Have to reset my modem

Sorry about the double post guys! Fat fingers here...........My question is: My wireless network uses a Linksys B wireless router. Almost every time I start up my Inspiron 8500 notebook I can't get a wireless signal and have to reset the Linksys by disconnecting and reconnecting the power cable. After that everything works fine. Any ideas on what my problem is?

Thanks in advance.

Do you have the most current firmware installed on the router?

Thank you. I will upgrade the firmware and see if that helps.

Upgraded the firmware but to no avail. I have to re-set my Linksys every time to get my wireless notebook to work.

Is this a cable or DSL connection?

Thanks for the responses. It is Road Runner cable and the card is internal.
