To Sergejs :

You have degraded/upgraded on your own. No one knows about this product till now. and no information received from your newsletter for this product.

You did a big change of chipset and look in your existing product. Your website still showing AR7241 based RB 750.

I need to send all information of this product again to my customers. :frowning: :frowning: :frowning:

You have not intimated to the distributors before.

For anyone still wondering about the specification for this new RouterBoard. This is from a freshly unboxed unit.

What’s WRONG with these new boards?

  • It looks like we now have to use “flash/” subdirectory and the root filesystem is some kind of ram disk (nobody told me, and had to find out the hard way).

  • We’ve got four of them and for some of them they just don’t work. Or after resetting tens of times they might work for a while…

  • Another bug. Put this into test.rsc:

/interface ethernet
set [find] master-port=none
set [ find default-name=ether1 ] name=wan1 master-port=none
set [ find default-name=ether2 ] name=wan2 master-port=none
set [ find default-name=ether3 ] name=LAN master-port=none
set [ find default-name=ether4 ] name=lan1 master-port=LAN
set [ find default-name=ether5 ] name=lan2 master-port=LAN

And now run

/system reset-configuration no-defaults=yes run-after-reset=flash/test.rsc

The result is that ethernet LED don’t work anymore. Rebooting does not help. The only solution is to reset.

Hi,
just put my hands on this one:

Should I set cpu frequency to 850MHz

/system routerboard settings set cpu-frequency=850MHz

or not?

Is there any other solution to restore the led functionnality ?
