[Discuss] Annoying network problem

[lconrad at laymusic.org (Laura Conrad)]

I have an intermittent but quite frequent problem with my network.
Symptoms include:

         Backups via deja-dup to google drive which are supposed to take
         place nightly, a couple of times a week don't finish.

         When I come back to my computer after an absense of hours, the
         tabs in my browsers need to be reloaded (e.g. amazon.com).

         The most annoying is that when I tell my mail reader (gnus) to get my
         mail, it hangs.

I'm quite sure this is comcast's fault, because when I visit my friends
in Arlington, I had this problem when they were on comcast but when they
switched to RCN it stopped happening.  Switching to RCN is not an option
either in Cambridge, where I live, or in Fall River, where I'm currently
a homeless refugee because of a fire.

I believe this output demonstrates the problem:

I would guess that that node that's losing 100% of the packets isn't
supposed to do that.  Does anyone know a way to convince comcast to look
at the problem and fix or work around it?

Thanks,

...bonemeal was in such high demand that the remains of soldiers at
Waterloo and other major battles were sold, ground, and resold, mostly
to England.
