Wireless router and Internet connection problem?

I have a Linksys wireless router, not a very new model, probably a B series one. Anyway, everytime I'm using my laptop in my room connected to the wireless network I've set up, after a few hours, the Internet will suddenly disconnect. When I try to reconnect it via my laptop, it will always say that it couldn't connect because the security key is wrong. However, I don't change my security keys.



The security type for my wireless network is WPA-Personal, and Encryption type is TKIP. The signal status always consistently ranges from Good to Very Good so poor signal isn't the problem.



Do let me know how I can resolve this problem so that I may enjoy continuous connection to my wireless network, disconnecting only when I want to.



Thank you!Wireless router and Internet connection problem?
