Hello all,   I am coming here after raising several support cases about two major issues, and not really getting anywhere closer to a solution, so I am hoping someone here had similar issues in the past, and was able to resolve them somehow.   We have about 50 MR30H access points spread throughout almost as many remote sites. We first started noticing issues around February of 2020. In a nutshell, the MR30H APs will report they are connected to the Meraki Cloud, and to our MX-100 running as a VPN concentrator at the main office. The MR30H APs have wireless clients connecting to them, and also have wired printers and desktops connected to them. In most cases, these remote sites have separate, company owned and controlled internet connections used by the APs. In some cases, we need to work with the remote site's IT department to set up a port for the APs that basically just dumps straight out onto the Internet for us.   The first major issue is with DHCP. I have our DHCP server set up at the main office, where the MX-100 is. Sometimes, but not always, the MR30H APs will report that clients are on a particular VLAN, but they never get an address from the DHCP server. They will fail, then pull one from the AP itself in the 10.x.x.x range, which isn't right. Sometimes the same AP will "allow" the DHCP lease to come through, sometimes it wont. It seems to be more of an issue on wired clients than wireless ones. Then the next day, that AP is fine, but a different one will start acting up the same way. Support claims my DHCP server is not responding properly, despite it working fine for every other client in every way, and its basic settings not being changed for years.    The other major issue is communication between wired and wireless clients. Specifically, printers. We have wired printers at many of our remote sites. The wired clients can always connect to the printers just fine, but wireless clients on that AP, and also clients at the main office, cannot ping or connect to that printer *until* I ping it using the Ping tool on the AP itself. I get "destination host unreachable" until I ping from the AP, then suddenly I get responses on wireless and remote clients. The wired desktops never have an issue, and the printer always responds for them. If I stop pinging for 60 seconds, I go back to "destination host unreachable" until I ping from the AP again. The wired desktops never drop a single packet to the printers during this time. Many support cases and hours of packet captures with support later, and still no answer. This is happening on multiple MR30H APs at multiple sites, with multiple printer makes and models.   I have been told: To put the MR30H APs into a separate Meraki network for each site To create a VLAN and Subnet for each site, and put both wired and wireless clients on that VLAN and Subnet To make a separate DHCP scope for each site To avoid using "wired only" SSIDs and instead use Enabled with Hide SSID for any AP port profiles using those SSIDs Update firmware That MR30H APs are finicky and weird (came straight from support)   I have done all of these things, but nothing has helped. Has anyone run into issues like this? I'm ready to buy 50 FortiGates and set up proper site-to-site VPNs if I can't get this working.   Thanks!   ... View more
