Hey
zkalra, maybe I can help. I to use a liksys / cisco usb dongle and personally it works great! Its an AE1000, capable of N speeds and dual band. Mine is connect at 5.0Ghz running 300Mbps and a signal strength of 90%. I'd say that is pretty good considering its jacked into an internal 2.0 port, over 30ft away from the router. Never drops connection either! Remember USB2.0 has a total bandwidth of 480Mbps so there is no bottle neck.

On the other hand PCIe2.0 reaches a staggering 4000 Mbps on a x1 slot. Potential is greater as long as the hardware you have supports such speeds. No wireless card on the market could use all of this bandwidth btw. IMO...a router upgrade would net you better speed, range, and reliability than an adapter upgrade. But if you must purchase one (an adapter) I have used
this one here many times for clients in the past, with great results. You will notice that the projected maximum speed is the same as it would be using your USB dongle you have right now (AE1200). Hence why I recommend a router, not an adapter.
But if you want to know one of the best internal adapters on a PCIe2.0 connection, here it is...
LINK... Great product no doubt. Totally pointless to get this or better unless your doing a lot of home networking (LAN) or streaming content (media) to other devices in your home.
I hope this helped and shed some light on the subject for you, good luck!
