ubus: added reassoc_delay and reason code

2026-05-19T21:52:45Z

Multi Band Operations (MBO) provide stations with additional information about roaming requests. Reassociation delay avoids ping-pong between APs. By default a delay of 30s is requested from the station. MBO code 5 defines signal quality as a reason for roaming. This could be enhanced in the future by responding with other dynamically defined reasons to improve further how transitions are handled by stations. - ubus: add reason code to bss_transition request (actually static only) - ubus: add reassociation delay to let the client know how long it should stay at the new AP dereived from station block timeout. - main: add config option for reassociation delay with 30s as default Signed-off-by: Nils Hendrik Rottgardt

policy: add dynamic signal threshold to band-steering

2026-05-19T21:52:37Z

Avoids ping-pong between bands by adding a dynamic signal threshold. If 5Ghz band is below roaming threshold (e.g. -70) and 2,4Ghz over band-steering threshold (e.g. -50) this adds a dynamic threshold depends on the signal level when station has connected. It adapts to worser signal slowly. This allows to reduce the check interval to lower values like 30s as new standard. - band_steering: added dynamic signal threshold - main: added config option band_steering_signal threshold which specifies the difference until a signal is defined as "better" and band steering is triggered - main: reduced interval to 30000ms to get in use of dynamic threshold more often. It is not neccessary to "wait" anymore to steer a station to a higher band. - usteer: updated default in config Signed-off-by: Nils Hendrik Rottgardt

ubus: DEAUTH reason more accurate

2026-05-19T21:51:50Z

Previous reason codes sent to stations were inaccurate. Respond with correct DEAUTH reason codes in order to give stations better control over their roaming decisions. - policy: correct DEAUTH reason is send to the station - ubus: add reason code to method usteer_ubus_kick_client - usteer: clearly define reason codes as enums Signed-off-by: Nils Hendrik Rottgardt

policy: optimized steering with different levels of aggressiveness

2026-05-19T21:51:11Z

Add some new options and also changed disassociation_timer/_imminent call to have a better roaming experience. This is necessary for some Intel WiFi cards ignoring actual transition request frames due to expecting a combination of disassociation_timer and disassociation_imminent = true. According to posts on the OpenWrt forum this behavior isn't limited to just Intel WiFi cards. Affected stations respond with BSS-TM-RESP status=1 (error) and refuse to roam. - Add new aggr. levels combined with station specific configuration - Set disassociation imminent and timer as default option to have a better roaming by default - Use abridged flag to put priority on neighbors provided - Take care of correct disassociation_timer corresponding to kick_time - Let Disassociation Timer run a countdown before dissassociating the station if roam_kick_delay is longer than validity_period like defined in IEEE. Fix validity_period to 100 beacon intervals. - Add new logging messages (verbose and debug) to visualize the station behaviour Signed-off-by: Nils Hendrik Rottgardt

build: require CMake >= 3.10 due to dropped legacy support

2025-10-04T11:28:46Z

CMake version 4.0 and later require minimum version of 3.5 or later. Update to minimum version 3.10 which is the last not deprecated minimum version. CMake 3.10 was released in November 2017 and is included in Ubuntu 18.04. Signed-off-by: Hauke Mehrtens

ubus: optimize connected_clients output format

- Drop seen / last-connected as the list only contains currently connected clients - Convert past timestamps to relative age - Include current roam-sm state Signed-off-by: David Bauer

policy: don't alter stats when remaining idle

Don't alter roam-sm stats when remaining idle. Previously, a roam-sm-event was registered when keeping the idle-state. Signed-off-by: David Bauer
