Check the DNS connectivity in that case.     I face the same issue sometimes and I figured out that the ISP was facing some sort of Internet issue. Anyway, the MX won't lose Dashboard connectivity.  ... View more

yes this works on LAN port to. You need to have a MX/Z and enable it at the Securtiy & sdwan > access control. make sure the port is set to access and has the correct vlan set, the same as you set for the access control. ... View more

Not sure if I followed what you are after, I do see the one dropped ping in the 2nd screen shot.  ICMP in general is low priority.  Successful pings are always a good thing, but occasional unsuccessful pings are not necessarily a bad thing.  Dropped pings can be caused by any number of L1, L2 or L3 issues.  Would have to do further testing with something more reliable than ping alone.  In what way are the connections unstable?  I'd suggest running some other live tools from the tools tab of the MX itself as well as certain other tools on the end PC through the MX.  You can open a case with Meraki Support to further diagnose any connectivity issues, including upstream from the MX, they can examine the connection monitor and advise if it looks like something is going on with your ISP connection.  Also if you have an MI (Meraki Insight) license running on the MX, look over your WAN Health stats. ...

As well, the Clients page shows average traffic over time whereas the uplink page shows real time traffic. Peaks and the valleys are combined smoothed out to show what traffic looks like over longer periods.    If you have 100Mbps of traffic for five minutes, and 0 Mbps of traffic for five minutes, then to graph that over time you'd have show 50Mbps for the 10 minute period.   ...

@PhilipDAthif you want to make the experience really terrible, I'm sure you can put 128 clients on each radio, i.e. 128 on 2.4GHz and 128 on 5GHz, or am I reading it wrong?   In an entertainment environment we follow guidelines of 30 client per radio for general web browsing etc. and 10 clients per radio for VoIP traffic (internal phones and radios).  This usually provides a decent quality whereas when we have nearer to 60 clients on a radio it commonly leads to a poor user experience. ...
