"No network detected" on Apple TV 4K

I am no expert on any of these issues. However, I will not quit on anything and spend a lot of time and in some cases money on issues. The problem with being unable to connect to the WIFI on my APPLE TV 4K was very frustrating to say the least. However, a recent call to Apple Support, may have been the most informative call and outcome on this issue to date. The support person investigated a number of issues and found that the WiFi router I was using was "Too" old and obsolete. Like putting a Tuxedo on a Pig? It was over 5 years old and had a "G" rating. Not sure about all of that info, but it was suggested to procure a new router and I did so. The Best Buy reps. suggested purchasing the NetGear55 over the Apple AirPort Extreme. Went with the NetGear. Had some issues ( Passwords !!!??? ) with the installation of the new NetGear55 ( 2.4 and 5.0 GHZ ). However, got through all of that and finally have been able to connect to the AppleTV 4k, with no problems so far. Using the 5.0 GHZ part of the router. Crossing my fingers. I am not inferring that my ( Hopefully ) fix is a cure all but so far it has worked for myself. Hope this information may help others in some way.👍😎

I changed dhcp renew to never on my firewall, changed to a different network and back again to the fortigate and touchwood the problem seems to have gone for now

Hi. The last update to tvOS was version 11.2.1, issued on Dec. 14, 2017. So, unless you deferred the update, there has not been a recent update. Could you try switching to a 5 GHz WiFi network, if not already on one? That might reduce possible interference problems.

Had the same problem today. reading a bunch of stuff. I unplugged the router and started it again and problem solved...sort of. Now it is losing the connection every so often. something is going on but not sure yet how to fix. anyway can try the router restart

This is a user forum, you aren't addressing Apple here nor will the respond. Another device working doesn't rule out the network. Did you run a diagnostic report? Test on another network?

I have had some luck it seems 🙂 After switching everything off and having had a cup of tea i decided to check through the apple tv settings menus.

In there (and i can't remember where) is an option to set the apple tv settings to suit your tv. I pressed it and it seems it has adjusted settings through the apple tv - Everything now works, I no longer lose the network, and have had no problems since. I m using a smart LG tv btw.

Was really finding this frustrating, persevere and i hope you will all be rewarded.

Apple c'mon help these folks out a little more please?

This JUST started happening to me last night Jan 14th, 2018.

Sorry if this was a repost.

WiFi works fine and stuff plays fine. But occasionally, streaming does in fact stop. Pressing play and ignoring the "No network found." message works fine.

My Apple TV 4K has been working flawlessly for months. I'm sure it's a new bug or patch bugaybe issued for the Meltdown or Spectra stuff.

I am connected via 1Gbps ethernet. There is no network issue as no other internet appliance has issue. It is clearly an Apple TV (4K) issue.

I JUST started having this problem last night. It's been non stop. Thing is, it doesn't stop streaming. It just complains. Occasionally have to just press play again and it resumes. This is getting annoying though.

connected to a fortigate firewall with dhcp via 5ghz wifi no timeout and I still get this every 45 seconds approx, doesn't stop streaming but is very annoying. Signal is max strength on the bars on apple tv

I have the same problem, so having read other threads in other forums i purchased a quality ethernet cable - no joy, same problem the network appears to drop. Strange as my Apple TV3 works just fine with the same connections/wifi setup.

I think Apple needs to step in here and provide assistance....

WTH!!! Getting the same S..T. Thought it might be the HDMI cable, new BTW. Changed the to the old HDMI cable ( Yesterday ) and it looked like the problem was resolved. Not so! Again today, while switching to Apple TV, I can get the same "error" message you folks are getting! And, looks like my Apple TV remote freezes up and I can't scroll. Getting a pop-up stating that "Remote Connection Lost" and then goes back to "Remote Connected" but still can't maneuver with the remote. Very frustrated with this product, right now!!

Above you stated you were on wifi. Other devices working doesn't rule out a network issue. Apart from this thread I have not seen any other reports.

Thank You! I have a Brand new LG 55" Smart TV. Is your tv "new" as well? Sometimes these remedies only serve certain era TV's?

Yes it is a 55" too, lets hope it helps a lot of others too
