I've got one device on my network that randomly, and suddenly, loses its connection to the internet. Full stack Meraki; wired and wireless interfaces are affected.   The short term fix is to change the DNS from the Meraki DHCP assigned address to something else.   Device is an iMac 24" M1, running 12.3, but the problem has been around since release of the iMac when it was running previous OSes.   When it fails, WiFi only devices, such as an iPad, continue to work.   This means it only affects the one wired device on the network - the other wireless users either never notice it or never complain - and that includes just one portable device and a few TV's. And the TV's are ALWAYS on, so it seems to be just affecting the iMac.   It is completely random - there is no way to do a packet capture when it happens - but it happens 1-3 times per month.   Any ideas on tracking this down? ...

Need some help trying to fix Smart/streaming TV's pixelating. TV's are Samsung "The Frame" if it matters.   Area / location might be important to this: Old Town, Alexandria, VA. Old homes & buildings (some of them hundreds of years). Property records say the home was built in 1978, but I'm not sure how true this is - could have been 2 houses put together as is common for larger homes in the area. Slightly less than 3 miles from the tip of Washington Reagan Airport, but out of the actual flight path by about 2/3 mile.   Network is wireless only, 3 x MR36. Second floor device is the wired one.   Basic Indoor Profile has been edited to allow for band steering, minimum bitrate on 2.4GHz is 24, and minimum bitrate on 5GHz is 12           TV 1   TV 2   TV 3   ...

I've got a couple of these lights on my network:https://www.elgato.com/en/key-light-air   They are controlled by software on the computer; there is no way to interact with the lights directly.   Once the lights are added to the network, they almost completely disappear - the software sees them, and can control them, less than 5% of the time (in my experience).   the lights are shown on the dashboard, and there is good signal to both.   But since the Elgato Control Center software cannot interact with the lights, I can't turn them on or off, short of unplugging them.   Elgato's support has been terrible. They blame the computer (but the software doesn't find the lights on the phone, the tablet, or any other computing device. They blame the network, which I can understand, but my network consists of one vlan and a couple of SSID's, all of which are able to communicate with each other. The computer, phone, tablet, and lights are all on the same SSID.   Now elgato support is asking if multicast is enabled over wifi. It looks to me to be enabled by default (https://documentation.meraki.com/MR/Other_Topics/Multicast-Unicast_Conversion), but what do I know?   Has anyone experienced this? Anyone know of a way out of this mess? ... View more

I've got a bunch of Sonos equipment in my house, and just added some WiFi only Moves.   I also have a secure and IOT wifi networks; all of the Sonos and other junk connect to the IOT side of things.   The trouble I was seeing was I could play to the house except for the moves, or I could play to one Move - at a time. If I started the music streaming on a Move, I couldn't add the other, and if I started in the house, I couldn't add the Move. It just wouldn't play. It would appear to be part of the group, but no noise would come out.   In talking to Sonos support, they had me adjust the rule (boxed in red) at the bottom of the screen shot - allow any any to the local lan. and that fixes things. But it kind of defeats the purpose of a separate IOT network, doesn't it?   So I went searching for the ports that the Sonos products use, and that resulted in the rules (boxed in green) to see if things would work. When I disabled the red rule, problem returned; nothing in the green boxes fixes anything (I first tried destination 192.168.128.0/24 before trying Any) makes it work.    Is there any rule I can insert that will give me peace of mind and let me still play all the Sonos devices together?     ...

I've got a situation I can't figure out.   I've got a network with quite a few IOT devices, including some Apple TV's and some Printers.   On the primary network, I need to be able to get to the Apple TV's and the Printers.   How can I configure the network to allow this? ... View more

I'm running the beta firmware, and supposedly this feature has been enabled for me.   I can't find any documentation what to enter in the various fields in the MR Client VPN or Site-to-site VPN settings, nor do I understand what to enter in the MDM profile I'm setting up. ... View more

I'm trying to only allow certain countries, but some things are getting blocked that shouldn't be.   For example, today I was trying to do an Apple iCloud password reset, and even though I was allowing the US, Canada, and most of western Europe, it still wouldn't work until I removed the rule.   Is there a way, in the logging, to detect what or where the block occurred? I did a visual traceroute, and it didn't seem to route through any non-allowed countries. In the syslog server, what search would I set up to know when a blocking rule was enforced? ... View more
