2 macminis (P & G) (and a printer), all connected via Ethernet cable to a Billion router, both running Snow Leopard all working perfectly.
Upgrade G to Yosemite, no other changes.
G can no longer connect to P but all else works perfectly, that is to say that P can still connect to G, both P & G connect to the internet.
G cannot ping P.
Tried the following:- (not in the order shown)
Re-boot router.
Re-boot P & G
Delete all network configurations on G and reconfigure from scratch
Re-configure only ethernet connection
Re-configure Ethernet and WIFI (both give G internet connection)
Summary:
The Ethernet connection from G (and P) to the internet, WORKING
The Ethernet connection from G (and P) to the printer, WORKING
The Ethernet connection from P to G WORKING
The Ethernet connection from G to P NOT WORKING
WIFI from P & G to Internet WORKING
Tks in advance.
