Hello all.

I have a dell inspiron 1545 running xp professional.

I have (recently) a dell 660s desktop running windows7.

I have a netgear n600 router.

the router is wired to the 660s and set to transmit its sid.

I have a data connect usb modem on the 1545 (mobile broadband from verizon)

I want to setup a wifi or home network between the xp, 7, and whatever computers my sisters kids are currently using to allow internet access.

the 7 says only home group running windows 7 are allowed.

tell me want I need, and maybe even where I can find it????

must be able to share folders and or files between all computers and printers (1 printer at this time.)

thank you.
