Hey all, hoping someone can help me unravel a puzzling Meraki wireless performance issue. We're seeing surprisingly slow download speeds, consistently under 60 Mbps, during peak hours (9 am-5 pm) when connected to our MR44 and MR56 access points. This is happening despite a seemingly robust network backbone: our Meraki MX250 firewall uplinks to an MS355 core switch at 5 Gbps, and the MR44/MR56 APs are connected to the MS355 via 10 Gbps ports, with verified 5G/full duplex uplinks from the APs themselves. We have a total of 15 MR44s and 4 MR56s. My client, MacBook Air M2, confirms it's on the 5 GHz band (with the MR56 set to 80 MHz), and band steering is enabled. We're running three SSIDs (IoT, BYOD, Business). In our most congested areas, we see about 20-30 clients per AP. What's really throwing me off is that speeds significantly improve after 6 pm, suggesting a load-related problem, but I can't pinpoint the bottleneck. I've already checked the Meraki dashboard to confirm 5 GHz connectivity, used Fast.com for speed tests, tried multiple APs and client devices, verified no client limits or throttling, and even disabled some content filtering on the MX250 to rule that out. I recently upgraded from an MX85 to an MX250 and added two MS355 switches specifically to improve uplink speeds to the APs, so I'm scratching my head as to why we're not seeing the expected performance. What should I be looking at to get these wireless speeds where they should be? Any suggestions or diagnostic steps would be hugely appreciated! TLDR; We just upgraded from 1Gb to 5Gb; MX85 to MX250; added 2 MS355 48-port and are still receiving the same slow speeds.
