Packet Loss
zilspeed - 30/1/08 at 09:34 PM

Need help with the above.
For about 5 days now, my internet connection has been rubbish. BT Internet say, there'sa nothing wrong, but my experience from this end says different.

Can any networking savvy types have a look at these numbers and tell me anything constructive ?

Thanks for any help that anyone can provide.

I'm experiencing similar difficulties but am on Orange LIvebox broadband

I cant access www.josbrownlie.co.uk from my home machine but can from work or mobile so will be very interested to see what the suggestiuons are to get you back up and running

RichardK - 30/1/08 at 09:52 PM

Have a try of some of these tools if you haven't already LINKY

You may be dropping fragmented packets due to an incorrect mtu window, the tweak test will show you this anyway and point you to an application called Dr Tcp if you are.

Cheers

Rich

I had similar problems. My ISP told me to enter thier DNS servers in the Network Connections Internet Protocol properties. See attachment. Find out your ISP's and try the same....worked for me.

I had a few problems with my Orange internet connect the back end of last week. It turned out to be a problem with their DNS servers, and I switched from using their ones, to the ones provided by OpenDNS.com

NO problems since then.

Looking at it I would say MTU as well. Seems things go wrong after its left your control, suggesting your ouput is wrong. What spped adsl do you have, or have you been "sold". Are you with BT? If not could be a bad case of LLU, which is what Tiscali are currently ballsing up to cut costs.

This site may help with MTU issues : Link

If you suspect its a DNS problem, Keep one of your ISP's DNS entries, and use some others.

I use ones from BTInternet, then BTNet. Always seems to work for me.

BT DNS servers were a tad unreliable when I used them to the extend I always had a Pipex dns server in my TCP/IP settings.

However lost packets point to either an MTU setting problem (MTU is set too high) or line quality/card at exchange problem.

MTU problems used to be very common in the early days of broadband -- loads of utilities out on the internet for setting it for best connection speed.

Thank God! For a minute there, I thought you'd had a terrible accident.

BT MTU setting tool

Click on the link below and choose 'save the file to disk' when prompted by your browser.

http://www.zensupport.co.uk/KBResources/Downloads/MTU/NetworkOptimiser.zip

Once downloaded, unzip the file and run the program. Click Next and then read the user agreement. If you agree with this click I Agree.

You will now see a list of network devices. If you use a router then alter the Local Area Connection, otherwise modify your modem. To do this click Edit. You should see your current MTU and then a box which allows you to alter this value. Change to one of the values specified above. Click OK and then Next.

Once you have changed your MTU value you will need to restart your computer. Perform the speed test again and see if the change has improved your connection performance. If it hasn't, then try the other values. To reset your computer to it's normal default, change the value to
