hello all.
I am running 19.7.7 on some alix2d2 boards. Each has two ath9k dual band cards, 256mb of memory & a 4GIG cf-card.
I am using these as mobile client devices on a large campus style network. (hundreds of AP's in a classic honeycomb setup) The problem I am running into is that the device seems to wait until the signal has dropped before it roams. not always, but enough to be very annoying. sometimes when it has dropped off, it seems to hang waiting for a connection. (anywhere from 10secs ~ 1 minute). when I check the logs after a hang, it looks like the wpa_supplicant is blacklisting the closest AP after a couple failed association attempts. (i would like to disable this behavior if possible.)
I came across a similar post that is now locked: Client roaming not working (Router in sta mode)
What have I tried:
- Removing wpad-mini in favor of full wpad
- Enabling bgscan in the wireless config. (this didn't do anything as far as i can tell)
- Enabling bgscan through hostapd.sh (in and outside of the network block)
- it seems like the wpa_supplicant build file in 19.7.7 has bgscan enabled.(https://github.com/openwrt/openwrt/blob/openwrt-19.07/package/network/services/hostapd/files/wpa_supplicant-full.config)
- Setting bgscan in the wpa_cli (get a "ok", but no signs of scanning or roaming in the logs.)
As opposed to the linked question, as far as i can tell the full wpad for 19.7.7 on github has the options enabled for build-time. unless I am just missing something really simple to get this to work...
How do I tell in the logs when it is actually working? (I am assuming some sort of CTRL-EVENT should be showing up in the logs) or maybe need to set a higher logging verbosity?
If anyone can shed some light on this subject it would be greatly appreciated.
P.S i have no problem custom building firmware or modifying binaries to get this to work, just not sure where or how to proceed at this point.
Thanks in advance!
