Hi guys.

I'm pretty new with LInux so bare with me. But recently I've just switched my Internet to ADSL2 and I get terrible speed at connection (or maybe lookup).

Before this ADSL2, I've been using Wireless Internet Connection, using something like UnWired here in Australia. It's also using a modem connecting to Ethernet port, but PPPoE connection is made by connecting manually in the system-config-network.

I am currently using Fedora Core 6. The ADSL modem is NetComm NB5. My internet provider is ExeTel (which is the same provider as the wireless internet beforehand, just different service). I am using the latest Firefox release for the web browser.

With this new ADSL2 connection, I assume to use the same utility "system-config-network" and activate the first ethernet drive using DHCP. Everything seems to work well because I can actually open pages and connect to the Internet.

However, there's a very noticable waiting period for looking up or connecting to every website. For instance, when I type in "http://www.google.com" in the address bar and press enter to activate, the Firefox status bar shows "looking up http://www.google.com" for a long period of time before actually opening up the website.

There is no issue in the speed of the transfer speed itself, since once it opens, it actually downloads very fast. Browsing between pages on the website (once connected) is also very quick as expected of an ADSL2 service. However, once it needs to download certain features such as scripts or picture from other websites, they take a long time once again - which is also expected by observing the first problem mentioned above.

The funny thing is this same problem does not exist in Windows. In Windows (same modem settings, untouched), every website works as they should be, fast and no long "looking up" period.

I like using Fedora Core Linux a lot better now, so please tell me if you know a way to fix this problem. Thanks a lot in advance, guys!

Cheers,
Henry

Hi henry_shadowjet,

Are you using the same DNS servers across both OS's? All the problem seems to be is that the DNS server is taking a while to process the request.

cat /etc/resolv.conf and verify that the IP addresses are the same as the ones configured on your Windows box. As well as that, ping both of them, and make sure you get a response from both, and that the ping times aren't overly huge.

Looking at the Exetel site, your /etc/resolv.conf should look something like this:

As for the Firefox browser, make sure you don't have any proxy settings configured. Tools > Options > Advanced (Tab) > Networks (Tab) then click on Settings. Select "Direct connection to the Internet".

Let me know how you go.

Hi Kristijan,

Thanks for your help.

Not that I disagree with your solution, but DNS configurations are configured on the Netcomm NB5 modem-router, not the PC.

But I will try and go ahead with that suggestion after I reboot to Fredora once again from this stupid Windows.

Thanks again.

Kristijan,

That sure solved the problem! Thanks a lot! Editing /etc/resolve.conf sure does the trick!

But I'm wondering though, because resolve.conf is generated by system-config-network from DHCP, I'm trying to figure out a way where I can make my modem router (Netcomm NB5) to broadcast these DNS when assigning IPs through DHCP, unfortunately the DNS ranges broadcasted must be in the network range (192.168.0.x).

I'm trying fo figure out if there's a better way to do this rather than manually editing /etc/resolv.conf everytime.

But thanks a lot for your help! Appreciate it!

Regards,
Henry
