Download and run this WinSockFix. Reboot comp and post a new TCP Analyzer report:

http://www.softpedia.com/get/Tweak/Netw ... kFix.shtml

Where are you located and what speed did you pay your ISP to give you?

patrickwoo91 · Post by **patrickwoo91** » Tue Feb 20, 2007 4:46 am

thanks for uber fast reply.... i am just about to instal winsockfix...

I am located in australia with iinet adsl2+ (24000kilobits)

The speed ive seen on my line is 2.0MB for like 1 second and then slows down to 1.3MB which is the normal max i get for torrents.
My average typical speeds for torrents are around 1.1 MB though.

Also sorry for the trouble, recently i have been getting bad speeds on internet explorer? such as rapidshare (200-400KB/sec) and speedtest.net sydney server been geting high pings of 95ms where used to i got 15ms.(5000kb/sec) from used to of over 10000kb/sec

Troger can ytou help me fix this problem cause you helped me solve a different problem before.. thankyou in advance

The reason I said "That sounds good" is that your RWIN is unstuck and has reverted to default value of 65535. That is why your speed halved.

No. First use the custom setting I have given with TCP Optimizer.

Do speedtests at test server in Australia to check your speed

TTL should reduce. Why it has become 51 from 64 is that your signal to Speedguide took 13 hops. Each hop consumes one TTL value.

patrickwoo91 · Post by **patrickwoo91** » Tue Feb 20, 2007 5:16 am

yer speeds on sydney speedtest.net server are still the same...rapidshare files have increased by 100KB....
is that all you can do to max my internet connection=(???

thanks for your help btw! much appreciated

trogers · Post by **trogers** » Tue Feb 20, 2007 5:21 am

No, there are more things to check. Setting registry values is only the first step. Next you have to check for possible problem with signal quality.

Do a tracert to http://www.yahoo.com and post.

You are not using a router?

Tracert shows some busy traffic (hop 6) to the US.

Do some speedtests at this link using the Aussie test servers and post the results:

trogers · Post by **trogers** » Tue Feb 20, 2007 5:45 am

Your NetGear is not setup properly. If it is working as a router, the IP address in hop 1 will be 192.xxx.xxx.xxx and the 3 ping times <1ms. So it seems you may be connected through 2 modems.

Make sure your NetGear and modem are placed a few feet apart.

patrickwoo91 · Post by **patrickwoo91** » Tue Feb 20, 2007 5:52 am

OKIES ive moved them a few feet apart but what does that exactly do??

Take out the user manual of your NetGear and reinstall the setup. Make sure you choose PPPoE setting to suit your ISP.

Disable RIP (rest in peace?).

For open DNS I use this because I surf to the US often:

Do another tracert to see if your router appears in hop 1 and see what ping times in hop 2, your modem.

Do not choose bridge mode and turn off UPnP. Your router is still off.

If possible, click "WAN" and post the info of the WAN page.

In bridge mode, the router function is turned off. You should not run it in bridge mode.

To service other computers, make sure DHCP server function is turned on and the router will issue LAN IP address to your computers automatically.

If you need to do port forwarding, here is a website that guides you through the steps to set up static LAN IP addresses for each computer and how to port forward:
