I bought a tp link 450 Mbps wireless N Dual band pci express adapter for my computer.
Here is a link to the one I have: TL-WDN4800 - Welcome to TP-LINK (http://www.tp-link.us/products/details/?categoryid=&model=TL-WDN4800)
Using this adapter, I only have 3 to 4 bars and when I ran ookla speed test, I got 9.13 download and 5.24 upload
Using a laptop in the same location I have 5 bars...
