Vero 4K+ losing network while streaming

Box is losing wireless connection after about 1hr of streaming anything. No connectivity (ssh or otherwise) until rebooted. Just now I took a look at old log upon restart using nautilus and saw all zeros with a warning that I did not have permission for the file!! I’m going to try again and hopefully get a good log to post here. Only happening on the 4k+ and not the 4K which has identical config.

Note that I’m not experiencing any buffering issues prior to losing connection.

Can’t advise without a log but if files are being deleted you should check the device isn’t port forwarded
