[gentoo-user] Internet slow at times. Can't figure out why. ISP??

[Dale]

Hey,

As some may recall I bought a new router and modem.  I was sort of
hoping one or both of those would solve a issue I've noticed for a good
long while.  At times, my internet gets really slow, slower than it
should be at least.  I have DSL and it isn't to fast to begin with.  At
times tho, I'm only getting about 20 or 30% of what I should.  This is
what the modem shows for speed:


Downstream Rate     1536 Kbps
Upstream Rate     384 Kbps


Don't laugh OK.  I live in the sticks and for many years, I was lucky to
get 26K down on dial-up.  I hoping for faster one day but this is better
than dial-up, mostly.  ;-) 

Here's some info.  This slow down seems to always happen in the
evenings, somewhere between 6 and 9PM.  Generally, the rest of the time
it is pretty close to its max speed.  Because it works most of the time,
I'm thinking this is not hardware or cable related.  I'd think it more
consistently slow if it was.  That said, it does the same with any
modem, any router or any sets of cables.  I even bought some bulk cable
and ends then made my own cables and tested them with a ohm meter to be
sure they were really good.  No improvement.  I also disabled the
wireless on my cell phone to be sure it wasn't doing something funny. It
is set to download only when I tell it but there is one google thing
that ignores that. 

The only things I see is in the logs.  Here is some of the log from the
modem, currently the Netgear 7550.

I googled but didn't really find anything, good or bad, about those
entries. This is from the router, the TP-Link I bought a few months ago.

I'm only copying a small portion of it because it is very repetitive.
It's pretty much the same thing over and over again. I'm not thinking
those are errors tho. The router sure does send recv DHCP stuff often tho.

Does anyone see anything that is a problem here? I'm thinking my ISP is
just overloaded and throttling the connection. I've swapped hardware and
cables to the point that I don't see how it could be that. Possible I
guess but not sure how several cables, two routers and three modems, two
different brands, can all have the same issue.

Am I missing anything? Any other ideas? Thoughts?
