581874 2007-08-17 03:51:00 Hi, This post could be quite long as I have tried all kinds of things to no avail. Hopefully someone can help.

I have a max/128k broadband connection with Orcon. The connection is shared through a U.S. Robotics USR9108 router (both aspects of which I am very happy with).

There are two internet connections to the router. The first and main one is my PC which I built and connects to the router via ethernet through the PC's on board NIC on my Gigabyte 965P-DS3 mobo (Marvell Yukon 88E8056 PCI-E Gigabit Ethernet Controller). The second is a my wife's new laptop which is connected via wireless.

After setting up the wifes laptop I wanted to see the performance hit through using wireless. So I used the Consumer NZ speed test site to check out the speed (www.consumerspeedtest.org.nz). I had run this a few times on my PC and knew the speed I was getting on the PC was a transfer rate of 260.6 KB I was very surprised when I was getting a result which was almost double the speed I was getting on my PC (transfer rate of 434.2 KB/sec). I checked it on a number of other speed test sites and the same pattern happened on all of the sites.

Initally I thought it was the router's ethernet connection, so I pluged the laptop into the router directly via ethernet and re-ran the speed tests. The laptop was still amazingly fast - much faster than the PC. This narrowed it down to the PC and not the router. I then thought it must be the NIC on the mobo so I purchased a new gigabit NIC off pricespy and installed it. After installing the new NIC, the speed tests for the PC using the new NIC were exactly the same than the existing onboard one - still half the speed that the laptop wireless connection is getting.

I thought Windows might be stuffed up and corrupted some settings so I reloaded a 'clean' image of my system partition and tried again - nope still half speed. At my wits end, I ended up re-installing windows from scratch to see if my image was also corrupted - nope still half speed.

So this is where im at - a bit frustrated but none the wiser. Hopefully someone will have an idea of what could be the problem, if anyone wants any more details reply here and I will get you the details ASAP.

Thanks

What network speed are you running the network at? 100.0 Mbps?

If you go to Control Panel > Network Connections > click on your “local Area Connection” and you should get a box called “local area Connection status” & in this box it should say all about your network, e.g. network status, duration, & speed, let us know what speed it reads.

By the way what OS are you running Windows XP? Vista? 		stu161204 (123)
581876 2007-08-17 04:09:00 Thanks for the quick response stu161204.

Yes its a 100.0 Mbps full duplex connection, I did try playing with the speed and duplex settings, moving it away from auto-sensing and over to a forced 100.0 Mbps full duplex connection. Unfortunatly every setting I tried was the same slow speed.

As for the other question, Win XP Pro.

Cheers

581877 2007-08-17 05:36:00 Just a rouge thought:rolleyes: It may pay to call and check that they (Orcon) haven't throttled you back for some reason.

Sounds like its not the PC's.

581878 2007-08-17 05:43:00 Unfortunatly not. As I said in the origonal post if i connect the laptop to the router via ethernet or via wireless I straight away get double the speed. Im sure it must be the PC.

Just for confirmation though, I rang them and no my connection has not been throttled.

Thanks

Opps! sorry misread that part:(

Have you tried plugging the PC directly into the router like you did the Laptop 		wainuitech (129)
581880 2007-08-17 07:09:00 yep, thats how the PC its always connected, via ethernet directly to the router. I have tried all four ports on the router with both the laptop and the PC and every time the laptop is double the speed of the PC.

Cheers

TCP Optimizer, you may be pleasantly surprised [I was]

It will make a back-up of everything it does, so you can roll-back if you are worried. 		decibel (11645)
581882 2007-08-17 08:48:00 I used TCP optimiser and while the internet feels a touch more responsive, it still runs at half the speed of the laptop (wired or wireless) connection .

Even though it didnt fix the issues, thanks for the advice about TCP optimizer - it was worth a try .

581883 2007-08-17 09:04:00 Out of interest sake, what AV are you running on the PC compared to the Laptop .

The reason I ask is the Latest Norton 2007 Internet security has a lot of Anti - every thing, like fraud protection . If you do have INS 2007, that may be causing the problem ? 		wainuitech (129)
