Why is one of my two Apple TVs not seeing my DLNA devices? [closed]

My network has a Synology NAS running a DLNA server and two Apple TV 4K devices (identical hardware, running identical firmware).



One of my Apple TV devices can reliably see the Synology DLNA device: it's listed in the tvOS VLC app as well as in all other DLNA-capable applications. However on the other device (located in a different room in the house) my DLNA devices are only listed very occasionally or rarely, so most of the time they're not listed in the tvOS VLC app, also a DLNA diagnostics app I put on the AppleTV reports it didn't find any DLNA servers in the local network.



The network topology for both Apple TVs is similar: they're both immediately connected via wired ethernet to a gigabit switch which then both connect to the same gigabit switch.



Network settings seem the same on both Apple TVs (excepting IP address) and they're both using the same DNS server (a Windows Active Directory domain controller DNS server).

How to calibrate 16:9 built-in touch-screen to a 4:3 resolution?

Image
up vote 0 down vote favorite I need help with an issue we're facing in a project where we are moving from a Windows-based POS environment to one running on CentOS7. The problem consists of a number of factors, please find the details below: The supplier of our POS application will only deliver an application that is hard-coded to run in a 1024:768 4:3 format. The hardware we are using is a POS unit from HP that has a built-in 16:9 touch-screen. The employees using this solution is not supposed to see nor have access to anything but the POS application. Our sales organization demands that touch is an available feature when going live with the new POS environment. Going further into this, allow me to explain what we have encountered on the way trying to achieve the goal of having a touch-screen: We've simply change...

QoS: MAC-Priority for clients behind a repeater

Image
1 1 I've setup a wireless network using a Linksys-Router (DD-WRT) as an AP and a TP-Link repeater for range extension. To manage bandwith for specific users, I've setup QoS-Rules on the AP (DD-WRT) using MAC-Priority: However the AP shows only the Repeater's MAC and the MACs of users inside the AP-Range. The MAC addresses of users behind the Repeater are not listed : The purple MAC is not listed in the AP-Clientlist. Its related to a device connected via the TP-Link repeater. Q: How can I setup MAC-Priority for repeater-clients? Do I simply add the purple MAC in AP-MAC priority list although it's not listed as a client? I want to setup specific priority instead of giving one priority for all clients behind the repeater by adding the repeater's MAC in the MAC priority list in the AP as ...
