Ever since I bought my Samsung N145 (which I love), I’ve always been annoyed with the problem that the built in wireless adapter rarely picks up Wireless N (802.11n) at 150Mbit/s. Instead, it usually picks it up at 65Mbit/s, which can often be annoying when transferring large files over a network.
However, Microsoft released a driver update (via Windows Update) in late August 2011 which seems to have resolved the problem.
It’ll be listed as an optional update in Windows Update. Unfortunately, Microsoft have provided no direct link to download manually. However, I can tell you that the driver ID is 20442151.
Download the update, install, and with any luck the problem should be solved immediately.
