I recently upgraded from a 100Mbit router to a 1Gbit router, the Airport Extreme. Right about since then I have started to experience serious video lag and frame drops when playing .mkv files (both large and small). With the previous 100Mbit router I used to stream 1080p .mkv’s to the WDTV Live via a wired eithernet connection from a SMB shared folder on my iMac and all seemed to work well. Until now.
To test my routers network performance I hooked up a USB drive to it and copied a 5GB file to it. It took me 5 minutes to copy the file to the drive via ethernet and I checked the Network Utility that showed outgoing data rates to be about 25-30MB/s on average. I then hooked up the same drive (with the same file) to my WDTV Live and accessed it again via network from my iMac to try and copy the file back again. The data rate was about 3MB/s on average, sometimes spiking to 5MB/s but often dropping to 500-700KB/s. Why is this happening? Do I have a “bad” ethernet cable or is the hardware on the WDTV really that bad? I guess the interface is 100Mbit and I would understand not doing “the full hundred” because honestly not many devices ever achieve anything close to actual 100Mbit, but 3MB/s is bad even for the cheap stuff!
Also, this happened around the time when the previous firmware update came out, the 1.04.10 I believe.
Is there anything else I could do to try and improve the performance? Try and switch cables? Try NFS sharing with the B-rad firmware?
