Windows wireless network log on error

[graybob22]

Hello,I have a Linksys wireless-N Router (WRT160N)and I can access it with my laptop, phone, and IPad. Every time I try to connect with my PC, it pops up a "Network Authentication Please enter user credentials."
I have have Windows 7 operating system.
I have been using this router with this PC for a couple of years without this error.
Please help.
Thanks,
