It seems to be working now.  It was a simple fix of changing the power option to "maximum performance" and restarting my computer.  I will see if this takes care of the problem.  Thank you for your help.

Please give us the router model and the firmware it is running.

Though this sounds more like a PC issue than a router issue.  Can you give us the exact wording of the error message (a screen shot would be best).

N600 WiFi Cable Modem router

Model #C3700

The exact message:  Wi-Fi doesn't have a valid IP Configuration

Did you try connecting over ethernet, and making sure that worked?

Also, what version of windows, and what is the wifi adapter model in the PC?

[crossroads]

windows 10..I have no idea where to find the wifi adapter model in the PC.  And I don't know how to connect over the ethernet

[StephenB]

You connect over ethernet by connecting an ethernet cable between the PC and the router.

Use one of the ways in this link to open the windows device manager: http://www.isunshare.com/windows-10/7-ways-to-access-device-manager-in-windows-10.html  Once that is running, look at the network adapter section.  The wifi adapter will be in there.
