LAN/NIC problem

[jandvs]

I sent my pine home with my friend.  Visually, the Pine 64's are identical. They both are Pine64+ 2GB.  He compared HIS to MINE using a couple of different cables long with his sdcard (debian) and mine (ubuntu). Packet loss was determined by pinging google.com (also tried yahoo.com and bing.com with similar results as below).

Pine 64 - HIS
50ft Cat 6 -ubuntu card, no packet loss
50ft Cat 6-debian card, no packet loss
6in Cat 6-ubuntu card, no packet loss
6in Cat 6-debian card, no packet loss


Pine 64 - MINE
50ft Cat 6 -ubuntu card, packet loss (10-28%)
50ft Cat 6-debian card, packet loss(15-28%)
6in Cat 6-ubuntu card, packet loss(8-21%)
6in Cat 6-debian card, packet loss(11-24%)

So this eliminates my "network enviornment" and isolates my pine64 in a known good environment to have a hardware issue.

One more point to clarify on this comparison, he used his Pine64 power supply and mine still showed the issue like when I use my Pine64 power supply.  I'm not saying the power supplies that came with the pine are clean, but the same power supply works on his, but doesn't help the Gbe issue on mine.  I've also tried powering mine from the USB port of my TV/Monitor.  I have no idea what amperage it supplies or how clean it is, but I had the same results.  I have not tried any other power sources.  I don't have scope, so I can't really monitor fluctuations.
