I don't think this is possible. The only ADSL-related WIC cards the 1750 will support are the WIC-1ADSL, WIC-1SHDSL, WIC-1ADSL-I-DG and the WIC-1ADSL-DG.

Hello,
I don't know if this will work for sure but it looks like you will have to connect your cable modem into your ethernet port and configure the ethernet port to receive a DHCP from your cable provider like this:
router(config-if)#ip address dhcp
Then you'll probably want to create a default route towards your ISP (default gateway):
router(config)#ip route 0.0.0.0 0.0.0.0 e0
Configure your fastethernet interface (LAN):
router(config-if)#ip address 192.168.0.1 255.255.255.0
After that you'll probably want to specify set up DHCP on your router:
router(config)#ip dhcp excluded-address 192.168.0.1 (excludes your f0 ip)
router(config)#ip dhcp-pool INSIDECLIENTS
router(config-dhcp)#network 192.168.0.0 255.255.255.0
router(config-dhcp)#default-router 192.168.0.1
router(config-dhcp)#dns-server 4.2.2.2 (or your ISPs DNS server)
routeR(config)#no ip dhcp conflict logging
Then setup PAT:
routeR(config)#access-list 100 permit ip 192.168.0.0 0.0.0.255 any
router(config)#int e0
router(config-if)#ip nat outside
router(config-if)#ip nat inside source list 100 interface e0 overload
router(config)#int f0
router(config-if)#ip nat inside
I've haven't set this type of configuration up before, but this is where i'd start.
Good luck :)
