceling each other out. Having two or more APs on the same channel will, at best, cause massive packet loss. More likely it will render the entire network unusable, especially if somebody shows up with a stronger-then-average antenna and transmitter and two or more APs start thinking they're both receiving communication from one client. -- Usenet is like a herd of performing elephants with diarrhea -- massive, difficult to redirect, awe-inspiring, entertaining, and a source of mind-boggling amounts of shit when you least expect it. |
