wifi roaming
by chrisliu from LinuxQuestions.org on (#6J9AT)
Now I am working wifi roaming, using standard 80211mac and user space wpa_supplicant.
I want to achieve this:
when current associated RSSI is below threshold, then automatically roam to new best RSSI AP
I am not sure currently mac80211 support this.
(1) how to set this RSSI threshold
(2) my assumption to achieve this, there are 2 approach.
A: wpa_supplicant with background scanning, I test this, but the performance is not so good, when roam to new AP, scan takes around 140ms per channel, I check the mac80211/scan, it seems using passive scanning, how to change to active scanning? If so, I am assuming it will decease scanning time.
B: is it possible for mac80211/ath10k driver, when associated RSSI below threshold, it automatically roams to new best RSSI ap, no need user space wpa_supplicant involved. I think user space wpa_supplicant doesn't have neighbor information, while mac80211 should have.
