In my (over) 10 km p2p wireless link I have Lobo 912s from Lobometrics Wireless ( http://www.lobometrics.com) obtaining almost 30 Mbps (not bad for 600 US$) with its channel bonding feature, but when I use WDS the performance degrades to a little bit over 19 Mbps. I ordered from Lobometrics because they guarantee they are WiMAX updatable which should give me better performance, but, untill then, I am using WDS.

Is it normal for WDS to hit the throughput ?
