Hi   We have a number of Z3's across our estate. These appliances are in locations where we have 1 or 2 users. Utilisation on the network is low, we generally see max 2/3mb usage. We have noticed that when using real time conference software - Zoom and TEAMs, the audio quality and image is really poor, it lags, pixelates, there's a delay and often the session completely drops. If we replace the Z3 with an MX68 the quality is far superior. The challenge I have is that as these are small sites, with well under 100mb of traffic I hoped the Z3 would be sufficient, however there is definitely a drop in quality on real time apps when used. The appliance are close to 8 years old, im guessing they are just no longer upto the job of modern day comms?   Has anyone else experienced anything like this? Not sure what else to do other than plan to replace the Z3s? ... View more

Hi   We have an externally facing NAT rule that is being attacked from various international locations. We want to restrict traffic from the source countries, however only for the port we are using on the NAT rule.   I can see using layer 7 firewall rules we can block traffic from countries, however is it possible to take this one step further and not only block traffic from a country but only for a particular port? ...

HI,   We recently had a slowness in web browsing and Meraki recommended we change the client tracking from MAC address to IP address, due to 3rd party network infrastructure being present in the network, followed by an upgrade to the latest stable firmware.   We made this change and it appeared to address the issue. However a week later the problem has returned.  I have opened a case with Meraki as I noted the number of reported clients in the dashboard has increased from roughly 300 when tracking by MAC to over 13000 when tracking by IP. We dont have that many client endpoints on our network! Meraki are now saying this is contributing to the problem.....   The question I have is for those who have changed client tracking from MAC to IP address have you seen a huge increase in the reported client endpoint counts?   Interestingly since making the change our CPU utilization has increased significantly as well. We have had to revert the original change. ... View more

Hi   We utilise MR42 APs running firmware 29.4.1   We have an issue with new MS Surface Pro 9 endpoints. When roaming around the office the endpoint drops off the network. We have to disable the wireless NIC and re-enable it to return service. Only Surface Pro 9 endpoints are affected.   Im struggling to see anything in the Meraki Dashboard that assists. We checked the event log for when the issue occurred and identified a Event 7021 Netwtw 10 error  Has anyone seen anything like this previously?   Thanks   ... View more
