New PCI-E Wireless Adapter Only Connects to Old Router

[Moroco Branting]

Problem Background:

I have been having trouble with a brand new ASUS PCE-N15 PCI-E wireless adapter. Upon installation of its drivers and utilities, I discovered that if it did discover my home network (transmitted from my default CenturyLink ActionTec modem with wireless), it would either not connect, or connect and claim that there was no internet available. All other wireless devices in the house could connect fine, however. I also tried reinstalling in different locations and with different settings (using Windows 7's wireless functions instead of the ASUS utility) and nothing worked in trying to get the card to connect to my network using the modem. I finally had to break out my family's old Netgear router and set up a new connection point, which the card connects to flawlessly but with extremely limited bandwidth (1/3 of what connecting to the modem directly provides). Upon searching the internet for the manual (not included with adapter), I found that the manual was useless in answering my issue.

Question:

Is there a work around to get this adapter to connect to my modem? Having the router set up is a bear because of space and power constraints, as well as the bandwidth limitation. I have tried downloading newer drivers from ASUS, but they were just the files with no instructions on where to put them. Should I just send the wireless adapter back to ASUS and buy a higher quality one?

System Specs:

AMD FX-6200 processor
Gigabyte 970A-D3P motherboard
HIS IceQ Radeon 7870 graphics card
ASUS PCE-N15 wirless adapter

Notes:
>I have had this issue with two other PCI-E wireless cards, which I had to return.
>The card is physically misshapen from the factory. When in place, the back bracket does not touch the case, and is 1-2mm off everywhere after trying to adjust.

Do you have WiFi set up on the router so only certain devices can connect maybe?

For the driver updates, if they are just the driver files, you can manually point Windows to that location when you update the drivers. Just right-click on it in Device Manager, select update driver and manually browse to where those files are located.
