Constant Network Flapping

[mplinuxgeek]

My SV08's network interface is constantly going down/up, its done it since I got the machine (11th of October), I've tried many things to resolve it:

1. Replaced ethernet cable
2. Different switch
3. Set port speed to 100Mbps Half Duplex
4. Tried a fresh firmware image
5. Tried USB network adapters (USB Network kernel modules aren't included with the image and due to /boot being fat32 you can't install the correct packages)

Unfortunately wifi is too slow on this board to make the camera stream usable, I only get 1-2 fps over wifi yet its in the same room as an AX1800 access point.

sovol@SPI-XI:~$ dmesg | grep "Link is Down" | wc -l

sovol@SPI-XI:~$ uptime
 12:28:05 up 2 days,  5:58,  2 users,  load average: 0.05, 0.15, 0.16

Output from dmesg:

I second that.

A deeper view into what happens shows that the printer scans the WIFI every <random value ~12s> with a randomized MAC and if it sees more than one AP it hops between them by random. Doing so the printer ignores that he may already be bound to an AP and also ignores the signal strength.

That leads to a lags in the connection.

Even switching off wifi and make use of wired LAN with a fixed IP did not stop this.

Another bug even with a static IP, the printer did a DHCP request and adds a second IP to the eth0 interface.

A more clean setup for the debian base system may help a lot and save sovol tons of men power.
