Wireless PCI adapter works terribly on one computer, well on others

Hi, I have a ENLWI-G2 802.11g Wireless PCI adapter, chipset: RTL8185.

Router: Belkin Wireless G Router- 2.4Ghz 802.11g

I first used it on a system with Ubuntu 10.04 64bit  and windows xp 32bit.  It was very slow on the Linux partition, which i guessed was the drivers but I failed to get them working in NDISWrapper.  The xp partition was fine for a while until it also started to bog down.  It is very slow and very unreliable.  I then had a clean install of WIndows 7 64 bit, which I use now, and it continued to be very slow and unreliable.  

There is a good floor between me and the router, but when I installed the adapter in the old computer downstairs and put the router @ same distance and same obstacles, it preformed as it was expected to.

I could use some help because I really don't have a clue to the problem.

First update to the latest firmware on your router and update to the latest drivers on your adapter to see if that resolves the issue.

Thanks, but all seems well, what's next =P.

My configuration is kind of weird: splitter for tv ->cable modem ->Ethernet modem w/ 2 phone jacks ->wireless router.  I recently got a new modem, after the problem started (I had an old one before), and *Fixed* I can't seem to configure it by typing the ip address in the browser address bar.*Fixed*

Thanks again, I hope this problem can be solved so I can start using my new computer build properly.

Most routers don't like settings being changed by wireless, use a wired connection. Also reset the box and try again. It's also a common problem with wireless performance under Linux using ndiswrapper to be weaker than windows. You might want to search around the power-saving features and see if there is a "Transmit Power" settings to adjust.

Could not see any Transmit power setting.  I have taken the card out of the computer in case it damages my other components due to stress.  Other wireless laptops work fine in my household's wireless connection.

I am using a wired connection to tweak my settings and I have reseted and power booted my cable modem, switch, and router multiple times.

I really would like to solve this problem, but is it really just a bad pci adapter and I should get a different one, it is actually recently bought.

It would not be the first time I've had to buy another network adapter. I checked the one you had and the reviews from people are not that good.
