Computers publish data onto a network using things called "shares" (which usually have name) - sometimes the technology underlying the mechanism uses processes to "advertise" the shares, sometimes not.
At present time, there's basically three types of technology (called "protocols") used to create network shares, one called CIFS/SMB (often and somewhat inaccurately known as the "Microsoft" protocol) one called NFS (which tends to be mostly used on UNIX and derivative machines such as Mac's and NAS's) and a relatively new one called DLNA which is biased towards media sharing (and has a bit more automation in it to ease use for domestic consumers how, naturally, are mostly not IT professionals.) A lot of modern consumer NAS's can offer all three!
DLNA is often used by "active" media servers such as Plex etc. however it doesn't have to be. As such, sometimes such media servers have "active" processes behind them that mess with the data in flight.
CIFS/SMB (and NFS) are "general purpose" sharing mechanisms that can be used for any type of file, not just media.
So one way to assess whether the media server behind DLNA (if there is one) of the DLNA protocol is causing your problem, would be to use such as alternate sharing mechanism and take the media server process and/of DLNA out of the picture and use an alternate protocol that is still pulling the data over the network, thereby confirming that the network proper is not the cause of your problem.
From memory, to create a CIFS/SMB share on a Windows computer, pick a folder (any folder) right click it and in the "properties" somewhere there's a button to click to "share" said folder (you can name the share anything, though by default it's often the named the same as the folder.) Unsharing is much the same process in reverse.
Then from your player, depending how it and your network are functioning, you should be able to either "browse" the network as see what shares are available and connect to them or you may have to "teach" the player the computer and share name - but it usually is not difficult to do. |
