Screen sharing and home sharing makes network drop

Hi. I've upgraded to OS X Mavericks and I am having a weird network issue now. I use home sharing all the time to stream to my Apple TV and I use screensharing so I can connect from downstairs using my ipad or another computer. Every since the upgrade, If I am watching something on the Apple TV and then connect to my Macbook Pro, after a few seconds the Macbook Pro's network connection drops for a few seconds. The Apple TV loses connection to the Macbook Pro completely and my VNC app freezes for about 5-10 seconds. It eventually comes back, but this just happens over and over in a vicious cycle. Any ideas? I've tried running the Mavericks install again and fiddling with screensharing settings and VNC settings on the app, but it just seems like the two don't play well together on Mavericks. I never had any of these issues on Mountain Lion. My Macbook Pro is the late 2011 17 inch model with 16GB RAM. I also have a Belkin thunderbolt dock connected and a monitor connected to that via hdmi to mini display port. The disconnections happen whether I use the ethernet port on the Macbook or on the dock.

I've been having a similar issue since upgrading to Mavericks. I use screen sharing all the time to access my home computer from the road, but now it's hit or miss whether I can log in at all, and when I do, screen sharing eventually drops out after less than an hour.

  • A Sharing and Home Sharing Adventure

    I have a MacPro Desktop that holds a pretty huge iTunes library (35,500+ items). It's the mothership and is connected to my home network via ethernet. I have a Dell Media Center machine (Vista; also ethernet) hooked to the TV and basic home theater system. It's the number one player for Home Sharing. On them, Home Sharing works flawlessly.
    My wife's HP laptop (Vista; wireless connection) and my MacBook Pro on the other hand are a little quirky. If hooked up via ethernet, everything is fine. When using them wirelessly however, Home Sharing (as well as the Shared links in Finder on the MBP) disappear. In fact, I can have iTunes up and running and watch the Home Share appear and disappear as I connect the MBP to the network one way or the other. The most bizarre thing is, it's worked wirelessly before. Nothing changed as far as I know, it just decided one day that it wasn't going to play nicely anymore, or something. After dwelling on this for a bit, I came to the conclusion it had to be the wireless router (Actiontec MI424WR for Verizon FIOS) that was causing the issue. It was the only common denominator.
    Opening the interface, I went to Wireless Settings then Advanced Security Settings. Everything there was innocuously fine. At the bottom of the Advanced screen, however, is a link called Other Advanced Wireless Options. Inside this menu are a number of settings probably better off left alone. The one that struck me was the second one down called "Network". It was set to "Network (Home/Office)". Seemed logical but what were the other options? Of course I checked.
    Whatever selecting "Broadband" actually did (I have yet to find it described in documentation in any detail) it solved ALL of my problems. The floodgates have reopened. From the laptop I can now see the entire mixed network as well as access the iTunes library on the MacPro. What was originally thought by the Apple Care Tech to be related to the size of the library ("I've never heard of one being so large") turned out to be nothing more than a setting in the router's wireless settings menu.
    Now if I can just find out what it did, exactly....

  • My Apple TV is locked on a screen with the home sharing and settings icons in the bottom half of frame and won't let me go back to main menu.

    Apple TV locked on screen with settings and home sharing icons in bottom half and won't let me move back to main menu. Anyone know how to fix it?

    Try the following steps, check whether things are working after each step where appropriate, before trying the next.
    Restart the Apple TV (Settings > General > Restart).
    Restart the Apple TV by removing ALL the cables for 30 seconds.
    Restart your router. (Also try removing it’s power cord for at least 30 seconds)
    Reset the Apple TV (Settings > General > Reset > Reset all settings)
    Restore the Apple TV (Settings > General > Reset > Restore)

  • Can't wake Lion over wifi (or ethernet) using iPad and home sharing.

    I've upgraded to Lion and everything's fine apart from one problem: using my iPad to access home shared iTunes content on my mac no longer works when my mac is asleep.
    That's a change in behaviour from Snow Leopard; I used to be able to sleep my mac and then wake it over wifi using either my iPad or iPhone to access all of my home shared libraries.  The mac screen used to light up for ten seconds and then go dark again, but it served me the files.
    Lion seems to go into a deeper sleep which it can't be woken from.  If I attempt to wake my mac from my iPad within about ten minutes of putting my mac to sleep then home sharing seems to work and lets me use the home share libraries, but if I leave it any longer than that then the mac seems to fall into a coma and can't be woken.  The weird thing is that I still see a "shared library" folder on my iPad, but when I click on it nothing happens.  I think my Time Capsule is listening for wifi access and issuing the magic packet to the mac, but the mac just ain't listening.  
    I'm using a Time Capsule in bridge mode from an ADSL modem and I've accepted a TC firmware update last week and I'm on lion 10.7.3.  I've tried using Ethernet to connect the mac to the TC (and temporarily disabled the wifi connection) but that still doesn't work.  Also, note I'm NOT suffering from the problem that 10.7.3 seems to be giving a few other people - my mac reconnects to my wifi just fine when I wake it up manually.  For the record, This was an upgrade, so there's still a tick in "wake on network" in power settings and home sharing on iTunes is still configured the same as it was before.
    Does anyone have any suggestions about how I can get home sharing to work when my Lion mac is asleep please?
    Jon

    Jonathan:
    The reworked release of the Combo came available the 2-nd or 3-rd of Feb, if you downloaded 10.7.3 complete after that date it will be OK already, no need to instal the Combo. But you can see the exact number of 10.7.3 in System Information/ Software panel: it should be 11D50b.....
    fzahn:
    I understand, I have TC and Extreme also, no need to set anything. And indeed I understand that it may be important for (as it is for me),
    BUT even if it worked after you replaced the kext, I advise strongly not to read in an old kext over a new one, that may give other issues (you observed one already: Airdrop)... I hope you backed up the Lion one... for example such "replacing" was done in one (lousy) tool called TrimEnabler (to install Trim on a non-Apple SSD in the SnowLeopard OS): it replaced the whole kext. I read that there is a new version for Lion that just replaces the text piece that regards the identification for the Apple SSD's.... I do not dare to use such methods.... I advise to read the kext and compare the two (SL and Lion) and perhaps find a way to just replace the one string that is different (be sure it is precisely the same  lenth in caracters)...  BTW: after every update of Lion you have to do it again probably. Keep searching for a better way to solve your problem.
    Did you do the firmware update of the TC and Extreme already?
    BTW: there are two Airport Utilities for Lion: Airport Utility 5.6 and Airport Utility 6, the 5.6 is the "old" visual but in the new one 6 you can not change as many settings; if you want them both, change the name of the one you already have by putting the version number at the end of its name in Utilities, and install the other one, it will be installed additional not over.

  • Solution for Apple TV 2, Xfinity router, Ethernet connection and Home Sharing

    I have read over the past week the problems people have been having configuring their Apple TV and Home Sharing. I was experiencing the same issues as others....until tonight. I finally got it to work with an Ethernet connection. Previously, I was only able to get it to work via wifi and home sharing would drop after awhile.
    1) Xfinity router settings. Like others I was suspicious if the Xfinity router was causing the issues because of the separation between wifi network and Ethernet network. It's not the router problem. I disabled the firewall. Enabled port forwarding. Gave a static IP address to the Apple TV. Added forwarding of ports
       123 TCP
        3689 UDP (all other support says this should be TCP but searched through and found a thread that suggested changing to UDP...this was the key)
        5353 UDP
        80 TCP
        443 TCP
        53 TCP
    DMZ is off
    Device discovery is disabled
    Port triggering is disabled.
    The wifi is setup and functional using DHCP. Lease time is 1 week.
    RESET ROUTER AFTER ENTERING CONFIGURATION.
    2) Mac computer. As of this posting the latest version of iTunes installed. Latest Safari version. All programs updated. Turned on Home Sharing. Turned off firewall. Gave Mac a static IP address. Set Mac for hard drive to never sleep. Set monitor to sleep after 15 minutes. Set date and time to automatically find based upon time zone. ( Apple TV needs to be set to the same time zone as computer and set to manual). Enabled file sharing amongst users on Mac.
    3) Apple TV. Ethernet connection. Configured TCP/IP to static IP address  I configured on router for the Apple TV. Turned on AirPlay. Set date and time to manual and set as the same time zone as the computer with iTunes. Turned on Home Sharing. Using latest version of Apple TV.
    Once the router was reset ( not restored and not just resetting the wifi. A complete router reset), the Apple TV found my iTunes library. It's been running now for over an hour and no drop in the home sharing. Working beautifully. I will be testing in the next couple days allowing the Apple TV to sleep, turning the firewall on the router to a minimal setting to see if it changes anything.
    Just tested the AirPlay from my iPad 2 to the Apple TV while the Apple TV is connected via ethernet connection and it works. At this point it appears that the setup is correct and complete with no errors.
    As a side note, the Ethernet connection between my router and Mac is via commercial devices using the power outlets as the wiring.
    Hope this helps many of you that were/ are struggling to get this to work like I was.

    spma3,
    Appreciate your further message. As you say "it's not fixed", but at least your solution appears to be a viable workaround!
    My Cisco RVS4000 Router will permit me to forward ports for up to 15 applications. Of these, thirteen already have default entries added, although none of these are presently Enabled. For example, here's just 2 lines...
    Application           HTTP        NTP
    External Port          80           123
    Internal Port           80            123
    Protocol                TCP          UDP
    IP Address            No entries at both
    and the Enabled box for both is unchecked. In fact none of these 13 possibilities is Enabled.
    To do what you are advising, I would need to...
    1) Enable the above Port 123 entry, changing it from UDP-->TCP.
    2) Add new entries for 3689 UDP & 5353 UDP... using the two free slots at the end of the table.
    3) Select three of the default entries, and reconfigure them for 80 TCP; 443 TCP; 53 TCP, all as per your guidance. And Enable them.
    Now, my present setup here has...
    1) My PC is wired straight to Port 2 of the Router, and has a Static IP Address set.
    My new ATV2 is hard-wired into the same subnet, albeit thru a series of switches, and again a Static IP is set. My understanding is that hard wiring an ATV automatically disables its WiFi.
    3) My wife's iPad2 is set for DHCP, so it can pick up an IP Address when on the move. It connects into the LAN using one of two WAP4410N Wireless Access Points. Ch-1 & Ch-6, with same SSID and security stuff set up on both. The WAPs in turn are wired in, again with Static IPs set. So depending where she is in the property she can connect with excellent signal strength, reaching the ATV2  by WiFi+LAN.
    On the Router DMZ is OFF, Port Range Triggering has no entries, nothing is Enabled, so is OFF. No idea about Device Discovery!
    Home Sharing is ON for the PC, ATV2 and iPad2, with the same Apple ID/Password set for each. It does work, just not consistently as it should.
    So to fully implement your idea, all I need to do is to enter these details. But I am unclear which IP Address I should put in at each new Single Port Forwarding entry field. Certainly not the iPad2, as its DHCP allocated value will change. Is it the ATV2 or the PC? Not sure, please clarify.
    BTW, I have no plan to deactivate my AVG Firewall on this PC. It is happy to pass all traffic related to iTunes, so cannot see this as a factor. Time zone same on all equipment.
    I tried with just 3689 UDP and 5353 UDP yesterday, and things were definitely better. I used 192.168.20.227, the IP Address for the ATV2.
    Look forward to your answer.

  • Airplay and home sharing does not work with my 2nd gen apple tv

  • Screen sharing and file sharing not working on LAN

    This is not a Mavericks specific problem since it existed before I upgraded to Mavericks.  I have a LAN that consists of 3 MBPs and 1 MacPro.
    Local screen sharing and file sharing works fine on all of these computers except for one MBP.  From this MBP I am able to connect to all of the other computers for screen sharing and file sharing.  But I can't connect to this particular MBP for screen sharing or file sharing from any of the other Macs.
    This MBP shows up in the left hand side column under "Shared" on all the other computers.  But I am unable to make a connection from any computer to the problematic MBP.  I get the message, "There was a problem connecting to the server "xxxxxxxx".  The server may not exist or is unavailable at this time".
    I have tried toggling off and on screen sharing and file sharing with no effect.  One probably pertinent strange thing that I notice is that under the Screen Sharing set up the green button next to "Screen Sharing:On" is green.  But the message under it states:
    "Other users can access your computer's screen
    at vnc://johnmacbookproretina/ or by looking for “John MacBook Pro” in the Finder sidebar."
    The problem is that my computer name is "John MacBook Pro" and the LocalHostName is "JohnMBPr.local".  I believe that at some point in the past the computer name and/or LocalHostName was "johnmacbookproretina".
    Similiarly, under File Sharing I am informed:
    "Other users can access shared folders on this computer, and administrators all volumes, at “afp://johnmacbookproretina” or “smb://johnmacbookproretina”."
    I would appreciate any help I could get to resolve this perplexing issue.  Thanks.
    John

    I've finally been able to solve my own problem.
    File sharing and screen sharing on the problematic MBP was being blocked by firewall rules that had been set up several weeks ago when I had installed a trial version of DoorStop X firewall software.  I had previously trashed the app when the 30 day trial ended.  I did not realize that the software had left a set of firewall rules in the Library/StartupItems folder.  Among other things, the rules were set to deny access to the computer on the ports used for file sharing and screen sharing.  Once I trashed the DoorStopStartup folder in the StartUpItems folder all the connection problems resolved with a computer restart.

  • Remote app and home sharing

    remote app & home sharing worked on my new iPad (3rd gen) but did not work on my iPhone 4. this went on for a week or so but now both of them (remote app and home sharing) work on my iPhone but stopped working on iPad. I tried re installing itunes to 10.6.1.7 (latest version) with no luck. please help because i prefer using my ipad to control my pc

    Be sure that all devices are on the same network.
    If apple tv and remote are on same homeshare you should be able to select and control the apple tv from with in the remote app.
    If apple tv and the itunes are on the same homeshare the apple tv will see the itunes library (and shared photos) in the computer section.
    Additionally if these are all on the same homeshare you should see both the apple tv and the itunes library in the remote app.
    hope that helps.

  • Is anybody else having problems with iOS 7.1 and Home Sharing?

    I have two iPhone 4's - one I recently upgraded to iOS 7.1 and the other running 6.3.1. The phone upgraded to 7.1 will not connect to my (rather large iTunes library) on my Mac Mini (running 10.9.2). The 7.1 phone does see the library - and attempts to connect - but the progress indicator stops at about 50%.
    I've tried de-activating sharing on the Mini and then re-activating. I've tried restoring the 7.1 phone from a back-up. No change.
    Also - now the 6.3 phone will connect to the library - but the playlists have no entries and 99% of the library is missing.
    Before the upgrade - the phone now running 7.1 never had any issues with Home Sharing.
    Anyone else out there having issues with iOS 7.1 and Home Sharing?

    I've had no problems with Facebook on my iPhone 5 but here are a couple of suggestions.
    1. Quit Facebook like I describe then reset the iPhone. Double click the Home button to show the screen with running and recently used apps. Each app icon will have a sample page above it. Flick up on the page (not the app icon) and the page will fly away and the app icon will disappear. This quits that app. Then reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart.
    2. If the first thing doesn't help, quit Facebook again, delete Facebook, and reset the iPad. After the iPad restarts use the App Store app to download Facebook again.

  • AirPlay and Home Sharing are no longer working.

    Recently, Airplay and Home Sharing stopped working completely from my iMac. There just seems to be a miscommunication- AirPlay is showing up, my Apple TV and Airport Extreme are selectable, but then they wont connect. I've been trying to fiddle around with netword settings to try to fix it but no luck. Still works from my iPhone just fine.
    Maybe someone who's Airplay and Home Sharing are working could tell me what their Advanced Network Settings look like?
    Thank you for any help!

    Yes I did all the easy stuff first. I even re-installed Mavericks incase a special file was missing. I've totally reset my AirPort Express several times. It's what's transmitting my WiFi and it's super close to my iMac.
    It's deffinitely a problem with my iMac seeing as it's not working with both my AirPort Express and Apple TV, also can't access Shared movies on my iPad via Home Sharing so yeah... definitely my iMac. All those other things communicate to eachother just fine.

  • Two apple TVs, 4 computers and home sharing

    We have four computers that work well with our Apple TV and home sharing. Is it possible to have a second Apple TV operate on the same network and stream content to a second TV? I seem to recall there was a limit to the number of computers that could be a part of home sharing but I don't recall if there was a limit to Apple TVs
    Thanks.

    You can have up to 5 first gen models connected to each mac, the five limit counts but macs and Apple TVs have a five count each not between them.
    I'm not really sure how many second gen models you can have but it's certainly more than one, I'd imagine at least five and likely more - because it's homeshare not an authorised device.

  • How can I access my music library from a laptop on the road, as if my PC is not active? I tunes is installed on both PC and Home Sharing is enabled on both devices.

    How can I access my music library from a laptop on the road, as if my PC is not active? I tunes is installed on both PC and Home Sharing is enabled on both devices.

    The key constraint for Home Sharing in this context is that both PCs need to be on the same wifi network. So once you get out of range of the wifi network covering your home PC, the laptop is not going to be able to Home Share.
    Have you considered importing your iTunes music to the laptop? Then you could listen to a local copy of the music on the laptop while you're on the road. (You can do the import via home sharing when both computers are on the same wifi network.)

  • Got problems with iOS7 and home sharing

    Got problems with iOS7 and home sharing music. How do you home share music now. I don't have a airplay button either. It all work fine until I updated

    I too am haing the same problem.
    Oh i have an iphone 4 by the way - if this helps.
    I have updated the itunes to 11 point something (latest as of 19th Sept '13) and still not joy.
    My phone sees the network, then when i try to connect to it in the "Sharing" spot in music, it gives me the rotating icon and then i get "Unable to Home Share at this time".
    I had this problem with the ios 6, which was log out of you apple account, and then turn off the phone -this was supposed to clear all the history and old connection details etc.
    Then restart the phone and re-log into itunes account.
    As i say - that worked last time, but this time, i have no idea what is going on.
    I am looking at reverting back to the ios 6, and waiting for ios 7.1 which to be honest - wont be long away with the amount of issues people are having.

  • HT4557 Win 7 with iTunes, iPad3 and Home Sharing Problem

    Hi All
    I have a Windows 7 PC with iTunes installed and Home Sharing turned on. I also have an IOS 6 Ipad (New or 3) with sharing enabled. They are both on the same wireless network.
    After a total uninstall and  fresh instal of iTunes on the PC, all sharing works fine with all albums and artists displayed, and it plays tunes perfectly. Within a couple of days, the iPad only displays a small number of my albums, and they wont play. The 'loudspeaker icon' in 'Music' just skips down the list of songs, playing none.
    I have tried, different versions of iTunes, different pcs (with Win 7), a different router but get the same issue each time.
    Anyone know what is happening. I did only notice this after the compulsory download of IOS 6....
    Regards
    SjH

    I had the exact same problem between my two Windows 7 computers when I updated them to iTunes 10.1 - the shared library would show up on the side in iTunes, but when I attempted to open it, it would say it was loading for a while and then disappear.
    I solved the problem by first turning off Home Sharing on both computers Advanced->Turn Off Home Sharing (act name).
    I then deauthorized the iTunes account associated with my home share on both computers Store->Deauthorize This Computer...
    I then reauthorized both computers Store->Authorize This Computer...
    I then turned Home Sharing back on for both computers Advanced->Turn On Home Sharing
    After following these steps, I am able to use home sharing again.
