Okay, then something is going on with your Wireless Adapter... You could try uninstalling the adapter from Device Manager, and then reinstalling the driver from scratch....
Hmm... I doubt there is a problem with your wireless adapter then, something else is going on. How about running a speed test on http://speedtest.net and see what it sees the speed is. Run it on another of your computers and compare them. Post the results here.
Edited the above post. Yes I have done a speedtest on this laptop and another one, I can't post results as it was done earlier on today but I can tell you that my laptop gets between 0.50-0.75mbps download while the others get the full 8mbps download.
One final thing you can try is to create an Ad-Hoc network. Essentially, these networks are hosted by a computer with a Wi-Fi adapter, so you can setup a laptop as a Wireless router if you don't have one (or a second one in this case). The instructions to create one depends on the OS, but for Windows 7 and Vista, go into Network and Sharing Center, then click on "Set-up a new connection or network." Perform this on a DIFFERENT laptop than the one that is having the problem. Then choose an Ad-Hoc network at the bottom of the list. Also, the laptop you choose to host the network must have an ethernet connection to the router itself. After you create this network, on the computer with the problem, login to the Ad-Hoc network you created. Next, go into Network and Sharing Center on the second laptop without the problem, click on "Change Adapter Settings", and then right-click on the wireless adapter, and choose properties. Then click on the sharing tab. Check the box that says "Allow network uses to connect through..." and choose the ethernet connection from the drop-down list nelow. Apply the settings and close the dialog boxes. Hopefully, if all this worked right, the laptop that has the problem should be able to get the full speed because it is connecting to the internet through another computer.
I realize the above is a lot of steps to do, but I can't think of anything else to attempt. If you don't want to try the above, you will need a new Wi-Fi card is my best guess. If the above does work, then something is wrong with your Wireless router... After testing this, reverse the steps for sharing the connection, and to shut down the Ad-Hoc network, simply disconnect the 2 computers from the Ad-Hoc Wi-Fi network.
That does help, something else is going on (again). That leads me to believe that there is some kind of incompatibility between that model of laptop and your wireless router (a software or hardware incompatibility), else all of the computers would have the same problem... You could try creating a standard account on your laptop and see what the speeds look like on that account.
It seems hard to believe that a brand new laptop has a Wi-Fi problem. Would it be a help to you that my sister has the same model of laptop, and a month or so ago I was using the guest account on her laptop and it had the same problem? I'm not sure about the administrator account on that laptop however.
Do you have any idea what the incompatibility could be? I tried changing the wireless channels on my router and that didn't help. I will try creating a normal account, too.
That seems like a long test to see if the problem lies with the laptop or the router, which is pointless because I already know it's definitely a laptop problem as the other laptops are fine.
Alright then, I'd say the problem lies in the Wi-Fi card. You can get new Wi-Fi cards for relatively cheap. If you don't want to open up the laptop to switch the card, you can also just buy an USB Wi-Fi adapter.
Well, it shouldn't be the wireless radio (802.11G, 802.11N, etc.), that wouldn't hinder the speed, even if it was 802.11G. The only other thing I could think of would be maybe the frequency at which the signal is being broadcasted. You said you changed the channel, but maybe by changing the frequency you can fix it.

Edit: After a few minutes of it being wired it started to get back to normal speed. Laptop is getting full speed while wired.

Have you tried directly connecting your laptop to the modem/router with an ethernet cable to check if the same thing happens there?

:(. Do you have another router you can connect to? If not, do you have another laptop with a Wi-Fi adapter in it?
