Thanks for the advice. I took a look at the network adapters in the control panel and sure enough it had both "Realtek PCIe FE Family Controller" for the Broadband connection (not connected) and "Realtek RTL8188CE Wireless LAN 802.11n PCI-E NIC" for the wireless connection.
So my Toshiba computer is showing the adapter (Realtek) and not the router (Linksys), is that right? Please let me know so I can return to doing my banking and other things online (I stopped when I thought I had a virus).
Thanks delphinium!
