i have 2 questions seeking for help.
1) Can I use wireless adapter as well as wireless network connection together. Or is it a either or situation.
2) The LAN to my laptop is not working although there is connection shown. I believe the LAN configuration has been re-configurated by someone recently trying to change my wireless adapter connection to wireless network connection.
Greatly appreciate any help please.

I don't understand question 1....

For question 2, you need some basic info. Is your network on DHCP? Run an IPCONFIG /ALL and look at the settings. Is the IP there correct? Do you know what the IP should be? IS is set to a static IP or DHCP?
