Greetings to to you. I'm running 4.9-STABLE, and using userland PPP to connect to my ISP. For several months I've been experiencing constant periodic lag in my connection, and it's only recently that I have tracked the problem down to PPP and the LQR feature. I've got 1-mbit ADSL with a static IP. While I have been using FreeBSD for a while, I'm no guru, so please bear with me! Succinctly put: When I enable LQR in my ppp.conf, my connection drops and reconnects every 3 minutes (+/-), since "tun0: LQM: deflink: Too many LQR packets lost". This gives me an annoying 5 to 10 second lag while doing it's thing... possibly fatal while MUD'ing! ;-) An example of a ping series to www.freebsd.org: 64 bytes from 216.136.204.117: icmp_seq=117 ttl=51 time=100.795 ms 64 bytes from 216.136.204.117: icmp_seq=118 ttl=51 time=100.736 ms 64 bytes from 216.136.204.117: icmp_seq=119 ttl=51 time=101.165 ms 64 bytes from 216.136.204.117: icmp_seq=120 ttl=51 time=3728.962 ms 64 bytes from 216.136.204.117: icmp_seq=121 ttl=51 time=2722.021 ms 64 bytes from 216.136.204.117: icmp_seq=122 ttl=51 time=1714.950 ms 64 bytes from 216.136.204.117: icmp_seq=123 ttl=51 time=707.868 ms 64 bytes from 216.136.204.117: icmp_seq=124 ttl=51 time=102.800 ms 64 bytes from 216.136.204.117: icmp_seq=125 ttl=51 time=100.783 ms 64 bytes from 216.136.204.117: icmp_seq=126 ttl=51 time=101.738 ms ... well... you could see how that could get annoying, every 3 minutes. When I disable my LQR, I have a blissfully lag-free connection... but only while it is actually connected. If the line actually drops, it doesn't seem to redial, no matter that I have my ppp set up with -ddial option. If it weren't for the fact that I like to check my email by SSH'ing into the machine, and run Apache for my personal webpage, I'd let it go at that. I haven't included tons of logs or copies of .conf's, since in all my searching I've found a few other people with similar problems, but no real solutions. Basically, am I missing something? Is there no real solution? Do I leave my LQR enabled and live with frequent MUD deaths? Or do I disable the LQR in my ppp.conf and manually restart ppp whenever I get home and notice it's down? Or is there an Option X that I have missed in my google searches? Anybody that can point me in a direction that I've not checked would be appreciated. -Scot
