Hi,
Tried 4 different boxes. 2 in live environment and 2 in lab. I can conclude that running Nstreme/Nstreme-Dual the routers stops forwarding traffic every 10 seconds or so when under heavy load, pauses 3-6 seconds and then starts again. I have just used normal Bandwith tests through the wireless 5GHz links. (WDS & Dual Nstreme). Disabling Nstreme everything is stable.
Good news though, had a serious problem with a link that gave me too much SNR.. Somehow B6 manages to get traffic through this link.. Great!...
