Эпл тв ошибка 3902

Same problem here and also problem with network drop outs

I also have the same problem. Maybe the password is too long, but it works on all my other Apple computers, my iPhone, etc. Using WPA2.

I am using fixed IP addresses, and my router uses MAC filtering. I have added the MAC address given by the Apple TV, so shouldn’t be a problem.

One thing I notice is that after I set up the IP address, it doesn’t show in the listing, although it is there when I go to check the setup.

The Apple TV can see the network, but signal strength may be low: Manual doesn’t say what it should look like I get about 6 hollow squares. Do they fill in solid to indicate strength?

Basically very frustrating, as insufficient tech details for when you have trouble, and you have to have it connected to your TV to be able to set it up. If the thing needed to be connected via USB, then either a micro port should not have been used, or a cable adaptor supplied.

Got it going!

First, note “Apple TV: Troubleshooting wireless connections” <http://support.apple.com/kb/HT1595>, where it points out that the Apple TV 2 won’t work on Static IP addresses without a suggested work-around. I didn’t have too much success with that, either, although I only tried it once.

My solution was to switch over to DHCP, but reserve the specified IP addresses for given MAC addresses, while still using MAC filtering to prevent any outside device from being allowed to join the network. That meant changing 9 machines to DHCP rather than Static, but the effect is now the same as if the addresses were Static, since they are reserved for the specified machines. My reason for having fixed IP addresses is that it simplifies software security maintenance for me.

This solution may not work for your WiFi Router/Firewall if it doesn’t support reserved DHCP addresses and you need to control your IP internal addresses. I am using a D-Link 2642B ADSL2/2+ Wireless Modem/Router/Firewall/Switch.

I am now downloading an update to my Apple TV 2, which, of course, may actually fix what was wrong in the first place. 🙂

Same problem. I have resolved the issue by disabling the sleep mode and by never shutting down the apple TV:

Since then, the problem never occured again. Note that I am using the latest Apple TV firmware available.

I have a linksys wi-fi G Router.

Same problem here. Please help, on our way to buy an ethernet cable.

Called Apple twice, they didn’t seem to know what to do. Just told us to shut down everything and restart, and to reset Apple TV. They also told us to shut down the network security while trying to reinstall. Well we actually were able to get onto our network by closing ALL of our network security, but that’s not a good idea. And when we turned the network security settings back on we lost Apple TV. We ended up getting an ethernet cable, attaching it to a second port on our router and from there to the Apple TV. This seemed to get us a little further along, but got a new error message about we weren’t HDCP compatible? Out of desperation, we decided to try a different HDMI port on our TV and it is now working!! So, not sure if we had just tried this in the beginning (a different HDMI port on our TV) if maybe the wireless would have worked, but we are just to exhausted at this time to go see. Just thrilled to be able to rent some freaking movies.

I had a bit more hassle after sending my first exultant message, as it wouldn’t connect again after power off the next day. There were a number of errors in my router config, including the wrong MAC address in my MAC filtering inclusion list (got corrupted, I think!), but couldn’t get it up even after fixing that. I then
reset the Apple TV and started over, including re-entering the looong passphrase I have for my WAP2 security protocol. What a pain!

It did come back with some fantastic IP address that wasn’t even on the Internal Private Network lists (eg, 10.1.1.x, 192.168.xxx.xxx, etc), so I set the Apple TV to static mode and reset all the addresses and masks to 0. Still no luck.

Then I remembered watching my Modem stats screen and seeing that it didn’t have some of my connections listed as active in the DHCP table, even though these connections were up and running. I could get them on the table by going into the Network (Advanced) Pane in System Preferences and renewing the DHCP Lease. Of course, you can’t do that on the Apple TV. However, you
can reboot your modem to refresh everything. Did that, and guess what, Apple TV came up smiling! The WAP2 Password was clearly stored somewhere, and the reboot of the modem clearly triggered a response.

That was last night (or should I say, very early morning!). I shut power off to my TV and HiFi when not using, and this also shuts off the Apple TV. I just booted both up this morning and the Apple TV came up smelling like a rose.

Hope this helps a few people.

I fixed mine by turning off all the other things I had connected to my router. And then I started with the ATV first and it worked.

This worked for me too. I had to turn off the Apple TV, turn off the wireless on my iphone and ipad and turn off my laptop. Then unplugged my wireless router and plugged it back in. Then turned on Apple TV first and it worked perfectly! Thank you!

This worked for me, too. Thank you, whitney1980 — I followed your steps exactly.

I did Reset>Reset All Network Settings and fixed it. You do have to put back some of your logins but it was super easy to fix.
