Wireless not getting picked up on one computer in the house

[haser1234]

So I recently purchased a new PC from PC specialists. It arrived a few days ago and I'm having some trouble connecting it to our internet. Chipset drivers installed, wireless card drivers (Marvel Yukon 88E8056 PCI Gigabit Ethernet controller) installed, etc. Not left anything out in terms of drivers and firmware. So here's the problem, this computer barely even connects to the internet, sometimes one bar of signal, sometimes just nothing whereas my laptop (in the same room) that uses an Intel(R) WiFi Link 5100 AGN has full bars. Originally, I thought it to be the routers problem (it was nearly 8 years old) so we changed the router, we now have a Linksys E2000 wireless N router. I also thought it could be the wireless card, so I switched the PCI slots it was in which made no difference, and also purchased a usb network adapter to try that out, which also didn't work. I also tried fiddling with the security settings on the router, switching from wep - wpa and to no security at all and none of this helped. I'm stumped, and would really appreciate some help. Thanks in advance

Positioning the wireless router

From Microsoft help:

Put your wireless router somewhere where it will receive the strongest signal with the least amount of interference. For the best results, follow these tips:

*

Position your wireless router in a central location. Place the router as close to the center of your home as possible to increase the strength of the wireless signal throughout your home.
*

Position the wireless router off of the floor and away from walls and metal objects, such as metal file cabinets. The fewer physical obstructions between your computer and the router's signal, the more likely that you'll be using the router's full signal strength.
*

Reduce interference. 802.11g networking equipment uses a 2.4 gigahertz (GHz) radio frequency. This is the same frequency as most microwaves and many cordless phones. If you turn on the microwave or get a call on a cordless phone, your wireless signal might be temporarily interrupted. You can avoid most of these issues by using a cordless phone with a higher frequency, such as 5.8 GHz.

let me take a guess and say that ur OS on the new pc is win 7 and the old pc is xp
if thats so then u need to contact Microsoft for help cuz win 7 is having alot of trouble with wireless networking in most cases to be sure just try to check ur wireless connection on safe mode with networking and it will work like a charm if it doesnt work then it win 7 is innocent and try the tips above.
