A while back , I had to substitute my old Linksys router with a fresh one — the honest-to-god one maxed out well below my FIOS connection ’s 15Mbps limit . ( Verizon furnish an ActionTEC router , which solve quite well , but whose admin interface I hate . ) So I purchased aBEFSR41 version 4.1 , which is just a newer version of the same router I already owned .
But after the switch , iPhoto and iTunes sharing no longer worked between my Macs , or with my Apple TV when it arrive . The symptom were bare : I could n’t see a partake in library on my Mac Pro from any other auto in the house , nor could other machines see other shared libraries . It was like the shared service only did n’t exist .
I could work out around the consequence by putting one machine in the so - calledDMZ , but that ’s far from an ideal root . Not only does it open up that one motorcar up to direct memory access from the cyberspace , it also allowed only that one machine to divvy up libraries . I want a solution that allow any Mac to congeal up a share iPhoto or iTunes library that could be see by the other Macs .
I posted for supporter in some of the various on-line forums , but did n’t get anything other than “ yea , me too ! ” So I set about some serious Web digging , and eventually trip onthis threadin the Apple Discussions forum , where I found the solution .
And that solution is this : If you ’ve sire a Linksys router and you ca n’t see shared iPhoto or iTunes program library , open your router’sSecurity page . Down near the bottom , you ’ll see Filter Multicast , and it will be set to Disabled . Click the Enabled radio button , then the Save configurations clitoris . That should be the end of the problem ; as soon as I made this alteration , sharing started working perfectly again between all my Macs and the Apple TV . Note that this fix might cultivate for other troublesome router , but exactly where you ’ll find the setting will diverge greatly from one model to the next .
