"Tranzeo informed me yesterday that they will not support Mikrotik related problems."
HA! This is funny because back in the Tranzeo/MT disconnect days of last summer wasn't the problem traced to Tranzeo firmware not following 802.11 spec? And tranzeo still wouldn't fix it so Mikrotik jumped in and saved us all from Tranzeo's problem.... After this is all said and done who would ever want to deploy Tranzeo 3.65Ghz gear when they can't even get the simple 802.11 stuff right! Kurt Fankhauser WAVELINC P.O.

Dropping you an off-list response with much more detail. But also posting here to report that we are seeing a very similar problem. We are seeing the Tranzeo units fail to sustain downloads after two to five minutes when they are in router mode performing NAT. Tranzeo is blaming Mikrotik. However, we have been able to prove that the failure is unique to the Tranzeo unit. Our solution is the same as yours. Do not use the Tranzeo in router mode. Put it in bridge mod and all is well. We have tested non-Tranzeo radios in router mode and there is no problem. We are finding that the problem exists for both firmware versions 3.6.7 and 4.0.2. We are not seeing any problems with the connections or the pings when the downloads fail. It seems to be a time related issue rather than related to the amount of data moved. Download failure occurs 100% of the time when the Tranzeo is in routed mode. Downloading the same file from the same source when the Tranzeo is in bridge never fails. Download failures always occur within 2 to 5 minutes and are not dependent on the mode of file transfer. Tranzeo informed me yesterday that they will not support Mikrotik related problems. -- Steve Smith, Chase 3000, PO Box 760, 554 Kramer St., Imperial, NE 69033, 308 882 3000 office, 308 883 3001 cell Kurt Fankhauser wrote: > All was running fine on our CPE's running version 3.6.7 and did the upgrade > to version 4.0.2.
