Speed falling from 90Mbps to 30Mbps

I have a PTP made with 2 LHG 60G. I can´t get more than 30Mbps from it. The thing is that when doing a Btest between both antennas, it starts giving 90Mbps, but after 10-15 seconds, it falls to 30Mbps. Also in a Btest between RBs behind antennas in each side.

The equipment used is as follows: RB3011 - LHG 60G - LHG 60G - CCR 1016

Any suggestion would be appreciated. Thanks.

Any queues on rb3011 ?

Exactly, but the queues were on the CCR 1016, a queue tree afecting all downloads on a bridge. Feeling a bit dumb now. Thank you so much Zacarias! :slight_smile:

You are welcome… it was a bit obvious from the diagram…
