Hi @Timc95, thank you for sharing this question with the community 😊 People are having some fun with the analogies, but all joking aside, you have gotten some good answers here.    There is a fun blog post from Cisco that, while older (published in 2018), is still relevant and covers this very topic! Read the Layers of Security blog post here. ... View more

SD-WAN is the easiest to implement since you are not doing any NAT sessions over 2 providers but are just tunneling traffic between your branches.  So after the security check your MX only needs to route the packets. SD-Internet is more complex since that deals with traffic being sent to the internet directly from your MX.  This means if you suddenly change from WAN1 to WAN2 due to conditions all existing sessions are now NAT'ed with a different WAN IP and usually cannot go on in the case of TCP and have to be reestablished. ...

Just one other thought, reading this again. MG is not involved in setting up secure tunnels between locations - if that's what you need.   That would be an MX (or a vMX) to do that.   For best functionality you'd have an MX (or a vMX) at the other end too, but it could in principle be IPSec device;   either another vendor's device, a compliant cloud service (SSE / SASE) or an MX / vMX that resides in a different Dashboard Organization. ...

Hi Timc95,   In addition to the alemabrahao comment, please find the following documentations: Common sources of wireless interference Checking Signal Strength and Throughput on a Cisco Meraki Wireless network Troubleshooting poor wireless performance     SNR = Signal Level (dB) - Noise Level (dB). For example, if a signal is -50 dBm and the noise floor is -90 dBm, the SNR would be 40 dB (-50 - (-90) = 40). A higher SNR value means the signal is stronger in relation to the noise     Why higher SNR is better: A higher SNR leads to fewer errors in data transmission, resulting in faster and more reliable connections.  A strong signal relative to noise means the receiver can more easily distinguish the intended signal from interference, leading to better performance.    SNR in Wireless Networks: In wireless networks, SNR is a crucial factor in determining the quality of a connection.  A low SNR can lead to dropped connections, slow speeds, and overall poor performance.  Factors that can affect SNR include distance from the access point, interference from other devices, and the quality of the wireless channel.   In conclusion, in general, a signal with an SNR value of 20 dB or more is recommended for data networks where as an SNR value of 25 dB or more is recommended for networks that use voice applications.
