Hello all !
On our multiple link 5 GHz backbone, we have allways experienced a significant speed difference between upstream and downstream - often a factor 2 or more better in direction of the users. We see this on real traffic and also when testing with various techniques. This is too bad, when you have a symetrical internet connection :-(
It is not a resource bottleneck - we have pc's where the load is high.
It is not a routing problem - the problem persists on a bridged network.
N-streme doesn't make a difference.
The link speed (utp) is typically 30-40 Mbps downstream and 12 - 20 Mbps upstream on a 3-hop link
The radio links are good, typically -60 to -70 dB. We do, however, have some interference from our own network, which is quite large with a relatively high number of links. On the other hand, we have been optimizing the links over a long time (years), and everything is in general working good.
Recommendations ???
