Of all the hackerboards I tried, the odroid c2 was the fastest and is generally my default target these days. The "chip" is coming along nicely but lacks network. The odroid c1 and rpi2 have been the most reliable. (I'm still looking for a board with a decent toslink port....) ... I just foolishly tried to update my linksys 1200ac, but... it turned out the cable modem behind it was acting up and I lost touch with it (lacking a babel pre-installed)... aha! (/me worms his way through multiple hops through another modem) It looks like my default command line, post install is basically: opkg install luci-ssl luci-app-sqm babeld kmod-sched-cake netperf The 1200ac still has bug https://bugs.lede-project.org/index.php?do=3Ddetails&task_id=3D294&order=3D= status&sort=3Dasc&order2=3Dseverity&sort2=3Ddesc I triggered it with: root@apu2:~/t# flent -H 172.26.64.1 -t 'isitfixed' --te=3Ddownload_streams=3D12 tcp_ndown Warning: Program exited non-zero (1).

I guess it's one way around bugs like this. On Fri, Dec 23, 2016 at 6:51 PM, Aaron Wood wrote: > Excellent. I'll run more tests, and see if I can get some more boxes with > flent installed.
