Hello, I want to bring to people's attention that there is still an outstanding issue with roaming logic defaults. At around -60 to -70 dbi roaming decisions are still taken due to minute disturbances, and at above -50 dbi they are being taken when there is no real need to roam. Current defaults feel to me to be made for non-realistic scenarios. You may have a lot of APs in range with -60 to -70 signal levels, and none of them be particularly better than each other. You find this a lot in office parks. All of them can have some packet loss, but you will not improve user experience by having the roaming happen every few minutes in such cases. Second to that, a minute disturbance like a person passing in front of an AP, or something electrically conductive being put near the antenna may also easily add or subtract few decibels from the signal level quickly. I think there should be at least some moving average used for the roaming decision, or better a more advanced filtering method. Past few patches from Mathew did improve the situation somehow, but I myself is still having issues with overly aggressive roaming every day. Have anybody took a look at this patch https://www.spinics.net/lists/hostap/msg05792.html ?
Maybe if you test this patch and see good results, it will help it get upstream?
