Nov 7, 2015 12:07 PM in response to Richgradby Winston Churchill,Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.
The following article(s) may help you.

Nov 7, 2015 12:29 PM in response to Winston Churchillby Richgrad,thanks for your detailed response. netstumbler says no network adapter found on my pc. my apple tv has been working fine until now. there are no appliances on or near my apple tv. but every time I play a movie on my television streamed via apple tv from my itunes on my pc, it literally kills my router. it's completely dead. no lights, not even power lights but the power switch is on. I have to switch the router off and then on again for things to return to normal. then it happens again and again.

Nov 7, 2015 1:17 PM in response to Winston Churchillby Richgrad,Yes. My router is connected via ethernet cable to my pc. my apple tv is connected via wifi to my router. my pc and router is in my office and my tv and apple tv is in my bedroom, so I cannot connect my apple tv to my router via an ethernet cable if this is what you are asking.

Nov 7, 2015 1:14 PM in response to Richgradby Winston Churchill,That's likely why it reports it finding no network adapter. Do you have a computer with wifi to check for other networks. If you don't have anything that could be causing interference it's probably your router settings, you'll need to refer to the manual for details about changing settings.

Nov 7, 2015 1:21 PM in response to Winston Churchillby Richgrad,I have a mac laptop. but do you need a computer on and running istumbler at all times to block other networks while streaming via apple tv? doesnt make sense for me to leave my laptop running just to stream via ATV. do you think that other networks are causing this issue? have you heard of this issue before? as I said, everything has been working fine until now...

You can't block other networks, you are just using that software to see other networks and what signal strengths they are working at.
do you think that other networks are causing this issue?
Can't be sure which is why I suggest looking for them.
have you heard of this issue before?
Yes.

Nov 7, 2015 1:47 PM in response to Winston Churchillby Richgrad,OK istumbler is obviously picking up my network and then 5 others but they are very weak. mine is 55db and the next one is 13, then 10, 10, 3 and 1. still not sure how this helps?
-
Nov 7, 2015 1:53 PM in response to Richgradby Winston Churchill,They may not be a problem if they are weak, which channels are they all on.
-
Nov 7, 2015 1:59 PM in response to Winston Churchillby Richgrad,some on channel 1 and others on channel 6. mine was on auto. default is channel 1, so I have just changed to channel 3. I will test now and see if this fixes the problem thanks. any other advice?
-
Nov 7, 2015 2:03 PM in response to Richgradby Richgrad,Nope. problem still persists. I changed my router to channel 3 - none of the other networks were on this channel. I played a movie and within 15 seconds, the router dropped the signal.
-
Nov 7, 2015 2:12 PM in response to Richgradby Winston Churchill,A network uses 5 channels, the one it states and two on each side, so a network on channel 1 can potentially interfere with one on channel 3. Folks tend to stick with 1, 6 and 11 so that interference doesn't occur. If it turns out it's nothing to do with interference, you might want to give your service provider a call (assuming they supplied your router), but if it was OK before unless you've changed a setting or updated something I can't see it being a setting in the router.

Nov 7, 2015 2:16 PM in response to Winston Churchillby Richgrad,Thanks again for your patience. I will try channel 11. there seems to be another network using that channel but it is very weak (1dB).
No. I bought my router myself from the store and I have not changed any settings.
If this still fails, then what else could it be do you think?
-
Nov 7, 2015 2:24 PM in response to Richgradby Richgrad,I'm sorry but this exercise did not work. I changed my router to channel 11 and checked istumbler. Mine is the only network/router on this channel now. I started a movie via my apple TV and within 15-20 seconds, the line dropped. I walked into my office and the router displayed no lights whatsover. So frustrating.
