OAK-1-PoE problem with read stream

jakaskerl
I open port but still it didn't help.
On third script run, model start work, but with out mikrotik, run always.
(Also, seems strange to me (perhaps it's ok), you save set the gateway to 1.254) - i use different input internet router, but it didn't help.

BR,

I get that info from raspberry

"pi@pi:~$ ip rout

default via 192.168.1.254 dev wlan0 proto dhcp metric 600

default via 169.254.1.1 dev eth0 proto static metric 20100

169.254.0.0/16 dev eth0 proto kernel scope link src 169.254.1.250 metric 100

192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.104 metric 600 "

Can be that problem if i don't have last line?

Yes, i can ping, but when start model get that error.

Hi, I found one problem, when configuration range 10-100Mb camaera work good. If I put 1Gb, then momentaly get error.
But 100MB, give only 17 FPS, not 26 FPS in 1Gb mode.

jakaskerl Test code is not large, put it all.
currant-yolov8-1107-480.blob - got 1600 picture 5,79 MB file size.
Also run small *.blob file = 600 picture ~4MB file size, but problem same.

Router is 5-10 y/o, maybe it get some problem with connection.
Ok, i try use wireshark and check where is packet loss.
Yes I add half half-duplex for 10/100/1000, same problem, when disable auto negotation, camera lose ping and any connections is not available.
