Hi, Did some tcpbench testing and got following results: Each test run with: tcpbench -s || tcpbench -t 15 <host> commands. Host AP: apu 2b4 with athn, client = thinkpad t430s with iwn (OpenBSD) channel 9 running old snapshot etc: 11n client -> server ~4, server -> ~0, 11g client -> server ~16, server -> client ~0-6mbs --- updated to new snapshot: OpenBSD 6.0-current (GENERIC.MP) #206: Sat Mar 4 09:22:00 MST 2017 = added another antenna, moved the ap to better spot, switched old ap off, changed channel to 11 11n client -> server: ~6mbps, server -> client ~0.2mbps 11g client -> server: ~7mbps, server -> client ~3mbps --- switch to channel 3: 11n client -> server: ~7mbps, server -> client: ~0-5mbps 11g client -> server: 16mbps, server -> client: ~5mbps --- applied dyn rts patch: 11n client -> server: 4-7mbps, server -> client 0.2-5.5mbps 11g client -> server: ~4mbps, server -> client: ~5.5mbps At least what pops up in the measurements is that 11g gives more stable behaviour. 11n speed seems to vary a lot in that 15s test compared to 11g.
