This simplest and most obvious approach is simply to turn WiFi off on your 
iMac. This has to force it to use ethernet. If for some reason you find it 
necessary to have both WiFi and Ethernet running at the same time, go to Apple 
Menu > System Preferences > Network. Click on the little Gear icon at the 
bottom of the Services list at he left of the window. Choose Set Service 
Order... from the menu and move ethernet to the top of the list, if it's not 
there already. Click OK and close Network Preferences. It's not possible to 
specify any particular network protocol, at the user level anyway, for any 
particular activity. Your Mac will simply use the first one it finds. If, for 
some reason, it can't use the ethernet connection (cable unplugged, for 
example) it will default to the next available, ie, WiFi. By making sure that 
ethernet is at the top of the list as described above, you are doing all you 
can to "force the issue".

BTW - it's advisable whenever possible to have at least one computer hardwired 
to your Time Capsule, since WiFi is not 100% reliable for a variety of reasons. 
You've obviously had a good run until now, but you are now enjoying the optimal 
configuration.
