bonjour

Can no longer access my Linksys WRT1900AC using Bonjour. Can still access my epson printer using Bonjour.

iMac 27 intel 16meg memory

3T storage

Two external drives 4T each.

Mac Pro

iPhone 6+

Window machine

Print.

Trying to avoid re-setting the router.

Any ideas on how to get that device back on my machines?
