Dear Team,
At one of our sites, we are currently utilizing the RB2011UiAS router in conjunction with Ubiquiti access points, configured through OSPF. We’ve encountered an issue where some of the ports periodically degrade from 100Mbps to 10Mbps, and the only way to restore them is by rebooting the Mikrotik device. We don’t believe this is a cable-related problem, as a reboot consistently resolves the issue. We would greatly appreciate your assistance in understanding the cause of this problem and finding a permanent solution.
Thank you for your support.
Best regards,
Velbon
