Hmm. I find it very odd that you get slow speeds in standalone mode as well. Can you run the command "top" (q to exit) and see if anything is putting a big load on ClearOS? Also what is the output of "hdparm -tT /dev/sda" (change sda to whatever your hard disk is and it could be hdX and not sdX).

If the switch is the issue then download speeds into ClearOS should not be affected. Can you do a wget on a file on the internet to check the download speed into ClearOS when ClearOS is in gateway mode? Also, what is the output of:

ifconfig | grep eth -A 1

cat /etc/clearos/network.conf

cat /etc/resolv-peerdns

Hi Nick,

Internet speeds were still slow after the update and in standalone mode.

I then went ahead and changed everything back to the way it was.

D-Link as bridged modem which goes into nic one on ClearOS as PPPOE and the other nic as LAN with DHCP enabled. The ClearOS LAN is connected to a Gigabit switch which then has other devices connected to it as well. As soon as I changed to this setup, the connections dropped once again. Do you think the switch could be the issue?

I don't know what's happening.

I am really liking my ClearOS box and would be very disappointed if I have to stop using it.

Thanks for your help.

That is up to you. You say you saw reduced speeds when it was in standalone mode before. Do you still see them? If not, try changing over to gateway. If you don't change it to gateway you'll never know.

Hi Nick,

I have just updated the driver as per your instruction.

Should I change the modem back to bridge mode and configure the ClearOS to be in Gateway mode again to test it all or can I leave things the way they are now?

Thanks for your help.

The 82574L has issues with the stock driver. Please can you install the latest kmod one:

yum --enablerepo=clearos-dev install kmod-e1000e

You may need to reboot afterwards.

Hi Nick,

Thanks for your reply. Sorry for the delay in mine.

Here's the output as per your request.

I changed my network setup as follows.

My D-Link modem (IP 10.1.1.254) is no longer in bridge mode, but is connected to TPG (ISP) directly. It also has DHCP enabled (range 10.1.1.25-10.1.1.35).

The Ethernet cable from the D-Link goes into a Gigabit switch.

That switch then has other Ethernet cables connected to other devices, one to a WAP (10.1.1.253), one to my laptop and one to the ClearOS box, which I have changed to a Standalone-No Firewall mode. The Intel NIC is configured as a LAN interface (10.1.1.3) and I have not configured the other NIC at all. I have disabled DHCP on the ClearOS box. As far as I know, this makes it a simple file server.

However, I have noticed that even though the ClearOS box is no longer in Gateway mode, when it is powered on and connected to the network, my Internet speed drops drastically. If I switch it off, everything is OK.

My suspicion is that I have screwed something up on my ClearOS box OR plugging everything into the switch isn't the smartest idea (as I said, I am weak when it comes to networking).

I would appreciate it if yourself or anyone else can help.

Thanks again!
Sri
