hello im new to the forums and i think you guys can help me.
heres my problem. my router is a linksys wrt300n and and my computer i use a linksys wireless receiver. all of a sudden my computer is unable to connect to the network. all other 3 computers in my house (1 also using a linksys wireless receiver) can connect to the network.

so basically i can detect the network but i cannot connect to it. if anyone knows what to do please help me. thanks
