I am using the IP Scanner (and LANscan) software to check my network performance whenever I encounter network problems. I have found that my AppleTV keeps getting multiple IP addresses from my router using DHCP…
What is going on and how can I fix this ?
The most probable cause of your problem is that you are connection over WiFi and the AppleTV is positioned somewhere where WiFi-reception isn’t optimal, and where multiple base stations are giving an equally strong WiFi-signal, which is causing the AppleTV to constantly switch from a connection to the one WiFi-base station to the other and back again.
There is a slight chance that you have this problem when connecting over Ethernet LAN-cable also… in that case you might have some interference or data-loss on the cable which usually isn’t problematic, but still is sub-optimal…
The best and easiest way to fix this is to give the AppleTV a fixed IP-address.
To do so, do this (in tvOS 7.4 – for other versions of tvOS the actual screens may differ) :
unplug the AC-power cable from your AppleTV
restart your router (or unplug it from power for 30 seconds)
plug the AC-power cable back into your AppleTV
turn on your TV (the one that’s connected to your AppleTV)
turn on your AppleTV
goto Settings (the app that has a Sprocket/Gear-icon)
in the Settings-window, click on General
in the General-window, click on Network
in the Network-window, click on WiFi (or Ethernet if you use it)
in the WiFi-window (or Ethernet-window), click on Configure IP
in the ConfigureIP-window, make a photo of all settings or write them down (because this exact info is what you are going to enter manually), then click on Manual
in the IP-configuration window, roll the dials until the IP is set, then click OK
in the Subnetmask-configuration window, roll the dials until the Subnetmask is set, then click OK
in the Router-configuration window, roll the dials until the Router IP is set, then click OK
in the DNS-configuration window, roll the dials until the DNS is set (or use 008.008.008.008), then click OK
then wait for the setting so be accepted while the wheel spins
then exit, exit, exit until you’re back on the Home screen
That’s it !
Note : if you want to be completely sure that your AppleTV has accepted all settings, you can unplug and replug your AppleTV from power, but that is not as important as it used to be in older versions of tvOS – and you need to check afterwards in Settings to be completely sure
Lately I have had a bad and unstable internet connection. I have a Mac and it has been working fine for years. My internet provider is Vodafone-Ziggo.
I tried to find out what was wrong using the AirPortUtility.app on my Mac, and I found something strange : when selecting my wireless WiFi-network, my internet connection is presumed working, but when selecting my wired LAN-network, I get an error message saying there is no internet connection.
If it would have been the other way around, I could think of an explanation… but having wireless internet connection from my router and not LAN-internet just doesn’t make sense…
I’ve tried numerous resets of the Ziggo-modem, of my TimeCapsule and of my Mac. Nothing helps.
Do you have any suggestions on fixing this ?
Even though you’ve tried most of the available options already, there is one other thing I would suggest to try :
make sure the UTP/Ethernet/LAN-cable is correctly connected into both your Mac and the ‘local network device’ (be it a TimeCapsule, a router, a modem, a network-switch or a wall-socket)
then, on your Mac : click on the Apple-icon (top-left on your Mac’s desktop screen)
in the pulldown menu, click on “System Preferences”
in the window that opens (“System Preferences”), click on “Network”
in the window that opens (“Network”), click on “Ethernet” in the list on the left
in the info that appears on the right, check if it says “Status : Connected”
if it doesn’t, your UTP/Ethernet/LAN-cable isn’t connected properly, so check all network-cables again until it says “Status : Connected”
then, click the Advanced-button
in the window that opens, click on the DNS-tab
in the info that opens, at “DNS Servers:” make sure that you have at least included one of the following DNS Servers : 126.96.36.199 (Google), 188.8.131.52 (Google), 184.108.40.206 (OpenDNS) and/or 220.127.116.11 (OpenDNS)
if none of those DNS Servers are listed yet, add them by clicking on the +/Plus-button bottom-left
then click on the Proxies-tab (of the elongated TCP/IP-button)
in the info that opens, make sure to remove the check-mark at both “Web Proxy (HTTP)” and “Secure Web Proxy (HTTPS)”
in case both were already switched OFF, I would suggest to switch both of them to ON
then leave the rest as is, and click on the OK-button
in the previous window that appears, click the “Apply”
now check the AirPortUtility.app again, and you should see that the internet connection is back up for both the wireless and wired/LAN connection
