I see you haven't gotten a response to this. So, I'm going to have a
crack at it.

That's good enough, as long as you either ran
sysctl -p /etc/sysctl.d/disableipv6.conf
afterwords, or simply rebooted. The rest I consider to be
overkill. You still haven't explained why you're disabling ipv6 in the
first place. Do you have ipv6 connectivity which you suspect to be
buggy? If you only have ipv4 connectivity then an enabled ipv6 stack
is likely not the cause for your slow internet.

Like I said above, overkill.

That's not at all bad! It's better then what I get on a nearly 3 meg
down adsl connection from the gateway connected directly by wire to
the modem.

That's worse, but it's still better than what I get when pinging
that.

You have 23 RX packets. That's probably nothing to worry about, unless
it keeps going up as you use your internet connection between
reboots. I don't see your nameservers and routing as being a problem either.

I tried that too exactly as Scot posted it, but am told the -w flag
isn't recognized. This is on a wheezy system. I prefer wget myself, so
I suggest you try that instead
apt-get install wget (you should already have it installed anyway)
