THe AP is a big Cisco one, more I cannot see, with 3 antenna. For the NIC, what do you want to know: wlan0 IEEE 802.11abgn ESSID:"XXXXXXXXXX" Mode:Managed Frequency:2.412 GHz Access Point: 00:24:C4:AB:BD:E0 Bit Rate=72.2 Mb/s Tx-Power=15 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=51/70 Signal level=-59 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:685 Invalid misc:59 Missed beacon:0 The last line looks interesting, excessive retires: 685, INvalid misc: 59 Note that the "Tx excessive retries" increase steaadily and radically, downloading updates with aptitude I see afterwards: Tx excessive retries:17922 The "Invalid misc" also increase, but slowly.
