However, I started seeing some unstable connections between the WiFi router and FreeBSD. I was on FreeBSD 12.0-RELEASE and switched to 12.1-RELEASE. Both versions have same symptoms. I get "dhclient: send_packet: No buffer space available" to console and then I frequently lose connection after seeing it. After taking the wlan down and re-connect it with wpa_supplicant, I usually get a connection back. On the side note, I also see these outputs to console and syslog: ath0: bb hang detected (0x4), resetting ath0: ath_legacy_rx_tasklet: sc_inreset_cnt > 0; skipping Does anyone have any advice how to fix/work-around or where to start looking: ath driver, dhclinet, kernel, wlan, and/or wpa_supplicant? Thanks, Hiro
