Hi –
this is just a guess. Many network issues are more complicated then just “ok – just click on this and you will be ok”.
I have a router (used to be Apple Airport Extreme, now it’s a Synology RT2600ac), which connects to multiple Apple Airport Express boxes as repeaters. I have 3 Apple TV’s. ONE of the Apple TV’s gets its ethernet internet connection from one of the Apple Airport Express boxes. Within the last 6 months, this Apple Airport Express (which connects via WiFi, not hard wired internet) – ALWAYS loses the connection (every couple of days). The only reason I even know this, is because I cannot get that Apple TV to work in that one room. IF you go into the Apple TV Menus (using the remote, not your phone or iPad) – you can see that it says “no network found”. So I UNPLUG the Apple Airport Express, wait 30 seconds, plug it back in, let it reset, and all of a sudden, the Apple TV now has it’s ethernet internet connection, and then it works again.
In a professional environment, this is unacceptable. Things have to work.
SO –
1) run a WIRED Ethernet signal to that Apple TV, don’t allow for WiFi access (you say “well, that’s almost impossible” – well, make it possible
2) Apple Airports and Apple TV’s are old technology, and have become unreliable (you say “well – it used to be reliable at one time”) – well, things change.
My other Airport Express repeaters and Apple TV’s get a wired connection from a central 1G switch. Never have any issues with those.
If WiFi connection becomes a “must” – get rid of your Apple WiFi network, and switch to a modern 1G “ac” WiFi network that is a MESH wireless network (like from Netgear, Ubiquiti, and others).
You say “I don’t want to spend any money – I just want my old stuff to work” –
welcome to the world of electronics. I go thru this, everyone goes thru this. Tough noogies.
