Hi -

I am having a problem with one of our RB800 boards. It is the second board to present the same problem.

We have 2 sites connecting to the RB800. It seems as if the ethernet port on the RB800 periodically times out, causing our VOIP phones to disconnect.

When no sites are connected the ethernet link is stable, however when ether sites or both are connected, the ethernet port times out.
The traffic coming over the wireless is minimal.

Please can somebody assist urgently.

Please describe or draw network topology diagram. What RouterOS version is it? Do you have any mangle action=mark-packet rules? Is there a masquerade NAT configured on this router?

We are using OS 4.11

It is a basic setup.

RB800 setup as AP Bridge.
2 RB433 boards set to bridge connecting to RB800. The wireless link from both RB433 is stable 100%. However it's just the ethernet port on the RB800 that seems problematic.

When I ping a pc on each of the RB433 networks and ping the ethernet port on the RB800 from the RB800 side; all show the timeouts at the same time.

No rules configured. Regarding NAT -- nothing was configured manually.

Please upgrade and test with latest v4.17:

Thanks.
I will upgrade and let you know.

When uploading the update, it stays on 0b of 11.9MiB uploaded, then get disconnected.

So it seems that traffic through the LAN port is causing the issue here. I will try upload via the RB433 link and get back to you.

Managed to update to 4.17 -- Problem still persists.

Please generate and send supout.rif file to support@mikrotik.com together with report of this problem.
