[Bug 663395] [NEW] Abnormally slow network connections

[Carroarmato0]

Public bug reported:

In Ubuntu 10.10 with the latest updates, I noticed that initializing
network connections takes ages to establish.

Symptoms are:  Firefox and Google Chrome seem to take a long time to
resolve the url.   Pinging hosts also takes it's time.

Not only on the wireless network, but also on the ethernet connection.

I tested to make sure it's not hardware related by connecting from
different places, trying to connect from other computers, and booting up
Windows on my same laptop to make sure it's not hardware or ISP related.

I also performed DNS lookups by running  nslookup and try to resolve the
same different websites I've tried to reach through the browsers and
ping, and DNS resolution happens instantly.

All my tests have led me to suspect the latest kernel version.

Note that once the connection is established, traffic flows at normal
expected speed, untill another connection has to be started, then the
waiting game repeats itself.
