Packet loss on lan port - Hiren - 09-06-2016 I have a pine64 + 2G that pulls ~20% packet loss regardless of the OS. This makes it impossible to run updates or even browse the web. Its sister board that I revived at the same time works perfectly with the same SD cards inserted. Is there something I can do to fix this?

That depends, please post your setup info... ethernet (y/n) gigabit switch (y/n) If your boards are plugged into a GbE switch, then force the board that isn't working into 100mb/s. You can do that by using the ethtool, or modifying your eth cable. Otherwise, you may have a defective board. RE: Packet loss on lan port - Hiren - 09-06-2016 Mark, Its been tested across two boards. In multiple setups. Gigabit Switch and 10/100 switch. cat 5, cat5e, as well as cat 6. I have tested each setup with my working board by swapping cables and SD card so the entire setup is similar minus the few inches for physical separation. RE: Packet loss on lan port - MarkHaysHarris777 - 09-06-2016 You can force 10/100 for the board that does not work, with the gigabit switch, by doing one of two things: 1) sudo ethtool -s eth0 autoneg off speed 100 duplex full 2) modify your eth cable by cutting (and removing) the blue and brown pairs, which creates a four wire 2 pair cable (green and orange 1 2 3 & 6) which will fall into 100mb/s by default; what people around here are calling the 'hackafix'. (I think that is funny) I doubt seriously that your board is dropping packets on the 10/100 switch; not getting those reports from anyone else. You may have a seriously defective board. Obviously there is a soldering problem on these boards, and obviously many gigabit boards are not functioning anywhere near 1000mb/s. Your board may be even worse; although, I have not seen that yet (yours would be the first reported).

I thought I had tried this before I emailed support 3 month ago then shelved the unit. Looks like ill be able to start building my playbox enclosure this evening. I'll just have to remember this in the event I ever decide to take it off wireless. Thank you so much. Cheers! |
