Re: Small packets ok... sustained lost.
said by lutful  :But please remember that exact same antenna and cable is receiving without any error. There was anecdotal evidence posted recently where the weaker Rx signal passed through bad coax fine but the stronger Tx was getting discombobulated. It is a theoretical possibility. |

It is a theoretical possibility. I recall such a conjecture put forward by John Galt in response djhurt during the summer months. Unfortunately the cable was discarded before any tests could be done.
Since then I have collected, tested and posted photos of some visibly damaged cables that amazingly still work.
I can say confidently that if the RF signal path is damaged in such a way that 1W signal is "shorted to ground" at certain points during common modulation schemes, the same scenario will occur so many times during a single packet transmission that no packet could be transmitted without error.
But this Cisco transmitted and recieved thousands of packet successfully, so there is something else going on. |

US | I believe it was Stealthwave who was having the issue with the coax this past summer. I recall a thread and talking to him about that. |

| Is it possible that You have a radio somewhere on the network that has an ARP table that is screwed up?. I have a pair of Tranzeos(5A-24)that I am using for a backhaul link, and every time I added a customer, I had to reboot the master unit so the ARP table would flush and allow the new CPE to talk to the core router. Is there a way in Cisco AP's to mess with this setting?.

Is there a way in Cisco AP's to mess with this setting?. I thought of that too, but rebooting all APs and backhaul bridges doesn't seem to help. I have not been able to find anything on the Cisco APs/bridges to clear ARP. Just reboot.
*Tranzeo Sidenote* I have installed (since the windstorm previously mentioned) a pair of Tranzeo TR6-5a bridges as the backhaul on this tower because of problems with the older Cisco bridges after the storm. I know that the ARP table on these gets buggered up when I use my laptop out in the field and then in the office. I have to reset the bridge from another computer before I can access the APs from my laptop.... |
