In your first paragraph, you mentioned having bandwidth issues, but
what you're complaining about here is latency.  There's a big
difference.  Once you start a download, are you still getting decent
download speeds?

As for pinging their DNS servers, trying pinging something else instead.
RR's DNS servers suck (as others have mentioned in this thread).  If you
can ping elsewhere just fine, stop using their DNS servers.

I've said it before and I'll say it again DON'T USE RR's DNS SERVERS!
They suck, they go up and down like yo-yos.  Actually, they go up and
down like they're running Windows. ;)  Set up your own caching DNS
server.

Try to reach other sites by IP.  If you need them, here's a few:
www.yahoo.akadns.net. has address 64.58.76.179
www.yahoo.akadns.net. has address 64.58.76.222
www.yahoo.akadns.net. has address 64.58.76.223
www.yahoo.akadns.net. has address 64.58.76.224
cnn.com. has address 207.25.71.29
cnn.com. has address 64.236.16.20
cnn.com. has address 64.236.16.52
cnn.com. has address 64.236.16.84
www.google.com. has address 216.239.33.101
trilug.org. has address 64.244.27.132

A.GTLD-SERVERS.NET. has address 192.5.6.30
B.GTLD-SERVERS.NET. has address 192.33.14.30
C.GTLD-SERVERS.NET. has address 192.26.92.30
D.GTLD-SERVERS.NET. has address 192.31.80.30
E.GTLD-SERVERS.NET. has address 192.12.94.30
F.GTLD-SERVERS.NET. has address 192.35.51.30
G.GTLD-SERVERS.NET. has address 192.42.93.30
H.GTLD-SERVERS.NET. has address 192.54.112.30

Simply not getting good ping response times from their DNS servers
isn't a sign of your cable modem having issues.
