Question : How to mix wireless and cabled network and ADSL

Hi,
We have a cabled network, 7 PCs with a Dlink switch, one of the ports are connected to the ADSL Modem.
We have private IP addresses too. Th ADSL Modem has the DHCP feature, so the PCs aquieres an IP automatically.
I need to add a Wireless AP to this network. Does axist any order to connect the devises ?
option 1)
Internet -----> ADSL modem -----> Switch ---- AP

or
option 2)
Ineternet----> ADSL modem ----- AP----Switch

I tried the first option but I cant connect to the AP... the AP gives me IPs from a different range.

Which option do you recomend, and how the AP must be configurated ?

THE ADSL Modem gives me IPs in the range 192.168.1.X

Thanks in advance

Use version 1 and turn the dhcp server off on the AP. Also give it an IP within your Range, and make sure that it isn't one of the IP's that gets provided by your ADSL Modem. If it has a WAN and LAN input, connect it to the LAN using the LAN port and leave the WAN port alone.
