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. | |

| Re: Small packets ok... sustained lost. 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.... | |
