My Slingcather says it is running at only 766KBps. Which seems very slow on a great cable modem connection that speed tests over 20MB and has ping times of 10 msec. What can I do to get Slingcather to go faster (use more bandwidth) - so the quality looks better on the HDTV?
Have you tried using the manual quality settings rather than auto?
Your ISP could be throttling your connection too (do you really have 20MB/s upload, that's 160,000Kbps). Try changing the port Slingbox uses to something less likely to be throttled; 443 or 22 for starters.
