Internet speed fractured in Vista!

[djmorgan]

Right now I have XP Pro SP3 on 1 laptop and Vista Ultimate on another I have an ADSL 2+ Internet connection

With the XP machine I get 28000+kbs down and 750+ up, using the same connection just swapping the net cable Vista does 9000+ down and 750+ up.

I have tried every "Netsh" combo detailed here and elsewhere with nil result what can be wrong with Vista?

Get a newer NIC driver. Disable IPv6 in the NIC settings.

I have the latest Realtek RTL8168B/8111B Family PCI-E Gigabit Ethernet NIC (NDIS 6.0) driver and stopped IPv6 in favour of IPv4 no change!

Try setting the speed to 100 Mbps / full duplex instead of auto. Try disabling your firewall and anti-virus and see if they are causing problems with downloading.

 

[djmorgan]

Thanks for your assistance tried both your suggestions, I run Eset Security so turned it off, if anything changing the speed seemed marginally slower.

 

[sidney1st]

In Power Options, do you run High performance option?
I run Eset too, did you disable both Windows firewall and Defender?

 

[djmorgan]

Yes full power option, ESS disables native firewall as for defender it's not the easiest to turn off! I've removed it from the registry run, it does not appear in msconfig and or any running services or processes so I think I nailed that sucker too!

MY XP system is nearly the same as the Vista system in terms of AV and firewall, I can rule out the modem as I only swapped the net cable from one to the other.

Google produces a lot of complaints about internet speed with Vista, now I have to say that my system with the internet does not seem slow! but this could be due to the processor power

Do you have a non-Vista computer to test the internet speed with?

My Vista x64 Ultimate network performance is the same as XP x64.

Cabling
NIC drivers
NIC settings
router problems
Firewire and anti-virus interference

Your CPU is GHz and your network is Mhz. I doubt the CPU performance is the problem unless your CPU is running at 100%. Turn on the gadget with CPU/RAM usage.

Are you using a CAT 5, 5e or 6 cable. I use on CAT 6 for 1 Gbps. The backbone from second floor to basement is CAT 6 plenum grade solid core shielded. 5e is minimum for 1 Gbps.

Firewall and anti-virus can cause issues. Make sure they are disabled.

Did you try directly to the modem? Bypass your router. Maybe the router has issues.

 

[djmorgan]

Yes! my XP machine conected to the same cat cable and same route does over 28000+ kbs down and 700+ up.

This is why I know it must be a bottle neck in Vista

I'll check the other items you mention

 

[SCSIraidGURU]

XP on same computer rules out cabling and router issues. I would check speed, duplexing, and drivers.

Hey DJMorgan,

Try out this tutorial, It should help you increase the network speed.

Just for fun I tried the tutorial. It crippled me. I was not broke so I didn't need it I guess. It took my Gigabit Ethernet connection down to 100. Reversed and all is well.

My details:
No TCP tweaking, bone stock.
Screaming comcast here on an Arris cable modem.
Vista 32 and 64 bit machines.
Trendnet's latest Draft-N router.

Try swapping the cables ans see if the speeds change....

Well your right about that one

 

[djmorgan]

I really appreciate all your help and thoughts on this matter.

I have tried every Netsh comand known to man and then some! first placed i looked was the tweak tutorial.

I have swapped out every cable even though XP worked great using them.
I have the latest nic drivers, they are actually the only drivers available so I can't roll back

But keep the thoughts and suggestions coming please

The latest driver for this NIC can be found at one of the links below, Give one of them a try and let us know if there is any improvement.

Thanks mate, that is the version I had but I ran it again anyway and did a repair, sadly no improvement

Could you take a screenshot of the Ethernet NIC properties - Advanced tab for me?

What is your speed and duplex set to? Try 100 Mbps /full duplex. See if that helps.
