The configuration of the access point is specific to the access point.
The PC's are all you really need to worry about. AFAIK there are two
main ways to do the access point/PC side and which one(s) of them are
possible depends on the AP
You can give the AP an ip address in you 192.168.93 range for the wired
side and 192.168.x.x for the wireless side and then have the AP route
between the subnets (or NAT, which is the default on my cisco AP)
Inet |--| 192.168.93.1 192.168.93.2 ------ 192.168.x.x
-----|PC|-----------------------------| AP | - - - - Laptops
|__| ------ (192.168.x.x)
Or, you could put the AP in bridge mode in which case, the laptops would
keep the same ip and IIRC the AP will not even get an ip at all, this
would make the AP the equivalent of a wireless hub.
Inet |--| 192.168.93.1 ------
-----|PC|-----------------------------| AP | - - - - Laptops
|__| ------ (192.168.93.x)

Either way is pretty much unrelated to the PC's themselves and more a
function of the AP.
I think I got the facts straight here, any corrections?
