Can't open Host FM Files from Client

Recently I switched routers to a Westell 327 Wireless with 4 Ethernet ports. Now I can't open FM Host files from the client. Mac 10.4.7, FM 7.0v3. All files have the suffix .fp7. I checked Network to assure that both computers are the same subnet and router IP. Using DHCP. File Sharing "On", Allow All Users "On". Don't display in open remote file dialog' is not checked. I can mount the hard drive of the Host with the Client. I can attach photo's from the Host to an email. When I try to "Open Remote" under "local host" I do not see the Host (Parent) computer. When I list the Host computer in "favorite Hosts" I don't see files listed under "Available Files". When I list the FM file in "Network File Path" I can open the file. However when the Client computer goes to sleep the connection is lost. Any assistance would be appreciated.
