So i have been using wireless for a while now but knew i could get better speeds with an ethernet cable so i decided to buy a 20m Cat6 cable. The problem is when i plug it in my internet speed drops to 0.3 mb/s so its unusable. Anyone heard of this before, thanks.

Disable your wireless first.
Plug the ethernet cable in.
Go to properties of "Local Area Connection".
Does it say you are connected at 10 Mbps, 100 Mbps or 1 Gbps?
What is the device you have plugged the cable into (e.g. your ADSL router)?
Do you have another machine (e.g. laptop) to test the cable?

ADSL is a type of internet connection common on phone lines.
Does the second computer give you a different result with the same cable?

cat6 cable is compatible with most/if not all cat5e hardware, or should be.

Is your router a modem router and was it sent to you from your isp?

Reason i ask is i lanned at a friends place once and we connected his gigabit modem router with long cat5e cable to the living room. The switch was only 5e but the internet was fudged. We tested the cable and switch and they were fine.

We bought cat6 switch and cat6 cables to go with the computers and we were happy.

His isp given cat6 router did not like the cat5e cable or switch. Might have been switch actually but anywho, my point is we experienced bit of fussiness here.

Could be the router not agreeing with the cable. Or one of the cable ends is not making contact or wired properly.

If you can try another cable, youd have been given a shorter cable with the router? If it is a modem router that is, they'd usually package one along with and if the modem is an old one, the cable would be cat5e.

You might try updating your lan drivers.
Since it sounds like you've been using wireless for a while.

I finished trying it on the other computer and it seemed to work fine. Normal speeds.

following up on davcon's reply, since it appears to be working on the other computer, is you go to your motherboard manufactures website and download and install/update lan driver.

also was your computer prebuilt or did you build it? prebuilt would think lan software would be installed, but if you built it and never got around to installing lan drivers would make more sense.
