Hi, I would very much appreciate any suggestions to my problems below. I purchased an Alfa AWUS036H from Amazon to connect to an AP about 20 meters away through 2 walls. I was able to connect to the AP with a full signal (5 bars) However, browsing the internet was painfully slow and some websites did not load. The AP is connected to an ADSL line with 24Mb/s download and 1.5Mb/s upload. I tried 2 different AWUS036H. I tried them on 2 different computers and 2 laptops. I tried with a dual USB cable also but nothing worked. Even if it connected to the AP, it would sometimes show limited connection and would also disconnect randomly. I tried using it on both Linux and Windows 7 x64 and had the exact problem. I later purchased a newer Alfa AWUS036NHA and I have experienced the same problem. If it is connected when my computer is booting up, the POST freezes and resumes once it is removed from the USB port. Below is a speed test I did comparing the Long Range AWUS036NHA to the built-in card inside my laptop: The AWUS036NHA connects at 135Mbps Download: 0.26Mbps Upload: 0.12Mbps The Centrino Wireless-N 2230 connects at 26Mbps Download: 6.54Mbps Upload: 1.38Mbps Can someone please tell me if these cards are just like this or I am simply having bad luck with them? I need something that will give me good throughput speed as the built-in card. Thanks in advance.
