Can’t stream from my router to my RPi3!

Hi Friends,

I have a problem and I’ve ran out of options, so, here I am.

I have a WRT1900ACS with a 2TB HD connected and streaming contents. Then, I have a RPi3 connected thru wifi from my Living room.If I’m on my bedroom and I open videos on my LG SmartTV using router’s wifi, it opens and plays everything. From my RPi3 I simply can’t watch anything! I used to have it connected thru cable but I had to change my router to a litlle far away and cable is no longer a possibility. Everything is working fine thru wifi. I used to have this HardDisk from my router mapped thru fstab to my local file system but after changing to wifi, I’ve started having this problems. So, I’ve removed it from my RPi3 and tried to map it from my Kodi using SMB but the same problem happens. Sometimes I can watch something like 20 minutes of something. Others, doesn’t run for more then a minute or so.

I have tried to change cache and memory settings using advancedsettings.xml but didn’t solved the problem at all. I have no more ideas on what to do. Can anyone maybe take a look at the logs and see if maybe some ideas come up?!

Thanks a lot in advance!
