Had another support call on Tuesday. This is the third call where they have taken packet captures, then told me the engineering/dev team will have to analyze. This was for the communication issue between wired printers and wireless devices connected to the MR30H. Wired devices can always ping the printers perfectly, with no dropped packets. Specifically, I test a wired desktop PC pinging a printer. When a wireless device attempts to ping that same printer, the first two packets time out, then I get recurring "Destination Host Unreachable", even though all of these devices are using the same VLAN and subnet. Sometimes, after about a minute or so, the printer will then suddenly be able to reply. This happens even with a continuous successful ping going from one of the wired desktops to the printer at the same time. I can force the printer to reply to wireless clients immediately if I ping it from the AP using the Ping tool from the console. Then, if I wait 60 seconds, I can no longer ping from wireless devices, even with the continuous one still going from the wired desktop. It almost seems like some kind of "tunnel" closes between the wired printers and wireless devices if there is no communication after about 60 seconds or so. Support has remarked that what is happening is very weird, and unexpected. I'm having this exact same issue with multiple printers from different vendors in multiple locations. Our workaround is to have a continuous ping going from our print server at the main office. For some reason, this holds that "tunnel" open between the wireless and wired printers at the remote sites, even though this server is at the main office and is on a totally different VLAN.
