Yes you can. And it depends what you mean a secondary card.
But before you have to find out why your wireless does not work. If might happen that you have wrong settings for it or you have turned it off accidentally (some laptops have a switcher for wireless). If you are sure that the wireless adapter was broken you can purchase an usb wireless adapter (secondary card) which might cost you about $20-50 and more (depending on brand and performance).
If you mean a secondary card a lan port then you need a lan cable and non-occupied lan port in your wireless router.
through wireless modem
You need a wireless router capable of working with your wireless card.

If you have a router (connected to internet), and you get a laptop with wireless enabled you do not need anything else. You can connect your laptop to the router and have internet on your laptop.
ok. first if its wireless you should be able to connect by wifi (wireless internet) but if ur not trying to connect via wireless is there an ethernet port on you laptop (it looks like a phone jack but its a little bigger)
Just get a wireless 802.11 adapter for the laptop to connect to the internet.
Yes, you can it's exactly what (wireless) routers were made for.
You have two basic options. 1.You can connect your laptop to your cable, fibre optic, or DSL modem or Ethernet port using an Ethernet cord. 2. You can connect your cable, fibre optic, or DSL modem or Ethernet port to a wireless router using a Ethernet cable. You then connect your laptop using wireless to your wireless router.
Either connect via a wireless network, connect through a 3G network or connect your laptop with an ethernet cable.
