Hi. I have the same problem with the Ethernet port on the station side of B5C link. Every three days or so the ethernet port stops flowing the traffic, although the led is on and disconnecting the antenna from the switch doesn´t solve the problem. I connect my laptop directly to the PoE and can´t ping the machine. It lasts for several reboots and hours and eventually at the 12th reboot the NIC starts working, but the ping command shows a lot of timeouts. Never found this issue in any other manufacturer and the guys from mimosa are a call center not a support center, as they aren´t field engineers and if so many installers reported this problem i don´t understand why the guys from mimosa are playing dead about this issue. Usually the focus is on a proper earthing, but proper earthing only solves problems of RF and i would like someone tell me how to make a proper earth in a sandy beach??? Yes, because if the remote location is a sandy beach is not possible to use mimosa products??? So, in reality they don´t know what´s happening and then they stay muted about this issue. Conclusion: throw the units to the sea and buy Alvarion or Engenius that never ever give any problem at all.
P.S. one thing i have to remark, never had problems with the link itself, always in the air, moving channel when needed, although with lots of fluctuations on several air parameters. But 99% isn´t enough, we need 100%, as if the NIC doesn´t work, there are no traffic flowing, is the same as a wall in the end of the highway. So, guys from mimosa, wake up and at least have the decency to answer properly to those guys that give you the money to go on and as if you may perceive not for long.
