I have checked again. There is no DHCP server on the WLAN client either. ether4: received DHCP server message on untrusted port from source IP 0.0.0.0, MAC xx:xx... The MAC "xx:xx..."address shown is my second PC connecting via WLAN. It also gets an IP address. I can not explain why it com...

Hello we are using a CRS328-24P-4S+ (FW long term 6.48.6) and have a question about "DHCP Snooping". I understood that only the port where the DHCP server hangs needs to be set to trusted. In our case DHCP server is connected to port 1. DHCP snooping is enabled ether1 (trusted port): Ubunt...

what exactly is meant by this? What is new with POE firmware? Have these bug viewtopic.php?t=179211 been fixed?

I noticed the problem with RouterOS. I then changed to SWOS, hoping that SWOS might be the solution. But even with SWOS the problem remains.

Does the Antenna reboot ? In other words, does it loose power ? or just the port flaps ? The AP will then reboot (losing power). AP that are connected via a 2m network cable (i.e. very close to the switch) will also lose power, AP down/up. LAN (without POE) work without problems. So there must be s...

I would be happy if you report if there is a solution. Mikrotik playing silent bob game ;) So I buy power supply and manually injecting power into specific cables. Are you sure that this is the final solution? Port Flapping are gone? If you look under Log, have the DOWN/UP messages disappeared?

We are running Ligowave NFT AC2 and AC3 with Mikrotik CRS328. The access points are powered by CRS328 POE and there is a daily dropout! Or port flapping (down/up, down/up...). Nothing helps, forced on, high, other network cables...everything already tried! All attempts unsuccessful! Ligowave AP are ...

I would be happy if you report if there is a solution. Because we also have POE problems... connection with Ligowave AP (52v) -> viewtopic.php?t=179211

We have several CRS328 switches through our building that are connected via fiber optics. The switches are connected with 10gb SFP module.The switches are in bridge mode. No special configuration, no Firewall..., HW Offload is enabled. The data transfer is very slow, it does not even reach 1gbps. Te...
