Packet loss with Ubuntu 11.10

rated 0 times [ 2] [ 0] / answers: 1 / hits: 3828 / 2 Years ago, mon, may 16, 2022, 5:27:01

I have a machine with Windows 7 and Ubuntu 11.10

In Ubuntu I have about 30% packet loss when I make pings either to my router gateway or to an external site such as google.com, so my internet connection goes very slow.

Since the network works perfectly fine in Windows 7 (without any packet loss), I assume it's not a problem of the line.

Is there anything I could change in network settings or something similar in order to make this work correctly in Ubuntu?

I edit to say that I found my solution here (the problem was defective realtek drivers):

How do I stop my ethernet network connection from dropping?

I have experienced Packet Loss in Ubuntu, too under two circumstances:

Routing Issues when having multiple Interfaces in the same Network
I had two LAN Ports in the same network and the I suppose the routing of both interfaces overlapped and they took turns in sending/receiving from and to the network. The problem stopped as soon as i disabled one interface
```
$ sudo ifconfig eth1 down
```

Connections are timing out because they tried to use IPv6 at times
Especially when doing DNS Requests while apt-get updating some repositories, even official ubuntu ones, cannot be resolved to an ip.

See https://help.ubuntu.com/community/WebBrowsingSlowIPv6IPv4 in this case.

Also you should give more information, like complete output of both

$ ifconfig

and

$ route

Under no circumstances should you need to remove network-manager or any other preinstalled network management software. They work just fine, when configured correctly.

I'm sorry that both points are rather blurry, but I guarantee, that both happened as I told them.
