Hey

I have implemented a mesh backhaul on 5 Dlink routers with 802.11s mesh protocol and everything work out perfect however the throughput measurements performed with iperf tool indicates much lower throughput (maximum around 18 Mbps) between routers on mesh setup in comparison with that of normal access point client scenario (non mesh setup around 90 Mbps) . can ayone explain this difference?

in the mesh setup when the "iw dev mesh-interface station" is executed the expected throughput is around 26 Mbps but in iperf its around 18Mbps. can anyone also clarify why this is the case and which throughput is the real throughput ?

Any guide and explanation would be greatly appreciated
Thanks in advace
