Hello, thank you very much for your support. With your explanation I found the causer. It is my WiFi Repeater (Fritz!Wlan Repeater 1160). If I connecting directly to my AP, the connection works fine and "netstat -W iwn" is not eye-catching. I tried to fix it with resetting the Repeater. I also choosed a less used channel. Indeed the repeater still trying to death auth me:
ieee80211 on iwn0: 0 input packets with bad version 4 input packets too short 0 input packets from wrong bssid 39 input packet duplicates discarded 0 input packets with wrong direction 9 input multicast echo packets discarded 0 input packets from unassociated station discarded 0 input encrypted packets without wep/wpa config discarded 0 input unencrypted packets with wep/wpa config discarded 14 input wep/wpa packets processing failed 0 input packet decapsulations failed 0 input management packets discarded 0 input control packets discarded 0 input packets with truncated rate set 0 input packets with missing elements 0 input packets with elements too big 0 input packets with elements too small 0 input packets with invalid channel 130 input packets with mismatched channel 0 node allocations failed 0 input packets with mismatched ssid 0 input packets with unsupported auth algorithm 0 input authentications failed 0 input associations from wrong bssid 0 input associations without authentication 0 input associations with mismatched capabilities 0 input associations without matching rates 0 input associations with bad rsn ie 211 input deauthentication packets 0 input disassociation packets 0 input packets with unknown subtype 0 input packets failed for lack of mbufs 0 input decryptions failed on crc 0 input ahdemo management packets discarded 0 input packets with bad auth request 10 input eapol-key packets 0 input eapol-key packets with bad mic 0 input eapol-key packets replayed 0 input packets with bad tkip mic 0 input tkip mic failure notifications 0 input packets on unauthenticated port 0 output packets failed for lack of mbufs 0 output packets failed for no nodes 0 output packets of unknown management type 9 output packets on unauthenticated port 1 active scan started 0 passive scans started 0 nodes timed out 0 failures with no memory for crypto ctx 0 ccmp decryption errors 0 ccmp replayed frames 0 cmac icv errors 0 cmac replayed frames 0 tkip icv errors 0 tkip replays 0 pbac errors 0 HT negotiation failures because peer does not support MCS 0-7 0 HT negotiation failures because we do not support basic MCS set 0 HT negotiation failures because peer uses bad crypto 0 HT protection changes 8 new input block ack agreements 4 new output block ack agreements 178 input frames below block ack window start 0 input frames above block ack window end 0 input block ack window slides 0 input block ack window jumps 56 duplicate input block ack frames 0 expected input block ack frames never arrived 0 input block ack window gaps timed out 0 input block ack agreements timed out 0 output block ack agreements timed out Can you say me if this is a problem of the shitty repeater. So I will throw it away and maybe make my own or buy a better one. Or is it a bug of OpenBSD which maybe fixed in a newer version? So I would wait. Thank you very much! greetings, Peter
