The netperf server is running on a machine which sits on my 192.168.11.x network. I've been testing things by connecting up the DUT WAN to that network and then using 192.168.1.x (or 172.30.42.x) as the DUT LAN side. My wireless network is bridged to 192.168.11.x.. Yes, Yes, I know this is bad but I haven't put in the time to figure out how to configure things such that all the broadcast stuff like printers and chromecast Just Work in a routed world. The SO gets unhappy with me when they are broken and it's difficult to explain the reasoning. It's on the TODO. network-manager automatically connects wlan0 to that network. When I plug up the ethernet cable network-manager sets up eth0 as the default route but, doesn't shutdown existing wlan0 connections. So talking to the DUT via ssh or http: works as expected. However, when I run: netperf-wrapper -H server -l 15 --disable-log -p all rrul If I forgot to turn off WiFi then I'm completely bypassing the DUT and testing my WiFi network instead. "This is not the network you are looking for." Sigh. Sorry for all the noise. Thanks for everyones help. Now I'll get back to the original task of comparing the performance of the 1900acs factory firmware vs openwrt trunk with sqm. -- Richard A. Smith
