We recently upgraded all our highsite side equipment to version 6.44, and ever since the upgrade, I have had 4 routerboards(3PowerBOX & 1 Powerbox Pro units) start giving authentication failed - Radius timeout on PPPoE dial ups. It is not the radius server, and I kick connections on other towers and they reconnect immediately. The issue on resolves if I reboot the PowerBox.
Is there a bug in ver. 6.44? As a temporary measure I have to create a secret for the client, as I can not reboot the router each time during busy time.
