Virgin broadband packet loss- HELP!!!

[joey122mac]

For months I have been fighting with Virgin trying ti get to the bottom of why when I connect to work I keep on getting packet drops

Recently even BBC news wecasts have been slow

I have a 2MB broadband connection and am the only user of the line.

I do not know what to do - Any ideas?

Does this mean much ?

Is this good / bad?

Your
upstream transmit power level
downstream snr
downstream recieve power level
readings might prove to be more useful in trying to diagnose problems with your connection that the data you have posted.

When looking for a bottleneck a tracert is more to the point that a ping.

Thanks - Thats great - How do I get that iformation?

Heres traceroute:

$ traceroute www.google.com
traceroute: Warning: www.google.com has multiple addresses; using 64.233.183.99
traceroute to www.l.google.com (64.233.183.99), 64 hops max, 40 byte packets

Look at how many packets were lost in the ping -f - Is this not a problem?

That would depend on your modem type. But mostly its 192.168.100.1
If you are asked for a user name & password its root for both.

You may want to try removing your router whilst testing.
