Apple TV not connecting to wifi router - error 3905 - Help!

I have been having intermittent connection issues with my Apple TV since the recent software update, either my wifi router is not recognised or programs/films cut off when the network connection is lost. I was getting 3906 as the error code. I have looked in this forum for answers and I took the advice of one user which was to change the router security from WEP to WPA-2. For them it seemed to fix the problem, however, it has made things worse and I cannot connect to my Apple TV at all now! I get an error message of 3905. I have tried all the usual things suggested, and no, it is not a network problem because all my other devices work perfectly. I have tried ignoring my network, restarting, doing another software upgrade, all to no avail....


I cannot see any other discussions about this error specifically so I thought I would start one. I have to say that I am not the only person I know who has been having problems with their Apple TV recently and I am very disappointed about the radio silence from Apple about it.


If anyone has any suggestions please do post. Btw, I am a computer illiterate so when offering suggestions please talk in basic terms and be specific about any steps I would need to take. I don't understand a lot of the stuff posted here! Thanks.

iBook, iOS 5

Thanks Rudegar - yes I have looked at all of these discussions. I have a couple more things to try, though I have found out that my Apple TV has a serial number which has been recognised to have problems:

The problem I have now is that it is just over (by days) the 2 year free of charge cut off date for replacement. Seems a bit strange that I should start having problems just after I have had it 2 years and just after the free replacement expiry....

OK - so I have fixed it after a LOT of tearing my hair out!


I found out that my Apple TV was definitely working when connected to an ethernet cable - so the issue seemed to definitely be with the encryption. After looking at a number of posts I followed the advice of a couple of people as follows:


1) I logged into my router (in my case a BT home hub manager)

2) Went into Settings/Wireless/Security

3) I selected 'No encryption used' so I no longer had any security on my home network

4) I turned on my Apple TV and in Settings/General/Network I selected my network router

5) Bingo! I was connected wirelessly!

6) I then went back into my hub manager and after selecting Settings/Wireless/Security again, I turned on my encryption and entered my usual password

7) The Apple TV network connection then dropped so I went back into Settings/General/Network, reselected my network router and typed in my password (which it wouldn't accept before)

8) Lo and Behold! I am now connected!

9) To be on the safe side I turned my Apple TV off and on again, and it still works.


I hope these simple step by step instructions help anyone else struggling with this problem.

An update - After fixing my problem and not turning my Apple TV on for a week the problem returned. I ended up going to Apple Care and even though my Apple TV was just over 2 years old they replaced it for me at no cost. Basically my Apple TV was confirmed as one of those which had an identified issue with connecting to wifi. A big thank you to Apple for honouring the recall. I now have a shiny new Apple TV!

You wouldn't believe it. I have worked it out!!


I had read that it was recommended that the IPv6 be turned off but you can't do that in the WiFi TCP/IP settings now. The only options are to change them to "automatically", "manually" or "link-local only".


So then I thought I'd check my router settings through the Airport Utility. I discovered that two of my three Airport Express devices had Enable Access Control checked. When I went in there, the Timed Access Control had an "Unknown" device changed to "No Access". Once I turned off the Enable Access Control the Apple TV started working over the WiFi again without issue.


This must be a glitch or something because I can guarantee I hadn't changed any Access Control for any devices.


Very very pleased with myself!!
