Why does my apple tv 2 lose network connectivity?

This is not true. Network is not always an issue. The Apple TVs especially the 2nd gen have had issues with connectivity since the 4th gen came out. I was told at multiple Apple stores Apple does not have a way to trouble shoot issues with Apple tvs, they just replace them if resetting the system doesn't work and it still under warranty. I have had this issue and even moved and still have the issue. Why does everyone go right to a network issue even after multiple people say they have no issues with any other wifi or LAN connected devices!!

Yes, in the majority of cases that will be the cause. No, the 2nd gens have not specifically had such issues (there were a select group of 3rd gens that did) and were discontinued long before the 4th came out. I have had many units, been a part of this forum for years (with no such widespread reports) and done/continue to do vigorous testing. It is a network streaming device and when there is an issue that is where to look. I find it hard to believe you were told that, as that is a completely false statement. Other devices working does not rule out a network issue, and one can easily find instances where the ATV is working fine but another device is showing these symptoms. You will need to do proper troubleshooting.

Welcome to the Apple community.

Have you tried the Apple TV in another location.

Actually, I meant in another location altogether, such as your office or at a friends house. My suspicion is that it is a network problem, however you seem convinced it's a hardware problem. Locating the Apple TV to another location may well determine this.

There are many things that could do this, including other devices that have been introduced into the location, neighbouring networks, software updates et cetera et cetera. However if you have a number of friends with an Apple TV that is working in their location, that would be an ideal opportunity to test yours.

I have just recently started having this problem as well. I have had my appleTV for about 3 years or so. I have never had this problem. It just loses its network connection and the only way I can get it to reconnect is to restart the appleTV device. I have two other computers and a sony dvd player and an iPhone that all connect to my home wifi and none of them seem to have any problems at all. In fact I go so fed up with the network drop that I went up and finished watching my movie on the dvd player via Netflix.I have tried rebooting my router and that has no effect on my appleTV. I have tried going to Network and trying to reconnect to my network, but it doesn't work until I restart the appleTV device. I have tried to resent the appleTV device and that didn't work either. I have tried to do a software update and that either comes back unsuccessful or its all up to date. I have tried unplugging the appleTV device for 24 hours and there was no luck there. I have tried connecting to a different network and that didn't work. I know the signal is good to the appleTV as I am sitting right next to it on this computer and I have full strength WIFI at this computer. I have tried checking all the connections and they are all tight and clean. I have tried moving the appleTV device to a different tv and I still have the same problem. I am guessing that this device is just at the end of it's life at this point, but 3 years seems like a really short lifespan, even for apple.

In order to verify the signal you would need a diagnostics report from istumbler, netstumbler or similar. Did you test at another location and/or at Apple?

didnyou ever get it fixed? My device has started to lose signal/connection constsntly. It worked great for a couple years and now it drops connection all the time. So im wondering if you found a fix that worked?

You will need to troubleshoot your network, issues can come at any time
