Update: newest firmware 1.0.03.15 - same issue persist! I have around ~1000 entries every 4~6 minutes. I have email settings to send over logs when 1000 entries are reached. Emails are coming through ever 4~6 minutes. Wifi only ever reaches max85% of my broadband speed. Compared to separately connected access Point via ethernet to the same router i get 97-99% of broadband speed. Router settings are bare minimum without any antivirus or web/Mac filtering. Only SSID&passw & local IP range is defined. All other settings are as per factory resrt which i have done during firmware upgrade. Please escalate this issue. Kindly K. ... View more

Workaround found - disable 5Gz wifi.  this allows client to connect to wifi on 2.4Gz .  seems that 5Gz connectivity is faulty and clients connections "freeze" on 5Gz without any throughput.     above workaround - still it dos not resolve log entries like these, which appear almost every second.: warning kern kernel: [3114778.726982] ampdu_dbg: again2 ifsstat 0xaf nav_stat 0x0 2019-May-01, 09:28:50 UTC warning kern kernel: [3114778.726974] ampdu_dbg: again1 ifsstat 0xaf nav_stat 0x0 2019-May-01, 09:28:50 UTC warning kern kernel: [3114778.726966] ampdu_dbg: cwcur0-3 f f 7 3 bslots cur/0-3 7 0 0 0 0 ifs_boff 0 2019-May-01, 09:28:50 UTC warning kern kernel: [3114778.726928] ampdu_dbg: txall 222 txbcn 0 txrts 0 rxcts 0 rsptmout 0 rxstrt 0 2019-May-01, 09:28:50 UTC warning kern kernel: [3114778.726921] ampdu_dbg: pktpend: 0 0 0 0 0 ap 1 2019-May-01, 09:28:50 UTC warning kern kernel: [3114778.726914] ampdu_dbg: ifsstat 0xaf nav_stat 0x0 txop 83395 2019-May-01, 09:28:50 UTC warning kern kernel: [3114778.726904] ampdu_dbg: wl0.0 dead_cnt 2 tx_in_transit 1 fifordy 0x0 frmcnt 0x400 fifosel 0x7 2019-May-01, 09:28:50 UTC warning kern kernel: [3114778.726882] ampdu_dbg: wl0.0 1c:36:bb:85:d2:04 scb:bdbd8000 tid:0 2019-May-01, 09:27:45 UTC warning kern kernel: [3114714.056909] ampdu_dbg: again2 ifsstat 0xaf nav_stat 0x0 ...
