Speed Test PC Issues

Hi All,

Hope you can help! I have just had Fibre installed through TalkTalk. I have two PC's plugged into the Router. One PC is showing a speed of 38Mbps but the other is showing only 1.5Mbps. I'm guessing there is probably a simple explanation for this, and I'm missing it...

Any help would be greatly appreciated.

If the slow PC is an XP machine, then the RWIN may need tweaking

http://www.dslreports.com/tweaks has a test that can check this and the DrTCP tool to correct it.

Also worth checking the Ethernet cable is connecting at 1000 or 100 Meg and not 10 Meg.

Thanks Mr Saffron

I will try out the tcp tweek. As long as its relatively straight forward that is!

Will let you know.

Cheers

Sorry

Just remembered that it is Windows Vista....

How do I check the cable connection speed?

Should be part of the properties for the network card in the Network and Sharing centre

Hi Mr Saffron

It would seem to be running at 100Mbps

I checked in Network and Sharing Center and clicked on View Status under the Network Connection it shows a speed of 100Mbps, so I guess this is OK ?

I have just read that Vista has an Auto Tuning TCP which can be disabled. Is this a good idea?

Hi

Thought this might also help, I have disabled the TCP Auto Tuning and run a dsl report details of which are here

Hope this helps

I would turn the auto tuning back on.

The RWIN in that report looks too small to me, but auto tuning should scale within a second usually. So run again with scaling on.

Hi Mr Saffron,

I have turned the Auto Tuning back on as requested and have run the report again.

Let me know what you think !

This may help, but I have found that the 'auto-negotiate' speed setting in Network properties reaults in a higher default speed than expressly setting it.
