## Hardware-Bug
|
||
|
|
Anscheinend haben alle Geräte der Revision XW von Ubiquiti einen Hardwarebug im Ethernetchip. Das betrifft sowohl die Nanobeam M5, als auch die Nanostation LOCO M5.
|
||
|
|
Die Nanostation M5 ist nicht betroffen, da in ihr ein Ethernetswitch verbaut ist.
|
||
|
|
Ursprünglich dachte ich der Hardwarebug wäre nur dann ein Problem, wenn wir die Geräte mit OpenWRT bespielen, da eben noch kein adaquater Workaround in OpenWRT existiert.
|
||
|
|
Mittlerweile weiß ich aber, das auch mit der orginal Firmware (AirOS) von Ubiquiti der Bug ein Problem darstellt. Sie lösen das Promblem mit einem sehr schnellen Neustart des PHY.
|
||
|
|
Aber auch hier verliert die Antenne kurz ihre Ethernetverbindung. Wirkich akzeptabel ist das nicht.

## Flashing with OpenWRT
|
||
|
|
It is possible to upload the image via AirOS. But after i did that, i was unable to connect with the device.
|
||
|
|
I needed to open the glued case (a hammer did the trick) and connect through the serial console.
|
||
|
|
After changing __/etc/config/network__ from
|
||
|
|
```
|
||
|
|
config interface 'lan'
|
||
|
|
option ifname 'eth0.1'
|
||
|
|
```
|
||
|
|
to
|
||
|
|
```
|
||
|
|
config interface 'lan'
|
||
|
|
option ifname 'eth0'
|
||
|
|
```
|
||
|
|
|
||
|
|
everything seems to work fine.
