Kanaal verhuisd (140), nu goede TX/RX op Graficall nano.
Pingen tussen nanostations van Graficall en WBRotary gaat prima, ook van nanostation Graficall naar node Graficall. Maar tussen nodes veel packetloss: 321 packets transmitted, 78 packets received, 75.7% packet loss

round-trip min/avg/max/stddev = 2.508/3.353/6.643/0.730 ms
Lijkt dus probleem bij Rotary (kabel?).

Link WBRotary - Graficall blijft problematisch:

maar geen packet loss (meer), ook niet met grotere pingpakketten (-s 2048).
