When the devices power on, the main LED will be amber in color. Additional LED statuses are described below. LED Status Meaning Solid Green AP is communicating with the Meraki dashboard and is functioning properly Solid Blue AP is communicating with the Meraki dashboard and currently has clients connected Blinking Blue AP is applying the latest configured firmware Cycling Colors AP is booting and attempting to reach out to the Meraki dashboard AP is going through initial boot up process, is having trouble communicating to the Meraki dashboard, or has a Amber potential hardware issue Blinking Amber AP has determined there is a hardware fault 6 Common Troubleshooting My device is connected to the network but not checking in to the Meraki cloud or shows a solid orange LED Confirm that the device is powered on and has a valid IP address that is able to access the internet. Use the local status page to get more information about the connectivity status of the device such as if it can successfully reach the local gateway, internet, and/or Meraki cloud servers. If necessary, contact Meraki support for additional assistance. My status LED is blinking BLUE A blinking BLUE Status LED indicates that the device is in contact with the Meraki cloud servers and is performing a firmware update. This can sometimes take 20-45 minutes or more to complete depending on hardware and other factors. My status LED is blinking ORANGE The device is not able to successfully communicate with the Dashboard Cloud servers or there may be a hardware issue with the device. Check the local status page of the device to confirm the status. If necessary, contact Meraki support for additional assistance. Event Log The most common event log messages and their meanings are listed in the Common Wireless Event Log Messages guide. Common Wireless Alerts 802.1X authentication failure Indication that the access point was not able to appropriately communicate with the configured RADIUS server and thus is unable to authenticate clients on an SSID that requires users to authenticate via RADIUS credentials. DFS Event When the access point detects a radar signal on the same channel it is broadcasting on with its 5 GHz radio, the access point will then take action so it will not interfere with the radar single. There are several steps the AP will take when a DFS event takes place. First, all new transmissions on the channel will be blocked, followed by a broadcast of an 802.11h channel-switch announcement. The access point will then disassociate all remaining clients, and then select a new 5 GHz channel to broadcast on. FAQ Are MR45 & MR55 compliant with the Wi-Fi 6/802.11ax standard? As of April 29th, 2019 the 802.11ax standard has not been fully ratified. This is expected to be completed at the end of 2019. MR45 and MR55 comply with a majority of features that are part of the 802.11ax standard and end-users can immediately recognize all of the benefits related to these features. Does Meraki have Wi-Fi 6 APs with external antennas? Are those on the roadmap? MR45 and MR55 do not come with external antennas. The new Wi-Fi 6 standard does enable up to a maximum 4x increase in speeds at the cell boundary. Meraki does intend to build Wi-Fi 6 APs with external antennas, but as of April 29th, 2019 we have not announced anything to the public. Do MR45 & MR55 have UL-MIMO and UL-OFDMA? 7 Today, MR45 and MR55 support DL-MIMO, and DL-OFDMA, not UL-MIMO and UL-OFDMA. Meraki has observed that a majority of bandwidth in wireless networks is downlink traffic, and a majority of the impact on aggregate throughputs comes from downlink traffic. How will Meraki’s new MR45/55 work with existing legacy Wi-Fi networks? MR45/55 are backward compatible and will work with legacy devices. Additionally, there are very few Wi-Fi 6 capable devices available in the market and hence a majority of the traffic seen on the APs will be from legacy devices. What is the benefit of Wi-Fi 6 AP’s if there are no Wi-Fi 6 clients on the network? With the MR55 you now have an 8x8 access point that enables more streams to the client. This will enable better access point range and enable more spatial diversity which enables better MU-MIMO performance. Additionally, legacy Wi-Fi clients will benefit from the new 4x4 2.4 GHz radio, this doubles the number of spatial streams available to clients in this band for both the MR45 and MR55. As of early 2019, there have already been several Wi-Fi 6 clients released, and more are expected through 2019 & 2020. What improved performance can I expect on my network? Wi-Fi 6 introduces a host of new features that can help improve range, aggregate throughput, power savings, and more. Features such as OFDMA, MU-MIMO, 1024 QAM, BSS coloring all work to provide the next generation of Wi-Fi, targeted at the modern world of high-density client counts, and throughputs. The exact improved performance will depend on the particular nature of the network. Is an mGig switch required for MR45/55? It is not required for the network, but MR45 and MR55 will have mGig support. Whether the switches are needed depends on the specific network and the bandwidth that traverses the AP. As more Wi-Fi 6 clients become available, it is likely that you will need mGig support. Does MR45 & MR55 support Low power mode? No, it requires 802.3at power and do not guarantee the functioning or performance when they are powered with 802.3af power. How does Wi-Fi 6 work or compete with 5G? Wi-Fi 6 and 5G networks are expected to work together. In fact, several Wi-Fi 6 technologies, including OFDMA are analogous to cellular LTE technologies. We expect that Wi-Fi 6 will continue to be the dominant access technology indoors, while 5G will see increased use in outdoor environments. Wi-Fi 6 and 5G are expected to have more seamless transitions between the two technologies. When higher speed 4G was introduced, Wi-Fi offloading increased, and 5G is expected to have a similar impact. According to the Cisco 2019 VNI, 71% of 5G traffic is expected to be offloaded to Wi-Fi or small-cell.
