Slow NBN on Windows 7 but not on OS X

Answered

Our Telstra NBN service is connected through a Telstra Technicolor TG797n v3 Gateway with firmware 10.3.V.9, software variant BN. The connection to the computer is through an ethernet connection direct to the Gateway, and the ethernet cable has been tested OK.

 

On a Macbook Pro with OSX 10.10.3 a check at speedof.me consistently shows 25Mbps.

 

On an Asus Win7 64 bit Home Premium speedof.me reports less than 5 Mbps. Websites are also very very slow to connect (sometimes in the order of minutes). The Win7 computer was tested at a location with ADSL2, consistently reporting 7Mbps, the same as the MBP. The computer has also been scanned for malware and failing HDD with nothing found.

 

One difference between the two locations is that the ADSL2 does not have IPv6 configured, whereas the NBN location shows IPv6 to be configured. Does Telstra NBN now use IPv6? Could this be the problem? I was trying to test this theory by disabling IPv6 in the Technicolor but I could not see how to do it.

 

Any ideas?

Re: Slow NBN on Windows 7 but not on OS X

Hey @chuck_2330,

 

It won't be IPv6.

 

Not sure what the heck would be going on there, I use Windows 7 64 bit, and OS/X on a Mac mini, and have the same as you, but 100MB NBN

 

I don't get those results on NBN.

 

That's pretty wierd behaviour.

 

I guess if you tried swapping the ports around on the Gateway?  I wonder if it's a port issue on the Gateway?

 

Another thing to try might be to check the DNS entries on the Windows machine if you have them configured, just in case.

 

If you have eliminated malware, about the only suggestion I have other than that is some sort of connection watcher to see what your Windows 7 PC is doing.

Hope this helps.

Good idea. Thanks for the link. I'll do some more testing, perhaps using Google's public DNS 8.8.8.8 & 8.8.4.4
