My experience is the list seems to have better info on these odd issues. One side of this link requires snow shoes to get to so I am trying to avoid replacement if at all possible.

Several times a day now it stops passing most traffic. It can be humming along at 25mbps down and 5mbps upload and then drop down to 2mbps download and less than 1mbps upload. Downlink RSSI -65 dBm Downlink SRN 30 dB Uplink MCS MCS 14 Downlink MCS MCS15 All remains constant during this time. The ping falls apart during this time between the AP and the SM although pings through the network to the SM or through the network from the AM are both fine it’s just between them that starts to drop packets. The units show heavy retransmission packets from the moment the link is brought online around 40% at times. At this point I would assume noise is the issue. But here is the odd part I would like some help with. Rebooting the link fixes the issue but leaving the link alone does not. It will stay “broken” until one or both sides of the link are rebooted. Then it works perfectly for a time and falls apart again. Current firmware is 3.5.1 but we have run it on 2.6.1.1 and 3.3 with similar results. Any thoughts on how to troubleshot this one would be awesome. Best Regards. Brandon Yuchasz -- -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
