Packet Loss with Traffic Spikes?



  • Long time comcast user which have been pulling his hair out because there's been an abnormal amount of T3 and T4 errors.  Over the years, the T4's have disappeared but still plagued with T3's.  I know it's not a pfsense issue but just telling the story so you know that my connection is just OK.

    In any case, I've noticed a small amount of packet loss on the WAN interface on a regular basis.  Within the past 24 hours, I've seen an average of .27% loss and max of 8.6%.  With most of the loss, I've also seen traffic spikes, but not all the time.

    So my question is….is it normal to see packet loss on the WAN (monitoring the gateway address from Comcast) when you're downloading a fairly large file and using up most of the bandwidth?  Should I learn not to worry about it and just move on?

    Thanks!



  • sounds like noise on system t-3 upstream or return noise where t-4 could be in either upstream or downstream

    Argh, I know you're right but I don't want to believe it.  I've been battling with comcast over noise issues for years now….and granted, things are better, but not great.  I thought I would try to rule it out but I guess it really is the noise.
