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

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

main: disable probe steering by default

2022-06-28T00:27:20Z

As probe steering only makes sense in specific deployments, it should be disabled by default. Update the example config to reflect this change. Signed-off-by: Stijn Tintel Acked-by: David Bauer

usteer: add option for probe steering

2022-06-28T00:27:13Z

Probe suppression is mostly useful in high density deployments, where all APs responding to all client probes would result in all channels being saturated. It effectively hides APs from clients, and can cause problems in normal density deployments. Add an option for it, so it can be disabled. Signed-off-by: Stijn Tintel Acked-by: David Bauer

main: disable load balancing by default

2022-06-28T00:27:02Z

As load-balancing only makes sense in specific deployments, it should be disabled by default. Update the example config to reflect this change. Signed-off-by: Stijn Tintel Acked-by: David Bauer

local-node: periodically send link-measurement requests

2022-04-04T15:08:07Z

Send link-measurement requests to every supporting local-sta in order to acquire information to assess the link-quality bi-directional. The link-measurement request is sent each configurable interval. It can be disabled by configuring the interval to 0. Signed-off-by: David Bauer

band-steering: add band-steering component

2022-03-18T20:46:29Z

This adds a new band-steering component to usteer. With band-steering enabled, usteer will attempt to move clients with a consistently good SNR / signal from 2.4 GHz to the 5 GHz band. In contrast to existing policies usteer tracks, band-steering is non-invasive and will not lead to forceful connection termination. Signed-off-by: David Bauer

policy: add steer-reject-timeout

2022-03-18T20:46:29Z

Add a timeout in case a STA rejected a transition request. For this configurable timeframe, usteer will refrain from steering the client another time. Signed-off-by: David Bauer

add local_mode config option

2022-03-17T09:05:56Z

This prevents communication with other usteer nodes and allows it to be used for purely local band steering / load balancing Signed-off-by: Felix Fietkau
