It has been a big disappointment with CCR-1036-12G-4S. We have been facing lot of issues with this equipment. Once configured it runs smoothly for a week days and some or other problem arises. Today we do have a different problem with it. There is a packet loss in hotspot clients. After much of rechecking the firewall settings and everything we got to know that whenever somebody click on the interface tab in winbox there is a packet loss or latency with the gateway and internet, suddenly bandwidth utilization has also problems. Got wired with this behavior. Can anybody help us with this. ..
