trying to figure resolve slow ADSL access

[SilverNodashi]

Hi all,

I hope someone can help me with this one.

A client of ours have a 4MB ADSL line, as per the Netgear DG824GT router:
DownStream Connection Speed 4096 kbps
UpStream Connection Speed 512 kbps

The router is setup in bridged mode, which is then connected to an OpenSuse 10.2 Linux router which initiates the ADSL connection. From there it shares the connection with 3 other PC's. Internet browsing, etc, VPN, etc is all very slow, as can be seen here: http://www.speedtest.net/result/900202789.png

The line used to be a 384, with horrendous slow speeds and we then got telkom to upgrade the line. They also reset the ports, but it's still very slow. Much slower than my 512K at home.

Does anyone know what I can do to improve the speed?
How, if at all, do I set the MTU on a Linux box which establishes a PPPoE connection?

You first need to Elimite the ADSL line, ISP and router before you can ask any Linux related questions I think...

Looks about right for IS

Do a traceroute to some local and international servers.

+1 This problem is probably not even linux related.

Probably not, but the closest thing i've had to this was my default gateway not being set up correctly, which caused looooong "resolvings" and lots of drops... which then seemed like a slow connection speed if you weren't looking closely. So if it is Linux related, i would start looking there.

Try disabling IPV6 in the distro and in firefox (if that is what you are using).
In the distro, goto yast, network devices, network settings and then global options. Untick IPV6 - it will need a reboot.
In firefox, type about:config in the address window, and then in the filter window type IPv6 this will bring up "network.dns.disableIPv6; true" If it is true, IPv6 is diabled. If it is set to false, right click and toggle it to true. You will have to restart firefox for it to take effect.
or you could use another browser like seamonkey, which is very fast.

how about setting up a connection on the router (ie set it to PPPoE mode) and test if the line works fine then?

What are you doing posting in a thread from 2010?

And why are you posting windows command output in the Linux section?
