Bugfixes

• Fixed excessive logging because of app crashes (lldpd) when certain clients are connected.
• Fixed APs going into an Adoption Failed state when the Network Application host (console) IP address changes.
• Fixed false-positive “Multiple devices are using the same IP address” alerts.
• Fixed false positive Association and Authentication failures reported on the Radios > Connectivity page.
• Fixed APs going into an Adoption Failed state after firmware update in rare cases.
• Fixed kernel crashes to improve overall stability.
• Fixed standalone adopted APs sending DNS queries for unifi frequently.
• Fixed UAPs on large sites (with 1K+ clients) causing excessive CPU utilization on Network application consoles/servers.
• [Gen2] Fixed 5GHz SSIDs stop broadcasting in rare cases.
• [Gen2] Fixed incorrect signal reporting in rare cases.
• [Gen2] Fixed 2.4GHz radio broadcasting at 20MHz when configured at 40MHz and the channel is set to Auto.
• [Gen2/Gen3/Gen6] Fixed RF Environment scan 5GHz results not being populated if the scan is initiated during the DFS CAC (e.g. right after the AP boots).
• [Gen4/Gen5] Fixed clients occasionally connecting at low rates/narrower bandwidth than expected.
• [Gen4/U6-Lite] Fixed 2.4GHz radio connection instability in busy environments.
• [Gen4/Gen5] Fixed incorrect AP transmit power shown in WiFiman occasionally.
• [Gen4/Gen5] Fixed channel changes occasionally not being applied correctly.
• [Gen5] Fixed clients connecting at a lower bandwidth (e.g. 20MHz) than the broadcasting radio channel width (e.g. 80MHz) in rare cases.
• [Gen6] Fixed DHCP/connectivity issues at 80MHz, especially with Google clients (Chromecast, Google TV, Pixel phones).
• [Gen6] Fixed connectivity issues with legacy Apple clients (e.g. 2015 MacBooks) when a long ESSID is configured.
• [Gen6] Fixed broken 6GHz client connectivity after changing radio settings (e.g. channel, width, transmit power, etc.).
• [Gen4/U6-Lite] Fixed 5GHz radio occasionally not broadcasting.
• [U6-LR] Fixed incorrect RSSI value for clients when using 160MHz.
