Networks Very slow connection over ethernet - wireless is fine

In my house we use wireless (built into the laptop)
and homeplugs;

• router
• xbox 360 & bluray
• gaming pc

The wireless is running fantastic pulling in 9meg on ADSL speed tests and 1Mbit download rates.
I've never had any issues gaming on the 360 (with lag anyway )

However on the gaming PC (on board gigabit lan (Vista 64bit)) I'm getting under 2meg on ADSL speed test's and under 100Kbps download rates.




Seriously WTF
I've tried:

• driver updates (There are no vista 64bit drivers that I can find)
• disabling IPV6 (apparently that works)
• setting manual IP's
• connecting directly to the router (no home plug)
• other Ethernet connection (mobo has two ports)

HELP

 

Have you tried a different cat5 cable.

 

Crap, I knew I forgot something in the list, yes I've tried that.

 

Have you tried the laptop using the cable .

 

Right I've just tried the laptop on the cable (home plug & directly to the router, pretty much the same results)

But the wireless is far better for some reason, I thought wireless wasn't suppose to be this good lol.

 

I would check the routers settings, could be some thing needs changing worth a look.

 

What should I be looking at/for?

BTW


Heres a link to my results.

Also:

 

have you reset your tcp stack and all that jazz?

homeplugs aren't perfect by any means - could well be slower than wireless from what i've read. although directly into your router you should hit tops.

and like - proper drivers, so so likely that's the problem.

 

So when the laptop is direct to the router do you get the same results as the home plug.

 

Are you only worrying about Download Rates?

You wont be getting Lag at those speeds, so your 360 could be getting the same speeds.

 

If you mean the netsh int ip reset c:\resetlog.txt thing, it doesn't like that at all. worked this time, so yes I've done that, but no difference.

pretty much yeah.

Pretty much yeah, I can't understand why the connection is so slow, I noticed this when I was downloading a patch of a game.

 

If you log in to the router's control panel thing, is there a setting to do with half/full duplex and 10Mbit/100Mbit? If it's set to auto it may be defaulting to something slow, so force it to 100Mbit/full-duplex if you can.

Also, what type of cable are you using? Straight vs crossover may make a difference.

 

What model of homeplug are you using, and if you have it, when you fire up the homeplug utility what throughput does it say you're getting?

Have you enabled encryption?

Have you got the homeplugs directly into the wall, or on an extension lead?

Have you got any kind of "conditioner" attached to your ring main?

Is either homeplug near a source of em/microwave interference?

 

make sure homeplugs arent near electrical wires or anything with microwave interference, for those will cause interference. Also, check the routers settings..

 

This is probably irrelevant, but anyway ...

Microsoft have just today asked me to install an update to my ethernet as part of a Windows Update. When I installed it, I lost internet connectivity altogether: going back to the driver on my motherboard disk fixed it.

I'm also on Vista 64.

 

If HomePlug refers to powerline conversion (PLC)/ethernet over powerline there are several good reasons for the low performance.

First off, the technology is slow all by itself. Second, there can be a huge difference in throughput depending the make and model of the PLC hardware and products from different manufacturers definitely don't mix and match (although I don't consider you to mix and match). And last, depending where you live (e.g. flat or house) there might be more or less interference. Also, the electrical wiring of your home comes very much into play.

Generally speaking, PLC makes it easy to setup a home network, but it doesn't excel in the performance area.

 

Sounds like a router issue. What router do you have?

1. Try disabling QOS (in your router settings)

2. Try resetting it. First try soft reset and if that doesn't help try hard reset (aka reset to factory default settings)

3. You might try statically setting the speed on the NIC's properties (Computer Management > Device Manager > Network Adapters) to 100 mbps Full Duplex

 

I have 85mpbs homeplug and it works quite well for a home network and my ping is usually the same or less than my laptop on wireless.

Your mileage may vary of course, but I restate the questions I asked above, for you to work through and see if these identify any problems:

 

Keir said:

so that means the issue is not in the homeplug. I think the router is auto selecting 10mbps instead of 100mbps.

 

I've had a check and the router is set to 100mbps
Also downloaded and install the homeplug software from the solwse site (manufacture ) and it says it's working at 55mbps
