Windows at a crawl when I lost my ReadyNAS

[Crabhappy]

I can't find where to start a new thread. So Please excuse me if I am in the wrong area. My problem is that my computer running Win 7 was working just fine. All of a sudden I lost connection to my ReadyNAS duo. It does no longer show up on my network. Now my computer is running slow. I don't know if this is related. I do know that the NAS has an IP that is different to the router. It is an Xfinity modem/router combo and I had them reboot my modem. When I did that the NAS is no longer in my network group. I did notice that my router can see the NAS but the IP is different than the NAS. I don't know how to change this modem to the IP address of the NAS or I can't change the NAS to match the router IP for the NAS. Any suggestions?
