I am also trying to switch the linked Hopper on one Joey. My Setup is two Hoppers and one Joey. When I upgraded my setup last week the installer linked to the wrong Hopper. I can unlink the Joey to the living room Hopper, but it will not link to the Hopper down stairs. I tried rebooting both Hoppers and the Joey and still cannot connect to the downstairs Hopper.
Is there a setting on the Hopper that needs to be changed to allow me to link to it? When I go to the setting on the Joey I see both Hoppers and when I select the one I want I get the press select to link. After I press select nothing happens. But if I do the same process on the living room Hopper (the one I do not want to link) it links with no problems.
Any help would be greatly appreciated.
