I'm on a 100meg connection. I've changed my DNS to Google's and Cloudfare's with no change. Using a Dreamlink T2 with 10 sec buffering turned on. Beams have moved servers for me (to a server closer one to where I live) but it's still buffering every 20-30 seconds on both HD and SD channels.
I also have Eternal TV and it buffers maybe once or twice a hour for a few seconds but otherwise no problems.
Any other changes I could do on my network/router to fix this?
I can't imagine there being many ex ACE people wanting to help you here bud. My advice, get rid of Beams before they too close down and run off with your money.
Look into Epic / Flawless / Vaders / Fab / Nitro
