DSL Connection random drop

Zorin 6 x 64.

I use two connection methods. My main is cable DSL and also a mobile broadband. The USB dongle is fine but I'm experiencing random drops with the cable. When I first configured this connection a pop-up window appeared with the username/password details I had entered and clicking OK connected it. Thereafter whenever I boot it mostly connects automatically although on some occasions this window appears again and I have to accept it up to three times before it connects. However, in use at random intervals I suddenly lose speed although the connection is still live. It can take 5 minutes for a web page to open, but this proves that "a connection" is still there. Re-booting usually solves the issue. The only non-standard configuration I made was to change my ISP's DNS servers to those from Norton. This machine is dual booted with Windows 7 and I do not have this problem when using Windows so it can't be a card or cable error. Any ideas? Can I bypass the network manager by configuring this using pppoe conf?

Hi,

open your network connections editor (click on network icon > edit connections > wired connection > edit) and make sure that your IPV4 method settings are set to "Automatic DHCP". Also make sure that it is checked for all users and connect automatically.

Also, have you fully updated your system:

Let us know if this helps.

Thank you for responding. There is nothing listed under wired connection, (it is blank) only the DSL details which I entered myself.
The system is fully updated.

Please post the results of

Code:

lspci -nn
sudo lshw -c network

When you experience loss of internet speed, also post the result of

Code:

dmesg | grep -e eth -e 8139

Thanks. It happened again soon after I booted this morning but unfortunately I hadn't got to this post by then and rebooted which fixed it. I've copied the code now though and will run the query next time it happens.

I was wondering if maybe this is something to do with my ISP who is highly unreliable but the other choices for cable where I live are even worse. I've also tried to spend a fair amount of time connected with Windows and have not had the same issue, although this could just be coincidence.

I forgot to mention too that after installing I replaced UFW with Firestarter and enabled ICMP filtering to achieve stealth. Not sure if there are any implications here?

Well it happened again although this may or may not be related. Usually there is no indication from the network icon or anywhere else that anything has changed other than web pages stop loading. This time however the network icon appeared with a red cross suggesting that the connection was unavailable. I also rebooted immediately into Windows and got a WAN miniport error 651 which suggests my ISP is in fact down. Here is the code though just in case something is relevant.

The system is fully updated.

Hi,

in your image, where it says "Method", have you tried switching it to "Auto DHCP" ?.

Regards Wolfman

There is no option for DHCP. The only two other options are Automatic (PPPoE) or Manual in relation to DNS. I need to use the one shown because I have to use Norton DNS for my work which are the server addresses shown in the bottom of the window.

Hi,

this might help you:

Regards Wolfman

Thank you for the information link.

There is one other thing I have since noticed that may or may not be relevant. With other distros, I always check to make sure my DNS changes have been configured correctly or not overwritten on reboot using the command. $ cat /etc/resolv.conf which should return my Norton server details. In this case though the nameserver returned is 127.0.0.1. When I check using the Norton DNS online page though, it says I am using their servers as configured?

Hi,

sorry but I cannot be of more help, I have never set up network servers etc and can only refer you to the Ubuntu how-to's as I find them.

Is this of any help:
