[Cerowrt-devel] linksys 1200ac lockout problem still exists

[Sebastian Moeller]

Hi Dave,

when I use tcp_12down instead of tcp_ndown I end up with something looking sane (see attached image?)

Also:
Summary of tcp_12down test run at 2016-11-20 20:16:54.350770:

                             avg /       median          # data pts
 Ping (ms) ICMP   :        54.08 /        53.75 ms              351
 TCP download avg :         3.52 /         3.57 Mbits/s         301
 TCP download sum :        42.24 /        42.79 Mbits/s         301
 TCP download::1  :         3.50 /         3.63 Mbits/s         301
 TCP download::10 :         3.55 /         3.61 Mbits/s         301
 TCP download::11 :         3.57 /         3.62 Mbits/s         301
 TCP download::12 :         3.54 /         3.66 Mbits/s         300
 TCP download::2  :         3.51 /         3.61 Mbits/s         300
 TCP download::3  :         3.55 /         3.61 Mbits/s         301
 TCP download::4  :         3.59 /         3.67 Mbits/s         300
 TCP download::5  :         3.46 /         3.55 Mbits/s         300
 TCP download::6  :         3.49 /         3.60 Mbits/s         301
 TCP download::7  :         3.50 /         3.59 Mbits/s         300
 TCP download::8  :         3.48 /         3.57 Mbits/s         301
 TCP download::9  :         3.50 /         3.58 Mbits/s         300


looks fine. But maybe tcp_12down is not exactly doing the same as tcp_ndown… I tested from a laptop attached to one of the omnia’s lan ports (omnia’s wan is connected to the lan port of a LEDE r2222 wndr3700v2 with double NAT).

Best Regards
	Sebastian
